FINALLY! Somebody says "the following speaker needs no introduction" and then ACTUALLY gives no introduction. Too often do people say "this person needs no introduction" and then proceed to talk at length about them. I can't stand it.
You should call a show "Matt talks about his thing" and talk about Parker square... you could end the show with: "It's probably not what you were hoping for, but at least you gave it a go." :)
yes please , that would be the most epic joke any mathematician would have ever pulled off~ ( if he can manage to not make it a Parker Square as well xD)
great work Matt , hope you give the _Magic Pentagon_ a go as well (for 'Parker Pentagon' is an alliteration I would love to spam in the comments section~)
It seems like everyone else has jumped on the "Parker square" band wagon, but I honestly feel really bad about it. Glad you're being a good sport. I know this apology might not mean much, but at least I gave it a go.
My Parker Square shirt is very comfy and I love it, thank you. Also a super great mathematical conversation starter. The shirt is not a Parker Square, despite having one on it.
It might be interesting to run other variations through the code. Basically you're looking for n(1,1), n(1,2)... n(3,3) so that n and f(n) both form magic squares. To give it a chance to work, it is best to make f(n) much smaller than n, but to stop there from being obvious patterns you should also make it move about pseudorandomly as n increases. Case in video: f(n) = number of letters in n Other possibly interesting f(n): f(n) = number of factors of n f(n) = number of symbols in Roman numeral representation of n f(n) = number of digit 1's of n when written in binary
Hey Matt, I was intrigued by this talk, and I thought it would be a good fit for a coding exercise to do in Clojure (which I'm in the middle of learning). I wrote some code to look for 3x3 squares with the added constraint of the letter counts, and I got the same results! I found the same seven squares as the ones listed in the video description. (I'd be happy to share the Clojure code with you if you're interested.) I did notice, though, that there is an error in the slides you were presenting in the video. The second set of squares you found, the ones that sum to 162 and 165, have incorrect numbers in the top left corner on the slides. The video description has 44 and 45 in those spots (which is correct), whereas the slides have 47 and 48 in those spots (incorrect). See 4:20 in the video for the slide I am referring to. Cheers!
@6:10 Did someone else noticed that extremely fixed 8 under eighteen at the top-right corner of the square? And then later turned into a 7, as I reckon, this is Illuminati. Thanks Matt for another great mathematical video!
It is good editing. If you view the video large you can see it's *very slightly* different shade of blue and different stroke thickness, and doesn't quite move with the camera wobble, but it's very tricky to spot. The best way to see it's been done is to look at 5:55, just before the camera angle changes, because the numbers slide down and you can see the '7' slide down to behind the patch-over '8'.
SHA-1 is no longer secure when it comes to collision resistance, but the preimage security (resistance to reversing the hash) is still very much secure. The people who claimed they could reverse the hash didn't know what they were talking about. Still, SHA-1 is depreciated so don't use it for anything serious :D
k a prou heard wrong. He pranked his readers with the Everything formula in his book. He may or may not have Parker Squared the "sausage collapse". I suspect that was a prank as well.
I created a magic square that has the same amount of LETTERS every row, column and diagonal, not the value of the numbers: Top left corner is 3, Top right corner is 4, Bottom left corner is 9, Bottom right corner is 2, Top edge is 1, Left edge is 6, Right edge is 7, Bottom edge is 8, and Center/Centre is 5
with other things like this hes done its fine either way as long as your consistent (cant have an AND in 1 number and not another) and state which method you used before hand
If we are going to be super strict, when *and* is used in the name of a number, that *and* actually means it is a decimal point and anything following is then supposed to be followed by whatever 10 to the nth denominator (so long as n is equal to or greater than 1). So we have One Hundered Eleven as 111, but if you say One Hundered and Eleven, the assumption is that you mean 100.11 which is One Hundred and Eleven One Hundreths. But that's when you're being super strict about how you use your mathematical terminology.
Hey standupmaths! I've generated the full list of letterwise magic squares up to 1000 (there are 1843 of them, if you're interested). I've emailed you a full list of them, with some analysis.
