Earth Overshoot Day

Oops! We used up the last resources of our planet yesterday… Should I be worried since it was my birthday? :O (Or perhaps I have completely other reasons for concern?)

The concept was apparently invented by Global Footprint Network. Here’s a link to their overshoot page: http://www.footprintnetwork.org/gfn_sub.php?content=overshoot

Has the Large Hadron Collider destroyed the world yet?

You may have heard of the Large Hadron Collider or perhaps concerns about its safety, and if not you may still have come across this funny web page to test if it has destroyed the world yet.

Check the source for the last one as well, there are a few laughs. Their test to see if the world has ended is:

if (!(typeof worldHasEnded == "undefined")) {
    document.write("YUP.");
} else {
    document.write("NOPE.");
}

If the undefined variable worldHasEnded is not “undefined” then there’s some really spooky stuff going on… like the end of the world… otherwise we’re all safe and sound. In the same spirit I’m offering a test for world destruction for Java (and possibly C++ and other object oriented languages as well):

System.out.print("Has the Large Hadron Collider destroyed the world yet? ");
if (this == null) {
    System.out.println("Yes!");
}
else {
    System.out.println("Nope");
}

Is the object running this test not existing any more… then risk is neither is the rest of the world…

Of course, we’ll have to wait until sometime in the end of October or beginning of November before they actually start colliding protons… and then perhaps the world will end…

The Selfish Gene

Richard Dawkins discusses in his book “The Selfish Gene” if we are using our genes to propagate ourselves, or if maybe our genes are using us to propagate themselves.

According to Dawkins life may very well have begun a long time ago, in the primordial soup, when simple clumps of amino-acids became self-replicating. This self-replication started a kind of war between competing replicators and who was on top (or in the majority) in the soup probably changed many times until one kind of replicators using a protective layer of matter came out the winner (one cell organisms).

Evolution — a guessing game…

Does evolution really work? Has it really made us what we are today? Surely the chance of just randomly creating human life must be “zero many times over”, right?

I’ve read quite a few pages from the more fundamental and lively bunch of Creationists and Intelligent Design aficionados (like for instance this one), and I’ve frankly grown tired of this talk about randomly creating life…
