A Turing machine is a model of a machine which can mimic any other (known as a universal machine). What we call "computable" is whatever a Turing machine can write down. This video is about how it was conceived and why it works. This is the second last video in the CS series (https://www.youtube.com/watch?v=fjMU-km-Cso&list=PLbg3ZX2pWlgI_ej6ZhGd45-cPoWLZD9pT)

версия со слайдами находится по адресу / edited video with slides exist at jetbrains.ru site : http://jetbrains.ru/students/events/neil-jones-programming-languages/ Programs are often treated as data objects, for example in compilers, interpreters, and text editors. Advanced uses include program transformation and analysis, done by supercompilation, partial evaluation, and abstract interpretation. Pathbreaking work has been done in these areas by researchers from Denmark and Russia. In particular, self-application (running a program on itself) has a number of uses. The basic requirements of computability theory: Turing completeness; the existence of a self-interpreter; and the existence of a program specialiser. Program specialisation can be done by either a partial evaluator or by a supercompiler. The first part of the talk concerns programming language interpretation, compilation, and compiler generation. Program specialisation and self-application provide ways to automatically compile or generate a compiler. These possibilities were first seen in the 1970s in Japan and Russia by Futamura and by Turchin, and first realised in practice in the 1980s in Denmark and in Russia. The second part of the talk concerns some high points in computational complexity: what can be computed by programs that run within limited time or memory (storage) bounds? This leads to well-studied hierarchies of computer-solvable decision problems, started by Hartmans and Stearns in the 1960s. The best-known still unanswered question: “ is P = NP? “ (an answer is worth \$1,000,000!) Interestingly, the only general way to prove that more problems can be solved within increased time- or space-bounds is diagonalisation: applying a program to itself in a way very similar to the Futamura projections as used in compiler generation. TOWARDS UNDERSTANDING SUPERLINEAR SPEEDUP BY DISTILLATION Neil D. Jones, DIKU, University of Copenhagen (joint work with Geoff Hamilton, Dublin City University) Distillation is a fully automatic program transformation that can yield superlinear program speedups. It is a further development of supercompilation, initially developed in Russia in the 1970s and in Denmark in the 1990s. Distillation can give superlinear speed-ups on some ``old chestnut’’ programs well-known from the early program transformation literature: naive reverse, factorial sum, Fibonacci, and palindrome detection. The talk describes current work on superlinear program speedups, partly theoretical and partly computer experiments. Further, complexity-theoretic results imply that a large class of exponential-time programs can be converted into second-order polynomial-time equivalents. The idea is to trade time for space, in effect replacing CONS by first-order functions used as arguments in a CONS-free program. An open conjecture is whether distillation or some extension of supercompilation can realise such superlinear speedup transformations in general. Bisimulation is a key to the proof that distillation is correct, i.e., any transformed program has the same semantics as the original. The correctness proof of distillation shows observational equivalence by bisimulation. However, this proof is insensitive to program running times, and does not help to explain how superlinear speedups can occur. A main question: how can a program running in quadratic time be bisimilar to a program running in linear time? This work’s approach is to simplify distillation as much as possible, while maintaining its capacity for superlinear speedups.

Why are there stocks at all? Everyday in the news we hear about the stock exchange, stocks and money moving around the globe. Still, a lot of people don't have an idea why we have stock markets at all, because the topic is usually very dry. We made a short video about the basics of the stock exchanges. With robots. Robots are kewl! Short videos, explaining things. For example Evolution, the Universe, the Stock Market or controversial topics like Fracking. Because we love science.

Roger Schank and Andrew Hacker dispel math instruction. Mathematics is highly overrated for most people and teaching it to everyone is why the standards have become so low. It pointlessly challenges those without interest in it and completely narrows and limits the content for people who want to know more than just algebra. Norman Wildberger shows that they can't even teach trigonometry CORRECTLY. When I hear that grade schools are trying to include calculus, I burst out in laughter. It's OUTDATED! These kids can't even do a dot product, let alone do loopy belief propagation on probabilistic graphical models or use autoencoders in place of singular value decomposition. These kids know so few areas and algorithms. Not only is mathematics one of the most automatable subjects on earth, it largely FOLLOWS discoveries. No, the modern computer was NOT based upon Turing (rehashed the silly diagonalizations of Godel and Cantor) and the airplane wasn't discovered by studying Newton (simple action-reaction displacing air) or Navier-Stokes. The mathematician couldn't even say why wings can fly UPSIDE DOWN (simple angle of attack ). Even the jet engine was not a straightforward application of math. People like to talk about Maxwell's equations (can be reduce to one equation with geometric algebra), but the actual discoverer (Faraday) was not very good at math. The charlatans get all the credit. Grassmann was actually a theologian and he discovered the most useful branch of math, which is linear algebra. Idiots like Gauss wondered about 17-gons but with a piece of string and Archimedes' spiral one can trisect the angle, square the circle, inscribe polygons and do inverse trig. They just refused to use string. Trivial! A simple bisection algorithm gives you guaranteed roots to ANY degree polynomial (in about 10 lines of code), where Galois showed analytical methods fail at the meager 5th degree. Simple N-body algorithms also solve more than the pathetic limit proved by Poincare of two bodies. They're trivial algorithms with computers. Poincare dispelled 20th century set theory and called it a useless Bourbaki disease, like modernist art. No TRULY creative math is done using ZFC and modern analysis has been ripped to shreds by those like Doron Zeilberger and Solomon Feferman. The proofs don't even work logically. Analysis is really just a cover for finite algebra. If you study modern gauge theory, you will understand that physicists pretend to have problems like chiral fermions in the lattice but it has all been solved. String theory is a comical joke. Mathematicians pretend we need to study prime factoring for cryptography but lattice-based methods make this silly. Even GPS can forget about SR and GR, making them systematic calibration errors (much larger calibrations are to do with other phenomena). Optimization, bootstrapping, numerical methods, perturbation, approximation, finite element method, computational fluid flow, machine learning, computer algebra systems, etc... takes care of all the real world mathematics with little skill involved. Modern mathematics is more like post-modern art subsidized by the government, so Ivy League jerkoffs can live at the public's expense. Don't listen to the Sputnik propaganda.

