We understand the Universe around us primarily through light, and 16 May, #InternationalDayOfLight is special for those of us who love astronomy. Are you organising an online event around #IDL2020? Share it with us! @IDLofficial
Our understanding of light itself is closely linked with the history of astronomy, be it spectroscopy, wavebands outside the visible, interferometry, or even relativity. And astronomy owes many of its advances to technological innovations around light detectors in every waveband.

As promised a thread (17 tweets) with a selection of photos from the Live Science lecture last night. 200 students, 25+ demos & a team of 7 to setup. Thanks to @CocoLapre for the photos & a full list of thanks to everyone is at the end. First up dispersion & rainbows.
After breaking up white light, we put it back together. Great chance to talk about how flat screen displays work at this point.
Geometrical optics can be fun! Make a lens at home from a glass of water. A simple USB document camera allows you to project these experiments so everyone can see.
