Steven Weinberg doesn’t like Quantum Mechanics. So what?
(200 words excerpt, click title or image to see full post)

A few days ago, Nobel laureate Steven Weinberg gave a one-hour lecture titled “What’s the matter with quantum mechanics?” at a workshop for science writers organized by the Council for the Advancement of Science Writing (CASW).In his lecture, Weinberg expressed a newfound sympathy for the critics of quantum mechanics. “I’m not as happy about quantum mechanics as I used to be, and not as dismissive of the critics. And it’s a bad sign in particular that those physicists who are happy about quantum mechanics, who see nothing wrong with it, don’t agree with each other about what it means.” You can watch the full lecture here. (The above quote is at 17:40.)It’s become a cliché that physicists in their late years develop an obsession with quantum mechanics. On this account, you can file Weinberg together with Mermin and Penrose and Smolin. I’m not sure why that is. Maybe it’s something which has bothered them all along, they just never saw it as important enough. Maybe it’s because they start paying more attention to their intuition, and quantum mechanics – widely regarded as non-intuitive – begins itching. Or maybe it’s because they conclude it’s the likely reason we haven’t seen any ...
