Before you turn it all over to AI: Why the Laws of Robotics fail

Jonathan Bartlett, Eric Holloway, and Brendan Dixon explain: Prolific science and science fiction writer Isaac Asimov (1920–1992) developed the Three Laws of Robotics, in the hope of guarding against potentially dangerous artificial intelligence. They first appeared in his 1942 short story Runaround: A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey orders given it by human beings except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. Asimov fans tell us that the laws were implicit in his earlier stories. A 0th law was added Read More ›

Eugenics and the “bad guy” in everyone but Darwin

This article about Francis Galton, Charles Darwin’s cousin, a key figure in the eugenics movement, manages to avoid mentioning Darwin, even though he was clearly among those Victorians for whom racism was a normal point of view. Read More ›

Projectiles found at 20 kya earlier than thought. An advantage for modern humans vs Neanderthals?

The thesis that modern humans had a competitive advantage in projectiles might be a bit hasty. One is reminded of the claim that modern humans could do art and Neanderthals couldn’t, and then we found Neanderthal art. Read More ›

Language is much more complex than once thought

Researcher: Our brains process language with astonishing speed and 'immediacy', in a dynamic network of interacting brain areas. All the relevant information becomes available immediately, as we start combining the meanings of individual words, unifying the different sources of information. To speed up this process, our brain actively predicts what is coming next (for instance, we might expect 'newspaper' to follow 'the editor of the ...'). Read More ›

Researchers: The Golden Ratio is found in human skulls but not other animal skulls

Researchers: "The other mammals we surveyed actually have unique ratios that approach the Golden Ratio with increased species sophistication," says Rafael Tamargo, M.D., professor of neurosurgery at the Johns Hopkins University School of Medicine. "We believe that this finding may have important anthropological and evolutionary implications." Read More ›

Are the “redundant” particles of the universe evidence of fine-tuning?

Rob Sheldon: Despite McMaster U. thinking this odd, and believing (hoping?) for a failure of the Standard Model, I see this as a necessary means of storing the information in the hot Big Bang, and demonstrating the ultimate fine-tuning of the cosmos. Read More ›

Cells’ feedback circuitry is all in the math

At Quanta: “What math and engineering and biology have in common, at least modern engineering, is enormous hidden complexity,” Doyle said. Take, for example, a cellphone. It seems simple to operate, but underneath, many layers of control circuits are built atop one another. Read More ›

Does the electron “know” of an impending collision?

Researcher: The electron not only receives the expected momentum, but additionally one third of the photon momentum that actually should have gone to the atom nucleus. The sail, (electron), of the boat, (nucleus), therefore "knows" of the impending accident, (collision from the photon), before the cords tear and steals a bit of the boat's (nucleus's) momentum.
