Latest Introductory physics Stories
JILA researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round—research with major implications for future scientific understanding of the universe.
Magnets have fascinated mankind for millenia. From the Greek philosophers to scientists of the modern era, which saw the rise of quantum mechanics, magnets have been pondered and investigated.
Control of the Magnetic Moment of Single Atoms Is the Key to Compact Data Memories and Quantum Computers
Despite recent claims challenging Heisenberg's nearly century-old uncertainty principle, an international team of researchers has provided a formal proof of the theory.
Magnetic molecules are regarded as promising functional units for the future of information processing.
Physics students have determined what energy it would take in order for the fictional Star Trek character Scotty to beam up Captain Kirk.
A new study reveals that a quantum effect known to be the key in stellar physics may also be the missing piece in space chemistry.
The most efficient ways of storing energy is within electric and magnetic fields. And as the world proceeds to develop ever more efficient and “green” energy solutions, understanding the nature of these fields and how the energy propagates is essential.

General Relativity -- General Relativity is the common name for the theory of gravitation published by Albert Einstein in 1915. According to general relativity the force of gravity is a manifestation of the local geometry of spacetime. Although the modern theory is due to Einstein, its origins go back to the axioms of Euclidean geometry and the many attempts over the centuries to prove Euclid's fifth postulate, that parallel lines remain always equidistant, culminating with the...
Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...
