The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to double by mid-century and triple by the end of the century. Even in light of unprecedented conservation, the additional energy needed is simply not attainable from long discussed sources these include nuclear, biomass, wind, geothermal and hydroelectric. The global appetite for energy is simply too much. Petroleum-based fuel sources (i.e., coal, oil and gas) could be increased. However, deleterious consequences resulting from external drivers of economy, the environment, and global security dictate that this energy need be met by renewable and sustainable sources. The dramatic increase in global energy need is driven by 3 billion low-energy users in the non-legacy world and by 3 billion people yet to inhabit the planet over the next half century. The capture and storage of solar energy at the individual level personalized solar energy drives inextricably towards the heart of this energy challenge by addressing the triumvirate of secure, carbon neutral and plentiful energy. This talk will place the scale of the global energy issue in perspective and then discuss how personalized energy (especially for the non-legacy world) can provide a path to a solution to the global energy challenge. Daniel G. Nocera is the Henry Dreyfus Professor of Energy at the Massachusetts Institute of Technology, Director of the Solar Revolutions Project and Director of the Eni Solar Frontiers Center at MIT. His group pioneered studies of the basic mechanisms of energy conversion in biology and chemistry. He has recently accomplished a solar fuels process that captures many of the elements of photosynthesis outside of the leaf. This discovery sets the stage for a storage mechanism for the large scale, distributed, deployment of solar energy. He has b

Free Download - StanfordUniversity - January 22, 2009 - Karl Deisseroth is pioneering bold new treatments for depression and other psychiatric diseases. By sending pulses of light into the brain, Deisseroth can control neural activity with remarkable precision. In this short talk, Deisseroth gives an thoughtful and awe-inspiring overview of his Stanford University lab's groundbreaking research in "optogenetics".

"In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

Aubrey de Grey passionately talks about the ultimate quest for significantly longer, healthier life! A must view talk!

In late 2009, Charles Robinson was able to interview Peter Joseph, the creator of Zeitgeist: The Movie, Zeitgeist: Addendum, Zeitgeist: Moving Forward, several lectures and a presentation; Founder of The Zeitgeist Movement and a friend of Jack Fresco, in his home. He described himself and his life in details in what is likely a rare interview. He was kind enough to provide him with previously unreleased media and video and in turn Charles did his best to create a documentary (albeit kinda poor in quality compared to his work!) that would help express who this person is. Peter Joseph was born in North Carolina to a middle class family. He has said in interviews that his mother's role as a social worker helped shape his opinion and impressions of American life. He later moved to New York to attend art school. Currently he lives and works in New York City as a freelance film editor/composer/producer for various industries. Due to the controversial content of his films and a desire to keep his day job private, he has not released his full name to the public.

He predicts that quantum computers will be produced within 20 years. ----- The two towering achievements of modern physics are quantum theory and Einsteins general theory of relativity. Together, they explain virtually everything about the world in which we live. But almost a century after their advent, most people havent the slightest clue what either is about. Radio astronomer, award-winning writer and broadcaster Marcus Chown talks to fellow stargazer Fred Watson about his book Quantum Theory Cannot Hurt You. - Australian Broadcasting Corporation Marcus Chown is an award-winning writer and broadcaster. Formerly a radio astronomer at the California Institute of Technology, he is now cosmology consultant of the weekly science magazine New Scientist. The Magic Furnace, Marcus' second book, was chosen in Japan as one of the Books of the Year by Asahi Shimbun. In the UK, the Daily Mail called it "a dizzy page-turner with all the narrative devices you'd expect to find in Harry Potter". His latest book is called Quantum Theory Cannot Hurt You.

With its expansive range and unprecedented potential for anonymity, (the Internet gives voice to our deepest urges and most uninhibited thoughts. Inspired by the wealth of unfettered expression available online, neuroscientists Ogi Ogas and Sai Gaddam, who met as Ph.D. candidates at Boston University, began plumbing a few chosen search engines (including Dogpile and AOL) to create the world's largest experiment in sexuality in 2009. Quietly tapping into a billion Web searches, they explored the private activities of more than 100 million men and women around the world. The result is the first large-scale scientific examination of human sexuality in more than half a century, since biologist Alfred Kinsey famously interviewed more than 18,000 middle-class Caucasians about their sexual behavior and published the Kinsey reports in 1948 and 1953. Building on the work of Kinsey, neuroscientists have long made the case that male and female sexuality exist on different planes. But like Kinsey himself, they have been hampered by the dubious reliability of self-reports of sexual behavior and preferences as well as by small sample sizes. That is where the Internet comes in. By accessing raw data from Web searches and employing the help of Alexa-a company that measures Web traffic and publishes a list of the million most popular sites in the world-Ogas and Gaddam shine a light on hidden desire, a quirky realm of lust, fetish, and kink that, like the far side of the moon, has barely been glimpsed. Here is a sampling of their fascinating results, selected from their book, A Billion Wicked Thoughts.

This flu season, people with a fear of needles have an alternative. A new device made by PharmaJet uses spring tension to produce a high velocity jet of air to deliver medications and vaccines through the skin. Most people coming in for the flu shot at the Andover Senior Center still opted for the standard needle but the new way is gaining popularity. Nearly one third of those getting a vaccine chose the PharmaJet. (Video by Andre Malok/The Star-Ledger)

short summary of some probabilistic responses to the problem of induction

Do we remain one species, or diverge into many? Do we remain of many minds, or merge into one?

Students interested in the philosophy of science, the history of science, and/or logic may face the choice of whether to pursue a graduate degree in a traditional philosophy department, or in a separate department of history and philosophy of science (HPS), or logic and philosophy of science (LPS).

...Historians of science have always had a soft spot for the history of theoretical physics. The great theoretical advances of this century -- relativity and quantum mechanics -- have been documented in fascinating historical accounts that have captivated the mind of the cultivated public. There are no comparable studies of the relations between science and engineering. Breaking with the tradition of the Fachidiot, theoretical physicists have bestowed their romantic autobiographies on the world, portraying themselves as the high priests of the reigning cult.

When we talk about participation, we have to be a bit more specific. On the publishing side, there's clearly more participation than we've ever seen in the past. But in order for this tidal wave of information to be useful, we need to be able to separate fact from fiction. We need to encourage participation on the receiving end. What we need is evaluating participation. With the breadth of niche information and sources we have the ability to get at the best of what is known on a myriad of topics and contexts. Every niche has its experts and its hacks, its enthusiasts and detractors. But for the remaining 95% of us who are not subject matter experts, deriving the accurate or useful information from the sea of what is available can be complicated, time-consuming and simply unverifiable. We need a way to quantify the value of information, or more specifically, the veracity of information.
