Post and discuss interesting articles & videos about science and technology.

You don't need to be an expert - just interested in the wonders of modern science, technology, and the history of these fields.

Please keep it rational, and post articles from reputable sources.
Try not to editorialise headlines and keep the copy to just a paragraph with a link to the original source. When quoting excerpts from articles, I think the best method is to italicise the copy, and include a link to the source.

Have some fun with your comments and discussions... just keep the sources legitimate.

Other threads:
The Break Room has a number of other popular threads, so there is no need to post material here that is better suited to these other threads:

- Covid19-Coronavirus updates and news
- Conspiracy Thread Free For All
- The *religious* discussion thread


Please enjoy!

Quantum internet signals beamed between drones a kilometre apart

Entangled photons have been sent between two drones hovering a kilometre apart, demonstrating technology that could form the building blocks of a quantum internet.

When a pair of photons are quantum entangled, you can instantly deduce the state of one by measuring the other, regardless of the distance separating them. This phenomenon, which Albert Einstein dismissively called “spooky action at a distance”, is the basis of quantum encryption – using entangled particles to ensure communications are secret.

The achievement marks an important step towards a quantum internet, says Siddarth Joshi at the University of Bristol, UK. He agrees that drones could become the final chain in links from one part of the world to another, such as from your local relay station to your home or vehicle. “You’re driving around in your car and you want to maintain secure quantum communications, so you have these drones flying around behind you,” he says.

Myungshik Kim at Imperial College London believes that engineering such complex optics into moving drones, especially given that small rotational differences can make it extremely difficult to maintain quantum connections, represents a strong technical advance.

Zebra stripes, leopard spots and other patterns on the skin of frozen metal alloys that defy conventional metallurgy

60056d390e45f.jpg


While it is fascinating that living creatures develop distinct patterns on their skin, what may be even more mysterious is their striking similarity to the skin of frozen liquid metals.

Pattern formation is a classic example of one of nature's wonders that scientists have pondered for centuries. Around 1952, the famous mathematician Alan Turing (father of modern computers) came up with a conceptual model to explain the pattern formation process of a two-substance system. Such patterns are also called Turing patterns thereafter.

Egypt unveils 3,000-year old coffins in latest discovery at Saqqara necropolis south of Cairo

Egypt has unveiled an archaeological discovery at the Saqqara necropolis, south of Cairo, which could "rewrite the history" of the New Kingdom period.

The find includes 54 wooden coffins that can be traced back 3,000 years to the New Kingdom period, which spans about 1539 to 1075 BC.

Key points:
  • The find includes 54 wooden coffins that can be traced back 3,000 years
  • The funerary temple of Queen Neit was also discovered near the pyramid of her husband, King Teti of Egypt's 6th dynasty
  • The archaeologist who headed the mission says the finds will rewrite the history of the New Kingdom period

-----------------------------

50 ancient coffins uncovered at Egypt's Saqqara necropolis

The wooden sarcophagi, which date back to the New Kingdom period – between the 16th and the 11th century BC – were found in 52 burial shafts at depths of 10 to 12 metres (40 feet).

Hawass said the funerary temple of Queen Naert, the wife of King Teti, as well as three warehouses made of bricks were also found on the site.

Physicists Observe Fleeting 'Polaron' Quasiparticles For The First Time

Polarons are important nanoscale phenomena: a transient configuration between electrons and atoms (known as quasiparticles) that exist for only trillionths of a second.

These configurations have unique characteristics that can help us understand some of the mysterious behaviours of the materials they form within – and scientists have just observed them for the first time

What Is Google Dorking And How To Use It

Google has become synonymous with searching the web. Many of us use it on a daily basis but most regular users have no idea just how powerful its capabilities are. And you really, really should.

Google dorking is basically just using advanced search syntax to reveal hidden information on public websites. It let’s you utilise Google to its full potential. It also works on other search engines like Google, Bing and Duck Duck Go.

A ‘Super-Puff’ Planet Like No Other – As Big as Jupiter but 10 Times Lighter

Helium-in-the-Eroding-Atmosphere-of-an-Exoplanet.jpg


The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found.

This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM’s Institute for Research on Exoplanets (iREx) suggests that gas-giant planets form a lot more easily than previously believed.

