  Wood's Hole, Mass.

  Dear Ralph:

  I am returning herewith your applications for a National Research Fellowship, in order that you may fill in the blank space for a second choice of a place to work. My recommendation would be to select Harvard, with either Wilson or Kistiakowsky (or both). If you prefer, Minnesota with Crawford would also be satisfactory, in my opinion. I believe that it is wise to put down a second choice.

  I am sending my letter of recommendation under separate cover to the Fellowship Board.

  I am very glad to know that you are pleased with the work that you are now doing. I wish. that I had come along with the other members of the Division when the visit to Wood's Hole was made some time ago, but I could not get away from Pasadena to make the trip. I know that the work is valuable.

  Cordially yours,

  Linus Pauling

  P. S. There is something to be said for the point of view which Wilson expressed to you. I too think that you are coming to the time of life when you should settle down in what is essentially a permanent job. I think, however, that it would be all right for you to spend one year on a fellowship job, but not more.

  Dr. W. T. Astbury

  Textile Physics Laboratory

  Leeds, 2

  England

  Dear Astbury:

  Both Dr. Shaffer and I have been so busy during the last two or three years that we have not succeeded in getting our paper on the use of punched card machines in x-ray and electron diffraction calculations ready for publication; I am accordingly writing this letter in answer to your letter of November 8, instead of sending the reprints which you requested. We hope to finish preparing a description of this work for publication before long.

  The x-ray calculations and electron diffraction calculations are made with use of a sorter and an alphabetic tabulator. The eighty columns of the alphabetic tabulator are divided into twelve fields of six columns each and a field of eight columns which is used for the description of the calculation. The twelve fields of six columns each are used for carrying out simultaneous summations for twelve values of the angle argument. Our x-ray Fourier series punched cards come in packs of eleven cards, representing 126 values of the argument, covering one-quarter of a revolution at intervals of 0.002 revolutions. Sine and cosine functions up to the frequency of 36 are included in the table, and amplitudes of plus and minus 500, 400, 300, 200, 100, 50, 40, 30, 20, 10, 5, 4, 3, 2, 1, permitting, by combining several packs of cards, any integral amplitude from -1000 to +1000 for sine and cosine functions of any frequency within the range covered. The evaluation of a Fourier sum is made by packing out the appropriate packs of cards, rearranging them in the sorter in such a way that all of the first cards are together, all of the second cards, etc., and then passing them through the alphabetic tabulator, which sums the twelve columns, prints the twelve answers, resets itself to zero, and proceeds with the similar treatment of the next twelve values. A calculation is good to about four significant figures. There is a great saving of time over any other method of calculation with which we are acquainted.

  The great labor involved in this work was that of preparing the original master set of punched cards. I suggest that if you find it possible to make use of this method it would be far better for you to obtain a duplicate set of our cards than to do the work ab initio.

  We also have an extensive file of cards for use in electron diffraction calculations. The punched card machines have been found of further use in the solution of simultaneous equations.

  We would be glad to help you in any way that we can.

  With best regards, I am

  Sincerely yours,

  Linus Pauling

  December 6, 1943

  Dear Dad,

  I was very happy to receive your letter and the enclosure. Thank you very much. What with Christmas shopping to do I'm going to need all I can get.

  I have very bad news. I washed out of air crew training on the psychological interview. The psychiatrist decided that I was subject to too much nervous tension. This rejection was awfully disappointing to me. Apparently my other test were all right, although I'm not certain yet. I asked the flight surgeon, and he said that I could reapply for cadet training after I have proved myself in combat. Armoror's [sic] school takes nine weeks, aerial gunnery six weeks, so if things move along I can see action inside of a year. The sooner the better.

  Meanwhile, training proceeds as usual. Everyday some of the boys report to sign questionnaires and get their folders, and then they are happy because they are eligible for shipment to college. About fifteen of the original hundred of our group have washed already. Undoubtedly more will, since those that washed are deficient medically, and we had many stiff mental aptitude test that will show up faults.

  The psychomotor test was extremely interesting and a great deal of fun. All information concerning it is supposedly confidential, but I think you ought to hear about it.

  The first test was a board with rows of square holes in it and square pegs with round heads.

  They are turned 180 as rapidly as possible.

  The next test was a wheel with a spot in it. The wheel revolved, as we held a pencil to the spot and pressed one of two buttons with the other hand as two lights flashed.

