[@stardust]Granted, but in what we would refer to as the 25th century humans only exist as primitive hunter-gathers due to SOMEONE'S wish, the closest thing to a physicist is a shaman.  You now wear nothing but a loincloth and have multiple piercings with bone jewelry, and believe that the sun is a vengeful fire-spirit.  At least basic math and newtonian physics is still around, though, so you have some scientific knowledge still.

I wish for super powers.
