Multiple choice general knowledge science & technology

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?

  2. August Ferdinand Möbius

  3. David Hilbert

Explanation

August Ferdinand Mobius was a 19th-century German mathematician and astronomer who made significant contributions to geometry and number theory. The Mobius strip is a non-orientable surface with only one side and one boundary, created by twisting a strip of paper 180 degrees and connecting the ends.
