Milan's Public Journal

© Welcome to Milan's Public Journal, weblog by Milan Živić - a personal cloud of short stories, both fiction and real, including honest reviews, travel guides, rationality and personal glimpses of the world. Also a lot of science, physics, astronomy, science fiction, history and reflections on religion and politics.

Giordano, Isaac, Albert and Stephen

Did you know that if you were standing on the near side of the Moon, and your weight is about 80kg on Earth, due to Moon's lower gravity, you would not be heavier than 13kg? You knew? Ok, did you know that Earth's and Moon's gravities combined gave you different weight on near and far side of the Moon? Slightly yes, but true. Earth and Moon are relatively small celestial bodies but this difference goes even higher if you move from the Moon to the Io or Europe for example as they are also tidally locked by Jupiter just like our Moon is locked by Earth. So if you thought that floating mountains on Avatar's Pandora are just a figment of writer's imagination, think again. Within right conditions and with presence of large mass(es) orbiting nearby, considering appropriate composition of the ground and biology of the species, who knows, it might be possible.

"If I have seen further it is by standing
on the shoulders of giants” - Isaac Newton*

We simply take gravity for granted. We only know it here on Earth where it is stable and friendly, but up there within some, for example, triple star system with close by multiple giant planets orbited by dozen of rocky moons each, it would not be far from common sense for some intelligent insect-like aliens over there to build their calendars based on gravity changes instead of planetary motion. Maybe instead of "July" they have 'month' called "Joy" when everything is light and happy and for "January", who knows, maybe they call it "Despair" when due to heavy gravity their wings are useless and all of them are forced to spend the time on the ground playing monopoly.

Well, aliens aside, when it comes to gravity it seems that it indeed is the last frontier in our understanding of the universe and our search for the ultimate theory of everything. Is it force like any other and eventually we will find gravitons that will fit perfectly within well known particle model? Will it be some kind of space time continuum property just like perforated highways in vacuum that is used for object's motion? Or the final description of gravity is still waiting deep below within quantum world and string theories. Or maybe it is something entirely else. Whatever it is, I am sure a day in the future will come when we will learn everything about it and maybe this breakthrough discovery will reveal the doors with possibility for solving more mysteries waiting in line, like dark matter and dark energy and perhaps even provide a ways of how to efficiently test all the theories that predict existence of multi-universes and multi-dimensions. If we look into our scientific past, it was always like that. Every scientific breakthrough is made on shoulders of another. This is exactly what sir Isaac Newton meant when he wrote a letter to Robert Hooke in February of 1676 and said "If I have seen further it is by standing on the shoulders of giants". Although, if we dig more in the history of two scientists and rivals of the time it is more than possible that Newton meant more with this quote than just it's pure meaning from 12th century originated from Bernard of Chartres.

Giordano Bruno, Isaac Newton and Albert Einstein

I know it is not really easy to make a short list of favorite scientists in the past that perfectly followed Bernard's simple truth but, you guessed, I will try nevertheless. I also decided to follow short story from last year called "Jules, Isaac, Arthur and Carl", about Sci-Fi novelists and science journalists and similarly I will choose only four scientists I think they were and one of them still is living and working simply ahead of their time and represent true pioneers in scientific community. With one exception. The very first one in the list is Giordano Bruno, Italian philosopher and mathematician who lived in second half of 16th century and literally gave his life for science and free thought. Understanding heavens in his time was challenging to say the least. Catholic Church found him guilty for heresy and on February 17, 1600 he was burned alive in Rome's Campo de' Fiori square. Inquisition put him on trial for his belief that Copernican model is only wrong because it includes center of the finite universe in close proximity of one celestial body. There is no center and universe is not finite, he said way too loud. Simply put, in 16th century, the only outcome of publicly saying that universe is infinite with no center whatsoever and that Earth is just one of wandering "stars" - were inquisitors knocking on your door accusing you for denial of everything holy and divine.

Giordano Bruno died in dawn of 17th century and he, along with lots of other scholars in dark ages and those before Christ, represent the base of what we call today modern science. His name in my list merely impersonates all the scientists from old Greek, Persian and Egyptian era starting with Democritus, Eratosthenes, Aristotle, Ptolomy, Hypatia, Azophi followed by Giordano's contemporaries Galileo, Copernicus, Brahe and Kepler and many others. These people are the giants from Bernard's and Newton's quote. Every single one of them made a step toward final understanding of the Universe and how it really works. Even when they weren't right because of lack of precise tools and instruments or simply because of false interpretation of natural laws, their theories revolutionized the ways of thinking and provided next giant in the chain to continue the path.

