Among the products our company sells is a non-toxic chelating agent, EDDS (ethylenediamine-disuccinic acid), typically sold as a purified salt in ammonia solution, see here. The main use of EDDS is to stabilize heavy metal ions in solution. We use it, for example, as an aide in electroless Palladium coating, to stabilize palladium ions, helping us produce a smaller grain, more continuous coat. The structure, shown below, is similar to that of EDTA (ethylenediaminetetraacetic acid), and the behavior is similar too. EDDS is more stabilizing in the presence of the other ions and we like that it is non-toxic.
Structure of EDDS, it binds metals by way of four OH groups. While each binding is weak, the total is strong.
The popular literature use for chelating agents like this is as a treatment for heavy metal poisoning by lead, arsenic, cadmium, nickel or copper. The TV series “House” featured patients with all these metal-poisoning problems, problems. Chelation treatment was important in Flint Michigan, 2015 when thousands got low-level lead poisoning and legionaries disease after the water department put insufficient phosphate and hypochlorite into the water and lead leached from pipes. Typically, EDTA is used for humans here, while EDDS is used by farmers and ranchers to treat animals. EDDS is less toxic, and removes fewer essential light minerals: magnesium, calcium, and zinc, so I’d think it would be better for humans too.
Effect of 300ppm SX-E in DI water, compared to standard DI water and acid wash. The biggest difference is with copper.
Our EDDS has been used to make cleaning solutions for silicon wafers, Sunsonix SXE, for example. Sunsonix SXE behaves as a soap, removing Fe, Cr, Ni, and Cu from solar cells, see reproduced figures at right. These metals will diffuse into surface of a silicon wafer, forming defects that absorb light and decrease solar cell performance by an average of 0.28%, see below.
Solar cell efficiency improvement with EDDS washing from a baseline of 16%. Occasionally 1.65% improvement was seen, but 0.28% on average
This is, based on a baseline efficiency of 16%. For more details see “Surface Contamination Removal from Si PV Substrates Using a Biodegradable Chelating Agent and Detection of Cleaning Endpoints Using UV/VIS Spectroscopy” ECS Transactions, 41 (5) 295-302 (2011). See also this article in Wikipedia.
This is the normal treatment regime for solar cells
At a different pH, EDDS and EDTH are used in remediation of metal-contaminated soils, see here. This can be done ex-situ, with the soil taken out to an external site and then washed. Alternately, for less contaminated soils, remediation can be done in-situ with the chelating wash applied to the soil. Plants, like vetiver grass (Chrysopogon zizanioides) then extract the heavy metals, concentrating them in their leaves. EDDS is more suitable for this as it is biodegradable and shows a high extraction efficiency in mineral rich soils, see here for comparison to EDTA.
Moving to another area of extraction. It seems that EDDS or EDTA solutions can be used to profitably extract rare earth metals, perhaps sending them to plants before final concentration. A standard methods of rare earth extraction uses chlorine and high temperatures. Alternate methods use ion-exchange extraction of liquid-liquid extraction. I suspect that chelation treatment might turn out to be more effective and cheaper. The price of rare earths has risen in recent years as China restricts sales so that the need for a new source has become a national priority.
Innovation is the special sauce that propels growth and allows a country to lead and prosper. The current Nobel prize believe that innovation powered the Industrial Revolution, causing England to become rich and powerful, while other nations remained poor, weak, and stagnant. Similarly, Innovation, they believe is why 19th century Japan rose to defeat China, and propelled China’s 21st century rise. But why did they succeed when others did not. What could the leader of a country do to bring power and wealth through innovation. Improved education seems to help; all of the innovation countries have it, but it is not the whole. Some educated countries (Germany, Russia) stagnate. An open economy is nice, but it isn’t sufficient or that necessary: (look at China). That was the topic of this year’s, 2025 Nobel prize in economics to Mokyr, Howitt, and Aghion, with half going to Joel Mokyr for his insights, historical and forward looking, the other half going for economic modeling. I give below my understanding of their insights, more technical than most, but not so mathematical as to be obtuse the normal reader..
