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.

I’m worried about your heart...

I’m worried about your heart murmur,” the doc told Jack. “I’ve always had a heart murmur,” Jack protested. “Yeah,” replied the doc, “but now the murmur has started humming.” “That doesn’t sound good!” Jack was getting worried now. “It’s worse than you think,” the doc said. “It’s humming ‘Nearer My God to Thee.’”
