QUEER BOOK CLUB TIME: The Lady's Guide to Celestial Mechanics by Olivia Waite

Hello there, everyone! This month's book was The Lady's Guide to Celestial Mechanics by Olivia Waite, and what a way to kick things off for our first book club! This book had a lot of things to say about ... well, a lot of things. So, let's get right to it, shall we?

In short: What did you think of the book?

  1. How did you find the progression of Catherine and Lucy's relationship?
  2. The book says a lot of things about science and art and the comparison between the two. How much of it all did you agree or disagree with? Is artistry about the process or the product? How much of science should be credited to inspiration?
  3. Both Lucy and Catherine are being held back from being granted titles they wish - and deserve - to have. How did you feel about the journeys they both go on before being granted these titles?
  4. Favorite moments and quotes?
  5. Will you continue reading series? To people who have read the second book, how does it compare to this book?

And, of course, absolutely anything else you'd like to talk about.

Look for our post tomorrow regarding nominations for the book we will be reading in May.

(No spoilers) "Celestial Command" A little Indie game which may scratch that Expanse space itch you have: orbital mechanics, mining, trading and combat. (Warning still in alpha and development)

As the title says it is still in alpha and you should read up and watch some gameplay before you try it, but i simply love the orbital mechanics and the freedom of movement

Enjoy!

Halfway Check In: The Lady’s Guide to Celestial Mechanics by Olivia Waite

Hello, lovely people! This month’s Queer Book Club book is of course The Lady’s Guide to Celestial Mechanics by Olivia Waite. We have ten days left until our big discussion of the book, so save all your spoiler-iest insights and harangues for then.

However, as a brief respite to those weighed down with thoughts about this book, I offer you this post with the general overarching discussion question of: how are you enjoying the book so far?

Potential further questions:

  • What (if anything) had you heard about The Lady’s Guide and how did that color your expectations for this book? How is the book matching up to your expectations?
  • What are your first impressions of Lucy and Catherine?
  • How do you feel about regency settings? How does Waite’s setting hold up to others?
  • Anything else you’d like to talk about?

Finally, if spoiler-y type things are going to be mentioned, please use spoiler tags.

The final, spoiler filled, no holds barred discussion will be held on the 30th of April.

Celestial and orbital mechanics

Hi!

quick question, what area of study do we study celestial and orbital mechanics under. Is it physics, astrophysics, aeronautical engineering, or astrodynamics? Basically what major focuses on these topics?

potential exploitation of celestial bonze mechanic?

celestial bronze passes through normal people like they are not there.

Could with some exploitation or if some alien scientist put some time into changing the fabric of reality someone create an armor or shield that treats ALL attacks both metaphorical and physical as celestial bronze for a normal person?

Something like zeus’s thunderbolt passing right through someone, who then proceeds to knock him out with a single punch.

But really, if a bunch of people believing about something causes it to exist, why could a army of AI or a super sun sized computer simply warp reality directly? Such as time travel, or changing logic.

Celestial Empire Mechanics (CK2)

So, after reading the lore diaries about it I decided to start up a game playing as emperor. At first I was quite confused about the different mechanics.

So far I have loosely got to grips with them, but I’m still not totally sure what imperial power (or influence or whatever it’s called) does. On my first character I had various strong/weak/figurehead emperor traits, but after that they never happened again. Is that all imperial power is used for? Getting those traits that never appeared again?

And the bureaucracy one - I get that if you get over 40% (or whatever it is) you lose the inefficient bureaucracy modifier, but is there any other reason to peruse it? Because I think the highest I’ve managed to get it so far is 45%.

Why would I ever influence court? I get that I can try and persuade a character to be a friend (although I only tried that once and it failed....) but what else does it do?

Finally - what does a Governatus do? And why should I appoint one when I can just not have one?

Thanks a bunch, these questions have bothered me!

Book Club Discussion: The Lady's Guide to Celestial Mechanics by Olivia Waite!

Happy Saturday! It is beautiful and crisp and I can almost taste autumn where I live today. I hope everyone else is having a nice morning. Today's book club is about The Lady's Guide to Celestial Mechanics by Olivia Waite. A lovely historical lesbian romance with a science lady and an arts lady.

Not sure what this is all about? Link to Book Club Info & FAQ post

A note about spoilers: This thread is to be considered a spoiler-happy zone. If you haven't read the book and don't want to be spoiled, this is your warning. Even my questions below will include spoilers. I'm not requiring anyone to use the spoiler codes. Feel free to discuss the very last page of the book without worrying about it. If you haven't read or finished the book and you don't care about spoilers, you are of course still very welcome.

Who got to read the book? What did you think?

