He did not patent the machine because he wanted to “teach the world to sing”. He earned nothing from the billion dollar industry his invention has spawned and has no regrets. The image below is of him and the first karaoke machine ever made.

Mimas: Small Moon with a Big Crater

Posted on Posted in NASA, TweetTagged , , , Leave a comment

Whatever hit Mimas nearly destroyed it. What remains is one of the largest impact craters on one of Saturn’s smallest round moons. Analysis indicates that a slightly larger impact would have destroyed Mimas entirely. The huge crater, named Herschel after the 1789 discoverer of Mimas, Sir William Herschel, spans about 130 kilometers and is featured here. Mimas’ low mass produces a surface gravity just strong enough to create a spherical body but weak enough to allow such relatively large surface features. Mimas is made of mostly water ice with a smattering of rock – so it is accurately described as a big dirty snowball. The featured image was taken during the closest-ever flyby of the robot spacecraft Cassini past Mimas in 2010 while in orbit around Saturn. via NASA https://ift.tt/3vOenuQ

Wikipedia article of the day for May 31, 2021

Wikipedia article of the day is Scorpion. Check it out: Article-Link Summary: Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. There are over 2,500 described species. They mainly live in deserts but have adapted to a wide range of environments. Most species give birth to live young, and the female cares for the juveniles while their exoskeletons harden, transporting them on her back. Scorpions primarily prey on insects and other invertebrates, but some species take vertebrates. They use their pincers to restrain and kill prey. Scorpions themselves are preyed on by larger animals. Their venomous sting can be used both for killing prey and for defense. Only about 25 species have venom capable of killing a human. In regions with highly venomous species, human fatalities regularly occur. Scorpions with their powerful stingers appear in art, folklore, mythology, and commercial brands.
