To the Editor:

In "Learning Science vs. Doing Science" (Commentary, Sept. 2, 2009), Jonathan Osborne writes, “No school student is going to be able to seriously critique … the conservation of matter.” He perhaps meant to say “the conservation of matter and energy.” By itself, matter is not conserved, and neither is energy. Only together are they conserved; think E=mc2.