The winners hold that innovation, as during the industrial revolution, is a non-continuous contribultion caused by a particular combination of education and market opportunity, of theoretical knowledge, and practical, and that a key aspect is depreciation (destruction) of other suppliers. Let’s start by creating a simple, continuous function model for economic growth where growth = capital growth, that is dK/dt. K, Capital, is understood to be the sum of money, equipment, and labor knowledge, and t is time with dK/dt, the change in K with time modeled as equal to the savings rate, s, times economic activity, Y minus a depreciation factor, δ, times capital, K.
growth = dK/dt = sY − δ K.
Innovation, in the Howett model, is discontinuous and accumulative. It builds on itself.
For the authors, Y = GDP + x, where x is the cost of outside goods used. They then claim that Y is a non-linear function of K, where K is now considered a product of capital goods and labor K = xL and,
dY/dK = AKα + γ where 0< α <1, and where γ is the contribution of innovation and/or depreciation. The power function, as I understand it, is a mathematical way of saying there are economies of scale. The authors assume a set of interacting enterprises (countries0 so that the innovation factor, γ for one country is the depreciation factor for the other. That is, growth and destruction are connected, with growth being a function of monopoly power — control of your innovation.
According to the Nobel winners, γ is built n previous γ as shown in the digram at right. It can not be predicted as such, but requires education and monopolistic power. The inventor-manufacturer of the typewriter has a monopolistic advantage over the makers of fountain pens. Innovation thus causes depreciation, δ K as one new innovation depreciates many old processes and products. If you add enough math, you can derive formulas for GDP and GDP growth, all based on factors like A and α, that are hard to measure.
GDP = α(2α/1−α) (1-α2)A L,
Thus, GDP is proportional to Labor, L and per-capita GDP is mostly an independent function related to economies of scale and the ability to use capital and labor which is related to general country-wide culture.
The above analysis, as I understand it, is in contrast to Kensyan models, where growth is unrelated to innovation, and where destruction is bad. In these Kenysean models, growth can be created by government spending, especial spending to maintain large industries with economies of scale and by spending to promote higher education. The culture preferred here, as I understand is one that rewards risk-taking, monopoly economics, and creative destruction. Howitt, and Aghion, importantly codify all this with formulas, as presented above that (to me) provide little specific. No great guidance to the head of a country. Nor does the math make the models more true, but it makes the statements somewhat clearer. Or perhaps the only real value of the math is to make things sound more scientific see the Tom Lehrer song, Sociology.
This insight from movie script by Grham Green suggests to me that progress may not be the greatest of advantages, perhaps not even worth it.
This work seems more realistic, to me, than the Keynesian models Both models are mathematically consistent, but if Keynes’s were true, Britain might still be on top, and Zambia would be a close competitor among the richest countries on earth. Besides these new fellows seem to agree with the views of Peter Cooper, my hero. See more here.
Writing all this reminds me that the fundamental assumption that progress is good, in not necessarily true. I quote above a line that Orson Wells, as Harry Lime, ad-libbed for the movie, “The Third Man.” Lime points out that innovation goes with suffering, and claims that Switzerland had little innovation because of its stability. Perhaps then, what you really want is the stability and peace of Switzerland, along with the lack of domination and innovation. On the same note, I’ve noticed that engineering innovators often ruin themselves dining in ruin, while the peaceable, stable civil engineers live long pleasant lives of honor.
Robert Buxbaum, November 16, 2025. A note about Switzerland is that was peaceful and stable because of a strong military. As Publius Vegetius wrote, Si vis pachim para bellum (if you wish of peace, prepare for war).
This post was inspired by articles like the one below asking how it was that some Americans, MAGAs think Trump is good when everyone of value sees him as a fat, bigoted, criminal clown. The Atlantic’s answer is they’re detached from classic ideals of good or moral, and are now fueled by “narcissism, fanaticism, and authoritarianism”. I thought a more helpful explanation was that we’re going through a paradigm shift, perhaps progressing in our thought of what it means to be good.
Consider Thomas Kuhn’s analysis of scientific progress. Tomas Kuhn was a major American Philosopher of the 1960s-70s who claimed that science progress was not uniform but included long periods of “normal science” punctuated by change. A “crisis” leading a “Revolution” resulting in big changes in language, outlook and thinking, a “paradigm shift”. In the midst of these scientific revolutions, the experts of the old system fight bitterly against the new while being confounded by the fact that it seems to work.
