O.o.

This paper describes a new and efficient method of defining an annular region of a curl-free magnetic field with specific physics and coil properties that can be used in stellarator design. Three statements define the importance:

Codes can follow an optimized curl-free initial state to a final full-pressure equilibrium. The large size of the optimization space of stellarators.

Approximately fifty externally-produced distributions of magnetic field, makes success in finding a global optimum largely determined by the starting point.

Complex cognitive dissonance disorder guaranteed. 😬.

Garrett Lisi, the so called “Surf Bum with a Theory of Everything (or T.O.E.)”, is a PhD theoretical physicist who has refused to be captured by the theoretical physics community. By making shrewd investments, he has avoided holding meaningful employment for his entire adult life. Instead, he lives in Maui and travels the world chasing the perfect wave.

If you are interested in mind uploading, then I have a research paper for you to consider. One of the serious issues with mind uploading is the computer substrate. Simulating the brain will require a new and incredible computing capability. New techniques and new hardware are going to be required to make it practical. Of course, there is currently zero demand for mind uploading hardware, so the market is not going to provide this capability. However, there is incredible market demand for cutting edge hardware for machine learning and artificial intelligence. And it turns out that one potential technique for artificial intelligence simulates the way that the brain works: neuromorphic computing. And there is a relatively new type of electronic component that seems to mimic some of the functions of a brain’s neuron: the memristor. Memristors are relatively new, having only been fabricated for the first time by HP in 2008. So I am trying to keep up with the latest developments in memristive technology.

Here are some excerpts from the paper:

“…Artificial Neural Network (ANN) algorithms offer fast computations by mimicking the neuronal network of brains. A weight matrix is used in neural networks (NNs) for parallel processing that makes computing faster…The memristor has attracted much attention because of its potential to have linear multilevel conductance states for vector-matrix multiplication (output = weight × input), corresponding to parallel processing…”

Edward Alexander Bouchet (September 15, 1852 – October 28, 1918) was an African American physicist and educator and was the first African-American to earn a Ph.D. from any American university, completing his dissertation in physics at Yale in 1876. While completing his studies, Bouchet was also the first African American to be inducted in to Phi Beta Kappa for his stellar academic performance in his undergraduate studies. Bouchet’s original research focused on geometrical optics, and he wrote a dissertation entitled “On Measuring Refractive Indices.”

Unfortunately, after completing his dissertation, Bouchet was unable to find a university teaching position after college, probably because of racial discrimination. Bouchet moved to Philadelphia in 1876 and took a position at the Philadelphia’s Institute for Colored Youth (now Cheyney University of Pennsylvania), where he taught physics and chemistry for the next 26 years. Bouchet spent the next several years in several different teaching positions around the country. In 1916, Bouchet returned home to New Haven in poor health, and died in 1918 at age 66.

Dr. Bouchet’s impact on physics still resonates today around the world. The American Physical Society (APS Physics) confers the Edward A. Bouchet Award on some of the nation’s outstanding physicists for their contribution to physics. The Edward Bouchet Abdus Salam Institute was founded in 1988 by the late Nobel Laureate, Professor Abdus Salam under the direction of the founding Chairman Charles S. Brown. In 2005, Yale and Howard University founded the Edward A. Bouchet Graduate Honor Society in his name.

How interesting. Very adorable.

A heartwarming rescue of a baby elephant with the help of physics is winning the Internet. A tweet by IFS officer Ramesh Pandey gives a glimpse of the rescue efforts made by people and officials in Gumla, Jharkhand.

According to the tweet, the forest department along with people from the nearby village rescued the elephant using the Archimedes principle. Officials and locals filled the well with water to help the elephant out. The elephant was rescued without any injury.

A mysterious cosmic event might have ever-so-slightly stretched and squeezed our planet last week.

A theoretical physicist in England has won a prestigious award for her work on the theory of massive gravity, which could explain why gravity hasn’t constrained the rapid expansion of the universe. The $100,000 award honors the work of Claudia de Rham, who has worked for 10 years on a way to turn massive gravity theory into something measurable.

Cosmologists have puzzled for decades about how to marry gravity with the speed at which the universe is expanding. Gravity as we understand it would work to hold the universe together, not let it race apart from itself into eventual oblivion. Enter the counterpart to dark matter, dark energy, which is what scientists call whatever is pulling the universe apart.

She is now hopeful that advances in gravitational wave astronomy will make it possible to test the predictions of massive gravity theory within the decade.

“It would be amazing if it was shown to be right,” De Rham told The Guardian. “That may or may not happen, but what will happen is that we’ll have a much better fundamental understanding of gravity and that’s just something so deep, it’s one of the big questions today.”
