Secrets of Successful Varmint Calling, by Johnny Stewart, was released in 1967. I could only find a brief clip from it, but I pasted an article below with some more tips on varmint calling.
Here in Phoenix you don't need any special trick to find varmints (aka coyotes). Just go for a walk in the early morning and you're bound to see one.
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.
Physicist Cristjo Cristofv claimed that his cocker spaniel, Bijou, could not only detect nuclear fallout but also "changes in the atmospheric electrical field" caused by nuclear explosions halfway around the world.
Certainly a dog like that would be worth at least $10 million. Or so he claimed when the dog died as a result of a bad reaction to medicine given to it by a vet.
Cristofv eventually dropped his lawsuit against the vet due to unexplained "security reasons."
In the 1960s, Japan experimented with two ways of improving road safety.
First, it required that new drivers obtain a "sanity clearance" from a doctor. This was supposed to keep psychotic motorists off the road.
Second, it urged pedestrians to either raise a hand or wave a yellow flag to indicate to drivers that they wanted to cross the road.
Both efforts failed and were quickly scrapped.
The "sanity clearance" was too easy to obtain and people disliked the expense. (Imagine flunking your driving test because you failed a sanity clearance!)
The hand-raising promotion actually increased pedestrian deaths. Apparently pedestrians seemed to believe that, as long as they raised their hand, they had "permission to ignore all traffic rules and boldly march out in to the middle of the road whenever they felt like it."
July 1966: The mathematician Mervyn Stone published an article in the journal Nature that analyzed "the optimal speed and posture to adopt when caught without protection in a rain shower."
The article itself is mostly gobbledygook to me, but apparently he concluded that if the rain is coming from behind you then "walk forward leaning backwards." While if you're walking into the rain then "lower the head and walk as fast as possible."
