One hundred years of Fundamental Physics, starting with discoveries such as radioactivity and electron, have culminated in a theory which is called the Standard Model of High Energy Physics. This theory is now known to be the basis of almost all of known physics except gravity. We give an elementary account of this theory in the context of the recently announced discovery of the Higgs Boson. We conclude with brief remarks on possible future directions that this inward bound journey may take.
