Two visual demonstrations of levitation, each using known physics properties: 1. Using sound waves to levitate particles [REFERENCE: “Three-dimensional Mid-air Acoustic Manipulation by Ultrasonic Phased Arrays,” Yoichi Ochiai, Takayuki Hoshi, Jun Rekimoto, (2013) arXiv:1312.4006.. Thanks to @BetsytheDevine for bringing this to our attention.]: 2. The Ig Nobel Prize-winning levitation of a frog, using magnets [REFERENCE: “Of […]

The scientist who says he rose up against crime
Prof John Hagelin‘s decision not to run against Mitt Romney and Barack Obama left this year’s US presidential race without a major candidate who is a scientist and who acknowledges – publicly – his ability to both counteract gravity and prevent crime. Two decades ago, Hagelin and a team of fellow scientists performed a bold experiment. […]
“No one had tried such a silly thing before” — Geim
With this idea in mind and, allegedly, on a Friday night, I poured water inside the lab’s electromagnet when it was at its maximum power. Pouring water in one’s equipment is certainly not a standard scientific approach, and I cannot recall why I behaved so ‘unprofessionally’. Apparently, no one had tried such a silly thing […]
Mice Levitated in Lab
Ig Nobel Prize-winningwork of Andre Geim and Michael Berry, Yuanming Liu, Da-Ming Zhu, Donald M. Strayer and Ulf E. Israelsson have used magnets to levitate mice. Their study in the journal Advances in Space Research tells all, or at least much, or what they did. Called “Magnetic levitation of large water droplets and mice“, it […]
More Leffler, much more
The unstoppable Dr. David Robert Leffler, who devised a Theory of Pretty Much Everything, has again written us in hopes of saving the world. This time he mentions a very few of his recent publications. He explains: I hope things are going well for you since we last communciated and that you have a joyous […]