The video from the man who needs no introduction needs no clarification :p Nah but check out the parker square video if you hadn't already, and probably the four has four letters video which will explain the English part
FINALLY! Somebody says "the following speaker needs no introduction" and then ACTUALLY gives no introduction. Too often do people say "this person needs no introduction" and then proceed to talk at length about them. I can't stand it.
this man needs no introduction you all know him as ...
at that point id just rather say "the man the myth the legend (so and so)" and get it over with
Well done matt! A "not a parker square" parker square. Very nice properties
matt is just trying to get us to forget the parker square by showing us this new square he found. wont work
+UbererSK I don't know what you're talking about.
standupmaths your attempt at making us forget about the parker square is just a parker square
His attempt is a parker square
Makes sense. He's trying to get us to forget the parker square by mentioning the parker square.
Hey Matt! You know I just devised a name for that square thingy right to the left of your comment with your very face stuck in it. You wanna know?
Maths is fun. Keep doing maths.
Ahhhhhh the good ol' Squarker Pare
So no more jokes about parker squares? Or will this video be a parker square of an attempt to put an end to parker square jokes?
Riccardo Olivieri that was a Parker square comment, since I will never forget the Parker square
If someone discovers another 2-digit letterwise perfect square, that would be a Parker Square.
You should call a show "Matt talks about his thing" and talk about Parker square... you could end the show with: "It's probably not what you were hoping for, but at least you gave it a go." :)
no.
Yes
yes please , that would be the most epic joke any mathematician would have ever pulled off~
( if he can manage to not make it a Parker Square as well xD)
So the Parker Square has come full circle. So can we assume that a Parker Circle is when you finally get something right?
That's Numberwang!
N++ fan?
Probably a 'That Mitchell & Webb Look' fan, which is where Numberwang! originated, N++ just payed homage to it in their settings menu.
Oh, I didn't know that, thanks!
I love Matt talking about things ;)
I love Matt talking about his thing . . . . the Parker Square of course~
You may find interesting stuff with the 3digit numbers because if you add 100 to every numbers , you get a working magic square.
great work Matt , hope you give the _Magic Pentagon_ a go as well
(for 'Parker Pentagon' is an alliteration I would love to spam in the comments section~)
It seems like everyone else has jumped on the "Parker square" band wagon, but I honestly feel really bad about it. Glad you're being a good sport.
I know this apology might not mean much, but at least I gave it a go.
You're not even sorry. What a Parker square of an apology.
LOL brilliant
I'd love to see a longer video on this.
Glad to see this video. I found the shirt on teespring and it has 2 days left.
I was going to make a parker square joke, but it's not any fun when it's already on the video, c'mon ...
You wanted to do it but just didn't go through wi¸th it
+David Melo At least you gave it a go.
one might call this a parker square of an attempt at making a parker square joke
So it's a Parker Square Squared
Matt Parker just Parker squared the Parker square joke maker, get Parker squa-rekt?
My Parker Square shirt is very comfy and I love it, thank you.
Also a super great mathematical conversation starter.
The shirt is not a Parker Square, despite having one on it.

Love it!
Gave it a go and won!
Looks like a good exercise for my exam...
We are learning to code in python in one of the courses this year.
:)
Lee Sallows created an alpha geometric magic square from that last square. It is #18 in his geomagic squares gallery on his geomagic squares website.
I usually don't call it a parker square.
I call it a car park.
Would've been better if you wrote parking lot instead :D
Is not a parking lot a group of car parks ?
That's lots of cars parked , that's what it is~
A parking lot is a group of parking spots.
Beautiful
Good work, Matt. I like it.
Great maths jam video

Thanks Matt for another great mathematical video!
+John Lindstedt Yes, that was me fixing a typo in the presentation!
I can´t see it.
Lol, it's really there. Good editing skills!

The best way to see it's been done is to look at 5:55, just before the camera angle changes, because the numbers slide down and you can see the '7' slide down to behind the patch-over '8'.
In the last slide (at 6:00), the seven on the top right of the square was switched to an eight actually. Interestingly somehow stabilized. :)
SHA-1 is no longer secure when it comes to collision resistance, but the preimage security (resistance to reversing the hash) is still very much secure. The people who claimed they could reverse the hash didn't know what they were talking about. Still, SHA-1 is depreciated so don't use it for anything serious :D
Love that you use Python all the time. :)
Don't worry about the Parker square, focus on the Parker number:905;2580,1730
Wished I was there!
This video was the Parker Square of trying to fit your talk within a 5 minute time limit ;)
(I saw those extra 15 seconds)
You're awesome!
