It really didn’t matter if these professors spent only a few weeks a year on campus, or even if they never taught a class at all. The reputation category in university rankings is controversial. Reputation is certainly important. Ask any parents who are paying Harvard tuition for their child—they will tell you in no uncertain terms how important ‘‘reputation’’ is to them! However, schools with relatively low reputation rankings relative to their overall ranking (such as my own university, I hasten to add) often decry the arbitrariness of this criterion.

But I cannot divide 100\F by 50\F and draw the conclusion that 100\F is ‘‘twice as hot’’ as 50\F. ’’ Zero degrees on the Fahrenheit scale is an arbitrary point (just as it is on the Celsius scale), and ratios like this therefore do not make sense. Ratio data, as the name suggests, are like interval data, except that ratios do make sense. The Kelvin (\K) temperature scale (the ‘‘absolute temperature’’ scale) is a ratio scale. It has a natural zero because 0\K is the coldest possible temperature, absolute zero.

If a hull plate of a riveted ship contains a large crack, and something stresses the plate (a big wave hitting the ship, perhaps), then that one plate might break in half. But only one plate breaks—not the whole ship. In a riveted ship, it is very unlikely that a fast-growing crack will jump from one plate to the next—the crack simply stops at the edge of the plate. Because of the violence of its collision with the iceberg, the riveted hull of the Titanic was an exception. But the hull of a welded vessel such as a Liberty ship is essentially one giant plate.
