Choosing Planets

Let's turn our imagination to the edge and do something different today. We can call it a thought experiment, a childish game, a daydream, science fiction, pure fantasy, or whatever we want, but let's move the boundaries far away from Earth, far away from our solar system, even farther from our galaxy, and do something wild.

Let's choose a planet.

Or, to be more precise, let's select one in the vastness of the cosmos and move away from this Earth and start new life. Of course, in daydreams we are allowed to do this just because the imagination is what our species differs from others on Earth.

Ok, to begin this little endeavor, we need a little astronomy to start with. What we know for sure is that our galaxy alone contains more than 200 billion stars, the majority of them not so different from our Sun, and by using a basic statistical study based on the planet finder's microlensing technique, there are approximately 100 billion planets orbiting them. Perhaps more. Multiply that by a factor of billions of galaxies in our universe, and you'll get that there are far more Earth twins out there than living people on Earth. There are planets for everybody's taste. So let's start with the planet's basic properties.

Choosing the World

It has to be huge, much bigger than Earth, maybe twice as big in size or even more, to harbor as many people as Earth today and still have plenty of room for many more. To be something like in Canada's distant regions today with only up to a thousand people per square kilometer. However, its composition must be radically different than Earth's, as, in my imagination, it has to maintain gravity more or less like the third rock from the Sun. After all, I don't like to move there and look ridiculously dysfunctional when it comes to, say, simple walking. So fewer heavy elements inside, please, and let it be around the famous, well-known number of 9.81. More or less. So no radical changes when gravity is in question, but I would choose the one with radically fewer water layers than we are familiar with within here. Don't get me wrong, I do like water, and I would like to have plenty of it all over the place, but with no oceans or large seas. Rivers are ok in any variety, lakes too, and small seas are also fine, but please no oceans. Nobody needs that. Hey, it's my planet; if you like oceans, find your own, or don't move anywhere; there are lots of oceans here.

Basically, there must be one giant continent in Norway's style with lots of rivers and lakes and small seas with large bays and calm weather. One rotation cycle could be a little longer than Earth's, but not so much over 30 hours. You can't get rid of old habits that easily. Like Earth, it needs to have a slightly tilted rotation axis to provide longer seasons and temperature changes over the year, with a revolution over the main star similar to the one in Mars or approximately twice as long as Earth's. Earth-like atmosphere and its greenhouse effect would provide a temperature range over the year to be a little milder compared to our native planet, maybe no less than -10°C in harsh winters and no higher than +30°C in summers. A tilted axis and position within the habitable zone of the mother star would also provide no big differences between the planet's equator and pole regions. What else? Oh yes, it has to be protected with both a strong magnetic field and a couple of perfectly positioned giant outer planets from both radiation and looney asteroids and comets. It could also be part of a binary star system, where the second star could also provide additional protection when it comes to violent cataclysmic events in the neighborhood. Last and surely not least, it has to be green all over the place. Extremely suitable for cultivation of various kinds of anything possible. The geography of the planet could be variable with both long valleys and mountains, just like in our home yard.

Humanoids by Star Trek "design"

Do you like my paradise so far? In a way, it was not hard to set the basic astronomical properties of the star system and planet itself. However, a bigger challenge comes with defining the demographics of the planet. You might not like it anymore after I continue and say that I would like the planet to be colonized without any domesticated intelligent species. Why? First of all, it wouldn't be right to find a desirable planet along with at least one dominating intelligent species already evolved there. It would be like colonizing the Americas and killing or putting the population into reservations. We've been there. It's just wrong. Secondly, and probably even more important, is that I would like to share it with other intelligent species. Preferably humanoids. Not mandatory, though. That way neither would be in a position to set a flag and say, "This is mine; everybody else is not looking like me; go away". Basically, in my vision, everyone intelligent who would like to come and build a house is welcome at any time as long as they sign some sort of "sharing" agreement. Something similar to the Antarctic Treaty System we are having here on Earth. Basically, the colonization idea would be comparable to the Earth back in dinosaur time, when all the aliens missed the opportunity to colonize it when no domestic intelligent species existed to claim it for itself. Or they didn't miss it at all, and we are actually them and have never been native to this planet.

