Javier De Elias Cantalapiedra from Madrid, Spain posted the YouTube video above to show his very elegant experiment in which he measured Planck’s constant using photons from a distant star. As in the e/m measurement he had previously shared with us, his experimental technique is very rigorous, which yielded Planck’s constant with just 5% error. This is remarkable given the method he applied.
Javier is an industrial engineer who works in the telecommunications industry. However, his passion is physics, which he pursues at a (very high) amateur level.
Thank you Javier for sharing!
