The Crocker-Henderson Odor Classification System

In the early twentieth century, odor researchers Ernest Crocker and Lloyd Henderson created a classification scheme that allowed them to number and catalog every smell in the world. Kind of like a Dewey decimal system for smells. Every different odor was assigned a four-digit code.

Their system was based on the premise that every smell is a combination of four "primary odors." So the four-digit code was created by judging and listing the relative strength of each primary odor.

Crocker would sometimes telephone Henderson and call out a number: 6443! 8257! Henderson would have to guess what it was – Old grapefruit rind? Tomato sauce? Shaving lotion? Most times, according to Crocker, Henderson would be right. They would go on "smelling binges" in the Arnold Arboretum, putting a number to each blossom.

The problem was that judging the relative strength of each primary odor in any one smell turned out to be a very subjective process. Other people struggled to replicate the numbers that Crocker and Henderson came up with. So their system was never adopted by other researchers.

The Acoustics of Miniskirts

October 1969: UCLA Professor Vern O. Knudsen assembled ten young women wearing miniskirts in a reverberation chamber and fired a blank cartridge from a pistol. He did this to prove his hypothesis that bare legs revealed by a miniskirt will reflect more sound than legs covered by a long skirt.

His hypothesis confirmed, he warned that miniskirt wearers might disturb the carefully engineered balance of sound in concert halls by reflecting more sound. He noted: "We must be acoustically thankful that they don't wear bikinis."

Oddly enough, this wasn't the first time a scientist had warned of the acoustic danger of short skirts. Back in 1929, Colgate University Professor Donald A. Laird had issued a very similar warning: "He quoted scientific reports to prove that shortening of women's skirts has added to noise by removing some sound deadening surface."

Unlikely Reasons for Murder No. 11

In 1952, a schizophrenic with an eccentric theory of physics murdered a random person.

“Have they dropped the electronic theory?” he asked her.

“I don’t know anything about it,” she replied.

Before she could say more, he fired the gun at her.

“I just wanted to kill somebody,” he told police. “I was going to shoot anybody. It was my book. They wouldn't look at my book. They wouldn't even look at it."

Peakes had done the calculus: Shooting people gets you in the papers. And if you shoot physicists because they rejected your theory, your theory gets in the papers.

The Palatibility of Tadpoles

In 1970, biologist Richard Wassersug conducted a study to determine what different kinds of tadpoles taste like. More specifically, whether some taste worse than others. He convinced 11 grad students to be his tadpole tasters.

The standardized tasting procedure included several steps. A tadpole was rinsed in fresh water. The taster placed the tadpole into his or her mouth and held it for 10-20 sec without biting into it. Then the taster bit into the tail, breaking the skin and chewed lightly for 10-20 sec. For the last 10-20 sec the taster bit firmly and fully into the body of the tadpole. The participants were directed not to swallow the tadpoles but to spit them out and to rinse their mouths out at least twice with fresh water before proceeding to the next tadpole.

The most distasteful tadpole was Bufo marinus, while the most palatable ones were Smilisca sordida and Colostethus nubicola.

This confirmed his hypothesis that the most visible tadpoles were the least palatable. Their bad taste deterred predators from eating them, whereas the better tasting tadpoles relied on concealment to avoid being eaten.

Thirty years later, Wassersug was awarded an Ig Nobel Prize for this research.

Can you speak Venusian?

In his 1972 documentary, Can You Speak Venusian?, the British astronomer Patrick Moore examined the astronomical theories of various "independent thinkers" — otherwise known as kooks. It's probably now the only footage of most of these odd folks, talking about their odd ideas. Moore released an accompanying book of the same name.

My favorite of his independent thinkers is John Bradbury and his 15-lens telescope, viewable at around the 15:30 mark. His basic idea was that if two lenses are good, then fifteen must be even better. Bradbury claimed his telescope was so powerful that it could show "the actual background casing of the universe."
