Drop off before feeding time...

well, that's one way to kill a human.

Dad should have chuckled and said, "Son, only I can fuck your mother." Patted him on the head and left the room.

If you have to, use a large rock or a sharp pointy object. Amazon has a small tool you can attach to the key chain to break glass.

Problem is these are usually left in the car for breaking out a window in the event you're stuck inside after a crash. Nobody keeps these on their keychains as they're a bit bulky.

And crazy to see I paid \$25 for it back in 2012.

Nautical miles are one of the only units that don't have an arbitrary basis - it's the arc length of 1/60th of a degree on the earth's surface.

I guess this is funny if you're not good at STEM.

How is that definition not arbitrary?

what happens when the earth smooshes/stretches ever so slightly at the poles?

also, "standard" is the antithesis of arbitrary, which is why we establish actual standards. kg, for example, is absolutely not arbitrary because it has a very specific standard--literally "the kg" which exists as a singular, specific, hunk of matter (which, yes, has its own decay rate).

I can't think of a unit of measure that isn't standardized. We have an entire federal department (within a department, I think)--NISA--that qualifies standardization.

Just rerun the calculations.

NIST, IIRC.

That's literally arbitrary, as it can change based on the distance from sea level, *or* the sea level, for long-term measurement recording.

I mean, the whole metric system can be said to be 100% not arbitrary in origin

How is that definition not arbitrary?
It may seem random to you, but it's not for two reasons:
1. it's a rather exact reference unit that can be reproduced. Just like a meter is defined as "the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second."
2. arc units (minutes and seconds of arc) and degrees were the original tools of the trade for early sea navigation

1/60 of an arc second varies with latitude as the earth isn't a sphere. The actual length assigned to the nautical mile was agreed to by a committee as a compromise.
