| Quotations for Today | |
| "Economic predictions are in principle inconsistent, because they cause agents to act in a different way from that predicted." - Oskar Morganstern, economist-mathematician who created "game theory" (born 24 Jan 1902) "When the ancients were amusing themselves by demonstrating the properties of the sections of the cone, they little thought what aid their investigations would afford the future astronomer. So the chemists, who discovered the latent heat of steam and the specific caloric of atmospheric air, could hardly be aware that from their discoveries would soon arise a theory of meteorology, explaining so many atmospheric phenomena." - James Pollard Espy, American meteorologist who explained cloud formation and growth using thermodynamics (died 24 Jan 1860) (source) "It appears ... as if the difference between sense and nonsense material were not nearly as great as one would be inclined a priori to imagine. At least I found in this case of learning by heart a few cantos from Byron's 'Don Juan' no greater range of distribution of the separate measure than in the case of a series of nonsense syllables in the learning of which an approximately equal time had been spent." (1885) - Hermann Ebbinghaus, German psychologist (born 24 Jan 1850) | |
