Modular arithmetic especially the properties of congruence are an important tool in arriving at quick solutions to a variety of problems. In this video Mayank unravels this concept of Congruence starting with the basic concepts and then explaining the 5 key properties of Congruence (≡): a+c ≡ (b+d)mod N (Remainder of Sums ≡ Sum of Remainders) a-c ≡ (b-d)mod N (Remainder of Difference ≡ Difference of Remainders) ac ≡ (bd)mod N (Remainder of Products ≡ Products of Remainders) a^e ≡ b^e mod N (Remainder of Exponent ≡ Exponent of Remainders) a/e ≡ b/e (mod N/gcd(N,e)) (However, don’t do division without writing basic equation Mayank applies these concepts to arrive at quick solutions for 7 representative problems - reducing seemingly impossible math involving large numbers to mere seconds. Some example problems from the video: Find the remainder 6^(6^(6^6 ) )/7 Find the last digit of (17)^16 There are 44 boxes of chocolates with 113 chocolates in each box.

This clip from the 2008 Royal Institution Christmas Lectures shows a simple demonstration of how two people can agree on a secret key, even though all of their communications are carried out in public. In the electronic world, secret key exchange allows computers to communicate securely, and is used, for example, when you give your credit card information to an on-line shop. You can watch the 2008 Royal Institution Christmas Lectures in full at: http://research.microsoft.com/~cmbishop or by visiting the Royal Institution web site. There is a dedicated web site to accompany the 2008 Christmas Lectures, with ten interactive games as well as downloadable PDF instructions for experiments which can be conducted at home or at school: http://www.rigb.org/christmaslectures08

Beware my brothers and sisters, man try daily to master the text without the Set-Apart Spirit the Almighty Father Yahuah sent in Yahusha's name (referencing John 14:26); without life, trying to use scripture for personal gain will come to naught. Let us promote the ability to grow in a relationship with He who brings the letter to life; Yahusha is His name sent by the Almighty Father Yahuah. If you would like a copy of the outlined text for this segment, please contact me and I will get it to you. The description is limited and therefore, I have taken a different approach; thanks for your patience. Shalum.

Security is hard, yet vital for any software these days. After all you don't want to become the laughing stock on hacker news or cause your company to loose billions in shareholder value. This talk won't turn you into a security specialist over night, but you will learn how to avoid common mistakes in your daily work as developer or administrator. I'm going to take you on a brief tour in secure software design, illustrate various attack vectors, and point you to helpful tools and resources. Topics include threat analysis, deployment, parsing, authentication, TLS/SSL, crypto, and user interaction, with some real life examples from my daily work. 30 minutes version from PyCon UK: https://speakerdeck.com/tiran/pycon-uk-2017-everyday-security-issues-and-how-to-avoid-them

Dr. Orr Dunkelman of Haifa University Lecture at TCE Summer School 2013, July 25, 2013 When Cryptography is not the Answer (even when it is) Since modern cryptography has emerged in the mid 70's, it developed a huge set of solutions to many of the security problems: from secure algorithms for communication, to identification of entities, from integrity assurance for programs, to methods for evaluating a function without revealing it. Despite these advances, even the security challenges that were solved by cryptography are still affecting our everyday life: from using old and insecure algorithms, through key management issues, to problems in the interaction between the cryptography and the system where it resides. In this talk we shall consider several examples of such issues, of the gaps between "what is already solved by cryptographers" and "what the security professionals see as unsolved (if not unsolvable)". We will try to isolate the sources for such problems, and look for the changes, both in the technical level and in the perception level, needed from both sides of the security equation (cryptographers and security professionals), to overcome these issues in the future.

VISUALIZING MATH 1 (PDF Book Link) https://gumroad.com/l/visualizingmaths-e-book Blog Link https://visualzingmathsandphysics.blogspot.in 1] How sin( ) is a measure of how much perpendicular two objects/forces are. 2] How cos( ) is a measure of how much parallel two objects/forces are. 3] How in complex numbers i = rotation by 90 degrees i^2= rotation by 180 degrees i^3= rotation by 270 degrees. i^4 = rotation by 360 degrees. 4] Transpose of a matrix = Rotation by 180 degrees around the diagonal. MATRICES AND ITS APPLICATIONS INTUITIVELY AND SIMPLY EXPLAINED. 5] e^i(angle) = rotation by that angle. 6] sin(30) = 1/2 because at 30 degree the effect of a force reduces to half over the other force/object (as against when the two forces/object are against at 90 degrees w.r.t each other) 7) A X B = |A| |B| sin(angle between A and B). VISUALIZING MATH 2 PDF BOOK LINK https://gumroad.com/l/visualizingmath2book Visualizing Math 2 deals with concepts like 1) How Fourier Transforms are the side-view of a wave. 2) Laplace Transforms are side-view + front view (Imaginary + real part) 3) How Z Transforms are nothing but the discrete cousin of Laplace and DFT of Fourier. 4) How the number 1 appears actually as a fraction 1/1 in Math which means full of full. Thus sin(90) = 1/1 = full on influence at 90 deg Thus Max probability = 1/1 = full of full sample space Thus cos(0) = 1/1 = full on full influence at 0 deg (when parallel) Unit Circle radius = 1/1 = magnitude doesn't decrease/increase throughout the rotation. Else it would have been a ratio like 2/1 or 1/4 etc. 5) How Continous functions can be visualized as those functions which you can draw on a paper without lifting up the pencil. 6) How a function differentiable at a point means if you stand at that point,... (1) You will experience a slope. Slope will exist. (2) This slope however will not be infinite. (fully vertical) (3) The slope will be either towards the left or the right but not both the directions. (4) The slope will not wriggle like a snake (oscillate ) at that point. 7) How a hermitian matrix can be visualized as a any object which which exhitibits vertical symmetry. So even if it is rotated upside down about the central axis( diagonal of the matrix) you wont be able to tell the difference. 8) How probability can be visualized much more intuitively by multiplying it by 100 and thus converting it into a percentage. Eg:- a probability of 0.2 can be converted to 0.2 x 100 = 20% 9) How probability density can be understood using an example of the Probability of finding a man after entering New-york v/s finding a man after entering a sparsely populated desert. And so on......... The book is still in works and subsequent updated will be sent to your mail id for free. Binnoy http://visualizingmathsandphysics.blogspot.in

