Space, time: The continual question
If time moves differently on the peaks of mountains than the shores of the ocean, you can imagine that things get even more bizarre the farther away from Earth you travel.

To add more complication: Time also passes slower the faster a person or spacecraft is moving, according to Einstein’s theory of special relativity.

Astronauts on the International Space Station, for example, are lucky, said Dr. Bijunath Patla, a theoretical physicist with the US National Institute of Standards and Technology, in a phone interview. Though the space station orbits about 200 miles (322 kilometers) above Earth’s surface, it also travels at high speeds — looping the planet 16 times per day — so the effects of relativity somewhat cancel each other out, Patla said. For that reason, astronauts on the orbiting laboratory can easily use Earth time to stay on schedule.

For other missions — it’s not so simple.

Fortunately, scientists already have decades of experience contending with the complexities.

Spacecraft, for example, are equipped with their own clocks called oscillators, Gramling said.

“They maintain their own time,” Gramling said. “And most of our operations for spacecraft — even spacecraft that are all the way out at Pluto, or the Kuiper Belt, like New Horizons — (rely on) ground stations that are back on Earth. So everything they’re doing has to correlate with UTC.”
But those spacecraft also rely on their own kept time, Gramling said. Vehicles exploring deep into the solar system, for example, have to know — based on their own time scale — when they are approaching a planet in case the spacecraft needs to use that planetary body for navigational purposes, she added.

For 50 years, scientists have also been able to observe atomic clocks that are tucked aboard GPS satellites, which orbit Earth about 12,550 miles (20,200 kilometers) away — or about one-nineteenth the distance between our planet and the moon.

Studying those clocks has given scientists a great starting point to begin extrapolating further as they set out to establish a new time scale for the moon, Patla said.

“We can easily compare (GPS) clocks to clocks on the ground,” Patla said, adding that scientists have found a way to gently slow GPS clocks down, making them tick more in-line with Earth-bound clocks. “Obviously, it’s not as easy as it sounds, but it’s easier than making a mess.”

Tbilisi, Georgia — Jailed journalist Mzia Amaghlobeli gets weaker every day as her hunger strike has reached three weeks in Rustavi, a town near the Georgian capital of Tbilisi, her lawyer says. Now the 49-year-old is having difficulty walking the short distance from her cell to the room where they usually meet, and human rights officials, colleagues and family fear for her life.

Amaghlobeli was arrested Jan. 12 during an anti-government protest in the coastal city of Batumi, one of over 40 people in custody on criminal charges from a series of demonstrations that have hit the South Caucasus nation of 3.7 million in recent months.

The political turmoil follows a parliamentary election that was won by the ruling Georgian Dream party, although its opponents allege the vote was rigged.

Protests highlight battle over Georgia's future. Here's why it matters.
Its outcome pushed Georgia further into Russia's orbit of influence. Georgia aspired to join the European Union, but the party suspended accession talks with the bloc after the election.

As it sought to cement its grip on power, Georgian Dream has cracked down on freedom of assembly and expression in what the opposition says is similar to President Vladimir Putin's actions in neighboring Russia, its former imperial ruler.

‘A whole different mindset’
Accurate clockwork is one matter. But how future astronauts living and working on the lunar surface will experience time is a different question entirely.

On Earth, our sense of one day is governed by the fact that the planet completes one rotation every 24 hours, giving most locations a consistent cycle of daylight and darkened nights. On the moon, however, the equator receives roughly 14 days of sunlight followed by 14 days of darkness.

“It’s just a very, very different concept” on the moon, Betts said. “And (NASA is) talking about landing astronauts in the very interesting south polar region (of the moon), where you have permanently lit and permanently shadowed areas. So, that’s a whole other set of confusion.”

“It’ll be challenging” for those astronauts, Betts added. “It’s so different than Earth, and it’s just a whole different mindset.”

That will be true no matter what time is displayed on the astronauts’ watches.

Still, precision timekeeping matters — not just for the sake of scientifically understanding the passage of time on the moon but also for setting up all the infrastructure necessary to carry out missions.

The beauty of creating a time scale from scratch, Gramling said, is that scientists can take everything they have learned about timekeeping on Earth and apply it to a new system on the moon.

And if scientists can get it right on the moon, she added, they can get it right later down the road if NASA fulfills its goal of sending astronauts deeper into the solar system.

“We are very much looking at executing this on the moon, learning what we can learn,” Gramling said, “so that we are prepared to do the same thing on Mars or other future bodies.”

Lunar clockwork
What scientists know for certain is that they need to get precision timekeeping instruments to the moon.
[url=https://kra30c.cc]кракен даркнет[/url]
Exactly who pays for lunar clocks, which type of clocks will go, and where they’ll be positioned are all questions that remain up in the air, Gramling said.

“We have to work all of this out,” she said. “I don’t think we know yet. I think it will be an amalgamation of several different things.”

Atomic clocks, Gramling noted, are great for long-term stability, and crystal oscillators have an advantage for short-term stability.
“You never trust one clock,” Gramling added. “And you never trust two clocks.”

Clocks of various types could be placed inside satellites that orbit the moon or perhaps at the precise locations on the lunar surface that astronauts will one day visit.

As for price, an atomic clock worthy of space travel could cost around a few million dollars, according Gramling, with crystal oscillators coming in substantially cheaper.

But, Patla said, you get what you pay for.

“The very cheap oscillators may be off by milliseconds or even 10s of milliseconds,” he added. “And that is important because for navigation purposes — we need to have the clocks synchronized to 10s of nanoseconds.”

