System and method for creating exalted video games and virtual realities. This patent application, describing a new genre of "exalted video games," starts simple -- with a woman quoting Lenin -- and spirals out into a rambling tome on arts and economics over the course of 100 pages, from Aristotle to Clint Eastwood. It's easy to write off physicist/poet/entrepreneur Dr. Elliot McGuckin as a standard Internet crackpot -- except that he's also a professor at Pepperdine University, received a $125,000 grant from the Kaufmann Foundation, and teaches a class that was written up in the NYT.

Steam engine. Henry was first. Steam powered trains soon followed. Steam powered shovels, tractors, and rollers. Think technology has made steam obsolete? Not yet.
Pascal Boyer explores the field of crackpottery in his article How I found glaring errors in Einstein's calculations. "For some time now, I have been an avid reader and collector of webpages created by crackpot physicists, those marginal self-styled scientists whose foundational, generally revolutionary work is sadly ignored by most established scientists. These are the great heroes, at least in their own eyes, of alternative science." [more inside]
Solar activity normally follows an 11-year cycle. The new cycle was originally predicted to start in early 2008, but despite a few sunspots appearing last year, the Sun still features a remarkable lack of activity - the deepest minimum since 1913. However, NASA's STEREO mission has seen indications that activity is increasing again, in the form of a coronal mass ejection (video [.mov, 3.3 Mb]), with an accompanying radio burst.

"It doubtless seems highly paradoxical to assert that Time is unreal, and that all statements which involve its reality are erroneous. ... I believe that time is unreal. But I do so for reasons which are not, I think, employed by any of the philosophers whom I have mentioned, and I propose to explain my reasons in this paper." ~McTaggart, The Unreality of Time, 1908. (Bonus: The Kant Song.)
On Truth and Reality. Despite several thousand years of failure to correctly understand physical reality (hence the current postmodern view that this is impossible) it is actually very simple to work out how matter exists and moves about in Space. The rules of Science (Occam's Razor / Simplicity) and Metaphysics (Dynamic Unity of Reality) require that reality be described from only one single source existing, as Leibniz wrote: "because of the interconnection of all things with one another."

Phriday Physics Phun! What is the force Superman exerts to stop a plane from crashing into the ground, or the speed and mass of Vince Vaughn's winning Dodgeball shot? What's the force exerted by a Dominique Wilkins windmill slam dunk, or the speed of a retired Charles Barkley? What's the frequency of a cat's purr? ...the mass of a snowflake? ...the pressure inside a can of soda? ..the reaction time of the human fingertip?

"...the best place to hide bulls**t is in a refereed journal that’s not open-access!" The math-physics blog n-category cafe digs into the curious case of M.S. El Naschie. El Naschie is editor-in-chief of the journal Chaos, Solitons, and Fractals, published by the well-respected scientific publisher Elsevier and sold to academic libraries for US$4,520 a year. The problem? El Naschie has published 322 of his own papers in the journal -- papers that John Baez (of "This Week's Finds in Mathematical Physics" and "The Crackpot Index") describes as "vague, dreamlike imagery," "undisciplined numerology larded with impressive buzzwords," and "total baloney." Is El Naschie a reverse Sokal? Or a Markov process for producing random publishable papers? One thing's for sure -- he knows how to cure cancer.
The Science of Scent. An entertaining and enlightening TED talk by biophysicist Luca Turin.
A math professor was explaining a particularly complicated calculus concept to his class when a frustrated pre-med student interrupts him. "Why do we have to learn this stuff?" the pre-med blurts out. The professor pauses, and answers matter-of-factly: "Because math saves lives." "How?" demanded the student. "How on Earth does calculus save lives?" "Because," replied the professor, "it keeps certain people out of medical school."
The DiVincenzo Code [youtube trailer, geekery].

Anathem, Neal Stephenson's new book, is stupendous, possibly his best. But his acknowledgments page (summarized in the print version and as expansive as ever on the Internet Reticulum) might be even more interesting, and poignant, especially as an introduction to the niftiest piece of metaphysics in the book: the quantum effects (PDFs) of consciousness among many worlds.

The ALICE Collaboration is building a dedicated heavy-ion detector to exploit the unique physics potential of nucleus-nucleus interactions at LHC energies. The aim is to study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected. This website aims both at introducing non-initiates to the field of physics covered by ALICE and at providing regular information on the evolution of the experiment, with detailed reports of its results and analysis.

Anything but clear. It is well known that panes of stained glass in old European churches are thicker at the bottom because glass is a slow-moving liquid that flows downward over centuries. Well known, yes, but long known to be wrong. Scientists still disagree about the nature of glass, and researchers continue to try to understand its dual personality . [more inside]
