Re: Re 1035

An imbalance of one Cadbury egg's sugar's worth of energy is enough to cause you to put on about 9 grams of mass. That's fine on a one-time basis, but if you do it every day you gain >3 kg per year.

Re: No more pennies, at least in Canada

If we get rid of the penny we should also insist that retail establishments set their prices in 10 cent increments (unless the item is cheaper than 10 cents, maybe). Not only does that get rid of rounding issues, it also changes the annoying $X.99 prices to either $X.90 or $X+1.00.

Yes, the binomial theorem holds over every field, because the proof is purely combinatorial: to get a term ajbn-j from (a+b)n, you have to choose j terms from which to get the a, which can be done in (n choose j) ways.

Yeah, I think this is due to the sagging of the zip line. Friction is (roughly) proportional to mass, so that sliding objects descend an inclined plane at roughly the same speed regardless of mass.
