As the excitement surrounding the recent discovery of the long-sought Higgs boson fades, evidence is building to support the notion that there may be more than one type of Higgs boson. Thought to imbue subatomic particles with mass via the Higgs field, the Higgs boson has been of particular interest...

 
 

Quantum Entanglement Experiment to Take Place Aboard the International Space Station

Quantum Entanglement Experiment to Take Place Aboard the International Space Station

Research on quantum entanglement is posed to make yet another leap forward as European researchers outline an experiment involving the International Space Station. Quantum entanglement, what Einstein termed “spooky action over a distance,” has remained puzzling to physicists since it was first predicted in the early years of quantum theory...

The Higgs boson, first theorized in 1964 by Peter Higgs of the University of Edinburgh, is an elementary particle that explains why some particles have mass and others do not (1). The way in which the Higgs boson imbues elementary particles with mass can be described metaphorically with a snowy...

A team of geologists from the University of Oslo in Norway recently found evidence of a lost subcontinent under the Indian Ocean. The submerged landmass allegedly sunk during the break-up of the prehistoric supercontinent Rodinia, which once joined India and Madagascar 85 million years ago (1). Geologist Bjørn Jamtveit and...

On February 15, 2013, a small asteroid named “2012 DA14” is expected to fly past the Earth. The asteroid weighs approximately 130,000 metric tons, has a rough diameter of 45 meters, and has a speed eight times that of a high-powered rifle. If it were to collide with the Earth,...

In the fourth Science Pub of the academic year, Dr. Ryan Hickox of Dartmouth’s Department of Physics and Astronomy and Dr. Jenny Greene of Princeton University’s Department of Astrophysical Sciences led a discussion on black holes. Dr. Hickox explained that black holes are defined by their powerful gravitational forces. Black...

Metallacycle-Mediated Cross-Coupling

Metallacycle-Mediated Cross-Coupling

Glenn Micalizio, an associate professor in the chemistry department at the Scripps Research Institute in Florida, gave a presentation last Tuesday titled, “Metallacycle-Mediated Cross-Coupling: Reaction Development and Application in Stereoselective Synthesis,” which summarized his recent research which substantially expands of the scope and applications of a developing class of synthetic reactions aimed at selective carbon—carbon bond formation.

 
 

Dartmouth Physics: Ernest Fox Nichols

Ernest Fox Nichols served as President of Dartmouth College from 1909 to 1916. Prior to his appointment, he was a Professor of Physics from 1898 to 1903. He would later become President of MIT.

On Friday October 5th professor Ralph Gibson lectured on former Dartmouth President Ernest Fox Nichols as a part of the series of lectures for the American Physical Society’s designation of the Wilder Physics building as a historical site. Gibson began the seminar with the Crookes radiometer. The device is an encased...
