Hi, today I am going to write about cycloids or epicycloids, I am not really sure myself because one of them are definitely “shapes” that you get by tracing a point on a rotating wheel of a bicycle lets say, but in my case, I am tracing a line that connects two points on two (or one) circle(s).

The idea actually comes from the orbital resonance of for example Earth and Venus, which can create…

The best solution to the three 3s puzzle

Hi, today I am going to write about “my own” work. Specifically the solution to the three 3s puzzle which I encountered in physics camp (where as a morning routine we solved some problems) and nobody (I guess) knew solution back then.

It goes like this: Using plus, minus, division, multiplication, square roots, exponents, brackets and factorials and three 3s, get the number 1 through 10. All…

Blue eyes: logic puzzle

Hi, about one or two weeks back, while scrolling through XKCD comics I have bumped into Blue Eyes logic puzzle, that Randall (the author of XKCD) heard in Boston from some random guy named Joel. Randall titles the puzzle as the “hardest logic puzzle”. It was not the case for me so I would title it as “most interesting (and hard) logic puzzle”. Here is why:

I wont rewrite the setup for the…

First experience with hammock

Hi,

I want to share my experience with sleeping in a hammock for the first time.

So I got hammock for my birthday among other things. After finding some cords to tie it to trees I realized that it will be best to try sleeping in it. Since it is almost November and I happen to live in northern hemisphere, it can get close to 0 degrees (no, not Fahrenheit you dummy). Luckily there seems to be…

Hi, nobody expected it and yet it happened, nobody has foreseen it and yet it was inevitable, nobody cares and yet I am here once again!

After 5 months, three seasons of Rick and Morty, 2 weeks in CERN and bunch of other stuff, I have returned to strike back with an epic post full of me talking about how I came back while wishing I will write another post after this one.

Now I feel a bit stupid,…

What does “x” and “y” even mean?

Hi, so after quite a break, I am returning with math post. It is going to be simple analytical geometry or whatever this field is called.

After teaching some people about lines, circles, circles in a hydraulic press (read: ellipse) also vectors and all sorts of shapes that you can think of[1] I bumped into a fundamental issue that my “students” missed out something important even after using it…

Is consciousness an illusion?

Hi, so apparently we have a problem. Noone knows where consciousness comes from. This is quite a big question since that is what we are, right (?) the mind.

I find this idea of consciousness very interesting, we cannot share what being mindful feels like or see that another creature is aware. We have to take it for granted from what others tell, there is no way you can tell that your friend is…

Hi, apparently, the three year anniversary was already yesterday though I thought that my first post became public on 21.3.2015, I guess I was living in a lie.

What now? I have been very lazy in the past weeks, not posting a lot. I am still planning to continue to write the blog, I have no doubt, definitely.

In the three years I:

Hi, today I will write a short post about the power of mnemonics.

Those are things that help you remember something. One that I used quite a long time ago was Saturn mnemonic. I was not sure if it was Jupiter or Saturn with rings but then I realized that the letter “S” is basically just circle disconnected and changed into the shape with a single movement. One could argue that this does help…

Hi, today I will write about a new thing that I just learned over the weekend. Since it is based on a competition again I will care not to post here too much so as to be fair and not to spoil it.

Cellular automatons, at least in my knowledge so far, are in a sense, computer colonies, comprising of tons of cells. In the simplest version, you have 1-dimensional automatons which means that the…

Hi, today I will write about societies and generally some at least partially closed groups of people that even if they seem different from each other, they share one ultimate tactic to survive.

I will start with the most common and intuitive example which is, of course, a dictatorship. For a dictator to be in reign for a long time he needs the people of the state (no ruler rules alone). Of…

Hi, today I am going to write about one of the problems that I had to solve for a physics seminar. The submissions for this series are already closed and you can look up the solutions so I know that I answered correctly to this very interesting problem.

Imagine you have two types of particles, A and B. They are radioactive, meaning they keep falling apart but in a very peculiar way, A decays…

Hi, it just so happened that it took me few weeks to finally write something. I was over the holidays on Mallorca and then I missed the last week too, oh well, today I will compare some aspects of physics and maths that I noticed and why I choose physics over math.

This is something I have realized lately during solving of physics and math problems. While math is certainly groundstone of physics…

Hi,

It’s not like science is the trend here though the blog title could be misleading for some people but yeah, today I am not going to write about Science and Rationality. Today’s topic is quite personal and it is about the music that I listen to. I can date exactly when I started to listen to what I listen to now. It happened on 20th of June 2015 when I heard the first songfrom Insomnium. This…

Hi,

Today I was going to write about the book Brave New World and happiness but just few minutes back I settled on something else so I am not even sure what will come out in the next several minutes.

As I was going through my news feed on Facebook I noticed Phil Plait posting again. It is about another black hole merger and gravitational wave detection. This happened I think four or five times…

Hi,

Coincidently just this weekend I started to read Brave New World by Aldous Huxley, because I need it for my English class. At the same time during today’s class (English conversation) we spoke about GMOs. Speaking on the topic means that I read Wikipedia page for 10-15 minutes and then I presented it in front of the class. Then we moved on to another topic and there were no comments from…

Can you find everything on the Internet?

Hi, so over the last Sunday I have spent a LOT of time doing physics. This meant mainly analyzing the problem (which was the movement of rocket through the Solar System) and then ton of writing and rewriting but in particular researching on the internet. I had real trouble sometimes and spent countless minutes search information like “energy density of RP-1” which is a rocket propellant and how…
