Quantum mechanics explains how atoms, molecules, and other fundamental particles interact. Einstein's theory of general relativity, on the other hand, helps to explain how things work on a large scale. But there's a problem: these two branches of physics don't seem to fit together. While much work has been done to address this issue, it remains one of the most difficult problems in modern physics.

Arsenal on the Kyiv city metro line (Sviatoshynsko - Brovarska Line) is currently the world's deepest metro stop. It is 105.5 meters deep. Escalators transport you deep underground so that you can catch the train. Arsenal had to be 105.5 m deep because it had to bypass the Dnieper River, which rises above and surrounds Kyiv. You will ride the escalator for five minutes to reach 105.5 m deep down the station.

Vegan infants, rejoice!

When the weatherman reports a "real feel" temperature of -10 degrees outside, it may appear as if he made up the figure on the spot. Wind chill, on the other hand, is calculated using a complex equation devised by meteorologists. Wind Chill = 35.74 + 0.6215T – 35.75(V0.16) + 0.4275T(V0.16) for math nerds who want to try it at home.
