It was a perfectly casual accident, but, under the circumstances, it caused me a sense of mental shock as I instantly recognised the analogy to the skate. The barely hot enough, parallel sharp edge of the copper, pressed and pushed...

My research also led to the recognition that the property on which the lubricating action depends is the viscosity of the fluid, and that all fluids are lubricants, provided they are not corrosive. Air lubricates, as is shown by the floating of one true surface plate on another with perfect slipperiness. Now water had, at the time, not been recognised as a lubricant ; its viscosity is from...

The problem was discussed by Reynolds (1901), though with some diffidence, for he writes : ' On trying to remember whether I had heard of any attempt to explain the slipperiness of ice in any way — for I felt at the moment as though everyone was laughing at me — I found that I could not recall any mention of the subject.
