I am in love with this comment and want to have its babies:
pi appears as a constant in many formula of physics. General relativity says that it isn’t constant. Is it the origin of the pi particle, aka pion?
A curmudgeonly literalist might, when faced with a question such as this, harrumph a simple “No.” A more loquacious sort might explain that general relativity does not say that π is not a contstant. Pi is not a parameter of physics like the fine-structure constant, whi ...read more
In the the 19th century the Democratic party, rooted in large part among Southern planters who were dependent on exports of commodities and imports of finished goods, was the party of free trade. The northern Whigs, and later the Republicans, were the party of tariffs.

That did not surprise me, South Asians are very religious. In particular, group religious identity matters a great deal to people whose origins are in Indian and Islamic ci ...read more
How do you know whether a scientific idea is a good one or not?
The only sure way is to study it in detail and know all the technical ins and outs. But good ideas and bad ideas behave differently over time, and this can provide clues as to which ones are solid; useful if you’re a non-expert trying to evaluate a field, or a junior researcher looking for a career.
Today’s ideas are the basis for tomorrow’s experiments. A good idea will lead to experiments which provide interestin ...read more
Independence Day has one of my most favorite hero duos of all time: Will Smith and Jeff Goldblum. Brawn and brains, flyboy and nerd, working together to take out the baddies. It all comes down to one flash of insight on behalf of a drunk Goldblum after being chastised by his father. Cliché eureka! moments like Goldblum’s realization that he can give the mothership a “cold” are great until you realize one thing: if Goldblum hadn’t been as smart as he was, the movie ...read more
