Re: 1782: "Team Chat"

So what you're saying is that IRC is the only stable platform here, while the alternatives are temporary fads? That was also my take on it. For text chat I don't think anything is better than IRC. Voice/video chat is another matter, and unfortunately I'm unaware of a similar established open standa...

Re: Can a compound be denser than it's densest element?

Thanks for the answers. What I'm most interested is in the high end of the density scale, because those heavy elements are very rare, as they are hard to produce by stellar events, and tend to sink down away from the crust by earths gravity. And the heaviest ones are usually very unstable, radioacti...

Can a compound be denser than it's densest element?

Can a compound be denser than the densest element it is made from? I think that compound may end up lighter than the original elements, because it may form crystalline structures, and so on (real examples would be cool too). But can it end up denser? A related question: is there something denser tha...

Re: [Biology] Are we pooing correctly?

On squatting not being as comfortable as sitting, you should consider that the time spent pooping will be shorter [1]. Sitting for long periods of time on a toilet seat, that isn't a soft couch, will likely block circulation on legs that adds on the discomfort of the hard to get out poop itself. On ...

Re: What-if 0007: Everybody Out

I assume that the launch platform could not exceed 1km (the height of a tall skyscraper). I originally calculated Df ~ 7.2156*10^7. This corresponds to a deceleration rate of about 7m/s^2. This is slightly less than one g. Finally a good reason for heavy rockets. Also the boosters could be fired up...
