2Physics Quote:
"Today’s most precise time measurements are performed with optical atomic clocks, which achieve a precision of about 10-18, corresponding to 1 second uncertainty in more than 15 billion years, a time span which is longer than the age of the universe... Despite such stunning precision, these clocks could be outperformed by a different type of clock, the so called “nuclear clock”... The expected factor of improvement in precision of such a new type of clock has been estimated to be up to 100, in this way pushing the ability of time measurement to the next level."

Upcoming Physics Conferences

From today we start this feature on suggestion from some of our physicist friends. If anyone wishes to freely advertize Physics jobs or conferences in 2Physics, he/she is welcome to put an entry and a web-link following our 'comment' link that can be found at the bottom of any of our postings. From time to time we'll publish the list. Our today's list is for conferences only.

July 18-21: "Quantum reality, relativistic causality, and closing the epistemic circle: an international conference in honour of Abner Shimony" (Waterloo, Ontario, Canada)
July 20-21: "Teaching General Relativity" (Syracuse)
July 23-29: "Eleventh Marcel Grossmann Meeting on General Relativity" (Berlin)
Jul 31-Aug 4: "Cosmic Frontiers" (Durham, UK)
August 1-4: "1st international workshop on transmission of information and energy in nonlinear & complex systems " (Singapore)
August 6-11: "Intl congress on mathematical physics" (Rio de Janeiro, Brazil)
August 7-15: "Key Approaches to Dark Energy" (Barcelona, Spain)
August 24-26: "Quantum Gravity in Americas" (Pennstate)
August 25-29: "3rd Feynman festival" (College Park, Maryland, USA)
September 3-12: "International advanced summer school on modern mathematical physics: theoretical cosmology and observational status of modern cosmology" (Dubna, Russia)
September 7-9: "Maxwell 150 Years On" (Aberdeen, UK)
