PPPL and Max Planck physicists reveal experimental verification of a key source of fast reconnection of magnetic fields
Magnetic reconnection, a universal process that triggers solar flares and northern lights and can disrupt cell phone service and fusion experiments, occurs much faster than theory says that it should. Now researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Germany’s Max Planck Institute of Plasma Physics have discovered a source of the speed-up in a common form of reconnection. Their findings could lead to more accurate predictions of damaging space weather and improved fusion experiments.

John Carlstrom gives the plenary lecture at the New Horizons in Inflationary Cosmology Templeton Conference organized by the Stanford Institute for Theoretical Physics.
Our understanding of the origin, evolution and make-up of the Universe has undergone dramatic and surprising advances over the last decades. Much of the progress has been driven by measurements of the fossil light from the big bang, called the cosmic microwave background radiation, which provides us with a glimpse of the Universe as it was 14 billion years ago. This talk will discuss what we know about the Big Bang and how we learned it. We will also talk about the new questions we are asking about the origin of the Universe and the experiments being pursued to answer them, peering back to the beginning of time.

The Institute for Research on Innovation & Science (IRIS) is the major national source for data to support fundamental research on the results of public and private investments in discovery, innovation, and education. It provides credible data and rigorous findings about the productivity and public value of the research enterprise to inform effective policy-making, support outreach, aid in research management, and expand the state of knowledge.

In order to fully understand the quantum world, we may have to develop a new realm of mathematics.
Mathematics might be more of an environmental science than we realize. Even though it is a search for eternal truths, many mathematical concepts trace their origins to everyday experience. Astrology and architecture inspired Egyptians and Babylonians to develop geometry. The study of mechanics during the scientific revolution of the 17th century brought us calculus.
Remarkably, ideas from quantum theory turn out to carry tremendous mathematical power as well, even though we have little daily experience dealing with elementary particles. The bizarre world of quantum theory — where things can seem to be in two places at the same time and are subject to the laws of probability — not only represents a more fundamental description of nature than what preceded it, it also provides a rich context for modern mathematics. Could the logical structure of quantum theory, once fully understood and absorbed, inspire a new realm of mathematics that might be called “quantum mathematics”?

When a German retiree proved a famous long-standing mathematical conjecture, the response was underwhelming.
As he was brushing his teeth on the morning of July 17, 2014, Thomas Royen, a little-known retired German statistician, suddenly lit upon the proof of a famous conjecture at the intersection of geometry, probability theory and statistics that had eluded top experts for decades.
Known as the Gaussian correlation inequality (GCI), the conjecture originated in the 1950s, was posed in its most elegant form in 1972 and has held mathematicians in its thrall ever since.

Every massive particle exerts a gravitational force. So what do antimatter particles do?
Why aren’t there any particles that fall upwards in the gravitational field of Earth? It would be so handy – If I had to move the couch, rather than waiting for the husband to flex his muscles, I’d tie an anti-gravitating weight to it and the couch would just float to the other side of the room.

I will be starting a regular series of posts of lectures, talks, podcasts, etc. If you have requests for topics, please feel free to comment on this post or send me a message via the contact links. The first of these posts is below:
On Oct. 7, 2015, Perimeter Institute Director Neil Turok opened the 2015/16 season of the PI Public Lecture Series with a talk about the remarkably simplicity that underlies nature. Turok discussed how this simplicity at the largest and tiniest scales of the universe is pointing toward new avenues of physics research and could lead to revolutionary advances in technology.
