Why aren't you using a sliderule? You know calculators

Why don't you just memorize your constants and lectures like a normal person. Fucking writing and tools are making the youth mentally weak these days.

>>8442703
I don't care about being really good at mental math.

>>8442705
Kids these days can't even triple integrate on paper, let alone in their head

This generation needs all the help it can get

implying anyone can triple integrate on paper

>needing to actually calculate numbers
if you have a real job you work with manipulations of functions and expressions and never have to even touch the underlying numbers

He doesn't even derive his constants every time he needs them

Stay pleb :^)

I have a slide rule, a soroban, and a compass kit. I intend to become proficient with each tool, but it's a back-burner meme-activity.

Oh. Then please explain how sliderulers work?

>>8443135
You multiply by summing on logarithmic scales. Division is the same in reverse.

So, during a test, you bring out a pendulum and a chronometer to measure the gravitational constant?

>>8444634
Of course, how else could I be sure. Memorization is for sheeple like you that take things at face value

>>8444634
Obviously, there's variation in the local acceleration of gravity.
