Why is the U.S. still not using the metric system?

[Arakhor]

Not your ignorance, Domination, your militant disregard for your ignorance.

 

[ParadigmShifter]

This thread just got alot more amusing when Paradigmshifter turned it into a math contest between conservatives

Let's see how good they are at general transforms then

If you want to map

a to b

onto

c to d

how would you do that? This tests your ability to actually "do the math" rather than remember formulae.

For C to F conversion a to b is 0-100 and c to d is 32-212.

Go go go, you conservative hotshots!

EDIT: I'll go and get beer, in the meantime. I'll mark your efforts when you are done. I REALLY wanted to be a maths teacher, maybe I should have gone to more lectures (I went to 8/200 I think in my last year) when I was a student.

Umm... Look at what I posted perhaps...

I actually think that's correct, unless everyone who has taught me is wrong.

Unless I just forgot what it was. Feel free to enlighten me.

Maybe the -32 is BEFORE the fraction? After thinking it through, that would make more sense.

No need to insult me in any case

I ADMITTED possible ignorance.

I have no idea. I suck at Math.

 

[ParadigmShifter]

Oh just give it a try. Math isn't that hard, despite what Barbie says.

That would be the case if it really was just military equipment. But it's also a lot of other stuff Americans produce. Although Americans have mostly given up producing anything of real value, they still manufacture some high tech equipment and if you need that you better have two sets of tools and screws and everything for a few pieces of equipment made in the US.

Sometimes they apologize, but sometimes there is not even that and you need to accept that you need a spacing of exactly 0.0195 inches to interface with the device.

Pretty much all lab grade stuff will be metric since scientists in the US use metric too. Almost all electronics is ISO. Hex, posi and philips are the same irrelevant of metric/ imperial. Almost all "american" cars you can buy in europe are manufactured in europe - hell half of them are designed in europe too - and you dont generally need imperial tools for them.

I cant really see needing a second set of spanners being a deal-breaker when you buy a jet fighter or a Harley.

I have to do it in school, and frankly I hate it, and I see little value in what I've learned for the past 1.5 years.

 

[ParadigmShifter]

Well it's elementary algebra and you should know how to do it.

I used to think trigonometry was useless too until I had to use it nearly every day programming 3D games.

 

[GhostWriter16]

I learned pretty much no algebra in Elementary.

However, I'm sure I could figure it out if I'd actually learned it recently.

I used to think trigonometry was useless too until I had to use it nearly every day programming 3D games.

I haven't even gotten to Trig yet

 

[Arakhor]

You're sixteen and you haven't yet done trigonometry?? What are your parents playing at?

 

[ParadigmShifter]

LOL no trig by 16

Massive fail.

EDIT: Hint for the mapping question - map a-b into the interval 0-1, same with c to d, that makes it a lot easier.

I'm in 10th grade, here we learn it in 11th.

The cutoff in NYS is at the end of the year (Basically, if you were born in '94 you'd currently be in 11th, if you were born in '95, you'd currently be in 10th, exc.) Obviously you could fail or skip a grade, but this is just in general. I was born on Jan 21 '95 so that would already put me in 10th, but in Florida the cutoff is Sept 1, and I started school while living in Florida, so I was easily NOT making the original cutoff.

EDIT: Maybe you guys learn it quicker in England, but in America its in 11th grade.

 

[Chukchi Husky]

I never did trigonometry until I tried A level maths.

 

[ParadigmShifter]

10th grade is 15?

We learn trig when we are 12 or 13. It's vital if you want a career in engineering or science.

EDIT: Well we used too - maybe education standards have slipped. Apparently they don't even teach long division anymore...

Rubbish. The National Curriculum has not changed that much in just 15 years.

 

[Lillefix]

I remember when I was going to learn trigonometry. I thought it some kind of advanced and exciting geometry. Then it turned out it was just triangles. I'm still a bit disappointed.

 

[ParadigmShifter]

Well the "tri" bit of the word "trigonometry" may have been a hint

 

[Ajidica]

I learned trig in Introduction to Geometry, which was 10th grade.

 

[Chukchi Husky]

I guess that's why I failed at every exam I did.

 

[Joecoolyo]

I think what Dommy is referring to is that you learn the basics of Trig in Geometry (9th grade), and all rest in Pre-calc (11th), which is what I'm doing currently.

 

[ParadigmShifter]

There's really not a lot to trig except "hey, we can have angles greater than 90 degrees!". (I mean pi/2 radians, of course).
