Osmos by Hemisphere Games http://www.hemispheregames.com/osmos gives players an intuitive understanding of Newton's laws of motion and orbital mechanics. It's a great, non-mathematical introduction to physics.

Both you and the article authors are making the assumption that they want to return the ore to earth, which is ridiculous as there's already plenty of iron ore on earth. The fact that one of the team members is NASA's Mars mission planner should be a clue. Mining an asteroid with robots and sending the ore to Mars is the cheapest way to get concentrated iron ore in one spot on Mars. It's more efficient than sending it from earth or mining it on Mars.

This iron could then be used for the construction of a large Mars base. These guys are planning a lot further ahead that you give them credit for.

If these are allowed, and it turns out they do in fact provide a significant advantage over biological legs, coaches will start putting pressure on professional runners to amputate their legs and have blades fitted in the interest of their careers.

Yes. This wouldn't change my opinion of Wikipedia, rather this would make me think that a lot of slashdot posters have an over-inflated view of their own writing abilities.

Except for me, of course. [citation needed]

I feel like going through all the slashdot comments like this that basically say "I made a great edit and it was reverted for no reason" and adding [citation needed] to them, because not a single one of you has provided a link to your allegedly great edit. Maybe you're just not as good an author as you think you are? Please prove me wrong with a link.

Indeed - but a reductio ad absurdam is most effective when the initial premise (in this case that more heat is good) is false. I'm not disputing that life could exist on Venus though since it also has usable temperature gradients, as evidenced by its weather. However we're better off looking for life on a planet or moon that doesn't destroy spacecraft within an hour of their landing on the surface, which Venus does.

I assume then that the interior of the sun would be a good place to look for life, because of all the heat?

You don't need a high temperature to drive the chemistry of life - you need a temperature gradient so that work can be done by transferring heat energy from one location to another. Titan has this due to internal heating from tidal forces, as has Europa. Life may operate at a slower pace in a cold environment, but the right catalysts could improve this.

Gamers 4 Croydon are running a candidate against Michael Atkinson in the next election for the Croydon seat. Vote for them if you really want to see an R18+ rating in Australia.

Perhaps Conroy will bring a copy of the official list with him, to prove that this leaked list isn't the same. To any Australians reading - the solution to this problem is simple. Do not vote Labor! And tell all your Aussie friends to not vote Labor too.

Harpooned is the world's finest cetacean research simulator. It's free, runs on low spec machines and I made it.
