One approach to try “to understand 3D vision in the praying mantis, the only invertebrate known to have this ability, and compare it with vision in humans” is to equip a mantis with specially-built tiny 3-D glasses, suspend the spectacles-clad mantis upside down from a post, and then monitor that mantis’s response to artificially created images that mimic the motion of other insects. Jenny Reed, Vivek Nityananda, and several of their colleagues at Newcastle University took exactly this approach. They blog about it. This video shows some of what they have done and found:
On April 17th, Roy Glauber, who was awarded one half of the 2005 Nobel Prize in Physics “for his contribution to the quantum theory of optical coherence”, visited USTC and gave a lecture “Two Hundred Years of Light Waves, One Hundred Years of Light Quanta” for the students on the next day. During his visit, professor Glauber accepted a face-to face micro-interview.
A kind of chicken soup for the soul story about Roy Glauber is very popular in China which was published in Reader in 2009. For many years before winning his Nobel Prize, Glauber were familiar to the audiences of Ig Noble Prize, where he took a bow each year as “Keeper of the Broom”. In the chicken soup story, his sweeping the stage was described as a kind of cleaning the dust of mind. When hearing that in the interview, professor laughed and shared the context of the story.…
The pitch has dropped – again. This time, the glimpse of a falling blob of tar, also called pitch, represents the first result for the world’s longest-running experiment…. Up-and-running since 1930, the experiment is based at the University of Queensland in Australia and seeks to capture blobs of pitch as they drip down, agonisingly slowly, from their parent bulk.
The Queensland experiment already features in the Guinness World Records and won an IgNobel prize in 2005. It was set up by physicist Thomas Parnell to illustrate that although pitch appears solid, shattering when hit with a hammer at room temperature, it is actually a very viscous liquid.
The eventual result follows several near misses, according to the University of Queensland. John Mainstone, who oversaw the experiment for more than 50 years until his death last August, missed observing the drops fall three times – by a day in 1977, by just five minutes in 1988 and, perhaps most annoying, in 2000, when the webcam that was recording it was hit by a 20-minute power outage….
