Thank you. This project has been knocking around for a year now, so a few extra weeks won't hurt

Recording 25 on calculating the parabolic trajectory of a cannon ball, I need some help with how to read these m's:

"we are to take 1⁄m thereof, that is 1⁄mm of the impressed Force. And for a third Moment (at equal distance of time) 1⁄mmm; for a fourth 1⁄m4; and so onward infinitely."
and
the Lines of Motion (answering to those equal Times) are to be as 1⁄m, 1⁄m2, 1⁄m3, 1⁄m4,

Also

V + V⁄R + V⁄RR + V⁄R3 + &c. = VR/ R - 1
do I say "V over R", or "V divided by R"?

Thanks.

I'm sorry, I can't help... it's all gobbledygook to me

If there is no standard way of expressing them, whatever you're comfortable with. But someone with more scientific knowledge might know... Tricia? Ava?

I'd say either one - "V over R" or "V divided by R".

"are to be as 1⁄m, 1⁄m2, 1⁄m3, 1⁄m4" - these are, of course, m squared, m cubed, and m to the fourth, respectively. I'd read them as "1 over m..." but either way works.

It's another way of writing squares, cubes, etc.

So:

we are to take 1 over m thereof, that is 1 over m squared of the impressed Force. And for a third Moment (at equal distance of time) 1 over m cubed ; for a fourth 1 over m to the power of 4; and so onward infinitely."
and
the Lines of Motion (answering to those equal Times) are to be as 1 over m, 1 over m squared, 1 over m cubed, 1 over m to the power of 4,

same below:

V + V⁄R + V⁄RR + V⁄R3 + &c. = VR/ R - 1

V plus V over R plus V over R squared plus V over R cubed plus etc. is equal to V times R over R minus one.

"over" is better than "divided" when you are dealing with letters rather than numbers, especially when the letters come in squares or other functions.

Okay, I've got this one. Not sure what else I may run into but I know you've got my back! Thanks. I'll give it my best shot.

Here is chapter 19/section 21, with a runtime of 22:49

To be honest, I have seldom read anything where I did not have a clue what was going on...

(And that includes cold readings of dramatic roles)
At least, I have now learned what a syzygy is - should I ever need that again.

Please return sections 23 and 25 to the pool. For the first time ever, I am going to relinquish my sections because I cannot do them justice. I cannot even begin to do them justice. Someone with considerable mathematical/scientific understanding may be required to read these sections with any fluidity but I cannot pull it off. I am sorry. Bravo to Availle for plowing through. Good going, girl.

Thank you. So, what is it, enquiring minds want to know ?

No shame there, Michele - I couldn't even attempt them

Three celestial bodies arranged in a line.
Examples: full moon and new moon.

I'll try and work it into dinner table conversation

I'll take 25 for now. Perhaps I'll grab the other, but I don't want to overcommit.

I'm interested in tackling Chapter 23 *gulps*

I have a math expert on speed dial who has answered some of my questions and I will trust her word regarding what she thinks the symbols mean.
