Quantum mechanics is the branch of physics governing the sometimes-strange behavior of the tiny particles that make up our universe. Equations describing the quantum world are generally confined to the subatomic realm—the mathematics relevant at very small scales is not relevant at larger scales, and vice versa.
However, a surprising new discovery from a Caltech researcher suggests that the Schrödinger Equation—the fundamental equation of quantum mechanics—is remarkably useful in describing the long-term evolution of certain astronomical structures.
Researchers at Queen’s University Belfast believe they have uncovered some mysteries in how the sun is able to heat its atmosphere.
Published in a study in Nature Physics, the scientists found that magnetic waves crashing through the sun are one of the key ingredients in the heating process and thus propelling the solar wind. The findings come after scientists suggesting for years that these waves may play an important role in maintaining the sun’s super high temperatures, but only now have they been able to prove it.
A cycle has two extremes and two middles. The motion of a pendulum has two high points and one low point, which it passes through twice. The phases of the moon are a new moon, a full moon, and two quarter moons.
Newton’s great feat, which maybe is not commonly acknowledged, is he explained how there were two diurnal ocean tidal cycles each day which were obviously influenced by the moon’s cycle as it revolved (orbited) about the earth once about every 25 hours as the earth rotated about its axis with a period of 24 hours. Clearly these cycles have a period of time associated with them.
The alarms are sounding about lack of ice extent in the Bering Sea, studiously ignoring what else is happening in the Arctic.
For instance, the above image shows the last 10 days on the European side, with the Barents Sea on the right growing steadily to a new maximum. On the left, Gulf of St. Lawrence ice is retreating as usual while the Baffin Bay holds steady.
A group of American scientists was rescued from an island off Antarctica’s coast after ice prevented a U.S. Antarctic Program research vessel from reaching them.
A huge solar storm is heading for Earth, and it’s likely to hit tomorrow. Nasa spotted the solar flare releasing a coronal mass ejection earlier this week. National Oceanic and Atmospheric Administration issued a ‘G1’ storm watch. It coincides with the formation of ‘equinox cracks’ in the sun, which form around the equinoxes on March 20 and September 23 and weaken the magnetic field.
What would happen if it were proven that “fossil fuels” weren’t the result of decaying plant and animal matter, were actually created within the Earth due to simple chemistry and you could not be scared into believing that we were “running out” of oil and natural gas?
Learning can result in the increase of how much information our brains can hold, researchers have found.
Researchers at UT-Austin, the Salk Institute for Biological Studies and the University of Otago in New Zealand discovered that the capacity of a synapse, the junctions between brain cells, expand in response to learning.
“Our most recent finding found that the range of a synapse is not fixed,” said Kristen Harris, a UT neuroscience professor. “On the other hand, if you buy a flash drive, the factory determined how much info you could store; it’s at a fixed level. Our brains are not like that.”
Trapped in the rigid structure of diamonds formed deep in the Earth’s crust, scientists have discovered a form of water ice that was not previously known to occur naturally on our planet.
The finding, published Thursday in Science, represents the first detection of naturally occurring ice-VII ever found on Earth. And as sometimes happens in the scientific process, it was discovered entirely by accident.
I work hard to maintain my optimistic outlook. Wishful thinking works. The first step toward building a more healthy, peaceful, just world is to believe we can do it. So how do I deal with all the bad news about climate change? U.S. officials are rolling back regulations designed to curb global warming even as reports flood in about its scale and potential consequences.
Professor Brian Wansink is head of the Food and Brand Lab at Cornell University. The lab has had problems, some described in an article called “Spoiled Science” in the Chronicle of Higher Education early in 2017:
Four papers on which he is a co-author were found to contain statistical discrepancies. Not one or two, but roughly 150. That revelation led to further scrutiny of Wansink’s work and to the discovery of other eyebrow-raising results, questionable research practices, and apparent recycling of data in at least a dozen other papers. All of which has put the usually ebullient researcher and his influential lab on the defensive.
A new study shows that the Antarctic Ice Shelf has been thickening – in times of global warming. Logic: Global warming cannot be the driving factor for Antarctic ice shelf mass, let alone CO2.
In an expanding universe, as postulated by mainstream cosmology, the farther away we look at galaxies, the further back in time we are also looking.
Therefore, we would expect to see galactic density increase with distance, since the volume of the early universe would have been smaller such that galaxies would have been more closely packed. Astronomical observations appear to show relatively constant galactic density vs. distance, inconsistent with the concept of an expanding universe started from a Big Bang, but not inconsistent with one that has existed indefinitely in a steady state.
Abstract: The measurements of gravitational waves, γ- rays, X-rays, UV, blue light, and red light from collision of neutron stars on 17th August 2017 opened a subject of gravitational wave astronomy.
As these emissions are found similar to radioisotopes and solar emissions caused by 235uranium fission, fission is reported to be taking place during collision. Therefore, fission could be the source for gravitational waves (GW170817). Early arrival of blue light than red light is attributed to its high energy and signifies reliability of measurements.
