Make A 9x9 Magic Square! Learn The Ancient Chinese Algorithm (Lo Shu Square)
 
09:10
Magic squares are arrangements of numbers where every row, column, and diagonal adds up to the same number. The ancient Chinese developed a geometric method to create 3x3 magic squares. Remarkably, they generalized the method to create a 9x9 magic square which is quite the feat! The Lo Shu Method From "The Evolution of Mathematics in Ancient China", Frank Swetz, Jan 1979. Appears in "Sherlock Holmes in Babylon." http://amzn.to/1c2QBSm Lo Shu Square courtesy Wikipedia http://en.wikipedia.org/wiki/File:Lo_Shu_3x3_magic_square.svg *Thanks to Patrons* Kyle Alberto Nishikawa If you like my videos, you can support me at Patreon: http://www.patreon.com/mindyourdecisions Connect on social media.

📚 Using invertible matrices with cryptograms

✔ https://StudyForce.com ✔ https://Biology-Forums.com ✔ Ask questions here: https://Biology-Forums.com/index.php?board=33.0 Follow us: ▶ Facebook: https://facebook.com/StudyForcePS/ ▶ Instagram: https://instagram.com/studyforceonline/ ▶ Twitter: https://twitter.com/studyforceps A cryptogram is a message written so that no one other than the intended recipient can understand it. To encode a message, we can begin by assigning a number to each letter in the alphabet: A = 1, B = 2, C = 3, … Z = 26, and spaces = 0. The numerical equivalent of the message is then converted into a matrix. An invertible matrix can be used to convert (encode) the message into code. The multiplicative inverse of this matrix can be used to decode the message. Q1. Use the coding matrix ... to encode the word BASE. Q2. Decode −7, 10, −53, 77. * Encoding a Word or Message 1) Express the word or message numerically. 2) List the numbers in step 1 by columns and form a square matrix. If you do not have enough numbers to form a square matrix, put zeros in any remaining spaces in the last column. 3) Select any square invertible matrix, called the coding matrix, the same size as the matrix in step 2. Multiply the coding matrix by the square matrix that expresses the message numerically. The resulting matrix is the coded matrix. 4) Use the numbers, by columns, from the coded matrix in step 3 to write the encoded message. * Decoding a Word or Message That Was Encoded 1) Find the multiplicative inverse of the coding matrix. 2) Multiply the multiplicative inverse of the coding matrix and the coded matrix. 3) Express the numbers, by columns, from the matrix in step 2 as letters.

How secure is 256 bit security?
 
05:06
Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Home page: https://www.3blue1brown.com/ Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives the desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

What's a Creel? Mathematics Challenge
 
12:57
Welcome to the most difficult Mathematics Quiz in the World – The What's a Creel? Mathematics and Computer Science Quiz! I'm not certain I could solve these riddles myself, but I certainly hope someone can! Read and agree with the terms of the disclaimer below. Be careful when you copy and paste the number marked “Cipher”. Good luck all, and may the force be with you! Disclaimer: The final determination of the winner remains absolutely in my discretion. I reserve the right to withdraw the prize money and cancel the competition at any time for any reason. Any lawful method to decipher the code is allowed. You are allowed to use any cryptographic methods you like on the cipher number itself rather than solving the 9 riddles. But you are not allowed to use any techniques which are against Australian laws (i.e. you are not allowed to hack my computer, or steal it etc.). If you claim to have won the prize, I have the right to ask for a brief description of how solved one or more of the riddles to ascertain that you have used legal methods. If you are unable to provide a brief description of your method, I have the right to withhold payment of the prize money. This quiz stands as a competition for 7 days starting from the initial upload date (see the watermark in the video). After 7 days the prize is not offered. The prize is also not offered if someone has already posted the correctly deciphered message and won the competition. I am not responsible for any time wasted, damage to property, or injury sustained during the the computation of solutions for these riddles, and you proceed to attempt this quiz entirely at your own risk.

The fix-the-wobbly-table theorem
 
23:14
This video is about the absolutely wonderful wobbly table theorem. A special case of this theorem became well-known in 2014 when Numberphile dedicated a video to it: A wobbling square table can often be fixed by turning it on the spot. Today I'll show you why and to what extent this trick works, not only for square tables but also general rectangular ones. I'll also let you in on the interesting history of this theorem and I'll tell you how a couple of friends and I turned the ingenious heuristic argument for why stabilising-by- turning should work into a proper mathematical theorem. Here is a link to a preprint of the article by Bill Baritompa, Rainer Löwen, Marty Ross and me that I refer to in the video: http://arxiv.org/abs/math/0511490 . This preprint is pretty close to the printed article that appeared in the Mathematial Intelligencer and which lives behind a pay wall, Math. Intell. 29(2), 49-58 (2007). The argument that I show you in this video is somewhat different from the one Bill, Rainer, Marty and I used in our paper. It's a mix of what we do in our paper and the original argument by Miodrag Novacovic as presented by Martin Gardner in his Mathematical Games column. Here is a link to the 2014 Numberphile video on table turning featuring the prominent German mathematician Matthias Kreck http://youtu.be/OuF-WB7mD6k And this is an article by Andre Martin that features an alternative proof for why stabilising-by-turning works for square tables on continuous grounds that are not too steep: http://arxiv.org/abs/math-ph/0510065 Thank you very much to Danil for his Russian subtitles and Marty for his help with getting the draft of the script for this video just right. Enjoy! Burkard