  The third was a little machine with a wheel that contained a button that moved in a slot. A contact, operated by the handles shown, moved around over the wheel.

  The next was a board with lights. As combinations of lights flashed on, we pushed one of four switches.

  The fifth was a machine with rudder bar and joy sticks and a board with pairs of lights. A combination of green lights would flash on, and we matched the red one up with the controls.

  The last test was a small plane held in place by springs which were attached to a rudder bar. Our problem was to keep the plane balanced on a target.

  This psychomotor was like a penny arcade, and we enjoyed ourselves doing it. Give my love to mom and the kids

  Love,

  Linus

  December 10, 1943

  Dear Mom,

  I was happy to get your letter, as always. I received all six bucks in good shape. The little iron and the vitamins arrived safely. Thanks very much. Christmas shopping is going to be a problem for me, too. I'm going to stick to the PX for thing as the town is full of gyp-joints. I think that my present for the family will not be very magnificent. This army is going to do me good by teaching me how to get alone on very little money.

  I felt pretty low when I had to write Dad that I washed out. Another failure can be added to my long list.

  One of the boys in our barracks, a somewhat morose and introverted chap who washed out, took some poison in an attempt to commit suicide or to get himself discharged. We sent him off to the hospital and I haven't heard anything further.

  Joanie Newman mentioned the nice days you've been having. She and I correspond fairly regularly. Texas is much too cold for comfort. Six of seven of the boys have gone to the hospital with pneumonia. Some fun.

  I have a cold, a cough , and a sore throat. I don't know what I'm going to do about getting rid of all those.

  I'm on detail as a runner tonight. It's fairly easily; I get to sleep most of the time.

  December 11, 1943

  I managed to get four hours sleep. I don't' know whether I can get more, because activities begin good and early. A large bunch of guys just checked in for KP duty.

  6:15 am

  I just got back from chow. The rest of the boys have come in, waiting for transportation to the range. I hope I can get off to bed soon.

  12:30 P.M.

  I had 4 hours sleep in bed this morning. Now I suppose I go back for some more detail. I was extremely pleased to wake up and find the sun shining and soft music playing. It reminded me of home.

  Give my love to Dad, Pete, Linda, and Crellie.

  Love,

  Linus

  P.S. Pete, I am awfully happy to hear such good reports.

  Dear Paul:

  Don Yost has shown me your letter to him, and I am writing to say that while I was in Berkeley day before yesterday I learned that Fred Stitt would be interested in having a war job, and leaving the Regional Laboratory at Albany, California, for at least the period of the war. He is a very good man, and I think that you would find him useful. His salary, with overtime, is probably somewhere around $4500 now.

  We are all getting along well—Linus, Jr. is in the Air Corps in Texas now, with the rest of us at home. I hope that I get a chance to see you some time this spring when I come East.

  Sincerely yours,

  Dear Mom,

  I received the Christmas package from the kids and I am awfully pleased with it. I opened some of the things. Pete's dates were delicious. I couldn't resist eating them. The chain is extremely nice too. I'll write and thank each one.

  I mailed a package to Linda and Peter on the 15^th via Caltech. I hope it gets thru in time. I forgot to included Pete's belt though.

  Shopping is just about impossible here. I can't get into town while stores are open, and the Px's have a rather limited choice. Would you get a little something for Crellie for me? I failed completely to find anything suitable for you and Daddy.

  My health finally broke down completely. We spent Thursday on the range firing sub-machine guns and carbines. It was so cold that the ice stayed unmelted all day. On Friday I woke up with a 103 fever and acute nasopharyngitis (I think that's the name). I ended up in the hospital of course. Today my temperature is down to about 100. It feels good to be able to sleep as much as I want to.

  December 19, 1943

  Today I feel better. I ought to be able to get out of here in two or three days. I'm going to try and get a pass to go and see Mrs. Sturdivant on Christmas, but the chances are slim. I'll probably spend Christmas in camp.

  How do you manage with Sadie gone? It much be awfully hard on you. You shouldn't try to do too much.

  I don't know whether I should try to transfer to the medical department or to continue on with combat crew training. It will require further thought.

  I hope you have a happy holiday season with the family.

  Much love,

  Linus

  Dear Roger:

  I am not sure that I understand completely the problem mentioned in your letter of December 11, but I shall answer in the following way, with the hope that these answers are useful to you.

