A Long-Sought Proof, Found and Almost Lost

Thomas Royen who solved the Gaussian correlation inequality (CGI)

Thomas Royen at his home in Schwalbach am Taunus, Germany.

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.

NASA Discusses Discovery of Earth-Size, Habitable-Zone Planets

Original air date: Feb. 22, 2017 10 a.m. PT (1 p.m. ET, 1800 UTC) NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water. The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water — key to life as we know it — under the right atmospheric conditions, but the chances are highest with the three in the habitable zone. The briefing participants were: Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA Headquarters in Washington Michael Gillon, astronomer at the University of Liege in Belgium Sean Carey, manager of NASA’s Spitzer Science Center at Caltech/IPAC, Pasadena, California Nikole Lewis, astronomer at the Space Telescope Science Institute in Baltimore Sara Seager, professor of planetary science and physics at Massachusetts Institute of Technology, Cambridge For more information on exoplanets, visit: http://exoplanets.nasa.gov

Why Doesn’t Antimatter Anti-Gravitate?

antimatter anti-gravity?

If there were some type of matter that had negative gravitational charge, it would be repelled by the matter and energy that we are aware of.

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.

Series of New Posts: Lectures, talks, podcasts, etc…

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.

Why a NASA spacecraft could bounce, crunch or sink on icy Europa

Why a NASA spacecraft could bounce, crunch or sink on icy Europa

Sometime in the early 2030s, NASA hopes to attempt a landing on Jupiter’s moon Europa. A four-legged spacecraft would descend towards the icy surface, ready to hunt for signs of alien life in a buried ocean.

Landing on Jupiter’s moon in search of alien life won’t be easy.

Transparent silver: Tarnish-proof films for flexible displays, touch screens

University of Michigan researchers have created a transparent silver film that could be used in touchscreens, flexible displays and other advanced applications. L. Jay Guo, professor of electrical engineering and computer science, holds up a piece of the material. Credit: Joseph Xu/Michigan Engineering.

The thinnest, smoothest layer of silver that can survive air exposure has been laid down at the University of Michigan, and it could change the way touchscreens and flat or flexible displays are made.

LHCb observes an exceptionally large group of particles

The LHCb experiment at CERN is a hotbed of new and outstanding physics results. In just the last few months, the collaboration has announced the measurement of a very rare particle decay and evidence of a new manifestation of matter-antimatter asymmetry, to name just two examples.

The image above shows the data (black dots) of the reconstructed mass distribution resulting from the combination of the Ξc+ and K- particles. The five particle states are the five narrow peaks standing out from the distribution of data. (Image: LHCb collaboration)

NewSpace NYC and NY Society of Security Analysts – A New Space Age Race: Interplanetary Investments

Three observations from tonight:
1) EVERYONE wants to be a leader but most are not visionaries.
2) A few are visionaries but lack the leadership, business skills and/or chutzpah to make it happen.
3) Then there are the very few with both vision and chutzpah to make it happen. But, they are not just the Musks or Bezoses, they are the smaller pioneers, some of whom I met tonight, and they are the key for getting to and crossing the tipping point to a vibrant commercial space industry/economy.