The field of computer science summarised. Learn more at this video's sponsor https://brilliant.org/dos Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other.

Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work! 2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example. 3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

►Watch the replay here: https://www.youtube.com/watch?v=dVzsptlVm28 ►What is Neymar Jr's Five? The name of the event comes from there being five players on each team, but there's little other comparison with regular five-a-side. There are no goalkeepers for a start, and every time someone scores their opponents lose one player, until 10 frenetic minutes are up or one team runs out of players. A draw leads to a one-on-one play-off situation to decide the result.  Catch up on all of the action from the Neymar Jr's Five World Final in Brazil, where Mexico's Deportivo Mago and local heroines Resenha 013 outplayed them all to be crowned 2018 world champions. No sooner does Neymar Jr return from starring for his country in the world's biggest football tournament than he's back where it all began for him, at Praia Grande near Santos in Brazil for the third running of his own highly anticipated soccer competition, the Neymar Jr's Five World Final 2018.After qualifiers in 62 countries that featured 34,944 players in  9,588 matches, only the very best made it to play in the World Final of the planet's biggest five-a-side football tournament at the Instituto Projeto Neymar Jr. Watch the full event again in the player below and then read on to find out who was crowned Neymar Jr's Five 2018 champions. Mexico's title-winning Deportivo Mago didn't even need the full 10 minutes to beat Argentina's Ofensivo in the mixed final. After winning all eight of the their previous matches over the weekend, the Mexicans dominated the final game, running out 5–2 winners over their Argentinian rivals with 1m 10s still left on the clock. _ Experience the world of Red Bull like you have never seen it before.

Sending an email message is like sending a postcard, says scientist Andy Yen in this thought-provoking talk: Anyone can read it. Yet encryption, the technology that protects the privacy of email communication, does exist. It's just that until now it has been difficult to install and a hassle to use. Showing a demo of an email program he designed with colleagues at CERN, Yen argues that encryption can be made simple to the point of becoming the default option, providing true email privacy to all.

Computers, algorithms, and artificial intelligence have touched every aspect of our society, from science, to communication, to the justice system. But despite their enormous power, computers have fundamental limits – problems that no program can solve, and thorny issues in fairness and human rights. During the 26th year of the popular Ulam Lecture Series, SFI Professor Cristopher Moore looks at two sides of computation – the mathematical structures that make problems easy or hard, and the growing debate about fairness in algorithmic predictions. These two lectures are self-contained, and can be enjoyed together or separately. Lecture 1: Easy, Hard, and Impossible Problems: The Limits of Computation Monday, September 24, 7:30 pm Every day we ask computers to solve problems for us – to find the fastest route across town, the shape a protein folds into, or a proof for an unsolved mathematical question. For all these problems, the space of possible solutions is vast. Why is it that for some problems, we can quickly zoom in on the solution, while for others it's like looking for a needle in a haystack? What is it about the structure of a problem that makes it easy, or hard, or even impossible to solve? Moore draws analogies between computation and evolution, and takes us from the simple puzzles to the heights of universal computation, Turing's halting problem, and the nature of mathematical truth and creativity.

All primes up to answer are computed using the sieve of Eratosthenes. If your answer is empty 12000 is used. A note corresponding to the marked number is played. The stopwatch stops when the sieve is done, but after that the non-primes are deleted from the list, which can take a long time. You can toggle hide or show the list by clicking on the stage, and when hidden the computations are much faster. https://scratch.mit.edu/projects/135346157/#player http://phosphorus.github.io/app.html?id=135346157&turbo=true&full-screen=true

How does a Neural network work? Its the basis of deep learning and the reason why image recognition, chatbots, self driving cars, and language translation work! In this video, i'll use python to code up a neural network in just 4 minutes using just the numpy library, capable of doing matrix mathematics.
