David Mermin says QBism puts the scientist back into science

A new understanding of quantum mechanics restores the balance between scientists and the objects they study, says David Mermin, the Horace White professor of physics emeritus, in this article in Nature.

“They call their new point of view ‘QBism’: Q is for quantum and B is for Bayesian — a view of probability that includes an agent who makes bets and updates odds. QBism attributes the muddle at the foundations of quantum mechanics to our unacknowledged removal of the scientist from the science,” Mermin says.

Jane Wang derives physical law controlling the path of hungry Tiger Beetles

Prof Jane Wang has developed an explination for the path Tiger Beetles take as they chase their prey. What looks like a messy looping path can be defined by physical rules that affect the beetles motion.

Sol Gruner's high-pressure cryocooler goes from the lab to world marketplace

A high-pressure cryocooler developed by Sol Gruner's lab is now available for sale through the Ithaca based company ADC Inc. The device is used to study proteins and simplifies the preparation of protein samples to be used in X-ray crystallography. Under licence with Cornell ADC is producing the cyrocoolers and has completed its first order with a research center in Japan.

David Awschalom to give Cornell's 2014 Hans Bethe Lecture Series

David Awschalom will present three lectures on spintronics as the 2014 Hans Bethe lecturer. In 1982 Awschalom received his Ph.D from Cornell in experimental physics and he is currently the Liew Family Professor in Molecular Engineering at the University of Chicago. As one of the world leaders in spintronics, Awschalom will be presenting research and engineering applications of this emerging field at a series of talks the week of April 7. More on Awschalom's background can be found in the Chronicle.

UPDATE (4/14/2014): Wondering what spintronics are? Check out this article by George Lowery in the Chronicle.

Schedule for Hans Bethe Lecture series:

Monday, April 7 – Department of Physics Colloquium
4:00pm – Schwartz Auditorium, Rockefeller Hall
“Beyond Electronics: Abandoning Perfection for Quantum Technologies”

Tuesday, April 8 – LASSP Seminar
4:00pm – 700 Clark Hall
“Ultrafast Quantum Control of Single Electron Orbital and Spin Dynamics in Diamond”

Wednesday, April 9 – Public Lecture

Itai Cohen and Jane Wang's work on fruit fly flight featured in New York Times

Itai Cohen & Jane Wang investigate how flies recover to flight disturbances, concluding that a small group of fly neurons is actually “solving calculus problems.” Click here for the full New York Times article and related video.
