"Please don’t get the wrong idea that this is a point of controversy within physics!"
I was a little surprised by her comment but perhaps generating controversy is her actual point. It seems to me that with the long-standing and seemingly insurmountable gulf between QM and GR there needs to be more controversy—not less.
I've always considered >c discussions and arguments speculative and hypothetical and my view hasn't changed but with the QM/GR elephant in the room perhaps it's time to remind ourselves of a similar controversy. When Galileo proposed his controversial theory that likely >99.9℅ of the establishment was against him or thought him crazy.
I don't have anything to add to the topic, but I wanted to ask you about your usage of this character: ℅
Obviously, you meant to use the percent sign (%), but instead have used the "care of" sign (℅). This is the second time in a month I've seen this error, and I'm curious how it can occur.
I did just notice that it's possible to type it on an Android keyboard by long pressing the percent sign. That seems challenging to do by accident. I'm curious if there's another way to easily type it by accident.
Well, I've looked again and I'm not much further ahead. OpenBoard's help docs are essentially nonexistent, it assumes a standard AOSP Android keyboard so help shouldn't be necessary but there are differences compared with Google's GBoard. Incidentally, my reason for using OpenBoard is that it doesn't spy on one like
Google's GBoard.
The only way I can see to get the "care of" character, '℅', in OpenBoard is to use the number toggle and then select the alternate list of characters. As I said this is different to GBoard which allows one the choice between '‰' and '℅' in its long-press of the percent key.
In summary I can't see how I could have entered it from the keyboard without toggling the complete change of characters for the keyboard layout I was using and I don't think I did that—but then I must have. Either that or it's the result of spurious characters arising from hitting multiple keys at once that I mentioned in my last comment.
I hope that helps but I'm still not satisfied with what I've found for the reason that I often want to use Unicode characters that are not on the default keys and I'd to extend that list but it doesn't seem possible. At present, my only solution is to use a separate Unicode app to drop the character in and that's a bit of a pain.
Thank you for pointing that mistake out, I just didn't notice it (the phone is set to small font).
The message was sent from the same Android phone I'm using now. Moreover, I'm still not sure how it happened because the KB app I'm using is OpenBoard and its long-press is '‰'.
I'm curious too because OpenBoard only has the one long-press option (as above) unlike GBoard which has two—the first being '‰' and the second the "care of" sign. Trouble is that GBoard is normally disabled [not just deselected] on this phone and I had to re-enable it to check.
I've noticed occasionally that I've had 'strange' characters appear that do not seem to be long-presses when I've been typing in a hurry so there must be some option for selecting them that I'm unaware of.
It's late here now so I'll investigate later and get back to you when or if I find the answer.
