Researchers have solved the problem of radio congestion by twisting radio waves into the shape of fusilli pasta.
One of the earliest lessons in science that students learn is that a ray or beam of light travels in a straight line.
Whether they know it or not, anyone who's ever gotten a speeding ticket after zooming by a radar gun has experienced the Doppler effect â€“ a measurable shift in the frequency of radiation based on the motion of an object, which in this case is your car doing 45 miles an hour in a 30-mph zone.
Researchers are devising instruments and protocols to assess the impact of nanoparticles on the environment and human health before they are sent to market.
Rogue wavesâ€”giant waves that spring up suddenly and tower over the seas around themâ€”have inspired physicists to look for an analogue in light.
Research at the University of Liverpool has shown it is possible to develop an â€˜invisibility cloakâ€™ to protect buildings from earthquakes.
By Roh, Jung-Sim Chi, Yong-Seung; Kang, Tae Jin; Nam, Sang-wook Abstract The growth of the electronic industry and the widespread use of electronic equipment in communications, computations, automations, biomedicine, space, and other purposes have led to many electromagnetic interference (EMI) problems as systems operate in close proximity.
Working at both the Advanced Light Source (ALS) at the U.S. Department of Energyâ€™s Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg, Germany, an international group of scientists has produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made, thousands of times more efficiently than previous x-ray-holographic methods.
A hundred years ago, we took the first steps in recognising, at the level of elementary physical events, the dual character of nature that had been postulated in natural philosophy. Albert Einstein was the first who saw Max Planckâ€™s quantum hypothesis leading to this dual character. Einstein suggested the photon have an electromagnetic wave character, although photons had previously been considered as particles. That was the quintessence of his work on the photoelectric effect. Later...
Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...
Doppler Effect -- The Doppler effect is the apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves. For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from both motion of the source and motion of the observer. Each of these effects is analyzed...
