You think knowledge is useless? Interesting.
Without science like this we would not be able to use GPS. This is absolute proof of Einstein’s theory of relativity.
That is just one example of how ‘useless’ knowledge like this translates over to everyday life.
And Velcro. We have NASA to thank for Velcro. Or was it the aliens? I forget.
Velcro, no, not NASA.
Velcro was developed by some guy brushing burrs out of his dog’s coat. He looked closer to see why the burrs clung so tight to the fur, and discovered that the have tiny hooked ends.
NASA did great things, like powdered orange juice.
Velcro was invented bu a swiss guy trying to untancle burrs from his dog. Made Velcro to match the burrs.
