Amateur Astronomer Discovers 80th Moon That Orbits Jupiter - Veterans Today | Military Foreign Affairs Policy Journal for Clandestine Services

Amateur astronomer Kai Ly is on a roll. They rediscovered four “lost” Jupiter moons last year. Now, Ly has located a previously unknown moon orbiting the biggest planet in our solar system.
“I’m proud to say that this is the first planetary moon discovered by an amateur astronomer!” they posted June 30 in a message at the Minor Planet Mailing List (MPML), an online community of the world’s leading amateur astronomers.
Using old telescope images, Ly was able spot the unnamed satellite orbiting Jupiter, which is nearly 385 million miles from Earth. The distant planet has at least 79 moons now 80 some so small and indistinct they can only be detected by a large telescope one month of the year. ....

The easiest way to fool artificial intelligence


Feedback is our weekly column of bizarre stories, implausible advertising claims, confusing instructions and more

This is not an apple
Another week, another artificial intelligence going decidedly off-piste. We recently mentioned the autonomous video-interviewing system that appeared to be grading candidates on the strength of the bookcase behind them (27 February). Now a paper published on the website of the company OpenAI reveals how CLIP, a neural network system that learns to recognise visual concepts through being fed verbal descriptions of them, can be spoofed simply by overlaying an image with text declaring it to be something else.
Stick a sticker on an apple declaring it to be a different apple product, an iPod, and the AI says it is an iPod 99.7 per cent of the time. Plaster dollar signs on a picture of anything, from a poodle to a chainsaw to a horse chestnut, and, with a charmingly artless naivety, CLIP most ....

Narinder Kapany: Unsung hero who coined term 'fibre optics' and touched billions of lives : The Tribune India


New Delhi, January 18
Fibre optics – say the words and people think of high-speed internet cables. More knowledgeable ones might also know it is the science of transmitting light through flexible fibre. But very few would even have an inkling that the man who coined the term “fibre optics” was born and educated in India.
Fewer still realise that the contributions of Narinder Singh Kapany find application in the lives of billions of people on this planet, in ways big and small.
Kapany died in the US last month, a trailblazer in the field of fibre optics, a role model for optical engineers but an unsung hero, unknown to so many whose lives he touched with his innovations.    ....

Narinder S. Kapany, 'Father of fibre optics' dead


When Narinder S. Kapany was in high school in the 1940s in Dehradun, his science teacher told him that light travels only in straight lines. By then he had already spent years playing around with a box camera, and he knew that light could at least be turned in different directions, through lenses and prisms. Something about the teacher’s attitude, he later said, made him want to go further, to prove him wrong by figuring out how to actually bend light.
By the time he entered graduate school at Imperial College London in 1952, he realised he wasn’t alone. For decades researchers across Europe had been studying ways to transmit light through flexible glass fibres. ....
