Editor, Letters to the Editor, NY Times copy to: Editor, Charleston Post and Courier Dear Sirs: In his article, "On a a Particle's Trail, Physicists Seek Time", (Nov. 4), James Glanz repeatedly makes an egregious error in using "weight" to mean "mass". Although this is commonly accepted usage in colloquial and commercial matters, it has no place in an article about physics. As any scientist can tell you, mass and weight are different quantities, the latter being a force. I would hope that your science writer knows that distinction. regards, James R.
