Some time ago I received a call from a colleague. He was about to give a student a zero for his answer to a physics question, while the student claimed a perfect score. The instructor and the student agreed to an impartial arbiter, and I was selected.
I read the examination question: "Show how it is possible to determine the height of a tall building with the aid of a barometer." The student had answered: "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. The length of the rope is the height of the building."
The student really had a strong case for full credit since he had really answered the question completely and correctly! On the other hand, if full credit were given, it could well contribute to a high grade in his physics course and certify competence in physics, but the answer did not confirm this.
I suggested that the student have another try. I gave the student six minutes to answer the question with the warning that the answer should show some knowledge of physics. At the end of five minutes, he hadn't written anything. I asked if he wished to give up, but he said he had many answers to this problem; he was just thinking of the best one. I excused myself for interrupting him and asked him to please go on.
In the next minute, he dashed off his answer, which read: "Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, using the formula x=0.5*a*t^2, calculate the height of the building." At this point, I asked my colleague if he would give up. He conceded, and gave the student almost full credit.
While leaving my colleague's office, I recalled that the student had said that he had other answers to the problem, so I asked him what they were. "Well," said the student, "there are many ways of getting the height of a tall building with the aid of a barometer. For example,if the sun is shining you could measure the height of the barometer, then set it on end and measure the length of its shadow. Then you measure the length of the skyscraper's shadow, and thereafter it is a simple matter of proportional arithmetic to work out the height of the skyscraper.
"Fine," I said, "and others?""Yes," said the student, "there is a very basic measurement method you will like. In this method, you take the barometer and begin to walk up the stairs. As you climb the stairs, you mark off the length of the barometer along the wall. You then count the number of marks, and this will give you the height of the building in barometer units." "A very direct method."
"Of course. If you want a more sophisticated method, you can tie the barometer to the end of a string, swing it as a pendulum, and determine the value of g [gravity] at the street level and at the top of the building. From the difference between the two values of g, the height of the building, in principle, can be calculated."
"On this same tack, you could take the barometer to the top of the building, attach a long rope to it, lower it to just above the street, and then swing it as a pendulum. You could then calculate the height of the building by the period of the precession".
"Finally," he concluded, "there are many other ways of solving the problem. Probably the best," he said, "is to take the barometer to the basement and knock on the superintendent's door. When the superintendent answers, you speak to him as follows: 'Mr. Superintendent, here is a fine barometer. If you will tell me the height of the building, I will give you this barometer."
At this point, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.
The name of the student was Niels Bohr, who later received the Nobel prize for Physics.
‘Twas the night before Christmas and all through the trailer
Not a creature was stirrin’ ‘cept a redneck named Taylor.
His first name was Bubba, Joe was his middle,
And a-runnin’ down his chin was a trickle of spittle.
His socks, they were hung by the chimney with care,
And therefore there was a foul stench in the air.
From out in the yard there came such a noise
That Bubba got scared and rousted the boys.
There was Rufus, 12; Jim Bob was 11;
Dud goin’ on 10; Otis was 7.
John, George and Chucky were 5,4, and 3:
The twins were both girls so they just let them be.
They jumped in their overalls, no need for a shirt,
Threw a hat on each head, then turned with a jerk.
They ran to the gun rack that hung on the wall.
There were 17 shotguns; they grabbed them all.
Bubba said to the young’uns, “Now hesh up ya’ll!
The last thing we wanna do is wake up yer Maw.”
Maw was expecting and needed her sleep,
So out they crept out the door without making a peep.
They all looked around, and then they all spit.
The young’uns asked Bubba, “Paw, what is it?”
Bubba just stared; he could not say a word.
This was just like all of the stories he’d heard.
It was Santy Claus up on the roof, darn tootin’
But the boys didn’t know; they was about to start shootin’!
They aimed their shotguns and nearly made a mistake
That would have resulted in venison steak.
Bubba hollered out, “Don’t shoot, boys!”
That’s Santy Claus and he’s brought us some toys.
The dogs were a-barkin’ and a-raisin’ cain,
And Bubba whistled, and shouted, and called them by name.
“Down, Spot! Shut up Bullet! Quiet, Pete and Roscoe!
Git, Turnip and Tater and Sam and old Joe!”
“Git down from that porch! Git down off that wall!
Quit shakin the trailer, or you’ll make Santy fall!”
The dogs kept a-barkin’ and wouldn’t shut up,
And they trampled poor Pete who was only a pup.
Santy opened his bag, and threw out some toys.
Bubba got most, but left a few for the boys.
From up on the roof Santa heaved a great sigh.
Since the guns had been dropped he just might not die.
He jumped in his sleigh, told his reindeer to hurry.
The trailer started to wobble Santa started to worry.
Just as the reindeer got into the air,
The trailer collapsed, but Bubba didn’t care.
He was busy lookin’ at all his new toys.
Then a thought hit him, and he said to the boys:
“Go check on yer Maw, make sure she’s all right.
That roof fallin’ on her could-a hurt just a might.”
But Maw was OK, and the girls were too.
They fixed up the trailer; it looked good as new.
And as for Bubba, he liked Old St. Nick,
But Santa thought Bubba was a pure-in-tee hick!
Bubba had a nice Christmas, and the boys did, too.
And the Taylors wish a Merry Christmas to you!
