We had radar proximity fuses in use in AAA rounds during W.W. II, and they of course used vacuum tube technology. One of the members of our local ham radio club worked on that project in the ’40s. One of the challenges for his team was developing tubes that could withstand the 10s of thousands of Gs at launch. Ouch.
Now we have this, via an e-mail from my nephew. I find it fascinating, funny, and a little disturbing all at the same time. Ordinary rifles spin a bullet at 2K RPM? They missed that one by an order of magnitude or two. A rifle chambered for the 5.56 NATO round for example rotates the bullet at around 300,000 RPM, more or less depending on barrel length, rifling twist and bullet weight. But as I often say; what’s an order of magnitude (or two) between friends?
It is very telling, if not entirely predictable, how they smear the general public in the article– government = good, whereas regular citizens = dangerous or at least troubling. They of course have it entirely upside down and backwards in that department.
