which books are already being attended to.”
“And what will you teach now? This probability? Would I understand it?”
“You would, but I won’t teach it until it’s published at least in English so that every student can obtain a copy. I intend to give regular lectures on complex variables at first, since that follows directly after calculus, which is already taught here? Yes? And also an introductory course in physics, which they teach in Grantville at the same time as calculus, so there are many here such as your good self who could follow it. There will be laboratory demonstrations to illustrate the principles and give evidence of their truth.”
“Oh, so? You follow our own Francis Bacon in this, that the nature of the world cannot be known by reasoning alone?”
“To be sure, and Master of Arts Charnock Fielder of Grantville High School as well, who I’ve heard to say in two sentences what the learned Bacon required entire books to convey.”
“And that is?”
“ ‘In science there is no authority. There is only experiment.’ ”
Richard wasn’t accustomed to being awakened by Doctor Comber. But then, the distinguished Thomas Comber-Doctor of Divinity, Master of Trinity College, past Vice Chancellor of the university, and Dean of Carlisle besides-wasn’t known to make a practice of waking mere lecturers, or even to take the trouble of ascending to a third-floor room.
“Good morrow, Leamington. The dean of the chapel has informed me that Master Ramsey just now went to practice at the organ, and encountered a student of yours asleep beside a guttering candle, by which he was fortunately able to see a large cannon ball on a cord swinging from the ceiling. Would you care to explain that? To the dean? And arrange to have it removed before the morning lectures?”
“Uff? Asleep? At once. My apologies, Dr. Comber.” He scrabbled for his clothing. Under his breath he muttered, “I hope he got the data.”
“And, Leamington? Attend me in my rooms after the second lecture. There are matters we must discuss.”
Richard knocked on John Rant’s door. In moments there was a stirring within, and the door opened to reveal a very disheveled and confused-looking B.A.
“Richard? There’s light in the sky! I wasn’t called.”
“Indeed. I’ve just now been told that Tom fell asleep during the experiment instead of calling you at midnight to take your turn recording the data. We are required to remove the apparatus at once. Dress and join me in the chapel, if you will. If we’re quick about it, we may even have time for some breakfast.”
“Yes, of course. I’ll be but a moment.”
Richard left at as rapid a walk as the dignity of a lecturer allowed.
During the first hour Richard attended a lecture. By ironic chance it was on musical scales, and the lecturer was Master Robert Ramsey, the chapel organist. He made no remarks beyond his recent inquiries into the startling notion of an equally tempered scale, in light of the ancient Greek modes, but his displeasure was clear enough by his posture and the dark glances he periodically cast toward Richard. Still, Richard managed to keep his mind on the subject at hand. Mostly.
The second hour went to giving a private lecture on vector calculus to several post-graduate students, who had made considerable inroads into the fragments of new mathematics that had reached the university during Richard’s absence. It was somewhat easier for Richard to keep his mind on that.
And then it was time to call on Dr. Comber in the master’s lodging at the north side of the Great Court. Richard knocked, then entered to see him seated at his writing table, by the big windows.
“Take a seat, Richard. I just want to capture one thought before it escapes…There.” Dr. Comber put down his pen and straightened in his chair. “Richard, you’ve annoyed two fellow members of this college for no good reason. The dean was most upset that you and your students hung that heavy ball in the chapel and set it swinging without saying anything to him first, or indeed to anyone who had reason to go into the chapel and could have walked into its path unaware. He’s responsible for keeping the place in good order and fit for services, lectures, and everything else that takes place there. He needs to know what goes on in his domain. As for Master Ramsey, he had a moment of fright, seeing that thing rush toward his ankles in the gloom.”
“I’m sorry for that, Dr. Comber. Still, no harm was done.”
“No, no harm, except to your own reputation. And that’s concern enough. You’re no longer some raw undergraduate, whose inevitable transgressions are to be corrected with stern admonishments and suitable penalties, and then forgotten. You’re well known throughout the university now, and there are those who look up to you. Your actions have real consequences-some mistakes may not be so easily undone. I had to assure the dean and the organist that you and your students were conducting some serious lesson, and not a midnight jape. I was correct, wasn’t I?”
“Yes, of course. It was a teaching experiment in physics, demonstrating the validity of certain mathematical predictions.”
“Good, as I expected. What, exactly, was this demonstration?”
“It was the Foucault pendulum. It’s one of the two classic demonstrations of the rotation of the Earth.”
Dr. Comber dropped his hand to the writing table in front of him and stared wide-eyed at Richard for a heartbeat or two.
“A demonstration of the rotation of the Earth? A classic demonstration?”
“Yes, first performed in public by the French physicist Leon Foucault in the other history, in 1851.”
Dr. Comber leaned forward with his hands flat on the table and gave a distinct impression of a bulldog. “ Do I understand you correctly? Is this a tangible demonstration that apparently settles the controversy between the Aristotelian and Copernican world models at one stroke? And you did this without telling me, or any other officer or senior fellow of this college? Which will now circulate by rumor, because we don’t tell students not to talk about their studies? And cause all manner of upset to scholars who’ve spent their lives studying this very question?”
Richard froze.
“Exactly. You didn’t think. You considered only the mathematics and natural philosophy, and how to present it to your students. Not altogether a bad thing. But now you need to think about your colleagues as well. You’ve told me and the fellows of your hopes to bring whole new fields of learning here. You wish others to take up these studies, and make the university greater in consequence? For that, you need not merely the acquiescence of your fellows, you need their wholehearted support. You won’t get it by discourtesy.”
Dr. Comber sat back, thinking furiously.
“What must be done now is to present this in a proper and respectful scholarly manner to the whole university, and quickly. But before any announcement, I need to fully understand it myself. I would like you to explain it to me. Completely. Now, I understand your time tonight is to be taken up preparing a lesson?”
“Yes, Dr. Comber.”
“And I’m heavily occupied for the next two days. Can you come here after Hall on Friday?”
“Yes, certainly.”
“Good. Come then with your notes and whatever else is needful to make this clear. I think I may ask Thorndike to join us; he’s spent a good deal more time on this new mathematics than I’ve been able to.”
Richard’s right hand trembled slightly. He told himself it wasn’t from nervousness; after all, he was a seasoned teacher long since. He sat up straighter and looked around the chapel. Nearly time. The seats were filling rapidly with fellows and undergraduates from all over the university. There were at least three heads of colleges. Well, the pendulum was rigged and secured at the start of its arc ready to release, and it wasn’t as if he’d never presented this material before.
The bell overhead rang the hour. Dr. Comber rose and walked to the lectern.
“Masters and presidents, fellows, and scholars, there has been considerable talk of late concerning the knowledge conveyed here from Grantville, in particular a demonstration that took place in this chapel a few nights ago. I’ve asked Scholar Richard Leamington to repeat that demonstration today as a university lecture. I believe this will be of great interest to many of you. Scholar Leamington, if you will.”