Russian President Vladimir Putin has authoritatively expressed that Russia will issue its own 'CryptoRuble' at a shut entryway meeting in Moscow, as per nearby news sources. The news got through Minister of Communications Nikolay Nikiforov. As per the authority, the state issued digital money can't be mined and will be issued and controlled and kept up just by the specialists. The CryptoRubles can be traded for standard Rubles whenever, however in the event that the holder can't clarify where the CryptoRubles originated from, a 13 percent expense will be demanded. A similar assessment will be connected to any earned contrast between the cost of the buy of the token and the cost of the deal. Nikiforov stated: "I unhesitatingly proclaim that we run CryptoRuble for one basic reason: on the off chance that we don't, at that point following 2 months our neighbors in the EurAsEC will." Grasping and dismissing While the declaration implies that Russia will enter the cryptographic money world, it is not the slightest bit an assertion or legitimization of Bitcoin or some other decentralized digital money. Despite what might be expected, Putin as of late required an entire prohibition on all cryptographic forms of money inside Russia. The announcement from Putin appeared to be evidently to negate the prior remarks from different priests who appeared to be master crypto, however just with controls, and additionally Putin's current gatherings with Buterin and others. Presently, with the issuance of the CryptoRuble, the evident logical inconsistency has been clarified. cryptocurrency cryptocurrency market cryptosporidium cryptography cryptorchidism cryptocompare cryptopia cryptocurrencies cryptozoology cryptocurrency mining crypto crypto news crypto mining crypto wallet crypto exchange crypto calculator crypto reddit crypto meaning crypto aero crypto arbitrage crypto asset fund crypto assets crypto asset management crypto alerts crypto anarchist crypto arbitrage bot crypto api cryptanalysis a crypto botanical champion a cryptocurrency that's not bitcoin a cryptonet a cryptographic self test was performed a crypto miner for your website a crypto nerd's imagination a cryptography expert is deciphering a cryptocurrency a cryptographic evaluation of ipsec a crypto miner crypto bubble crypto bot crypto blog crypto bacteria crypto bitcoin crypto bank crypto bobby crypto bear market crypto buddy crypto blockchain b cryptoxanthin b. cryptococcus neoformans cryptojs b.clamp is not a function cryptowall.b cryptolocker.b cryptodefense.b cryptowall 3.b crypto db_dump suite b cryptography amphotericin b cryptococcal meningitis cryptocurrency news crypto capital cryptocurrency exchange crypto crash c crypto library c cryptographically secure random number c cryptography c crypto lib c-crypto-comp-1.0 c cryptography tutorial c crypto api c. cryptococcus neoformans c cryptography example c crypto example crypto definition crypto disease crypto debit card crypto day trading cryptodaily crypto destroy all humans crypto diarrhea crypto discord crypto derivatives crypto dash d cryptocurrency decryptonite decryptor kryptonite d lock crypto-d crypto.d.ts d wave cryptography d. stinson cryptography theory and practice dnotes crypto cryptogramme d'une carte bancaire crypto etf crypto exchange rates crypto exchanges by volume crypto exchange reviews cryptoeconomics crypto ethereum crypto eos crypto exchange app crypto exchange list e cryptocurrency e crypto source e) cryptology e crypto libertas cryptolocker.e cryptome cryptography ebook cryptography e commerce crypto e juice cryptoflex e-gate crypto fund crypto forum crypto fud crypto fantasy sports crypto faucets crypto facilities crypto futures crypto forecast crypto fiat crypto finance f cryptocurrency f# cryptography f cryptosporidium f_crypto.dll cryptolocker.f cryptowall f-secure cryptolocker.f decrypt cryptonite f-droid cryptolocker.f symantec crypto f360 crypto group limited crypto games crypto group crypto girl crypto graphs crypto graffiti crypto gas crypto gold crypto gram crypto gecko cryptolocker.g crypto g trojan.cryptolocker.g removal trojan.cryptolocker.g (symantec) symantec cryptolocker.g cryptolocker g data cryptowall g data g smart crypto (gnu crypto g&d starsign crypto usb token crypto hedge fund crypto hardware wallet crypto hedge crypto hash crypto hard wallet crypto hustle crypto hodl

What is the mathematical secret behind the barcodes we find on our books? How does it self-check for mistakes? In this extract from his lecture on 'Codebreaking in Everyday Life', John D. Barrow, Gresham Professor of Geometry and Professor of Mathematical Science at the University of Cambridge, explains the maths behind this piece of code we find in our everyday lives. This is the 11th part of 'Codebreaking in Everday Life'. The full lecture is available (in 13 parts) here on YouTube, or it can be downloaded (like all of our lectures) in its complete form from the Gresham College website, in video, audio or text formats: http://www.gresham.ac.uk Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website.