Einstein changed science's perception of gravity**

Perhaps the best illustration of how one scientific chain of thoughts is evolving in time is how 'chain of giants' were dealing with discovery of gravity and understanding oh how it works. Started with Aristotle and Ptolemy, planetary motion and relations in general between distance, speed and time of a moving body culminated with Galileo and Kepler who discovered basic principles and proved first theories in experiments. It was first half of 17th century when almost all scientists of the time accepted heliocentric system and started to understand that motion of a projectile is not that different from the motion of one big celestial body, like Earth's around the Sun. By the time Isaac Newton started to write his famous "Principia", everybody accepted the big picture of the system in works. That one celestial body is maintaining complex motion around its own axis and orbiting larger one in elliptical path. Nobody knew why though. And how. Newton simply provided next step in the chain with his law of universal gravitation. What he mathematically presented is how gravity force acts between two bodies. No matter how big they are, attraction force between every two masses exists and can be described with simple formula in relation of their masses and distance between them. If you were a student of astronomy, with knowing only this law, combining with Kepler's third law of planetary motion that connects time with elliptical property and with known motion and masses of planets in Solar system, you would easily be able to calculate the path of a small spacecraft launched from Earth toward some destination in outer solar system using little rocket fuel and only gravitational forces of planets during flybys and temporary orbits. And all this calculations would be based on formulas almost 400 years old!

With Newton we now know why bodies attracts to each other, but we still don't know how they do that. Within particle physics, today we know great deal about how 'forces' perform or how they operate deep down inside atoms. In other words, each force is produced by fundamental particles that act as carriers of the force. Like photons that are carriers of electromagnetism. Various experiments in large particle accelerators also detected carriers of strong and weak nuclear force but gravitons are never found. Whether or not they exist or we are still missing something fundamental that will explain gravitational 'force' or whatever it is, time will tell. However, after Sir Isaac, one more giant stepped to the scene last century to add more light to the gravity phenomenon. You guessed, it was Albert Einstein with his theories of relativity. Even thought Newton's law works perfectly in both small and big scale, great scientist failed to understand relation between mass and space and time continuum, He was convinced that time is absolute and that space is fixed and they both have nothing to add to the system operating within. Einstein's general theory of relativity goes one step further and provides mathematical equations of flexible space-time that simply bends in presence of large mass. Not only that, but mass of some body is also flexible and depends on the motion. It increases with acceleration in speed and it goes toward infinity if the mass tries to travel with speed of light. The saga about gravity continues and if you ask me, I have a feeling that gravity is more than a force. Acts like one for sure, but maybe, just maybe, there could be a bigger story waiting to be revealed in the future. Something that would open the door for more questions and pending answers.

Hawking taking a zero-gravity flight in a "Vomit Comet"***

As it seems this story focus is on 'giant's from Bernard/Newton quote, especially for their contribution in understanding 'the heavens' and it is surely hard to pick just few of them over the centuries in the history of modern science. Perhaps, the best description of how and where scientific community evolved in today's phase I read at 'The Official String Theory Web Site':"Science in general and physics in particular rely on the strength of an entire community of critical partners in slicing and dicing through speculation and fantasy to get to the part where we start effectively describing Nature".

Perhaps, the scientific world after Newton and Einstein changed toward pure theory-proof approach, while before, due to lack of precise tools and credible experimentation it was not easy job to distinguish scholars between true scientist and plain philosopher. In conclusion, after picking Giordano Bruno to represents all true scientific minds from Aristotle to Newton, emphasize Isaac Newton and Albert Einstein as one of those brilliant minds who gave breakthrough contributions and enlighten the path for next generations, I feel that would be only unfair not to mention Niels Bohr for his breakthrough in understanding atoms and subatomic particles, James Clerk Maxwell for his theory of electromagnetism, Richard Feynman who dug more than anyone into quantum world and many more who lived in past two centuries. Lastly, among all the living scientists today who are walking among their paths today on the shoulders of their great colleagues from the past, the job of picking just one whose name would easily represent the entire community is fairly easy. It's Stephen Hawking. What slightly distinguishes him from Roger Penrose, Steven Weinberg, Peter Higgs, John Ellis, David Gross, Edward Witten and all the others who are actively searching for the ultimate theory of everything, was his work on mathematical description of black holes and breakthrough discovery of their radiation within research of general relativity. And, of course, because of his book "On the Shoulders of Giants" with original texts from famous scientists and their publications. It is amazing to learn about personalities and chain of thoughts of great minds who lived 400 years ago. Highly recommended.

