Massive Space Structures Have Surprising Connection to Quantum Mechanics Math | Space

In Hefei, China, the world's most advanced quantum communication network has reportedly been developed. The network is composed of three quantum devices and a central server, and it is as close to an unhackable quantum internet as we have gotten yet. The network shares some features with conventional communication networks, such as transmitting information through optical fibers. However, the light traveling in the quantum network comes in chunks whose quantum properties are used to encode information. This makes it impossible for an eavesdropper to intercept the information without being detected.

Quantum communication is a big advance in quantum networks, and it has the potential to revolutionize the way we communicate. The technology uses the principles of quantum mechanics to transmit information securely over long distances. It is based on the idea that if two parties share a pair of entangled particles, they can use them to transmit information securely. Any attempt to intercept the information would disturb the entangled particles, and this disturbance would be detected by the parties involved.

The development of this city-wide quantum communication network is a significant step forward in the field of quantum communication. It demonstrates that it is possible to build a large-scale quantum communication network that is both secure and practical. The technology has many potential applications, such as secure communication between government agencies, financial institutions, and other entities that require high levels of security. It could also be used to create a quantum internet that would be much more secure than the current internet infrastructure.

Carl Sagan on (why we should save kids from) central government's educational system

“…my experience, my experience is… you go, talk to kindergarten kids or first grade kids… you find a class full of science enthusiasts and they ask deep questions… What is a dream? Why do we have toes? Why is the moon round? What's the birthday of the world? Why is grass green?... These are profound important questions they just bubble right out of them... You go and talk to 12th grade students and there's none of that, they've become leaden and incurious… Something terrible has happened between kindergarten and 12th grade and that's not just puberty…”

Drawing the Line: The Life, Ink, and Cheeky Revelations of late Joe Matt's 'Peepshow

Joe Matt, the trailblazing American cartoonist renowned for his series "Peepshow," died of a heart attack on September 18, 2023, while channeling his life onto paper at his drawing desk. More than just a series of doodles, "Peepshow" was a diary in ink that delved into the dark recesses of Matt's psyche—addressing taboo topics like pornography and masturbation, while artfully exploring the complexities of mental health and sexuality. In "Peepshow," Matt offered a masterclass in vulnerability, serving up raw introspections and existential conundrums that made readers both squirm and resonate. And he did it all with an artistic panache characterised by meticulous lines, vivacious characters, and innovative panel layouts that would've made even the most prudish reader take a second glance. But Matt's work was more than self-absorbed introspection—it was a sociocultural critique wrapped in comic form. Born from the cultural currents of the 1980s a...

Lexical Lunacy: The Enigmatic Minds Behind the Oxford English Dictionary

In "The Dictionary People: The Unsung Heroes Who Created the Oxford English Dictionary", author Sarah Ogilvie found “an above average number of ‘lunatics’” among the Dictionary People. “Was it their madness that drove them to do so much Dictionary work, or was it the Dictionary work that drove them mad?” In the Oxford English Dictionary, a "Dr WC Minor"is referred to as a contributor only to be discovered later that, while he was an American surgeon, he was also a paranoid schizophrenic probable sex addict who had been committed to Broadmoor Criminal Lunatic Asylum after shooting a man dead. Another subeditor and reader, John Dormer – who seems from his quotations (“humbug”, “minx”, “hanky panky”) to have been rather fun – was admitted to Croydon Mental Hospital aged 35 in 1907, hearing voices. Eustace Frederick Bright, who started contributing as an 18-year-old medical student, was addicted to cocaine and morphine, and died of an overdose, aged 29, on the toilet fl...
