Fun Friday – COFFEE Edition!

“A mathematician is a machine for turning coffee into theorems”  Alfréd Rényi

Coffee, the greatest addiction ever, has been making the news recently.  Join me for a run-down of this greatest of the warm liquids:

1) How Coffee Affects Your Brain – PhD Comics

PhD Comics - How Coffee Affects Your Brain

PhD Comics – How Coffee Affects Your Brain

Short answer: very nicely, thanks.


2) This is your brain on coffee – NYT. From the story:

In one large-scale epidemiological study from last year, researchers primarily at the National Cancer Institute parsed health information from more than 400,000 volunteers, ages 50 to 71, who were free of major diseases at the study’s start in 1995. By 2008, more than 50,000 of the participants had died. But men who reported drinking two or three cups of coffee a day were 10 percent less likely to have died than those who didn’t drink coffee, while women drinking the same amount had 13 percent less risk of dying during the study. It’s not clear exactly what coffee had to do with their longevity, but the correlation is striking.

Apparently coffee makes life worth living.


3) Correlation, causation, and a suicidal link with coffee – Improbable Research.  The highly improbable take on the above story:

This is one of the few reports to explicitly state that coffee seems to cause (“Drinking several cups of coffee daily appears to reduce”) a life-or-death effect in people who drink it. In so doing, this report may be a watershed (and/or coffeeshed) in the history of biomedical science, and in the field of biological psychiatry….
BONUS: The report also says, a few paragraphs later, “In spite of the findings, the authors do not recommend that depressed adults increase caffeine consumption…”

The obligatory insight from XKCD belongs here.


4)  We have the benefits from coffee, so what about the cost?  Well, DataGenetics has you covered.  Here you can calculate the cost of coffee (or any regular purchase) with surprising sophistication.  Of course, if you deduct the costs of premature suicide and lethargy then coffee always works out to be a surprising bargain.

Stay caffeinated, my friends.

Time for another Fun Friday!  Here’s my list of stuff too good to throw away but not good enough to warrant its own post:

1)  Need a break from grueling research/summer classes/debugging dodgy code/perusing the course catalog to optimize your Fall schedule/simulating DoTA line-ups/or taking victory laps around the lab?  Play a few rounds of arXiv vs. snarXiv!

snarxivThe arXiv is a free repository of physics, math, and computer science papers.  This is an online manifestation of the traditions of the “pre-print”, instead of waiting for your paper to be published you sent around early copies to your colleagues at other institutions.  Now anyone can upload anything to the arXiv, including legitimate science from world experts, outlandish speculation, and gibberish.  Following up on the Sokal affair and other attempts to get randomly generated papers published, the snarXiv takes an ever-evolving list of buzzwords in a context-free grammar, and then lets you guess which title is actually real.  As you can see, my ability to pick the real paper is only slightly better than a monkey.

Fun snarXiv facts:

  1. The two fakest-sounding real papers are “Highlights of the Theory” and “Heterotic on Half-flat“.
  2. My favorite selections from the list of fake-sounding papers are “Charging Black Saturn” and “Baby steps beyond rainbow-ladder“.
  3. The average over 750,000 guesses is 59% correct, so (mostly) real science apparently sounds (mostly) like gobbledy-gook.
  4. The suggested uses for the snarXiv are:
  • If you’re a grad­u­ate stu­dent, gloomily read through the abstracts, think­ing to your­self that you don’t under­stand papers on the real arXiv any better.
  • If you’re a post-doc, reload until you find some­thing to work on.
  • If you’re a pro­fes­sor, get really excited when a paper claims to solve the hier­ar­chy prob­lem, the lit­tle hier­ar­chy prob­lem, the mu prob­lem, and the con­fine­ment prob­lem. Then expe­ri­ence pro­found disappointment.
  • If you’re a famous physi­cist, keep reload­ing until you see your name on some­thing, then claim credit for it.


2)  From the world of engineering (which, as of 1996, is no longer boring), AeroVelo wins the Human Powered Helicopter Competition from the American Helicopter association.  The flight must be longer than 60 seconds, higher than 3 meters, and stay within a 10×10 meter box.  Watch the really, really cool video here.

3)  Fox News reports that Neil deGrasse Tyson will host another follow-up to Carl Sagan’s groundbreaking documentary 33 years ago.  Watch the trailer here.

COSMOS: A Spacetime Odyssey

I really like the backstory from geek-movie-critic Movie Bob:

Fox Television gave Seth MacFarlane a big leeway for “whatever he wanted to do” in exchange for keeping ratings-juggernaut “Family Guy” on the air. He decided to spend that clout on two passion projects. One wasn’t too surprising: A new version of “The Flintstones,” which is still pending. The other? “COSMOS,” a 13-part science documentary – a sequel to the legendary Carl Sagan series of the same name – hosted by Neil DeGrasse Tyson.

Yes. The creator of “Family Guy” is going to run a science documentary on a major network because he can.


4)  And the excellence in science journalism for outstanding headline goes to: “EU boffins in plan for ‘more nutritious’ horsemeat ice cream: ‘Disused’ animal products ideal for sick, elderly”


5) Finally, because science is awesome, here’s how we intend to build the largest digital camera in the world and launch it into space:



Happy Fun Friday!
