If you accept that relative permittivity is a better term
Oh, I agree that relative permittivity is probably a better term, and it is even possible that I will get used to it in the 20 or 25 years I may have left in this life.? I did, after all, get used to saying "Hertz" instead of cycles per second (or cps), "megahertz" instead of megacycles, and gigahertz instead of kmc.? But it's tough to stop using a term you have used for decades, especially when everybody around you still uses the old term. I try to think in metric sometimes, and it's getting a little more comfortable -
very slowly.? Perhaps some time we will happen to be in the same country at the same time, and we can discuss it over a pint or two, which I understand is still the only legal measure used for beer in the UK.? In the meantime, remember:
“Science advances one funeral at a time.” - Max Planck
The switch to "relative permittivity" in the United States will probably go much as Mr. Planck suggests.
