MPMP12: Multi-Dimensional Marching Band
This video takes a look at the 12th of Matt Parker's Maths Puzzles, the marching band puzzle. It explores a somewhat simple way to find a solution to the puzzle, as well as exploring solutions in higher dimensions.

MPMP11: Simultaneous Equation Of The Ages
มุมมอง 5674 ปีที่แล้ว
Finding a solution for Matt Parker's Maths Puzzle number 11. We work backwards through the puzzle to define the age at each point from just one particular variable, then use simultaneous equations to work out what the final age is. But then how do we know whether to consider these sorts of things puzzles or not. With just a small change, we go from 1 answer to multiple answers. This video discu...
MPMP8: Further Folding
มุมมอง 2624 ปีที่แล้ว
This video takes a further look at the original stack folding video I made. It addresses a mistake I made in the original video, as well as expanding to see what solutions are possible for larger sized layouts.

MPMP8: Folded Paper Puzzle
มุมมอง 4924 ปีที่แล้ว
In this video we take a look at the folded paper puzzle from Stand-up Maths. We take a look at how the physical properties of the folding can help us determine whether a certain order of the sheets is possible, and go on to work out what the different possible orders are for a sheet of 8 sections.

How QR Codes Are Built
มุมมอง 220K4 ปีที่แล้ว
During some coding for a uni assignment, I became interested in how QR codes are generated, and thought it would be an interesting topic for a video. The concepts that QR codes build on go way beyond the level covered in this video, but hopefully this gives a good introduction for those who are just curious.

MPMP5: All Possible Winning Solutions for Triangular Peg Solitaire
มุมมอง 1.2K4 ปีที่แล้ว
Taking on another further challenge from Matt Parker's Maths Puzzles, today we take a look at the possible winning states for triangular peg solitaire for boards of any size. The evidence for the boards beyond size 4 are based solely off simulated games, so the solutions are not guaranteed to be accurate, but they seem to fit pretty well!

MPMP4: 16 Shades of Gray
มุมมอง 4004 ปีที่แล้ว
This video takes a look at the 4th of Matt Parker's Maths Puzzles and explores the concept of Refelcted Binary Code, or Gray Code. This cycles through all possible binary values with a given number of bits by only switching 1 bit at a time. This same approach can be taken to the card puzzle posed in Matt Parker's Maths Puzzle 4.

MPMP1: Turning Tables On This Maths Puzzle
มุมมอง 6314 ปีที่แล้ว
This video differs from the previous ones, and takes a look at the first Matt Parker Maths Puzzle. It looks at the arrangement of the table that allows only 1 correct envelope-person pair for any given position of a rotating table, and has a deeper look at whether this holds up for odd and even numbers.

Here's a simple overview of how IPv4 addressing works in a class based network systems. It is intended for academic purposes only, as class based networking is very out of date.
Bellman-Ford Algorithm - Simple demonstration without negative weighted connections
มุมมอง 1.7K5 ปีที่แล้ว
This is a video giving a simple explanation and example of the Bellman-Ford algorithm for finding the best path through a network. It only demonstrates simple use of the algorithm and does not include any negatively weighted paths or loops.
Thanks for the video!

ooh boy generating these things sounds complicated as hell
Davis Betty Rodriguez Michelle Taylor Amy
@1:04 "at a size of 1 pixel." I don't think that's correct. A square can be made of many pixels, and in some cases the QR code may not even be screen-based. They exist on paper, as well.
I scanned the qr code on the preview and it's says 11216711)

Thanks for not explaining the error correction! Now I know how to not make a qr code!
It's either you skipped or can't understand it

Thank you!!!
Sometimes I make a Q R code in different ways

Hi there. This is Via. I have a paid video collab with you. Pls let me know if you have any interest. :)
Simple and amazing 😮
This was great, thank you for explaining how they are built!
Perfect!
Exactly the info I was looking for; thank you!
wow very good explanation. Finally someone REALLY showed how this works
6:06 Rick roll QR code? No, it’s you James Explains
Thanks
Hi! This video was so informative - thank you! Can you have QR Codes that look different but take you to the same location?
Thank yoy james
well explained, James 😀
I am a 13 year old who has to program a gui program in C that can create an QR code of 3 different standards. This was so helpful because I was stressing about this project so much.

It's the mark of the beast. You'll see, when the world switches to the digital dollar everyone will have to get this tattooed to buy and sell. The three squares make up the 666.
Thank you for the clear and short explanation :D
Fantastic!
Great explanation
A very good explanation!
Fabulous
Q is for Query
I tried this on my xiaomi
It works! Thank you for your help!
Thanks for the video. Bless you!
Shouldn't High be able to restore more than Quartile?
one and only easy and working method
Top of the top, great work!
Thanks! 🙂🙂🙂
So its possible to read a QR code by looking at it, if your sufficiently far on the spectrum, I bet you can read them.
fire
I don't get a QR code can hold 7000 bits but writing 2 words filled the qr code
Just as confused as when I started. Oh well.
Most of the "How QR codes work" videos are not actually how they work, but how they are used. You rang true. Excellent video!
Same. I was getting annoyed. I wanted to this THIS type of video but had to go through ten videos to get to this one.
Incredibly well explained! Thanks for sharing. 😍😃😎
It's crazy how so many people scan QR codes but no one actually knows how they work.
Exellent i learned a bit of qr code but idont know how the error correction works
Finally! I may not still understand it, but I gathered a lot more of the gist than the other 'instructional' "how do qr codes work" YT vids I watched.
This is the stuff I was looking for almost half an hour.