So how would all that sharing look like, and what kind of civilization am I talking about? There are so-called Kardashev scales defining possible civilizations out there, dividing them into Types I, II, and III, and it, by definition, represents a method of measuring a civilization's level of technological advancement based on the amount of usable energy they have at their disposal. All three types are far away from the civilization of humans as we know it today, and all three are suitable as potential residents for my planet. By the way, let's call it in further text "M." Accidentally, although I first thought of my first name's initial, it is titled more accurately according to the planet's classification seen in Gene Roddenberry's Star Trek. Anyway, the point of using high-end civilization in my story is that young civilizations like ours are simply not suitable. Why? Several reasons, actually. First, it seems that a big amount of mutual tolerance is needed for the sharing principle I have in mind. All desirable intelligent species have to be evolutionary mature and unburdened by racial, religious, and any other interspecies differences. Additionally, the population must be technologically advanced. The system on the planet would be as simple as possible; there would be no countries nor any kind of political organization, no governments of any kind, nothing like on the third rock of our solar system. There will be just one institution, planetary-based, with just one treaty where all colonists have to sign, and it should be pretty simple. If you want to live there, you would have to choose the land that is free and yet unoccupied, claim it yours, and the only condition to keep it is to produce zero waste outside of its boundaries. Otherwise, you can do whatever you want with it—create your dream house, build a school, trade market, entertainment facility, anything at all—as long as you play fair in relation to others.

ISS 3D Printer and first 'emailed' socket wrench

There will be no cities, as the technology at everybody's disposal would provide transportation to the most distant part of the planet easily, safely, and fast. I see smaller settlements, though, based on their mutual benefits and relations. There will be no sports, at least not in the form of the ones we know on Earth. It would be extremely unfair to play, for example, basketball involving multiple species with different masculine properties. However, the technology sports would survive, like races or any kind of recreational activities. Advanced technology in everybody's home would provide planetary and interplanetary networks of various communications; there would be no need for many supporting factories except for basic ingredients, as home computers would be equipped with state-of-the-art 3D printers capable of producing both simple tools and complex machines. The same home computer would also be able to use food replicators for creating food and food supplements. I don't like the existing concept of killing other species and using them for food. Cultivation and planting are perfectly ok, and each household would possess its own greenhouse for growing appropriate food, but I expect high-end civilizations in evolutionary terms would solve "the meat" problem, and I am not talking about a vegetarian diet.

Of course, the main star system would be well explored, with several outposts built for several purposes, along with mining outer moons, other planets, and asteroids in search of all necessary ingredients for planetary life, along with a variety of orbital activities for planetary residents, including entertainment.

Unfortunately, choosing a world to move is still just a dream. Reality still resides far in the future. Nevertheless, I wonder if such a world already exists out there in a far, far... You know.

The World of Extraordinary Apps

Smartphones in this touchscreen form have not been among us for a very long time. Even though before the year 2007 the origin of app-based mobile phones existed within a variety of BlackBerry brand models and prototypes in Nokia and NTT DoCoMo labs, only after capacitive touchscreens matured enough to be industrialized and embedded into popular handheld devices did they start to be really interesting and competitive. Today, after only a decade, the smartphone market is one of the most valuable on the planet, and app stores have reached the limit of 2 million per platform. There are literally zillions of apps out there, and browsing the app libraries became the real effort.


Anyhow, today, and a dozen years after the first touchscreen smartphones (LG Prada and iPhone) hit the stores, Viktor and I decided to film/write about a dozen apps that are a little bit unusual and extraordinary compared to those that are used on a daily basis by most of us.

To start with, let's first present the latest video from the zViktor22 channel and our recent collaboration. I hope you would like it, even though it ended pretty long, almost half an hour in length, and if you haven't heard of some or all of the apps we were testing within, it could be entertaining and educational. If it proved that way, you know the drill; please like and subscribe and/or add some comments at the end. It would mean the world to us.



