We humans interact with our physical environment through our senses of touch, sight, smell, taste, and hearing. One of the great challenges in developing artificial intelligence and natural interfaces between humans and machines is finding ways to emulate those senses...

Among the many beautiful, unexpected and sometimes revolutionary discoveries to emerge from subatomic physics, probably none is more bizarre than an elementary particle known as the "neutrino". More than a trillion of these microscopic phantoms pass unnoticed through our bodies...

The enigmatic neutrinos are among the most abundant of the tiny particles that make up our universe. They are a billion times more abundant than the particles of which the earth and we humans are made. Thus, to understand the...

A irreverent non-technical review of the history of surprisingly animate machines, from ancient Egypt to current times. Areas include teleoperators for hazardous environments, assembly systems, medical applications, entertainment, and science fiction. The talk has over 100 slides, covering such varied...

SLAC has converted its giant particle accelerator into the world's first X-ray laser. By a billion fold the world's brightest X-ray source, the laser packs a trillion photons into pulses as short as a millionth of a billionth of a...

As electronics become faster and more powerful and the components of integrated circuits shrink, scientists are bumping up against the limitations imposed by fundamental physics, forcing them to invent new technologies. Today computer hard drives store information in tiny magnets...

Particle physicists have a description of the forces of nature known as the Standard Model that has successfully withstood decades of testing at laboratories around the world. Though the Standard Model is powerful, it is not complete. Important details like...