The Greatest Indian Mathematician : Srinivasa Ramanujan

He was born in 1887 in Erode, located in Tamil Nadu.He is recognized as one of the greatest mathematicians f his time, but Srinivasa Ramanujan had almost no formal training in math. He was the second Indian to be inducted as a Fellow of Royal Society, which is a Fellowship of some the world’s most eminent scientists. He joined the fellowship in 1918 at the age of 31, as one of the youngest fellow in the history of the society. He compiled 3900 results (mostly identities and equations), before he lost his life at the age of 32. His infinite series for pi was one of his most celebrated findings. There is also a museum dedicated to telling Ramanujanʼs life story. It is located in Chennai. His birth anniversary, December 22, is celebrated as the National Mathematical Day every year. According to reports, Ramanujan used to jot down his ideas in notebooks, in green ink. His work: He worked on divergent series. He sent 120 theorems on imply divisibility properties of the partition function. He gave a meaning to eulerian second integral for all values of n (negative, positive and fractional). Ramanujan made substantial contributions to the analytical theory of numbers and worked on elliptical functions, continued fractions and infinite. In 1990 he began to work on his own on mathematics summing geometric and arithmetic series. Goldbachʼs conjecture is one of the important illustrations of Ramanujan contribution towards the proof of the conjecture. The statement is every even integer greater than 2 is the sum of two primes , that is 6= 3+3; Ramanujan and his associates had shown that every larger integer could be written as the sum of at most four( example:43=2+5+17+19). Partition of whole number: Partition of whole numbers is another similar problem that captured Ramanujan attention. Ramanujan also, developed a formula for the partition of any number, which can be made to yield the required result by a series of successive approximation. Example 3=3+0=1+2=1+1+1. Numbers: Ramanujan also studied the highly composite numbers which are recognized as the opposite of prime numbers. He studies their structure, distribution and special forms. Fermat Theorem: Ramanujan also did considerable work on the unresolved Fermat theorem, which states that a prime number of the form 4m+1 is the sum of two squares. Ramanujan number: 1729 is a famous Ramanujan number. It is the smaller number which can be expressed as the sum of two cubes in two different ways- 1729 = 13 + 123 = 93 + 103. Cubic Equations and Quadratic Equation: Ramanujam was shown how to solve cubic equations in 1902 and he went on to find his own method to solve the quadratic. The following year, not knowing that the quintic could not be solved by radicals, he tried (and of course failed) to solve the quintic. Euler’s constant: By 1904 Ramanujan had begun to undertake deep research. He investigated the series (1/n) and calculated Euler’s constant to 15 decimal places. Hypo geometric series: Ramanujan also, worked hypo geometric series, and investigated relations between integrals and series. He was to discover later that he had been studying elliptic functions. Ramanujan’s own works on partial sums and products of hyper-geometric series have led to major development in the topic. #theopenbook #Education #Educationalvideos #Studyiq #learn #Cbse #icse #ssc #generalknowledge

Enigma Slide Rule Iinear Cipher Encryption machine
 
09:19
The Enigma slide rule cipher utilizes classic Vigenere polyalphabetic substitution logic in an easy to use yet very secure manner. The linear design also incorporates the use of numbers, special characters, and punctuation. These are rarely seen in ciphers, but they are useful features that can make encoding messages much faster and clearer. This instruction manual will provide examples of using the cipher as well as a helpful worksheet that you can copy and use to help encode or decode your own messages. It can be used and enjoyed by both novices or experts. A series of 5 challenge messages are provided for you to try and solve. Hints are given but the messages get harder as you progress. Answers are provided for the first 4 challenges. Design by Dave Janelle with inspiration from the 1939 “Dick Tracy Secret Code Maker” built by Lawrence Engineering Woods used are Cherry, maple and alder. All markings are laser engraved for both beauty and durability. © 2016 CreativeCrafthouse ® Made in Hudson, Florida available at: http://www.creativecrafthouse.com/index.php?main_page=product_info&cPath=143&products_id=1057
