During WW2 wages were frozen by law and the only way employers could attract employees was not by higher wages, but by offering benefits as a non-cash kind of salary inducement. A bonus as it were. That is how Blue-Cross and Blue-Shield became the major players they became. Link to comment Share on other sites More sharing options...

Since molecular motion is somewhat random there is no definite length that can be assigned. The best we can do is specify a length interval. In nature nothing is at rest.

Do you mean like the mercury or alcohol in a thermometer? It varies with time. The precision of any measured length is limited by the nature of the measuring instrument.

The Heisenberg Indeterminancy Principle implies that we cannot get either the temperature or the length exactly. We have to settle for an interval. The very act of measure the length of a body causes the length to change a bit. I bet Ayn Rand did not know that.... Link to comment Share on other sites More sharing options...

The term "everyday" means not rigorously thought about. Everyday actions are for everyday people who don't think much and who don't think deep.

If you mean something needs to be at rest we know nothing is at rest. Heraclitus got that right. --Brant Link to comment Share on other sites More sharing options...

They can be bounded by an interval of some sort. What the interval is is a function of what is being measured, the surrounding physical conditions and the technology of the measuring devices.

Don't you hate it when there's some reddish blood around the bone? Spock. What does your tricorder show? It shows an interior temperature of 160 degrees. I suggest we leave it in the oven for another hour, Captain. Link to comment Share on other sites More sharing options...
