New notebook difficulty

[michaelJwilson]

@eyu22, if you get the chance, can you take a look at the new
Dr Harvey Washington Banks notebook here:

https://mybinder.org/v2/gh/michaelJwilson/desihigh/master

In particular, how difficult you find the section on Jahmour
Givan's work. If you can!

I haven't forgotten about letting you know the dates of the
other science festivals in April. Hope you're doing well.

Apologies for the late response, but the new notebook about Dr. Harvey Washington Banks is fascinating! Especially how much his work applies to current research like DESI! 

I just have a quick question about what a "tidal force" is. Is it the same as the gravitational force? Also, just to clarify, when the notebook says  < deltaM >  represents the "average deltaM over all volumes", does this refer to all volumes in the entire universe? In this case, could you say that < deltaM > represents the average overdensity of mass in the entire universe?

This is a very minor thing, but for all the graphs, would it be possible to draw the lines thicker/bolder? It was a little difficult to make out the different colored lines for each model universe.

Everything else is explained really well! Introducing the galaxy cluster equation by first talking about polynomials and relating it to stuff most high school students already know is a clever way of making it less intimidating!

Thanks, and I hope all is well!

Hi @michaelJwilson,
I hope everything is going well! I just wanted to check in about the upcoming science festivals that you mentioned earlier. I'm sure you've been busy, so there's no rush at all to respond, but let me know if there's anything I can help with in the meantime!

Morning @eyu22, good to hear from you and I hope things are going well! Glad to hear you liked the notebook and apologies I didn't reply earlier.

We have an event both this and next Saturday:
https://cambridgesciencefestival.org/2021liveevents/desi-high-school-of-the-dark-universe/
https://ncsciencefestival.org/events/desi-high-school-dark-universe

You're more than welcome to join either! If you'd rather join as an 'instructor' than student, there'd need to be some coordination on slack in the dedicated channels #cambridge-fest #carolina-fest. Entirely up to you.

@jgivans, when you get a chance can you take a look at this? We also need to include the box fitting. Could you make a PR that changes the Washington Banks notebook directly. I think this may previously have gone into the sandbox.

Thanks for the info @michaelJwilson ! It might be best for me to join both festivals as a student, but I’m happy to help with preparations if needed. I’d also be open to saying a few words about my own experience working on DESI High as a high school student and/or how I got my school club involved. Let me know what you think!
