Exploring Miami: Tips and Must-Visits for a 3-Day Trip | November 25 2025, 20:03

Miami — what to do there? We’re flying out tomorrow for 3 days — Nadya, Lisa, and me. Throw out some suggestions on what’s worth visiting. And if by chance we have mutual friends from Miami, tag them, please, they might recommend something interesting. To be honest, I only have one museum on my “definitely must-visit” list (Perez), and everything else is kind of iffy.

Navigating a Luxury Hotel: A Maze of Misdirections | October 16 2025, 05:55

I currently live in a luxury hotel (as they describe themselves) for $400 a night. It must be said, I barely found a hotel – everything was sold out. It all started with the fact that there was no hot water in the room. They gave me a new room, which also did not have hot water. But in this new room, a plumber came and whacked the faucet, causing it to turn even more, and then the warm water started flowing. Well, good, now I know how to bang it. But I spent almost half an hour searching for this second room, wandering the corridors and following signs that lead nowhere. When I told the receptionist that only ghosts could improve my mood from the lack of hot water and the forced move, the lady at the reception smiled cunningly and said that anything can happen. And after that, I spent half an hour looking for the room.

Imagine, you are given room 446. You exit the elevator. There you see signs

“to the right 438-456”

“to the right 466-476”

“to the right odd rooms”

“to the left 400-432”

“to the left 478”

You follow the corridor and at the very end of it

“to the right 439-487”

“straight 429-437”

“back 427-401”

Ok, I have 446, so to the right. There’s a door

“straight 439-477”

Hm. Ten rooms just lost by turning towards the door. Well, alright, my 446 is somewhere here.

You enter, and it’s not there. There’s 445 and 447.

It turned out that as I walked from the elevator following the arrow “to the right 438-456”, it wasn’t in vain it said “to the right – odd”. But then where are the even ones? Also to the right! Just not mentioned. The even numbers are behind one of the doors marked “to the right – odd”. You have to walk about ten meters and see on the right side of the corridor a blind door of the same style as the wall with a “exit” sign and numbers 438-454. So the even numbers are behind this door, but how would you know? And what if you have 445? Well good, we go through the door. But there’s nothing there.

Absolutely nothing, just stairs to the fifth and third floors. But there’s also an unmarked door. And behind this door, hurray, even numbers.

Whoever navigated this needs to be beaten with whips. The fact that the hotel is 132 years old does not excuse it)

Understanding Jerusalem Syndrome and Its Global Counterparts | October 01 2025, 16:10

Listening to Sapolsky in the background, he mentioned Jerusalem Syndrome. It’s when a deeply religious American Baptist from the southern USA, having saved money and prepared, arrives in the Holy Land and sees that Jerusalem is just another city: traffic jams, smog, noise, pickpockets, McDonald’s—everything like that. And then—an interesting feature—in all cases, the person tears up sheets, takes off their clothes, and suddenly finds themselves on the streets of Jerusalem, dressed as if in a toga, begins to preach on the streets, calling for a simpler life and all that.

A psychiatric team arrives, takes the person to the hospital for a few days, everything becomes clear, they send him back home, and he never encounters this syndrome again.

Each year in Jerusalem, about up to many dozens of cases are recorded. It’s a recognized syndrome, about which scientific articles are published.

Sapolsky says that if hotels in Jerusalem always had, for example, checkered sheets instead of white ones, which seem to “invite” one to don a toga, it would help prevent the crisis.

But amusingly, there’s a twin brother of this disorder, the Paris Syndrome, which for some reason mainly affects the Japanese. Japanese tourists come to Paris because they are attracted by the culture, language, literature, and history of France, as well as the landmarks of Paris. However, once there, they encounter difficulties such as a language barrier (surprise surprise!), differences in mentality, and disappointment from the reality of Paris not meeting their expectations.

There’s also a milder version called the “Florentine Syndrome.” This often happens during a visit to one of the 50 museums in Florence, the cradle of the Renaissance. Suddenly, a visitor is overwhelmed by the depth of feeling the artist has imbued in the artwork. At this point, they acutely perceive all emotions, as if transported into the space of the image. Victims’ reactions vary up to hysteria or attempts to destroy the painting. Despite the syndrome’s relative rarity, guards in Florentine museums are specially trained on how to deal with its victims.

Overall, be careful with syndromes when you’re traveling.

