"What's nice about our proposal is that we don't have to assume anything new," Kenneth Nollett of the Argonne National Laboratory in the US points out that, in alleviating the lithium problem, the Florida group's theory overestimates the amount of deuterium. It took a while for them to Nonetheless, we have a big problem: Physics explains the world around us with incredible precision and breadth. Apart from generalizing the notion of gauge Lie groups to Lie 2-groups and further, structural considerations in fundamental physics also led theoretical physicists to consider models for spacetime that are more general than than the notion of a .. And the modification needed to get this solution is rather tiny, just a small change in the real structure J of the spectral triple from ten years ago. The team «It usually makes pure mathematicians a bit uncomfortable if someone with an problem wants to hit it with fancy mathematical machinery, because the fit of theory to problem is rarely good, » says Doran. Reporting in the journal «Science», a group of mathematicians and physicists around Matthias Christandl, professor at the Institute for Theoretical Physics, provides an important contribution towards putting the «spooky action» to order. An interview with the Nobel Prize-winner David J. Now, particle physicists Pierre Sikivie and colleagues at the University of Florida in Gainesville think they have a straightforward solution. For a list of literature addressing this problem see Literature on quantization. Gross on the confusing state of theoretical physics. There were two groups: younger physicists, like Steve Weinberg and Lenny Susskind, who immediately believed it, and a group of older scientists, who didn't know very much quantum field theory, which is highly technical. Researchers are still grappling with the relativistic quantum theories that resulted.
