Did anyone in the Toronto area manage to get a glimpse of the ISS this morning? It was to be in the southern sky about 6:30am for 2 minutes. Daughter and I got up and went out to find it but didn't! Where can I find out about other sighting times?
Thanks all.

Just saw the second half of a documentary on Einstein on PBS. They talked a lot about E=MC squared but don't recall hearing them say what the "C" represented. Really great doc that peaked my interest.!

If f(t) is the quantity in grams of a chemical produced after t minutes and g(t) is the same quantity in kilograms, then f'(t) = 1000g'(t).

Please explain to me wheter this statement is true or not.
