Dr.Ken Farquhar

Science in a Suitcase
on: sciencelive
Dr Ken Farquhar and his able assistant Ian Walker take over ScienceLive to demonstrate 'Science in a Suitcase'. After throwing out Matt they demonstrate 'sideways gravity' - how moving objects to the side will cause some objects to fall straight down. They also show us the British Space mission, involving an electric drill, beach balls and a variety of exciting planetary objects!! They then show us to spin water around their head without making a mess on the floor. A must for all of those still young at heart!!

Diffusion-Mediated Regulation In Endocrine Cell Networks
on: Caltech
Donald S. Cohen, Charles Lee Powell Professor of Applied Mathematics, Emeritus, Caltech; Danny Petrasek, Senior Research Fellow, Applied and Computational Mathematics, Caltech; and William Goodman, Professor of Medicine, UCLA, presented this lecture as part of the 0.1 Seminar series. They discuss a computational model that demonstrates diffusion-mediated regulation and that shows qualitative agreement with published experimental results. Such a signaling mechanism may regulate other networks with similar biochemical and geometric properties.

Jeff Hawkins

The PalmPilot Story
on:
The late 1980s and early 1990s buzzed with corporations and startups trying to develop portable computers that used a pen as the means of interaction. By late 1993, every one of these efforts had failed. Though running out of funding, one of these startups, Palm Computing, went on to launch the Pilot organizer and Palm operating system, which triggered the handheld computing industry. In this talk, Jeff Hawkins, Donna Dubinsky, and Ed Colligan discuss the roots of handheld computing, how Palm learned from failure, and the challenges of battling conventional technology wisdom. Andrea Butter, former Palm marketing executive and co-author of Piloting Palm will facilitate the discussion.

Richard F. Lyon

Pixels and Me
on:
Computers have revolutionized image media. Richard Lyon, one of the current pioneers of digital cameras, has found that several generations of pioneers in this field have been entangled with the terms picture element and pixel and that studying the history of the terminology is a fruitful approach to the history of the people and technology. Vladimir Zworykin's television research group at RCA popularized the term picture element in the 1930s, while the TV researchers at Bell Labs ignored that term, preferring image element. Fred Billingsley and others at the Jet Propulsion Laboratory developed computerized image processing and propagated the term pixel in the 1960s, while image processing researchers at Bell Labs ignored that term, preferring pel. In the early 1970s, pixel was spread through computer image processing publications from NASA, USC, IBM, Stanford, University of Missouri, and other places, eventually coming to be applied to elements of image sensor hardware, such as Lyon's optical mouse in 1980 and digital camera sensors more recently. Many of the people involved in this complex history have provided their personal recollections and documents to help piece the story together, and more such inputs will be solicited from the Computer History Museum audience.

Robert Walsh

Living with a Star-an encounter with Robert Walsh
on: sciencelive
Currently Robert is a Senior Lecturer in Astrophysics and Mathematics at the University of Central Lancashire, Preston, UK. His area of research is Solar Physics, where he uses space-based solar observatories (solar observing satellites) to monitor our closest star and then set-up sophisticated super-computer simulations to try and reproduce what we observe. He is married to Heather and has two children, Matthew (aged three) and Emma (aged 6 weeks).

Maximum Likelihood Estimation for a Gene Regulatory Network Defined by Differential Equations
on:
Gene regulation may be described by a set of deterministic differential equations describing the time rate evolution of the gene product concentrations, and containing parameters accounting for the regulatory relationships occurring in the gene network. We will present maximum likelihood based estimators of the parameters arising in this formalism and we will prove that they have desirable properties. Our results may be applied to a gene regulation model yielding the early Drosophila segments formation relying on a statistical modelling of gene expression data obtained by confocal laser scanning microscopy. The proposed statistical model accounts for the uncertainty in the measurement of gene expression and the uncertainty in the time at which the measurements are performed.

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
