Ludwig, W. 1942. Agrometeorological population genetic contemplation. Unpublished poem by Wilhelm Ludwig, sent to Charlotte Boost ca. 1942.

Agrometeorological-population genetic contemplation von by W.L. (z. Z. auf einem Fliegerhorst.) Wilhelm Ludwig (At present on a military airbase) Frl. Dr. Boost zum Abschluss ihres 1.

Presumably my "type" can astound As seldom ' tis in the Wehrmacht found Die Häufigkeit hierfür sein q, Dir Rate der Enstehung u. Its frequency here is q With a mutation rate of u Das Gen dazu sei rezessiv, Sein Selektionswert negative (!). - Additionally recessive is the gene Its selective value negative Dann ist, sofern man weiss Bescheid, Nach den Betrachtungen von WRIGHT, Then as far as one knows for sure After the considerations of Wright q-1 gleich Wurzel minus s durch u,……….q-1=√ (-s/u) Und, wer, gebildet, überschlägt im Nu: the inverse of q equals the square root of s divided by u and, who educated is, estimates it an instant. Bei s = -1 und u sehr klein Muss (wie vorausgesetzt) auch q sehr niedrig sein:if s is minus one and u very small q also (as explained before) must be very low Jedoch - so fern es EUCH beliebt, Mein einstmals (!) EUCH gesandtes Manuskript However, in so far as it pleases you, The manuscript I once sent you Betreffend "Höhlen" doch (!) gelegentlich (!) zu lesen, IHR werdet finden, dass dort wesenConcerning indeed caves occasionally to read You will discover that there essentially Tlich andres gilt. So kann sum Beispiel Meinesgleichen Dort ganz enorme Häufigkeit erreichen, Other things apply. So for example types like me There can reach quite enormous frequency Allein auf Grund der Formeln FISHER-WRIGHT. (Dass solches zutrifft weiss ich wohl Bescheid.) Simply on the basis of Fisher-Wrights formulas. (That such is true I know for certain.) Da ferner ich und auch die andren faktisch Sind ganz erheblich negativ kasernotaktisch For moreover me and also the others actually Are quite extensively negatively barrack-o-tactic. Und ausserdem - gottlob! Noch spuren weise frontophob, And as well as that, thank God With traces of front-o-phobia Ist, wie in meinem Manuskript Sich Abschnitt Römisch III ergibt, It is as is stated in my manuscript On Section Roman numerals three (Gleichfalls auf grund von WRIGHT) Die Maximalwahrscheindlichkeit, Similarly on the basis of Wright The maximum probability Dass ich das Reichsamt oder Ahnliches verlasse, Voraussichtlich gering. Und das beruhigt mich. That I leave the government office or something similar is presumably small. And that comforts me. Ganz ausserordentlich.Ist dieses nicht ein veritable Beispiel für die Kraft Quite remarkably Is this not a veritable example for the power Der sogenannten - wenn auch von IHNEN oft verkannten - angewandten-Wissenschaft? Of the so-called - of often underestimated by you - the applied sciences. Literatur: 1) "Elegie" Archiv Seebenstr. 1 (1942a) 2) "Schwerer Entschluss" Herres Archiv 1 (1942b) More poetic (?) version. It seems my "type" can quite astound As in the Wehrmacht it is rarely found Its frequency there is a humble q With a mutation rate an even lower u. Indeed the gene for this is quite recessive With a selective value well in the negative. Then as far as one can deduce with delight Using the big equations of Sewall Wright, The inverse of q equals the square root of s over u For an intelligent man, it's then true That if s is less than one and u is small Then q itself to a low level must fall. However, you might be delighted to know, In the manuscript I once sent you to show, Concerning caves, if you actually did read, You will discover that there essentially indeed Quite other rules apply. Types like me Can reach enormously high frequency Simply from Fisher and Wright's stochasticity. (Which I know for certain is true as can be.) I and the others in this terrible duplicity Have strongly negative barrack taxicity. And as well as that, thank God almightier, It is tinged with traces of front-o-phobia. It is as is stated in my manuscript you see In section Roman numerals three That on the basis of Wright The maximum probability That I leave the government tonight is small, which comforts me. Quite remarkably Is this not a true example of the power Of the applied sciences - oft discounted by you - and their useful applicability