Before I add a word or two to describe screenshots from the apps, it is only fair to mention one more app that we tested with this video creation. Suitably for this title, this entire video is edited in an app as well. The name of this really great app is Animotica, designed for Windows 10, and all I can say is that it is a valuable competitor for the Movie Maker and Shotcut desktop applications we were using regularly for Viktor's channel so far. Only a couple of features were missing for this amazing app to become a worthy rival, even for software with the suffix "pro" in their titles.

The smartphone applications we were testing were all Android editions, but I am sure for most of them, if not all of them, they could be found within the other two major operating systems as well. We started first with apps designed for the outdoors. For this occasion, we chose "GPS Compass Navigator", "Last Survivors", and "CycleDroid". Like Viktor said in the video, the first two could become handy if the apocalypse strikes, especially the second one, which is one great offline database of survival skills. For the GPS compass, it might not be really useful in such an event as it requires operational GPS satellites, but it was one of the best compass-related apps with maps in overlay included, which is ideal for camping.


CycleDroid is one of those few apps that we are using on a regular basis. It is basically tracking you while riding a bike and saving database entries of all cycling details, including maps. The biking map files are using recognizable formats and could be easily imported into Google Maps, for example. Sometimes it could be extremely fun—like in the above screenshot from the app, one of our cycling trips in the past accidentally painted a "sitting bear" shape on the map. We probably couldn't do it in such detail if we tried painting with streets on purpose.

The next three apps from the above screenshots belong to scientific experiments you could do with your smartphone. Perhaps the most interesting is the one in the middle—the app that can play a continuous beep by choosing frequency and amplitude. In our case, 1400 Hz was able to put out the flame of a candle! Of course, peeking into the microworld is always fun, and the first app on the list was able to take images from an external camera, in this case a digital microscope equipped with a powerful LED light. If you want to learn more about it, hop to Smart Microscope story from an earlier post or the Digital Microscope video from Viktor's channel.


Surely, the biggest power from the smartphone is the global network, the internet coming either from the mobile network or wireless receiver. However, we are taking it too much for granted, and even our smartphones can't operate in full capacity without the mighty internet today. Smartphones are able to communicate even without it just by using their network parts. Just like 'Walkie-Talkie' from the previous century, by using extraordinary apps like "Walkietooth", "Offline Chat", or "FireChat", we can pair two or more smartphones into a private small wireless mesh network and use it in the wireless range. The video shows how to do it in much greater detail.

For the next section, we are going outdoors again with two amazing games. "Street Hunt" and "Pokémon GO" are great representatives in the mobile gaming industry. While you probably know a bit or two about catching Pokémon in your favorite parks, hunting a secret location is also extremely fun and yet as simple as one such app can be. Simply put, it chooses a nearby location from Google Maps, and your task is to hunt it down. If you want to play it with friends, unlike "Pokémon GO", there are no rules but those you create yourselves.


The last section and final two apps belong to the educational realm. I left these two for the end simply because I liked them the most. I have to admit that I learned about "iNaturalist" while I was researching the apps for this collab. This is sort of a social network that helps with identifying species. The idea is simple—just photograph an unfamiliar plant, insect, or animal, send it to the app and an automated algorithm, and people will identify it for you. Last summer, one strange bird landed on the high branch of our birch tree. Viktor and I took the photo, and to test it, we uploaded it to iNaturalist for identification. Only a couple of hours later, we got three matching recognitions. Common Wood-Pigeon. 100% correct. Amazing!

The last, but not the least, comes "Star Chart". The app that uses all the orientation sensors from the smartphone to identify its position in 3D space and, with the addition of GPS coordinates, creates an augmented reality view toward the stars and all the visible and invisible stellar objects known to man. If you own a small educational telescope, you need to know where to point it. It served me well before when I wanted to show Viktor's friends Jupiter's moons, the most famous constellations and stars, Mars' redness, and Saturn's rings, but even without the scope, its educational value is priceless.


