Types of Bears

A married couple was vacationing in Yosemite Park in the United States. The wife expressed her concern about camping because of bears and said she would feel more comfortable in a motel. The husband said he would like to camp outside in the woods. To calm her concerns, he suggested they talk to the park ranger to see what the likelihood of a bear encounter would be.

The ranger told them, "Well, we havewn't seen any grizzlies in this area so far this year, or black bears, for that matter."

The wife shrieked, "There are TWO types of bears out here? How can you tell the difference? Which one is more dangerous?"

The ranger replied, "Well, that's easy -- see, if the bear chases you up a tree and it comes up after you, it's a BLACK bear. If it SHAKES the tree until you fall out, it's a grizzly."

The motel room was quite nice.

Galvani's electric fluid

In 1780, Luigi Galvani recorded, "The electric fluid should be considered a means to the nervo-muscular force." He reached this conclusion from work in his laboratory in Bologna, Italy, after a series of experiments and his accidental discovery that muscles are operated by electrical stimulation of nerves. He worked diligently along these lines, but waited for eleven years before he published the results and an ingenious and simple theory. His theory was that of a nervous electric fluid, secreted by the brain, conducted by the nerves, and stored in the muscles. Though his ideas were abandoned by scientists on account of later discoveries, his work opened the way to new research in the physiology of muscle and nerve and pioneered the subject of electrophysiology.
