You’ve probably ever observed snowflakes. Even with the naked eye you can notice that none of them ever repeats another. In one cubic meter of snow there are approximately 350 million snowflakes, and each of them is unique. How’s that possible? To answer that question let’s consider the physics of snowflake formation. It’s interesting, that you can not have a pentagonal or heptagonal snowflake, they all have strictly hexagonal shape. (more…)
Wait do you hear that? Is that Ho ho ho from Santa? (or from the teacher setting your finals?) Anyway, you’re probably decorating your dorm right now or taking a shopping walk in anticipation of Christmas.

Some science lovers cannot go without science even on holidays and thus yield sometimes strange, or even crazy ideas and hand-made implementations. We don’t recommend you to construct the foregoing stuff at home, as without understanding of physics and proper safety arrangements this could turn into troubles. If you are not a physics lover, proceed to other ideas for Christmas trees in this article. So look! (more…)
Do you know who are bulls and bears? Of course, this is not about zoology 🙂 Speaking of economics and financial markets, bulls and bears – these personages have become classics – represent the two major market forces, buyers and sellers.

When Christmas trucks appear on silver screen letting us know that “Holidays are coming”, we hurry outside to play snowballs and buy gifts since the most cheerful and joyous time of the year has officially started and nothing can stop us.
