Everywhere you read they claim DOGE has been dis-mantled. I hope not.

@HymanKaplan Thought you might appreciate this. 13% of students who took a UC San Diego math assessment could not perform at first-grade level, and 25% of kids got the equation 7 + 2 = [ ] + 6 wrong.

College kids’ math skills worse than ever, California finds — blame our pass-the-buck public schools
America has plenty of talented people — but a UC San Diego study finds our schools are failing to educate them. And everyone involved just gets a pass.nypost.com

Oh no, now Cord!HaymanKaplan, I still want you to explain to me What 96 Coe means for glass. I don't fire glass in a kiln although I would like to learn, just to old to get into it. The formula is what I would like for you to explain to me.. I don't know how to post a picture but the formula Coefficient of Expansion, meaning the glass expands at the rate of 96 x10 with a minus 7 by the top of the zero, then a / small zero then C. If you don't want to mess with old Cord, that's ok, but that formula has bugged me ever since ! I saw it! Thanks
Oh wait! That was on final Jeopardy last night.@cordmaker 74
Sorry if you asked me before, I must've missed it.
It means the coefficient of linear thermal expansion. Meaning how much the glass will expand per degree of change in temperature. So, let's say you had a glass "brick", that was 3 inches by 4 inches by 6 inches at 12 degrees Celsius and you want to see what the dimensions would be at 70 degrees Celsius.
The COE of regular plate glass is 9 X 10^-6 (9 times 10 raised to the power of negative 6) per degree of difference in degrees Celsius
Calculate for each dimension:
For the 3 inch dimension raised by 58 (the difference between the starting temp 12 and ending temp 70) degrees Celsius:
3 inches times (1 + (9 X 10^-6 X 58)) = 3 X 1.000522 = 3.00157 inches
Then do the same for the other two dimensions
4 inches times (1 + (9 X 10^-6 X 58)) = 4 X 1.000522 = 4.0021 inches
6 inches times (1 + (9 X 10^-6 X 58)) = 6 X 1.000522 = 6.00315 inches
So your brick, which was 3 by 4 by 6 at 12 degrees will be 3.00157" by 4.0021" by 6.00315" at 70 degrees.
Just for fun, let's say that standard soda lime glass didn't HAVE a melting point (yes, I know, that would definitely change the COE but bear with me), and you heated that brick up to 1,000,000 degrees Celsius, what would the dimensions be? LOL
3 X [1 + (9 X 10^-6 X 999,988)] = 30
4 X [1 + (9 X 10^-6 X 999,988)] = 40
6 X [1 + (9 X 10^-6 X 999,988)] = 60
So your brick, at 1,000,000 degrees Celsius would be a very large (but not very dense) 2 1/2 feet, by 3 feet 4 inches, by 5 feet.![]()

Hope this helps.
Well, will the DOJ re-indict Comey and James? I'm hoping they continue with full force.

With your math knowledge, why aren't you a suoerdooper type of corporate executive?It's completely out of my field. I was just trying to demonstrate what it meant mathematically for cord because he asked. And honestly, when am I ever going to turn down the chance to do math. LOL I would think, that in terms of glass working, it would mostly apply to folks that do leaded stained glass work etc.
No coloring, unless it's the area under a curve, after you calculate said area first. And HOW DO WE DO THAT?
Anyone? Anyone? Anyone? (you use the antiderivative via integration LOL)

Like bridges & roads. Particularly noticeable when roads buckle in the heat.Yeah, engineers have to be well versed in COE especially when building structures/buildings in areas where there is a broad range of temps throughout the seasons.
Some here don't shop at Kroger due to checkout issues. Others don't shop at Wal Mart. So where do you shop? I don't have a problem with either. DW does 90%+ of the grocery shopping.One more reason to add to why I already don't shop at Walmart. The last time I did any real shopping there a few years ago, they refused to open checkout lanes with lines nearly 20 people long (that you could see, as the lines went down aisles and into clothing racks) and several employees standing around talking. I asked if they were going to open any registers. When they said no I left my cart and walked out. Others did the same.
I would've gotten the employee names, then gone up to customer service and returned ALL of it. They put their hands all over it. They can put their hands all over it again as they put it back on the shelf. Filing a complaint with the company wouldn't have done much good, if that's what they're doing nationwide.
