Theoretical physicist David Kaplan discusses Particle Fever and the Higgs Boson

submitted by: nsf

Particle Fever, a documentary film about the Large Hadron Collider (LHC) and the Higgs boson, has caught the attention of scientists and non-scientists alike. This interview with David Kaplan, a Johns Hopkins University physics professor and the film's producer, provides a little behind-the-scenes look at life as a physicist and some decision making involved in making Particle Fever.

Magnetic Cracked Pot

submitted by: SirZerp
The magnetic fields of a cracked pot. Note - the blue ring in the center is from having two different magnets; the bottom volume is like a large ring magnet and the top is like a cylinder magnet. The interaction between the two, top and bottom, produces the blue ring eddy of flux. Also a capacitor with horizontal plates has the same field values as a vertical aligned magnet. In other words, you could design a capacitor that has the same field as the object in the video, but it would be...

Magnetic Statue of Liberty

This video was made about a week before the 'Magnetic Thinker' video using the same techniques. Mainly I can model any form that can be saved as a STL file, which used in 3d printing. Each STL object in a scene can have different magnetic alignments.

Optical Stern-Gerlach with a Ferrofluid Cell

submitted by: SirZerp

Using a camera adjacent to an incandescent lamp with a polarizing filter that is supplying light at a 45 degree incidence angle to the ferrofluid cell. Basically, using a bright lamp instead of a camera flash. If you look, you can see the image of the camera reflected in the background. On the other side of the ferrofluid cell is a single rotating magnet, profile view with a north and south poles adjacent to the cell. Only the magnet moves, everything else is fixed in place.