Consider the resistance to relativity and quantum mechanics. Before 1905 the experts were doing fine: Professors taught and students learned — formulas, tools and techniques were handed over. Educated had respect and money, and could communicate. There were some few contradictions, as in why the sun burned hot, or why the sky was blue, but one could ignore these. You knew who the experts were, and they didn’t include Einstein, Bohr, Pauli, Plank.
Democrats sell red hats and buttons with Fascist or Felon because Trump’s red MAGA (Make America Great Again) hats work for him.
But then came a few more problems, (inconsistencies in Kuhn-speak: radioactivity, photoelectrons, the speed of light… Einstein published on them in 1905, thoughts that few took seriously: imaginary time was a fourth dimension at right angles to the others, etc. The explantations seemed mad and for 14 years after he published, Einstein could not get a university job — anywhere. By 1919 detailed experiments suggested he might be right on a lot of things. It lead to the rise of a new group of experts plus a loss of esteem for the old, and a bunch of crank explainers who were neither but flourished in the confusion.
Hate abounded; new weapons and cures WWI removed aristocrats and beards. A popular book a lecture series of the time was “100 scientists against Einstein.” There followed a lost generation with no clear foundation. It took 50 years to resolve confusion, but there developed new thought leaders, a new language, new standard formulas and books were sold, and we were returned slowly to “normal science” in a new thought paradigm.
I see the conflict of opinion surrounding Mr Trump as a crisis in political thought similar to the crisis in science thought 100 years ago. Polite discourse if gone, replaced by stunts and insults. The government is currently shut, with 40% federal workers, those whose jobs are non-critical, on unpaid leave. It’s a collapse, not of morals, but of language. Trump hopes to use the shutdown, I think, to show that most of these 40%, are not needed. If they are not needed, it reflects a big lack in government — actually a big bloat in government. You can see why the opponents of cuts see Trump as a fascist who uses “dog whistles” to motivate “his base”, there is a lack of communication and a fear Trump may be right too, I think. The experiment in smaller government is being run as I write, and Trump seems confident that some 400,000 federal workers are not needed. Are they? Instead of debating, we’ve got to violence: two attempts on Trump’s life so far, the main college debater, Charlie Kirk, shot dead. Appropriate, I think, is Bob Dylan’s, “Times are a-changing” and “something is happening here, but you don’t know what it is, do you, Mr Jones.”
Other questions are being worked out as we speak -sending chills through the old order: Are China and Europe “ripping us off,” by free trade and stolen technology? Are tariffs an answer. Canadian and European leaders deride these thoughts openly, but I notice that both Canada and the EU have put heavy tariffs on Chinese goods.
Another issue is respect for experts. The Atlantic bemoaned that Trump supporters don’t respect experts on health, climate, and education, but perhaps they are lying. The seas have not risen as expected. Some warming may be good, or better than the remedies. Even if RFK Jr.’s ideas are wrong it seems that science has become unreliable (irreproducible), and that elite colleges aren’t fair in their assessment, nor do they provide great value.
Eventually things will settle down; we will some day have polite discourse. In 40-50 years, I suspect we’ll agree that some tariffs are good and that Trump’s tariffs are either to high or low, We’ll think that the climate push to no nuclear power, was a mistake, as was the giant, Ivanpah solar farm). And we’ll be able to discuss it civilly. I hope the change in thought takes less than 50 years.
Robert Buxbaum, October 3, 2025 – we are now entering another physics crisis too, I think.
A Korean animated movie, K-Pop Demon Hunters, KPDH, just broke all-time record for most watched movie in the History of Netflix. It’s only 92 days old, and not a big-budget film with massive marketing, but it’s had over 314 million views so far, appearing on the most-watched list in 32 countries. Some Chinese movies have had more views, but these tend to be specific to China, with limited appeal elsewhere. KPDH has three songs in the Billboard 100 too, including golden at no.1, see official music video, 352M views for the music video. The last movie to have three songs in the Billboard top 100 was Saturday Night Fever, some 45 years ago. Other top Korean groups include Stray Kids, BTS, and Black Pink, they’ve had multiple #1 songs world wide of the last five years, and fill 50,000 seat stadiums regularly with seats going for $150. Here are Black Pink, filling a 50,000 seat stadium in Paris. If you read the US press, you’d hardly know these groups exist. BTS had a big hit during Covid called, “Permission to Dance,” a positive song during that grim period, danced e.g at the UN. Listeners noticed, the press did not. I think the press finds Koreans “anodyne”, that is, insipid.
