Breaking barriers with quantum physics | Dr. Shohini Ghose | TEDxNickelCity

This talk was given at a local TEDx event, produced independently of the TED Conferences. Dr. Shohini Ghose talks about how the laws of quantum mechanics may be harnessed to develop next generation computers and novel protocols like teleportation.

Shohini Ghose is an Associate Professor of Physics and Computer Science at
Wilfrid Laurier University and an Affiliate of the Perimeter Institute for Theoretical Physics.

She and her co-workers also made the first-ever movies of cesium atoms that demonstrate how the “butterfly effect” of chaos can impact quantum correlations or ‘entanglement’.

Dr. Ghose was awarded the prestigious Sera Bangali award for her contributions to science and she is also a member of the TED Fellowship for 2014. With much accolades and accomplishments, Dr. Ghose is also the founding Director for Wilfrid Laurier University’s Centre for Women in Science which aims to build a diverse community in science through research, action and communication.

She also recently co-authored the first Canadian undergraduate Introductory Astronomy textbook, which is now being used in several universities in Canada.

 

Origin of the Moon | The Royal Society

The origin of Earth’s moon has fascinated mankind for thousands of years and has received scientific attention for over forty years, building on the return of rocks from the moon and the growing understanding of planet formation. The central idea of a giant impact on Earth is widely accepted and physically appealing but the constraints imposed by isotopic geochemistry, in particular, have proved daunting. Alex Halliday talks about an issue he has organised for Philosophical Transactions A that summarises the current state of our understanding and the challenges that still remain.

Harry Cliff: Have we reached the end of physics?

Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the biggest machine on the planet), we may never be able to explain all the weird features of nature. Is this the end of physics? Learn more in this fascinating talk about the latest research into the secret structure of the universe.
