Sidney Coleman (1937–2007) was a renowned theoretical physicist, who taught for more than forty years at Harvard University. He contributed critical work on quantum field theory, high-energy particle physics, and cosmology. He was also a remarkably effective teacher who introduced generations of physicists to quantum field theory, mentoring several leading members in the field. His sense of humor and wit became legendary. This selection of his previously unpublished correspondence illumina...

The vacuum is central to physicists' best theories of subatomic particles, gravitation, and cosmology. Nothingness provides the reference point with which to compare new particle creation and annihilation. Cosmologists use empty universes to study the causal structure of spacetime. Paradoxically, our best physical theories of particles, gravity, and spacetime are theories of nothingness. Stranger still, the physicists' vacuum is a hive of activity. Quantum fluctuations fill empty space wit...

In a post-apocalyptic world where every government in the world has been overrun by its own military machinery, only to see that military machinery self-destruct, people are randomly being affected by a plague that seemingly takes over their brains and forces them to commit heinous crimes. Chandler is one of these unfortunate victims, the perpetrator of rape and murder. He is driven out of his community as a Hoaxer (someone who feigns being a victim of the plague), branded on his forehead ...

Since Bitcoin appeared in 2009, the digital currency has been hailed as an Internet marvel and decried as the preferred transaction vehicle for all manner of criminals. It has left nearly everyone without a computer science degree confused: Just how do you "mine" money from ones and zeros?The answer lies in a technology called blockchain, which can be used for much more than Bitcoin. A general-purpose tool for creating secure, decentralized, peer-to-peer applications, blockchain te...

The definitive pioneering blueprint covering the what, why, and how of the blockchainBlockchains are new technology layers that rewire the Internet and threaten to side-step older legacy constructs and centrally served businesses. At its core, a blockchain injects trust into the network, cutting off some intermediaries from serving that function and disrupting how they operate. Metaphorically, blockchains are the ultimate non-stop computers. Once launched, they nev...
