It’s funny to stare at a sentence in a book that says when you fly to the other end of the USA, you become younger than everyone else by a quintillionth of a second — at the moment when you’re sitting on the plane flying to the other end of the USA.
Hello, Seattle!
Took with me on the plane to read
I wonder why smart systems, cameras, driver assistance systems in driving are not used on commercial transport such as trucks and buses? It’s one thing to integrate such statuses into a $35K car, and another into a truck or bus, whose prices start at least at $100-150K, and in some cases more. Buses are often purchased by organizations for whom an extra $5-10K on a price of $100-150 may not make much of a “difference” in deciding what to buy. Although of course understanding that there, with a tender for the minimum price, every thousand could be decisive. On the other hand, insurance might be lower, and it can be nicely sold to people (passengers). Also, it seems that truck drivers falling asleep are simply more dangerous and costly than personal car drivers falling asleep.
Indeed
Here you have the real “fast-walking boots” or, as they were called in Europe, “seven-league boots,” France/Germany, 19th century. Remember, Mr. Ogre in “Sleeping Boy” wore them. You wouldn’t be mistaken to say that they were difficult not only to run in, but even to walk in. Why are they called “seven-league” then?
This is interesting. Actually, their original name in French is „bottes de sept lieues (seven-league boots), and in German — Siebenmeilenstiefel (seven-league boots), from which the name came into Russian.
Regular postal communication in France started in the 15th century when postal stations with horses for exchange were built. The distance between the stations initially was 7 leagues/lieues (about 30-35 km).
Transportations were performed by coaches that had from 4 to 6 horses. The coachman managed them, and on the lead horse sat the ‘fourrier,’ who set the pace of the journey. The work of the fourrier was more dangerous, as in the event of an accident he had more chances of being injured, falling under the carriage wheels or being crushed by a falling horse compared to the coachdriver.
Therefore, fourriers were entitled to special tall and sturdy boots, which, according to some data, were attached to the saddle (but this is not certain). When mounting, he would wear these boots. That is, in these seven-league boots they didn’t even walk, but sat.
These boots were sewn from several layers of treated leather, with wooden soles and iron inserts. In such boots, it was difficult to fall from the saddle, even if one fell asleep, and if one fell sideways, they could withstand the weight of a horse, protecting the rider from serious injuries.
Naturally, such large and heavy boots, which were often dried by the fire, raised questions among children, and the fourriers, smoking their pipes and smiling, would tell them about the magical seven-league boots that one could put on and leap seven leagues in a blink. Undoubtedly, one of these children must have been Charles Perrault 😉
You know, 99.9% of Americans have never tried blackcurrant. It was legally banned here in 1911 because blackcurrants carried a disease that killed pine trees. And along with it, gooseberries and Kinder Surprise were banned too. It even got to the point where in the USA, purple Skittles are grape-flavored, while in Europe, they taste of blackcurrant.
But today I am thinking about something else. I wondered why in Russian blackcurrant is called ‘smorodina,’ and in English, it’s called ‘currant.’ It turns out that ‘smorodina’ is related to the word ‘smrad,’ which meant a strong smell because, according to our ancestors, it smelled bad. ‘Smrad’ used to mean any strong smell. I don’t know how unpleasant it was for them, but this differentiated it from gooseberries, both of which grew along rivers, hence in Ukrainian and Polish, it’s also called ‘porzeczka’ and ‘porichka,’ especially the red and white varieties. To me, gooseberries even smell stronger.
The English name is also interesting. The English ‘currant’ stems from the Middle English ‘rayson of Corantes’ (‘grapes from Corinth’), where ‘Corantes’ is a distortion of the Greek city Corinth. In the Middle Ages, small dried grapes were actively imported into England from Greece (specifically the region around Corinth) and these dried berries were called ‘raisins of Corinth,’ which later shortened to ‘currant.’ Originally, ‘currant’ referred specifically to raisins, dried grapes (essentially, small raisins). And it still means that in some places.
But then a shift in meaning occurred. Later, when shrubs of the Ribes genus (currant bushes), specifically Ribes rubrum (red currant) and Ribes nigrum (black currant), began to be cultivated in Northern Europe, they were given the same name, since their berries were also small and dark like the Greek raisins. Thus, the word ‘currant’ came to be used to denote both currants and gooseberries 🙂 but later on they were differentiated. Yes, gooseberries and currants turned out to be related both biologically and etymologically.
And do you remember the fairy tale about the good heroes and warriors Dobrynya Nikitich, who fought the three-headed Chudo-Yudo on the Kalinov Bridge spanning the River Smorodina? Well, that river, Smorodina, marked the boundary between the world of the living (Yav) and the world of the dead (Nav).
We finished the third season. They did a great job, but I really want to highlight two things — the script and the design. Probably one of the most stylish shows, and they managed to film the third season in such a way that it is simultaneously predictable in some aspects and full of completely unexpected twists in others.
Have you watched it? What did you think?
Well, it hasn’t even been two months since I bought the Model Y, and I’ve already replaced the windshield. An unfortunate stone flew from under the wheels of some truck. The result — a crack that grew every few days of waiting for the repair.
Overall, it was known from the start that Tesla’s service is not as good as their cars, but so far my experience with the service has been most wonderful — except for the fact that I ended up paying $1000 out of the blue (not their fault, of course).
As soon as you get a crack, you create a claim through the app and set up a repair. The nearest available date was in two weeks from that day. The estimate came immediately through the app: $1,140. This included a new windshield ($1000 with a 50% discount) and labor — about $600. The insurance will only pay me $140, because I pay the first thousand as per the insurance terms.
The repair works like this: you arrive at the appointed time, and leave the car. The reception already knows you have arrived and why you are there. The initial estimate for completion in the app was 6 PM — that’s 10.5 hours after the appointed time. I brought two laptops, headphones, a charger, and hadn’t finished my coffee when I received a message that everything was done. It took 40 minutes.
So, the experience with their service was excellent, although of course it would have been better if there had been no need for it at all.
Very good news about the old from Raevsky
I wonder why we still don’t see autonomous drones that could lead an “eternal” life: landing on roofs, deploying solar panels, charging from the sun, and taking off once a day for whatever their mission might be? When you consider the energy aspects, it seems like a feasible scheme. For instance, a heavy drone weighing about 8 kg could carry foldable solar panels with an area of 1.5 m² and a battery with a capacity of 2 kWh. In one sunny day, such panels could collect about 1.2 kWh of energy — enough for it to fly for 20 minutes at a speed of 40–50 km/h, take photos, and transmit them via the mobile network. And there would still be a reserve of energy for several cloudy days.
Even a light drone weighing 2 kg with small panels (0.5 m²) could rise into the air for 10–15 minutes every day if it managed to find good weather and a sunny roof. The power required for hovering for such devices is about 150–200 W, and solar panels with 20% efficiency at mid-latitudes can produce up to 350–400 Wh per day. The balance comfortably adds up, especially if not chasing speed and if there’s no rush on the roof.
Such a “solar nomad” could live for weeks and months, flying from roof to roof and charging in anticipation of missions. At first glance, the technology of batteries and panels already allows this to be done. Or am I missing something?
