Update on our smelling prowess

Some time ago, I wrote about a study that said that we humans could smell 390 different smells. This seemed big enough to me but as commenter ChasCPeterson pointed out, this was not the full story because that number referred to the distinct number of olfactory sensors we have that can identify specific molecules but that we can actually smell combinations of these basic smells and the number of combinations can thus be much larger.

It must have seemed like a good idea at the time

Bill Donohue, head of an outfit called the Catholic League and who is more Catholic than the pope, seems to make a good living and gains publicity by protesting loudly at anything that can be interpreted as a slight on Catholicism. He was predictably outraged (his outrage meter is always at 11) at the attempts by LGBT groups to march in the St. Patrick’s day parades in New York and Boston. When they were rebuffed, Donohue was again outraged that beer companies Sam Adams, Heineken, and Guinness withdrew their sponsorship and vowed not to drink their beer.

Harry and Hermione (Harry Potter spoiler alert!)

When I was reading the Harry Potter books, although J. K. Rowling told a good yarn and plotted her stories well, the romance between Hermione Granger and Ron Weasley never seemed to me to be plausible. It seemed like the author was trying to avoid the obvious narrative device of the leading man and leading woman getting together at the end and was going for the slightly counter-intuitive relationship. It just did not work for me. Harry’s romance and marriage to what’s-her-name was also implausible as can be seen from the fact that I can’t even recall her name (or her face from the films) and remember anything about her except that she was Ron’s sister.