Top movies of the last 20 weeks include two Korean offerings, Squid Game and K-Pop Demon Hunters
One thing that turns off the US press, is that Korean songsters and movies are less sexual, and less politically moralizing. The top Oscar awards go to political movies. At the Emmies, this year, we were told, “F*ck ICE, Free Palestine.” Similarly, Green Day, Eminem, and other western bands lead chants of F*ck Trump. The press takes this moralizing as intellectual, but I find it cheap and suspect it turns off many potential fans.
Director of Star Wars, Kennedy, promoting diversity.
A favorite moralizing of US movies is to show women who don’t need or want men. Frozen was like that, as was Encanto, Last Dragon, Moana… Star Wars was a top franchise that Disney made more feminist, writing basically every man as bad. Women were good, powerful, and inherently talented. Rey a main new character, grabs a light saber with no background or training, and uses it like an expert. It turns off men, then women stayed away too.
End kiss of Pirates of Penzance, the pirate prince and the major general’s daughter
We like to show black actors in white rolls too, though not white actors in black rolls. Hamilton was successful, and had black actors playing in every positive roll, white actors playing evil idiots. It was done again with 1776, less successfully. All the founding fathers are cast as women; Jefferson is black, bisexual, and pregnant. There’s a message somewhere. The upcoming movie about King Gustaf of Sweden has a dark-skinned actor playing the king. Why? We had a dark- skinned daughter of the major general, who bends the pirate over to kiss him, a dark skinned Snow White with most of the Dwarves normal height, a female She-Hulk, stronger than the original, who lectures the original (and us) about anger. Apparently, the idea is to highlight the difficulties powerful women face. Korean shows have casts that make sense to the plot, and no gratuitous reversals or sex. Did Oppenheimer need the many sex scenes? Did the suicidal love interest have to be written stronger than the main character?
Then there are the sequels: the Marvel universe includes 37 interconnected movies, Star Wars, 19, Batman 13. To get the full story, you have to see them all. So far, in 2025, only two of the major funded movies were original (one was Korean, Mikey 17). The others are all reboots or sequels with recycled plots and ever-bigger explosions. It all works until it doesn’t, then they make a reboot. Law and Order, 26 years old with 500 episodes.
Scene from Crash Landing on You. These two are in serious trouble.
Korean entertainment has series too, but much shorter and with fewer explosions. A TV series will have only 16-24 episodes and I’ve yet to see one with a mass-murderer. The Squid game, has had 13 episodes over 3 seasons. Some deaths, but not wholesale. A longer series, “Crash Landing on You,” 24. In it, a successful South Korean executive (female) is blown across the border to North Korea into the arms of a handsome, North Korean. No deaths. They could have gone on for years, but didn’t. People rewatch the original.
Other countries movies moralize too, like ours do, but they tend to be patriotic moralization, and anti gratuitous violence, not violent, anti-patriotic as in the US. Chinese TV shows present Chinese politicians as honest, they have praise for the Chinese schools and infrastructure, and regular invocations to respect the police. India moralization is similar, but more towards family order. Korean messages are in-between, with some crooked politicians, some violence, people with mental or emotional problems who evolve.
Robert Buxbaum, September 17, 2025. The industry has pushed back against criticism of their wokeness, claiming that the only folks turned off are the toxic fans: white, MAGA men, mostly, who hate diversity. They claim to be happy when such fans stay home and watch KPDH, or go buy $150 tickets to see Koreans sing in Korean.
I’ve been blogging now for 13 years on all sorts of things; there were jokes, essays, politics, science, hydrogen.. I find that many of them are still relevant, though I would change most of them if they were to be written today. My first post was against the very high Detroit, MI minimum wage that was supposed to help black folks, but that I claimed ruined their city and their lives, and basically guaranteed corruption. I’d get back to this topic every now and again, but he problem has moved to LA and Puerto Rico. The last few Detroit mayors have eschewed this scam, to the benefit of the city.
