Given the rate of global warming, the fact that the world's population is growing so quickly and that we may run out of resources or run into some other calamity before one hundred years is up, and the fact that the technology needed for prolonged survival of humans in space seems pretty far off, I thought of another possibility that I wanted to ask about.

Given the current complexity of computer based technology, artificial intelligence seems like something we might be able to achieve in a reasonable amount of time. Wouldn't a silicon-based life form that could survive in space be a better bet for the continuation of our legacy rather than our survival? Consider also the distance between galaxies and how a silicon based life form could essentially eliminate the problem of "time" in space travel because of its relative immortality and the fact that it could reproduce needed parts by gathering materials; essentially scavengering them. Your thoughts

We're all doomed. Well, maybe not us but our great-grandchildren are if we don't make more of an effort to conserve energy and use renewable forms of it.

The report on global warming by economist Sir Nicholas Stern warns that if no action is taken floods from rising sea levels could displace up to 100 million people, melting glaciers could cause water shortages for 1 in 6 of the world's population, wildlife will be harmed; at worst up to 40% of species could become extinct and droughts may create tens or even hundreds of millions of 'climate refugees.' In short, global disaster. Potentially.

We're already witnessing hotter summers and milder winters. As rainfall patterns change, droughts and flooding are becoming more common. But making energy efficient measures in our homes now will give us a chance of making a difference. And cut our bills.

Global meltdown aside, the soaring costs of gas and electricity - in some cases rising by more than 90% since 2003!

Sergio said " if I toss 2 coins, I can get 2 heads, or 2 tails, or a head and a tail. There fore the probability that i get 2 heads is 1/3.

Sergio is incorrect. Explain why.?


I thouhgh the answer would be 1/3 but it isnt obviously, can anyone tell me the answer, but more importantly explain how they got this? Thanks very much.

what else would/wouldn't? Besides metal which I know wouldn't. And it has to be something that boxes (or functions like a box) are made of.