Cyberpunk of Altered Carbon

In almost all Cyberpunk masterpieces in literature, comics, movies, games or whatever media exposure we think of when it comes to this genre, the settings is familiar. Dark atmosphere in both social and technological aspect of the story with dystopian surroundings and thin distinguished line between all characters within, no matter whether they are good or bad. I can't tell exactly why, but despite all the prosaic backgrounds and used stereotypes, I actually like this literary movement, perhaps because of the fact that people can't be really divided into good and bad per se. We all are combination of all possible adjectives out there and their summary is what makes us what we are. Actually, this is more accurate and closer to the truth compared to the "normal" or "usual" fiction with its ordinary hero-villain relations and idealized characters. Of course, like in any other genre, there are many poor and unmentionable works but also couple of those masterpieces, like in the world of movies, the famous Ridley Scott's "Blade Runner" or "Neuromancer" by William Gibson, in the world of science fiction novels.

Surely, the mantra of almost all Cyberpunk science fiction is advanced technology, placed in not so far future, exploiting the ultimate fate of humans along with major role of corporations that are developing and deploying it to the people. Actually one of existing nature of nowadays corporation-technology pair inspired me to start writing this post in the first place and perhaps some of you already guessed, it is current stage of social networks and the world they became after promising couple of years after their invention. In my case, the beginning of socializing the internet was inspired by establishing and experiencing new virtual friendships and new ways of spreading ideas along with simple feeling of participation in something futuristic and big. However, after years of maturing, it all went in very different direction. The endless stream of news feeds without quality conversations replaced the great main idea along with commercializing the entire thing. Today, with some of the networks, you can even buy likes or force people to read your piece not by its quality but instead by buying appropriate keywords. In past couple of years I found myself too many times in front of the screen rhetorically asking one simple question "Why, on Earth, am I reading this?" and often wondering what happened with my own interests and why I stopped searching them directly and instead waiting for them to appear on my customized social network feeds?

Further trouble with social networks, once joined, is that it is very hard or even impossible to leave. With some networks, deleting is not the option at all, only "deactivating" your presence and leave it intact on the company's servers for who knows what reasons. With others, you can't even deactivate your account without deleting other useful services that are too heavily connected. With all of those with actual "delete" button, you have no proof that your virtual past is really deleted and not just hidden behind the (fire)wall of corresponding corporation data center. In the aftermath, you have to ask yourself whether or not this behavior is the dawn of the Cyberpunk future we read in novels or just a curved present that is going to eventually fade out and be replaced by something new.

That's how I see the present day but to continue with the main topic, let's see how Cyberpunk authors deal with future evolution of the almighty internet and computers of the tomorrow. If we just glimpse to the technology behind the scenes of the Cyberpunk world, coated in heavy noirish detective story with a little or heavy emotional connection between main characters and with lots of not-necessarily futuristic weapons and tough fights, we can see one possible (or plausible if you will) vision of the near future where humans can easily become nothing more than just a slaves of advanced technology and mediocre lives within the system that can't be possible to escape from. Just take for instance Gibson's prediction of futuristic internet that will continue to "offer opportunity to waste time, to allow us to wander aimlessly, to daydream about the countless other lives, the other people, on the far sides of however many monitors in that post geographical meta-country we increasingly call home".

In the cyberpunk fictitious world, worldwide network would also be responsible for the very existence of the artificial intelligence, matrix like cyberspace with vivid virtual reality, robots and various machines that will be doing boring things for us, cyborgs with applicable neural interface with host computer augmented by nanotechnology and like in "Altered Carbon" by Richard Morgan, potential ability to digitize full personality or entire consciousness and store it for eternity into home computers or even other bodies. "Altered Carbon" came this year on Netflix in its amazing motion pictures version and it was extremely good. Imagining cyberpunk future by reading only is very hard, even for us technology geeks and TV shows or movies are always welcome, especially if they are made in such amazing production like the one behind Takeshi Kovacs adventures on futuristic Earth.

