I mean Nvidia has been naming thier chips after scientists for a while now Hopper, Blackwell etc. Names are not copyrightable, you can literally create a toaster and call it Einstein. It doesn't mean you're doing anything illegal. There are some exceptions like if the name is actually used by a brand (like Tesla now) or if the person is alive/recently dead, or if you claim they are in someway endorsing your project. Like claiming "Einstein always toasted bread with the Einstein toaster!" is not okay.

The way Nvidia does it is actually super respectful and it's honestly better to use names like these instead of ULTRA PRO MAX 5x etc.
