Another great achievement of Dr. Feynman's was the creation of a mathematical theory that accounts for the phenomenon of super fluidity in liquid helium. Along with Murray Gell-Mann, Feynman did fundamental work with weak interactions like beta decay. Years later, Dr. Feynman was an important part of the development of quark theory by putting forward his parton model of high-energy proton collision processes. Furthermore, Dr. Feynman introduced new computational techniques and notations into physics, most importantly, the Feynman diagrams that perhaps more than any formality in recent scientific history, have altered how basic processes of physics are calculated and conceptualized.
Feynman was considered a superb teacher, and received many awards and honors, the one he admired most being the Oersted Medal for Teaching, which was awarded to him in 1972. Critics and fellow scientists around the world held many of his publications in high esteem, and his some of his works were written for the general public, so that all people might have an opportunity to grasp the basic concepts of physics. His more advanced writings have become important assets to researchers and students; some of his works have even made their way into textbooks.
Another of his most famous contributions is his work in the Challenger investigation when it crashed in 1986. His notorious demonstration of the O-rings to cold was during this research, an experiment that
