I don't get it, why is metric better?

_I_ was the poster, _I_ KNOW I posted an integer "1"

(Huge sigh). Y'all have gone far afield. J. Clarke wondered if the metric system is why European students do better than Americans on math tests. [Do they really?] L Blanchard replied "Absolutely! Other students do not have to deal with fractions."

I only wrote the math problem to illustrate that the metric system does not free students from dealing with fractions.

Now you guys are sounding like this: :)

Integers are not much use when measuring stuff.

Immaterial. It was/is counting. I should know, I was the poster...

Granted, one sees stuff like that a lot on internet stores...I had a heckuva time figuring out the thread diameter/pitch when trying to order a replacement sight glass for a little HF air compressor. Turns out it appears the threads in the casting are 3/4" NPT because a standard pipe plug will not leak but I've tried four different sight glasses and not a one will seat tightly enough to not leak. Hence, I drilled/tapped a

3/4" plug with a 1/8" NPT offset where the bottom is at the mid-point and now have a level check! :)

But the key there is mostly _you're_ choosing which to use for specific purposes; the argument (at least mine) against is mandated changing of "ordinary" day-to-day-living things just for the sake of doing so. I have no quarrel against what anybody chooses to use; I do resent the thought of US bureaucrats in DC using threats of cutting of federal hiway dollars to states to force compliance in change road signs, for example.

Glass or plastic, we no longer see soda bottle vending machines, like we used to. I actually recall a few in odd places.

[Leon]

sorry, I only now realized you did not say repeating decimal "points" ;~)

There are a couple stashed in offices around town I recall altho like the one you mentioned I think it's been probably 20 yr since they were anything more than "yard art". There's one of the chest types still on the showroom floor at the Chebby dealership but it's under about 3" of dust and old catalogs now... :)

Glass is pretty much a bygone; cleaning and recycling is just too expensive. About all I see any more are imports coming up from Mexico by the immigrant population bringing them back -- they're popular mostly because as somebody else noted elsethread they're mostly sugar-based with less fructose. (Some claim can tell by taste; the double-blind tests I've done similar to Sir Fisher's on the lady serving tea as to whether the milk was added first or later were unable to show a statistically-demonstrated case it was true for most).

But most likely 1 lb means 1 lb.

Either way,

We were talking about +1 to a statement, not apples.

Actually I made the, do not have to deal with fractions comment.

Perhaps, but the original answer was not in final form as taught in school, when I was in school. It would have been graded as wrong for not reducing.

[Leon]

Wow, I doubt, given my answer and your answer, your calculus instructor would agree with you. Take you answer out of context and yes he would.

But If you can't understand that my answer is precisely correct it may say a lot about your instructor or what you actually got out of that class.

FWIW referencing another source means nothing if your answer is still wrong.

[Leon]

Scratching my head and thinking back a bit, I do actually recall, recently, a plastic bottle vending machine, IIRC it took dollar bills.

But I was thinking where you put the money in a grab the bottle from a slot. The few recent ones I recall drop the soda or water much like a bag of chips is dropped and then you reach inside, to the bottom, through a spring loaded door.

I normally see these outside restrooms at shopping malls.

Gonna guess the "hoo" in that case was the burial mound itself.

This (the replacement of coal by natural gas in electric generation) is very reminiscent of the replacement of steam locomotives by diesels in the 50's. Basically, given the labor of shipping it, preparing it for use, and disposing of the ashes, coal has to be much cheaper than natural gas (now) or diesel (then).

With natural gas looking to be cheap for the forseeable future, it seems unlikely coal will ever be economical again, just like it wasn't for locomotives.

Not really. Assume an apple is the elementary unit of appleness. All you need to know is the mass of an apple, then you can figure the mass of 6.022e23 of them, and divide that into 40kg to find what fraction of a mole it is.

It'll be a tiny number :-)

Interesting. Around here can vending machines have pretty much completely disappeared. It's all plastic bottles. I kind of think it's because so many people want things other than soda, and you can put water, or juice, or other things that don't usually come in cans into them.
