Northrop successfully launches Cygnus cargo spacecraft for the ISS

Posted by in categories: materials, space

An Antares rocket from Northrop Grumman has successfully launched the Cygnus cargo spacecraft on its way to the International Space Station. The launch happened at 9:59AM from the Mid Atlantic Regional Spaceport as anticipated. Assuming nothing unusual happens, NASA says the cargo vessel will arrive at the ISS on Monday, November 4, carrying a huge load of supplies and scientific materials.

Researchers uncover an anomaly in the electromagnetic duality of Maxwell Theory

Posted by in categories: information science, particle physics, quantum physics, space

Researchers at the Kavli Institute for the Physics and Mathematics of the Universe (WPI) and Tohoku University in Japan have recently identified an anomaly in the electromagnetic duality of Maxwell Theory. This anomaly, outlined in a paper published in Physical Review Letters, could play an important role in the consistency of string theory.

The recent study is a collaboration between Yuji Tachikawa and Kazuya Yonekura, two string theorists, and Chang-Tse Hsieh, a condensed matter theorist. Although the study started off as an investigation into string theory, it also has implications for other areas of physics.

In current physics theory, classical electromagnetism is described by Maxwell’s equations, which were first introduced by physicist James Clerk Maxwell around 1865. Objects governed by these equations include electric and magnetic fields, electrically charged particles (e.g., electrons and protons), and magnetic monopoles (i.e. hypothetical particles carrying single magnetic poles).

New Neural Network Could Solve The Three-Body Problem 100 Million Times Faster

Posted by in categories: mathematics, physics, robotics/AI, space

The three-body problem, one of the most notoriously complex calculations in physics, may have met its match in artificial intelligence: a new neural network promises to find solutions up to 100 million times faster than existing techniques.

First formulated by Sir Isaac Newton, the three-body problem involves calculating the movement of three gravitationally interacting bodies – such as the Earth, the Moon, and the Sun, for example – given their initial positions and velocities.

It might sound simple at first, but the ensuing chaotic movement has stumped mathematicians and physicists for hundreds of years, to the extent that all but the most dedicated humans have tried to avoid thinking about it as much as possible.
