Mysteries of the Universe After Einstein

Mysteries of the Universe After Einstein This is just a short summary of what we know we need to learn about the universe, with some speculations why we need to proceed with learning about them.  There are many YouTube lectures … Continue reading

Symmetries in the Mathematical Description of Nature

Part of the consideration of the question of the connection of mathematics to the understanding of nature is the discovery of symmetries in nature, and the formulation of this symmetry in mathematics.  Symmetry was established in this connection when Emily … Continue reading

The Effectiveness of Mathematics in Describing the Universe

NOVA just had a show on this question.  But besides the original question is that of what type of answer are you looking for, or what answer will you accept?  Otherwise the question is largely undefined. There are several simple … Continue reading

LUX Rules Out Previous Dark Matter Results

The LUX dark matter search experiment announced its first results this morning, almost totally ruling out previous experiments that had evidence for dark matter particles at low mass. LUX had expected 1550 dark matter events if the other detections were … Continue reading

Where Our Mass Comes From

Having begun the Age of the Higgs last year, which gives mass to all quarks and force particles except photons, we might expect that that is where most of our mass comes from. This is not the case, and we … Continue reading

More About Supersymmetry

  First of all, is a photo of Peter Higgs as a young man in 1954, about the time that he developed the Higgs theory. Next, in the discussion of SUSY, I didn’t include a diagram showing the SUSY particles … Continue reading

Introduction to the Large Hadron Collider at CERN

The Large Hadron Collider (LHC) at the CERN laboratory in Geneva is well described in detail on their website cern.ch as well as in YouTube videos.  I am just giving a brief introduction here for an OLLI class. The LHC collides … Continue reading

Introduction to the ATLAS Detector at the LHC

The ATLAS detector site www.atlas.ch provides a comprehensive presentation of the detector and its physics.  This is just a brief presentation for my OLLI classes. I don’t mean to slight the other general detector at CERN which is CMS, but I … Continue reading

What Might the Higgs Boson Imply? (Supersymmetry)

The Higgs Boson discovery must still meet several tests to verify that it is the standard model Higgs.  It’s coupling in various production channels of particles must show that its couplings are exactly proportional to the masses of the particles … Continue reading
