Struggling with General Relativity Calculations?

Thread 'Hello world!'

Hello there, and nice to meet all of you! My name is Olga, I am from Russia. I have a PhD in laser physics, and I work at the local university. I study chalcogenide lasers. I am a pure experimentalist, and I love working with my hands, et cetera, and I do math only when I have to. Sometimes I work with biologists. I do nothing exciting in research, and after my defence, I hardly can call myself a scientist because we have a lack of financial support, and most of my time I spend on teaching...
