I am coming closer to finishing my undergraduate studies, and thus, I need to write a bachelor project on a certain topic. There are millions of topics, and fields to choose from, and I simply don't know what to choose. I did some thinking, and research, and realized that the most feasible area...

Hi folks, in some previous years, I think it was a bit easier (e.g., gravitational waves), but what is your guess for this year: who will / who should win a physics Nobel medal 2019? I'm also more interested in the actual research than in the individuals, so if you don't want to pin it to a...

Centrifuges have long been viewed as the means to provide artificial gravity in the zero-g of deep space. Space colony structures like the O'Neill cylinder and the Stanford torus. Centrifuges could also work their magic on the surfaces of low-gravity planets. Conical or paraboloidal shaped...

Dear All, I am a second year Natural Sciences (the course incorporating the Physics courses) student at the University of Cambridge. I definitely want to specialize in Theoretical Physics next year, but the years spent at University, and the time in the vacations between terms, seems so long...
