A possible Higgs boson of cancer and steps to give natural biodiversity a fighting chance will be among the topics Princeton University researchers will discuss during the 2013 AAAS annual meeting.
According to two American physicists, the world’s most famous and elegant equation, E = mc2 may have its origins in an obscure Austrian physicist named Friedrich Hasenöhrl.
A popular theory that emphasizes dark energy as a contributor to the acceleration of the universe’s expansion does not fit newly obtained data with regards to one fundamental constant – the proton to electron mass ration – claims a University of Arizona astronomy professor.
Scientists from University of Newcastle say that the platinum-based kilogram standard has been putting on weight over the years, adding tens of micrograms of hydrocarbon "pollution" every year.
The Woodward effect is one of many effects that can be derived from the framework of general relativity. The mathematics can be somewhat opaque and so it can be difficult to determine if the resulting effect is a physical, or purely mathematical construct.
A team of scientists has found that in different animals, the two traits of brain size and body size are driven by different evolutionary mechanisms.
Association of Catholic lawyers honors four recipients with St.
Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...
Gravitational Lens -- A gravitational lens is formed when the light from a very distant, bright object (such as a quasar) is "bent" around a massive object (such as a massive galaxy) between the bright object and the viewer. The process is known as gravitational lensing, and was one of the predictions made by Einstein's general relativity. Description In a gravitational lens, the gravity from the massive object bends light as a lens might. As a result, the path of the light from a...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
