Richard P. Feynman an astounding theoretical physicist and professor
∆ Quantum mechanics & particle physics
∆ Quantum electrodynamics (QED) for which he shared a Nobel Prize
∆ Superfluidity of liquid helium
The diagram above is of a vector boson fusion producing a Higgs boson. Feynman developed this method of representing particle interactions which have been important to the understanding of work in particle accelerators such as the Large Hadron Collider.
The following is a wonderful video of Feynman talking about light
