Simon Singh: "The Simpsons and Their Mathematical Secrets" | Talks at Google
 
41:27
Simon Singh, author of the bestsellers Fermat's Enigma, The Code Book, and The Big Bang, offers fascinating new insights into the celebrated television series The Simpsons: That the show drip-feeds morsels of number theory into the minds of its viewers—indeed, that there are so many mathematical references in the show, and in its sister program, Futurama, that they could form the basis of an entire university course. Recounting memorable episodes from "Bart the Genius" to "Homer3," Singh brings alive intriguing and meaningful mathematical concepts—ranging from the mathematics of pi and the paradox of infinity to the origin of numbers and the most profound outstanding problems that haunt today's generation of mathematicians. In the process, he illuminates key moments in the history of mathematics, and introduces us to The Simpsons' brilliant writing team—the likes of David X. Cohen, Al Jean, Jeff Westbrook, and Stewart Burns, all of whom have various advanced degrees in mathematics, physics, and other sciences. Based on interviews with the writers of The Simpsons and replete with images from the shows, facsimiles of scripts, paintings and drawings, and other imagery, The Simpsons and Their Mathematical Secrets will give anyone who reads it an entirely new insight into the most successful show in television history.

The Map of Mathematics
 
11:06
The entire field of mathematics summarised in a single map! This shows how pure mathematics and applied mathematics relate to each other and all of the sub-topics they are made from. If you would like to buy a poster of this map, they are available here: http://www.redbubble.com/people/dominicwalliman/works/25095968-the-map-of-mathematics I have also made a version available for educational use which you can find here: https://www.flickr.com/photos/[email protected]/32264483720/in/dateposted-public/ To err is to human, and I human a lot. I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors! 1. The number one is not a prime number. The definition of a prime number is a number can be divided evenly only by 1, or itself. And it must be a whole number GREATER than 1. (This last bit is the bit I forgot). 2. In the trigonometry section I drew cos(theta) = opposite / adjacent. This is the kind of thing you learn in high school and guess what. I got it wrong! Dummy. It should be cos(theta) = adjacent / hypotenuse. 3. My drawing of dice is slightly wrong. Most dice have their opposite sides adding up to 7, so when I drew 3 and 4 next to each other that is incorrect. 4. I said that the Gödel Incompleteness Theorems implied that mathematics is made up by humans, but that is wrong, just ignore that statement. I have learned more about it now, here is a good video explaining it: https://youtu.be/O4ndIDcDSGc 5. In the animation about imaginary numbers I drew the real axis as vertical and the imaginary axis as horizontal which is opposite to the conventional way it is done.

Why cryptography and information Security course
 
05:08
www.hiteshChoudhary.com www.newdemy.com Cryptography What is cryptography? Cryptography (or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties (called adversaries).More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Yeah, I know that you have read the above lines many times. These are perfectly true jargons. It’s just something like our brain is made of 80% of water, technically true but it doesn’t explain things much. When I tried to study Cryptography, it was tough. When anyone wants to learn HTML, he can find a lots of resources on internet but when things come to Cryptography you need to buy a lots of books and watch a lots of youtube videos which contains an annoying background music. A lots of blog are also helpful but all are fragmented. So, I decided that it is a good time to put Cryptography course. The course will be beginners friendly and will teach you a lot of things about Information Security. This series is not meant for 2 communities of people over the internet. 1. Not bothered about Computer Security 2. True Computer professional [Advanced programmers and crypto masters] The category one does not fit into any computer security course as information security comes at very last in their priority list. Hence, most of the time they are the practice playgrounds for most of the hackers. The category two has moved into the immense knowledge of information security. And they know all the stuff or most of the present stuff about it. So, they will feel bore in this series because they are the inventor of most of the stuff. Rest of the people are going to love this cryptography online video series. The candidates for which I am looking to take this cryptography course are: 1. University Students 2. Hackers a. Fretos : The freshers b. Practos: The practical ones University Students will be interested in this course as most of the Universities have curriculum of Cryptography. The second category is of hackers but I have divided them into 2 major categories. First one is Fretos, these are fresher in information security and are trying to learn stuff. It is a good time for them to start this series because you will understand terms like MITM, RSA, MD5 and DSA. Second category is hackers who have learned most of the things practically. Personally, I am very impressed that you have gained so much of knowledge. You might have knowledge about hacking into various accounts and systems or even knowledge of creating exploits. But ask a simple question to yourself, you are a pro in hacking skills but have no idea about RSA or Block ciphers. You know to break WEP in wireless but no idea of WEP encryption or cryptic flaw in algorithm. I hope that you have got my point. So, let’s get started.

