Найвищою формою інтелектуальної зрілості є здатність усвідомити, що більшість наших непохитних переконань - це лише тимчасові когнітивні конструкції, якими свідомість маскує власний екзистенційний жах перед безмежністю непізнаного.

Kyiv’s Saint Sophia Cathedral was built 100 years before Moscow was founded. Let that sink in.
Moscow’s Bolshoi theatre was built the same year the United States was founded. Let that sink in.
Readers added context they thought people might want to know
Only the Company was founded in 1776.
The first instance of the current theatre was built between 1821 and 1824.

Найстаріше дерево України - дуб Максима Залізняка.
Цьому дубу понад 1100 років.
Він бачив хрещення Русі, Батия, козаків і смартфони. Дуб Максима Залізняка росте в селі Буда на Черкащині, посеред Холодного Яру.
Його обхват - 9 метрів.

Ukrainian mathematician Maryna Viazovska solved a problem that had puzzled mathematicians for over 400 years. Even Johannes Kepler and Isaac Newton couldn’t crack it.
We live in a three-dimensional world, but Maryna solved a puzzle in an eight-dimensional space—something that’s very hard even to imagine.
She was born in Kyiv, studied at Taras Shevchenko University, worked in Bonn and Berlin, and at just 33 became a professor in Lausanne.
So what was the problem? It’s about how to pack identical spheres as tightly as possible in space. This question was first asked by Kepler back in 1611. Over time, scientists found answers for two and three dimensions—but not for eight.
Maryna proved that in eight dimensions, the densest packing is formed by a special mathematical structure called a lattice. What’s even more amazing is that she did it in just 23 pages, while earlier attempts took hundreds.
In 2022, she was awarded the Fields Medal, the most prestigious prize in mathematics. She became only the second woman in history to receive it.
Today, Maryna Viazovska works in Lausanne, supports Ukrainian mathematicians, and brings pride to Ukraine with her achievements.

I ask you to mention under this post the talented young Ukrainian teacher, mathematician and volunteer, winner of the European Mathematical Olympiad among girls, Yulia Zdanovska, who was killed by the Russians as a result of shelling of peaceful civilian homes in Kharkiv.

NASA’s Curiosity rover just captured something truly magical on Mars: rare, iridescent “mother-of-pearl” clouds shimmering high in the alien sky!These aren’t ordinary clouds. While Earth’s clouds are made of water droplets, these Martian beauties are formed from dry ice — frozen carbon dioxide crystals floating at dizzying altitudes where temperatures plunge to unimaginable lows.What makes them absolutely breathtaking is the rainbow-like glow. As the Sun slips below the horizon, the last rays of sunlight catch the tiny, perfectly uniform ice crystals, scattering light into vivid, shifting colors of pink, blue, and green. The result? A spectacular iridescent display that looks more like cosmic art than weather.These clouds only appear briefly during specific seasons on Mars, glowing brightest right after sunset when the sky turns deep purple and the crystals act like floating prisms.It’s a stunning reminder of how strange and beautiful the Red Planet can be — a world where clouds are made of frozen CO₂ and sunsets paint the heavens with otherworldly rainbows.What other rare space weather phenomena or breathtaking celestial events would you love to see captured by our rovers on Mars?

These iridescent "mother-of-pearl" clouds on Mars are real, but this image was captured by NASA's Curiosity rover on Jan. 27, 2023, not recently.

Karoline Leavitt: "we had a very stupid and incompetent leader in this White House for four years who gave away many of our best weapons for nothing, for free, to another country very far away by the name of Ukraine."
Honestly, the sheer heartlessness, ruthlessness, and cruelty of saying that while we are still under attack, trying to survive. While entire families are being killed in russian bombings due to a lack of air defense missiles, and when we barely survived last winter’s humanitarian catastrophe caused by russian strikes on our infrastructure. I don’t know... I’m just stunned.

Honestly, I’m genuinely stunned by the sheer amorality and the complete absence of even a drop of conscience.
And the most astonishing part is the sheer pointlessness of this demonstrative repetitive disgrace. The total pointlessness of this absurd lies and smearing of Ukraine -- for absolutely nothing.

Якщо це не дискримінація, то що?
If this isn’t discrimination, then what is?
Вже завтра стартують змагання зі скелетону на Олімпійських іграх 2026. Але замість підготовки до стартів ми вимушені боротися за право виступати в «Шоломі Пам’яті».
Повертаємося до теми подвійних стандартів МОК. Аналогічна ситуація склалася з ізраїльським скелетоністом: на церемонії відкриття він вийшов у кіппі (про що напередодні заявив у своїх соціальних мережах), на якій були вказані імена 11 ізраїльських спортсменів та тренерів, убитих терористами на Олімпіаді в Мюнхені 1972 року. Тобто спортсмен буквально помістив пам’ять про загиблих на свою голову, щоб ушанувати їх.
Я відверто не розумію, чим принципово відрізняються ці два випадки. Правила МОК є однаковими на церемоніях відкриття, нагородженнях та на місцях проведення змагань.
Чому до українців таке ставлення?
«Шолом Пам’яті» має бути дозволеним на змаганнях.

Tomorrow the skeleton competitions at the 2026 Olympic Games begin. But instead of preparing for the starts, we are forced to fight for the right to compete in the “Memory Helmet”.
Let’s return to the topic of the IOC’s double standards. A similar situation occurred with the Israeli skeleton athlete: at the opening ceremony, he appeared wearing a kippah (which he had announced in advance on his social media), on which were written the names of the 11 Israeli athletes and coaches killed by terrorists at the 1972 Munich Olympics. In other words, the athlete literally placed the memory of the fallen on his head to honor them.
I honestly don’t understand how these two cases are fundamentally different. The IOC rules are the same for opening ceremonies, medal presentations, and competition venues.
Why such treatment towards Ukrainians?
The “Memory Helmet” must be allowed in competitions.

4 years ago at the 2022 Olympic Games.
Unfortunately, over these years this call for peace has only become even more relevant.
Also over these 4 years, the IOC has changed dramatically. Back then, in that action, they saw a call for peace and did not apply any sanctions against me.
Now, at the Olympics, we have already seen a large number of Russian flags in the stands, on the helmet of one of the athletes - and for the IOC, this is not a violation.
Yet a violation was found in the “helmet of memory”, which pays tribute to members of the Ukrainian sports family who have been killed since the last Olympic Games were held.
The truth is on our side.
I hope for a fair final decision from the IOC.
