Kind of embarrassing. I, the supposed hot shot science guy, taking like 20 some minutes to figure out at what point between 3 and 4 p.m., the hours and minute hands on the clock form a straight line. Since at 3 p.m the needles form 90 degrees *, with the hours hand at 0 deg, and minutes needle runs 12 x as fast as the hours needle, we have a simple 12x-(90+ x)=180. But I got all mixed up considering radians, degrees, converting back and forth between different units.
*Seemed easier here to use degrees , rather than radians.

Ever had an idea that felt just so fundamentally radical that you thought that there has to be a flaw that you're overlooking? I having one of those moments today. I guess that I'll have to do the hard work to prove myself wrong. 
Edit: Found the first thing that I didn't consider already but I don't think that it's a showstopper.

The clearest sign of intellectual chemistry isn't agreeing with someone. It's enjoying your disagreements with them.
Harmony is the pleasing arrangement of different tones, voices, or instruments, not the combination of identical sounds.
Creative tension makes beautiful music.

All permutations of Richard Feynman are funny if you replace Feyn with Fine and Richard with Dick. Just Sayin'

Richard Feynman did in fact go by the name of "Dick." It was his common name used by friends, family, and colleagues.
And of course, the "Feyn" in Feynman is pronounced the same as "fine."
So, realistically, that already was the way it was.

now that i think about it other permutations may not be.

The governor, Gavin Newsom, imposed a state of emergency on Monday as officials cut power to 245 homes in the seaside community, about 25 miles (40km) south of Los Angeles, due to worsening land movement. The electricity provider in the region, Southern California Edison, shut off power to 140 homes on Sunday and another 105 on Monday, citing the risk of igniting fires.
‘Gigantic’ landslides hit California coastal town: ‘Watching their homes crumble’
https://news.yahoo.com/news/hundreds-coastal-california-homes-lose-201532932.htmlNice view from expensive houses that are built on unstable ground. They should have known that.
Rancho Palos Verdes is now grappling with buckling streets, buildings sinking and cracking and hundreds of families forced to leave their homes, said Janice Hahn, a Los Angeles county supervisor, at a news conference on Monday.
I've seen a similar situation on Soledad Mountain in LoJolla, Ca, where a water leak in a water main soaked the ground down grade such that a portion of the mount subsided with the road and several houses.

Due to heavy rain the last two years, a slip plane was lubricated and the area started slowly sliding to the sea. There was enough water in the saturated ground that it seeped down to another, previously unknown, slip plane, about 600 feet deep.
With the two active slip planes, some areas were/are traveling as much as 1 foot per week.
Sounds terminal to me.

I've always liked Tom Hanks' combination of his first initial and last name - THanks. I can just imagine his email signature.
Thanks,

COVID days are still with us.WWGD said:I found an old box of face masks from the Covid days. I thought Id use them as eye covers for sleeping. Snag: I have ears. Masks were on the snug side and width of my face around /including my ears is larger than around my mouth.
I bought a box of paper-ish masks, 50 ea. per box, and from 3 years ago, still have most or half of them still in the box.
Cloth masks can be made, for those individuals motivated to do it. And no need for sewing machine.

Still comes up in news reports. Summer surge we've been informed; and revised vaccines now being issued. Enough to convince me. I do not currently know the general data on hospitalizations and deaths.WWGD said:By what account is Covid still a major issue?

WWGD said:Wow, pickpocketing, tourist theft still a major issue. Some have taken it onto themselves to fight them, take them on in several YT channels.
While I don't wish to undermine any real threats (pickpocketing and tourist theft do in fact occur, unfortunately), some YouTube videos of such things are staged. Maybe (certainly) not all, but some.
(Why would anybody stage a theft and post it to YouTube? I don't know. Pick a reason. It's a lot easier to stage an altercation than stumble upon a real one, I suppose.)
I guess my point is that when watching such videos, keep a skeptical eye open.

Valid point, but these didn't seem staged, as, among other things, local authorities were involved, and I verified they were the real ones.collinsmark said:While I don't wish to undermine any real threats (pickpocketing and tourist theft do in fact occur, unfortunately), some YouTube videos of such things are staged.