EP 065: How to master trading psychology, and introduce new best practises w/ Brett Steenbarger For this episode, I interviewed a very special guest; Dr Brett Steenbarger (after many, many requests from listeners). Brett is a very well known trading psychology coach, and has consulted to some of the biggest names in the industry. He’s also a respected author who has now published four books, some which have been recommended reading by previous guests on this podcast. During our conversation, I asked Brett how to break bad trading habits and introduce new best practises, to explain why traders need to be adaptable in markets, plus how we should think about goal setting and measure progress. And of course, much more about how to enhance your performance as a trader. - - - - - - LINKS - - - - - - · More interviews: http://chatwithtraders.com · Free resources: http://chatwithtraders.com/resources · Twitter: https://twitter.com/chatwithtraders · Facebook: http://facebook.com/chatwithtraders · Instagram: https://instagram.com/chatwithtraders_ · Soundcloud: https://soundcloud.com/chat-with-traders · Stitcher: http://www.stitcher.com/podcast/chat-with-traders

A Physics and Computer Science Genius Discovers a New Kind of Science (2003)
 
01:17:41
Stephen Wolfram (born 29 August 1959) is a British scientist known for his work in computer science, mathematics, and in theoretical physics. He is the author of the book A New Kind of Science. About the book: https://www.amazon.com/gp/product/1579550088/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=1579550088&linkCode=as2&tag=tra0c7-20&linkId=078fb475b826442c7036b51700dda76c In 2012 he became a fellow of the American Mathematical Society. He is the founder and CEO of the software company Wolfram Research where he worked as chief designer of Mathematica and the Wolfram Alpha answer engine. His recent work has been on knowledge-based programming, expanding and refining the programming language of Mathematica into what is now called the Wolfram Language. His book An Elementary Introduction to the Wolfram Language appeared in 2015. By age 15 he began research in applied quantum field theory and particle physics and publish scientific papers. Topics included matter creation and annihilation, the fundamental interactions, elementary particles and their currents, hadronic and leptonic physics, and the parton model, published in professional peer-reviewed scientific journals including Nuclear Physics B, Australian Journal of Physics, Nuovo Cimento, and Physical Review D.[29] Working independently, Wolfram published a widely cited paper on heavy quark production at age 18[3] and nine other papers,[15] and continued research and to publish on particle physics into his early twenties. Wolfram's work with Geoffrey C. Fox on the theory of the strong interaction is still used in experimental particle physics.[30] He was educated at Eton College, but left prematurely in 1976.[31] He entered St. John's College, Oxford at age 17 but found lectures "awful",[15] and left in 1978[32] without graduating[33][34] to attend the California Institute of Technology, the following year, where he received a PhD[35] in particle physics on November 19, 1979 at age 20.[36] Wolfram's thesis committee was composed of Richard Feynman, Peter Goldreich, Frank J. Sciulli and Steven Frautschi, and chaired by Richard D. Field.[36][37] A 1981 letter from Feynman to Gerald Freund giving reference for Wolfram for the MacArthur grant appears in Feynman's collective letters, Perfectly Reasonable Deviations from the Beaten Track. Following his PhD, Wolfram joined the faculty at Caltech and became the youngest recipient[38] of the MacArthur Fellowships in 1981, at age 21. From 1992 to 2002, he worked on his controversial book A New Kind of Science,[3][50] which presents an empirical study of very simple computational systems. Additionally, it argues that for fundamental reasons these types of systems, rather than traditional mathematics, are needed to model and understand complexity in nature. Wolfram's conclusion is that the universe is digital in its nature, and runs on fundamental laws which can be described as simple programs. He predicts that a realisation of this within the scientific communities will have a major and revolutionary influence on physics, chemistry and biology and the majority of the scientific areas in general, which is the reason for the book's title. Since the release of the book in 2002, Wolfram has split his time between developing Mathematica and encouraging people to get involved with the subject matter of A New Kind of Science by giving talks, holding conferences, and starting a summer school devoted to the topic. In March 2009, Wolfram announced Wolfram|Alpha, an answer engine. Wolfram|Alpha later launched in May 2009,[52] and a paid-for version with extra features launched on February 2012.[53] The engine is based on natural language processing and a large library of algorithms, and answers queries using the approach described in A New Kind of Science. The application programming interface allows other applications to extend and enhance Alpha.[54] Wolfram believes that as Wolfram Alpha comes into common use, "It will raise the level of scientific things that the average person can do."[55] Wolfram|Alpha is one of the answer engines behind Microsoft's Bing[56][57] and Apple's Siri answering factual questions.[58] In June 2014, Wolfram officially announced the Wolfram Language as a new general multi-paradigm programming language.[59] The documentation for the language was pre-released in October 2013 to coincide with the bundling of Mathematica and the Wolfram Language on every Raspberry Pi computer. While the Wolfram Language has existed for over 25 years as the primary programming language used in Mathematica, it was not officially named until 2014.[60] Wolfram's son, Christopher Wolfram, appeared on the program of SXSW giving a live-coding demonstration using Wolfram Language and has blogged about Wolfram Language for Wolfram Research. https://en.wikipedia.org/wiki/Stephen_Wolfram Image By Hartlend (Own work) [CC BY-SA 4.0 (http://creativecommons.org/licenses/by-sa/4.0)], via Wikimedia Commons

