The End of Our Sun

Our nearest star, that is the engine sustaining life on Earth, will one day run out of fuel. When this happens, the Sun will start expanding dramatically, forming a red giant and engulfing much of the solar system including the inner planets, vaporizing oceans; formerly icy planets will become habitable. Part of: Cosmic Conclusions This […]

The Surprising Uses of Conic Sections

https://www.gresham.ac.uk/sites/default/files/transcript/2022-04-25-1300_HART-T.pdf https://youtu.be/qFSN6XePEyw Conic sections – the curves made by slicing through cones at various angles – were studied by the ancient Greeks, but because of their useful properties, have many real-world uses. Planets have elliptical orbits, projectiles move in parabolas, and cooling towers have hyperbolic cross-sections. But did you know that one of the most […]

The geological record of climate change

Professor Christopher Jackson The Earth is warming, and dangerously so. But is this unusual? Have there been times in the past when the Earth has been very hot or perhaps, very cold? And if so, what caused this, and what did these changes in climate mean for life on Earth? In this talk Professor Christopher […]

Planetary Universe

Professor Katherine Blundell OBE How can new worlds be discovered, and how many exo-planets might be out there? What does today’s technology in astronomical observatories now enable, and what is it that holds us back from finding what is actually out there? What hinders us from pushing forwards the frontiers of space science? https://youtu.be/1GaeKxYbWYA This […]

The Beauty of Geometrical Curves

The path traced out by a given point on the rim of a circle as you roll it along a straight line is a beautiful curve called a cycloid, whose appeal to mathematicians has had it dubbed “the Helen of Geometry”. This curve is known in geometry as a roulette, which is a curve you […]
