Geeks themselves think that the term is used for "reclaiming the geek identity as something not only meaningful, but also stylish." - for this usage, more than just glasses are needed, and so the term has a wider meaning, being applied to home fittings and objects as well as clothes. In this usage, the term "geek chic" can even be used as a positive contrast to the somewhat more negative term "geeky".
Geek chic is not to be confused with preppie fashion, which is more widely to do with a conservative image rather than geek culture. Instead, much of the geek chic image borrows from various other youth fashions such as goth, hippie, and bohemian among others, but t-shirts with geeky in-jokes seem to originate from the geeks themselves. Shirt designers who tailor to geeks offer rewards for the best ideas.
The company of has trademarked "Geek Squad" as the name of its computer repair service. Best Buy has fought the trademarks of a dozen other companies, including Geek Rescue, Rent a Geek, and . It is also fighting with Newegg over the use of "Take it from a Geek" on Newegg's website. The NBC television show "Chuck" wanted to use "Geek Squad" to describe the main characters' job. But Best Buy asked for them to change the name. So the characters on "Chuck" were called "Nerd Herd" instead.
42 (answer)
42 is the "Answer to the Ultimate Question of Life, the Universe, and Everything" in "The Hitchhiker's Guide to the Galaxy" books. It was computed by
Deep Thought, the second greatest computer ever. The descendants of Deep Thought's creators are upset by the numeric nature of the answer, not understanding what to do with it or what to tell the people who had commissioned the 7.5-million year project.
When asked to produce The Ultimate Question to go with the answer "42", Deep Thought admits it is not capable of computing that itself, but that it can help to design an even more powerful computer, which can. This new computer will incorporate living beings into the "computational matrix" and will run for ten million years. It is the planet Earth.

Northern Virginia military shootings
The Northern Virginia military shootings were several attacks by a man shooting a rifle at empty military buildings. The shots were fired in October and November 2010. Experts looked at the bullets left at the various places. They could see that all of the shots were from the same rifle.
The first shooting was aimed at the National Museum of the Marine Corps in Triangle, Virginia on October 16, 2010. Some bullets from a high-velocity rifle went through the atrium skylight. The second shooting happened on October 19, 2010 shortly before 5 a.m. Someone shot at the south side of The Pentagon in Arlington, Virginia. The bullets broke windows on the third and fourth floors. Special glass stopped the bullets from entering the building. The offices behind those windows were empty because of repairs. The Pentagon Reservation was temporarily closed because the police searched the area for evidence. The building was reopened about 5:40 a.m. The Joint Terrorism Task Force is leading the investigation into the incident. In the third shooting, the same rifle shot the Marine Corps Museum again on October 29. The same rifle was used to attack a Marine Corps recruiting center in Chantilly, Virginia on October 26.
These attacks made the organizers of the October 31, 2010 Marine Corps Marathon upgrade the safety measures. The race was run without problems. On November 3, police announced that the same rifle was used to shoot at a United States Coast Guard recruiting center in Woodbridge, Virginia on late November 1 or early November 2.
The person behind the attacks remained unknown until June 17, 2011 when Yonathan Melaku was arrested. He is a 22 year old naturalized Ethiopian immigrant and Marine Corps Reserve Lance Corporal. He was found at Arlington National Cemetery while it was closed. He was carrying spent shell casings, a notebook containing references to the Taliban and Osama bin Laden, and plastic bags filled with ammonium nitrate, a common component of homemade explosives. He also left his car parked in the woods near the Pentagon, police said. He had also been recently charged with breaking into 27 cars in suburban Washington. The investigation of the incident connected Melaku to the shootings. On June 23, 2011, he was charged with two counts of willfully injuring the property of the United States. If he is convicted of those charges, he could go to prison for 20 years. Melaku is also charged with two counts of using a firearm during a violent crime. If he is convicted of those charges, he could go to prison for the rest of his life. More charges are possible.
The Federal Bureau of Investigation is working with the Fairfax County Police, the Prince William County police and the Pentagon Force Protection Agency to investigate the case.
Molecular symmetry
Molecular symmetry is a basic idea in chemistry. It is about the symmetry of molecules. It puts molecules into groups according to their symmetry. It can predict or explain many of a molecule's chemical properties.
Chemists study symmetry to explain how crystals are made up and how chemicals react. The molecular symmetry of the reactants help predict how the product of the reaction is made up and the energy needed for the reaction.
Molecular symmetry can be studied several different ways. Group theory is the most popular idea. Group theory is also useful in studying the symmetry of molecular orbitals. This is used in the Hückel method, ligand field theory, and the Woodward–Hoffmann rules. Another idea on a larger scale is the use of crystal systems to describe crystallographic symmetry in bulk materials.
Scientists find molecular symmetry by using X-ray crystallography and other forms of spectroscopy. Spectroscopic notation is based on facts taken from molecular symmetry.
Physicist Hans Bethe used characters of point group operations in his study of ligand field theory in 1929. Eugene Wigner used group theory to explain the selection rules of atomic spectroscopy. The first character tables were compiled by László Tisza (1933), in connection to vibrational spectra. Robert Mulliken was the first to publish character tables in English (1933). E. Bright Wilson used them in 1934 to predict the symmetry of vibrational normal modes. The complete set of 32 crystallographic point groups was published in 1936 by Rosenthal and Murphy.
Mathematical group theory has been adapted to study of symmetry in molecules.
The symmetry of a molecule can be described by 5 types of symmetry elements.
Each of the five symmetry elements has a symmetry operation. People use a caret symbol (^) to talk about the operation rather than the symmetry element. So, Ĉ is the rotation of a molecule around an axis and Ê is the identity operation. A symmetry element can have more than one symmetry operation associated with it. Since C is equivalent to E, S to σ and S to "i", all symmetry operations can be classified as either proper or improper rotations.
A point group is a set of symmetry operations forming a mathematical "group", for which at least one "point" remains fixed under all operations of the group. A crystallographic point group is a point group which will work with translational symmetry in three dimensions. There are a total of 32 crystallographic point groups, 30 of which are relevant to chemistry. Scientists use Schoenflies notation to classify point groups.
Mathematics define a "group". A set of symmetry operations form a group when:
The order of a group is the number of symmetry operations for that group.
