Study checklist for a budding data scientist

April 3, 2023
Study
I recently met someone who wants to learn data science - just like I did years ago! This blog post is for you, dear future data scientist. When I look back at my data science career, I had no problem finding all the learning resources I might need freely accessible on the internet. The problem was actually the opposite - every blog, book, tutorial or tool tried to look like the most important thing in the universe that you definitely need to know. The hardest thing was to correctly prioritize all the topics. So to help you I came up with this list of topics a budding data scientist should learn. Read more

Neural networks vs Conway's Game of Life

September 23, 2020
Neural
Both neural networks and Conway's Game of Life are instant buzzwords, but combining them, that's really stupid. How stupid? Consider that the weights of the neural network that plays the game can be easily set by hand (as we will see). No amount of stupidness should stop us from doing something interesting though. Who knows, maybe we will learn something new? Read more

Pink is for girls!

Pink
"Great shirt/jacket/climbing shoes, but it comes only in pink!" That's what a complaint of an outdoors woman in an outdoor shop could sound like. Let's face it: gender stereotypes still hold our society firmly in their grasp. Even the toughest women, with climbs so hard that they put to shame many a man, can't easily avoid pink outdoor clothes, even if they would like to. Supply is simply limited. Or maybe not? Read more

What is the average mass of everything?

What

This is one of those wonderfully stupid questions that makes no sense at first glance, but you learn a lot when you think about it for a while. So what does this question even mean? Well, average mass is computed the same way every time: you sum masses of all things in a given category and then divide it by their count. For example average American weighs \(80 \mathrm{ kg}\) and average pineapple around \(2 \mathrm{ kg}\). The average mass of both pineapples and Americans together is approximately \(3,5 \mathrm{ kg}\) (there is simply much more pineapples than Americans). Ok, but we are not interested in some subsets like these, we want the average mass of EVERYTHING! Galaxies, planets, penguins, atoms, quarks! How much will that be?

Hello world!

August 4, 2016

Hello world! This is my first post at this blog. Over time I will be posting here various comments and articles about travel, science or anything that strikes my fancy at the moment. Some posts will be in english, some in slovak, hopefully most will be in both translations.
