(Phys.org) —Determining the mass of dark matter particles requires accounting for several factors, one of which is the velocity distribution of the particles. Most current estimates of dark matter mass involve assumptions ...
Everyone knows that 2 + 2 = 4, but why do we have arithmetic in the first place, and why is it true? Researchers at the University of Canterbury have recently answered these questions by "reverse engineering" arithmetic from ...

(PhysOrg.com) -- MIT researcher Scott Aaronson has certainly riled the physics community with his offer this past Friday, of $100,000 to anyone who can prove that scaled-up quantum computing is impossible. His original reason ...
(Phys.org) —Researchers have found that authors of "soft science" research papers tend to overstate results more often than researchers in other fields. In their paper published in Proceedings of the National Academy of ...
A major study of recent international data on school mathematics performance casts doubt on some common assumptions about gender and math achievement — in particular, the idea that girls and women have less ability due ...
