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.”

‘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.”

Цифровой микроскоп это современное устройство, позволяющее визуализировать объекты под высоким увеличением, обеспечивая дополнительную функциональность из-за цифровым технологиям. Эти микроскопы употребляются в различных областях, включая биологию, медицину, материаловедение и образование. Главное достоинство цифровых микроскопов заключается в возможности захвата изображений и видео, а также в простоте анализа и хранения данных.

Люминесцентный микроскоп

Люминесцентный микроскоп это https://thietbicongnghiepmiennam.com/san-pham/dau-can-shl-roll-sc-0001/#comment-124643 спец вид микроскопа, который использует свойства флуоресценции для визуализации образцов. Такой микроскоп оборудован источником ультрафиолетового света, который возбуждает молекулы флуоресцентных красителей в образце. В итоге они начинают сиять, что дает возможность изучить клеточные структуры и процессы на молекулярном уровне.

Применение:

- Биомедицина: используется для изучения клеток и тканей, маркированных флуоресцентными красителями.
- Научные исследования: помогает в детальном изучении http://kaece.or.kr/bbs/board.php?bo_table=53&wr_id=43722 биологических процессов, таких как реакция клеток на внешние стимулы.

Флуоресцентный микроскоп

Флуоресцентный микроскоп является неотъемлемой долею исследования живых клеток и тканей благодаря https://hmtl.tl.itb.ac.id/2022/04/07/the-ticking-bomb-of-climate-change/?unapproved=155275&moderation-hash=c147a385b52cd952339fcd9030addb38#comment-155275 своей возможности обнаруживать флуоресцентные метки. В небольшом отличии от люминесцентного микроскопа, который довольно частенько рассматривается как его подвид, флуоресцентный микроскоп работает с несколькими флуоресцентными красителями одновременно, что дает возможность визуализировать разные составляющие в образце.

Особенности:

- Возможность многоканального анализа: исследование нескольких маркированных объектов сразу.
- Применение в молекулярной биологии: дозволяет отслеживать взаимодействия меж молекулами в живых клетках.

Медицинский микроскоп

Мед микроскоп это особый вид микроскопа, который предназначен для анализа образчиков в клинических и патологоанатомических лабораториях. Такие микроскопы имеют высокую разрешающую способность и могут использовать различные способы освещения, включая ясное поле, черное поле и флуоресценцию, что делает их неподменными при диагностике.

Применение:

- Гистология: анализ тканей и клеточных структур для диагностики заболеваний.
- Цитология: исследование клеток, чтоб выявить аномалии либо патологические изменения.
- Бактериология: изучение образцов на предмет наличия патогенных микроорганизмов.

Заключение

Цифровые, люминесцентные, флуоресцентные и медицинские микроскопы играют важную роль в современном научном и медицинском исследовании. Эти устройства включая позволяют рассматривать и визуализировать микроскопичные структуры, да и обеспечивают возможность более глубочайшего понимания био процессов. Выбор подходящего типа микроскопа может зависеть от целей исследования и специфики образчика, что делает их необходимыми инструментами в различных областях науки и медицины.

Lunar clockwork
What scientists know for certain is that they need to get precision timekeeping instruments to the moon.
kraken вход
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.”
https://kra30c.cc

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.”)
