Betting with flat Earthers - Alfred Russel Wallace

Alfred Russel Wallace has always been a favorite historical figure of TPP's.  He independently arrived at the idea of natural selection, much to Charles Darwin's dismay. Here is a link to an episode in his life that teaches an interesting lesson about science. Wallace took up a wager to anyone who could prove the Earth wasn't flat. Wallace's approach was quite interesting in that it offered direct observational evidence of the Earth's curvature, but he still "lost" the wager. This is a very well-written, brief account of that interaction by Dana Hunter of Rosetta Stones.
Addendum: Should have waited just 5 minutes to post this blog.  Here's a review of a book about the history the FLAT EARTH for those of you who never looked into this before.

Flat Earthers & debating creationists

Here's a link to a nice little historical video about flat-earthers of the 1800s and attempts to rationally, scientifically demonstrate that the Earth was a globe.  Part of this episode involved Alfred Russel Wallace, he of natural selection fame (or not, if you've never heard of him), and an simple, but elegant demonstration of the Earth's curvature.  Using a straight, "flat" canal, Wallace put poles on bridges each measured to a precise height above the water.  Then backing off to the next bridge, he set up a telescope at the same height, leveled it, and observed the poles. Although all were the same height above the water, the top of each successively more distant pole was below the top of the previous pole, as predicted, and the only conclusion that could be reached is that the "flat" canal was on a curved surface.  Of course it's the only conclusion a rational person could reach, and Wallace's demonstration settled nothing and led to Wallace's severe harrassment by his adversary.  The video concludes that there is nothing to be gained by debating or trying to reason or demonstrate science to people dedicated to creationism either.  It's a nice video.

Durian - Love it or leave it?

Experienced travelers in SE Asia would know what this sign means.  No Durian!  It would be displayed right outside your hotel along with similar no smoking, no pets, no solicitations, etc.  The only thing remotely close to this was seen in a classy motel in far upstate New York that had a sign in the bathroom that said: No Fish Cleaning In The Bathtub.  This is the only fruit TPP has known to ever be banned from buildings.  It's true, when ripe this hard, spiny rugby-sized fruit can smell something like an open sewer.  It isn't pleasant.  Yet in Thailand this fruit is a much beloved and favorite food that fetches a considerable price when of high quality.  Westerners usually have a very negative reaction like the weird food guy (Andrew Zimmeren) gagging on durian.  We laughed because it takes a lot to make that guy gag, but his reaction seemed extreme based on our experiences.  What you actually eat is a creamy colored, custardy textured aril that surrounds the seeds inside this very protective fruit.  The first record by a westerner of durian comes from no less than Darwin's younger counterpart, Alfred Russel Wallace, "To eat durian is a new sensation worth a voyage to the East to experience."  Now to be fair, he didn't say he liked it, although he did say it was worth the trip in a day and age when it took months, and it would be a new sensation.  Far from the love it or leave it extremes, there is a broad middle ground where TPP resides.  Both Phactors have had durian on more than one occasion, and our reaction is similar, it's nothing vile, nothing special; we ate enough to be polite.  Thai acquaintences snarfed up the rest.  It's rich, sort of creamy or soft cheesy in texture and taste, but rather bland, no tartness or normal friutiness at all.  We can't figure out the big deal Thai make of it, nor can we understand the negative reaction of so many people.  Durian ice cream is OK, the sweetening helps.  Only once in the continental USA have we found durian (frozen) for sale (Jungle Jim's, Cincinnati, Ohio); who knows how that is, but it was too expensive for a trial.  So for what it's worth, durian has been ticked off our bucket list.  If you've given it a try, tell us what you think.  Report on any other exotic plant foods too.     

Alfred Russel Wallace online

Each year for Darwin's Birthday party, TPP puts out his Darwin library for students to peruse, and Alfred Russel Wallace's Malay Archipelago is put out too.  The Malay Archipelago is Wallace's "Origin" and it is a worthwhile read.  Wallace is a curiosity to my students, and most of them have never heard of Wallace showing just how badly the historical aspects of science are being neglected these days.  Well, good news, everyone!  All of Wallace's publications are now online and available for free.  Such a deal!
