Sir James Trowbridge No. 14 Berkeley Mews London
My dear James,
I'm sorry to have lost touch with you over the past few years; we haven't seen each other since the French War, back in 1948. Nine years! It doesn't seem it.
I'll tell you right off I want a favour of you. (No, I do _not_ want to borrow another five shillings! I haven't had my pocket picked again, thank you.) This has to do with a little historical research I'm doing here. I stumbled across something rather queer, and I'm hoping you can help me with it.
I am enclosing copies of some old letters received by Isaac Newton nearly three hundred years ago. As you will notice, they are addressed to "Mr. Isaac Newton, A.B."; it rings oddly on the ear to hear the great man addressed as anything but "your Grace," but of course he was only a young man at the time. He hadn't written his famous _Principia_ yet--and wouldn't for twenty years.
Reading these letters is somewhat like listening to a conversation when only one of the speakers is audible, but they seem to indicate another side to the man, one which has not heretofore been brought to light.
Dr. Henry Blake, the mathematician, has looked them over, and he feels that it is possible that Newton stumbled on something that modern thought has only recently come up with--the gravitational and light theories of the Swiss mathematician, Albert Einstein.
I know it's fantastic to think that a man of even Newton's acknowledged genius could have conceived of such things three centuries before their proper place in history, but Blake says it's possible. And if it is, Blake himself will probably do to Newton's correspondents the same thing that was done to Oliver Cromwell at the beginning of the Restoration--disinter the bodies and have them publicly hanged or some such thing.
Actually, Blake has managed to infect me with his excitement; he has pointed out phrases in several of the letters which tally very well with Einstein's theory. But, alas, the information we have is woefully incomplete.
What we need, you see, are Newton's letters--the ones he sent which provoked these answers. We have searched through everything here at Cambridge, and we haven't found even a trace; evidently the Newton manuscripts were simply discarded on the basis that they were worthless, anyway. Besides, records of that sort were poorly kept at that time.
But we thought perhaps the War Office did a somewhat better job of record-keeping.
Now, I realise full well that, due to the present trouble with the Austro-Hungarian Empire, the War Office can't take a chance and allow just anyone to prowl through their files.
It wouldn't do to allow one of the Emperor's spies to have a look at them. However, I wondered if it wouldn't be possible for you to use your connexions and influence at the War Office to look for Newton's letters to one of the correspondents, General Sir Edward Ballister-ffoulkes. You can find the approximate dates by checking the datelines on the copies I am sending you.
The manuscripts are arranged in chronological order, just as they were received by Newton himself. Of them all, only the last one, as you will see, is perfectly clear and understandable in all its implications.
Let me know what can be done, will you, old friend?
With best wishes, SAM Dr. Samuel Hackett Department of History

Mr. Isaac Newton, A.B. Woolsthorpe
Dear Mr. Newton:
It was very good of you to offer your services to His Majesty's Government at this time. The situation on the Continent, while not dangerous in the extreme, is certainly capable of becoming so.
Your letter was naturally referred to me, since no one else at the War Office would have any need for the services of a trained mathematician.
According to your précis, you have done most of your work in geometry and algebra. I feel that these fields may be precisely what are needed in our programme, and, although you have had no experience, your record at Trinity College is certainly good enough to warrant our using your services.
If you will fill in the enclosed application blank, along with the proper recommendations and endorsements, we can put you to work immediately.
Sincerely, Edward Ballister-ffoulkes, Bart. General of Artillery Ballistics Research Dept.

Mr. Isaac Newton, A.B. Woolsthorpe
My dear Isaac,
I am sorry to hear of your decision to remain at home for a while longer instead of returning to the College, but if you feel that your health is delicate, by all means rest until you are in better spirits.
I think, however, that you should attempt to return as soon as possible; you have a great deal of work ahead of you, my boy. Mathematicians--like Rome--are not built in a day--nor in four years.
If, however, you would like to do a part of your studies by post, I see no objection to it, under the circumstances, although, of course, it will be necessary to spend a part of your time in residence here, and the final examinations will have to be taken here.
Later on, when you are feeling better, I will send an outline of some work I intend to do on conic sections; I think it would be of great benefit to you to work with me on this. I have always had confidence in your ability. You are young yet, but, given time and plenty of study, you should make a place for yourself in the world of mathematics.
I think that the work I have in mind for you should prove stimulating.
Most sincerely, Isaac Barrow, Ph.D.