Now, interesting question is should we consider cyberpunk as a pure entertainment or we could safely put it in the same basket with original and genuine Science Fiction as it was in Jules Verne's or Arthur Clarke's time with expectation of some of its predictions to become true? Well, if you ask me, even though we are facing here with dark predictions rather than something good and promising for future generations, we simply can't rule it out. We are already taking technology for granted and if this trend continues I can't see how can we avoid all the dark sides that comes within. Invention of AI and nanotechnology along with super fast (quantum) computers will bring us inevitable breakthrough foundation for the society with humans not being the ultimate player anymore. However, I don't think we should be afraid from upcoming and remarkable inventions in science and technology. It will change our lives yes, but surely it doesn't have to be overnight or all bad. Actually, I think it will bring more benefits to us than side effects. So, no, I truly want to believe that dark settings from cyberpunk worlds will not become true. Not on a great scale, I don't think so. We will wait and see. Well, maybe not you and me, but some future generations for sure.

However, what I am more afraid of are humans themselves. The corporate part of the story. Many villains in cyberpunk stories are hidden behind the corporations and their agendas and the natural question pops to mind - is there any real danger of transferring the power from political system of nowadays democracies toward corporations and their pure financial interests? Or to put it in simple words, is it possible that in any futuristic world scenario, future companies compared to today's Google, Microsoft, Apple, Gazprom, Wal-Mart, China National Petroleum, Leading German Car Manufacturers, AT&T, or any other industry lords you can find in below reference page, can be strong enough to take over the power and completely restructure the world as we know it? I am sure this is very hard to imagine from current point of view, but I am still having goosebumps every time I give I thought toward the possible world in the future where current political system weakens enough to the point that it could becomes vulnerable to the ultimate collapse with all the corporations waiting with their jaws open and ready. If you browsed my blog before you probably already know that I blame politicians and politics in general for all the dark times in the history of mankind, but if I could think of anything even dangerous than that, then it would definitely be bunch of wealthy people behind the catchy corporate names with only profit in their minds and the only goal to grow even bigger and wealthier than all the competition.

5th Grade Coding

It was different when I was 5th grader in many ways. Learning how to code was not in the realm of elementary schools back then. Computers were simply too large and expensive for kids to play with and having a good teacher who knew programming languages was rarity. So I was in a bit of a blur when I pressed "P" key on, my first, just unboxed, brand new and state of the art, Sinclair ZX Spectrum keyboard with amazing 16KB of RAM memory. It reacted immediately and at the bottom of the large home TV, it said "PRINT" followed with blinking black square cursor. "2+2" I added and hit "ENTER". It was like magic seeing "4" printed on the screen next instant. The magic of course was not in the correct number. It was rather in the unworldly feeling I got that exact moment of what would come next. What I could command it to do. It was like I found the door of the amazing new world and the door started to open wide!

Soon later I learned more, especially commands like "INPUT", "IF", "FOR", "GOTO" and those more interesting ones, like "PLOT", "BEEP", "DRAW" followed with even more exotic directives like "PEEK" and "POKE". It went without saying that I occupied living room TV for too many precious hours every day, so my parents eventually bought me a small 12", black and white TV, so I continued with my self-coding BASIC lessons (and with games) on my little 5th grader's desk in my room.

Today, in Viktor's 5th grade time, three and a change decades after, introducing programming world is a bit different. The main tool is now the browser and the language evolved into VPL or Visual Programming Language. This practically means the coding is done by creating and juggling program elements within graphical environment. It is far more intuitive than doing it with words and I can't see any obstacles that, in one way or another, what kids are doing today will be the main way of coding in the future. How far in the future is debatable but just compare the function created by one simple VPL in above screenshot with the following code that does the same thing and I am sure that you don't have to be coder in order to understand what's better for 5th graders to start learning programming. And not just for them.

public void NectarCollection() { for(int i=0; i<=3; i++) { MoveForward(i); for(int j=0; j<=2; j++) { MoveForward(j); GetNectar(j); } TurnRight(i); } }

VPL coding was not the new idea. Programming languages are slowly pushing in this directions for some time. For example, within my professional world, which is fully oriented towards the data manipulation, unified communication and business in general, the main programming tool is Microsoft's Visual Studio with its first version dating way back in 1997. It's current release is named VS2017 and it's about tenth or eleventh edition by now, but despite its name very little inside is truly visual. To be honest, there are some graphically operated bits and pieces but still, good old VS is still using the text editor for it's main weapon.

