This. This is the reason why I am passionate about chemistry.

Your Mass is NOT from Higgs Boson
The Higgs Boson is awesome but it’s NOT responsible for most of your mass!
The Higgs mechanism is meant to account for the mass of everything, right? Well no, only the fundamental particles, which means that electrons derive their mass entirely from the Higgs interaction but protons and neutrons, made of quarks, do not. In fact the quark masses are so small that they only make up about 1% of the mass of the proton (and a similar fraction of the neutron). The rest of the mass comes from the energy in the gluon field. Gluons are massless, but there is so much energy in the field that by E=mc^2 there is a significant amount of mass there. This is where most of your mass comes from and the mass of virtually everything around you.

During an unscheduled spacewalk on the space station’s exterior on Saturday morning, NASA astronauts Tom Marshburn and Chris Cassidy carried out the mother of all plumbing jobs: They detached a suspect ammonia pump, replaced it with a spare and watched for any further ammonia leakage.
“It will take some diagnostics, still, over the course of the next several days by the thermal systems specialists to fully determine that we have solved the problem of the ammonia leak,” said NASA commentator Rob Navias during the live NASA TV spacewalk broadcast. “But so far, so good.” Read more
“I don’t like honors. I’m appreciated for the work that I did, and for people who appreciate it, and I notice that other physicists use my work. I don’t need anything else. I don’t think there’s any sense to anything else. I don’t see that it makes any point that someone in the Swedish Academy decides that this work is noble enough to receive a prize. I’ve already got the prize. The prize is the pleasure of finding the thing out, the kick in the discovery, the observation that other people use it. Those are the real things. The honors are unreal to me. I don’t believe in honors. It bothers me, honors. Honors is epilets, honors is uniforms.”

The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them. This discovery suggests that rocky planet assembly is common in clusters, say researchers. Read more here.

Happy birthday, Mr. Feynman! Thank you for all the great explanations and inspiration.