Master Yonghua: "Introduction to Chan Meditation" | Talks at Google
 
57:10
Chan Meditation: Maximizing Well­-Being, Productivity and Creativity In this talk, Dharma Master YongHua introduces superior advantages of Chan meditation. Chan increases our concentration power(samadhi). With greater concentration, mental and physical functions are maximized. Physically, our health and well-being improve; and mentally, our productivity and creativity are enhanced. Chan is the school of Buddhism that specializes in meditation. Chan flourished in China, and later was imported as “Zen” into Japan. It has been practiced throughout East Asia for more than 2,000 years. Born in South Vietnam, Master YongHua earned a BS in Mathematics from the University of Minnesota and an MBA from the University of Chicago. After working in corporate management, in 1995 Master YongHua left the corporate life to become a monk and study with Great Chan Master XuanHua. In 2005, after ten years of meditation training and over three years of solitary retreat, Master YongHua began teaching. He is currently the abbot of Lu Mountain Temple in Southern California. For the last 11 years, he has lectured on Mahayana, taught chan, and authored several books.

2007-09-05 CERIAS - Applying Recreational Mathematics to Secure Multiparty Computation
 
49:30
Recorded: 09/05/2007 CERIAS Security Seminar at Purdue University Applying Recreational Mathematics to Secure Multiparty Computation Yvo Desmedt, University College, London The problem of a mice traveling through a maze is well known. The maze can be represented using a planar graph. We present a variant of the maze. We consider a grid vertex colored planar graph in which an adversary can choose up to t colors and remove all vertices that have these colors and their adjacent edges. We call the grid in which these vertices and adjacent edges are removed a reduced grid. The problem is that a mice must be able to move in the reduced grid from the first row to the last row, and from the first column to the last column, and this for all possible reductions. We present three types of solutions to construct such grids. The efficiency of these solutions is discussed.The problem finds its origin in the problem of secure multipartycomputation. Imagine going to a medical doctor in Iraq who needs to prescribe some medication, which might be counterindicated. The typical solution is to disclose all medical records to the doctor. If secure multiparty computation would be used, the medical doctor in Iraq only learns from the distributedmedical databases whether the medication is, or is not, counterindicated. We consider the problem of parties each having a secret belonging to a non-abelian group. The parties want to compute the product of these secrets without leaking anything that does not follow trivially from the product. Oursolution is black box, i.e., independent of the non-abelian group. This has applications to threshold block ciphers and post-quantum cryptography.

