Quotes About Diameter

To early American settlers, the primordial longleaf pine forests of the southeastern United States seemed an inexhaustible resource. Mature trees grew to heights of one hundred feet or more and diameters of as much as two feet

I prefer pi.

Chain consisted of an iron ring of about four inches diameter with six lengths of iron chain, each about a fathom long, welded on and wrapped tight to the bore of a thirty two.

Davidson was in the bows with the master's night-glass, a short telescope with lenses of a broader than normal diameter to collect all of the available light. In some circumstances the night-glass could be a useful aid.

Astronomy was full of such intriguing but meaningless coincidences. The most famous was the fact that, from the Earth, both Sun and Moon have the same apparent diameter.

the statement "All uranium-235 spheres are less than a mile in diameter" could be thought of as a law of nature because, according to what we know about nuclear physics, once a sphere of uranium-235 grew to a diameter greater than about six inches, it would demolish itself in a nuclear explosion. Hence we can be sure that such spheres do not exist. (Nor would it be a good idea to try to make one!)

Satellite datasets like WorldView can see objects as small as 1.5 feet in diameter. In 2014, WorldView-3 will be able to see objects a small as a foot.

That said, a fireball like the one hurtling towards us was worthy of the utmost respect. To adopt the jargon of commercial managers, this was a Premium-Class Fireball. Speaking in poetic terms, it was a Tsar-Fireball. A biologist would have said it was an Alpha-Fireball. As a cool, calculating mathematician might have remarked, it was a fireball with a diameter of about three metres. It was a fireball fearsome enough to make you shit yourself!

Many of their lodges remained as perfect as when occupied. They were made of poles two or three inches in diameter, set up in circular form, and covered with cedar bark.

Now, therefore, the Directors of the company are hereby ordered to see that precautions are taken to make travel on said railroad perfectly safe by using a screw with at least twenty-four inches diameter.

At rest, we know that its circumference is equal to p times the diameter. Once the merry-go-round is set into motion, however, the outer rim travels faster than the interior and hence, according to relativity, should shrink more than the interior, distorting the shape of the merry-go-round. This means that the circumference has shrunk and is now less than p times the diameter; that is, the surface is no longer flat. Space is curved.

This general flattening of objects that rotate is why Earth's pole-to-pole diameter is smaller than its diameter at the equator. Not by much: three-tenths of one percent—about twenty-six miles.

But it is the bane of psychology to suppose that where results are similar, processes must be the same. Psychologists are too apt to reason as geometers would, if the latter were to say that the diameter of a circle is the same thing as its semi-circumference, because, forsooth, they terminate in the same two points.

Now, therefore, the Directors of the company are hereby ordered to see that precautions are taken to make travel on said railroad perfectly safe by using a screw with at least twenty-four inches diameter.

The number ?, which is the ratio of the circumference of any circle to its diameter, is irrational, though this fact was not proved until 1768. Many other examples could be given.

There were four wheels under the panels, and the axles of the wheels were attached to the stand; each wheel was a cubit and a half in diameter.