However, the generation gap and software development within the internet network brought even more opportunities for nowadays 5th graders. With their VPL blocks they don't have just to draw bees and robots on the screen and task them to do things. They can do that with actual robots on the dining table! I learned about these programming aids several years ago and it was only a matter of time when the big players would step into the arena with much cheaper investments. This year that was exactly what LEGO did with their first robotic kit with pre-built 'boost bricks'. Anyhow, "Lego Boost" arrived last week and this weekend was all about "Vernie, the Robot", the first robotic creature Viktor made from the box. Not even the expiring chickenpox ruined the playing time and he spent almost entire seven hours building, testing and filming it. It is suffice to say that we both recommend this learning toy more than any other Lego before. The heart and the brain of the set are those three smart bricks that combined represents a Bluetooth hub with movement and optical sensors powered with pretty strong motors that drive not so little robot. The hub is connected to a phone, tablet or a PC and all the VPL magic is made inside equally amazing and intuitive app.

Furthermore, the most popular VPL for nowadays 5th graders education, MIT's Scratch project, with additional helper app (Picaxe S2Bot), is now able to control Boost creatures. To be precise, new Boost VPL blocks are able to control all three motors in the hub along with dynamically acquiring sensor data. In first video Viktor's and me attempted to control the distance sensor and to avoid obstacles on the Vernie's path. It is rudimentary and raw, after all, this is just a sophisticated toy, but nevertheless it opens many new ideas for custom built sets for the future.

But the story with Lego and Move Hub went even further with open source projects on GitHub developed by enthusiasts, such as Python library created by Jorge Pereira. Viktor and I wanted to make a good use for our old USB gamepad to remotely drive Vernie so we modified Jorge's code to test it out and it worked perfectly. The second part of the last embedded video shows what we did and what can be done with Python within Ubuntu environment. In a a word or two, we had a great time and learned many new things, along with how to use Python to answer the web request from HTML page. Viktor made a simple game out of it by using images from his favorite YouTube channels.

If you ask me to conclude something smart from all the VPL magic for the present time and nowadays 5th graders compared to what I had in my time - all I can say is this: "Just imagine what will be inside the "Lego Boost" alternative in thirty years from now. I wouldn't be surprised if 5th graders of the future start talking to their creations while coding their rudimentary AIs."

Anthropocene of Movies

There is a debate whether or not Holocene, the latest geological epoch is already finished with ultimate human impact on Earth's ecosystems, which started along with industrial and technological maturity in recent past. Many of us believe that new era, suitably named Anthropocene is what we are living in already. With technology rise, it looks like humans already changed fundamentally to the point of incompatibility with our distant ancestors. Perhaps we are indeed heading toward rapid evolutionary change, like in the latest Dan Brown's novel "Origin", but this premise is way more suitable for another science fiction I have just watched (for the second time). I am sure that for all of you who like intelligent movies, a long anticipated sequel for "The Man from Earth" finally came and it, without a doubt, opened the Holocene-Anthropocene transition for John Oldman, a 14000 years old man, who also, like entire humanity, seemed to be going through the change of his own.

The movie distribution has just started and I am not going to spoil the content but I will tell you that after I watched it for the first time my initial thought was that there was many "I didn't see this coming" moments, looking from the point of view of the first film. After watching a movie for the second time, and I really needed to do it to clarify the image, my impressions didn't change a bit and I truly hope Richard Schenkman's wishes for the sequel TV show will come to life. I would definitely like to see what happens next. Perhaps little more science than religion could spice the script with additional direction. After all, Anthropocene epoch is a scientific achievement, which is maybe faster in development than what human society can handle at the same pace.

"The Man from Earth: Holocene" comes with one more twist when it comes to distribution of films in general. It uses donationware, a licensing model originates from the software publication but with one more add-on, to stay with the IT vocabulary. If you don't like it, you get full or partial refund of the small amount of money taken from your card. This is exactly what I speculated once before on the blog, back in 2012 when some sort of political attack was launched after Wikipedia. The story went toward anti-piracy war and distribution of movies and I complained that my time was not free to be wasted and after watching some movies I felt like I would like having some system that would provide some sort of refund for both of my lost time and money.

