The typical car has about 60 ft2 of exposed, non glass surface area, of which perhaps 2/3 is exposed to the sun at any time. If you covered the car with high-quality solar cells, the surfaces in the sun would generate about 15W per square foot. That’s about 600W or 0.8 horsepower. While there is no-one would would like to drive a 0.8 hp car, there is a lot to be said for a battery powered electric car that draws 6000 Wh of charge every sunny day — 6kWh per day– moving or parked — especially if you use the car every day, but don’t use it for long trips.
Owners of the Tesla sedans claim you can get 2.5 to 3 miles/kWhr for average driving suggesting that if one were to coat a sedan with solar cells, one day in the sun would generate 15 to 20 miles worth of cost-free driving power. This is a big convenience for those who only drive 15 to 20 miles each day, to work and back. As an example, my business is only 3 miles from home. That’s enough for the lightyear one, pictured below. The range would be higher for a car with a lighter battery pack, and some very light solar cars that have been proposed.
Lightyear one solar boosted plug in electric vehicle.
Solar power also provides a nice security blanket boost for those who are afraid of running out of charge on the highway, or far from home. If a driver gets worried during the day, he or she could stop at a restaurant, or park in the sun, and get enough charge to go a few miles, especially if you stick to country roads. Unlike gas-powered cars, where mpg is highest on the highway, electric vehicles get more miles per kWh at low speeds. It seems to me that there is a place for the added comfort and convenience of solar.
Some years ago I wrote a largely negative review of Brown’s gas, but the COVID crisis in India makes me want to reconsider. Browns gas can provide a simple source of oxygen for those who are in need. First, an explanation, Browns gas is a two-to-one mix of hydrogen and oxygen; it’s what you get when you do electrolysis of water without any internal separator. Any source of DC electricity will do, e.g. the alternator of a car or a trickle charger of the sort folks buy for their car batteries, and almost any electrode will do too (I’d suggest stainless steel). You can generate pressure just by restricting flow from the electrolysis vessel, and it can be a reasonable source of small-scale oxygen or hydrogen. The reaction is:
H2O –> H2 + 1/2 O2.
The problem with Brown’s gas is that it is explosive, more explosive than hydrogen itself, so you have to handle it with care; avoid sparks until you separate the H2 from the O2. Even the unseparated mix has found some uses, e.g. as a welding gas, or for putting in cars to avoid misfires, increase milage, and decrease pollution. I think that methanol reforming is a better source of automotive hydrogen: hydrogen is a lot safer than this hydrogen-oxygen mix.
Browns gas to oxygen for those who need it.
The mix is a lot less dangerous if you separate the oxygen from the hydrogen with a membrane, as I show in the figure. at right. If you do this it’s a reasonable wy to make oxygen for patients who need oxygen. The electrolysis cell can be a sealed bottle with water and the electrodes; add a flow restriction as shown to create the hydrogen pressure that drives the separation. The power can be an automotive trickle charger. You can get this sort of membranes from REB Research, here and many other suppliers. REB provide consulting services if you like.
In a pinch, you don’t even need the membrane, by the way. You can rely on your lungs to make the separation. A warning, though, the mix is dangerous. Avoid all sparks. Also, don’t put salt into the water. You can can put in some baking soda or lye to speed the electrolysis, but If you put salt in, you’ll find you don’t make oxygen, but will instead make chlorine. And chlorine is deadly. If you’re not sure, smell the gas. If it smells acrid, don’t use it. This is the chlorine-forming reaction.
2NaCl + 2 H2O –> H2 + Cl2 + 2NaOH
Ideally you should vent the hydrogen stream out the window, but for short term, emergency use, the hydrogen can be vented into your home. Don’t do this if anyone smokes (not that anyone should smoke about someone on oxygen). This is a semi-patentable design, but I’m giving it away; not everything that can be patented should be.
Fuel cells are highly efficient and hardly polluting. They have a long history of use in space, and as a power source for submarines. They are beginning to appear powering city buses and intercity trains, at least in Europe, but not so much in the US or Canada. The business case for fuel cells is that they provide clean electric power to the train or bus, without the need for overhead wires. Avoiding wires helps make up for the high cost of hydrogen as a fuel. The reluctance to switch to fuel cells is the US is due to the longer distances that must be covered. The very low volumetric energy density of hydrogen means you need many filling stations with hydrogen fuel cells, and many fill ups per trip.
