Knowing VS Speculation

One day I'll be convinced there's a certain type of symmetry that everybody believes in, the next day I'll try to figure out the consequences if it's not, and everybody's crazy but me. But the thing that's unusual about good scientists is that while they're doing whatever they're doing, they're not so sure of themselves as others usually are. They can live with steady doubt, think "maybe it's so" and act on that, al lthe time knowing it's only "maybe." Many people find that difficult; they th...

 Spinoza's Reasoning was Childish

There's a tendency to pomposity in all this, to make it all deep and profound. My son is taking a course in philosophy, and last night we were looking at something by Spinoza--and there was teh most childish reasoning!

Here's this great Dutch phiosopher, and we're laughing at him. It's because there was no excuse for it! In that same period there was Newton...

 Science as a Quest

Pysicists are trying to find out how nature behaves; they may talks carelessly about some "utlimate particle" because that's the way nature looks at a given moment, but... Suppose people are exploring a new continent, OK? They see water coming along the ground, they've seen that before, and they call it "rivers." So they say they're exploring to find the headwaters, they go upriver, and sure enough, there they are, it's all going very well. But lo and behold, when they get up far enough they ...

 Computer Programming Brings Complex Thought to the Masses

Omni: Does that limit the number of people who can contribute, or even understand what's being done? Feynman: Or else somebody will develop a way of thinking about the problems so that we can understand them more easily. Maybe they'll just teach it earlier and earlier. You know, it's not true that what is called "abstruse" math is so difficult. Take something like computer programming, and the careful logic needed for that--the kind of thinking that mama and papa would have said was only for ...
