Max Rubner

Died 27 Apr 1932 at age 77 (born 2 Jun 1854).Physiologist who showed the available energy content of food was the same whether the material was consumed organically or merely burned (1894). He determined that no single type of food produced energy, but that the body variously made ready use of carbohydrates, fats and proteins. In 1883, he used geometry to compare metabolic rates of animals of different sizes. Thus, if an animal is N times taller than another, it has surface area N2 greater and mass N3 greater. Thus total metabolic rate (dependent on heat loss over surface area, N2), would be proportional to M2/3. Specific metabolic rate (the energy burnt M2/3, per unit of mass, M) would be proportional to M1/3. It took 50 years before this simple explanation was improved.

A man was walking along a California beach and stumbled across an old lamp. He picked it up and rubbed it and out popped a genie. The genie said, "OK. You released me from the lamp, blah blah blah. This is the fourth time this month and I'm getting a little sick of these wishes so you can forget about three. You only get one wish!" The man sat and thought about it for a while and said, "I've always wanted to go to Hawaii but I'm scared to fly and I get very seasick. Could you build me a bridge to Hawaii so I can drive over there to visit?" The genie laughed and said, "That's impossible. Think of the logistics of that! How would the supports ever reach the bottom of the Pacific? Think of how much concrete...how much steel!! No, think of another wish."

The man said OK and tried to think of a really good wish. Finally, he said, "I've been married and divorced four times. My wives always said that I don't care and that I'm insensitive. So, I wish that I could understand women.... know how they feel inside and what they're thinking when they give me the silent treatment.... know why they're crying, know what they really want when they say 'nothing'.... know how to make them truly happy...."

The genie asked, "Do you want that bridge two lanes or four?"