MY opinion on hydrogen is still very high, though my opinion of hydrogen cars has soured in the past few years. There is infrastructure, and the cars themselves have improved, especially the batteries. There is now a good argument to be made that EVs make sense, especially for those who own their own home and who travel more than 500 miles per week. Meanwhile the customer base for hydrogen cars is only as a range extender.
Arctic Ice last month. It’s shrunk slightly, but still there — and I think the shrinking is a benefit.
I wrote disparagingly about global warming, arguing that Al Gore’s, Nobel prize winning claims were vastly exaggerated.. The arctic was supposed to be ice free by 2015 according to 98% of experts agreed (it’s things like that the ding the credibility of experts). I’d also argued that warmer was better. I’m reminded of a quote from Ovid, a Roman author: “Omnia mutantur, nihil interit”. Everything changes, but nothing passes away. It’s not that I read Ovid regularly, but the quote had appeared, in a modified form, in the British comedy, “Yes Prime Minister.”
There is a new Pope now with words of hope — delivered, in English at White Sox stadium. This t seems like a big improvement. We have another war with Islam; different but the same, and continued issues with China. And I’m learning Latin via Duolingo. (Cum Duolingo, studeo linguae latinae.)
The Mythbusters dimpled Taurus, and a diagram meant to show how drag is reduced. On a golf ball, at low NRE, vortex separation is moved back to 110°, the mechanism on a car is different, I suspect.
The dimples on a golf ball reduce air-drag resistance, so why don’t we put dimples on planes or cars? Perhaps because it’s ugly, or that cars are much bigger and than golf-balls, so we expect the effect of skin effects to be smaller. Finally, a Reynolds number analysis suggests that dimples on cars should increase drag, not reduce it.
In 2009, the Mythbusters decided to test the conjecture. Hosts Jamie Hyneman and Adam Savage ran careful gas usage tests on a Ford Taurus that was first covered with smooth clay. They drove the car repeatedly (5X) on a track at 65 mph (about 100 km/h), and measured “slightly over 26 mpg,” 9.047 l/100km, a respectable value. They then carved dimples into the clay to simulate the surface of a golf ball. See picture at right, and put the removed clay into the trunk so there would be no decrease in weight.
Underneath a Porche GT4, smallish dimples.
They then drove the dimpled car over the same course, five times as before at exactly 65 mph, and found the car got 14% more mpg, 29.6 mpg, or 7.946 l/100 km. See video excerpt here. They considered it their most surprising Mythbuster episode.
As it happens, dimples had been put on some production cars, even before the episode. They are just located underneath where most people don’t see them. The VW “Golf” had dimples even before the episode, and the Porsche Cayman GT4 does today, see picture above left, but most experiments find little or nothing. Car dimples are typically smaller than those used on Mythbusters, so that may be an explanation. Dimples have been found to help on soccer balls (the stitching acts as the dimples), and bicycle wheels (less advantage).
PHYSICS OF FLUIDS 18, 041702 (2006) Mechanism of drag reduction by dimples on a sphere, Jin Choi, Woo-Pyung Jeon, and Haecheon Choia.
The graph at right shows the source of confusion for cars and the great advantage for golf balls. It’s a plot of the drag coefficient for smooth and dimpled golf balls, as a function of the Reynolds Number, where NRE = Vdρ/µ. In this formula, V is velocity, d is the diameter of the car, ball or whatever, ρ is the density of the fluid, and µ is viscosity. NRE can be thought of as the ratio of the inertial to viscous forces acting on the object. It’s a way of describing the combined effects of speed and size for different objects in motion.
We see, above, that dimples reduce golf-ball drag by more than 50%, but only at speeds/ Reynolds numbers that are much lower than for normal cars, NRE between about 4×104 and 3.5×105, as are typical of golf balls during play. A typical car at 65mph will have a NRE.CAR = 3×106, suggesting that there should be no advantage for dimples, or possibility a disadvantage, that dimples should increase drag. A side note one sees, above, is that it is only the dimples on the front of the golf-ball that reduce drag: other dimples do nothing. If one were to add dimples to high-speed trains and airplanes I’d suggest them only on the front, so far I have not seen them.
