BF's Believe It or Not - Post an Amazing Fact Here

Sort of a BF's Believe It or Not; there's no telling where this will go but please keep it between the ditches, if you catch my drift...

From AP June 4 2022

World’s largest plant is a vast seagrass meadow in Australia

WASHINGTON (AP) — Scientists have discovered the world’s largest plant off the Australia coast — a seagrass meadow that has grown by repeatedly cloning itself.

Genetic analysis has revealed that the underwater fields of waving green seagrass are a single organism covering 70 square miles (180 square kilometers) through making copies of itself over 4,500 years.

The research was published Wednesday in Proceedings of the Royal Society B.

Scientists confirmed that the meadow was a single organism by sampling and comparing the DNA of seagrass shoots across the bed, wrote Jane Edgeloe, a study co-author and marine biologist at the University of Western Australia.

A variety of plants and some animals can reproduce asexually. There are disadvantages to being clones of a single organism — such as increased susceptibility to diseases — but “the process can create ‘hopeful monsters’” by enabling rapid growth, the researchers wrote.

I think Hopeful Monsters would be a great name for a band.

Forest made of one tree The Trembling Giant, or Pando, is an enormous grove of quaking aspens that take the “forest as a single organism” metaphor and makes it literal: the grove really is a single organism. Each of the approximately 47,000 or so trees in the grove is genetically identical and all the trees share a single root system.Nov 10, 2010

India's mysterious gateway to the stars


By Shalbha Sarda 31st May 2022
.
From BBC.com

I
t was a week after the spring equinox, on a cloudless and hot afternoon. Perhaps a wrong time to venture out for sightseeing in Rajasthan's desert capital of Jaipur, but a perfect one to measure time with shadows cast by the sun. I strode through the frenzy of the Johri bazaar, the city's main market – its coral walls, delicate lattices and Mughal arches – sweeping by as I headed towards the Jantar Mantar, India's mysterious gateway to the stars.At first glance, this open-air complex filled with strange triangular walls and stairways to nowhere seems out of place: it's neither ornate like the City Palace that surrounds it nor intricate like the revered Govind Dev Ji Temple and Hawa Mahal nearby.

The site – a 300-year-old collection of 20 scientific sculptures called yantra that can measure the positions of stars and planets, and precisely tell the time – had bemused me since my childhood here in Jaipur, when the structures seemed like giant versions of the delicate tools I kept in my school geometry kit. But years later, as a professional architect, I could better comprehend their use. They are ingenious architectural solutions to understanding the mechanics of astronomy, as well as key tools for traditional Hindu astrologers to craft birth charts and forecast auspicious dates.

Powered by the wind........https://www.youtube.com/watch?v=HSKyHmjyrkATheo Jansen is an artist from Netherlands. But not any kind of artist! He creates sculptures, or “skeletons”, as he calls them, that “walk on wind”! By using yellow plastic tubes, the artist attempts to create “new forms of life”.

Over time he was able to make structures more resistable to wind and water. Theo Jansen’s ultimate aim is to release these beautiful “animals” at the beach and let them lead their own lives.

Best, Ben

She and her sister went out into the victory celebrations on the street when the family was waving on the balcony, they were in uniform so they weren't recognized and simply wanted to see what was going on.

Some Crazy Woman from Georgia is Reviving the Stuckey's Roadhouses

.

.
.
Stuckey’s is generally said to have started in 1937 when Williamson Sylvester Stuckey Sr., known as Sylvester, opened a pecan stand along Highway 23 in Eastman, Ga. It started long before that, according to his son, Williamson Sylvester Stuckey Jr., a businessman and former five-term congressman who went by Bill in his political career, Billy at home and Possum at Burning Tree, a golf club near Washington....Arguably it was the first Stuckey’s, and the first in a series of ideas that would become the roadside chain. “He could come up with 100 ideas a day and you had to figure out what was the good one,” Mr. Stuckey said. Noting that most customers were Northerners driving to Florida, “he realized tourists were the business,” he said. It was the dawning of the road trip.
.
.

Stuckey’s was so ubiquitous that the author Mark Leyner, in his 1990 book, “My Cousin, My Gastroenterologist,” described a drive through the Midwest as: “Corn corn corn corn Stuckey’s. Corn corn corn corn Stuckey’s.” Once claiming 368 stores in more than 30 states, each loaded with candy, cheap toys and cheesy trinkets, Stuckey’s became an essential experience of the American family road trip.

The Voyager 1 & 2 spacecraft are still operating and sending back data after being launched 44 years ago back in 1977. Voyager 2 has exiting the solar system (passed beyond the heliosphere, the limit of the suns influence), and Voyager 1 should do that within the next year, too. Pretty amazing.

The contemporary Viking 1 lander was lost in 1982 when it was mistakenly told to point its antenna down.

The first Soviet lander to finally make it to Venus in 1967 was quickly rebranded an atmospheric probe when it cooked and probably imploded during parachute descent.

The new James Webb space telescope has "actuators" that move the mirrors precisely to align all the separate segments to make one big, accurate mirror. They can move in 8 nanometer steps, as needed, working for years at the extremely cold temperatures. The same module has to also do coarse adjustments after launch, 20mm / 3/4 inch in total. Both coarse and fine adjustments use the same, single motor per actuator.
~~~
"These mirror actuators are one of the Webb's many new inventions. They enable the minuscule movements on the scale of nanometers that are necessary to achieve optical perfection. A nanometer is one billionth of a meter, or one millionth of a millimeter. To put this in perspective, consider that a typical sheet of paper is about 100,000 nanometers thick. Moreover, these actuators must operate reliably and repeatedly at the extreme "cryogenic" temperatures of only tens of degrees above absolute zero."
~~~
So I was wondering how could this work at all. Where would you start to make something like this! But it's reliable gearing and flexing structures in a 1.5 pound / 600 gram module.
