100 Years Ago On The Western Front

Link to original
100 years ago, the Battle of the Somme was winding down. The fighting lasted another week before both sides, exhausted, hunkered down for the winter.  Fighting resumed in the spring of 1917.

Conversations With Henry

Henry: God gave us thermodynamics but not kinetics!

Me: What do you mean?

Henry: I mean -- we can measure differences between where we are and where we've been, and also between where we are and where we'll be. Those things never change -- they're tabulated.

Me: But you're talking about free energy differences and chemistry....

Henry: Yes, of course...that too.


Henry: How things get from here to there is what we fight and argue's the kinetics!

I Have a Rendezvous with Death

 I have a rendezvous with Death  
At some disputed barricade,  
When Spring comes back with rustling shade  
And apple-blossoms fill the air—  
I have a rendezvous with Death
When Spring brings back blue days and fair.  
It may be he shall take my hand  
And lead me into his dark land  
And close my eyes and quench my breath—  
It may be I shall pass him still.
I have a rendezvous with Death  
On some scarred slope of battered hill,  
When Spring comes round again this year  
And the first meadow-flowers appear.  
God knows ‘twere better to be deep
Pillowed in silk and scented down,  
Where love throbs out in blissful sleep,  
Pulse nigh to pulse, and breath to breath,  
Where hushed awakenings are dear...  
But I’ve a rendezvous with Death
At midnight in some flaming town,  
When Spring trips north again this year,  
And I to my pledged word am true,  
I shall not fail that rendezvous.

Alan Seeger, 1888 - 1916
Seeger, a 28 year old American, was killed in action at Belloy-en-Santerre (The Somme) by German machine gun fire on July 4, 1916. He had joined the French Foreign Legion -- not because of enmity towards Germany but -- for his love for France. Seeger was the uncle of American folksinger and pacifist Pete Seeger.

The Somme -- A BBC Dramatization

The focus is on the Thiepval assaults on the first day. Not the usual lefty diatribe, there is plenty of blame to go around -- mostly for the men in trees.
The Somme: From Defeat to Victory challenges the traditional view of the battle as a disaster and reveals how it was on the Somme that the British Army learnt to fight a modern war.

The Somme Then And Now

The assault phase of the Battle of the Somme commenced 10 minutes after the blowing of the Hawthorne mine. The original black and white footage is from a full-length, silent documentary film, The Battle Of The Somme (1916).  That film has been digitized and set back to the original camera speed (something I worried about back here). Watch the original film here. It's lengthy, but worth it.

A couple years ago, two amateur filmmakers skilfully blended past and present cinematography. You won't realize what they've done for a minute or so but then it's incredible! The film is poignant too: Most of these men would be dead 40 minutes after this film was made.

Britian's Secret Terror Weapon At The Somme

100 years ago tonight, British engineers were secretly installing four 56 ft long, 2.5 ton machines called "Squirts" by their operators and "Judgements" by more senior officers. History calls them Liven's Large Gallery Flame Projector.

British Flame Projector. First used by British at the Battle of the Somme, 1st July, 1916. Range 40 to 50 yards. Oil was forced through pipes under pressure, and ignited at a jet.

Here is a British TV presentation of the weapon and its excavation at the Somme battlefield in France. Yes it was real and yes, they did find the remains.

The Chemistry of Politics

Politics and chemistry share many concepts and even words: coming together vs. falling apart; donor vs. acceptor; tipping point & transition state; polarized vs. neutral; vitriolic & caustic vs. neutral; litmus test; right vs. left; purity vs. impurity; structure & status quo vs. change & kinetics; majority vs. minority; and resonance to name a few off the top of my head. The words "electron" and "election" even look related but are in fact unrelated; electron comes from the Greek word for amber, while the word elect comes from the word to pick and choose.