I think that the Mythbusters did a good job with their experiments, and find their 14% improvement significant. So why do so few other cars see and advantage. One thought I had was to note that the Ford Taurus is a remarkably round car, providing ample space for front dimples to help, most cars today are more angular. I also note that the production cars have smaller dimples, as on the Porsche, above. Then again, the Mythbusters folks may have made some non-obvious experimental error.
Robert Buxbaum, January 4, 2024. An important side issue in this is that Google’s AI was awful, a handicap in researching this article. It lies continuously and convincingly, and did so here. I’d asked it for the year of the episode, and the AI lied, and said 2012. I asked for the type of car, the AI said an SUV, and it gave a misdescription of the tests. Lying AIs appear as villains in science fiction, e.g. HAL of 2001 A Space Odyssey, now in real life.
Jewish tradition requires certain holy items that have to be written on parchment with kosher, opaque, black ink. These items are abbreviated, STAM, books of the Torah (Sifre Torah, in Hebrew), Philactaries (Tefillin in Hebrew), and Mezzuzos for the doorpost. To be kosher the ink must be made from kosher sources: plant matter, soot, water, and/or inorganic chemicals. That leaves a lot of options, and it is likely that black Sharpie would be kosher, at least after the fact. Ideally, the ink should wash off in water too, based on Numbers 5:23 (Also, Rambam, Hilchos Tefilin 1:4, and Shulchan Aruch, YD 271:6).
There are ancient recipes, and I decided to semi-follow one, using walnuts instead of the classic gall nut and copper vitriol instead of iron. The aim was an ink that’s dark, long lasting, compatible with animal-skin parchment, and dissolvable. Some vegetable inks rot or fade, and most iron-based inks become permanent, like paint, they do not re-dissolve in water. If you don’t want to go through all this, you can buy kosher iron ink, e.g. here, knowing that this ink isn’t ideal, but it’s the type most people use for the practical reason that it looks nicer and permanent is a comfort.
The classical recipes for STAM ink is based on using the shell of gall nuts, a tree-growth (not really a nut) found in the Mid-east. As an experiment, I’ve tried to make a respectable, kosher ink with walnuts instead. Walnut trees grow readily in the midwest. I collected a dozen walnuts with their husks from a tree near my home. The outer husk had been green originally, but had turned black by the time I picked them (mid November). Rather than extract the inner shell, I used the walnuts as I found them, and tried boiling them in denatured alcohol, and also in water. Boiling in alcohol didn’t work well, producing the weak ink shown below, left. Boiling in water (below right) produced a much darker liquid. I used this as the basis of my ink.
Boiling walnuts in water produced a dark liquid, walnut water.
I boiled walnuts in alcohol. The water-ink runs and isn’t dark.
The traditional recipe begins by boiling gall nuts in water to produce a brownish ink-wash that looks hardly darker than my alcohol-wash ink. You then add soot and “green vitriol”. Perhaps that is copper sulphate, or perhaps iron sulphate. Copper sulphate is a dark blue, while iron sulphate is a light green. With gall nut water, it turns out that iron vitriol works ‘better’, reacting with tannin in the gallnut water to make a nice, black color that becomes a permanent ink. When tried the two types of vitriol with my walnut water, I saw no color advantage to iron over copper, and no real color change.
I put the walnuts in a beaker as shown, nearly covering them with water, and put a piece of foil on top. The longer I simmered the darker it got. In the end, I left the mix on a hotplate, on low for nearly a day as shown above. The ink-wash, by itself is a reasonably good ink, as shown below left.
The traditional recipe that I’ worked off o’m modifying includes three more ingredients, so I experimented with them. These were vitriol, soot, and gum Arabic, in proportions shown below, in the form of a poem in Arabic written about 900AD. The first of these additions I tested was vitriol. I first tried copper sulphate, half as much as walnut water, and found that it darkens the color a little and makes the combination a bit thicker thought the ink is still watery. Copper sulphate is an antimicrobial too, so even without changing the color much, I imagined this was a worthwhile addition. I also tried making the walnut ink with iron sulphate. This makes the ink slightly darker too, perhaps, but not thicker. I have less confidence about iron’s antimicrobial properties, and there were concerns that it could harm a parchment over time. I also worried that it would make the ink permanent.
