Nuclear-powered rockets
If we want to send humans to Mars, and launch more science missions to the outer solar system, then we need the firepower to get there. One technology that could usher in this new era is nuclear-propelled rockets. This video traces the history of the nuclear spaceflight concept and looks at two complementary approaches being developed today: nuclear thermal propulsion (NTP) and nuclear electric propulsion (NEP).

10 years of living with the Higgs boson
Просмотров 1,1 тыс.2 года назад
The 4th July 2022 marks the 10-year anniversary of that famous seminar at CERN when the Higgs boson discovery was confirmed. This short film revisits that historic moment in 2012 and also considers what the future holds for high-energy physics. After a fairly underwhelming subsequent decade, the particle physics community is once again energised as the large hadron collider has fired up after a...
The Human Organ Atlas: a ‘Google Earth’ for our bodies
Просмотров 1,9 тыс.2 года назад
Wouldn’t it be amazing to have a tool like Google Earth but for the human body, where you could zoom in from a full organ down to its cellular structures? That’s now becoming a reality thanks to the Human Organ Atlas project, and physics is key to this innovation. This short video explains how the Human Organ Atlas project emerged from the COVID-19 pandemic and how it could help medical scienti...

Trouble with young Hubble and how it was fixed
Просмотров 5494 года назад
Launched three decades ago, the Hubble Space Telescope is a triumph of the modern scientific era. But it wasn’t plain sailing from the start. David Leckrone - the mission’s senior project scientist 1992-2009 - speaks about the shock of discovering that the telescope’s optics were blighted by spherical aberration and how scientists and engineers banded together to work-out a solution. Leckrone’s...
