The talks can be given/watched separately in any order.

Fiat Lux III   (aka LSST)
The Large Synoptic Survey Telescope will survey many billions of galaxies, stars and planets and will address the most profound questions concerning our solar system, our Milky Way galaxy, and enigmatic dark matter and dark energy.

Fiat Lux IV   (aka Colour in the Cosmos)

Part four of the 'Fiat Lux' trilogy.

How we perceive colour is a complex mix of physics and physiology. We can see in colour because starlight (and hence sunlight) covers a spectrum of wavelengths. What can colours tell us about how the Universe works?
