Is a hotdog a sandwich?

Humans seem to be fascinated by ambiguous classifications, especially about hot dogs. Here are other answers: bit.ly/AW-hotdog, bit.ly/AW-hotdog2, bit.ly/AW-hotdog3. The Oxford English Dictionary definitions of sandwich (bit.ly/OED-sandwich) imply that common usage permits broader definitions when those are accompanied by a modifier: e.g., submarine sandwich, open-faced sandwich. Maybe a hot dog is a sandwich when you say, “hot dog sandwich.” While you ponder, listen to this 1949 Louis Prima Band recording of “Yes, We Have no Bananas”; at the 2:40 mark you’ll hear how they said it in New Yawk. bit.ly/YesNoBananas

According to Pantone, the semi-official gods of color, there are 14 different colors of pear. Check them out here: bit.ly/PearColor. However, there is one color Pantone missed…

Do you know the muffin man?

Do you know the muffin man?
Do you know the muffin man?

Not personally, no. But I do know a wall in downtown Boston who is second cousins with a wall on Drury Lane. So that’s pretty cool. I’m also an professional acquaintance with the Bodleian Library walls which hold the oldest known manuscript of The Muffin Man (circa 1820). So that’s also pretty neat.

How many holes does a straw have?

How many holes does a straw have?

You’re not the first to ask this! In fact, I answered this question in February. (http://bit.ly/strawholes) While some might think there are two holes, there are actually 2 openings for one long hole. Think about how many holes you would see if you squished that straw into a 2-dimensional disk!

Is water wet? Can fire be burned?

Is water wet? Can fire be burned?
Is water wet? Can fire be burned?

Wetness is a perception, not an objective fact, and perceptual clues for wetness are actually not so straightforward, as you can see in this physiology article: bit.ly/wetness-perception. So, is water wet? Sorta maybe. Can fire *be* burned? Though as a wall built partly of flammable material I wish fire could be burned, it can’t. Fire is just the light and heat resulting from oxidation of fuel; there is nothing in fire to oxidize, because fire itself isn’t a substance it’s a process.

Is every simply connected, close 3- manifold homeomorphic to the 3-sphere? If yes, please provide proof.

Is every simply connected, close 3- manifold liomeomorphic to the 3-sphere? If yes, please provide proof.
Is every simply connected, close 3- manifold homeomorphic to the 3-sphere? If yes, please provide proof.

Yes. Poincaré’s conjecture (formerly a Clay Mathematics Institute Millennium Prize Problem) was proved by Grigori Perelman using Richard Hamilton’s Ricci flow program and confirmed in 2006 following review (bit.ly/CMIperelsol). Read the complete proof in the Asian Journal of Mathematics (bit.ly/poincareproof).

How many holes does a straw have?

How many holes does a straw have?

A great question that can really start a huge debate! Some argue there are two holes because of both openings, some argue there are no holes at all. However, if you take the straw and squash it into a disc, you’ll see that there is actually only one hole. This question can be answered mathematically through Topology, which you can see in this Forbes article (bit.ly/strawhole) or find more information about Topology in the stacks! (QA611 .M82 2000)

Can a coll. student do anything immoral?

Can a coll. student do anything immoral?
Can a coll. student do anything immoral?

Well, yes. Students are no more immune to questionable behavior than anyone else. The real questions are “Should a student do anything immoral?” (probably not) and “How can students resist the temptation to do something immoral?” (probably many ways to do that)