Hindenburg Crash: The End of Airship Travel

Roy7KHigvw8auXTPM8sztG-1024-80.jpg.webp


On May 6, 1937, the German zeppelin Hindenburg exploded, filling the sky above Lakehurst, New Jersey, with smoke and fire. The massive airship's tail fell to the ground while its nose, hundreds of feet long, rose into the air like a breaching whale. It turned to ashes in less than a minute. Some passengers and crewmembers jumped dozens of feet to safety while others burned. Of 97 people aboard, 62 survived.

At the time, the Hindenburg was supposed to be ushering in a new age of airship travel. But the crash instead brought the age to an abrupt end, making way for the age of passenger airplanes.

The crash was the first massive technological disaster caught on film, and the scene became embedded in the public's consciousness. A horrified radio reporter's exclamation — "Oh, the humanity!" — has since become somewhat of a catchphrase. Speculation about the cause of the crash has been the subject of numerous books and movies.

LZ-129 Hindenburg was the first airliner to provide regularly-scheduled service between Europe and North America.

While the airship is better remembered for the fiery Hindenburg disaster of 1937 than for its many technological achievements, it was the fastest and most comfortable way to cross the Atlantic in its day.

A great source of information on the LZ-129.

But they dont use Hydrogen anymore?
Helium is where it’s at.

Thanks for the “agree” @CraigD

Reading it, i feel could been portrayed as a dig to point.

You may be right; How the hell should i know?
I’m just saying, regards to topic... Helium reacts less...

But is Hydrogen the answer? Read some People swear by it. You started it with the metaophor.
Apparently, when i tell people Hydrogen combusts;
they say; “Well, so does Gasoline.”

I'd actually be very happy to see the return of giant helium airships.

I know that AG Zeppelin were developing them about 20-years ago for passenger cruises and Boeing/NASA were looking into using them for transportation.

I have not heard much recently, but I'll look into it ;)

i meant fuel... Replace gasoline. Sustainable. Cheap.

A poorman’s Tesla

Here in U.S. it couldnt be tamed... Despite a lot & cheap.
I believe all the car companies killed Hydrogen cars,
BEFORE Tesla took off — Maybe bias of that blimp may have contributed... Idc really, i’m more Tesla fan :)

I dont care if Teslas dont have that “new car smell”
Bring on technology (Sorry, Hydrogen lost to Lithium Ion

How airships could return to our crowded skies

Airships lost out to conventional aircraft after a series of disastrous crashes. But now safer technology could be the key to their return.

NASA Seeks Comments on Possible Airship Challenge

imagestechnology20141125tech20141125-16.width-1024.jpg


Nov 25, 2014

NASA is considering issuing a challenge for developing stratospheric airships that can break records for duration of flight at high altitudes.

Airships aren't just powered balloon-like vehicles that hover above sporting events. Researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, are floating the idea that airships have potential for important scientific and commercial uses.

What an amazing view!

I really feel for Jim Lovell. He spent years of his life training to land on the Moon but missed his chance because of the Apollo 13 accident.

Lovell had previously flown on Gemini 7 in 1965 and Gemini 12 in 1966.

In 1968 he piloted Apollo 8 on the first orbit of the Moon, and then commanded the 1970 Apollo 13 Lunar landing mission which infamously aborted en route, circled around the Moon and returned safely to Earth.

So close yet so far.

Still, he got to see the Moon close-up, twice!

As the planet warms faster, scientists study controversial ways to lower temperatures

A team at Harvard University this summer plans to conduct the first of a series of highly controversial tests of what’s known as solar geoengineering, a way to reduce global warming by spreading particles in the atmosphere to reflect sunlight back into space.

BB1cPU1H.img



If an advisory board authorizes them to proceed, the scientists plan to travel in June to a remote part of northern Sweden, where they’ll launch a giant balloon into the stratosphere to test whether they can adequately maneuver an instrument-filled gondola suspended below. If all goes well, the team later this year plans for the first time to inject a small amount of calcium carbonate — a common substance found in rocks — into the atmosphere to better understand how the chemical compound might be used to moderate temperatures on the ground.

Long considered too risky, solar geoengineering is now being more seriously considered as the threat of climate change grows more dire. But critics say such a test, which would spread a few pounds of the particles about 12 miles above ground, would set a dangerous precedent and open a door to more radical experiments that could ultimately cause grave harm to the planet.

It's been said, 'be careful what you wish for'. Global Warming may lead to Global Cooling (Ice Age) if too aggressive counter-measures are taken (or non at all). :oops:
