The effect of humming on vision

A Dec 1967 article ("Effect of humming on vision") by William Rushton in the journal Nature reported that:

Humming causes the eye to vibrate and this can produce a strobo-scopic effect when a rotating black and white strobe disk is viewed in non-fluctuating light.

I'm sure that's interesting, but it's a response to Rushton's article published four months later that I find more interesting. A former member of the Air Training Corps described how it was possible, by humming (or rather, "purring"), to make your head vibrate such that, when looking at a spinning propeller, the propeller would seem to stop in mid-air. By increasing or decreasing the intensity of humming/purring, one could then determine in which direction the propeller was rotating.

I haven't tested this out to see if it works, but if any of you do have a chance to test it out, please report back with your results.

Teflon as a weight-loss aid

A 2016 article in the Journal of Diabetes Science and Technology ("Polytetrafluoroethylene Ingestion as a Way to Increase Food Volume and Hence Satiety Without Increasing Calorie Content") proposed using Teflon as a weight-loss aid. The idea was to add powdered Teflon to food in order to bulk up the food's volume without adding calories. From the article:

PTFE, a plastic commonly known as Teflon®, can be used to supplement volume in the diet by mixing the raw material (virgin PTFE powder) into food. Because PTFE is heat resistant, its mixing into food can take place before or after cooking. PTFE is soft and contributes no flavor (evident by its use in tongue piercings) and hence does not detract from the eating experience. It is also resistant to the strongest acids (PTFE containers are used industrially for storing acids) and therefore will not be degraded by stomach acid. It is extremely inert (widely considered to be the most inert material known) so it will not react within the body. It has a low coefficient of friction so that it will not scratch the lining of the gastrointestinal (GI) tract during transport. Because of its chemical and physical properties and long history of use and contact with humans, PTFE is widely considered a very safe material. It is extensively used in medical devices (for instance, a large portion of the artificial blood vessel grafts that have been successfully implanted into people for decades are made from pure PTFE). For these reasons, PTFE is an ideal material for use as a nonmetabolized food volume bulking agent.

Maybe they're right about the harmless effects of ingesting Teflon, but it sure would be an uphill battle to convince the public of this given the widespread concern about ingesting Teflon from scratched pans. The manufacturer of Teflon briefly addresses this concern on the Teflon.com website:

Myth: I'm still not convinced that particles of nonstick coating won't come off during cooking and get into my food.

Fact: Particles from Teflon™ nonstick coatings are not harmful, even if ingested.

Neutron Radiation Wall

Physicist Samuel T. Cohen is credited with inventing the neutron bomb — a nuclear weapon designed to minimize blast damage but maximize the release of radiation, so that it would kill people but preserve infrastructure.

Cohen later came up with the idea of a neutron radiation wall. This would be a wall of ionizing radiation that would kill anyone who passed through it. He suggested that Israel could build a neutron radiation wall along its border to protect itself from invasion.

He described how this wall would work in a March 1984 article in Reason magazine:

What I am suggesting is the construction of a border barrier whose most effective component is an extremely intense field of nuclear radiation (produced by the operation of underground nuclear reactors), sharply confined to the barrier zone, which practically guarantees the death of anyone attempting to breach the barrier...

Briefly, this is how such a barrier scheme would work:

During peacetime, the reactors (employed underground, for protection and safety) are operated on a continual basis, as are our power reactors. The neutrons produced by the fission reactions escape into a solution containing an element that, upon absorbing the neutrons, becomes highly radioactive and emits gamma rays (very high energy X-rays) at extremely high intensity. The radioactive solution is then passed into a series of pipes running along the barrier length in conjunction with conventional obstacle components—mines, Dragon's Teeth, tank traps, barbed wire, etc. To the rear of the pipes and obstacle belts is a system of conventional defensive fortifications. (The obstacles, the firepower from the fortifications, and tactical air power all serve to impede the rate of advance of the attacker, increasing the attacker's exposure to the gamma radiation. Vice versa, by quickly incapacitating the attacker, the radiation serves to make it difficult, or even impossible, for the attacker to remove the obstacles and assault the fortifications.) The width of the entire defensive system need be no more than a few miles.

The gamma ray field in the immediate vicinity of the obstacle zone readily can be sufficiently intense that several minutes' exposure will produce incapacitation and ultimately death. However, at a distance of, say, 1,000 yards from the pipes, the radiation intensity is so reduced that people are perfectly safe. In fact, a person could stand all day at this distance without putting himself in jeopardy.

Miss General Electric

In 2017, Alex reported on "Miss Food Freezer," who also held the title of "Miss General Electric." I thought I'd try to find other winners of the latter title. But references are few and far between.

The earliest citation is 1925; the latest, 1968.

I am not sure about "Miss General Electric Torch" being the same honor.
