Physics Week in Review: June 13, 2015

The physics of butterfly flight, the universe as a fruitcake, and all the things we still don't understand about water are among this week's physics highlights.

To Predict Turbulence, Just Count the Puffs. These tiny swirls of fluid live, die, reproduce, and spark turbulence. "Turbulence emerges when the birth rate of puffs exceeds the death rate, and the puffs are able to colonize the fluid."

The Physics of Butterfly Flight. "First off, butterflies are totally the dancing queens of the animal world!  They have amazing and unnecessarily huge wings for their tiny bodies.  Their wings are way bigger than many other insects of the same weight. And new research shows butterflies don’t even need all of that wingspan - their wings are so massive they can fly even with half their wing cut off."

This week in Internet Drama: When Smart People Say Stupid Things. Biologist Tim Hunt, who won the 2001 Nobel Prize in medicine, was giving a talk at the World Conference of Science Journalists in South Korea when he expressed his support for sex-segregated labs and admitted he has a reputation as a chauvinist. His problem with female scientists: “You fall in love with them, they fall in love with you, and when you criticize them, they cry!” Per The Daily Beast: "Maybe lady scientists just can’t take a joke? Not so, tweeted prominent science writer Deborah Blum, who wrote that Hunt doubled down when she asked him about his comments. 'I was hoping he'd say it had been a joke. But he just elaborated. Sigh.' Blum tweeted. 'He did tell me that he thought I might hold up okay because I didn't seem the crying kind.'"

Naturally, this sparked an online outcry. The Guardian alone featuredseveral different commentaries and highlighted the unseen women scientists behind Hunt’s Nobel prize, while Dean Burnett went for humor, suggesting old white men should be banned from science. Maybe he's onto something, given a handful of studies (highlighted ironically by the folks at Improbable Research) on how “Interacting with Women Can Impair Men’s Cognitive Functioning.” The best thing that came out of the fracas: Female Scientists Mocked Nobel Laureate’s Remarks With a #DistractinglySexy Campaign on Twitter.

Hunt soon issued a typical non-apology, saying he was “really sorry,” and -- contrary to what he told Blum -- tried to play the ladeez-just-can't-take-a-joke card, insisting it was "intended is a light-hearted ironic comment" that was "interpreted deadly seriously by my audience." Okay, except he “did mean” his sexist remarks -- hey, he was just "trying to be honest." Mostly, he was sorry he said those things to a roomful of science journalists, many of whom were women. That apology played about as well as his original ill-advised remarks.

The Royal Society promptly distanced itself from Hunt's comments, and by Friday he had resigned his honorary position at University College London. The American Association for the Advancement of Science pulled Hunt from a planned webinar in which he was scheduled to offer advice on "persevering in science." The President of the European Research Council, in contrast, defended Hunt, saying "during the time I have worked with him on the ERC Scientific Council he has only ever been a supporter of gender balance." Sadly, Hunt is not alone in his bigotries. Slate highlighted a few of the most boneheaded, racist, and sexist comments from Nobel laureates. Even then, such blatant instances of bias are only the most publicized examples of a more pervasive problem.

How Misperceptions About Math Contribute to the Gender Gap, according to a new study in Frontiers of Psychology. "Lead author Samantha Nix, a PhD student at Florida State University and lead author of the paper, said she had been interested in the way people talk about math and science. 'A very common thing that people say and that has been part of the scholarly literature is this whole concept of ‘I’m just not a math person,’” she said. “And that really may be blocking people from making the decision to enter these fields.'"
