Today is Independence Day for the United States of America. But more importantly, today was the day that the Large Hadron Collider announced the discovery(ish, because more experiments have to be done to verify its other properties) of the Higgs boson!
This is HUGE! It's an amazing vindication of the Standard Model of particle physics as it stands today, and it should be the last nail in the coffin of the old trope I have heard frequently that there is no new interesting research to be done in physics. So with that in mind, happy Independence Day, but more importantly, HAPPY HIGGS DAY!!!