Dear Mr. Newton:
It would most certainly be quite convenient for you to do your work there at Woolsthorpe.
An explanation of the work we are trying to do and some of the problems we are up against will be despatched to you as soon as possible.
Sincerely, Ballister-ffoulkes

My dear Isaac,
Your paper has arrived. I haven't had time to look it over yet, but I shall find time to peruse it during the forthcoming holidays. I am, of course, very interested in what problems concerned you during the summer.
A very merry Christmas to you, my boy.
Is. Barrow

FROM: Ballistics Research Dept., British Army Artillery
TO: Isaac Newton, A.B., Woolsthorpe
SUBJECT: Ballistics research data.
ENCLOSURE: Range table sample for 9-lb. artillery.
2nd ENCLOSURE: Outline and general discussion of ballistics
1. In order to better understand the problems facing this Department, you will familiarise yourself with the enclosed material.
2. This material is confidential, and is not to be allowed to fall into unauthorised hands.
By order of the Commanding General
SECOND ENCLOSURE
The purpose of this project is to determine, with as great a degree of precision as possible, the range of artillery used by His Majesty's Armed Forces, and the methods of accurately firing upon targets at various distances from the cannon.
After a great deal of research, the following factors have been found to affect the distance which a cannon ball may be hurled by exploding gunpowder:
1. Weight of the cannon ball.
2. Weight of powder used.
3. Angle of elevation of cannon.
4. Length of cannon barrel.
The first two factors are obvious; the heavier the cannon ball, the more powder it will take to blow it a certain distance, and contrariwise.
The third is somewhat unwieldy to work with and definitely problematical in its effects. Up to a certain point, increasing the angle seems to increase the range, but after that point is reached, an increase in elevation decreases the range of the weapon. In view of this, it has been decided that all cannon will be fixed at the best angle for maximum range and the other factors varied to change the actual distance the cannon ball is fired.
(Here it may be noted, incidentally, that the angle of elevation is of no use in the Royal Navy, since that angle is indeterminate, due to the roll of the ship.)
The fourth factor, too, may be discarded, since a barrel of too great a length would make it unwieldy on the battlefield, although those of fixed fortresses could be somewhat greater. And, in view of the fact that changing the length of a cannon barrel on the field is out of the question, we may safely say that the fourth factor is a fixed quantity in each cannon and thus ignore it.
It has, therefore, been decided to test each of the various types of cannon presently in use by Army Artillery and publish for each a range table for various cannon balls and charges of powder, and to furnish a copy of such table to the battery leader of each field piece.
This programme, as may well be imagined, has required a great deal of cannon testing in the past year, and will undoubtedly require a great deal more before the project is finished. We hope, however, that it will be of at least limited use in the very near future, and will eventually greatly advance the science of cannon-firing.

2 January 1667
My dear Isaac,
Your Christmas was, I trust, a pleasant one? I hope your mother is in good health, and I hope your own is improved.
My dear boy, I have some advice for you; I do hope that you will take it as it is intended--as from an old friend and tutor who wishes you only well.
It has come to my attention that you are--shall we say--prostituting your talents. A friend of mine who works at the War Office tells me that you are doing some mathematical work by correspondence--something to do with cannon, I believe.
Now, I quite understand that you are in a somewhat precarious financial position, and believe me, I deeply sympathise with you. I know that the earning of a few pounds can mean a great deal to you in furthering your education.
I do not say that such work is menial, either. I would not have you think that I deplore your choice of work in any way; it is necessary work, and money is certainly necessary for life.
However, let me warn you: a simple task like this, which pays rather well, can become soporific in its effect. Many men of talent, finding themselves comfortably fixed in a mediocre position, have found their minds have become stultified through long disuse. _Please_, dear boy, don't fall into that trap; don't throw away a fine career in mathematics for the sake of a few paltry pounds. You are young and inexperienced, I know, and have a great deal yet to learn, so please take the advice of one who is somewhat older and wiser.
No, I haven't gotten round to reading your paper yet; I'll do it this evening, my boy, I promise.
Most sincerely, Isaac Barrow

