How do we see the unseeable? How are scientists shining a light on cancer? How can laser beams be used as tweezers and scissors?
Light is all around us and it is being used in incredible ways in medicine and biology. Light can be used to image microscopic objects such as cells, bacteria and small organisms. In healthcare, light can be used to treat a number of medical conditions, such as certain types of cancer. Light is also a useful research tool. Laser beams can be used to trap and move tiny objects and to punch holes in them.
International Day of Light, 16th May 2019
To celebrate the International Day of Light, Morgan and Sephie met undergraduate students from all disciplines in the Student Union building and showed them around a few experiments. The light connection caught them in the midst of hard revisions, and it was a pleasure to see the excitement in even the most arty or literary of them.
Students could see a mobile phone screen under the microscope, use their phone as a diffraction grating, and then experience life as seen through diffraction grating glasses. What a diffractive experience! They could also play with refraction and reflection in a water tank, and thus learn more about the principles of optical fibres.
Science Discovery Day, 9th March 2019
A record-breaking 1292 visitors took part in Science Discovery Day 2019 (Saturday 9 March) at the School of Physics and Astronomy welcome a record-breaking 1292 visitors through the doors.
People from across Tayside, Fife and beyond participated in a range of scientific hands-on activities, learning about everything from stars to starfish.
Our group’s activities were coordinated by Roopam Gupta, Morgan Facchin, and James Pye.
Visitors to Science Adventure at Cowdenbeath Leisure Centre on Saturday 2nd June enjoyed activities demonstrating light, microscopes, and optical trapping at our Seeing Life through a New Light event, as part of Fife Science Festival 2018.
Over 900 visitors at the Museum of Science and Industry, Manchester on Saturday 15th July enjoyed activities including the “Orange juice challenge”, making pin-hole cameras, performing pepper-oscopies, and learning about light, microscopes, displays, and optical trapping at our Seeing Life through a New Light event.
