Going Down

In antiquity Aristotle had taught that a heavy weight falls faster than a light one. In 1638, without any experimentation, Galileo saw that this could not be true. What had he realized?

Hidden Men

Shakespeare dedicated his sonnets to a “Mr. W.H.” No one knows who this was — his identity has remained a mystery for 400 years. Most of the sonnets are addressed to a young man, and some seem to contain puns on the names “Will” and “Hughes” (for example, sonnet 20 refers to “a man in hue all hughes in his controlling”), so the 18th-century scholar Thomas Tyrwhitt suggested that the young man was named William Hughes. Oscar Wilde took this up in his 1889 short story “The Portrait of Mr. W.H.,” in which he imagines that Mr. W.H. was one Willie Hughes, “a wonderful boy-actor of great beauty” who played women’s roles in Shakespeare’s company. Unfortunately there’s no evidence that such a person actually existed, though Samuel Butler discovered a real-life William Hughes who served as cook on a ship called the Vanguard in 1634.

In Ulysses, Mr. Best calls Wilde’s the “most brilliant” of all theories to explain the mystery. That’s ironic, because Ulysses contains a mysterious character of its own.

Things to Come

We can foresee the development of machinery that will make it possible to consult information in a library automatically. Suppose that you go into the library of the future and wish to look up ways for making biscuits. You will be able to dial into the catalogue machine ‘making biscuits.’ There will be a flutter of movie film in the machine. Soon it will stop, and, in front of you on the screen, will be projected the part of the catalogue which shows the names of three or four books containing recipes for biscuits. If you are satisfied, you will press a button; a copy of what you saw will be made for you and come out of the machine.

After further development, all the pages of all books will be available by machine. Then, when you press the right button, you will be able to get from the machine a copy of the exact recipe for biscuits that you choose.

— Edmund Callis Berkeley, Giant Brains, 1949

He adds, “We are not yet at the end of foreseeable development. There will be a third stage. You will then have in your home an auto­matic cooking machine operated by program tapes. You will stock it with various supplies, and it will put together and cook whatever dishes you desire. Then, what you will need from the library will be a program or routine on magnetic tape to control your automatic cook. And the library, instead of producing a pictorial copy of the recipe for you to read and apply, will produce a routine on magnetic tape for controlling your cooking machine so that you will actually get excellent biscuits!”

Theory and Practice

http://commons.wikimedia.org/wiki/File:Richard_Feynman_-_Fermilab.jpg

In 1982 Richard Feynman and his friend Tom Van Sant met in Geneva and decided to visit the physics lab at CERN. “There was a giant machine that was going to be rolled into the line of the particle accelerator,” Van Sant remembered later. “The machine was maybe the size of a two-story building, on tracks, with lights and bulbs and dials and scaffolds all around, with men climbing all over it.

“Feynman said, ‘What experiment is this?’

“The director said, ‘Why, this is an experiment to test the charge-change something-or-other under such-and-such circumstances.’ But he stopped suddenly, and he said, ‘I forgot! This is your theory of charge-change, Dr. Feynman! This is an experiment to demonstrate, if we can, your theory of 15 years ago, called so-and-so.’ He was a little embarrassed at having forgotten it.

“Feynman looked at this big machine, and he said, ‘How much does this cost?’ The man said, ‘Thirty-seven million dollars,’ or whatever it was.

“And Feynman said, ‘You don’t trust me?'”

(Quoted in Christopher Sykes, No Ordinary Genius, 1994.)

Metaphysical Necessity

In the early 1770s a writer signing himself Junius published a series of letters in the Public Advertiser, criticizing the British government. His identity was the matter of much speculation, so much so that Samuel Parr jokingly wrote to Jane Morsingale, “Madam, You are a very charming woman, and I should be happy to obtain you as a wife. If you accept my proposal I will tell you who was the author of Junius.”

The writer’s identity was never discovered, but suppose he was Sir Philip Francis, as is widely suspected. We would say that Junius necessarily is Francis. But this seems an odd kind of necessity: There’s no logical contradiction in the sentence “Junius is not Francis,” and the laws of physics don’t prevent the two from being distinct.

“There is a kind of necessity that is neither logical nor physical, namely metaphysical necessity,” writes Robin Le Poidevin in Travels in Four Dimensions. “When we say that something is metaphysically necessary, we do not imply that in denying it, one would commit oneself to a logical contradiction. Nor are we saying that it is required by the laws of nature. But we are saying that, in some fundamental sense, matters could not be otherwise.”

A related puzzle: Charles Dodgson made this entry in his diary on Nov. 8, 1897:

A letter came, addressed to ‘L. Carroll, Christ Church, Oxford.’ So many such now come, that I have decided to refuse them, and gave it, unopened, to Telling, to return to the Post Office. All such will now go back to the writers, through the Dead Letter Office, with endorsement ‘not known.’

If Charles Dodgson explicitly disavows being Lewis Carroll — then who is Lewis Carroll?

Alternative Energy

William Henry Brown’s The History of the First Locomotives in America (1871) describes two unlikely competitors that steam had to contend with on the Baltimore and Ohio Railroad. In the first, a horse was placed in the car and made to walk on a belt that drove the wheels. “The machine worked indifferently well; but, on one occasion, when drawing a car filled with editors and other representatives of the press, it ran into a cow, and the passengers, having been tilted out and rolled down an embankment, were naturally enough unanimous in condemning the contrivance.”

http://books.google.com/books?id=8sw_AQAAIAAJ

The second was a wind-driven car rather optimistically called the Meteor. This would run only when the wind was behind it, and the inventor “was afraid to trust a strong side-wind lest the vehicle might be upset; so it rarely made its appearance except a northwester was blowing, when it would be dragged out to the farther end of the Mount Clair embankment, and come back, literally with flying colors.”

