Not a lot of heavy Substance today, just a few links I found interesting.
First off: Do You Taste What I Taste? -- a neat little survey of the physiology of wine-tasting, from Slate. Turns out memories and associations have a tremendous effect on one's perception of flavor. As does the price of the bottle.
Second: Whales and Zeppelins! -- two megacool things that get even cooler together. If you're studying cetaceans, there's no better platform from which to do it than a cruising Zeppelin.
Armed with these interesting bits of trivia, have a good weekend.
