Magnetorheological fluid - nine syllables for "Huh"?

A magnetorheological (MR) fluid is a fluid that changes the way it flows in the presence of a magnetic field. [more inside]

Foxes jump in a north-easterly direction

Foxes hunt rodents in the snow by listening for their movements and leaping high to pounce on their prey. Interestingly, they hunt most successfully when they jump in a north-easterly direction - 73% of the time. Jumping in the opposite direction has a 60% success rate. Pouncing in other directions was successful only 18% of the time. This was consistent regardless of time of day, season of year and weather conditions. [more inside]

They're not available from Edmund Scientific

Later this year, geophysicist Dan Lathrop's DIY Planet Earth will be filled with liquid sodium, weigh in at 26 tons, and will be spun-up to 80mph at its equator in an effort to discover how the earth's magnetic field is generated. Currently undergoing tests, even those can be pretty impressive.

ferrofluid art

Protrude, Flow uses magnetic fluid, sound, and moving images. Affected by the sounds and spectators' voices in the exhibition place, the three-dimensional patterns of magnetic fluid transform in various ways, and are simultaneously projected on the wide screen.

The World is Bound With Secret Knots

Athanasius Kircher was the 17th century's Jesuit version of the übergeek. His scholarly attentions were drawn to egyptology, astronomy, magnetism, languages, optics, music, geology, mathematics and many many other pursuits. The "dude of wonders" invented novel machines such as the mathematical organ and magnetic clock, established one of the first museums, published about 40 academic works (with beautiful accompanying illustrations) and was globally revered as one of his time's greatest intellectuals. He is also the main link in the Voynich manuscript mystery. [MI]

The Bakken: A social history of electricity

The Bakken: A social history of electricity The Bakken is a growing center "for education and learning that furthers the understanding of the history, cultural context, and applications of electricity and magnetism in the life sciences and their benefits to contemporary society." The site includes an illustrated collection of artifacts ranging from static electricity generators and Leyden jars to Victorian therapeutic magnetic belts, and exhibitions on Mesmer and Mesmerism and Mary Shelley and Frankenstein. The institute was founded by Earl Bakken, the co-inventor of the pacemaker.

Bert Hickman has a ten inch diameter Tesla coil powered from two neon sign transformers in his screened-in (but unheated) porch, along with a device that produces magnetic fields strong enough to shrink coins. One of the byproducts of the coin-shrinking: an eight inch ball of plasma.

"Protrude, Flow"

"Protrude, Flow" A most amazing artistic endeavor - metallic filings dumped in oil to make magnetic liquid, and the fun that ensued afterwards. Make sure to check out the video as well! (from memepool)
