There is nothing so compelling as a story about falling down,
recovering your footing, and then charging over the goal line completely
redeemed … unless it is two such stories. The Denver Broncos’ Super Bowl 50
victory and the laser interferometer gravitational-wave observatory’s (LIGO’s)
detection of gravity waves offer parallel examples. What, football and physics?
Yep. I watched the big game on TV, like tens of millions of others. But as a
technical consultant to LIGO, I had a Goodyear blimp’s view of their gridiron
when the collaboration fumbled its funding, recovered its mojo, and then sprinted to
victory by observing gravitational radiation generated more than a billion
One of the things I like the most when I do data analysis is to use "pure thought" to predict in advance the features of a probability density function of some observable quantity from the physical process I am studying. By doing that, one can try one's hand at demonstrating one's understanding of the details of the physics at play.
In this research we derived absolute neutrino masses by geometric interpretation of the Standard Model hierarchies. Numerous confirmations may indicate that, besides the problem of Higgs sector many external parameters, the SM is a complete low energy particle interaction theory not crying for new physics. But there are serious problems with understanding flavor in SM phenomenology. Firstly, equal number ‘3’ of SM particle generations coincide with the dimension number of outer euclidean 3-space and secondly, the factual SM particle mass and mixing hierarchies at leading approximation appear solutions of the ‘Metric’ equation for unit vector direction angles in euclidean 3-space geometry.
I (T.D.) am very happy to host here today a guest post by Daniel Hoak, a member of the LIGO collaboration, who participated in the discovery of gravitational waves that made headlines one week ago in the world media. Daniel earned his PhD in 2015 with the LIGO collaboration, and is currently working at the Virgo detector outside of Pisa. Daniel's picture is on the left.
Yesterday and today I have been spending time in Rome together with 600 Italian colleagues, at a symposium named "What Next". The idea is to discuss what should be the strategy of the institute to participate and support basic research in fundamental physics in the next few decades.
The format of the event is of short summary talks by ten "working groups" that examined different macro-areas: Precision SM Physics, Cosmic Ray Physics, Neutrino Physics, Flavour Physics, Gravitational Waves, Beyond the SM Physics, New Technologies, Fundamental Physics, and Dark Matter (I might have forgotten one). To each summary, delivered by two or three leaders of each working group, follows an open discussion that is allotted at least as much time as the presentations.
Information is not destroyed but it is even more scrambled up than anyone thought by black holes. I have used the framework of relativization, to compute the temperature of the proposed firewalls. It would be about 1.410 septillion Kelvin. Relativization which has been developed in open peer reviewed literature and conference presentation in to a comprehensive theory combining General Relativity with Quantum Field Theory. Black holes shred information, then burn it in a furnace hotter than millions of Suns.
Higgs sector is the least advanced one in the Standard Model. There are two ways of developments – theoretical and semi-empirical. The main content of the latter is looking for physically meaningful regularities of the empirical parameter system especially in the ratios and hierarchies of masses and mixing angles in flavor groups.
The first law of thermodynamics is commonly known as the law of conservation of energy. This means that
in any process, no matter how big, small, long or short, the amount of energy
of the system will always remain the same throughout time, it is a constant. So if you run an engine, build a bridge, turn
a turbine, boil a liquid or do anything else for that matter, the total energy
before and after this (and all processes) will be the same. You can only convert energy from
Technological advances may be ushering in a new era of understanding in the search for fundamental physical particles - including dark matter - said Professor Alex Murphy of the University of Edinburgh's School of Physics and Astronomy at the AAAS meeting in Washington, D.C.
Deep space observations together with experiments far underground are hunting for dark matter - an elusive material which, together with dark energy, is thought to account for about 94 percent of the universe. You can read all about dark matter and dark energy here.
Comment on the Number of Flavors in Standard Model
A widely used definition (see e.g. Wikipedia for a summery) of the number of particle ‘flavors’ in the SM is 6: 3 particle mass copies (e. g. electron, muon, tau for charged leptons; u, c, t for up-quarks …) doubled by the two up- and down- states.
Flavor is still a mystery in the SM. Historical Rabi’s quip “Who ordered the muon?” is steel urgent now for the three flavor mass copies of elementary particles.
