Physicists make breakthrough in understanding turbulent fluids
There have been accusations for years that the Major League ball is “juiced,” thus accounting for the increasing power numbers.
MLB officials have categorically denied that, and last year, commissioned a study of the baseball and how it’s produced.
In the landmark 85-page independent report replete with color graphs, algorithms and hypotheses, a group of 10 highly-rated professors and scientists chaired by Alan Nathan determined that the ball is not livelier or “juiced.” Nathan is a professor emeritus of physics from the University of Illinois at Urbana Champaign.
The surge in home runs “seems, instead, to have arisen from a decrease in the ball’s drag properties, which cause it to carry further than previously, given the same set of initial conditions – exit velocity, launch and spray angle, and spin. So, there is indirect evidence that the ball has changed, but we don’t yet know how,” wrote Leonard Mlodinow, in the report’s eight-page executive summary.
Growing up in Trinidad and Tobago, Kandice Tanner went to a school where she was one of only a dozen girls among 1200 pupils. She had switched from an all-girl school to avoid the distractions of socializing and to take the more advanced math classes offered at the boys’ school. “Being submerged in an all-male environment early on was beneficial to me,” Tanner says. “I felt comfortable with guys, and more important, I knew I could hold my own in a male-dominated environment.”
Illinois Physics Professor Philip Phillips and Math Professor Gabriele La Nave have theorized a new kind of electromagnetism far beyond anything conceivable in classical electromagnetism today, a conjecture that would upend our current understanding of the physical world, from the propagation of light to the quantization of charge. Their revolutionary new theory, which Phillips has dubbed “fractional electromagnetism,” would also solve an intriguing problem that has baffled physicists for decades, elucidating emergent behavior in the “strange metal” of the cuprate superconductors.
The BPS Art of Science Image Contest took place again this year, during the 63rd Annual Meeting in Baltimore. The image that won first place was submitted by Angela Barragan, PhD Candidate at the Beckman Institute UIUC. Barragan took some time to provide information about the image and the science it represents.
