2021 Andrew Chamblin Memorial Lecture

Andrea Ghez

Every year the Andrew Chamblin Memorial Lecture is given in Cambridge. Links to videos of past lectures can be found on the DAMTP website.

The fifteenth Andrew Chamblin Memorial Lecture, entitled "From the possibility to the certainty of a supermassive black hole", was given online by Professor Andrea Ghez, Nobel Laureate, at 5pm GMT on Wednesday November 3rd 2021. The film of the talk can be found here:




The Big Bang and Black Holes: In Celebration of Stephen Hawking's birthday

Two online public outreach lectures about the science of our Universe were delivered on Friday, 8th January 2021 by Professor Sir Roger Penrose, recipient of the 2020 Nobel Prize in Physics, and Professor Eiichiro Komatsu, Director of the Max-Planck Institute for Astrophysics in Munich. Sir Roger Penrose was one of Stephen Hawking’s earliest and most important collaborators, with whom he proved an all-encompassing theorem about how matter collapses to a singularity in both the Big Bang and Black Holes, that is, points in space where mass is seemingly compressed to infinite density and zero volume. Professor Komatsu played a leading role in the NASA WMAP satellite project that mapped the whole cosmic microwave sky for the first time, revealing a blueprint of the primordial seeds that Stephen Hawking had helped predict. Sir Roger and Eiichiro took us on a journey through space and time, looking forward to new insights from future experiments.

After the lectures a panel of young experts – postdoctoral fellows and PhD students – remained on the livestream to answer questions from members of the public.

Stephen Hawking 75 Public Symposium

A public symposium was held at Lady Mitchell Hall on 2nd July 2017 to mark Stephen Hawking's 75th birthday. The speakers were Brian Cox, Gabriela González, Martin Rees and Stephen himself. The event preceded a scientific conference entitled Gravity and Black Holes.

Films of the individual talks can be found here:

Brian Cox: Our place in the Universe

Gabriela González: Black Holes and Gravitational Waves

Martin Rees: From Mars to the Multiverse

Stephen Hawking: My Life in Physics


COSMO 2013

Brian Cox speaks at the COSMO 2013 Public Symposium.

Brian Cox speaks at the COSMO 2013 public symposium

The International Conference on Particle Physics and Cosmology, held in 2013 in Cambridge, is one of the major venues for interaction between cosmologists, particle physicists and astrophysicists. Cosmology is a data-driven field with new observations improving our understanding of the Universe. On Wednesday 4th September, as part of the programme, we held a popular event at Lady Mitchell Hall with three gifted science communicators who told us about recent developments which are impacting cosmology. Professor Andrew Liddle (Edinburgh) talked about the Planck satellite results announced this year about the cosmic microwave sky, Professor Brian Cox (Manchester) discussed recent discoveries at the Large Hadron Collider in Geneva, and Professor Stephen Hawking offered his own perspective on theories about the origin of the Universe, with a talk entitled "Fire in the Equations".

The State of the Universe

Lord Rees speaks at 'The State of the Universe': Stephen Hawking's 70th Birthday Public Symposium.

Lord Rees speaks at 'The State of the Universe': Stephen Hawking's 70th Birthday Public Symposium

On 8th January 2012, the CTC organised 'The State of the Univese'; a public symposium to celebrate Professor Hawking's 70th Birthday. Held at Lady Mitchell Hall on the University's Sidgwick Site, the symposium brought together four world famous scientists to give a series of popular science lectures.

Lord Rees, Professor Saul Perlmutter, Professor Kip Thorne and Professor Stephen Hawking spoke to a capacity crowd on topics ranging from black holes to the expanding Universe. Professor Hawking was not able to attend in person, due to ill health, but his speech, 'A Brief History of Mine', was read for him in absentia.

This symposium received worldwide print and media coverage, as well as an estimated 11,000 viewers live via an Intel Studio's streamed webcast.
