This was used to restore the audio speed to restore frequencies, but...

I love this: such a misunderstanding in what someone in the 19th century saw as 500 somethings, and we see today as 250 somethings, shows that even the apparently intuitively clear understanding of what a description means can be very wrong. (I wonder what this means for more vague descriptions from further in the past and other societies and dead languages.) Or, that measurement and terminology problems, which every developer will be familiar with, are an age-old human problem!

Shared context help tremendously (e.g. talking about a physical location), and concerns are clear, so there's only a few things a person might mean. In general, I think human beings do much work in calibration, along with their instinctive compulsion to conform. It also suggests one explanation of their intolerance and fear of difference. The uncanny vall=y is most dangerous, when communication seems oc%ur, without a cautiona&y flag that a check is ne@d#d.

- _5gzd 5y agoOh I just saw your comment: https://news.ycombinator.com/item?id=30561474 https://news.ycombinator.com/item?id=30561474 James Randi is a scam artist. There's plenty of accepted psychics, James Randi is like the (lazy) normalization of skepticism for people who don't want think (critically). Mmm, I get if you want/need to do that. But just go to reddit/remoteviewing and give it a try. You can see through that bullshit that James Randi is...But I get if you'd rather James Randi decide for you what you should think or not. "Safer", right? hoho :)
- teddyh 5y agoYou found a comment from almost two months ago which you wanted to reply to, but can’t, since the thread has long been closed. So your solution was to track down the person who wrote that comment, find a recent comment they wrote about an unrelated topic, and try to resurrect the now-dead flamewar in an unrelated thread?
- _5gzd 5y agoIt's not about flamewar. It's just personally important to me. Not resurrecting any flamewar, if you saw war there it was only in your attitude...I'm just saying what I wanted to say in response to what you said. I didn't see your comment before then. If you don't like people's responses to what you say online maybe be more considerate of how they might respond before you say something online: I posted a lot of data, and you just invoked some general "impossibility defense"... I feel scared that people won't see my work because of that. So it hurts, like trashing my work without reading it. It's irresponsible to blanket dismiss something, and speak as if you know enough to dismiss, when you don't. There's no need to be mean like that. I think it's better if you're nice and/or substantial.
- pessimizer 5y agoI don't know that it's all that deep. Hz measure cycles, but a cycle is a movement and a reversal of that movement. It isn't like we can't see that, it's just that "simple vibrations" didn't turn out to be that useful of a term. edit: hell, a circle is 2π radians. That's two of something in a cycle.
