Euler's Solution to the Basel Problem I'm in the mood for some math today, so here's an amusing little proof I recently showed to my History of Mathematics class. We shall derive the formula \[ \frac{\pi^2}{6}=1+\frac{1}{4}+\frac{1}{9}+\frac{1}{16}+\frac{1}{25}+\dots \] Note that the denominators of the fractions on the...

“That's why helium recycling is important. If I don't recycle my aluminum can, the problem isn't that we lose the aluminum from the earth, it's just that it will take more energy to get those atoms back into a useful form than if I recycled it. If I don't recycle my helium (and my guess is most users don't), the atoms eventually leave the planet.” Anonymous Coward on Why is Helium so Scarce?

Synthetic Biology
Some engineers use cranes and steel to make their designs reality, but synthetic biologists engineer using tools on a different scale: DNA and the other molecular components of living cells. Synthetic biology uses cellular systems and structures to produce artificial models based on natural order. Read these posts from the ScienceBlogs archives for more:
