@Wolf –
Dunno what the Wikipedia writer was on, er, referring to, but I have a Masters in psychology and am in the midst of the doctorate program and have yet to have had a use for any trig (which is good, because I didn’t know it in high school, and don’t know it now). Statistics yes, but not trig.
@Charlie –
I forgot the Rav you mentioned who earned a PhD in chemistry (I’m not going to go looking for it again), but I doubt he would say chemistry is an important topic for every single person to know.
CHILL! If HIE wants to use texting language on this forum, what’s it to you? And you people say New Yorkers are uptight…This isn’t a medical journal, there’s no problem with using “cuz”.
