... of why libertarians are wrong about the role of governments.

Free markets are nothing that comes about naturally. It is the governments that create the regulatory framework that allows for free markets to function.

Business hurt when governments fail in this most important job.

+ - Most planets in the Universe are homeless

Yes, there's some variety, with binary or trinary star systems and huge variance in the masses of the central star being common ones, but from a planetary point of view, our Solar System is a rarity. Even though there are hundreds of billions of stars in our galaxy for planets to orbit, there are most likely around a quadrillion planets in our galaxy, total, with only a few trillion of them orbiting stars at most. Now that we've finally detected the first of these, we have an excellent idea that this picture is the correct one: most planets in the Universe are homeless. Now, thank your lucky star!"

+ - Is Geometric Algebra finally adopted in STEM curricula?->

Submitted by quax
quax (19371) writes "It has been over a century that William Kingdon Clifford developed Geometric Algebra. Yet due to his untimely death it was quickly forgotten, only to be partially reinvented when Dirac tackled relativistic quantum mechanics and introduced spinors. But geometric algebra is much more versatile than that, for instance it makes for a better alternative to vector calculus, combining div and curl operators and doing away with the cross-product in favor of bivectors. It is such a straightforward unification of otherwise, disparate mathematical techniques that I very much regret that my physics curriculum twenty years ago didn't cover it. Has this changed? Have you encountered geometric algebra in an undergraduate program?"

Don't think accelerator reliability issues are much of a concern any more, the systems are pretty mature at this point. I see the many advantage in being able to produce tailored neutron energy spectrum to process as much waste as possible.

The latter is the main focus in my mind. Excess energy is just an added bonus. We need a process like this as burying the nuclear crap has become a politically untenable.

The reason why worry kills more people than work is that more people worry than work.
