Let's be honest: size matters! Tonight, though, you will find out that bigger is not better! Joins us for a trip into the world of micro-science and get the chance of winning Pint of Science goodies!
There’s Plenty of Room at the Bottom!
Giorgio Volpe (Lecturer)
In 1959, the famous American physicist Richard Feynman suggested that there was plenty of room at the bottom (i.e. at atomic scale) for novel science. Feynman’s vision is now becoming a reality thanks in part to micromotors and nanomotors – tiny biological or manmade devices that can convert energy from their environment into autonomous motion. From personalized healthcare to environmental sustainability and security, can these tiny devices help us address some of the key challenges facing today’s society?
Optical Tweezers: Tractor Beams for Nanoparticles
Chris Dawson (Optical Engineer)
Optical tweezers use lasers to trap and manipulate the motion of microscopic objects, in a huge variety of scientific research. Under the right conditions, we can use these laser systems to levitate and cool nanoparticles to temperatures just above absolute zero. This gives us a way to see whether we get quantum "weirdness" and try to answer questions about where common-sense physics ends and quantum mechanics begins. I’ll talk a little bit about a planned space mission to carry out this test and about how we should be able to use these devices to see through walls and navigate underwater.
