colleges good for sciences and maths

I’m coming from London and need suggestions for universities good for maths and sciences similar to Claremont McKenna and swaftmore?

Since you mentioned two LACs, note that colleges such as Harvey Mudd, Haverford, Hamilton, Bowdoin, Carleton, Grinnell, Bryn Mawr and Reed appear in a Princeton Review sampling “Great Colleges for Mathematics Majors.” Also note that, from the Claremont consortium, a Pomona graduate won the Apker (for undergraduate research in physics) last year.