Energy density CNG, hydrogen, hythane.
On a mass-basis, hydrogen is energy dense, with 1 kg providing the same energy as 2-3 kg of gasoline. The problem with hydrogen (aside from the cost) is that its mass density is very low, less than 50g/liter, even at high pressure. This is terribly un-dense on a volume basis. It would take 20 liters of high pressure hydrogen (about 5 gallons) to take a car or bus as far as with one gallon of gasoline. Even with a huge tank of high pressure hydrogen, 150 gallons or so, a cross country trip would require some 12 fill ups, one every 250 miles, and this is an annoyance, besides being an infrastructure problem.
Then there is cost. In California, hydrogen costs far more than gasoline, between $12 and $15 per kg. That’s ten times as expensive as gasoline on a weight basis and 4 times as expensive on an energy basis. What’s needed is a cheaper, more energy-dense version of hydrogen, ideally one that can be used in both fuel cells and IC engines, and the version I’d like to suggest is hythane, a mix of methane (natural gas) and 20-30% hydrogen.
Hythane dispenser
Hythane has about 3 times the volumetric energy density of hydrogen, and about 1/3 the price. It makes less CO and CO2 pollution because there is far less carbon. On an energy basis, hythane costs just slightly more than gasoline, and requires less infrastructure. Natural gas is cheap and available, delivered by pipeline, without the need for hydrogen delivery trucks. Because hythane has about three times the volumetric energy density of hydrogen, the tank described above, that would give a 250 mile ride with hydrogen, would give 750 miles with hythane. This means a lot fewer fueling stations are needed, and a lot fewer forced stops. As a bonus, hythane can be used in (some) IC engines as well as in fuel cells.
Hydrogen for hythane-automotive use can be made on site, by electrolysis of water. Because there is relatively little hydrogen in the mix, only 25% by volume, or 8% on an energy basis, there is relatively little burden on the electric grid, and fueling will be a lot faster than with battery chargers. Hythane is already in use in buses in China and Canada. These are normal combustion buses but hythane works even better — more efficiently — with fuel cells (solid oxide fuel cells) and thus hythane provides a path to efficiency and greater fuel cell use.
Hythane bus, Montreal.
Natural gas does not work as well in fuel cells; it requires a pre-reformer to make some H2, and even then tends to coke. To be used in most fuel cells, the methane has to be converted, at lest partially into hydrogen and this takes heat energy and water.
CH4 + H2O + energy –> 3H2 + CO
Reforming is a lot easier with hythane; it can be done within the fuel cell. Within a SOFC, the hydrogen combustion, H2 + 1/2 O2 –> H2O, provides heat and water that helps feed the reforming reaction and helps prevent coking. Long term, fuel cells will likely dominate the energy future, but for now it’s nice to have a fuel that will work well in normal IC engines too.
Part of the push to help the oppressed and save the plant is push to decrease the birthrate both in the developed and undeveloped world. Putting of childbirth is supposed to lead to a more meaningful life, while academic excellence is considered meaningful. Child-raising is considered male oppression of women, while writing mediocre poetry is, we’re told elevating, it’s finding your voice. It’s the new mood, at least in the developed world.
In the undeveloped world, political activism and wealth accumulation are presented as more meaningful, and fewer children is presented as a responsible route to wealth and happiness (see Indian advertisement below). My sense is otherwise, that children bring happiness and long term wealth. My sense is that the best two ways to change the world for the better is to work on yourself and to raise good children. And these Idas are connected; children are little mirrors, sometimes showing hidden flaws, sometimes revealing enthusiasm and greatnesses.
This month’s cover article of National Geographic includes economic justifications for fewer children and ecological justifications. Apparently we’re making life difficult for the polar bears. The assumption is that the bears like it cold, and their opinion is more important than that of animals that like it warm, like most humans.
There is also an assumption that there will be more jobs and better food if we have fewer children, or that people will be happier. Who are the “we” who are better off. I personally would not trade a billion randomly selected lives to lower the earth’s temperature 1 degree, or for the supposed happiness benefit of 1 million empty-nest households.
