I personally like the idea of giving scientists' names to cards. It makes people more interested in 'who was that scientist?' and thus is popularizing science and physics.
By the way, the very fact that Entropy is considered an element in Elements shows that real-life science is mixed into Elements. Gravity and Time are also kinda real-life science things, since in a typical fantasy world filled with magic and mythological creatures, gravity is simply viewed as a constant force, that is natural and obvious to everyone (this kind of fantasy rarely goes into space, or into other places where gravity has different strength), while Time is also considered an obvious and natural constant unless some kind of magic is trying to alter it.
In Elements, at least Entropy and Gravity are seen from a more scientific point of view, not typical to fantasy. Black Holes, Supernovas, Antimatter and stuff. Of course it is mixed with fantasy (Otyughs, mutations etc.), but that's normal. Elements are not meant to be a simulation of science from real world, but rather an interesting mix of fantasy, some science-fiction, and some peculiarities from real world. And names such as Maxwell and Schrödinger fit this theme well.
By the way, it's not necessary that Maxwell and Schrödinger from Elements are the same people that wore those names in our world. Maybe Maxwell was a demon summoner? Maybe Schrödinger was some crazy cat-breeder? I remember playing The Witcher, and there was a reference to Nobel... who was a gnome that invented explosives, and then committed suicide when he realized that magi are going to use his invention for evil purposes... or something along those lines
This was a kind of Easter Egg though.
