A physicist writes about optics, the history of physics, and old papers, covering topics like Faraday, Fizeau, and polar bear fur.
HN links it for its account of Faraday's 1851 experiments looking for a relationship between gravity and electricity.
Faraday actually did some experiments to try and show that Electricity and Gravity were related and in 1851 published On the possible relation of Gravity to Electricity in "Philosophical Transactions" of the Royal Society!

That would imply there could be devices that can create thrust with electricity. Faraday ran experiments to try to test this…in the 1800s.