"The Man from Earth" and "The Man from Earth: Holocene" are now part of this donationware-like system and the distribution of both films is made by a fairly new website called MovieSaints and in their words, this is the place "where people can discover and watch compelling independent films from around the world. Viewers can support the filmmaker/creators if they like a film and get a refund if they don't like it." I would really like to see the success of this for the future and not just for small independent projects but also for the major franchises as well. After all, internet is also one of those scientific achievements that are forcing full closure of the Holocene epoch and this donation-refund system, if succeeded, could have power to dramatically reduce intermediaries and pirates.

Ever since the internet arrived and spread everywhere as the ultimate carrier of the intellectual property of various kind, along with came the business, politics and all the other side-effects and struggles intended for squeezing pennies or votes out from the little man behind the screen. Of course, when it all started, the stage was academic and most of the suits, whether they were hiding behind various business acronyms or political parties, stayed outside. The internet was small back then and not important from their point of view. It was also more honest in the nineties before the new millennium. Well... Almost. The web pirates were there from the beginning.

I remember I wanted to contribute with what I did best at the time and created several desktop applications for home users and small companies. It was nothing special, just couple of ActiveX libraries to help Internet Explorer to use email functionalities and sharing files more easily or, for example, a very nice application for FM radio stations - the producers' tool for organizing "on the air" time with custom lists of MP3 songs and commercials scheduled to be aired automatically without host or technician. For small applications like those, it was popular choice to go with "Shareware" distribution. It basically meant the applications were free but slightly limited in functionality and if small fee was paid, I was creating the unlock code that provided restrictions to go away. Even without that, all apps were useful enough so the end users with paying for the code were actually more sending the note that they are really satisfied with functionality. The unlock code was pretty simple - just small math equations that verified that serious of numbers corresponds with the math result. Imagine my surprise when almost day after I posted applications online, the pirate sites included license keys for all of them.

At the time, the internet market was restricted to IT only, but today, it became fast and almost everything could be stored and streamed, without obstacles from technical point of view. The obstacle now is the fact that businessmen and politicians joined the pirates. Today, if you wrote the book, composed the music, created the software, had a breakthrough in science, made a movie or contributed with any kind of intellectual property and you want to earn little money from the effort, you can't do it alone. Your significant share is taken by businessmen or stolen by pirates or taxed and/or forbidden by illogical laws that favor others. Not to mention lawyers and bankers that also parasitically live within the system and take the share with any transactions or legal processes.

In conclusion and to put everything in perspective, what people behind MovieSaints are trying to do, at least with small independent movies, and what was the main idea decade or two with shareware concept, now with addition of refund policy, is taking one step further. It does require a little bit of honesty to work. Something that is not the prime feature for the average human being but I am sure that, deep down, everybody possess it. Moreover, along with honesty for this system to work, it does require other distribution companies to follow but to see it running on the bigger scale at least one big player in the vast internet arena must join.


Quantum Weirdness

Rarely I've got a chance and real opportunity to revive an old article from the past and to update it to fit better in the present day. Actually, the quantum weirdness is still where it was four years ago - science is not something that changes over night especially with quantum mechanics, so I am not going to update the post with any new physics or breakthroughs. Instead, what 's new and what pushed me to repost today is one extraordinary novel in the field. The book that kept me from sleeping last weekend was "Quantum Space" by Douglas Phillips and in short it is by far, one of the best titles I read this year. It is one of those true sci-fi stories that follows the real science and in this case the weirdness of the quantum world I wrote about in this post and I would add one of those articles I enjoyed the most writing in the history of the blog. But, before couple of my glimpses to the book itself, followed by my warm recommendation and especially if you want to read it yourself, please continue reading about physics itself. This one definitely requires some knowledge to understand it fully, so let's start with some weirdness of our own macro physics first.

It's very well known that the world we live in are driven by two sets of rules or physic laws. The one for big and the one for small. We don't need to be rocket scientists in order to observe our big world surrounding us and to notice all the laws we obey to. For example if we drop a book and a feather and let them both hit the floor separately, it is obvious that book touches the floor first. However if we put feather ON the book and let them fall together, they will hit the carpet in the same time. Well, the book will still hit the carpet first, but if you try the experiment you will know what I mean. This simple experiment was itching Galileo's mind centuries ago when he discovered one of the fundamental physics law stating simply that mass of the object has no influence to the speed of free falling. But, we can ask ourselves next, why the feather traveled slower toward the floor if dropped alone? Because of the things we cannot see. The air is blocking it. To learn what is happening with the feather during the fall we have to go beyond our eyes. We need science and experiments to discover why small molecules of the air would rather play with feather than with heavy book.

