I remember studying noticeable difference in math class. Typical lesson was something like this...
Math Teacher: "If you're carrying a backpack of rocks weighing 20kg, how much additional weight can you carry in the backpack before there is a noticeable difference?" *
Stoner behind me in class: "Dude, why would I be carrying a backpack of rocks?!?! I would rather carry snacks... like graham crackers, vanilla frosting, and chocolate. 'Cause you never know when you're gonna want s'mores!"
Math Teacher, going with the flow: "Okay. So, you're carrying 20g of snacks. How much additional SNACKAGE can you carry in the backpack before there is a noticeable difference?"
It was actually one of the coolest lessons in math. I was a brainiac in school, so I always paid attention. But this lesson got EVERYONE involved. Yep, even the stoners. I think they were trying to figure out how much weed they could keep in their lockers before the administrators caught on to them.
So... I got to thinking today about noticeable difference again. 'Cause I'm really hating my hair right now. Huh? I know. This is a huge stretch... but stick with me for a wee little bit.
Right after I get my hair cut, I usually hate it for about a week. Then I can live with it. About two weeks after the hair cut, I absolutely love it. It's perfect. Another week later... meh. It's okay. Then all of a sudden... WHAMMO! It doesn't work at all, and my bangs are hanging in my eyes. (And if anyone suggests that I grow out my bangs so I don't have to worry about this... just stop. Stop right there. I have that FOREHEAD thing. As in big forehead. A boyfriend in high school once told me that I could hang a billboard on my forehead. Yeah... he was an ass. But I never forgot it! Bangs are a must on this chick. End of argument.)
So, how can my bangs be just fine one day, and then the next... I look like Sam Sheepdog trying to keep Ralph Wolf away from the lambs??
What is the noticeable difference when it comes to the length of bangs? Lest anyone think I'm aiming for humor here (sorry Aussies... "humour"), let me assure you: I'm not. I really want to know!
*Technically, the noticeable difference for this example is 1kg.
