Time is running short. When the IPCC published its first scientific report in 1990 on the possibility of human-caused global warming, the atmospheric concentration of carbon dioxide (CO2) was 354 ppm. It is now 397 ppm and rising. In spite of Kyoto, Copenhagen, Cancun, Durban, and Doha, atmospheric CO2 continues its inexorable upward path.
The past couple of years have seen the celebration of a number of key developments in the history of physics. In 1913 Niels Bohr, perhaps the second most famous physicist of the 20th century after Einstein, published is iconic theory of the atom.
Lipids (fats and oils) have historically been thought to elevate weight and blood cholesterol and have therefore been considered to have a negative influence on the body. Foods such as full-fat milk and cheese have been avoided by many consumers for this reason. This attitude has been changing in recent years.
At the end of last year, Eli Lilly’s mega-blockbuster antidepressant Cymbalta went off patent. And Cymbalta’s generic version, known as duloxetine, rushes in the market and drives down the price, making it more affordable.

Nearly three hundred years since his death, Isaac Newton is as much a myth as a man. The mythical Newton abounds in contradictions; he is a semi-divine genius and a mad alchemist, a somber and solitary thinker and a passionate religious heretic. Myths usually have an element of truth to them but how many Newtonian varieties are true? Here are ten of the most common, debunked or confirmed by the evidence of his own private papers.

It is a safe bet that the name of Pierre Rolland rings very few bells among the British public. In 2012, Rolland, riding for Team Europcar finished in eighth place in the overall final classifications of the Tour de France whilst Sir Bradley Wiggins has since become a household name following his fantastic achievement of being the first British person ever to win the most famous cycle race in the world.

Sometimes it’s the fly in the ointment, the thing that spoils the purity of the whole picture, which leads to the big advances in science. That’s exactly what happened at a conference in Shelter Island, New York in 1947 when a group of physicists gathered to discuss the latest breakthroughs in their field which seemed at first sight to make everything more complicated.

“When you have eliminated the impossible, whatever remains, however improbable, must be the truth”. Thus Arthur Conan Doyle has Sherlock Holmes describe a crucial part of his method of solving detective cases. Sherlock Holmes often takes pride in adhering to principles of scientific reasoning.

The cosmology community is abuzz with news from the BICEP2 experiment of the discovery of primordial gravitational waves, through their signature in the cosmic microwave background. If verified, this will be a clear indication that the very young Universe underwent a period of acceleration, known as cosmic inflation.

As far as we know, the first African American woman PhD was Dr. Marie Daly in 1947. I am still searching for an earlier one. Women chemists, especially minority women chemists, have always been the underdogs in science and chemistry.

“March 8 is Women’s Day, a legal holiday,” I wrote to my mother from Moscow. “This is one of the many cute cards that is on sale now, all with flowers somewhere on them. We hope March 8 finds you well and happy, and enjoying an early spring! Alas, here it is -30° C again.”

On 11 September 2013, an unusually long and bright impact flash was observed on the Moon. Its peak luminosity was equivalent to a stellar magnitude of around 2.9. What happened? A meteorite with a mass of around 400 kg hit the lunar surface at a speed of over 61,000 kilometres per hour.
In 2013, the Nobel Prize for Physics was awarded jointly to François Englert and Peter W. Higgs for their work on what is now commonly known as the Higgs field and the Higgs boson. The existence of this fundamental particle, responsible for the creation of mass, was confirmed by the ATLAS and CMS experiments at CERN’s Large Hadron Collider in 2012.

Shopping trips now comprise fewer than 9% of all trips, down from 12.5% in 2000, according to our analysis of the Twin Cities Travel Behavior Inventories. This is consistent with other results from the American Time Use Survey. They are down by about one-third in a decade.
