Mark Alford

Mark Alford, PhD, professor of physics in Arts & Sciences at Washington University in St. Louis, participated Jan. 29 in a roundtable discussion in New York about the quantum mind theory of consciousness. Quantum mind is a fashionable theory originally proposed by physicist Roger Penrose that grounds perception in the periodic collapse of quantum entangled electrons in our brain. Alford, who studies phenomenon that can only be explained by quantum mechanics nonetheless played the role of the skeptic in the discussion, which was videotaped and posted on the web.

Washington University Frontiers in Technology and Science, a one-day conference modeled on the Kavli Frontiers of Science conference, hopes to connect WUSTL faculty in the sciences, engineering or mathematics and spur cross-disciplinary collaborations. The conference will be held from 10:30 a.m.-4:30 p.m. Saturday, Sept. 25, in Cupples I, Room 199.

New calculations by an international group of theorists paint a better picture of the nature of quark stars and suggest a way for astronomers to find the quark stars among the neutron stars. But WUSTL physicist Mark Alford, commenting on the journal publication in a news article posted Jan. 15 at PhysicsWorld.com, suggests that the new work may not be the last word. Alford, who uses mathematical modeling to explore the properties of quark stars, contends that the mathematical theory it uses is only truly accurate when the quarks are millions of times denser than they are in real neutron stars.