Years ago, I hypothesized (and published with evidence) that a well-known (but poorly understood) chemical reaction was governed by repulsion: Electronic repulsion at its very core.  Briefly, a catalyst separately held the same substrate in two different ways; an incoming hydrogen molecule would then chose which of the two configurations to ride over the barrier hump while melding into stable products, corresponding to what could be dubbed right and left-handed versions of the same thing. Now, the rate of hydrogen's addition to (choice of) one of two configurations was the deciding factor; it was the deal clincher. Moreover, the two configurations were present in vastly unequal amounts from the start -- around a 10:1 ratio. Prior studies had shown that the incoming hydrogen preferred the minority configuration. That's where I came in. I said that incoming hydrogen was repelled by the major substrate-catalyst complex -- the one with the clingier hangers-on. In effect, I said that substrate binding (clinginess) killed reactivity by swelling a repulsive lobe on the catalyst.

A catalyst is rather like a politician. Its job is to bring us lowly substrates together to make something more stable. But just like my chemistry example, the favored politician with the clingier hangers-on can be the kinetic loser.  It's the repulsion, stupid.

The Last Letter From Stalingrad

[Long time readers of this blog will get what I'm up to again here. Over the past few years, I've rolled out a letter or two from the book "Last Letters  From Stalingrad." This year, I'm bringing the focus back to one in particular: Letter 39 in the series of 39 letters. I got my hands on a German language edition and have tweaked the translation and added footnotes to the original text.]

The following letter is from a young German officer on the front lines in Stalingrad, written to his father in the winter of 1942-43. The letter captures the break in the chain of command in the German General Staff. Before Stalingrad, unbroken generations of German Wehrmacht had defended their country and fought with professional honor (that they were politically betrayed at times is another matter). After Stalingrad, the esprit de corps would never be the same. The whole fighting spirit of the future German Bundeswehr died as well.
Dearest Father:1 
The division has been trimmed down2 for the big battle, but the big battle won't take place. You will wonder why I write to you and in care of your office. But what I have to say in this letter can only be said among men. You will transmit it to Mother in your own way. The word is out that we can write today.3 For one familiar with the situation that means that we can do it just once more.
You are a colonel, my dear Father, and a member of the General Staff.4 So you know what this means, and I needn't go into explanations which might sound sentimental. This is the end. It will last perhaps another week, I think, then the game is up.5 I do not want to look for reasons which one could marshal for or against our situation. The reasons are altogether unimportant and pointless. But if I am to say anything about them, it is this: Do not look to us for an explanation of the situation, but to yourselves and to the man who is responsible for it.6 Don't knuckle under7 --you, Father, and all those who think like you. Be on guard, so that a greater disaster8 does not overtake our country. The hell on the Volga should be a warning to you. I beg you, don't brush off 9 this experience.
And now on to the present. Of the whole division only 69 men are still of use. Bleyer is still alive, and so is Hartlieb. Little Degen lost both his arms; he will probably be in Germany soon. It is also the end for him. Ask him for any details you would like to know. D___ has lost all hope. I would like to know what he is thinking at times of the situation and its consequences. We still have two machine guns and 400 rounds of ammunition. One mortar and ten shells. Besides that, only hunger and fatigue. Without waiting for orders, Berg broke out with twenty men. Better to know in three days how things will end, than in three weeks. Can't blame him.
Finally, on to personal matters. You can be sure that everything will end decently. It is a little early at thirty, I know. No sentiments. Handshake for Lydia and Helene. Kiss for Mother (be careful, old man, think of her heart trouble). Kiss for Gerda, regards to all the rest. Hand to helmet, Father. First Lieutenant ____ respectfully gives notice of departure.
The original German has Liebster Vater! The usual way to greet a loved one in German would have been Lieber Vater or "Dear Father."  The author's use of the superlative, Liebster, instead of Lieber, or even Liebester immediately sets a familial tone to the letter.

2 The original has Die Division ist ausgeschlackt... which is much harsher than "trimmed down." Ausgeschlackt (infinitive: ausschlacken) means "cannibalized" or more literally, "butchered out."  The "trimmed down" translation sounds like an obese corps had been made fit; in reality a fit corps had been eviscerated.

3 Originally: Wir dürfen heute schreiben, heißt es bei uns: To us, that means we must write today.

4 Du bist Oberst: Army colonel. His father was a higher-ranked officer, but they were both professional soldiers.

5 The original idiom was: Dann ist der Kragen zu: "then the collar is closed."

6 He's referring to Hitler.

7 Originally, "greater disaster" was written as: Größeres Unheil. "Unheil" seems ironic in view of the well-known Nazi salute.

