Lore & Background
Richardson was born in Washington D.C. and attended high school at Washington-Lee in Arlington, Virginia, where he described the biology and physics courses as 'very old-fashioned' for the time. He took his first calculus course as a sophomore in college. He earned a B.S. They had two children, Jennifer and Pamela, and four grandchildren. He claimed he did not believe in an anthropomorphic God, though his specific beliefs were unclear. His past experimental work used Nuclear Magnetic Resonance to study quantum properties of liquids and solids at extremely low temperatures.
Reader's Guide
Robert Coleman Richardson's significance lies in his co-discovery of superfluidity in helium-3, a phenomenon where the liquid flows without viscosity at temperatures near absolute zero. His work advanced understanding of quantum behavior in macroscopic systems, with implications for theories of superconductivity and quantum fluids. Beyond his research, Richardson contributed to academic leadership at Cornell as vice provost for research and senior science adviser. His legacy includes mentoring graduate students, such as Osheroff, and fostering experimental techniques like Nuclear Magnetic Resonance at ultralow temperatures. The discovery of helium-3 superfluidity remains a cornerstone of modern cryogenics and condensed matter physics, influencing both fundamental science and technological applications in quantum computing and precision measurement.
Did You Know?
- Richardson shared the 1996 Nobel Prize in Physics with David Lee and then-graduate student Douglas Osheroff for the 1972 discovery of superfluidity in helium-3.
- He was an Eagle Scout and mentioned his Scouting activities in his Nobel biography.
Frequently Asked Questions
What discovery made Richardson famous?
In 1972 he identified superfluidity in helium-3, meaning the liquid could flow with zero viscosity at certain ultra-cold thresholds. This finding was made while he was working at Cornell University's Laboratory of Atomic and Solid State Physics.
Who shared the 1996 Nobel Prize in Physics with Richardson?
David Lee and Douglas Osheroff received the award alongside him, all three being credited for their collaborative work on helium-3 superfluidity.
Where did Richardson carry out his landmark experiments?
The critical helium-3 superfluidity work was performed at Cornell University's Laboratory of Atomic and Solid State Physics. His team pushed measurements into the sub-millikelvin regime to reveal the transition into the superfluid state.
Why is Richardson considered important in 20th-century physics?
His identification of superfluidity in helium-3 opened a new frontier in quantum many-body research and reshaped how physicists understood particle behavior near absolute zero. The 1996 Nobel Prize formally recognized the lasting impact of that 1972 breakthrough.
