Yeah, I know the audio is messed up. It's not the mic, it's because I recorded via OBS, and that messed up the audio. Sometimes it's difficult to get all the tech working. I tried.
If the audio is really hurting your ears, I process the audio a bit and made an unlisted version of this video with different audio • Follow-up Birthday Mag...
At 2:20 I point at a group of four and say it adds to 43. That was a mistake.
At 27:40 I said April but typed in 03. Whoops.

Here is my excel spreadsheet for creating birthday magic squares

And I forgot to say that Christian is occasionally available to make things like this for commission.

Lovely to get a shout-out. You are totally right, it is all about curiosity and having fun with math. All the other stuff, where you learn its usefulness comes so much easier if you are enjoying it and having fun with it.
I know the audio is mess up. OBS did that for some reason. It's hard making all the tech work. I tried, and it didn't.

Legend says that magicians were the second people to discover the Euler Square, which is why we now call them Magic Squares. ;D
This free flowing follow-up video with all the extra stuff you want to mention is a great idea
"How incurious would you be if you didn't make one for yourself"
Way to call me out there, James! OK I guess I'll make one now.
I hope you're still making videos. I saw your video on the Mills constant which was really great. I'd thought I'd draw your attention to new research about this. Simon Plouffe has a new (well, 2022) paper out revisiting Mills and Wright. He produces some new formulae, and discusses the order of growth of the Mills constant functions, and creates some new constants and prime generating functions with slower growth rates. You should really check it out! I believe he set some records for the longest prime generating polynomial in the paper. The paper is titled "A set of Formula for Primes" and is on the Arxiv. By the way, if you aren't familiar with Simon Plouffe, he's one of the co creators of the Bailey-Borwein-Plouffe formula (BBP formula) , which is is an explicit formula for the digits of Pi. The paper is fantastic and is really worth a look, I'm sure you'll enjoy it (and I hope you'll make a video about it!).
I watch you in numberphile! Happy to finally find your channel!!
I really love your videos!! I've always been told I'm good at math but I just find it really interesting. I hope you keep making videos. I'll make sure to stop by and watch when you do!!
I didn't tell you that I made a spreadsheet template for playing with magic squares--I was afraid you would say I was cheating by not using pen and paper. Glad to see you avail yourself of tech options occasionally, too. Thanks for the shout out--practice toward my nerdy birthday gift for my sister is going well!
James, i always enjoy your videos, not only because of the content but also because of your kindness and enthusiasm.
fascinating stuff... but i cant help but wonder... because the discovery that april is the third month of the year has stunned me a bit ;)
From 5 minutes of showing off 5x5 magic square years ago to almost 1 hour explaining magic square methods! Love all of in-depth explanation of the squares. I thought you'll go into another dimension from the length of the video (3D magic cube? Sounds interesting)
Now I'll go into rabbit hole of some random knowledge in the depth of Wikipedia.
I was hoping for "if you have been, thanks for watching." It's such a good ending that I don't see why it couldn't end these follow-up videos as well. Especially for people who've made it to the end of a video > 56 minutes long....
Appreciate the time you put into this, very interesting!
I'm wondering why the Euler square doesn't work for 6 by 6.
About the last one: I think the 6x6 was proven exhaustively.
👍
Thank you ❤
Thanks for the shout-out.
I'll be sure to go give them some views. I'm very interested in adding secret-sharing into locksport as demonstration of master keyed systems. (And the weaknesses of mechanical systems that leak information.)
I have in mind a cross lock or adding a second bible to a KIK cylinder but splitting the keys such that any pair could be assembled into a working key.
Well done for making it to the end!
This channel deserves more attention.
You're very interesting and the content is pure!
Can you revisit Conways Game of Life. Can you do a video about how sudoko boards are manufactured, specially the ones that have symmetry.
A video on Gurth's Theorem would be amazing.
Hi! Very cool channel! Like 👍A big hello from Italy 🥰
@singingbanana. Hello, Dr. Grime. May I call you James? I'm an ex-math teacher, and I want to start sharing math surprises on RUclips like you. I lack experience creating content on RUclips. My 1st recording was 55 mins long, but I have not edited or uploaded it yet. The content is an improvement on a ScamSchool trick. You would probably present the trick and maths better than I. Would it be a problem if I sent you my video to take a look at. I'm not sure how to send you a message properly. By the way, I did not realize you knew Brian Brushwood. You are both inspirations to me.
No problem. You can contact me via my website. I will see it.
thank god it's not Parker square!
I'm fine with the "just talking to the webcam" videos, but the audio here is kinda weird, like maybe you're blowing out your mic. It sounds almost like it's not being recorded from your lavaliere mic at all.
It's something to do with OBS. I couldn't figure out what the problem was.
now waiting for "parker magic square" to pop up - I know he is watching
not gonna lie, i was considering to add a birthday square function to my own magic square generator. might still do that anyway...
Today I learned that my magic number is my birth month squared so I have a magic square that's equal to a square number. I'm sure that must be some lucky omen :P
Just-talking-into-the-webcam-videos are the best videos.
I made this comment on the first video, but I'll share it again here in case you didn't see it.
So it looks to me like if you want to do this on the fly in front of people, without any repeated values, then instead of filling in all of the squares by letters, fill them in by number first. This way you can double check as you do it to make sure that you're not repeating any values. As a starting point, make sure that none of the 4 numbers you are adding are the same as the differences between any of the two numbers in the top row. If you like, you can even use negative numbers.
The only problem with doing birthdays though, is that some people will have repeated numbers in their birthday, like March 03, for example. To avoid this, maybe just ask someone to give you four different numbers.
I enjoyed that Euler's birthday sum was 43 and mine's 143. Pure coincidence, but hey.
Some matrix element groups do not adhere to DD MM CC YY semantics in all directions (like there is no 18th month). Perhaps in one direction or starting form a certain element or at least one permitation...
Hey, I can’t get this off my mind. There is this problem I’ve been thinking about that involves a 4 digit combination lock. Like everyone who has ever used this type of lock they scramble all the numbers after locking it back up. What if every night I was lazy and only changed 1 (or 2, or 3) of the numbers on the lock. Is there a way to figure out my combination if a thief went to my lock after every scramble and collected data of what numbers were on my lock. Could he ever be 100% certain after a long period of time? Not sure how to even attempt solving this. I’d love to hear from anyone that know anything about this.
Hey , can you make a vedio on collatz conjecture
@26:15 Magic Square
16 12 20 21
13 28 06 22
23 25 10 11
17 04 33 15
2:22 Did I forget how to add or doesn't that top-center square add to 41?
Correct. My mistake.
2:20, 4+17+6+14=41, so that doesn't work?
He's acknowledged that- it was a mistake.
Hey, if your birthday total is below 34, don't be upset! That makes part of only 2.5% this century! (Estimated a normal distribution of births this century)
Edit: wait, this is too much, I can't do math. it's 0.8%
First. Yay.
Webcam audio is not great.
