  2. Its origins are unclear, but we do know that by 1745, there was a thermometer at Upsala University with the Celsius scale we know today. 02:27

  3. Celsius was the first to establish which physical processes could reliably produce a fixed temperature. Past scales had used wildly unreliable standards. 04:28
