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.

Gallery Sale

An artist asked the gallery owner if there had been any interest in her paintings that were on display.
"Well, I have good news and bad news," the owner responded. "The good news is that a gentleman noticed your work and wondered if it would appreciate in value after your death. I told him it would and he bought all 10 of your paintings."
"That's wonderful," the artist exclaimed. "What's the bad news?"
"The gentleman was your doctor."
