Today I learned from the museum that in field conditions, soldiers used the steel body of the M1 helmet as makeshift dishware: they boiled water, shaved, washed clothes, etc. The helmet consisted of two parts: a steel outer body and a separate inner plastic or fiber liner (liner), which could be worn separately (for instance, for ceremonies). By the way, it was in military service from the beginning of WWII until the 1980s.
We stopped by a small farm store on the way. Open 24/7. You grab what you need, money into an envelope, envelope into the slot. Or digitally via QR codes. Bought some soft goat cheese, goat’s milk ice cream, and cucumbers (grown next to the goats). Farm products here are about twice as expensive as store-bought, but they are limited edition, and sometimes unique in the area.
Nothing unusual, just a penny-farthing in the parking lot in front of the bike trail. Had a chat with the owner. Very interesting
Copper telephone trunk cable. Here are 3,200 (!) color-coded wires each 0.4 mm in diameter. Such cables are usually made up of twisted pairs (each pair consists of two wires), and 3,200 wires mean 1,600 pairs. The entire cable has a diameter of 9 cm and is produced in 250-meter segments. These segments need to be joined together, and then the ends connected to equipment. So, each of the 3,200 cores is carefully stripped and connected to the corresponding wire of the next segment. Probably a very entertaining activity.
I’ve been thinking, it’s been a while since there was an exciting video from Boston Dynamics. Remember, each one used to create quite a stir online. I checked their channel. And it looks good. Hundreds of millions in investments from the Pentagon/US Department of Defense suggest that it won’t stop at drones.
Yesterday late, around 10-11pm, I was returning from Washington by metro. At the exit of Ashburn station, a relatively well-dressed guy approaches me and asks how to get to Route 7 from the station by bike. I start to answer, then he asks me if I happen to speak Russian. My accent gave me away (damn, how did he know exactly?)
I open the map on my phone, start explaining it to him, go right here, then left, then right, a 45-minute ride. It’s night outside. The dude’s on a bike. He doesn’t have a phone — something is broken or dead. But the most interesting thing, he doesn’t know the address where he needs to go. And Route 7, by the way, is 497 km long, but he obviously meant a segment about 30 km near the metro, but it was still not clear where he needed to go in that section.
In the conversation, it turned out that he knows how to get to the place where he stopped (friends?), from the local Russian-speaking Protestant church, called New Life. I feel I’m explaining to him, he’s overall ready to go alone in the dark without navigation, but from his feedback, I understand he didn’t get it, and at the first turn, he’d go wrong. And at that time, there was absolutely no one on the streets, it’s a neighborhood and data center area (the largest in the world, by the way), very safe, but absolutely deserted. I tell him — my car is parked at the metro, let me give you a lift if that’s the case, it’s no trouble for me.
His name is Edik. He wrecked his car a week ago because he liked to drive “with a breeze”. He regrets it because now he doesn’t understand what to buy a new one with. Lives in Baltimore, came to our area because there’s some Mongolian holiday tomorrow. What? I ask, what the hell is a Mongolian holiday. Turns out he’s from Mongolia, lived there before moving to the USA. Russian family, school at the Russian embassy. Speaks Russian without an accent, and fluent in Mongolian. Illegal. Apparently, he came to the USA on a tourist visa and stayed. Works in a store somewhere near Baltimore. Deep in debt. Apparently, a few adventures weren’t enough and he went to Virginia by bike mixed with metro and buses.
I hope he made it home from the church.
While walking with Yuka, suddenly the owner falls on his knees and digs around in the grass for a while. That’s when I found a firefly and wanted to capture it lighting up. The firefly Photinus pyralis is quite common here, but I never got around to studying it closely.
Interestingly, the females of another genus of fireflies, Photuris, use the flashes of Photinus males to locate and eat them. It has been discovered that the females acquire special steroids called lucibufagins from their prey, which repel spiders.
(While figuring this out, I learned something new. Luciferase, an enzyme responsible for the glow, is extracted from these fireflies. It’s named after the word Lucifer, Latin for “light-bearer.” Interestingly, Greece also had its Lucifer, “light-bearer,” known as the god Phosphorus. Incidentally, the element Phosphorus was discovered by alchemist Hennig Brand through the evaporation of urine. He named the discovered element phosphorus mirabilis, from Latin meaning “miraculous light-bearer.” This just shows how many things in the world are connected.)
Tomorrow is July 4th – Independence Day.
I’m currently reading about it. It turns out that the authentic Declaration of Independence is lost to history, and the document labeled “Original Declaration of Independence” in the National Archives is actually a copy.
