Oh, yes. "Current" and "Voltage" indeed are the same things, too.

Once I tried to order the PAL/SECAM convertor. They were trying to sell me a 220V/120V transformer instead. It was a sincere and complete misunderstanding.

It's marketing-speak.

Yes actually. I'm usually fairly successful with heat and temperature. The example of the air in an oven vs the roasting pan usually works fairly well. Whether it sticks for more than 1/2 hr is another question. Speed and velocity on the other hand.....

I do believe some people actually work to avoid knowledge, especially if it involves the physical sciences.

What's distressing is how many technical people don't seem to understand the difference.

A physics instructor many years ago explained it like this:

If you measure the temperature of a pan of boiling water 100 times and the standard deviation of the readings is 0.1 degrees, your thermometer is reasonably precise. If the mean temperature you measured is not 212.0 deg F, the thermometer is not very accurate. There followed a discussion of the factors that might affect the boiling temperature of water.

In other words: Precise instruments give you a consistent answer, accurate instruments give you the correct answer. You can calibrate a precise instrument at intervals to give you an accurate answer. It takes a bit more work for each measurment to get the correct answer from an imprecise instrument.

It's not only the man in the street. Even supposedly knowledgeable people have major disagreements as to mass vs. weight. Then you can compound the disagreement by trying to define force and/or impact.

This comes from the common practice of making scientific deinitions of common terms that turn out to me more precise than those terms. E.g., spiders are not bugs, whales are not fish, Pluto is not a planet.

I think you meant "spiders are not insects" - in general usage, even amongst biologists, spiders *are* bugs. Very technically, "bug" refers to the hemiptera insects (these are sap-sucking insects). But more commonly, "bug" refers to arthropods in generally - and that includes spiders, centipedes, and other such creatures. Lobsters and crabs are also arthropods, but probably not what most people mean by "bugs".

by "bugs".

mean by "bugs".

And in Maine. When I took a cruise on a schooner, the cook polled the passengers to find out how many "bugs" to cook for dinner. The bugs in this case were lobsters.

Scuba divers commonly refer to lobsters as "bugs".

The Chinese character for shrimp includes the "bug" radical.
