Science Magic Show Part I
on: sciencelive
Sue McGrath performs a range of experiments on her 'willing volunteer' Matt Cunningham. Matt gets balloons exploded over his head, and they test gases to see if they are explosive. Sue shows Matt how to make ice cream in sixty seconds, and pour a cup of water over your head without getting wet!

Briefing: Documenting Endangered Languages
on: National Science Foundation
Linguistics experts estimate that almost half of the world's 6,000-7,000 existing languages--and the cultural, linguistic and cognitive information they encapsulate--are headed for oblivion. The National Science Foundation, in partnership with the National Endowment for the Humanities, has launched a multi-year 'rescue mission' to document and preserve key languages before they become extinct. More than 70 at-risk languages will be digitally archived as part of the new Documenting Endangered Languages (DEL) program.

Information Security-Before, During, and After Public-Key Cryptography
on:
In the 1970s, the world of information security was transformed by public-key cryptography, the radical revision of cryptographic thinking that allowed people with no prior contact to communicate securely. Public key solved security problems born of the revolution in information technology that characterized the 20th century and made Internet commerce possible. Security problems rarely stay solved, however. Continuing growth in computing, networking, and wireless--including applications made possible by improvements in security-have given rise to new security problems. Where is this going? Diffie, a key figure in the discovery public-key cryptography, will trace the growth of information security through the 20th Century and into the 21st.

SLAC
The Linac Coherent Light Source Project at SLAC
on: Fermilab Colloquium Lectures
The Linac Coherent Light Source (LCLS) is an x-ray free-electron laser project presently under construction at SLAC. A 14-GeV high-brightness electron beam is produced in the last kilometer of the existing SLAC linear accelerator, generating coherent x-ray radiation in a 130-m long undulator. The peak x-ray brightness is 10 orders of magnitude higher than existing 3rd generation light sources with a wavelength of 1.5 Angstroms and a pulse duration as short as one femtosecond, opening limitless scientific opportunities in the world of the ultra-small and ultra-fast. This presentation will describe the project scope and status, highlighting especially the key accelerator physics challenges.

Can math tell what happened?
on: sciencelive
My objective in this presentation is to show that mathematics is important and highly relevant to crime fighting in particular, and to many other real life problems in general. Hopefully this will give an answer to the often asked question what's the use of mathematics?

The 40th Anniversary of Moore's Law
on:
This year marks the 40th anniversary of Moore's Law, Gordon E. Moore's 1965 observation and prediction about the exponential growth in the power of semiconductor technology. Moore observed that semiconductor technology had doubled in power every year and predicted that it would continue along this developmental path. Originally named Moore's Law several years later by the physicist Carver Mead, that simple observation has proven to be the bulwark of the world's most remarkable industry. In 1975, Moore updated this to a doubling about every two years. History has thus far proven Moore's law correct, and this special conversation between Moore and Mead looks back on the past 40 years on what has made this electronics revolution possible.

He will also explore the likely consequences if he is correct.

String Theory for Pedestrians Part I
on: CERN
In this 3-lecture series I will discuss the basics of string theory, some physical applications, and the outlook for the future. I will begin with the main concepts of the classical theory and the application to the study of cosmic superstrings. Then I will turn to the quantum theory and discuss applications to the investigation of hadronic spectra and the recently discovered quark-gluon plasma. I will conclude with a sketch of string models of particle physics and showing some avenues that may lead to a complete formulation of string theory.

Atomic-Layer Engineering of Cuprate Superconductors - 415th Brookhaven Lecture by Ivan Bo_ovi_
on: Brookhaven National Laboratory
Copper-oxide compounds, called cuprates, show superconducting properties at 163 degrees Kelvin, the highest temperature of any known superconducting material. Cuprates are therefore among the high-temperature superconductors of extreme interest both to scientists and to industry. Research to learn their secrets is one of the hottest topics in the field of materials science. May 17, 2006

The Rise of Silicon Valley: From Shockley Labs to Fairchild Semiconductor
on:
On February 13, 1956, co-inventor of the transistor William Shockley formally announced the establishment of Shockley Labs, Silicon Valley's first semiconductor company. In their modest Quonset hut laboratory on San Antonio Avenue in Mountain View, Shockley's hand-picked team of some of the nation's brightest young scientists and engineers developed innovative technologies and ideas that forever changed the way we live, work and play. To celebrate the 50th anniversary of this pivotal event in the history of our region, join technology historian Michael Riordan in a conversation between early Shockley employees and associates Jim Gibbons, Jay Last, Hans Queisser, and Harry Sello.

The Pleasure of Finding Things Out
Speaker: Richard Feynman
Time: 50 minutes Fifty minutes of PURE Feynman! This is the original Horizon Nova interview - essential for any Feynman fan... and for everyone else too!
THE PLEASURE OF FINDING THINGS OUT was filmed in 1981 and will delight and inspire anyone who would like to share something of the joys of scientific discovery. Feynman is a master storyteller, and his tales -- about childhood, Los Alamos, or how he won a Nobel Prize -- are a vivid and entertaining insight into the mind of a great scientist at work and play.
'The 1981 Feynman Horizon is the best science program I have ever seen. This is not just my opinion - it is also the opinion of many of the best scientists that I know who have seen the program... It should be mandatory viewing for all students whether they be science or arts students.' - Professor Sir Harry Kroto, Nobel Prize for Chemistry
