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 .

"This is a story of how the impossible became possible. How, for centuries, scientists were absolutely sure that solids (as well as decorative patterns like tiling and quilts) could only have certain symmetries - such as square, hexagonal and triangular - and that most symmetries, including five-fold symmetry in the plane and icosahedral symmetry in three dimensions (the symmetry of a soccer ball), were strictly forbidden. Then, about twenty years ago, a new kind of pattern, known as a "quasicrystal," was envisaged that shatters the symmetry restrictions and allows for an infinite number of new patterns and structures that had never been seen before, suggesting a whole new class of materials...."
Physicist Paul J. Steinhardt delivers a fascinating lecture (WMV) on tilings and quasicrystals. However, it turns out science was beaten to the punch: a recent paper (PDF) suggests Islamic architecture developed similar tilings centuries earlier.

It's a class specifically for non-physics majors and teaches the real world results of the sometimes impenetrable math involved in university physics. After every lecture, you should come away with the feeling that what was just covered is important for every world leader to know. I just sat through the entire hour and 13 minute nukes lecture and was riveted.

But Professor Eugene Polzik and his team at the Niels Bohr Institute at Copenhagen University in Denmark have made a breakthrough by using both light and matter.

For most people, it probably wasn't chalkboards full of endless physics equations that got them interested in the sciences, but rather the crazy, cooky and awe-inspiring professors who do dramatic and unique demonstrations to get students interested. What makes a good teacher or professor? Is this teacher really reckless or is it a legit demonstration that benefits students?

Widely regarded as the first modern chemist (his book The Sceptical Chymist is perhaps the founding text of chemistry as a science), he was also an alchemist and made significant contributions in physics (for example Boyle's law) and physiology.

Nova Science Now recently ran a segment on lightning (quicktime, real, and windows video here). I figured that subject was over and done with shortly after Franklin flew a kite, but it turns out we don't really know exactly what causes a bolt to start. The coolest part of the segment was these researchers in Florida. Scientists know how hard it was to observe, monitor, and even find lightning bolts, so these guys built their own rig. High-powered model rockets attached to a couple thousand feet of wire, which is grounded to larger metal structures on the ground. The result? Shoot a rocket into a storm cloud and you get instant lightning you can count on, measure, and control.

Does dark matter exist? Dark matter has been suggested as a solution to the galaxy rotation problem where individual stars don't seem to rotate the way Newton's laws would predict. Now, some scientists are saying that observations fit with Einstein's general relativity, without any dark matter needed. I just find it amazing that no one has tried this yet.

e=mc^2*100 It has been a hundred years since the date that Einstein's famous equation was first published, the last of his four annus mirabilis papers of 1905. In celebration, you can hear Einstein explain his formula (or listen to any of 10 other famous physicists do the same), or read an interesting site in celebration of his life and works, or, if physics isn't your thing, peruse his views on religion, or his exchange with Freud about war, or take a look at hundreds of his original manuscripts.

Jim Loy's Mathematics Page is (among other things) a collection of interesting theorems (like Napoleon's Triangle theorem), thoughtful discussions of both simple and complex math, and geometric constructions (my personal favorite); the latter of which contains surprisingly-complex discussions on the trisection of angles, or the drawing of regular pentagons.
Similarly enthralling are the pages on Billiards (and the physics of), Astronomy (and the savants of), and Physics (and the Phlogiston Theory of), all of which are rife with illustrations and diagrams. See the homepage for much more.

The Logic of Diversity "A new book, The Wisdom of Crowds [..:] by The New Yorker columnist James Surowiecki, has recently popularized the idea that groups can, in some ways, be smarter than their members, which is superficially similar to Page's results. While Surowiecki gives many examples of what one might call collective cognition, where groups out-perform isolated individuals, he really has only one explanation for this phenomenon, based on one of his examples: jelly beans [...] averaging together many independent, unbiased guesses gives a result that is probably closer to the truth than any one guess. While true — it's the central limit theorem of statistics — it's far from being the only way in which diversity can be beneficial in problem solving." (Three-Toed Sloth)

String Theory Turns 20 - first posited in 1984 as an explanation for the strong force, String Theory turns 20 this year. While some physicists celebrate, others are concerned that string theory isn't coming close to being a theory of everything as many had hoped. While it does reconcile quantum mechanics with Special Relativity, there is currently no mathematical proof for String Theory. Even more troubling, rather than providing one solid explanation for the universe, the many dimensions of string theory offer 10^100 different possible results.

Does relativity have any practical significance? In fact, relativity had to be taken into account by the designers of the Global Positioning System. The GPS satellites are affected both by special relativity (since the satellites are moving, clocks aboard them appear to run slower as seen from the ground), and by general relativity (since the satellites are farther away from the mass of the earth, clocks appear to run faster as seen from the ground). The net effect of both is that clocks aboard GPS satellites would gain 38 microseconds per day relative to the ground, if relativistic effects were not corrected for--a figure which can be confirmed by using Google calculator.

The cable clock. This clocks tells time, just like any other clock, but the movement of the hands is hypnotic and beautiful. To physicists, time is defined by quantum mechanics. A photon with energy h (Planck's constant) behaves as though it were oscillating once per second. For Philosphers, time is less concrete, and they love to talk about it. Western society lives by the clock - does it make a difference if this is the kind of clock that you live by? After all, everyone knows that time is money. If you have to be a clock watcher, does it help if the clock is as calming as the Cable Clock is?

Stephen Wolfram has finished his book, "A New Kind of Science," which purpotedly is being espoused as a paradigm shift in many fields. But, I'm starting to see a very reductionistic attitude in many of the main theorists of complextity theory and emergent phenomena. Is the idea that the Universe is in lines of code a phallus-extension/masculine overdriven idea? Isn't math a man made mapping and can the Universe be reduced to an equation by a man? Still this book is going to be groundbreaking. Read the following exceperpt from the wired.com article:
q: "I've got to ask you," I say. "How long do you envision this rule of the universe to be?"
w: "I'm guessing it's really very short."
q: "Like how long?"
w: "I don't know. In Mathematica, for example, perhaps three, four lines of code."

I usually wouldn't post something that I found through the office "humor" mailing list, but this just seemed very MetaFilterable. Physics geeks especially take note.

Reading through Physics Today (as I'm wont to do on occasion) I came across this absolutely enthralling article on Wolfgang Pauli of whom I've never heard. Truly an admirable specimen among Physicus Intellectus. Also, it behooves me to mention "A Remembrance of Pauli in 1950."

"The Standard Model" of the universe takes a hit.
Score one for string theorists. Scientists at the Brookhaven National Laboratory appear to have discovered a new type of subatomic particle that would disprove the currently accepted model for the nature of space and matter.

How things work. Yes I know there's a plethora of physics-related 'how things work' websites out there, but I got absorbed in this one for a long time (run by physics prof Louis Bloomfield). Started with my wondering: "Why do colors fade in sunlight?" The first page though has an interesting bit (with video) about explosive superheated water. Don't try this at home.

Speed of light broken. But it may be awhile before we can harness it for anything useful. Fascinating, nonetheless.

Can the speed of light be broken? It's not 1 April, so this actually might be true. It'll be interesting to see the paper in Nature, if and when.
