In existographies, Erwin Schrodinger (68 BE-6 AE) (1887-1961 ACM) (IQ:190|#26) (RGM:158|1,350+) (PR:704|65AE / physicist:20) (Becker 160:44|5L) (Simmons 100:18) (FET:11) (GPE:7) (CR:229) (LH:10) (TL:244|#33) was an Austrian physicist and philosopher, noted for []

Overview

In Feb 1943, Schrodinger, in his What is Life? The Physicist's approach to the Subject: with an Epilogue on Determinism and Free Will, a laymanized talk given at Trinity College, Dublin, stated that “life” is anything that “feeds on negative entropy”, but later recanted this, following attack from fellow physicists, stating that had he been speaking to a non-laymanized audience, he would have “turned the discussion to free energy”.[1]

Quotes | On

The following are quotes on Schrodinger:

“I have previously warned against an over interpretation of entropy as a measure of disorder, and I stress that caution again. To be sure, an animal definitely seems more ordered than the sum of its atoms, loosely distributed, and it does probably have a lower entropy. But then, what is the entropy of an animal (see: entropy of a mouse)? Or let us ask the easier question: what is the entropy of a molecule like hemoglobin, one of the simpler proteins with only about 500 amino acids? Maybe, molecular biologists can come up with the answer; If so, I do not know about it. But I do know that surely it must be a case of simplism when Schrodinger says that animals maintain their highly ordered state, because they eat highly ordered food. Indeed, before the animal body makes use of the food and anyway, and sets about to create order, it breaks the food down too much less ordered fragments than those which it ingests.”
