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.

Magnetic Thinker

If the statue was made of Neodymium and magnetized thru the vertical axis, the colors show the energy levels and the white dots show the magnetic 'B' field lines.

CES 2014: Barobo robots teach children algebra

submitted by: nsf

At the Consumer Electronics Show, CES 14, Barobo, Inc. showed the NSF their robot that helps teach children algebra in a completely new way. By taking algebra off the page and into the physical world, Barobo aims to inspire a new generation of mathematicians.

History of Medicine. Plague and Vampirism in the Middle Ages.

The Nachzehrer would be a special kind of vampire who lives in a constant state of numbness in his grave, without understanding what is happening around and just like a child, chewing spasmodically his dress. Martin Böhm wrote in 1601: "We have seen in times of the plague how dead people especially women - who have died of the plague make smacking noises in their graves, like a pig that is eating, and that while this smacking is going on the plague becomes much worse, usually in the...
