For example, I think most know 1/4 = .25, 7/16 = .4375 and 1/8 = .125 ... the kind of thing most of us I suspect learned early in school. However, 4/32 or 14/32? I have to think for sec as to what that is. I guess if a person had a whole list of sizes and a couple couldn't be reduced from 32nd, it would be quick way to tell which is bigger/smaller for easy comparison at a glimpse. Oh well, not meaning to hijack, just a curiosity because I have seen people do that too.

Or that 7/16 = .4375? People don't reduce those fractions because it makes meaningful, quick comparisons possible. If I've got one thing that's 3/32 and the other that's 16/32 I'm not going to reduce the second one to 1/2.

How often do you really think the average person deals with fractions beyond the really, really dirt-simple poo poo like 1/2, 1/3, 1/4? I'm serious. Stop and really think about it. At this point everything is calculated out electronically 99% of the time for people. The only place I can really think of where you're using fraction-based math at all is in cooking, and a shockingly low percentage of people actually cook their own meals at this point (and no, warming up the Hot Pocket yourself is not "cooking"). Even then, most just follow the recipe. Try asking someone how to do basic fraction math, like converting the recipe for a cake to make half of the serving that it's written for (dividing everything by two). Hilariously enough the people I've seen with the best fraction-based math are potheads. Your average stoner can tell you how to break up a quarter ounce among 7 people without batting an eyelash.

People can relate to that (the more worked down fractions) easier a 32nd. Breaking something down to a x/4 or even an x/8 is at least something someone with basic elementary math skill can at least relate to. 1/4? Sure.. and 1/8 is twice as small. OK, people can wrap their heads around that. Bring out a 32nds? How does that not make your eyes glaze over unless you're doing a direct comparison with a few of which that is the lowest common denominator? It just becomes goobeldy-gook at that high of a fraction to most. Heck, In my business I deal with cross section of people from dirt simple farmer Jed, Professional Engineers and machinists. I can tell you that the easiest way to explain things to people is either with the lowest denominator fraction OR, even better, a decimal. Generally if it's smaller than a sixteenth for purposes of discussion it goes to "just a bit more than a sixteenth" than, say, "3/32". At that point a decimal is probably the best way to describe because everyone seems to grasp that pretty well.  That's all, not meaning to make a big deal out of it. quote:Hilariously enough the people I've seen with the best fraction-based math are potheads.

All of this could be solved by moving to the metric system.

I think his question is why doesn't anyone say 6.8 cal, not why aren't there any 6.8mm rounds, which of course there are. Caliber doesn't mean just parts of an inch. 6.8mm is a caliber. 8.8cm is a caliber. I think the reason people don't attach it to stuff like 9mm and the like, is the potential for confusion. Most people only think of caliber as parts of an inch, even if it's not. So saying 9mm cal or 9 cal is going to throw people off, plus it's a bit awkward. Most people know 9mm is a type of ammo, anyway, so there really isn't any need.

I just spent the last week teaching every engineer under 30 what a "kilopond" was. Megajoules and kilowatthours are currently in a life and death struggle which threatens to consume us all. We're currently sourcing totally new items in inches, revealing that our originals were, too--just relabled in millimeters. The gram-centimeter-second system has taken all of our physicists hostage and has yet to issue demands. "Meters of water column" are used almost universally in conversation, but occur almost nowhere in the documentation.

Groda posted:2/3 of my company is spec'd in bar, the other 1/3 in MPa. Wow, suddenly it makes sense why my college physics teacher taught us all of the older measurement systems that I thought died off years ago. It made sense when my high school auto shop teacher taught both because we used both for certain things, but I just assumed the sciences switched over to the metric. Well, we did lose a space probe that one year because the engineers mixed up the units. My story about the metric system is that when I started school in the later 1980s they only taught us the metric system because it was believed we would be switching over soon. My dad always yelled at me when we were working on a project because I would estimate using centimeters instead of inches and that I didn't know how to read an inch ruler. To contribute, someone thinks a sporterized Krag from 1903 should be worth the same as an original condition one. http://www.gunbroker.com/Auction/Vi...?Item=174980107

There's also the one that was told on Big Bang Theory, that I felt fantastically for having heard many years before: A farmer has a bunch of chickens. They gradually stop laying eggs, and he can't figure out why. He tries everything, diet, more room, more sun, etc, but nothing works. He figures he'll ask the smartest guy he knows, a physicist. The physicist comes out, wanders around for a while looking at stuff and leaves. The farmer gets a call two weeks later from the physicist.  I've found a solution to your problem! That's great! Thank you! But it only works with spherical chickens in a vacuum.

I like turtles posted:I totally woulda been a physics major in college, but I didn't want to take the calc classes  I first wanted to go into mechanical engineering (to go along with my military MOS), but didn't get very far with math in high school. When I got into college I would have had to take four math classes to take the prerequisite science classes, just to start the engineering thing. At that point it had been two or three years since I had taken my last math class and my academic adviser suggested I take whatever their lower basic math class was. I wouldn't stand for that, wanting to pick up where I had left off (10t grade), so she put me in the next lowest. I did okay, not getting it at first, but eventually. I've always been slow at understanding math, but once I get it I'm great at it. I took the next class after that, and again, passed, but didn't do the best. It didn't help that I went on my first date on the eve of the first exam that semester. I totally forgot about it and got a D on the test. After that semester, when I wanted to sign up for the next math class my adviser said math might not be my thing. I then became an English major, since I was awesome at writing in my English classes. My main goal in life was to become an Army officer and I figured my backup plan could be to become a newspaper writer. I graduated, went to OCS, and then the civilian nurses said my blood pressure was too high. Despite another doctor showing them otherwise I was not allowed to proceed. I also applied for some newspaper jobs but never got any calls. I tried to get some before graduating but was told I didn't have enough experience after the interviews. Then the newspaper laid off most of its employees a few months later. Needless to say, life doesn't always turn out as you'd hope.