Was the book/feather experiment weird to you? I am sure it was at least little weird if you are seeing it for the first time. We simply accept things for granted. What we cannot see, like the air and its little ingredients in above experiment, we tend to exclude from our perception. If this was little strange and intriguing, lets go further to the world of even smaller and compare it to the world of the big. For example, in a mind experiment, we have a 9mm gun and shoot toward the wall with two holes in it, both with diameter of 9mm or little bigger. If you are Olympic champion in shooting you will, of course, need only two bullets, one for each whole. In the world of little if we use a gun that shoots electrons toward a wall with two adequate holes in it, you would probably think that we would need two electrons to hit both holes, right? Nope, we need only one. Believe it or not, one electron goes through both holes and we even don't need to aim too perfectly. No, it doesn't split up in two and use each half to pass the holes. It goes through both holes in the same time. In fact, if we had three or more holes on the wall, one single electron would go through each one and in same time use all possible paths toward the destination. Perhaps the best illustration what happens in this experiment is presented by "Stephen Hawking's Grand Design" documentary made by Discovery Channel.

And you thought feather on the book was weird...

Space Humor

It happened long ago, in the dark ages of CRT monitors, when I first received a short forum message with :-) at the end. I stared at the message for a long minute(s) before giving up of decoding its meaning. It came from the well respected friend of mine so I responded with short reply:


"You have to turn your screen 90 degrees clockwise." Answer came promptly.

My CRT was large and heavy and it looked way too dangerous to tilt it that way so after little brainstorming the problem, I concluded there's a better way of achieving the same goal.

I tilted my head 90 degrees anticlockwise.

"Aaaaaah!!!" I said promptly and after realising the picture, big smile on my face slowly morphed into loud laughter. So I typed back:


I didn't have to wait long for the next message:


"What?" - I quickly copy/pasted my earlier message but realised I was too not informed about new internet fashion so I canceled the message and opened new Netscape window instead, called and 'googled' new internet words. Ever since then LOL is on the top of my list of favorite acronyms. Along with all those cute ASCII faces. ;-)

In my case, and probably with many people as well, laughter is one of those most powerful cure for everything. The all mighty vaccine for all diseases. Especially boredom and poor moodiness. LOL moments, somehow come naturally with live social occasions and in movies but in books they have one extra dimension. I really can't explain why is that. Perhaps funny moments in written world often come unexpected and more genuine. Take for instance Andy Weir's "The Martian" - the hilarious parts in the book were genuinely funnier than in the film. At least with me... Well, nevermind that, so to get to the chase, last month I read three extraordinary funny books in the realm of science fiction and space exploration. So here they are in this short review, sorted by the count of LOL moments I had during reading. In descending order of course.

The first one was "Where the Hell is Tesla?" by Rob Dircks. I stumbled to this one by accident and boy I am glad I did. Nikola Tesla is one of my favorite men in the history of people, science and engineering and here in Serbia, especially during my childhood, Tesla was idealised and always portrayed in too serious manner. Anyhow, when I saw the title with Tesla playing the major role in the comedy story I couldn't resist and I didn't regret a single penny. It was by far the funniest book I read in a while. It had it all, decent science fiction based on cutting edge scientific theories of the multiverse, the romance and friendship within different storylines, cute aliens, sci-fi battles of enormous proportions, great style of writing, Nikola Tesla in the most entertaining meaning of the word and of course ... Chip. I am not going to spoil the reading for you but I will tell you this. On one occasion, I almost dropped my Kindle on the hard floor caused by one of the strongest LOL moments. Enough said.

The second is "Jazz of Artemis". In context of today's post, this is how I would name the book if I was Andy Weir. Of course, his new book is not a comedy per se. But it is not "The Martian" as well. However, in the realm of the funny moments it is a decent sequel. Way better and much funnier. Jazz is ... let me find the right word ... extraordinary girl on the multiple levels. I enjoyed her adventures fully and I do hope for the real sequel this time. I mean with Jazz around, what can go wrong on the Moon? I really hope there will be the movie after this one as well but not solely because of the entertainment part and all the LOL moments, especially with that Svoboda guy and his ability to manufacture various devices that do or do not belong to ESA blueprints and worksheets.

