I was a 19th century German mathematician and astronomer. I developed a lot of math: there's my configuration, formed by two mutually inscribed tetrahedra, my transformation in number theory, my transformations in projective geometry, my function, and my inversion formula. Pretty nifty, eh? You're probably most familiar with the strip named after me, a two-dimensional surface with only one side. Who am I?

I was a 20th century physicist at Princeton and MIT. I designed apparatus for experiments in radiation and particle physics. My eponymous invention, a static electricity generator, has been superseded by other, higher energy devices. But, it is still used for demonstrations in classrooms and science museums worldwide. Who am I?

I was a 20th century German physicist. I did extensive work on radioactivity with Ernest Rutherford, and devised a formula, named after me, for the velocities of particles. I contributed to the discovery of the atomic nucleus, and participated in Germany's effort to build an atom bomb. The radiation counter I developed and steadily improved upon is still used today.
