About Me Hello! My name is Katherina. I will write short notes here from time to time. Hope they will be interesting for you. English native speakers are welcome to correct my texts to help me improve my terrible English at least to not very poor English :) I'm a scientist. I'm mostly a mathematician, but also do a little astronomy. Professional astronomy and mathematics have much more in common than it seems. The attached comic picture illustrates this fact. People can fly to other planets of our Solar system, but they cannot reach distant stars yet. Light is the fastest that is in the Universe, it flies from our Sun to the closest star Proxima Centauri more than four years. But there is good news. Astronomers can already detect other stars' planets. They call them exoplanets. Who knows, maybe we'll meet alien civilizations on some of these planets...
