Medical devices are simply an advanced understanding that began with understanding electromagnetic waves through Maxwell’s equations. Each of the following 4 equations has a different name, by which we call’em, but together…

Two new Baryons at LHC.
Two new Baryons at LHC. Two new Baryons at LHCb. LHCb, the famed experiment at CERN, Switzerland found a year ago two new Baryons. These are important steps in testing the validity of our state of the art understanding of current model of the Physical Universe, mostly in considering the “particle constituents” of the matter…