A network of clocks on the moon could work in concert to inform the new lunar time scale, just as atomic clocks do for UTC on Earth.

(There will not, Gramling added, be different time zones on the moon. “There have been conversations about creating different zones, with the answer: ‘No,’” she said. “But that could change in the future.”)

Остеопатическое лечение: принципы, методы и показания
Остеопатия — это направление медицины, основанное на целостном подходе к организму. Она рассматривает тело как единую систему, где дисфункция одного элемента влияет на другие. Остеопатическое лечение направлено на восстановление баланса, мобилизацию внутренних ресурсов и устранение причин заболеваний, а не только их симптомов.
обратитесь в центр Ода [url=https://osteo-oda.ru/child.html]речевые расстройства[/url]
1. Основные принципы остеопатии
Остеопатия базируется на трех ключевых принципах:
1. Единство тела – все органы, мышцы, кости и нервы взаимосвязаны.
2. Структура и функция – нарушение анатомии (смещение, напряжение) ведет к дисфункции органа.
3. Саморегуляция – организм способен самовосстанавливаться при правильном воздействии.

2. Методы остеопатического лечения
Остеопатия включает несколько направлений:
Структуральная остеопатия
• Работа с опорно-двигательным аппаратом (суставы, позвоночник, мышцы).
• Применяется при остеохондрозе, сколиозе, болях в спине, последствиях травм.
Висцеральная остеопатия
• Воздействие на внутренние органы (печень, почки, желудок).
• Помогает при нарушениях пищеварения, спайках, застойных явлениях.
Краниосакральная терапия
• Коррекция ритмов черепа и крестца.
• Используется при мигренях, бессоннице, неврозах, последствиях родовых травм.

3. Показания к остеопатическому лечению
• Лечение заболеваний позвоночника (грыжи, протрузии, радикулит).
• Лечение головных болей и мигрени.
• Лечение нарушения осанки (сколиоз, кифоз).
• Лечение болезней суставов (артроз, артрит).
• Лечение проблем ЖКТ (запоры, дискинезия желчевыводящих путей).
• Лечение последствий травм (переломы, растяжения, ДТП).
• Лечение приинекологических нарушениях (болезненные месячные, спайки).
• Лечение при неврологических расстройствах (бессонница, ВСД). Лечение синдром хронической усталости (выгорание, стрессы).

4. Как проходит сеанс остеопатии?
1. Диагностика – врач остеопат руками определяет зоны напряжения и дисфункции.
2. Коррекция – мягкие мануальные техники (без резких движений!).
3. Рекомендации – советы по образу жизни, упражнениям.
Длительность: 40–60 минут.
Курс: обычно 3–8 сеансов с интервалом в 1–2 недели.

5. Противопоказания
? Острые инфекции (температура, воспаление).
? Остеопороз в тяжелой форме.
? Опухоли, тромбозы.
? Психические расстройства.

6. Остеопатия для детей
Особенно эффективна при:
• Лечение родовых травмах.
• Кривошее.
• Лечение гиперактивности (СДВГ).
• Лечение при задержке развития.

7. Отличие остеопатии от мануальной терапии
Критерий Остеопатия Мануальная терапия
Подход Целостный, мягкий Локальный, жесткий
Техники Безболезненные Может быть дискомфорт
Цель Устранение причины Снятие симптомов

8. Вывод
Остеопатия – безопасный и эффективный метод лечения, который помогает не только при болях в спине, но и при многих хронических заболеваниях. Главное – выбрать квалифицированного специалиста с медицинским образованием.

Kate Winslet had a surprising ‘Titanic’ reunion while producing her latest film ‘Lee’
[url=https://kraken2trfqodidvlh4a37cpzfrhdlfldhve5nf7njhumwr7instad.vip]kraken5af44k24fwzohe6fvqfgxfsee4lgydb3ayzkfhlzqhuwlo33ad.onion[/url]

Kate Winslet is sharing an anecdote about a “wonderful” encounter she recently had with someone from her star-making blockbuster film “Titanic.”

The Oscar winner was a guest on “The Graham Norton Show” this week, where she discussed her new film “Lee,” in which she plays the fashion model-turned-war photographer Lee Miller from the World War II era.

kraken5af44k24fwzohe6fvqfgxfsee4lgydb3ayzkfhlzqhuwlo33ad.onion
Winslet recounted that while she had previously executive produced a number of her projects, “Lee” was the first movie where she served as a full-on producer. That required her involvement from “beginning to end,” including when the film was scored in post-production.

She explained to Norton that when she attended the recording of the film’s score in London, while looking at the 120-piece orchestra, she saw someone who looked mighty familiar to her.

“I’m looking at this violinist and I thought, ‘I know that face!’” she said.

At one point, other musicians in the orchestra pointed to him while mouthing, “It’s him!” to her, and it continued to nag at Winslet, prompting her to wonder, “Am I related to this person? Who is this person?”

Finally, at the end of the day, the “Reader” star went in to where the orchestra was to meet the mystery violinist, and she was delighted to realize he was one of the violinists who played on the ill-fated Titanic ocean liner as it sank in James Cameron’s classic 1997 film.
“It was that guy!” Winslet exclaimed this week, later adding, “it was just wonderful” to see him again.

“We had so many moments like that in the film, where people I’ve either worked with before, or really known for a long time, kind of grown up in the industry with, they just showed up for me, and it was incredible.”

“Lee” released in theaters in late September, and is available to rent or buy on AppleTV+ or Amazon Prime.
