Many are troubled by dark energy
. I will tell you first why dark energy is really crazy. Then I tell you that the crazy part is not actually the problem of dark energy, but one of basic general relativity. Many educated people are proudly critical of dark stuff, but when it comes to relativity, they do not want to be found hanging out in the crack-pot corner. In other words, my post is directed at the guys who go: “I know about relativity and agree it is more or less fine what those cosmologists did then, but this dark stuff now is going too far! Stop the wild guessing and go back to doing proper science.”
Stupid physicists, they are doomed. Spending their whole lives searching for a theory of everything, not knowing that some eighty years ago this was proven to be logically impossible.
The internet is full with sentiments like the above
. Many such posts refer to Stephen Hawking's 2002 Dirac lecture Gödel and the End of Physics
The arxiv is featuring a new paper by Darien Wood
, member and spokesperson of the DZERO experiment and a distinguished physicist with lots of experience in hadron collider physics. The paper is titled "The Physics Case for Extended Tevatron Running
" and it is an explanation of the benefits that a Run III until 2014 will bring to our knowledge of high-energy physics.
The most recent issue of symmetry
magazine has a feature titled, "When Muons Collide
," by Leah Hesla. [Full disclosure: I have also written for symmetry
.] The article lays out the need for a muon collider as well as theoretical plans for building one.
Can plasma be beautiful? Surely, anything can, but physicists are luckier than most because when they probe the mysteries of plasma, the fourth state of matter, they often discover phenomena of striking beauty.
Plasmas support a large variety of waves, some familiar to all such as light and sound waves, but a great many exist nowhere else and one of the fundamental waves in magnetized plasma is the shear Alfvén wave, named after Nobel Prize winning scientist Hannes Alfvén, who predicted their existence.
<![endif]-->Microwaves are a low frequency light, at least compared to visible light, say, or ionizing radiation like gamma rays. Thus, microwaves are quite harmless. A microwave oven baths the food in an oscillating electro-magnetic field. Molecules with permanent electrical dipole moments wiggle in the field and thus heat up the food.
As beautiful as they get, or even more so. It is hard to express the beauty of the event that the CMS collaboration published today
. CMS, which stands for "compact muon solenoid", is one of the two main detectors operating at the CERN Large Hadron Collider (the other is ATLAS). The duo is seeking evidence for the Higgs boson, the only elementary particle predicted by the Standard Model that still awaits to be discovered.
Giorgio Chiarelli is a particle physicist. His research activity has been based largely at the Fermi laboratory near Chicago, US, at the CDF experiment. In 1994-96 he actively participated in the discovery of the top quark and in the first measurements of that particle's properties. Later, after directing the construction of a part of the new CDF detector, he moved its research interests toward the search for the Higgs boson. Currently he is a INFN research director in Pisa, where he leads the CDF-Pisa group. In the most recent years he dealt with problems connected with the communication of science.
The ATLAS collaboration has just released an important study
of the sensitivity to a standard model Higgs boson. For the first time precise predictions are made for LHC running at a centre-of-mass energy of 7 TeV (but also 8 and 9 TeV are considered, given the possibility that next year the energy is bumped up a bit), and for most of the sensitive channels together.
The public document is long and detailed, and I have no time to discuss its intricacies with you here, nor do I believe that you would actually want me to. But I do want to discuss one of the most significant figures in the note. It is shown below.
Special Guest Post From A Far Boundary Of Our Universe
By Richard P. Flatman
"I call our world Flatland, not because we call it so, but to make its nature clearer to you, my happy readers, who are privileged to live in Space."
This is how my great-grandfather, Albert Square, started his memoirs. Memoirs he wrote in solitary confinement. Years later he died, still imprisoned and alone, and unaware that his ideas slowly but steadily started to change the views and imagination, not only of his fellow Flatlanders, but also of you Spacelanders.*