At the very end of the story about extraordinary apps we found exciting, useful, or just fun, I am enclosing the links for all the apps from the post and video. Hopefully you will find a home for some of them on your smartphone as well, or at least inspiration to search for more.

Retro Games

I am not absolutely sure that 'Retro Games' is the correct title here; after all, in the realm of video games, what is today ultra-modern and state-of-the-art within the current level of GPUs and gaming consoles, literally tomorrow we can start considering retro. On the other side, the imagination of people in the gaming industry is never old, and some games from the past, despite obsolete graphics, will always be on the top shelf of mine. Not to mention those familiar nostalgia moments when I stumble on some vintage and familiar screen that always reminds me of some happy moments from the past.


To cut the story short, one of those vintage moments triggered the idea for Viktor's and my new blog-vlog collaboration to explore a couple of old games for his channel and this small cover story. We made an easy deal and divided tasks for me to choose the games and for him to play them in front of the camera. It was interesting enough to see how a 12-year-old reacts to the old graphics and different nature of old games compared to nowadays, not only to the superb visual effects and large screens but also to the new way of gaming, which includes an amazing 3D environment along with a networked gamer's world with other players from around the globe participating in the same game in real time.

Surprisingly, he liked almost all of the 12 games I chose for the event and even installed one of them for later entertainment. The selection was not easy; there were tons of games to choose from various consoles and home computers from the 20th century, and it was hard not to be subjective. However, it was not possible to avoid some of the classics, so in the first group I chose games that are considered to be the first commercial games invented and put into production, including "Spacewar!" and "Computer Space", which originated from the DEC PDP-1 showpiece application and transferred to the first mall game console ever in 1971. It triggered a new industry race, and the very next year came PONG, the second extremely popular game that soon after occupied first home consoles as well. I also had one in the late seventies when I was even younger than Viktor today, and it was spectacular, with almost outworldly experience every time I plugged it on and connected to our old CRT television set!


The following group of unavoidable games were certainly real classics. Games that everybody was familiar with and games that still, even though not played with like before, experience media exposure, especially in movies, YouTube, and TV shows. The three games I chose were Pac-Man, Donkey Kong, and Super Mario Bros. At the end of the century, you could find them everywhere: malls and game shops, home consoles, and personal computers. Now, they live their second life in browser emulators and smartphone apps. They are not super popular, but they are still here with all of their successors and game-alike applications.

Somehow, at the same time these classics achieved the medal of popularity, home computers replaced game machines and playground shops, and I chose three of those with three game representatives that were very popular in their time. Europe's number one home computer came from Sir Clive Sinclair Labs, and his ZX Spectrum won people's hearts almost instantly. Mine too. This was my first home computer, I already wrote about on the blog, and of all the games I owned on audiotapes, perhaps the most memorable was "Jumping Jack", which Viktor liked a lot. During my high school and early university days, the CPU Z80 was the one I wrote my first machine-assembly code for, including an emulator for assembly language. Great days they were. But to conclude with this block of games, I also included "Mission: Impossible" from the equally popular Commodore 64 and "Prince of Persia" from the first PCs and their DOS environment.



The remaining three games from Viktor's video were also unavoidable: 'Space Invaders' and "Galaga" for their representative, "Tetris" for the choice of the most popular game from the first-hand consoles, and of course Atari 2600's E.T. to represent the officially worst game ever. I had to stop there; otherwise, the YouTube video would be too long, and even with these twelve, it broke the 30-minute limit I had in mind. Even though it's long, it goes without saying that I warmly recommend watching the embedded video. If you belong to the old school like me or the new one like Viktor, this story has the potential to bring your old memories back to the surface or trigger a perspective of how games looked back then in the beginning, and I promise you if you follow some of the included links to their browser emulators, the gamer's joy will emerge, if not once again, then only for a brief moment of guaranteed entertainment.