8 Originally, the idiom "don't knuckle under" was "halten die Nacken stief: keep the neck stiff.
This idiom rhymes with the last two lines of the letter.

9 Originally, the idiom "Don't brush off" was ...schlag deise Erkenntnis nicht in den Wind: don't strike this insight into the wind.
A key to understanding this ongoing series is here, and here. Each letter (39 in all) was written by a different and anonymous German soldier who knew he was going to die. I associate these letters with Christmastime for reasons explained at the links.

We Should Recognize Legal Legerdemain When We See It

According to Politico, the whole Paris Climate Treaty almost got hung up on parsing the difference between the words "shall" and "should."  Apparently, US lawyers threw a hissy fit over contract language invoking what America shall do vs. what America should do (full disclosure, I am no stranger to litigious battles over the meaning of single words in the context of intellectual property disputes). But, my interest is deeper: According to Politico, "shall" has a binding, obligatory legal meaning that "should" lacks (they're fighting over modals!). "Shall" would have meant getting the US Senate involved; "should" just means namby-pamby-only-while-Obama-is-in-office.  "America shall do this" was too serious for Kerry et al. and they insisted that it be changed to "America should do this."  In other words, '"should" is "shall-lite."  I call bullshit on that.

Consult any American or British lexicon and you learn that "should" carries the moral imperative that "shall" lacks.* Shall is more or less just a modal verb indicating future action.

Kerry et al. just morally obliged us to future actions.
* I'm still confused over whether "should" is the subjunctive form of "shall."  Any thoughts?

[added]  More on "should" here. And Victoria responded to me on Twitter!

Ten Years Gone

I've been on blogger for ten years. Not at this blog of course which I only started on a lark in 2009, but rather my time as chickenlittle, chickelit, El Pollo Real, and El Pollo Raylan. All most fowl. I told the story once of this chicken obsession. Link

The Loneliest Proton

No matter how hard you try you will never be able to grasp just how tiny, how spatially unassuming, is a proton. It is just way too small. A proton is an infinitesimal part of an atom, which is itself of course an insubstantial thing. Protons are so small that a little dib of ink like the dot on this “i” can hold something in the region of 500,000,000,000 of them, or rather more than the number of seconds it takes to make half a million years. So protons are exceedingly microscopic, to say the very least.  ~ Bill Bryson
That excerpt was blogged by Althouse without much further comment. The reader is supposed to recall from high school or college chemistry just how small the proton really is -- it is after all just a nuclear particle.

Protons cluster in every atom except for hydrogen where they appear alone.  In humans, protons mostly nucleate in groups of eight (as found in oxygen) or six (as found in carbon) with attendant neutrons, but they also go it alone in hydrogen.

Despite the proton's exceedingly tiny size in hydrogen, it is readily detected when placed in a magnetic field. They can even be spatially located in soft tissue by MRI. So there's a nice trade off. If only all the  smallest and hardest to see elements were so easy to detect.

Hydrogen is also giving us a glimpse into the mind as in MRI imaging of the brain.

From The Pink Into The Stink

I recently re-listened to Roger Waters' entire "The Wall."  I hesitate to call it Pink Floyd's "The Wall" because I believe the David Gilmour/Nick Mason/Richard Wright accounts that Waters became an intolerable control freak during that time and the final product was his and not theirs.

"The Wall" is nothing more than an apologia for unrestricted immigration both here but especially in Europe.

What triggered this? My viewing a biopic about Ginger Baker called "Beware Mr. Baker." It seems to me that both Baker and Waters became insufferable assholes because they both lost their fathers in the fight against fascism.

Who was it again who said that we become what we most hate?

We Could Use A Moore's Law For Rechargeable Battery Life

Well this is just cool...

Forgetful Scientists Accidentally Quadruple Lithium-Ion Battery Lifespan

Battery technology goes through periodic bouts of breakthroughs followed by long, long, periods of quiescence characterized by product development.

I like the article's focus on chemical elements -- lithium and aluminum.

I found this article while googling tips to conserve lithium-ion battery life.

