Unrelated physics devices

These two items came over the transom here within minutes of each other. Presumably there is no connection between them. ITEM A) How to Calculate Pi by Throwing Frozen Hot Dogs. ITEM B) US patent #7,147,609 B2, “Penile volumetric measuring device,” granted to Jason E. Turner of Washington, D.C. (Thanks to investigator Martin Gardiner for […]

The tastiest Ezine

Investigator Richard Wassersug writes: “I just learned that the word “ezine” has more than one meaning.” Investigator Wassersug refers to this newly published study: “Sensory Characteristics of Ezine Cheese,” Yonca Karagul-Yuceer, Muge Isleten and Cigdem Uysal-Pala, Journal of Sensory Studies, vol. 22, no. 1, February 2007. Ezine cheese is a full-fat, white pickled cheese ripened […]

Calculating the value of prostitution

There are many theories about prostitution. The theory devised by Marina Della Giusta, Maria Laura Di Tommaso and Steinar Strom is one of the few that involves partial differential equations. Sure, they could, if they wished, describe prostitution in words. But for scholars who want to explain prostitution, differential calculus may be the clearest language. […]

The Prof. Touyz clinical charts

The use of the Clinical Charts for History, Treatment Plan and Special Investigations is a guide to assist establishing a definitive diagnosis, as opposed to a presumptive diagnosis. The type of Oral Malodor, or combinations thereof, should be defined. So says the official guide to using the special charts prepared by Dr. Louis Touyz, the […]

The virtue in virtual victims

Lacking human subjects, researchers torture virtual females for science Back in the 1960s, the hot new research was Stanley Milgram’s tests on human behavior that involved subjects who thought they were administering electrical shocks to female victims for failing to answer test questions correctly. Some participants could hear their “victim” scream in response to the […]

The physics of squirrels

Automatic Squirrel-Ejecting Bird Feeder This is the bird feeder that automatically spins when a squirrel’s weight rests on the feeder, gently but firmly flinging the squirrel safely away without harm and discouraging return visits (see the Bird Feeder in action). The mechanism is sensitive enough to allow finches, chickadees, and other lightweight songbirds to feed […]
