Secrets of the Antikythera Mechanism In 1900, sponge divers off the coast of the tiny Greek island of Antikythera made an astonishing discovery: the wreck of an ancient Roman ship lay 200 feet beneath the water, its dazzling cargo spread out over the ocean floor. Among the life-size statues and amphorae was an encrusted piece ...
The Arctic is rapidly warming with continued changes in sea ice, ocean chemistry, and marine ecosystems. Increased heat import via the atmosphere, flows from the Atlantic and Pacific Oceans, and increased river runoff into the Beaufort Sea have dramatically reduced sea ice extent and thickness. We hypothesize that temperature, sea ...
Chiral asymmetry choices exhibited by molecules present in living organisms constitute a scientifically challenging set of observations. Such geometric preferences favoring one enantiomer over its mirror image are obvious in the structures of amino acids, sugars, and the biopolymers that they form. These facts generate fundamental questions about how those ...
Randomness is essential to cryptography: cryptographic security depends on private keys that are unpredictable to an attacker. But how good are the random number generators that are actually used in practice? In this talk, I will discuss several large-scale surveys of cryptographic deployments, including TLS, SSH, Bitcoin, and secure smart ...

Author and physicist Leonard Mlodinow (PhD, UC Berkeley) will explore how humans have won such a grand grasp of nature's workings - and what deeper understandings may lie ahead. He is the author of five bestsellers including two co-written with Stephen Hawking: A Briefer History of Time and The Grand Design. Dr. Mlodinow's The ...
Governor Jerry Brown is determined to build the Delta Tunnels through the Sacramento/San Joaquin River Delta. The once-and-future Peripheral Canal is the latest plumbing scheme to follow the damming and diking of rivers and swamps which began with intensive Chinese manual labor in the 19th century. California has already radically ...
