Physicists identify molecules by vibrational signatures Professor Wilson Ho, center, and graduate students Mohammad Rezaei, left, and Barry Stipe show off their "homemade" scanning tunneling microscope in a basement laboratory in Clark Hall. The instrument, enclosed in a vacuum chamber and cooled by liquid helium, is precise enough to resolve parts of molecules. Frank DiMeo/University Photography By Bill Steele What Today's Higgs Boson Discovery Really Means The boson series, in short and somewhat muddied recollection of the subject. Please do your own research if you want a fully accurate description, google and wikipedia are great places to start, cassiopea project has a video series on the standard model that explain it pretty well too. The term 'boson' is a concatenation of Bose-Einstein, representing physical properties which are very alien to what we normally observe. The matter we can see is Newtonian, meaning it follows Newton's laws of physics.

Do Sci Fi attitudes reflect our times? Congress now speaks a full grade level lower than it did in 2005. Falling from grade 11.5 to 10.6. Using the Flesch-Kincaid test that gives your kids the "reads at a 10th grade level" score, the Sunlight Foundation has measured the vocabulary used in Congressional speeches over the years and found that the level has dropped suddenly. For both parties, but particularly amongst Republican Congressmen, particularly amongst the newest batch, such as Rand Paul (3rd worst, speaks at an 8th grade level.) Indeed the entire worst ten are Republicans (eight of those are freshmen.) Nanotechnologists change color of water using magnetic fields University of California, Riverside nanotechnologists have succeeded in controlling the color of very small particles of iron oxide suspended in water simply by applying an external magnetic field to the solution. The discovery has potential to greatly improve the quality and size of electronic display screens and to enable the manufacture of products such as erasable and rewritable electronic paper and ink that can change color electromagnetically. When the strength of the magnetic field is changed, it alters the arrangement of the spherical iron oxide particles in solution, thereby modifying how light falling on the particles passes through or is deflected by the solution.In their experiments, the researchers found that by changing the strength of the magnetic field they were able to change the color of the iron oxide solution - similar to adjusting the color of a television screen image.

Researchers find what may be a new state of matter Think way back to elementary or primary school, somewhere around third-grade physical science, when you first learned about the various states of matter. At the time you were undoubtedly told that there were three states of matter: solid, liquid, and gas. Solid is where the atoms are tightly packed into some arrangement and vibrate in place; liquids have more freedom of motion and vibration, allowing them to take on any bulk shape; gas molecules had near complete freedom of motion and rarely saw another molecule. Perhaps later you learned about plasma (molecules where the electrons have been completely stripped from the nucleus) as a fourth state, but for most people their education regarding states of matter ends around there.

Integral challenges physics beyond Einstein Integral challenges physics beyond Einstein Gamma-ray burst 30 June 2011 ESA’s Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum ‘graininess’ of space must be at much smaller scales than previously predicted. Einstein’s General Theory of Relativity describes the properties of gravity and assumes that space is a smooth, continuous fabric.

The Measurement That Would Reveal The Universe As A Computer Simulation One of modern physics’ most cherished ideas is quantum chromodynamics, the theory that describes the strong nuclear force, how it binds quarks and gluons into protons and neutrons, how these form nuclei that themselves interact. This is the universe at its most fundamental. So an interesting pursuit is to simulate quantum chromodynamics on a computer to see what kind of complexity arises.

Semiconductor structure bends light 'wrong' way A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats. The new substance is in a relatively new class of materials called "metamaterials," which are made out of traditional substances, such as metals or semiconductors, arranged in very small alternating patterns that modify their collective properties. This approach enables metamaterials to manipulate light in ways that cannot be accomplished by normal materials. In the case of the straw in a glass, normal water would make the underwater portion of the straw appear to bend toward the surface. Source:

The universe is a string-net liquid New Scientist published an article about string-net theory and unification of light and electrons. The following is my modification of the article trying to make it more accurate. -- Xiao-Gang Wen The universe is a string-net liquid Eric Weinstein may have found the answer to physics' biggest problems Two years ago, a mathematician and physicist whom I've known for more than 20 years arranged to meet me in a bar in New York. What he was about to show me, he explained, were ideas that he'd been working on for the past two decades. As he took me through the equations he had been formulating I began to see emerging before my eyes potential answers for many of the major problems in physics. It was an extremely exciting, daring proposal, but also mathematically so natural that one could not but feel that it smelled right. He has spent the past two years taking me through the ins and outs of his theory and that initial feeling that I was looking at "the answer" has not waned.