Ink made from walnut water, copper sulphate, and soot. Perhaps better?
The next ingredient was soot. It’s used to make the ink darker, and perhaps thicker. Traditional soot is made from burning olive oil. One collects the soot by placing a plate over the smoky oil fire. I tried a bit of this, but it was slow, and I had some chemically produced soot in my lab, bought from MER corp, leftovers from making buckminsterfullerene. I added as much soot as vitriol as in the poem below, and as expected found it increased the blackness of the ink. It also changed the texture, making the ink gritty and harder to write with. I had trouble dissolving the soot into the ink too, and apparently I’m not the first to have this trouble. Some suggested heating, and some suggested honey. I tried both, and heating helped more than honey. I also tried using a drop of dish soap. The result, above left, was blacker than the original, but the writing is not professional grade, IMHO. The ink does not write well, and it still doesn’t cover 100%. I moved on to the next ingredient, gum Arabica.
The mixing ratios in this poem are not exactly clear. The amount of soot is the same as of vitriol, and half that of gall, but is this the weight of the gall nuts, or volume, or the weight of the dried extract. I used volume of walnut water and volume of soot, and have the sense that this is too much soot. Also soot is messy and hard to dissolve; use gloves and a lab jacket. the soot does not come out easily.
My final ingredient is gum Arabic, the gum of the acacia tree. This seems to be used as a thickener. Gum Arabic is available in the US, on Amazon as an edible “candy”, so I bought some. It wasn’t expensive, but took about 10 days to get here. In the meantime, I tried honey as a thickener. It appears in some ancient recipes, but didn’t really help here, and left the page sort of sticky. Gum arabic is solider, so I hoped for for lasting product. When the Gum Arabic came, I found that it was solid, crystalline, with has hardly any taste. Maybe Arabs add sugar? I figure there might be a mystical advantage to gum Arabic since it comes from the Acacia tree, the type of tree used to make the Ark of the Covenant. My expectation was that it might also make the ink darker, and that it might help dissolve the soot.
As it happens, gum Arabic doesn’t dissolve in cold water. But it did dissolve in hot water if I mixed it in and stirred for 5 minutes. The gum helped dissolve the soot too; gum Arabic seemed to do a better job than honey in this respect. Once the gum ink dried it was nice and solid, with the dried letters standing off the page a bit; they’re raised letters, and I really like that. The ink was still sort of grainy, perhaps from the walnut bits. I then tried dipping a written on parchment into some water and found the ink-letters dissolved easily. My understanding is that the ink I’d made was highly kosher for STAM, but as a follow-up experiment, I’m carrying some inked parchment in my breast pocket to see if it rots or fades. So far, no change. Some samples of writing are at left. The upper words are with the iron-vitriol version (iron sulphate), the lower with the copper vitriol (copper sulphate). You can sense why scribes might prefer the iron ink.
Robert Buxbaum, December 22, 2024. Scribes of 2000 years ago used wooden pens, it seems, as feather quills and fountain pens hadn’t been invented. I used a wood pen on some samples above, made by carving a popsicle stick. The better-looking letters, and longer passages, were written with a metal, calligraphy “quill.”
Few people learn cursive these days with any skill or speed. It’s a shame. This is a form of traditional art and communication. Handwriting is a slower way of writing, that leads to a different type of letter or essay. The sentences are, typically longer, and the words more expressive because the experience of writing and reading cursive is more expressive than with text. The emotional state and energy of the writer comes through the cursive writing, because the writing itself is a form of creative art, adding to the words.
Send a letter or a post card, and you’ve sent a work of art. You’ve communicated words, or course, but far more than with a text or email. First off, there is the picture on the card. You bought that card, or took the picture. Then there is the art of how many words you use. Each letter is directed to only one person, not to 100 as with a text. As a result, people will keep your letter or card far more than they will not keep a text an email. It is more from you, and more to them. You are likely to put more (or different) things in: experiences and feelings that don’t go into an email or text-letter. The size of your writing communicates and even your cross-outs are part of a cursive communication. With email or text, there are no natural cross outs, and you can send the same letter to 100 people, so you write more blandly, with an eye for eventual reuse for someone else. A cursive note is intended for only one person, the one recipient, and this affects both the words, and the form of the words.
