It's 100°F and is forecast to be 104°F later this afternoon here in my town in Kansas.
It's 103°F and now forecast to be 105°F. Dang.dlgoff said:It's 100°F and is forecast to be 104°F later this afternoon here in my town in Kansas.

Was that the one about the doorlocks. Or was it morlocks?gmax137 said:ask H G Wells

I've heard it pronounced chi-per. Chi as in the Greek letter ##\Chi##.fresh_42 said:Life would be much easier if we were allowed to translate names. I haven't managed to figure out yet how Kuiper is pronounced. Cooper would be so much easier. Or Küfer to annoy the English.
Ask Simmons etc al, they're just not creatures of the night, I guess.fresh_42 said:... or Gauß.
..., annddd it's fixed itself. Like Schultz, I did nothing....Bystander said:Any one lose their e-mail sometime in the last three hours*? It simply will not open.
*Last three hours is something between 0900-1200 MDT.
There's another one that's not open, but seems incredibly hard: there are only 3 perfect squares in Fibonnaci. Might be too hard.nuuskur said:Swallow the pride, admit you messed up and give another nut to crack (but make sure it's known to be crackable)
The usual nutjob approach is Collatz. But why not let him prove that there are infinitely many primes and that there is only one prime triple? Playing around with Legendre symbols can also initiate his interest in number theory. Or let him prove that what he probably calls prime is in fact irreducibility. Let him prove that both are equivalent.WWGD said:There's another one that's not open, but seems incredibly hard: there are only 3 perfect squares in Fibonnaci. Might be too hard.
Every darn day it seems like the humidity is 70%+ in my city in Virginia.dlgoff said:It's 100°F and is forecast to be 104°F later this afternoon here in my town in Kansas.
Humid days and nights are not a new phenomenon in Virginia.kyphysics said:I wonder if this is related to climate change?
I grew up in Maryland. I though the summers were often more humid there. I remember lots of 95% humidity.kyphysics said:Every darn day it seems like the humidity is 70%+ in my city in Virginia.
I wonder if this is related to climate change? . . . I don't mind heat if it's not humid along with it. I hate humidity! It gives your skin an icky feel and causes mold/fungus growth.

I've also heard " Concave/Convex Up/Down. Not helpful.nuuskur said:2nd derivative negative implies convex ...
I hate school math. Why are concave functions called convex???!![]()
To let himself out? That is very bad fire safetyWWGD said:Strange setup in my friend's place. He uses keys to _ exit_ his apartment.
So to get back in?fresh_42 said:It prevents you from forgetting the key. And in case of fire, just keep the key within the lock.
Yes. That's the plan.pinball1970 said:So to get back in?
In the event of a fire the first priority is to get yourself and the family out.fresh_42 said:Yes. That's the plan.
I agree. But I have often seen exterior doors with deadbolts, and people keeping the deadbolt key inserted on the inside. I think this is acceptable, as long as you don't leave, and lock the deadbolt behind you with other people still inside. Doing that is certainly a dangerous act.pinball1970 said:It should be as simple as possible.
