To provoke more interest and excitement for students and lecturers alike, a professor from Florida Atlantic University s College of Engineering and Computer Science is spicing up the study of complex differential mathematical equations using relevant history of algebra. In a paper published in the
Journal of Humanistic Mathematics, Isaac Elishakoff, Ph.D., provides a refreshing perspective and a special shout out to Stephen Colbert, comedian and host of CBS s The Late Show with Stephen Colbert. His motivation? Colbert previously referred to mathematical equations as the devil s sentences and an unnatural commingling of letters and numbers - with the worst being the quadratic equation - an infernal salad of numbe ....

3D model shows off the insides of a giant permafrost crater

Researchers from the Oil and Gas Research Institute of the Russian Academy of Sciences and their Skoltech colleagues have surveyed the newest known 30-meter deep gas blowout crater on the Yamal Peninsula, which formed in the summer of 2020. The paper was published in the journal
Geosciences.
Giant craters in the Russian Arctic, thought to be the remnants of powerful gas blowouts, first attracted worldwide attention in 2014, when the 20 to 40-meter wide Yamal Crater was found quite close to the Bovanenkovo gas field. The prevailing hypothesis is that these craters are formed after gas is accumulated in cavities in the upper layers of permafrost, and increasing pressure ultimately unleashes an explosive force. Most of these craters are rather short-lived as they apparently quickly fill with water over several years and turn into small lakes. As of now, there are some 20 known and studied craters. ....

Comet or asteroid: What killed the dinosaurs and where did it come from?

Credit: Credit not required. This is a public domain image.
It forever changed history when it crashed into Earth about 66 million years ago.
The Chicxulub impactor, as it s known, left behind a crater off the coast of Mexico that spans 93 miles and runs 12 miles deep. Its devastating impact brought the reign of the dinosaurs to an abrupt and calamitous end by triggering their sudden mass extinction, along with the end of almost three-quarters of the plant and animal species living on Earth.
The enduring puzzle: Where did the asteroid or comet originate, and how did it come to strike Earth? Now, a pair of researchers at the Center for Astrophysics | Harvard & Smithsonian believe they have the answer. ....

Corn belt farmland has lost a third of its carbon-rich soil

E-Mail
More than one-third of the Corn Belt in the Midwest - nearly 30 million acres - has completely lost its carbon-rich topsoil, according to University of Massachusetts Amherst research that indicates the U.S. Department of Agriculture has significantly underestimated the true magnitude of farmland erosion.
In a paper published in the
Proceedings of the National Academy of Sciences, researchers led by UMass Amherst graduate student Evan Thaler, along with professors Isaac Larsen and Qian Yu in the department of geosciences, developed a method using satellite imagery to map areas in agricultural fields in the Corn Belt of the Midwestern U.S. that have no remaining A-horizon soil. The A-horizon is the upper portion of the soil that is rich in organic matter, which is critical for plant growth because of its water and nutrient retention properties. The researchers then used high-resolution elevation data to extrapolate the satellite measurements across the Corn Bel ....

Scientists discovered new physical effects important for the ITER reactor operation

Credit: Peter the Great St.Petersburg Polytechnic University
The energy of the future lies in the area of the controlled thermonuclear fusion. The scientific group from Peter the Great St.Petersburg Polytechnic University (SPbPU), headed by Professor Vladimir Rozhansky, is directly involved in the establishment of the world s largest experimental thermonuclear reactor ITER. Researchers discovered new effects, which affect the energy flow in the reactor. The theoretical predictions were confirmed by the experiments on two tokamaks. The research results were published in the scientific journal
Plasma Physics and Controlled Fusion .
The scientific group of Polytechnic University is engaged in modeling of the edge plasma. The researchers aim to identify how and what types of impurities to enter the reactor, and how the power coming from the central zone to be redistributed, and so on. Scientists of SPbPU developed SOLPS-ITER transport code. Currently it is a ....