Old libraries and old books play a big part in the aesthetic.
The movie version of academia is typically a leafy campus, with great libraries, bright minds, and deep intellectual discussions. It’s a happy grove where the young and talented go to bloom to superiority, eclipsing their parents and their well-meaning, but fuddy-duddy teachers. It’s also where oppressed middle-agers go to complete a journey of self -discovery. To the extent that professors are there in older movies, it’s to confer degrees and, eventually praise.
But there is a new mood in literature and movies where professors are sinister, and competition is darker and more dangerous place, both for the body and the soul. It’s called “Dark Academia.” Consider the recent hit movie and book, “The Secret History,” by Danna Tartt. It follows a talented person without any particular view or direction. The person arrives, looking to make friends and to become special, and through misguided efforts, students end up damaged or killed. Any friendships that result are sinister, and often exploitive.
An early version was Hitchcock’s “Rope,” where two students get excited by a professor expounding the ideas of Nietzsche. They go on to kill one of their fellows who they come to decide isn’t, quite as enlighten as they. Secret History is similar, except that the professor teaches Greek. Another early version was Frankenstein, whose early chapters are of crazed collegians pushing the limits of science in a dark laboratory and similarly dark library settings. For Dr. Frankenstein, the crushing pressure is from inside the student, and not so much from his professors or classmates. University is still a place of refuge, without the pressure of drugs, sex, or fashion.
Harry Potter and friends in dark academic garb. Casual, clean, active, hip-academic.
The evil professor trope of Dark Academia first appears in Harry Potter, I think. The school is both helpful and hurtful, both refuge and enemy. It’s education in a building that tries to trip you, with sadistic professors, plus slave labor, and some murderers or “death eaters.” There are friends too, with the friendship bound by fire-whiskey, or butter-beer, and an intense desire to excel over each other at ones craft, in this case magic. Fashion becomes important in dark academia. Harry Potter’s round glasses, robes, and school neckties, but the alcohol isn’t excessive in HP and the books are pretty chaste where sex is concerned.
Alcohol abuse, fashion, and sex are more central in “The Secret History”. There is a cultish professor, Morrow, and students fashions are described in detail. Most dress in tweeds, and all of them wear round glasses, like Harry Potter’s– in this case with metal rims. All are rich. And as in Hitchcock’s “Rope,” they conspire to murder the least special of their group in the goal of understanding the ancient Greeks. Unlike in Rope, they get away with it.
A yet more recent example is “Kill your darlings” — the main character is played by Daniel Radclift, the same actor who was Harry in the HP movies. It takes place in Columbia University in 1943-46 and portrays the young Alan Ginsberg. As in “Secret History” there is a cultish leader and a murder. Alan enters school not knowing what sort of poetry he’d like to write, or if he’ll write poetry. In the movie, Jack Kerouac, William Burrows and a few others who introduce him to drugs, including heroin, gay sex, wanton destruction, and benzedrine. As in Secret History, there are no bad effects from the drugs, though he tries suicide and one of his group murders another — the least special one as in other dark academia. He gets away with it, as in Secret History, the cult leader is rejected, and the others become special — a happy ending of sorts. Ginsberg writes a great “absurdist” essay and goes on to become a great poet.
Danna Tartt, author models the Dark Academic look. Notice the cigarette.
The mood of dark academia is a mix of repressed anger and innocence that takes place on a campus, but might as easily taken place in bohemian Paris. The movie architecture includes vast dining halls, gothic bell towers and forbidding libraries. The devoted student searches here for hidden light but finds only darkness. Murder follows. Students stare into space like Oscar Wilde with a heartburn, smoking like well-dressed longshoremen on break. See Danna Tartt at left.
The main contributions of Dark Academia is the fashion: Shades of brown, black and gray mostly, casual and active, but clean. The look says, “I’m both sexually active and criminally active; I do drugs think great thoughts, but don’t do homework. I might do murder too, but it’s OK since I plan to submit a killer final project. Morality is for losers, and “Genuine beauty is always quite alarming.” It’s a line from “The secret History,” appears, slightly altered, in Hitchcock’s “Rope.” The tremendous desire to be pure and special; great in a word, and that involves a destruction of the ordinary: an academic aesthetic where murder is the crowning creative act.
