A Lancaster physicist has proposed a radical solution to the question of how a charged particle, such as an electron, responded to its own electromagnetic field.

This question has challenged for over 100 years but mathematical physicist Dr. Jonathan Gratus has suggested an alternative approach—published in the Journal of Physics A: Mathematical and Theoretical with controversial implications.

It is well established that if a point charge accelerates it produces . This has both energy and momentum, which must come from somewhere. It is usually assumed that they come from the energy and momentum of the charged particle, damping the motion.

It could hardly be more complicated: tiny particles whir around wildly with extremely high energy, countless interactions occur in the tangled mess of quantum particles, and this results in a state of matter known as “quark-gluon plasma”. Immediately after the Big Bang, the entire universe was in this state; today it is produced by high-energy atomic nucleus collisions, for example at CERN.

Such processes can only be studied using high-performance computers and highly complex computer simulations whose results are difficult to evaluate. Therefore, using artificial intelligence or machine learning for this purpose seems like an obvious idea. Ordinary machine-learning algorithms, however, are not suitable for this task. The mathematical properties of particle physics require a very special structure of neural networks. At TU Wien (Vienna), it has now been shown how neural networks can be successfully used for these challenging tasks in particle physics.

Circa 2019

Annually for three years, The Lemelson Foundation will give $100 awards to outstanding inventors in up to 270 Society Affiliate Fairs with middle school participants around the country. The prize was specially created to reward young people whose projects exemplify the ideals of inventive thinking by identifying a challenge in their community and creating solutions that will improve lives.

Invasive algae are often found in bodies of water such as lakes and ponds, but can it be used as paper? Seventh-graders, Wyatt Vick and Charley Clyne, from Zane Trace Middle School in Chillicothe, Ohio, set out to answer that question with their project, “Algae Paper,” eventually earning them the Lemelson Early Inventor Prize.

The idea to investigate algae as a possible paper source came to Wyatt and Charley one day while fishing. “The water level had gone down and we saw dry algae around the edges of the pond—it resembled paper. I could even fold an origami crane out of it,” said Wyatt. “There have been a few studies about the use of algae as paper, but most of what we found was about using red algae specifically for paper products, but they performed poorly in tests.”

Roughly 13.8 billion years ago, our Universe was born in a massive explosion that gave rise to the first subatomic particles and the laws of physics as we know them. About 370,000 years later, hydrogen had formed, the building block of stars, which fuse hydrogen and helium in their interiors to create all the heavier elements. While hydrogen remains the most pervasive element in the Universe, it can be difficult to detect individual clouds of hydrogen gas in the interstellar medium (ISM).

This makes it difficult to research the early phases of star formation, which would offer clues about the evolution of galaxies and the cosmos. An international team led by astronomers from the Max Planck Institute of Astronomy (MPIA) recently noticed a massive filament of atomic hydrogen gas in our galaxy. This structure, named “Maggie,” is located about 55,000 light-years away (on the other side of the Milky Way) and is one of the longest structures ever observed in our galaxy.

The study that describes their findings, which recently appeared in the journal Astronomy & Astrophysics, was led by Jonas Syed, a Ph.D. student at the MPIA. He was joined by researchers from the University of Vienna, the Harvard-Smithsonian Center for Astrophysics (CfA.

Tesla appears to have finally agreed to walk back one feature of its controversial yoke steering wheel, as it will now provide a regular horn.

When Tesla unveiled the new Model S with the “yoke” butterfly steering wheel, it was controversial. Some were worried about the actual shape of the wheel being problematic, while others were concerned about the lack of drive stalk to choose the drive mode.

As for the former, we thought that the automaker wouldn’t risk bringing the controversial yoke steering wheel to market without a nonlinear steering curve enabled by a steer-by-wire system – especially knowing that Tesla has been developing a steer-by-wire system.

“Penske Truck Leasing and National Grid are among the first companies adding preproduction E-Transit vans to their fleets for a variety of uses, including testing the BlueOval™ Charge Network, America’s largest public charging network, plus depot fleet charging tools that monitor and help manage energy usage,” Ford explained.

Maybe The US Postal Service Will Electrify After All

That brings us to the US Postal Service, owner of a fleet of 231,541 vehicles of various types. USPS expects to roll up to 165,000 new vehicles into the fleet under a 10-year contract signed last spring with the firm Oshkosh Defense, a subsidiary of Oshkosh Corporation.