PS. This image was made for me by google. In the second image, a guy in a tie tells a tearful girl 脆培, which seems just a meaningless set of characters, something like fragile culture. But when I asked ChatGPT, it told me it resembles 脱げ (nugu) — undress 🙂 if you ask Google Gemini to redo it, Google gives the same picture, where he’s also shouting 暁は, but at the same time, he has already taken off his shirt. But that’s also unclear what 暁 – it’s dawn. Generally, with Japanese, LLM is bad. I’ll leave the second image in the comments. By the way, there are several differences there, you can play a game to find ten differences. They are amusing

Revisiting Antalya: 25 Years Later and Family Bonds | September 15 2025, 15:56

I’m back from Antalya. I was there last time 25 years ago. This time I met up with my mom (she’s from Russia) and showed her Turkey №2. Turkey №1 was last year (Istanbul). Here are some photos from this trip. All taken on an iPhone (I brought a camera too, but was too lazy to carry it around).

Russian pop music is no longer blasting from every speaker, but Modern Talking and similar genres are everywhere, until midnight. I was lucky to rent a hotel just 9 steps away from a night bar that quiets down at midnight, but no worries, we got used to it quickly and the music is decent. The city has many Russians, not only because it’s easy to get there, but also because Turkey offers citizenship for $400K — a sum many Russians can afford for a “passport”. But there’s really nothing to do there. You can tour all the natural sites within the first year or two, and then it’s just a very boring city. No museums, no cultural activities, except for more Modern Talking from the bars. So, at a minimum, you need not only to go there for the passport but also actively use it to live somewhere else.

My mom did great, handling all those hills and boats, and had a lot of impressions. Actually, she has only been abroad in Riga and twice in Turkey, last year in Istanbul and this year in Antalya. I really hope for her 80th birthday next year we’ll go somewhere else where Russians don’t need a visa.

Exploring Airport Security: How Baggage Scanners Work | September 02 2025, 20:29

The day after tomorrow, I am flying to Amsterdam (and then to Turkey), and I remembered that I had an unanswered question to myself about how baggage scanners work at the airport. Of course, I knew that it was essentially computer tomography, X-rays and all that, but I wanted more details. And below is the response as to why they ask you to take out water, and why sometimes they do not.

It turns out that modern scanners can not only see the shape of objects but also determine what material they are made of. How does a regular scanner work? Dense materials (such as metal) absorb a lot of radiation and appear bright or opaque in images. Less dense materials absorb little radiation and appear dark. Hence laptops, for example, had to be taken out — not because the scanner couldn’t recognize them, but because their dense components (battery, boards) could be used to hide other prohibited items behind them. So, it has long been not just scanners, but computer tomography — in essence, the bag or suitcase is scanned from all sides, then a 3D image is created. It seems like everyone knows this.

But I mentioned that they understand the materials items are made from. How?

It turns out that the scanner uses dual-energy X-ray technology. It scans the object with two beams of rays of different energy levels (high and low). Since materials absorb radiation differently depending on the energy of the ray and their atomic composition, the system analyzes this difference. Based on the absorption ratio of the two beams, the effective atomic number Z — a key characteristic, a kind of “elemental fingerprint” of the substance, is calculated.

The problem is that this “fingerprint” of water (~7.4) and many explosives are almost identical. This is precisely why water was banned. Relying only on this parameter would mean receiving a huge number of false alarms.

Here is where computer tomography (CT) comes into play. The scanner creates an accurate three-dimensional (3D) model of the contents of the bag. From the 3D model, the system obtains the exact volume (V) of each object. Based on data on the absorption of X-rays, its mass (m) is calculated. Then it’s simple: ρ=m/V.

That is, the system does not make a decision based on one parameter. It plots each detected substance on a two-dimensional graph with axes “Z — density.” On this graph, water and explosives, having almost the same atomic number, occupy completely different positions due to different densities.

And that’s precisely why water can sometimes be carried through. Smart machines simply do not mark it as something significant, but still identify it as water. Then procedures follow. If the airport has updated the machines, but not the procedures, they will ask to dispose of the water. But also, not all machines are updated everywhere, and at the same airport, it depends on which line is open at the moment.

The cost of such a scanner is $300-400 thousand.

The scanners for people work differently. They use millimeter waves. They pass through clothing and reflect back from the skin. Water absorbs them significantly, so they penetrate only a couple of millimeters. The system registers the reflected signal and constructs a three-dimensional map of the body surface and objects under the clothing. But it does not show this — instead, it displays a simplified contour of a person and shows on it what ML found unusual. Therefore, by the way, many try to carry various items inside themselves, knowing that such a scanner absolutely cannot see it.