About the Centre The Centre aims at the promotion of interdisciplinary research in Mathematics, Computer Science and Statistics towards furtherance of teaching, research as well as training and development in Cryptology and Cyber Security. It acts as a national hub for cryptographic requirements, cutting-edge research activities and indigenous capacity building in all relevant fields of study. Major activities of the Centre include teaching, training and research in Cryptology and Security. The Centre promotes sustained collaboration in focused research areas, and serves as a meeting point for eminent scholars. It also conducts training programs targeted to produce a critical mass of experts to cater to the national and international requirements in this niche area. Welcome to Indian Statistical Institute (ISI), a unique P. C. Mahalanobish institution devoted to the research, teaching and application of statistics, natural sciences and social sciences. Founded by Professor P.C. Mahalanobis in Kolkata on 17th December, 1931, the institute gained the status of an Institution of National Importance by an act of the Indian Parliament in 1959. The Headquarters of ISI is located in the northern fringe of the metropolis of Kolkata. Additionally, there are four centres located in Delhi, Bangalore, Chennai and Tezpur. Research in Statistics and related disciplines is the primary activity of the Institute. Teaching activities are undertaken mainly in Kolkata, Delhi and Bangalore. Offices of the Institute located in several other cities in India are primarily engaged in projects and consultancy in Statistical Quality Control and Operations Research'. Indian Statistical Institute (ISI) is an academic institute of national importance as recognised by a 1959 act of the Indian parliament. It grew out of the Statistical Laboratory set up by Prasanta Chandra Mahalanobis in Presidency College, Kolkata. Established in 1931, this public university of India is one of the oldest and most prestigious institutions focused on statistics, and its early reputation led it to being adopted as a model for the first US institute of Statistics set up at the Research Triangle, North Carolina by Gertrude Mary Cox. Mahalanobis, the founder of ISI, was deeply influenced by wisdom and guidance of Rabindranath Tagore and Brajendranath Seal. Under his leadership, the institute initiated and promoted the interaction of Statistics with natural and social sciences to advance the role of Statistics as a key technology by explicating the twin aspects – its general applicability and its dependence on other disciplines for its own development. The institute is now considered as one of the foremost centres in the world for training and research in Computer science, Statistics, Quantitative Economics and related sciences. ISI has its headquarters in Baranagar, a suburb of Kolkata, West Bengal. It has four subsidiary centres focused in academics at Delhi, Bangalore, Chennai and Tezpur, and a branch at Giridih. In addition, the Institute has a network of units of Statistical Quality Control and Operations Research at Vadodara, Coimbatore, Hyderabad, Mumbai and Pune engaged in guiding the industries, within and outside India, in developing the most up–to–date quality management systems and solving critical problems of quality, reliability and productivity. Primary activities of ISI are research and training of Statistics, development of theoretical Statistics and its applications in various natural and social sciences. Originally affiliated with the University of Calcutta, the institute was declared an institute of national importance in 1959, through an act of Indian parliament, Indian Statistical Institute act, 1959. ISI functions under the Ministry of Statistics and Programme Implementation (MOSPI) of the Government of India.Key areas of expertise of ISI are Computer science, Statistics, Mathematics, Mathematical economics, Operations Research and Information Science and it is one of the few research oriented Indian schools offering courses at both the undergraduate and graduate level.

The rationality of luck -- chaos, randomness and information: Chew Lock Yue at TEDxNTU
 
21:43
As we face the world of uncertainty every day, we hope for the best outcome, i.e. we hope to be lucky. But could we rationalize luck? This talk is on the human endeavour to rationalize luck by quantifying it, and to use information to take advantage of it, especially on a type of deterministic system that exhibits randomness via chaos. Lock Yue is an Assistant Professor in the Division of Physics and Applied Physics, School of Physical and Mathematical Sciences, Nanyang Technological University. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