In July, eitght years ago, Detroit filed for bankruptcy protection. The US was well into an economic expansion, but the expansion had largely bypassed Detroit. The Detroit area unemployment rate was 9.7%, and the Detroit city rate was 17%, among the highest in the nation. Tax income was not sufficient to pay retirement or current employees. The city was riven by corruption and crime, and attendance in school was dismal, less that 25% in some districts, about 55% as an overall average. Kids no longer saw a value in education. After bankruptcy, things started to improve dramatically.
Detroit area unemployment rate, 2005 to 2021.
The largest cause of the problem, and of the solution, in my opinion, was a high Detroit minimum wage that applied before bankruptcy and that was voided by bankruptcy. It was called a “living wage”. In 2013 it was $16/ hour and applied to any business that dealt with the city and did not offer health insurance (see more on the specifics here).The stated purpose was to insure that all workers could support a family of four in some middle-class standard, by one wage-earner working 40 hours per week. It was a view of Detroit family life and economic need that didn’t match Detroit reality. In practice most of Detroit were not 4 person, one wage-earner households. It meant that most Detroiters could not find jobs, since most companies worked in some way with the city. The only workers who could find jobs were those with special skills or political connections. The alternative was criminal business including drug sales, prostitution and burglary. The unemployment rate was 70% among Detroit’s teenagers.
The high minimum wage bought loyalty for Detroit’s political bosses; they gave out jobs for kickbacks, and some went to jail, including the mayor. Most Detroiters could not find jobs, though, and this especially hurt those looking for their first job: the job that would demonstrate that math and spelling were important; that you had to show up on time, dressed clean, and that you were not to insult the customers. High unemployment meant low tax revenue, made worse by high city employment costs for basic services: janitors, secretaries, and mail room personnel. The city was a mess.
When Detroit went bankrupt, among the first changes was to eliminate the $!6/hour living wage for employees and others doing business with the city. This helped bring the city budget into balance, and it brought in residents, businesses, and developers. By January 2020 Detroit’s unemployment rate had fallen to 6%, and Detroit metro unemployment had fallen to 4.2%, the lowest rates on record. Employment gives a motivation to stay in Detroit and to stay in school: there are jobs to be had for those who could add and spell. I covered these improvements here.
Seattle are unemployment rate 2015 to 2021. Seattle’s unemployment rate is now higher than Detroit’s.
Meanwhile, Seattle voted to raise their minimum wage to $15, with the change law taking effect in stages. The law fully came into effect three months ago, in January, 2021. New York voted for similar changes more recently. It is hard to be sure of the effect of the high minimum wage but already it seems to have hit employment. By the latest data, Seattle’s unemployment rate has risen to 6.9%. That’s higher than in Detroit, a real reversal. While unemployment in New York City has yet to rise much, they have seen a drop in rent rates while Detroit has seen a rise. New York’s are also moving to be more out of balance, something that leads to corruption and bankruptcy. We’ll see how this works out.
22 long rifle shells contain early any propellant.
The most rifle cartridge in the US today is the 22lr a round that first appeared in 1887. It is suitable to small game hunting and while it is less–deadly than larger calibers, data suggests it is effective for personal protection. It is also remarkably low cost. This is because the cartridge in almost entirely empty as shown in the figure at right. It is also incredibly energy efficient, that is to say, it’s incredibly good at transforming heat energy of the powder into mechanical energy in the bullet.
The normal weight of a 22lr is 40 grains, or 2.6 grams; a grain is the weight of a barley grain 1/15.4 gram. Virtually every brand of 22lr will send its bullet at about the speed of sound, 1200 ft/second, with a kinetic energy of about 120 foot pounds, or 162 Joules. This is about twice the energy of a hunting bow, and it will go through a deer. Think of a spike driven by a 120 lb hammer dropped from one foot. That’s the bullet from a typical 22lr.
The explosive combustion heat of several Hodgdon propellants.
