I can hardly believe this. This woman is making her own transistors with silicon wafers and a few chemicals, some of which are from the hardware store.
She made a MOSFET, incredibly.

The Decision Tree with Wired editor Thomas Goetz
Marin Science Seminar visited Kishore Hari’s Down to a Science cafe in San Francisco last week and participated in a fun game-show style presentation on using technology to make and track personal medical decisions. One of the kids got to play the part of a basketball player with a genetic heart condition which might preclude him from continuing his lucrative career. Wisely, he chose not to continue playing so he wouldn’t suddenly drop dead. Wired editor Thomas Goetz ran the show while explaining how new technologies can help us to make better medical and personal health choices. He then entertained a lively discussion on health care, bioethics and physician vs. patient access to expertise. Here is a pic of some of the MSS young people with Kishore and Thomas, and a copy of Thomas’s book The Decision Tree, which he very generously signed and gave to each of the game-show participants. A edutaining time was had by all!
Sun, Skin Cancer, and the Highlands of Guatemala with James Cleaver, PhD of UCSF
Dr. Cleaver will describe the discovery of a Guatemalan village with a high incidence of skin cancer and his lab’s plans for their care. The genetic cause is a failure to repair sunlight damage to DNA. Repair of DNA is a mechanism our bodies possess for protection against all kinds of environmental exposures. DNA repair defects are involved in many kinds of cancer and neurodegenerative disease. Get the flyer here. (April 21, 2010)
Dr. Cleaver gained his BA and PhD at the University of Cambridge, England. He spent two years as a postdoctoral student at Harvard, and joined the faculty of UCSF in 1966 in the Laboratory of Radiobiology and Environmental Health, and became the research director. He discovered that the basis of xeroderma pigmentosum was a DNA repair deficiency in 1968, and has worked on this and related diseases ever since. He was granted Emeritus status at UCSF in January 2004, but continues to carry out research. His appointments as Professor are held in the Departments of Dermatology and of Pharmaceutical Chemistry and he is a member of the UCSF Cancer Center.
Dr. Cleaver is an internationally recognized expert on the molecular mechanisms of environmentally-induced and genetically-determined human cancers. He demonstrated as early as 1968 that cancer can be viewed as a genetic disease and his revolutionary work on xeroderma pigmentosum has led to breakthroughs in our understanding of the link between DNA repair efficiency and human disease. His pioneering work has resulted in more than 350 papers and reviews. He received research awards from the Radiation Research Society (1973), American Academy of Dermatology (1976), the Phycological Society (1991), Harvard University JB Little award (2003), the UCSF Faculty Research lectureship (2004) and the American Skin Association (2006), He was elected to the National Academy of Sciences in 1999.

Analysis and Dating of Ancient Chinese Jade with Sam Bernstein
Mr. Sam Bernstein will lecture on the topic of stylistic and physical examination techniques utilized in authenticating ancient Chinese Works of art. The usefulness of art historical and scientific testing techniques give us a valuable tool kit for understanding how ancient artists worked. Get the flyer here. (March 3, 2010)
Sam Bernstein is an internationally recognized authority on Chinese jades. His company, S. Bernstein & Co., deals in Chinese jade, antiquities, and rare books on China and jade. It is located on the first floor of the Fairmont Hotel, San Francisco.
Why are there Stars?
with Steven Stahler, Ph.D.
Wed. February 24, 2010
On a clear night, the sky is filled with countless stars. Our Sun is one of them. How do these objects form? In recent decades, astronomers have begun answering this very old question. This progress has occurred despite the fact that the youngest stars are invisible to the eye and even to most telescopes. Along the way, we have learned how planets like the Earth are created as part of the stellar birth process. (February 24, 2010) Get the flyer here.
Dr. Steven Stahler is an astrophysicist at U. C. Berkeley. Raised in Maryland, he attended graduate school at UC-Berkeley in physics. He was a professor at MIT before returning to the Bay Area in 1992. His research centers on the problem of star formation, and he recently coauthored the first comprehensive textbook in the field (“The Formation of Stars,” Stahler & Palla, Wiley-VCH, 2004). Trained as a theoretical physicist, Steve especially delights in the esthetic aspect of his research, which he tries to convey in his numerous public talks.
“We Are Stardust: Genesis of the Elements” with Mary Barsony, Ph.D.
Marin Science Seminar Presentation: “We Are Stardust: Genesis of the Elements” Dr. Barsony’s talk focuses on how stars shine and how they have generated the elements. (February 3, 2010) Get the flyer here.
One of the fundamental goals of astronomy and astrophysics is to understand how the Universe and its constituent galaxies, stars, and planets formed, how they evolved, and what their destiny will be. Dr. Barsony’s research is focused on the formation of stars out of the raw material provided by tenuous interstellar gas found in frigid clouds in our Galaxy. Since the present birthplaces of stars are hidden by interstellar dust mixed in with the gas, exploring the detailed mechanisms involved in star (and planetary system) formation requires observations at wavelengths whose passage is relatively unimpeded by the intervening dust: radio, millimeter, submillimeter, infrared, and X-ray wavelengths.
Through submillimeter observations in the early ‘90’s, Dr. Barsony helped identify the first true protostar—an object surrounded by infalling gas that is in the process of accumulating the mass it will have as a full-fledged star. Such objects are rare, and the focus of intense current (and future) study, with space-based observatories such as the Spitzer Space Telescope, the Herschel Observatory, and the planned JWST (Hubble’s replacement that wil operate at infrared wavelengths).
Dr. Barsony is Adjoint Professor of Physics & Astronomy at San Francisco State University and a Research Scientist at the Space Science Institute. She earned her Ph.D. from CalTech and her S.B. from MIT.

How to Bring Solar Energy to Seven Billion People
“How to Bring Solar Energy to Seven Billion People” with Cyrus Wadia, Ph.D.
November 4, 2009
Dr. Wadia is a pioneer in bringing a multidisciplinary approach to solving the complicated issue of renewable energy. Join him in a lively discussion on the promise -and the pitfalls – of solar energy. Download the flyer here.
In the city of San Rafael, the only way solar energy can be cost-effective is if the local government provides generous subsidies. That’s true just about everywhere in the world. But what if there were a photovoltaic technology that was so cheap and so easy to install that even the poorest and most remote villages of the world could gain access to electricity? In this presentation, learn about discoveries of new materials that can make solar energy a reality for billions.
By exploiting the powers of nanotechnology and taking advantage of non-toxic, Earth-abundant materials, Cyrus Wadia has fabricated new solar cell devices that have the potential to be several orders of magnitude less expensive than conventional solar cells. And by mastering the chemistry of these materials – and the economics of solar energy – he envisions bringing electricity to the 1.2 billion people now living without it.
Dr. Wadia holds an MS in Chemical Engineering from MIT and a PhD in Energy Resources from UC-Berkeley. He is currently a postdoctoral fellow at the Lawrence Livermore Laboratory in Berkeley. Dr. Wadia spent six years in the high tech industry, has specialized in launching new technologies to market and has completed several successful new product introductions. Presently, Cyrus continues his work helping companies take technology to market as part of an independent consulting practice he began in 2001.
