Imagine a set of people all living in the same building. Half of them think it is a hotel, the other half think it is a prison. Those who think it a hotel might regard it as quite intolerable, and those who thought it was a prison might decide that it was really surprisingly comfortable. So that what seems the ugly doctrine is one that comforts and strengthens you in the end. The people who try to hold an optimistic view of this world would become pessimists: the people who hold a pretty stern view of it become optimistic.

— C.S. Lewis, God in the Dock, 1970

Items that fell forward during the last moments of the Titanic, listed in Walter Lord’s A Night to Remember, 1955:

  • 29 boilers
  • 800 cases of shelled walnuts
  • 15,000 bottles of ale and stout
  • 30 cases of golf clubs and tennis rackets
  • 30,000 fresh eggs
  • 5 grand pianos
  • a 50-phone switchboard
  • 8 dozen tennis balls
  • a jeweled copy of the Rubáiyát of Omar Khayyám
  • 2 reciprocating engines
  • a 1912 Renault Type CB Coupe de Ville

Also tons of coal, a cask of china intended for Tiffany’s, dozens of potted palms, innumerable shuffleboard sticks, “tumbling trellises, ivy pots and wicker chairs in the Café Parisien,” and the ship’s enormous anchor chains, each link of which weighed 175 pounds. “Seen and unseen, the great and the unknown tumbled together in a writhing heap as the bow plunged deeper and the stern rose higher. The strains of ‘Autumn’ were buried in a jumble of falling musicians and instruments. The lights went out, flashed on again, went out for good.”

Hiatus

After 17 years, I think I’m going to take a bit of a break for a little while. I may post irregularly while I decide whether to continue.

In the meantime the blog archive and the podcast are still available. Thanks, as always, for reading!

P.S. Wow, thanks for all your kind messages! There are too many to respond to, but I’m reading every one. Thanks again!

Second Thoughts

Literary scholar Robert Hauptman calls this “marginal emendation run amok” — it’s a page from Henry James’ 1877 novel The American as James revised it anxiously for a new edition in 1907. He had decided the plot was unconvincing and asked for so many changes that two copies of the book had to be inlaid page by page on larger sheets to give him room to mark all the revisions.

On the last page, above, “James has partially or fully crossed out 16 of the 19 lines and rewritten the text for the definitive New York edition in the margins and at the foot of the page,” notes Hauptman. “His scrawling alterations cover virtually all of the generous white space and must be inserted in at least three different locations in the original text. Words are blotted out or struck in the new version, and as he approaches the bottom of the page, the lettering diminishes in size, because he realizes that he will run out of room.”

“The work on the earlier novels has involved much labour — to the best effect for the vile things, I’m convinced,” James had written to Grace Norton that March. Modern critics generally disagree — most editions today use the original version.

The Feynman Sprinkler

https://commons.wikimedia.org/wiki/File:Reaction_wheel.pdf

In the early 1940s a curious question began to circulate among the members of the Princeton physics department. An ordinary lawn sprinkler like the one shown here would turn clockwise (in the direction of the long arrow) as its jets ejected water (short arrows). If you reversed this — that is, if you submerged the sprinkler in a tank of water and induced the jets to suck in the fluid — would the sprinkler turn in the opposite direction?

The problem is associated with Richard Feynman, who was a grad student at the time (and who destroyed a glass container in the university’s cyclotron laboratory trying to find the answer).

In fact Ernst Mach had first asked the question in an 1883 textbook. The answer, briefly, is no: The submerged sprinkler doesn’t turn counterclockwise because counterbalancing forces at the back of the nozzle result in no net torque. Experiments tend to bear this out, although in some cases the sprinkler turns slightly counterclockwise, perhaps due to the formation of a vortex within the sprinkler body.
