Every customer used their own numerals as well.

He seemed to think I didn't understand the concept of a base 8 number system, and thought it was hillarious. I don't think any of us knew his name, but after I declared him Hans Moleman for obvious reasons, it stuck.

See: burger king 1/3 pounder failed because people thought it was smaller than McDonald's 1/4 pounder. Also: As I stated in the post you quoted, I was referring to a world without widespread literacy not one where the vast majority of the population not only can read numbers but also works with decimal cash math on a daily basis. When you're literally uneducated and thus unable to write a number down much less do long division to get exact decimal measures, you can still do a lot with fractions. Or, probably stated more accurately, the concept of fractions, since the hypothetical ancient people we're referring to here couldn't read a fraction any more than they could read a decimal. As someone pointed out on the last page, if you have a single reference piece of material, you can literally just use a string to get what a half, quarter, third, or really any fractional measurement of that is, take it over and cut a piece of wood close enough to build an ancient house with.

So this is from a ways back, but can someone who is a woodworking type give me a clue about tip number 5 at 1:05? Approaching cutting from my kitchen experience: a sharp knife is a safe knife. Does that not hold for sawblades? Or is it more a joke about how there's sawdust all over his saw table and poo poo?

zedprime posted:1/4 is one significant digit and 0.25 is two so I'd call them different precision. You're doing a terrible job of explaining this (and I have no idea where the hell you were going with the base-4 bit), but I think I get what you're going for. In a pure-math sense, no, fractions don't have significant figures. In a measuring-things sense, they definitely do. 1/4 = 1000/4000, nobody's going to argue with that, but if you measure something to one part in four, it's going to be read as less precise than if you measure it to 1000 parts in 4000. This is actually more obvious if the numbers aren't quite equal; a quantity that measures, say, 998/4000 on the second instrument will still measure 1/4 on the first. With that said, no, 1/4 is not less precise than 0.25, because you can't write 1/4 in decimal with fewer than two significant digits.

I believe they were called “whistle dogs” but they were regular size and not footlongs, and they haven’t been on the menu in a long time. Man I remember when A&Ws were drive in where you could get a carton (yes, carton, like milk) of root beer to take home. And the trays would attach to your window.

Probably not helped by the fact that our brains unconsciously go "well I don't SEE any danger, should be fine" My favorite time I observed this was at a waterpark, when the kids wading pool was closed because the employees were walking through with rubber boots fishing a turd out, and then using a chemical shock. Several people ignored the CLOSED signs and ropes and waded through it, rather than walk the extra 50 feet to go around.
