I'm not an engineer, but this [0] appears to be at least one patent related to technology used to cool the air and economize on methanol. Perhaps someone can interpret it for a more general audience? [0] https://www.google.

I was commenting on the motivation to edit existing articles rather than posting new articles, or even just pulling the original article.

I wonder how much the stability of the URL influences this sort of editing. If traffic is coming in via a site such as reddit, a new article with a new URL might not get as much traffic as an edited version of the original article.

The continental USA hasn't been considered an empire since the 1840's, any more then the UK is considered an "English Empire". I suppose the continental USA could be invaded by Mexico or Canada, in which case one would h

Perhaps because it's HN, the discussion is focused on SF and NY. But it's SoCal and Florida that surprised me.

You're correct that specific technologies can drive a small company (Heptares in the UK [0] -- springs to mind). Mostly, though they are business-to-business, rather than the typical view of startups. [0] http://www.heptares.

Enzyme isolation might be tricky, and unpredictable, but the equipment isn't particularly expensive. You can buy top-of the range equipment from various suppliers, or literally build it yourself. You could build a system like ÄKTA [0]

While I agree with you with health-related biotech, not all biotech is in this area. There are quite a number of industrial uses for biotech that would not require the extensive testing and validation required for drugs. Examples might be

As you say, Bayesian statistics is not of much use when there is no prior information as to the frequency of certain events. Once any amount of such information is available, then it comes into play.

You're correct that the article failed to point out that the increase in CO2 was unambiguously man made. Now, is the temperature increase caused by the increase in CO2 - likely so since the correlation is so close. Have they exhaustive

by pcrh 11y ago
The rise in CO2 is man made, as determined by the isotopes of carbon present in the atmosphere. Fossil fuels contain no C14, and the decrease in the ratio of C14 to C12 in the atmosphere since 1800 corresponds to the rise in fossil fuel co

Yes, there are much better software suites than generic ones for drawing and manipulating molecules, including dynamic simulations, etc. If someone is using Powerpoint to draw molecules they're not likely a professional chemist or bioc

Agreed, the time invested to learn how to make objects such as shown in Powerpoint would be better spent learning to use Illustrator or Gimp. The results would be much more useable across different media as well.

In the UK there is little pretense that any journalistic publication is truly objective, so the tradition is for opposing parties to use different channels in the media.

As to the investors contacted vs meetings plot, the red line is evidently bogus. It is likely caused by trying to fit the data to some polynomial for which there is no a priori justification. A straight-line fit would look more reasonable