By the way, about 80% of the text of the declaration lists why the king is bad. Literally. He doesn’t do this, he doesn’t do that, he forgot about us here, he didn’t remember there. It’s just a straight protest of no kings. The last paragraph of the long text essentially says, in sum, forget him. We want to handle it ourselves.
Jefferson prepared the draft of the Declaration of Independence with all the usual revisions—crossed out words, inserts in the gaps, etc., all written in his poor handwriting. This document exists and is very interesting.
The rest of the committee approved the text, and Jefferson then created a fair copy (still in his bad handwriting and just the size of a regular sheet), which was presented to Congress, voted on, adopted, and received its first signatures. This “fair copy” was the real original Declaration of Independence—and it is precisely this one that is lost.
Later, Congress decided that a version suitable for publication was needed—bigger and, of course, not written in Jefferson’s terrible handwriting. For this, they hired a professional copyist. When he made his copy, Congress held a re-signing. This version by the copyist has the label “Original Declaration of Independence” on the back and is the one currently displayed in the National Archives. It was “original” only in the sense that it served as the master copy for printing.
So what happened to Jefferson’s “fair copy,” the genuine original Declaration of Independence? No one knows. It might still be somewhere in the archives, lost among other documents. Or perhaps someone took it home and preserved it, or maybe it was destroyed by time and circumstances, such as when the British burned Washington.
In 1989, a man named Michael Sparks bought an old painting at a flea market in Pennsylvania for $2.48. When he removed the frame, he discovered a rolled-up piece of paper behind it. This turned out to be one of the rare “Dunlap Broadsides”—the first 200 printed copies of the U.S. Declaration of Independence, printed on the night of July 4 to 5, 1776, by John Dunlap.
This find was in excellent condition and was sold at a Sotheby’s auction in 1991 for 2.42 million dollars (and later resold for even more). This isn’t Bitcoin!
A bit about the dates. On July 2, Congress voted for independence. Not the 4th. On July 4, it was formally ratified by Congress, they spent two days making minor formal amendments, having already decided on the substance. No signatures yet. The date on the document, of course, is the 4th. Copies were printed and sent out the next day. Eventually, the ones sent out were signed by the delegates only on August 2.
Three of the first five American presidents died on this day. Jefferson, Adams, Monroe. Jefferson was in fact the father of this declaration, with Adams, they found the time. So maybe July 2nd would be a more appropriate day to celebrate.
Yes, also—technically—America did not gain independence in 1776. It happened only after the signing of the Treaty of Paris (September 3, 1783), when Britain said: “Alright,” and recognized America as a separate state.
If the War of Independence hadn’t turned in favor of America, Washington (like most of the founding fathers) would likely have been executed for treason. But since it turned out otherwise, they picked that day.
Before painting it with oil, I study the perspective in a specific photo from IKEA. And here it is very noticeable why photo references should be used cautiously for drawing: camera lenses introduce significant distortions (this was already known and visible, the question is which ones and how to fix them when transferring onto a canvas). Look at this, the ellipses in pink and green were added by me, as well as the vanishing point and lines to it. Everything on the edge is distorted. Pay attention, for instance, to the neck of the bottle on the left.
A good exercise to prepare everything in advance on the canvas.
I returned from Mexico — visited Xplor Park by Xcaret in Riviera Maya. The park is already 18 years old, but damn, it’s an engineering feat, not just a park. As an engineer, I was walking around with my mouth open.
The park is the size of Moscow’s “Neskuchny Garden”. A significant part consists of kilometers of natural karst caves, formed millions of years ago at the site of the Chicxulub impact crater (the very one that ended the era of dinosaurs). Above the caves are dense jungles. High above the jungles — kilometers of zip lines. The water in the caves is from a natural underground stream, which is filtered through limestone plus some technical structures. Bats fly around, but obviously, they are not wild and are working for food. No wildlife (other than tourists and bats) is present, so it’s pretty well isolated from the outside world. In these kilometer-long caves, completely covered with stalactites and stalagmites, we swam, rafted, and even drove through in amphibious vehicles with gasoline engines (meaning, the ventilation is well-thought-out).
In front of us, three Mexican women failed to control their vehicle and crashed into a tree. Literally — the front wheels of the buggy were above my head. We picked them up walking along the track, sat them back, and about 5-10 minutes down the road, park workers took them away. The girls have something to remember.
The ticket includes a very, very good buffet restaurant. But pictures are essentially a must-buy — a very thoughtful system designed to extract about 100 dollars from a visiting family. Helmets are embedded with a chip, the system classifies the pics on the fly, and at the exit, you can see all your photos and buy them right there. And on the way back to the hotel, you can post on Facebook or Instagram.
Well, we’re back home now, back to work from Monday.
