I'm looking for a font family of san serif and sans which would look great for a scientific book design. It will be on string theory. Any suggestions would be great.

The fonts I like are:

http://usfonts.gestalten.com/t-star.html
https://ourtype.com/#/try/pro-fonts/fakt/
http://usfonts.gestalten.com/blender-pro.html

But I need to use a type with a sans serif and serif version rather than using two typefaces.
