Description
Nederlands: Proefopzet ter bepaling van de weerstand van kwik, resulterend in de ontdekking in april 1911 van de supergeleiding beneden 4,2 Kelvin. Het bevroren kwik zit in een serie nauwe glazen capillairs die in de heliumcryostaat hangen, voorzien van elektrische toe- en afvoerdraden om spanning en stroomsterkte te meten. Natuurkundig Laboratorium, Steenschuur, Leiden. (Bijschrift uit de bron.)
English: Test design to determine the resistance of mercury, resulting in the discovery in April 1911 of superconductivity below 4.2 Kelvin. The frozen mercury is contained in a series of narrow glass capillaries hanging in the helium cryostat, equipped with electrical supply and drain wires to measure voltage and current.