My dear Isaac,
I read your paper, and I am, I must confess, somewhat nonplussed. What _are_ you doing?
I see that my letter of yesterday was somewhat premature; I should have waited until I had read your paper, since it is in exactly the same category.
You ask: "What is the optimum shape for a wine barrel? Should it be tall and thin, or squat and broad?"
And I ask: "What on Earth difference does it make?"
Surely you are not thinking of becoming a wine merchant? If so, what need is there to waste your time studying mathematics? On the other hand, if you intend to become a mathematician, why should you debase a noble and lofty study by applying it to wine barrels?
As I told you, I have no objection to your making a few pounds by doing minor calculations for the Army, but this is foolishness. You have gone to a great deal of trouble for nothing; as you gain more experience, you will realize the folly of such things.
As to your theory of "fluxions," I admit myself to be completely at a loss. You seem to be assuming that a curve is made up of an infinite number of infinitely small lines. Where is your authority for such a statement? You append no bibliography and no references, and I cannot find it in the literature.
Apparently, you are attempting to handle _zero_ and _infinity_ as though they were arithmetical entities. Where did you learn such nonsense?
My boy, please keep it in mind that four years of undergraduate work does not qualify one as a mathematician. It is merely the first stepping stone on the way. You have a great deal of studying yet to do, a great many books yet to read and absorb--books, I may say, written by men older, wiser, and more learned than yourself.
Please don't waste your time with such frivolous nonsense as toying with symbols derived from wine barrels. No good can come out of a wine barrel, my boy.
I hope you will soon find yourself in a position to aid me in some of the calculations on conic sections as I outlined them to you in my letter of the 28th December last.[1] I feel that this is important work and will do a great deal to further your career.
With all best wishes, Sincerely, Isaac Barrow

Dear Mr. Newton:
Thank you for your tabulations on the seven-pounder. I must say you were very prompt in your work; there was no need to work over the holidays.
Your questions show that you are unacquainted with the difficulties of manufacturing military arms; I am not at all surprised at this, because it takes years of training and practical experience in order to learn how to handle the various problems that come up. It is something that no university or college can teach, nor can it be learned from books; only experience in the field can teach it, and you have had none of that.
I can, however, explain our method of approach thus:
Each cannon to be tested is fired with several balls--some of iron, some of lead, some of brass, and some which have been hollowed out to make room for a charge of gunpowder in order that they may explode upon reaching the target. With each type of ball, we find the amount of powder required to drive the ball five yards from the muzzle of the piece; this is considered the minimum range. (Naturally, with the testing of hollow, explosive missiles, we do not fill them with gunpowder, but with common earth of equal weight. To do otherwise would endanger the cannoneer.)
After the minimum range is found, more balls are fired, using greater amounts of powder, added in carefully measured increments, and the distance achieved is measured off.
This process is kept up until the safety limit of the weapon is reached; this point is considered the maximum range.
Naturally, the weights of different balls will vary, even if they are made of the same metal, and the bores of cannon will vary, too, but that can't be helped. What would you have us do? Make all cannon identical to the nearest quarter-inch? It would not be at all practical.
I am happy to see that you are enthusiastic over the work we are doing, but please, I beg you, wait until you have learned a great deal more about the problem than you have done before you attempt to make suggestions of such a nature.
As to the paper which you enclosed with your tabulations, I am afraid that it was of little interest to me. I am a military man, not a mathematician.
Thanking you again for your excellent work, I remain.
Yours sincerely, Edward Ballister-ffoulkes, Bart.