It'd be hilarious if you Parker-squared the hashes, since no one would notice. I heard you Parker-squared the 'Everything' formula in your book!
k a prou heard wrong. He pranked his readers with the Everything formula in his book. He may or may not have Parker Squared the "sausage collapse". I suspect that was a prank as well.
guess the language, the amount of letters 1-10:
1=2
2=3
3=3
4=6
5=4
6=4
7=4
8=3
9=3
10=3
Hi standupmaths
+JBCuber Hi JBCuber
Well this is the shortest lecture I've ever seen in my whole entire life O__O
Ooooooh! 16 seconds over the limit!
According to legend, King Mi, a 5th century Northumbrian monarch, found the last square written in runes on the bole of a sacred yew tree.
I created a magic square that has the same amount of LETTERS every row, column and diagonal, not the value of the numbers:
Top left corner is 3,
Top right corner is 4,
Bottom left corner is 9,
Bottom right corner is 2,
Top edge is 1,
Left edge is 6,
Right edge is 7,
Bottom edge is 8,
and Center/Centre is 5
when there be a next video on the four has four letters video?
How perfect that the video is a square number in length! 25^2
Only if you count 6:00 as 600. 3625, the number of seconds, would not be a square.
That's a super-Parker square!
If you add for example one hundred to every number in the square, you will get another magic square that will work, right?
This doesn't redeem you from the Parker Square
you should talk about 4, the "cosmic number"
never mind, you already have. i figured you had, but couldn't find it.
If you missed one, this whole presentation would have been a bit of a Parker Square
that's the most brilliant utterly useless thing I've ever seen. I love it
that's what everyone thinks about the 'Knot Theory' as well , I wonder why~
First comment in 3 years. So, did anyone verify your result, +Matt Parker?
For the three-digit version, would you be using "ONE HUNDRED ELEVEN" or "ONE HUNDRED AND ELEVEN" for 111?
Phil Boswell He said the english version so I guess not the american version
Eleventy one!
with other things like this hes done its fine either way as long as your consistent (cant have an AND in 1 number and not another) and state which method you used before hand

really? when we talk about decimals we have a rule where each digit must be said separately, i.e: 2.7685 would be two point seven six eight five
I've just found out, that there is a wikipedia article about Parker square.
Liar. You got me to check, though. Good for you.
da Sharpman There is. Or at least was. Every now and then it pops up just to be taken down. Kind of a
Parker Square if you ask me..
NitNat6781 Heh.
Cool
I'm curious how it works in other languages. I have to try it in french at least :)
Hey matt, you talked about the pyhton code for the squares? can you make it available ?
when are you going to upload the square triangle number video?
Successfully finding a magic square is the Parker Square of trying to get a Parker Square.
Yo!
+RussDragon Yo!
Yo！
Hey standupmaths! I've generated the full list of letterwise magic squares up to 1000 (there are 1843 of them, if you're interested). I've emailed you a full list of them, with some analysis.
I thought this was a bit of a Parker Square. LOL😃
Be my mom
You went 15 seconds over
time traveled 15 seconds too fast
What a Parker move.
Aidan Christensen A Parker Square of a presentation, if I do say so myself XD
Is this a Parker square
hi
I'm disappointed this talk wasn't about actual parker squares.
ayyyy 301 club and 13th comment.
how many empty computer files would it take to fill the memory of the average computer memory
Is it possible to make a magic rectangle?
How about a magic hypercube instead?
To be fair... Please, make a claryfying video about the subject.
The video from the man who needs no introduction needs no clarification :p
Nah but check out the parker square video if you hadn't already, and probably the four has four letters video which will explain the English part
Parker Square?
More like Parker², amirite?
Under 301 club im s o gud.
under 324 club.
You beat me to the club. Gonna beat ya with a club!!
the 301 club is harder to get as it doesnt pause on 301 anymore
second comment!
5 minutes only?! So disappointed at this event
Did you ever take a public speaking class?
first comment
harshit gakhar second
+harshit gakhar Can confirm: first comment.
Dammit , I didn't know you get a reply from Matt Parker if you're the first one to comment~
Rew Rose ikr I was so close (at least Matt replied right below my comment)
Wumbolo
it's just his Parker Square attempt at replying to you~
the video is *6:25* long. :D ;)
Just because 625 is 5^4?
Franz Schubert No, because it is 25 "squared" and they are kinda talking about squares only
Five squared squared
Had it been 6:24 we could have said it was 25 "parker squared"
Ameto yeah😂😂
zero view club
Wumbolo yeah me too👍
