So you're saying a better understanding of nuclear reactions has not had practical implications? Just because the particle itself is 'useless' from a technological perspective doesn't imply the same is true for the accom

Sure: When hiring, you work with what's available. But as a community, it doesn't hurt trying to figure out where such ridiculously large gender imbalances come from, and if there's something that can be done about it.

If you have a gender imbalance of 27:0 that is not predicated on self-evident physiological differences, there's a cultural problem that artificially limits the pool of potential candidates. It is in a field's best interest to fix

An idealized 'dot' has zero 'volume', as does a countable number of such dots. The bulk of the real number line is made from irrational numbers, with a countable number of rational dots mixed in. If you define the '

And I'm guessing you've had more time to think about this than I have. Not necessarily - I just like to muse about big-picture problems with society from time to time. Contrasting median and mean income (a flawed measure for var

I consider socio-economic polarization an existential threat to democracy: Money buys political influence, so I would argue there's a legitimate fear of capitalist societies turning into oligarchies.

Because the graph becomes illegible, and the reference value of interest to me is not where the median vanishes, but where median and mean are equal. As I said repeatedly, if you don't like the graph, post a better one!

by cygx 8y ago
By all means, make a better graph, so I can tell you what you really meant by your choice of presentation after the fact :p

I just googled the data[1], removed the duplicate entry for 2013 from the Excel spreadsheet when the methodology changed (shoddy on my part, I know) and made a graph from it that was readable in the five minutes before I posted my comment.

Letting the y-axis start at 0 loses too much detail.

Personally, I like to check the ratio of median to mean household income as a crude measure of socio-economic polarization. It's not pretty: https://i.imgur.com/58MIBxB.png edit: here's an alternative version fo

Assuming there’s only one particle in the universe it would still have a temperature right? Not really. One (not quite universal) way to think of temperature is as a measure of average energy per degree of freedom (linear motion, rotation

In my opinion, that whole 'moving away from us faster than c' business is not really a good way to think about this: For one, we can see to a redshift of about 10, corresponding to a comoving distance of about 30Gly, and a recessi

Objects don't outright disappear: As with other event horizons, they freeze in time and become redshifted as they approach the cosmological one (they also become fainter due to an increase in proper distance). The cosmological event ho
