Photonic Dipole Contours of Ferrofluid Hele-Shaw Cell (Two Magnet Non-Pole Video)
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 the two magnet version with the non-pole sides mostly f

"Right After That They Walked Out": Alice Wolfson Recalls the Origins of the CIO
John L.

Here Alice Dodge Wolfson, who was working as a stenographer in 1935, recalled her own contribution to the Lewis walkout and the creation of the CIO. Attending the October 1935 A

"I Never Met a Black Person Who Was in the Communist Party Because of the Soviet Union:" Jack O'Dell
Jack O'Dell was a union organizer, a civil rights leader, and a member of the Communist Party. His political consciousness formed in the 1940's, when the African-American community became more assertive in their efforts to improve conditions and expand civil rights. Like many blacks, including one of his role models, Paul Robeson, O'Dell was drawn to the Communist Party because of their staunch stand against racism and segregation. During the 1940's, O'Dell found a welcoming environment in the N