9 January 1667 Cambridge
My dear Isaac,
I have known you for more than five years, and I have, I might say, a more than parental interest in you and your career. Therefore, I feel it my duty to point out to you once again that your erratic temper will one day do you great harm unless you learn to curb it.
You take me to task for saying to you what is most certainly true, viz.: that you are not yet a mathematician in the full sense of the word. You are young yet. When you have put in as many years at study as I have, you will understand how little you now know. Youth is inclined to be impetuous, to rush in, as the saying goes, where angels fear to tread. But better men than yourself have come to realise that the brashness of youth is no substitute for the wisdom of maturity.
As to your other remarks, you know perfectly well what I meant when I said that no good can come out of a wine barrel. To accuse me of sacrilege and blasphemy is ridiculous. You are twisting my words.
Please let us have no more of this name-calling, and get down to more important work.
Sincerely, Isaac Barrow

12 January 1667 London
Dear Mr. Newton:
Thank you again for your rapid work in tabulating our results. It is most gratifying to find a young man with such zeal for his work.
As I have said before, I am no mathematician, but I must confess that your explanation makes very little more sense to me than your original mathematical formulae.
As I understand it, you are proposing a set of equations which will show the range of any weapon by computing the weight of the ball against the weight of the powder. (Perhaps I err here, but that is my understanding.) It seems to me that you are building a castle-in-Spain on rather insubstantial ground. Where is your data? What research have you done on cannon-fire? Without a considerable body of facts to work with, such broad generalisations as you propose are quite out of order.
Even if such a thing could be done--which, pardon me, I take the liberty to doubt--I fear it would be impractical. I realise that you know nothing of military problems, so I must point out to you that our cannoneers are enlisted men--untutored, rough soldiers, not educated gentlemen. Many of them cannot read, much less compute abstruse geometrical formulae. It will be difficult enough to teach them to use the range tables when we complete them.
Indeed, I may say that this last point is one of the many stumbling-blocks in the path of our project. More than one of the staff at the War Office has considered it to be insurmountable, and many times I have fought for the continuance of the research in the face of great opposition.
I greatly fear that using any but methods known to be practicable would result in our appropriation being cut off in Parliament.
Again, however, I thank you for your interest.
Most sincerely, Ballister-ffoulkes

24 January 1667 Cambridge
My dear Isaac,
I am truly sorry I didn't get around to looking over your second manuscript until now, but, to be perfectly truthful, I have been outlining our course of work on conic sections, and had little time for it.
As it turns out, it was all for the best that I did so; it would have been sinful to take valuable time away from my work for such trivialities.
You are still harping on your wine-barrel fluxions and your Army cannon balls. Am I to presume that the whole thing is a joke? Or are you seriously proposing that the path of a cannon ball is related to the phases of the moon? That is rank superstition! Sheer magic! One would think that even a lad as young as yourself would have grasped the basic concept of the Scientific Method by this time.
How have you tested this absurd thing experimentally? Where are your measurements, your data? Your references?
Do not think, my boy, that fame and fortune in the sciences can be achieved by pulling wild hypotheses out of your imagination. There is no short-cut to mastery of a difficult subject like mathematics; it requires years of hard work and study.
As an example of what can happen when one has not learned enough of the subject, look at your own work. You appear to be handling Time as though it were a spatial dimension. You even end up, in several equations, with square seconds! Now, a yardstick will show that a foot up-and-down is the same as a foot East-and-West or a foot North-and-South. But where can you find a foot of time?
Please, dear boy, use your time to study the things you have yet to learn; don't waste it exploring a nonsensical cul-de-sac.
I will send you the outline on conic sections within the week.
Sincerely, Isaac Barrow

1 February 1667 London
Dear Mr. Newton:
In reference to your letter of 14 January 1667, on the simplified algebraic formulae for the prediction of the paths of cannon balls, our staff has considered the matter and found that not only is your mathematics incomprehensibly confusing, but the results are highly inaccurate. Where, may I ask, did you get such data as that? On what experimental evidence do you base your deductions? The actual data we have on hand are not at all in agreement with your computations.
Men with more experience than yours, sir, have been working on this problem for several years, and nothing in our results suggests anything like what you put forth. Finding data is a matter of hard work and observation, not of sitting back in one's armchair and letting one's mind wander.
It would, indeed, be gratifying if our cannon would shoot as far as your equations say they should--but they do not. I am afraid we shall have to depend on our test results rather than on your theories. It is fact--not fancy--which is required in dealing with military operations.
Sincerely, Edward Ballister-ffoulkes, Bart. General, Army Artillery