The Hodgdon power company is the largest reseller of smokeless powder in the US with products from all major manufacturers, with products selling for an average of $30/lb or .43¢ per grain. The CCI Mini-Mag, shown above, uses 0.8 grains of some powder 0.052 grams, or about 1/3¢ worth, assuming that CCI bought from Hodgdon rather than directly from the manufacturer. You will notice that the energies of the powders hardly varies from type to type, from a low of 3545 J/gram to a high of 4060 J/gram. While I don’t know which powder is used, I will assume CCI uses a high-energy propellant, 4000 J/gram. I now calculate that the heat energy available as 0.052*4000 = 208 Joules. To calculate the efficiency, divide the kinetic energy of the bullet by the 208 Joules. The 40 grain CCI MiniMag bullet has been clocked at 1224 feet per second indicating 130 foot pounds of kinetic energy, or 176 J. Divide by the thermal energy and you find a 85% efficiency: 176J/ 208 J = 85%. That’s far better than your car engine. If the powder were weaker, the efficiency would have to be higher.
The energy content of various 22lr bullets shot from different length barrels.
I will now calculate the pressure of the gas behind a 22lr. I note that the force on the bullet is equal to the pressure times the cross-sectional area of the barrel. Since energy equals force times distance, we can expect that the kinetic energy gained per inch of barrel equals this force times this distance (1 inch). Because of friction this is an under-estimate of the pressure, but based on the high efficiency, 85%, it’s clear that the pressure can be no more than 15% higher than I will calculate. As it happens, the maximum allowable pressure for 22lr cartridges is set by law at 24,000 psi. When I calculate the actual pressure (below) I find it is about half this maximum.
The change in kinetic energy per inch of barrel is calculated as the change in 1/2 mv2, where m is the mass of the bullet and v is the velocity. There is a web-site with bullet velocity information for many brands of ammunition, “ballistics by the inch”. Data is available for many brands of bullet shot from gun barrels that they cut shorter inch by inch; data for several 22lr are shown here. For the 40 grain CCI MiniMag, they find a velocity of 862 ft/second for 2″ barrel, 965 ft/second for a 3″ barrel, 1043 ft/second for a 4″ barrel, etc. The cross-section area of the barrel is 0.0038 square inches.
Every 22 cartridge has space to spare.
Based on change in kinetic energy, the average pressure in the first two inches of barrel must be 10,845 psi, 5,485 psi in the next inch, and 4,565 psi in the next inch, etc. If I add a 15% correction for friction, I find that the highest pressure is still only half the maximum pressure allowable. Strain gauge deformation data (here) gives a slightly lower value. It appears to me that, by adding more propellant, one could make a legal, higher-performance version of the 22lr — one with perhaps twice the kinetic energy. Given the 1/3¢ cost of powder relative to the 5 to 20¢ price of ammo, I suspect that making a higher power 22lr would be a success.
Robert Buxbaum, March 18, 2021. About 10% of Michigan hunts dear every year during hunting season. Another 20%, as best I can tell own guns for target shooting or personal protection. Just about every lawyer I know carries a gun. They’re afraid people don’t like them. I’m afraid they’re right.
In the last presidential election, the largest billionaires in the US were vocal Democrats, and two billionaires, Yang and Bloomberg were candidates. Bloomberg had been an anticrime Republican when he ran for mayor but in 2020 he spent $!B of his own money on anti Republican ads, and paid the debts of thousands of Florida felons who he thought would vote his way. It’s a strange new world.
Other vocal Democrats include: Jeff Bezios, majority owner of Amazon and The Washington Post, Mark Zuckerberg, Facebook, Bill Gates, founder and largest owner of Microsoft (just today blasting the Republicans over global warming — Is that logical — is cold better?), and Warren Buffett who likes to note that he pays a lower tax rate than his secretary does (IMHO that’s because he games the tax system and pays no social security tax). Meanwhile union workers and white middle class folks were mostly Republicans in 2020.
Union leadership are still Democrats, but the last few elections saw union workers voting R. These were called “The basket of deplorables, unredeemables” by candidate Clinton. R support among black people is less than 50%, but growing too. it’s quite a lot higher than two decades ago. Many showed up at MAGA rallies, you’ll see plenty in videos at “the insurrection”. The only person shot and killed at the insurrection was a white woman, unarmed, shot in the face by Capital police — no charges filed, but the liberal press, who usually hate such things, was silent. Almost to the man, they sided with the police over the mob.
