Einstein proves ghosts exist; Ogopogo (video)

LiveScience.com
Ghosts are not only for Halloween and Friday the 13th (lifeslittlemysteries.com).

Every night, amateur ghost-hunting groups across the country head out into abandoned warehouses, old buildings and cemeteries to look for ghosts.

They often bring along electronic equipment that they believe helps them locate ghostly energy. Despite years of efforts by ghost hunters on TV and in real life, we still do not have good [enough] proof [for ideologue skeptics] that ghosts are real.

Many ghost hunters believe that strong support for the existence of ghosts can be found in modern physics. Specifically, that Albert Einstein, one of the greatest scientific minds of all time, offered a scientific basis for the reality of ghosts. More

Minute Physics: Light, Fire, Duality (video)





() Light it up! Fire it up! We explain a lot of hot stuff. It might be a candle in microgravity. Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in a minute! In this episode we explain why fire is red, gas flames are blue, and why you're too cool to glow. Music by Nathaniel Schroeder.

"How the Hippies Saved Physics" [Excerpt]

(W.W. Norton & Company)

Loose hippies save stiff science? A new book documents the overlooked contributions of a loose-knit, unconventional bunch of 1970s physicists called the Fundamental Fysiks Group.

Rarely can we date with any precision the ebbs and flows of scientists’ research styles or intellectual approaches. Yet these transitions -- the how’s and why’s behind major shifts in a scientific field’s reigning questions and methods -- have long held a special fascination for me. We see laid bare in these moments a messy alchemy, intermixing the world of institutions with the world of ideas. Brilliant insights and dazzling discoveries take their place alongside political decisions, funding battles, personal rivalries, and cultural cues. These many ingredients combine to make one agenda seem worth pursuing in a particular time and place -- and worth teaching to students -- while quietly eclipsing other questions or approaches that had beckoned with equal urgency only a few years earlier.

Preparing for the SAT Monster (video)

()

It's never too early/late to study, to practice, or to take it again. Here is quick, practical SAT advice. Check out all of BrightStorm's helpful tools and tips for the SAT. And remember, according to Wisdom Quarterly, only girls really understand higher level math. If only more would study and enjoy it at a lower level.

Breaking the Spell of Religion (audio)

Exploration with Dr. Michio Kaku (Saturday, July 16, KPFK.org)
Breaking the Spell (skeptic.com)

Can science explain religion as a natural phenomenon -- or set of phenomena useful to human beings in spite of the absence of a "God" as conceived of in human cultures?
Dr. Dennett, an atheist and liberal, takes a serious look at the possibility that religions may serve an important and beneficial evolutionary purpose. He is interviewed by theoretical physicist, cofounder of string field theory, and peace activist Dr. Kaku, City College of New York (CUNY). This is followed by a discussion with Steven Pinker, author of The Blank Slate: the Modern Denial of Human Nature.

In The Blank Slate, one of the world's leading experts on language and the mind explores the idea of human nature and its moral, emotional, and political colorings.

With characteristic wit, lucidity, and insight, Steven Pinker argues that the dogma that the mind has no innate traits -- a doctrine held by many intellectuals during the past century -- denies our common humanity.

It also denies our individual preferences, replaces objective analyses of social problems with feel-good slogans, and distorts our understanding of politics, violence, parenting, and the arts.

Injecting calm and rationality into debates that are notorious for ax-grinding and mud-slinging, Pinker shows the importance of an honest acknowledgment of human nature based on science and common sense.

Science: Space-Time Cloaking (Nat Geo)

Richard A. Lovett (National Geographic News, July 11, 2011)
Fiber optics can easily bend light around objects, but an event cloak bends time, too

It's no illusion: Science has found a way to make not just objects but entire events disappear, experts say.

Magic? Material would adjust speed of light [once imagined to be constant] to hide actions, physicists say. According to new research by British physicists, it's theoretically possible to create a material that can hide an entire bank heist from human eyes and surveillance cameras. "The concepts are basically quite simple," said Paul Kinsler, a physicist at Imperial College London, who created the idea with colleagues Martin McCall and Alberto Favaro. Unlike invisibility cloaks -- some of which have been made to work at very small scales -- the event cloak would do more than bend light around an object. More

Math genius explains $1M prize refusal


ST. PETERSBURG, Russia (UPI) - Grigory Perelman, the Russian math whiz who solved a century-old problem, said he refused a $1 million prize because he knows "how to control the universe."

Perelman, 43, of St. Petersburg told the Russian daily Komsomolskaya Pravda he had no reason to accept the $1 million prize the Clay Mathematics Institute of Cambridge, Massachussetts, offered him in 2010 for proving the Poincare conjecture, RIA Novosti reported Friday.

"Emptiness is everywhere and it can be calculated, which gives us a great opportunity... I know how to control the universe. So tell me, why should I run for a million?" Perelman said. More

Electricity from light, no solar cell needed

Light-induced magnetic effect "can produce solar power without solar cells"
ANI, April 20, 2011
WASHINGTON - Newly observed magnetic effect induced by light can produce solar power making semiconductor-based solar cells [unnecessary]. According to scientists at the University of Michigan, a newly observed “dramatic and surprising” magnetic effect of light could help produce solar power without the use of solar cells. According to Stephen Rand, a professor in the Department of Electrical Engineering and Computer Science, Physics, and Applied Physics, researchers have found a way to make an “optical battery.” Light has electric and magnetic components.
