Black holes in space, seen by the Hubble Telescope, brought into space with hydrazine fuel, which was a byproduct of fungicides for French vines, fuelled by quarantine conventions and money orders, American Express and Buffalo Bill, Vaudeville and French battles, Joan of Arc and the Inquisition, Jews welcomed by Turks, who lost to Maltese knights with surgeons trained on pictures by Titian, in Augsburg, where goldsmiths made French money to pay for tobacco. That triggered logarithms and slide rules made by clock makers, who also made pressure cookers that sterilised French beer kept cool by refrigerators that were also used to freeze meat and chill down paraffin wax for making objects invisible.