I notice that the Black Lives Matter rallies are populated with the well off and the well educated. A Princeton lawyer was photographed driving around with a box of Molotov cocktails, and his co-worker, another lawyer tossed a lit fire bomb into a police car. It used to be that Princeton lawyers didn’t do that, at least not in person.
Portrait of a Democrat. From the New Yorker.
It’s not like the platforms have reversed. The Democratic party was always for high taxes, high regulation, and for soft money that they could give away. They still are. In 1900 the call was for “free silver“, now it’s “stimulus money.” It used to be that rich people didn’t like this. They would point of that printing money didn’t add to wealth, but just redistributed it from those who had savings to those who did not. Now they uniformly blast anyone who doubted the wisdom of printing 1.9 trillion in new money ($6000 per person, of which $1400 is given to you), and going on to blast anyone who doesn’t like additional oversight to prevent the systemic racism they see in the less-well-off.
One reason these richest billionaires are no longer Republicans is that they are no longer involved industrial manufacturing in the US. Thus the regulations they favor don’t apply to them. In the olden days, rich people made steel or cars. Regulations were annoying. Rich industrialists had money in US banks. For them inflation was theft. Now rich people own intangible industries that largely operate outside of the country. What money they earn is earned off-shore, tax free. As individuals, they live on US debt, and possess little or no hard cash. Inflation helps them pay off their debt, and high taxes don’t hurt them. Buffett can be down-home and pro environment. He flies private jet to meetings on global warming while investing in overseas petroleum.
Elon Musk seemed like a Republican during the Trump administration, but not so much now. He still makes stuff in America, but has moved to manufacture abroad. In January, he said he was fired up for Biden. He has put a significant chunk of his wealth into bitcoins. Its a protection from the inflation caused by printing money, and it’s a bet that’s paid off handsomely. I expect that we’ll have billionaire Democrats and union Republicans for the foreseeable future.
Robert Buxbaum, March 14, 2021. It’s pie day. Eat a pie at 1:59:27. (Edited Apr. 28, 2021)
Our company books are done on a Mac mini 2014 that was getting slower and slower for reasons that I mis-diagnosed. I thought it was out of space on the hard drive even though the computer said there was plenty. Then my MacBook started misbehaving too, slowing to a crawl with large web-pages (Facebook) and having trouble backing up. I feared a bug of some sort. Then, 3 weeks ago, the MacBook died. It would not boot up. When I turned it on, it showed a file folder with a question mark. It was dead, but now it’s back thanks to the folks at TechBench on Woodward Ave. I lost some data, but not that much.
As it turns out, the problem was not lack of space on the hard drive, but the hard drive itself. The spinning, magnetic disc that stores my data wore out. I should have seen the problem and replaced the hard drive, but I didn’t realize you could, or should. I replaced the hard drive with a solid state memory bigger than the original, and replaced the battery too. The computer is back, faster than before, and went on to replace the hard drive on the Mini too for good measure. That was 3 weeks ago and everything is working fine.
MacBook hard drive, 120 GB. I replaced it with a solid state stick that had three times the memory and was less than half the size.
I could have bought two new computers, and I have decided to replace the 2011 desktop Mac at work, but I’m happy to have revivified these two machines. A new MacBook would have cost about $1200 while fixing this one cost should have cost $250 — $120 for the hard drive cost and $135 for the fellow who replaced it and recovered as much data as possible. Replacing the battery added another $150 with labor. I saved 2/3 the price of a new MacBook, got more hard disc, and my old programs run faster than before. Fixing up the Mini cost me $250 (no battery), and everything works fine. Because the processor is unchanged, I can still use my legacy programs (Word, pagemaker, photoshop, Quickbooks) and my music.
I’d considered trying to do the same with a 2011 Mini, but Miles at the service center said it was not worth it for a 2011 machine. I have an idea to remove the mechanism and turn this into an external, bootable drive, while transferring the data elsewhere. I’ve done this with old drives before.