Cursive also lends itself to adding a small sketch or doodle. This becomes part of a personal part of the art in a way that does not fit with normal text. It’s calligraphy and conceptional art, an important part of education, and a continuation of western culture. In normal texts, some people have come to add emojis or GIFs, but these are nowhere near as personal or expressive. The cursive letter or note is personal and spicy. It’s an important art form, at least a valid an art form as any that could be taught in school, and it should be.
Robert E. Buxbaum, Sept 1, 2024. I’m running for school board, and like the idea of teaching basic knowledge as a foundation of creativity. One of these basics, I think, is cursive writing.
Donald Trump has a lot of signature behaviors, including his “America first” politics, his hair, his ‘tan,’ his way of speech, and his way of wearing suits. Half of America finds them attractive or at least OK, while the other half finds them super-unattractive. Trump seems to have a super-power, that there is no middle. Those who dislike him dislike everything about him to his policies to his clothes. Let Trump propose immigration control, and the opposition demands open borders. Let Trump propose tariffs, an ole Republican approach to diplomacy that is thought to bring in Jobs, and the opposition (even unions!) goes crazy for free trade.
Trump likes dark colors, long ties, long jackets, and long sleeves on his suits.
In the book “Fear”, by Bob Woodward’s first story is about folks on Whitehouse staff stealing Trump’s first tariff proposal from his desk in an effort to prevent it being signed. Whatever they thought of the tariff (it was not that weird, and didn’t do much) the fact that they stole it showed the dramatic reaction people have. In this case, folks who otherwise understood that they are there to serve the president, not to overturn his policies.
LeBron James in the Thom Browne, Anti Trump look. The pants are too short, as are the sleeves and jacket. Note the dull grey color and the short, dull-grey tie. The fellow behind him is dressed normal or Trumpish: dark clothes, long sleeves, bright, long tie.
In terms of fashion, the anti-Trump fever is to react against Trump’s choice of suits in dark colors, paired with bright ties that hang below the waist. The anti men’s fashion has moved to dull grey suits and short, grey ties. Trumps’s suits’s typically have extra-long long sleeves and long pant legs that hit the shoe-top. He likes long jackets too, that to me look vaguely like Lincoln’s. The fashion back-lash is men are wearing ridiculously short pants and jackets, with socks showing.
LeBron James, at right, is wearing a complete mens, anti-Trump look, likely a Thom Browne suit, a very expensive ill fit. This suit doesn’t look comfortable, but it’s fashion, and as I’ve said before, you’ve got to suffer for fashion.
There is also a woman’s version of anti Trump fashion. The Trump women wore feminine, closely fitting clothing and wore their hair long. The anti-Trump women’s look is the opposite; it includes short hair and masculine, often covered. This is paired with loose fitting male clothes: cargo pants or combat fatigues. Topping it off, ideally ideally is a checkered, keffiyeh scarf, either over the head or around the neck. The style of scarf was made popular by former PLO head, Yassar Arafat. This look is particularly popular on college campuses and at demonstrations. It implies that the wearer supports Palestine (Trump supported Israel), and shows you are part of the cool set. The wearer, herself, is typically is not in favor of kidnapping or rape or putting babies in oven, but they are so strongly anti Israel and Trump that they are OK with it, especially if it is Jews being kidnapped, rabed, or cooked alive. They will call for Jews to be gassed or tortured. It’s part of being in the in-crowd, and antisemitism is what’s in these days — it’s been popular for many centuries.

It is a misconception to think that those wearing the keffiye don’t understand that they would not live long if they had to dwell among the Arabs they support. These feminists do understand, as do the ‘Queers for Palestine’. They’d never want to live in even the most moderate Arab country, the same way that those supporting Mao would never want to live in China under Mao. It is fashion, and like all fashion, it’s a mob behavior that exists only for fashion’s sake. In this case there is the added advantage that you get to hit Jews and break their windows — something that is particularly attractive for feminist women, I notice; the majority of people at the Palestine protests are women.