The Physics of Storytelling

The living end of characters tells a story. As our eyes move from left to right across its sweep, the story's words leap translated into our imagination from start to finish. It's not just visual though. Read aloud, spoken stories too have living ends -- a beginning and an end heard just now.


An early physics pioneer you rarely hear about is Henry Moseley, who died 100 years ago today. Moseley made an important discovery now called "Moseley's Law."

Up until Moseley's time, chemical elements in the iconic Periodic Table were arranged according to weight. There was other rhyme and reason to the arrangement of elements in the Table, but no true understanding of their masses beyond: things get heavier. There was hope that atomic mass would reveal something fundamental about physics, and the 1914 Nobel Prize went to Harvard's T. W. Richards for his careful and methodical measurements of atomic weights.

Moseley showed that by shining X-rays onto atomic samples, he got a distinct integer value for each element which he called Z. Others before Moseley -- namely Bunsen and Kirchoff -- had shown how unseen atoms could be "seen" and identified by burning them in flames, but Moseley's experiments were beautifully simple and related all elements together with their Z-values instead of getting a unique "fingerprint" for each. Moseley's law is still used to identify elements in deep space.

Exactly what Z was had only been postulated a few years earlier. Niels Bohr had shown that Z was the nuclear charge (1 for the hydrogen atom) and Ernest Rutherford had suggested that Z for heavy atoms might be about half an element's atomic weight. A Dutchman, Antonius van den Broek had suggested--without proof-- that Z was an element's "atomic number." Moseley proved it.

Good ideas need good proof to become good science.

The Periodic Table was never the same after Moseley.

Henry Moseley probably should have gotten the 1915 or 1916 Nobel Prize in Physics, but he was killed by a Turkish bullet at Gallipoli at the age of 27.   
Henry Moseley (1887-1915)
Isaac Asimov wrote: "In view of what he [Moseley] might still have accomplished ... his death might well have been the most costly single death of the War to mankind generally."

Cold Gray Relics That Sparked A War For US

The remains of the RMS Lusitania lie on the sea floor off the coast of Ireland. The wreck is festooned with fishing nets and live mines which prevent fuller exploration:

SM U-20, the German sub that sank Lusitania, was stranded off the coast of Denmark in 1916. She was partially destroyed and abandoned by her crew. The wreck rusted there until 1925 when she was destroyed by the Danish government:

100 Years Ago On The Western Front

--Otto Dix Sturmtruppe gehen unter Gas vor (1924)
1915 was relatively quite on the Western Front. The action was at Gallipoli and the Eastern Front. After declaring war on each other the previous summer, the French and British allies fought the Germans through that first winter to an entrenched stalemate. The Western Front snaked from the Alps through France to the North Sea via Belgium. So horrendous was the scale of killing that at the trench level, both sides considered surrendering by Christmas 1914. link  But their leaders wouldn't hear of it. The following spring the grinding war resumed.

100 years ago this week, the small but once a powerful Belgian city called Ypres will mark a grim centenary: the first military use of chlorine gas.

Why Ypres?
The [1914] fighting at Ypres left the British saddled with a most unfavorable defensive position. It was a salient some six miles deep, with the town of Ypres [Ieper in Flemish] at the center of the base. The Germans held positions on low hills that gave them excellent observation over the entire salient. The area was so low that the construction of entrenchments was difficult, ground water being struck in many places at a depth of a one foot. A far better defensive position would have been one extending north and south just behind Ypres--giving up the salient and the town. Ypres, however, had become a symbol of Allied resistance; and the effect on public opinion of pulling back would have been unfortunate. Therefore, the troops held onto it, year after year. [1]
The Ypres salient hosted perennial WW I battles. The first was in 1914, then again in 1915, and last and worst of all, in 1917. But the second one--100 years ago this week--saw the first use of chlorine gas by the Germans.
On the morning of 22 April 1915 the Germans commenced to shell the Ypres salient. At 1730 a strange green vapor (chlorine gas) drifted toward the Allied lines from some 5,000 gas cylinders in the forward German trenches. The cloud engulfed the portion of the line held by some French Territorials and African troops, who promptly fled and left an undefended gap of over four miles. Not only did the Germans lack reserves to push through the gap but the darkness and the fear of their own gas by the German troops prevented them from realizing the extent of the rout. Even with only the few reserves available, the Germans could have accomplished more than they did. [2]
Chlorine gas had been known since 1630 or so. Sir Humphry Davy first recognized its elemental nature in 1810 and he was allowed to name it and he did so after its color: chloros: yellowish or light green (cf. chlorophyll). The use of chlorine as a bleach and a disinfectant dates back to the late 1700's. By the time of WW I, chlorine was being made on an industrial scale throughout the world. 