In retrospect, I should have made more of an effort to backup data as soon as there was any indication that there was a problems. It was getting slower, and I needed to reboot every other day. As the disc drive wore out, data was being read less and less reliably. Data correction ate up cpu time. The fact is that I forgot I had a spinning disc-drive that could wear out. At least I learned something: hard drives wear out and need replacing. When things break, you might as well learn something. Another thing I learned is about Apple; the computers may cost more than PCs but they last. In the case of my lap book, 2014- 2021 so far.
Robert Buxbaum, March 8, 2021. This isn’t that high tech but it seems useful. As a high tech thought. It strikes me that, just as my laptop battery wore out in 7 years, an electric car battery is also likely to wear out in 7 years. Expect that to be a multi-thousand dollar replacement.
I used to follow an Australian science blog, called “I Fucking Love Science.” Elise Andrew and her crew scanned the literature with a keen eye for the interesting. They regularly posted to Facebook and alerted science nerds like me to all sorts of new science bits with minimal commentary, minimal advertisements, and no politics. On average they found 6 or 8 really interesting posts, per week, generally one or two on fundamental physics, one or two on materials, one or two on biology or medicine, one or two astronomy, perhaps a chemistry post. My post about the color of the sky on Mars was ignited by a picture of the Mars sky that I saw on IFL Science — the sky was yellow, and I had just written about why the sky on earth was blue, and not green.
But, as with all quirky things, this one matured. The name changed to “IFL Science” — a change that I suspect was designed to promote sharing. There were more advertisements, and click bait — “this starlet lost a ton of weight,” “you won’t believe what this famous person’s partner looks like now,” etc. And there was politics, vaguely presented as science. Ms Andrew wrote more and more of herself, making herself into a personality whose travels and speaking tours would interest us. And there were non-science, guest bloggers too: People telling you who to vote for and more importantly who to vote against. All for the good of the world, she said, but it was her opinion, and not what I’d gone to IFL for.
The science got less technical, too and more popular. More pretty pictures and misleading headlines. Currently there is no math, no equations, no chemical diagrams. A top story of this week told of a semi-interesting approach for women with constipation — something that “would change everything.” When you click on the story, you find that women put their finger in their vagina and work out the poop that way, something called “splinting.” It’s sort of science, but not the sort that made me love science. Another top story — the top one from today is as follows:
Top story from IFL science today, Feb 28, 2021. Is there really no fuel use? No. The fuel is a battery, and the speed in 4m/s (9mph), and the plane looks nothing like this.
If you follow the links to here, it turns out that the plane (unmanned) looks nothing like this. It uses electric energy from a battery to move ionized air rearward at an efficiency far lower than with a propeller. The forward speed is 4 m/s (9 mph) and the maximum distance covered was 55m, half a Canadian football field. As presented in IFL science, it’s a misleading, non-math clickbait for something that’s interesting engineering — sort of. As for being Star Trek like, no. To move this plane, you need air.
I’m sorry, you can not make quantum mechanics for dummies. No dummy will understand it. You can make a book that’s not quantum mechanics for dummies, or a quantum book not for dummies. Just saying.
In the treatment of the work of the recent Noble laureates, IFL Science didn’t talk about the work so much as the biographies of the people, and their struggles, and that two of the people who won Nobels for their work in biology were women — for an advance related to CRISPERS– but that wasn’t science. I’d prefer to know what the advance was, and how it works. I’d prefer to figure out that these were women from their names or from the pronouns like, “she” or “her”. There was also no information about other two researchers (males, I assume, or perhaps females who had less-interesting biographies?). It was the same with the Physics Nobel except that I already knew there was a black hole at the center of the galaxy, and that those who found it are long dead. Instead the Note Prize was being awarded for a photograph of the black hole. Interesting (sure doesn’t look like a black hole to me). Is there something they learn from the photo. I’ve noted that we are likely within a black hole, and I show why this is using some, not too difficult math.
Having griped along this way, I have to say that that IFL isn’t that bad, it’s just non-mathy, popular, and a little grown up. That’s sad, but it’s not toxic. Grownups make money, and please customers, and that’s how it goes. To quote a wonderful book, The outsiders, “Nothing gold can stay.” In my own blog, I try to be more math-y, and more science-y. My model is Isaac Asimov, a writer who excited me to love science from when I was 8 to when I entered college, nine years later (1972). He would die of AIDS from a transfusion, 20 years after that.
