Question: If you walk on a dry path between two walls a few feet apart, you hear a musical note or “ring” at each footstep. Whence comes this?
Answer: This is similar to phosphorescent paint. Once any sound gets between two parallel reflectors or walls, it bounds from one to the other and never stops for a long time. Hence it is persistent, and when you walk between the walls you hear the sounds made by those who walked there before you. By following a muffin man down the passage within a short time you can hear most distinctly a musical note, or, as it is more properly termed in the question, a “ring” at every (other) step.
Genuine student answer* to an Acoustics, Light and Heat paper (1880), Science and Art Department, South Kensington, London, collected by Prof. Oliver Lodge. Quoted in Henry B. Wheatley, Literary Blunders (1893), 175-6, Question 2. (*From a collection in which Answers are not given verbatim et literatim, and some instances may combine several students' blunders.)

Every occurrence in Nature is preceded by other occurrences which are its causes, and succeeded by others which are its effects. The human mind is not satisfied with observing and studying any natural occurrence alone, but takes pleasure in connecting every natural fact with what has gone before it, and with what is to come after it.
In Forms of Water in Clouds and Rivers, Ice and Glaciers (1872), 1.

Men thought dialectically long before they knew what dialectics was, just as they spoke prose long before the term prose existed

Pereant qui ante nos nostra dixerunt.
Can be variously translated as, “May they perish, who said first what we were going to say!” Or, could be used as “To the devil with those who published before us.” It is attributed to Donatus, because his pupil, St. Jerome, wrote about it (Ecclesiasten commentarius) as what “my master used to say”. Discussed in Notes and Queries (18 Jul 1868), No. 289, 27.

Science is founded on uncertainty. Each time we learn something new and surprising, the astonishment comes with the realization that we were wrong before.
In 'On Science and Certainty', Discover Magazine (Oct 1980), 58.

There’s no question in my mind that the capability of [the space shuttle] to put 65,000 pounds in low earth orbit—to put payloads up there cheaper than we’ve been able to do it before, not having to throw away the booster—will absolutely revolutionize the way we do business here on earth in ways that we just can’t imagine. It will help develop science and technology. With the space shuttle—when we get it operational—we’ll be able to do in 5 or 10 years what it would take us 20 to 30 years to do otherwise in science and technology development.
Interview for U.S. News & World Report (13 Apr 1981), 56.

We seem to be heading for a state of affairs in which the determination of whether or not Doomsday has arrived will be made either by an automatic device ... or by a pre-programmed president who, whether he knows it or not, will be carrying out orders written years before by some operations analyst.
In The Race to Oblivion, (1970), 232.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