So why were the Germans the first to use chlorine gas in war? The French had used tear gas the year before.  One reason was an acute shortage of ammunition and a desire to end the carnage. The latter reasoning is essentially the same used to justify Hiroshima. But technological prowess and a dedicated mastermind also led its use as a WMD by the Germans.
Rudolf Knietsch's work at BASF before the war made it possible to liquefy chlorine using compressors lubricated with petroleum. [Fritz] Haber's idea, explained in detail to [Field Marshall Erich von] Falkenhayn and the top military leadership, was to put siphon tubes into steel cylinders, each containing about 20 kilograms of gas. These were then brought to the trenches, where they were positioned and buried in the ground at intervals of about one meter along a continuous front. A lead pipe was screwed into the opening of the cylinders, then brought up over the top of the trench and aimed in the direction of the enemy. When the wind direction was favorable, that is, blowing toward the enemy, all cylinders were opened simultaneously, and the chlorine was released. The liquid chlorine immediately turned into a gas and mixed with air, forming a yellow-green to white cloud containing about 0.5 percent chlorine at a distance of 50 to 100 meters from the cylinders. Since chlorine is two and a half times as heavy as air, this cloud rolled forward into the enemy trenches and foxholes and forced the enemy troops to flee their positions rapidly. The gas also damaged their weapons with corrosion. The German troops could follow the cloud and penetrate into enemy positions.[3]
Chlorine liquefaction was key because it allowed the transport and positioning of sufficient amounts of the latent gas. British and especially French industrial counterparts had no such capacity for producing liquid chlorine. British production went from 5 to 150 tons per week after Ypres.[4]

This map shows the geographic extent of the chlorine gas dispersion. The gas was released and rolled south across the French lines and towards the town of Ypres [Ieper]:

Link To Original
The hoped for result was to force the French troops out of their trenches and into marauding machine gun fire. In retreating however, the French soldiers simply moved back along with the advancing gas cloud and increased their exposure to its effects.

Both sides were unprepared for the consequences. The French had no protections in place. Within days and before the next gas attack on Canadian troops, word had spread that urine-soaked rags or cloth held against the mouth and nose afforded some protection: urea, a base, neutralized some of the HCl and HOCl.[5] As already mentioned, the Germans failed to follow through with troops.
Two days later the Germans gassed British and Canadian troops. Retaliation occurred in kind the following year.

Words In Drag

A student asked me to prepare a list of German/English cognate verbs; this is useful for building vocabulary. I've been at it for several hours.

Our verb "to drag" is rich in metaphor: dragging something; drag racing; drag queens; take a drag. In English, both verbs "to drag" and "to draw" are closely related.[1] In German, the related verb tragen is more limited: it means to wear, to carry, to bear, and has other supporting roles; they have another word for the basic idea of dragging, ziehen, which means to pull, to drag, to draw, to haul, etc.[2]

Here's the plausible origin of the term "drag race:"
Drag racing (1947), is said to be from thieves' slang drag "automobile" (1935), perhaps ultimately from slang sense of "wagon, buggy" (1755), because a horse would drag it. By 1851 this was transferred to "street," as in the phrase main drag (which some propose as the source of the racing sense). link
There is an old related word "dray" which meant a wagon for hauling stuff; a "drayman" was a "truck driver."

The origin of the term "in drag" is controversial:
Sense of "women's clothing worn by a man" is said to be 1870 theater slang, from the sensation of long skirts trailing on the floor (another guess is Yiddish trogn "to wear," from German tragen); drag queen is from 1941. link
The "dragging on ground" could be related to women's costumes being longer and having trains. The Yiddish origin sounds better, also given that the German word for costume is Tracht which in turn relates back to tragen.