Here are some questions to get us started. As always, this is not required- talk about any of these topics, all of them, or none.

  1. First, as always, what did you rate the book? If you do star ratings or something, feel free to explain how they work.
  2. I don't want to make it too leading of a question for some of these, so here are some topics the book hit hard on that we could discuss:
    1. Contributions of women in science
    2. Gatekeeping men
    3. Men of color and women being allies
    4. Domestic arts and fiber arts - real art?
  3. Did you like the storyline of the elder women who were clearly in love, but it was presented to the world as being close friends?
  4. I saw a really good review and wanted to present this quote from Silvia on Goodreads:
    1. " And there's a lesson for histfic authors: you don't have to pretend that historical times weren't a cesspool of misogyny, homophobia and racism, but it's entirely possible to write a book for the people who have historically been hurt and marginalized that focuses on the good stuff instead of on the awful. This book is proof of that." What do you think of this?
  5. The writing in this book slayed me, y'all. Some of my highlights:
    1. "Lucy sat. Catherine took possession of the left-hand guest chair as though it were a throne."
    2. *"I am tired of twisting myself into painful shapes fo

The Lady's Guide to Celestial Mechanics is the next book club pick!

Woo!

This is a lovely historical lesbian romance, with science, math, and embroidery!

We'll discuss on Saturday 9/19. I usually post in the late morning EST, so keep an eye out. u/disastrouslyshy might post it instead, so keep an eye out for that too. It looks like it's still on sale on Amazon and Chirp, too.

As always, come armed with opinions, highlighted portions, questions, and rants/raves.

Goodreads summary:

>As Lucy Muchelney watches her ex-lover’s sham of a wedding, she wishes herself anywhere else. It isn’t until she finds a letter from the Countess of Moth, looking for someone to translate a groundbreaking French astronomy text, that she knows where to go. Showing up at the Countess’ London home, she hoped to find a challenge, not a woman who takes her breath away.
>
>Catherine St Day looks forward to a quiet widowhood once her late husband’s scientific legacy is fulfilled. She expected to hand off the translation and wash her hands of the projectβ€”instead, she is intrigued by the young woman who turns up at her door, begging to be allowed to do the work, and she agrees to let Lucy stay. But as Catherine finds herself longing for Lucy, everything she believes about herself and her life is tested.
>
>While Lucy spends her days interpreting the complicated French text, she spends her nights falling in love with the alluring Catherine. But sabotage and old wounds threaten to sever the threads that bind them. Can Lucy and Catherine find the strength to stay together or are they doomed to be star-crossed lovers?

Questions about Celestial Empire mechanics

I've been playing this mod for a while now and have mostly stuck to the East Coast and Latin America. I decided to take a stab at the Celestial Emperor Elton. However I'm completely lost. How do I view how high imperial authority is? How do I lose the figurehead trait? I really really like the lore behind the region but I'm just a little confused by some of the mechanics at play.

Any astronomers/physicists out there familiar with celestial mechanics willing to help consult on an animated short film project?

Hello Astronomy/Physics nerds!

I'm working on a short animated film, and there's a moment in the story involving some celestial/orbital mechanics that I'd love to get as "accurate" as possible (I put accurate in quotes, because it takes place in a fantastical universe of tiny planets, a la The Little Prince). I went to film school and have very little knowledge of astronomy, physics, or how orbits work mathematically, but I'd like the character in the film to at least LOOK like he knows what he's talking about. That's where, hopefully, you come in :)

Basically, there is a moment in the film, in a fictional solar system, where a character on one planet wants to predict where another planet will be at a certain time in its orbit, so he can launch himself from his planet to the other.

We see him first using a telescope to take measurements of where the other planet is from his vantage point, and then later we see his "lab" where a chalkboard is filled with the math he would use to figure out the other planet's orbit, and to figure out when and with what sort of direction and force he should propel himself to get to the other planet. So, I'm looking for help designing his process and the props you'd see as a viewer for these two moments. Specically, I'm hoping to answer these questions:

    1. What would the notes in his notebook look like as he records the other planets movement with his telescope? What sorts of data would he need to determine it's orbit in relation to his planet's orbit?
    1. What would his diagrams and equations look like on a chalkboard to figure out where the other planet will be in the future?
    1. What would the equations look like to figure out how much force and what direction he would need to "take off" from his planet to get there?

I could, of course, just write a bunch of vague scribbles and generic equations and diagrams, but I'd love it if someone who cares about this stuff notices the details as accurate because I love that kind of attention to detail in movies :)

If you're interested in seeing progress on the film, you can check out our instagram , where my wife and I are documenting the process of building miniature planets for use as stop motion sets, with 2D animated characters. It's a really fun passion project that we've been spending our night
