...time it ended, just a couple hundred million years later, the universe was alight with young stars gathered into nascent galaxies. It was during the Dark Ages that the chemical elements we know so well--carbon, oxygen, nitrogen and most of the rest--were first forged out of primordial hydrogen and helium. And it was during this time that the great structures of the modern universe--superclusters of thousands of galaxies stretching across millions of light-years--began to assemble...
...Some regions were a tiny bit denser than average and some a little more sparse. Most of the stuff in it--then and still today--was the mysterious dark matter that nobody has yet identified, largely because it doesn't produce light of any sort. The rest was mostly hydrogen, with a bit of helium mixed in. So far, the universe hadn't done much of anything...
...ideology as flesh--and al-Qaeda has largely devolved or maybe evolved into a franchise operation. Radical groups in various countries are largely self- activated and self-sustaining, though they may check in with top management before a major assault, as did the Saudi cell that in 2003 plotted hydrogen cyanide attacks in the New York City subways. Al-Qaeda No. 2, Ayman al-Zawahiri, called off that scheme, preferring, U.S. officials believed, to prepare for something bigger...
...electricity is still cheaper than gas-produced power. Supercritical - and now ultra-supercritical - boilers have an additional advantage: they can be retrofitted into older, dirtier plants. Another, slightly less efficient, way to use coal is through integrated gasification combined cycle (igcc) technology, which gasifies coal and uses the resulting hydrogen and carbon monoxide mix to spin the turbines...
Hilbert responded kindly and quite generously the following day, claiming no priority for himself. "If I could calculate as rapidly as you," he wrote, "in my equations the electron would have to capitulate and the hydrogen atom would have to produce its note of apology about why it does not radiate." Yet one day later, Hilbert sent a paper to a scientific journal with his own version of the equations for general relativity. The title he picked for his piece was not a modest one. "The Foundations of Physics," he called...