But seriously, what Andy Weir did with creating a fully functional city on the moon with both working technology and society organisation is amazing and also extraordinary. It definitely deserves the motion pictures and I am sure filming the movie that takes entire story and action on the moon is another challenge. I am sure Ridley Scott is buzzing his mind with this as we speak.

Finally and to use the cliché, the last but not the least comes the good old British humor. Something I grew up with all the great TV shows like "Monty Python" and "Only Fools and Horses" or short comedy sketches and skits by Dave Allen, Benny Hill, Rowan Atkinson and others. But in the flashlight of the parody novels the throne is still with Douglas Adams and his "The Hitchhiker's Guide to the Galaxy". This was the first book I experienced LOL moments with, way before LOL acronym was ever invented. "The Worst Man on Mars" by Mark Roman and Corben Duke was probably the most similar novel I read in a long while.

This is also a parody, but not really as much as the famous predecessor. This book follows the plausible science fiction and doesn't go into wild imagination, like the restaurant at the end of the universe or "42". I really did like many technological backgrounds inside, like artificial intelligence or space elevator for example. But the humor with this one comes first and the robots in their sitcom on Mars are something I do recommend warmly.



Here’s How Augmented Reality is Going to Rock Our World

Augmented reality (AR) is on the cusp of changing the world. The technology overlays imagery and information about our physical surroundings on visual devices like tablets, mobile devices, and wearable hardware like glasses. Everything from how we shop to technical training will change as advances in AR create new applications in every aspect of our lives.

Apple has been at the forefront of the AR trend with the introduction of ARKit, a framework tool that enables AR mobile web app development for the iPhone and iPad. The software uses the device’s camera, motion sensing, GPS data, and more to explore the physical world around us and add new, innovative ways to interact with it. Here are other ways augmented reality is changing the world as we know it.

The software uses the device’s camera, motion sensing, GPS data, and more to explore the physical world around us and add new, innovative ways to interact with it. Here are other ways augmented reality is changing the world as we know it.

The Application of AR Will Spread Everywhere

Gamification is a great way to introduce new technology to consumers. It’s fun, entertaining, and a proven way to teach users new applications. Probably the most well-known AR mobile app is Pokemon Go!, which introduced millions of consumers to the concept of augmented reality technology.

The same ideas that made this app so successful can be applied to the workplace. For instance, it is possible to gamify the work process, allowing employees to earn points and rewards as they complete tasks, outperform, and improve their results. Gamifying enhances engagement and employee performance.

The potential for improving lives, however, goes beyond simple gaming. With AR, the workplace can be transformed with greater safety and efficiency by giving staff access to vital information about their surroundings. Things like warnings about machine operations, tracking items within a warehouse, or expanding situational awareness in chaotic environments can contribute to better and safer spaces for employees.

The applications AR has for life-saving are also vast. From military in the field to underserved remote areas of the world, medical training and guidance can become an augmented reality experience that will save time and even lives.

It Has Even Greater Effects on Retail and Design

Another huge impact from AR will be in the world of commerce and e-commerce. AR mapping of retail malls and stores will turn searching for any item into simply following of a virtual map to its location.

Through various scanning techniques, shoppers will be able to use their own facial features or body types to virtually try on merchandise. Since the inability to try on clothing or shoes account for over 30% of Ecommerce returns, the online market will expand and satisfy customer needs more easily. They can now offer products that will perform as expected, clothing that will fit, or determine if a purchase will fit in the space that you envision.

The design world will be turned on its head as AR technology continues to develop. Products can go through an AR modeling process that will skip the physical prototype phase, saving time and money and allowing for design improvement and enhancement.

3D models will become virtual experiences, such as a car designer sits inside a car and sees the impact of layout. Or, a furniture designer tests designs for ergonomics or structural issues without the need for physical samples.

AR Has an Enormous Financial Upside

From a business point of view, the stakes are high for augmented reality. Broadening markets, improving customer satisfaction through quality sales, and developing marketing ideas that will create more user engagement and loyalty all will improve the bottom lines of companies. The revenues for companies investing in AR technology that integrates with their products and services is expecting to explode from $23 million today to almost $50 billion in less than five years.

Utilizing and understanding AR technology now will provide businesses with revenue-enhancing opportunities ahead of the competition. It will also provide consumers with a new way to engage in aspects of life ranging from gaming to the workplace.

AR has arrived and will expand at a breakneck pace. As consumers and employees, we will see our world change in ways that will save time and money, enhance our everyday experience, and move us into the world of the future.