  1. I think that it might be proper, in one sense, to say that there is an interface between an exposed glucose residue or molecule and the aqueous medium. This interface would be effective so far as adsorption is concerned.

  2. The question as to whether the interface between the aqueous medium and the particle of starch with glucose attached is really an interface between medium and glucose or between medium and starch is a matter of words.

  3. I do not believe that the interface could be detected by radiation, because its dimensions are not great enough in comparison with the wave length of light.

  4. Adsorption phenomena would be affected by the glucose.

  With best regards, I am

  Sincerely yours,

  Dear Tom:

  I have read carefully the quotation in your letter of December 22 from the book "Philosophical Method" by Collingwood. I have never thought much about philosophy, and perhaps if I had a better background his statements would seen more to me.

  My interpretation of Collingwood's statements may be faulty because I can not tell from this brief excerpt from his writing what words he has taken to represent undefined concepts, and which words he has defined in terms of these concepts. It seems to me that Collingwood speaks very loosely: thus in his second sentence he says that ice, water, and steam differ both in degree, as hotter or colder, and in kind, as specifically different states of the same body; but in my opinion the second part of this statement has no meaning, since every difference between ice and water or water and steam is only a difference in degree: ice is less dense than water, it is harder than water, its vapor pressure is different from that of water, and so on.

  I do not understand what Collingwood means by the generic essence of ice, water, and steam, unless he refers to conservation of mass or to the existence of molecules. Modem physical scientists try to avoid talking about anything except experiments and experimental results. One experiment which may be related to the generic essence is that one gram of ice can be converted completely into one gram of water or into one gram of steam—whether or not this shows that ice, water, and steam have a generic essence is not clear to me. Ammonium chloride can be converted by heating into a gaseous mixture of ammonia and hydrogen chloride; I am not sure that Collingwood would say that solid ammonium chloride and the gaseous mixture of ammonia and hydrogen chloride have a generic essence in common or not. Collingwood's final statement about all three forms being equally forms of water, each fully entitled to that name and all it implies, means very little to me, in terms of experimental operations, because I do not know what the term water implies other than the properties of ice, water, and water vapor, and the fact that the three phases are interconvertible.

  If I were ever to be in an argument with anyone as to whether there is a change in the "generic essence" of H₂O on going from absolute zero to 100°C. I would require first that a definition of the term "generic essence" be given. So long as this term has not been rigorously defined discussion of it is a waste of effort.

  Dr. Campbell and I think that the copper sulfate method of determining serum protein might be useful in connection with our animal work; could you tell me the title of the Rockefeller Institute publication on this subject which you showed me, and tell me where we should write for a copy?

  I enjoyed my day with you very much, Please tell Mrs. Addis that I thank her for having me to dinner, and that, when I counted up my grams of protein for the day, I saw that I should have taken her advice in accepting the baked apple for dessert instead of pudding.

  Sincerely yours,

  December 31, 1943

  Dearest Mom,

  I was overcome by a veritable deluge of letters today. Zechmeister's books came today, too. I enjoyed them very much.

  I made a mistake by telling you I was sick. It was very foolish of me. Especially at Christmas time. I'm still in the hospital, but I haven't had any fever for over a week. The Red Cross is certainly magnificent. The women make life bearable by bringing books around to the wards. They furnished presents for everyone in the hospital. Christmas was really quite enjoyable even though I didn't go to see Mrs. Sturdivant. She sent me a very nice package of sugared pecans and dates with nuts in them.

  I can't see how you can run the house and work too. I'm worried about your overworking yourself.

  I'll tell the doctor about my susceptibility to Brights Disease in the morning. I am slightly worries about my inability to get rid of this cold, but I have noticed no symptoms of any kidney trouble. Perhaps it will get me out of the army (an idle dream, I'm afraid).

  I take a good shower every night when I'm in barracks, Not so often in the hospital. My face is not much worse, if any, than it was in Pasadena. Surprisingly I haven't gained any weight to speak of. Oh for my idle college days when I weighed 150 pounds! That's a good index of the amount of work I did. In the army I'm so tired that I sleep like a log from 9 to 5:30. In the hospital, of course, I sleep during the day, too, so my sleep isn't so deep.

  You mustn't worry about me, Mom.

  Your loving son,

  Linus

  P.S. I've been horribly lax about writing.
