zapatos Posted May 15, 2017 Share Posted May 15, 2017 Today I learned that Marie Skłodowska Curie was a smart lady. She was the first woman to win a Nobel Prize, the first person and only woman to win twice, the only person to win a Nobel Prize in two different sciences, and was part of the Curie family legacy of five Nobel Prizes. Nobel Prize in Physics (1903, with Pierre) Nobel Prize in Chemistry (1911) Curie died in 1934, aged 66, at a sanatorium in Sancellemoz (Haute-Savoie), France, due to aplastic anemia brought on by exposure to radiation while carrying test tubes of radium in her pockets during research, and in the course of her work at field hospitals during World War I. Coincidentally I read an article about Marie Cure this weekend. In addition to what you've already pointed out, I learned that her original notebooks are kept in a lead lined box due to radioactivity. Anyone examining them must wear appropriate safety gear. 1 Link to comment Share on other sites More sharing options...

Mordred Posted May 24, 2017 Share Posted May 24, 2017 (edited) Today I learned 3 and 5 year olds have far too much energy. If I could harness it in a humane fashion I would solve the energy crisis.

DrP Posted May 31, 2017 Share Posted May 31, 2017 That may be true in some cases, but it does sound like huge generalisation to me. I learnt that there is a Blackbird nesting in one of our storage buildings that doesn't seem too frightened of me as I walk through it. Link to comment Share on other sites More sharing options...

DrKrettin Posted May 31, 2017 Share Posted May 31, 2017 Today I learned about Broody Hens and how they don't like to be disturbed while they are setting. “Puck-AAARRRGGGH!” If you have the good luck to have a hen go broody, try getting her to hatch out some duck eggs, as I did once. Poor thing thinks she's got half a dozen chicks when they hatch, and proudly marches them off on foraging expeditions. That works until she walks past the pond, and she goes totally berserk when the "chicks" all go for a swim. It's the funniest ever farmyard scene. 1 Link to comment Share on other sites More sharing options...

We have ducks and chickens but all females. We are trying to get the broody hen off the nest; she lays there whether there are eggs under her or not. I'd love to get a fertilized duck egg under her.

Roger Dynamic Motion Posted May 31, 2017 Share Posted May 31, 2017 (edited) Twisting fibers together to form threads not only makes the thread stronger in thickness, it transfers stress more efficiently since the sides of the thread compresses when the ends are pulled. The average bed sheet has about a million twists of fiber.

Phi for All Posted May 31, 2017 Share Posted May 31, 2017 Because the time and distance from the center of the wheel to the ream 360 Deg. must be the same . Since this has nothing to do with fiber twisting, I'll assume it's a weird and very poor response to the title of the late Steven Vogel's book, Why the Wheel is Round. I highly suggest you read it and add to your knowledge. Link to comment Share on other sites More sharing options...

michel123456 Posted June 6, 2017 Share Posted June 6, 2017 (edited) Not today, but recently I learned why some mummies look like screaming. After some post on FB from a friend of mine about the Phaleron mass grave. An archaelogist wrote: I just wanted to make a small comment, with regards to the jaws and postmortem opening, from a biological perspective. Since mandibles are attached to the skulls by joints and two muscle types (masseter and pterygoid), after death, these parts are lost, so mandible drops and gives that "terrified" look.
