The Zenithal Hourly Rate (ZHR) is the rate which would be seen by an experienced observer, in a VERY dark sky, and with the radiant in the zenith: actual observed rates very rarely reach the nominal ZHR for various reasons. The radiant is about halfway between the end star in the tail of the Great Bear (or the end of the handle of The Plough) and the head of Draco.
The School of Mathematics and Physics at Queen's University Belfast presents a lecture on the latest news from the largest science experiment ever built. The talk will be given by Dr. Tara Shears from the University of Liverpool, a renowned expert in particle physics and accomplished public speaker.
The Large Hadron Collider (LHC) is the most powerful particle collider ever built. It is capable of creating (fleetingly) the fundamental particles which form everything in the universe. In particle physics we've understood much about these tiny objects, and can describe their behaviour in an incredibly successful theory. However, there are many known unknowns: where and what is the mysterious Higgs particle? Why is there so little antimatter in the universe? What is dark matter? We have built the LHC to try to find answers, and in this talk, Dr. Shears will show you the latest findings.
The lecture will be at 6:30 pm on Thursday 12th January in the Larmor Lecture Theatre, Physics Building, QUB. Complimentary tea and coffee will be served in the Great Hall in the Lanyon Building (main entrance) from 6:00 pm - 6:20pm.
If you wish to attend this lecture, please reserve seats by either going to the website http://tinyurl.com/QUBPhysics or by calling 028 9097 3202.
This talk has been sponsored by the Science and Technology Facilities Council (STFC) and the School of Mathematics and Physics at Queen's University Belfast.
