When The outside source is the bottom of a garbage can that stop your inertia I agreeš

What I learned the hard way was that some instructions are critical. Take the warning to close the top of your wheeled garbage can before moving it. You know the big ones that are tapered up and get bigger at the top? The lid is so big if you donāt close the lid first and you go to push the can the lid is so big it drags on the ground. At this point you will step on said lid while pushing. This will stop all forwards momentum of the can but your inertia will keep you going and thereās only one place your heading! On a side note they aināt easy to get out of when your face is smashed into the bottom and your shoulders are wedged against the sides. Seriously who designed these things?!

My father learned the hard way that it's not a good idea to climb into one of those containers. He did so to stomp the contents down. It rolled. He fell. His back broke. He went to the hospital.

if you lend a "friend" some money and never see them again, consider it money well spent!

If you want to do the math, don't forget that work = Kinetic Energy, which in turn is the integral of momentum. Mass times velocity is momentum, but the Work is KE, which is one half mass times velocity squared. When you integrate, don't forget to add + C.Lol. I hate it when I take out the garbage and suddenly become a physics experiment.

It is a whole new world to explore. Math is pure logic. The purpose of math is to quantify science. The integral of something is the area under the curve of something. Circumference is pi times diameter, which is pi times 2 x the radius. The area of the circle is the area contained by the circumference. The integral of kx is equal to one half k times x to the n+1 power, divided by n+1. Any 1/2 kx squared is the integral of kx. So, pi times 2 times r is the circumference, and the area is the integral of that, which is pi times r squared, because the 2 in the numerator and the denominator cancel each other out when you integrate.

I've known that for decades!

im waiting till they make it as fast as todays i7s

Definitely a good idea. I keep a full First-Aid kit in my Workbag. When not by my side at work, my bag lives in my car.

Handling a 2 liter bottle of pop while you're barefoot is a bad idea

Don't store packets of condiments in a bag that might get squished. :shakehead

They taste good in chinese food though

I recently bought a light that requires a 21700 cell. It didn't come with one so I borrowed the Fenix-branded 21700 from my trusty PD-36R and it didn't fit lengthwise in the new light. I checked the label on the cell and it said 21700, So I looked up the specs for a 21700 and fount that it's supposed to be 70mm long, however the Fenix cell comes in at 75mm. So I ordered an actual 21700 for my new light.

The Fenix-branded cell is beefy and lasts for a long time, however I now recall that the vendor mentioned that they were non-standard-ish. Now I know that it's the length. This should really be called a 21750 battery.

On a very similar note, I also learned that flabby wheels are VERY demanding to pedal on. Always check your tires' pressure before leaving home, guys.

Apparently it is possible to take in too much dietary fiber at a meal. Still paying the price two days later.
