T Rex Had Strongest Bite Ever

Study: "T. rex had the strongest bite, ever".

Past studies estimated the T. rex's biting force to be as powerful as 13,400 Newtons (3,012 lbs). However, the new British study, which tested a wider range of muscles, found the biting force was more likely between 35,000 (7,868 lbs) and 57,000 Newtons (12,814 lbs) in a single rear tooth.

"That's equivalent to a medium-sized elephant sitting on you." Dr Bates told the BBC.

The human biting force is typically less than 1,000 Newtons.

Wine Tasting Fallacies

This recent Freakonomics podcast discusses how much our perception of a wine's quality is biased by our (correct or incorrect) belief about its price.

A tidbit from one of the blind taste tests:

Levitt used four decanters. Into the first decanter, he poured one of the expensive bottles of wine. The other expensive wine went into decanter number two. In the third decanter, he poured the cheap wine, which cost around $8. In the fourth decanter, he repeated one of the expensive wines...

LEVITT: The data could not have cooperated more completely with my hypothesis. So for starters the four wines received almost identical ratings on average. Although there were a wide spread among individuals, on average, tallied up, people did not prefer the expensive wines to the cheap wine.

On top of that, and this was the thing that I was hoping for and dreaming of but didn’t believe would actually come true: It turned out among individuals if you compared how differently they rated any two of the wines that they had, it turned out that by a small margin, people actually rated the same wine from the same bottle but presented in a different decanter as being the most different among the two wines.

So the two wines that were absolutely identical, when you looked at the gap between the ratings that an individual gave to those wines, the gap was bigger than they did between the other wines, which actually were different.

Fifth Amendment Protects Suspects from Having to Decrypt Hard Drives

WSJ: "Fifth Amendment Protects Suspects from Having to Decrypt Hard Drives"

From the article:

The Fifth Amendment privilege isn't triggered when the government merely compels some physical act, like unlocking a safe-deposit box, the court said. But the amendment protects testimony in which a person is forced to use "the contents of his own mind" to state a fact.

"We conclude that the decryption and production would be tantamount to testimony by Doe of his knowledge of the existence and location of potentially incriminating files; of his possession, control, and access to the encrypted portions of the drives; and of his capability to decrypt the files," wrote Judge Gerald Bard Tjoflat...

On the other hand, we have this story from a similar Colorado case: "Ruling Stands: Defendant Must Decrypt Laptop"

The Mathematical Equation That Caused the Banks to Crash

"The mathematical equation that caused the banks to crash".

I found the article informative, but the title a bit misleading. As the article notes, the problem was not the Black-Scholes equation per se, but rather how it was misused when inappropriate to circumstances. (Something true for many tools, such as guns or computers.)

Update: Reader B.E. pointed me towards this article arguing that, "Black-Scholes Didn't Cause the Financial Crash".

Update: Reader C.S. pointed me towards companion information about the Nova story, "Trillion Dollar Bet". One could reasonably infer a position somewhere between the two sources cited above.

WSJ: A Car That Tweets

"Don't Look Now: A Car That Tweets" (Wall Street Journal, 2/10/2012).

I like progress as much as the next person, but I must confessed to a mixed reaction to cars that allow you to do hands-free Twitter and Facebook at 65 mph. From the article:

Customers say they love the electronics. "I like the way it looks," said Jamie Kaye Walters, 38, a television production company executive who recently bought a 2012 Ford with the Sync system. "It's a little bit distracting, but it kind of allows me to do work while I am driving without having to look down at my phone. I can do the whole thing with voice activation."

Um, if doing your work is "distracting", maybe you shouldn't be doing it while driving...

"It was the song by John Lennon," [English teacher Steve] Schriener recalls. "I said, 'Honestly, I was born in 1957; do you think I don't know the Beatles?'

"He just said, 'I was hoping you didn't.'"
