Photonic Dipole Contours of Ferrofluid Hele-Shaw Cell (Off Axis Lighting)
This investigation describes and demonstrates a novel technique for the visualization of magnetic fields. Two ferrofluid Hele-Shaw cells have been constructed to facilitate the imaging of magnetic field lines. We deduce that magnetically induced photonic band gap arrays similar to electrostatic liquid crystal operation are responsible for the photographed images and seek to mathematically prove the images are of exact dipole nature. This is off axis lighting version, per figure 9 of the paper. h
Kepler - A Search for Habitable Planets
The Kepler Mission is part of NASA's Discovery Program, a series of lower-cost, highly focused planetary science investigations designed to enhance understanding of the solar system. This webpage describes how Kepler, scheduled for launch in 2006, will use a unique spaceborne telescope specifically designed to search for Earth-like planets around stars beyond our solar system. It will look for the "transit" signature of planets. A transit occurs each time a planet crosses the line-of-sight betwe

Learn with Pictures and Video S4 #18 - Japanese Expressions That Help with the Housework 2
Having your own place in Japan has been amazing! You have so much freedom, and it’s quiet when you need peace to study Japanese. The worst thing about having your own place is keeping it nice and tidy. Deciding that a little clutter doesn’t interrupt your Japanese practice, you’ve put the dusting and the dishes [...]
Economic Update on WBAI 99.5FM April 23rd - Guest Costas Panayotakis
Description not set
Black holes are formed when extremely large star dies. When a star dies, it first expands, then contracts. Large stars contract until their atoms collapse, pulling the electrons into the nucleus. The immense strength of the gravitational force of a black hole pulls all nearby matter in, even light (which has mass). (02:28)
Soccer Move - The Jing

Using Nature to Grow Batteries
Inspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, she's produced viruses that can construct powerful new batteries, clean hydrogen fuels and record-breaking solar cells. At TEDxCaltech, she shows us how it's done. (10:26)

"In School Days" by John Greenleaf Whittier (poetry reading)
An American poem. The British find American sentimentality and sincerity hard to bear - just as Americans find British irony and dry humour baffling. The picture of the Californian School House looks as though it was taken in about 1930 - it comes from this site: http://cerritos.org/community/history-of-the-region The Schoolroom was painted by William Bromley Still sits the school-house by the road, A ragged beggar sleeping; Around it still the sumachs grow, And blackberry-vines are creep
"Ode to New York" by Byron Rufus Newton (poetry reading)
Sometimes called "Owed to New York". Byron wrote this satirical poem when he was a reporter of the New York Herald in 1906. Thirteen years later, he was appointed Collector of Customs for the Port of New York. Then folk took exception to this poem and demanded his resignation. He was obliged to issue a statement to the effect that he was "just kidding". He probably figured out a defence that everything he said was true wasn't going to get him off the hook. Satire stops being funny at the exact