“Like the horse-car, the sailing-car had its day. It was an amusing toy — nothing more — and is referred to now as an illustration of the crudity of the ideas prevailing forty years ago in reference to railroads.”

Surface Tension

Lewis Carroll on the perils of physics:

Suppose a solid held above the surface of a liquid and partially immersed: a portion of the liquid is displaced, and the level of the liquid rises. But, by this rise of level, a little bit more of the solid is of course immersed, and so there is a new displacement of a second portion of the liquid, and a consequent rise of level. Again, this second rise of level causes a yet further immersion, and by consequence another displacement of liquid and another rise. It is self-evident that this process must continue till the entire solid is immersed, and that the liquid will then begin to immerse whatever holds the solid, which, being connected with it, must for the time be considered a part of it. If you hold a stick, six feet long, with its end in a tumbler of water, and wait long enough, you must eventually be immersed. The question as to the source from which the water is supplied — which belongs to a high branch of mathematics, and is therefore beyond our present scope — does not apply to the sea. Let us therefore take the familiar instance of a man standing at the edge of the sea, at ebb-tide, with a solid in his hand, which he partially immerses: he remains steadfast and unmoved, and we all know that he must be drowned.

“The multitudes who daily perish in this manner to attest a philosophical truth, and whose bodies the unreasoning wave casts sullenly upon our thankless shores, have a truer claim to be called the martyrs of science than a Galileo or a Kepler.”

A Muddy Grave

http://en.wikipedia.org/wiki/File:Tyneside_Irish_Brigade_advancing_1_July_1916.jpg

Memories of the first day of the Battle of the Somme, July 1, 1916:

“Before the bombardment started and while everything was peaceful, I could see through my periscope a young Englishman playing his trumpet every evening. We used to wait for this hour but suddenly there was nothing to be heard and we all hoped that nothing had happened to him.” — Feldwebel Karl Stumpf, 169th Regiment

“As the gun-fire died away I saw an infantryman climb onto the parapet into No Man’s Land, beckoning others to follow. As he did so he kicked off a football; a good kick, the ball rose and travelled well towards the German line. That seemed to be the signal to advance.” — Private L.S. Price, 8th Royal Sussex

“For some reason nothing seemed to happen to us at first; we strolled along as though walking in a park. Then, suddenly, we were in the midst of a storm of machine-gun bullets and I saw men beginning to twirl round and fall in all kinds of curious ways as they were hit — quite unlike the way actors do it in films.” — Private W. Slater, 2nd Bradford Pals

“When the English started advancing we were very worried; they looked as though they must overrun our trenches. We were very surprised to see them walking, we had never seen that before. I could see them everywhere; there were hundreds. The officers were in front. I noticed one of them walking calmly, carrying a walking stick. When we started firing, we just had to load and reload. They went down in their hundreds. You didn’t have to aim, we just fired into them. If only they had run, they would have overwhelmed us.” — Musketier Karl Blenk, 169th Regiment

“Imagine stumbling over a ploughed field in a thunderstorm, the incessant roar of the guns and flashes as the shells exploded. Multiply all this and you have some idea of the Hell into which we were heading. To me it seemed a hundred times worse than any storm.” — Private E. Houston, Public Schools Battalion

“The sound was different, not only in magnitude but in quality, from anything known to me. It was not a succession of explosions or a continuous roar; I, at least, never heard either a gun or a bursting shell. It was not a noise, it was a symphony. And it did not move. It hung over us. It seemed as though the air were full of vast and agonised passion, bursting now with groans and sighs, now into shrill screaming and pitiful whimpering, shuddering beneath terrible blows, torn by unearthly whips, vibrating with the solemn pulses of enormous wings. And the supernatural tumult did not pass in this direction or in that. It did not begin, intensify, decline and end. It was poised in the air, a stationary panorama of sound, a condition of the atmosphere, not the creation of man.” — Anonymous NCO, 22nd Manchester Rifles

It would become the bloodiest day in the history of the British Army, with 57,470 casualties. “From that moment all my religion died,” recalled Private C. Bartram of the 94th Trench Mortar Battery. “All my teaching and beliefs in God had left me, never to return.”

Italian to Go

“[B]ecause of the nature of pasta dishes, it has not been practical to eat pasta products while strolling.” Patented in 1990, Nicholas Ruggieri’s “spaghetti sipper” solves this problem with a tidy, portable container:

A person eats the pasta by placing their mouth on the spout 23 or tube 13 and sucking up the pasta. When the desired amount of pasta is obtained, the person bites off the pasta and then consumes the pasta in the usual manner. When the pasta is cut, the pasta in the tube 13 or spout 23 is held in place by the pawl mechanism 14b, 24b. When the person wishes more pasta the sequence is repeated. By use of the pasta server 10, 20 of this invention a person can eat pasta while strolling and the like.

“To the pasta can be added as desired any of a number of sauces traditionally associated with pasta. These sauces typically enhance the lubricious properties of the pasta.”
