    Very nice to see Standford providing lectures for the public for free. Not everyone can afford a Stanford education. Hell! I can't afford any education but I can afford my ISP bill + TH-cam + Standford and other colleges allowing lectures to be shown on TH-cam are a great service to the public and the world over.

      True but Algebra was already in existence before Muslims in Egypt, India, Greece, China. The term Algebra was given by Europeans. In India it is called Bijganit and predates 6th century. In fact, many ancient countries have own names for Algebra.

    Is it just me, or does Professor Devlin look and sound like Doctor Who? The twelfth Doctor played by Peter Capaldi, which in my opinion was the GREATEST Doctor EVER in the entire franchise... He DID seemed a little nervous with the habitual walking back and forth (which was probably due to the fact that he was playing to an audience of his peers on the internet, as well as the fact that he wasn't lecturing to a bunch of 18yo kids he can yell at and make fun of, his audience were full grown adults his age or more). Even so, his mind and explanations we're great, and his ad hoc answers to audience questions were PHENOMENAL Also, great smile and energy. Thank you Professor Devlin... Sorry if I keep expecting a Scottish accent from you...

The professor is not saying that KHARZAMI is the inventor of ALGEBRA. All he is talking about that the word ALGEBRA---- first used was by Mohammad Al-Kharzmi in his famous book. But Algebra was already present, with different nations /countries, with different names. But the word--- ALGEBRA was started by MOHAMMAD AL-KHARZEMI.

    1:20:46 Completely voting again after people are eliminated is how the UK Tory party elect their leader in the second stage of the voting process. In Stage Two of the voting process, when a candidate is eliminated, a new election is held by the MPs, and the voting process is repeated until there are only two candidates remaining, at which point the entire Tory party is allowed to vote for the preferred leader. It is interesting to observe that in Stage Two of the process, when certain candidates know that they have plenty of votes, some of them ask certain supporters to not vote for them, and instead vote for opposing candidates that are deemed weak, in order to try to eliminate potential strong opposing candidates.

    I really commiserate with the speaker, watching him interact with audience members trying to explain what is going on in higher mathematics. When he tries to explain what is happening in linear algebra and higher algebra (group theory, galois theory, etc) I really felt the twinge of pain in his eye. It's tough to make people understand what mathematics actually is, when their highest notion of algebra is highschool algebra.

    Since everyone else is being so technical about peoples origins, then I can say that Fibonacci was not italian. Italy did not even exist. He was from Pisa, its own little entity. Yet we still, for all intents and purposes call people like DaVinci, Fibonacci, The Medici's Italian. Which is sufficient for the type of discourse being presented (I think).

      Yes, there are. His scenarios with millions of people picking, just from 4 of the 64 possible patterns, are so unlikely that one yould have to question either his understanding or intent.
      He tells the woman who asks if you only vote for candidate A and no lower preferences. That this strengthens her vote for A. This is wrong because lower preferences only apply after A has been eliminated. All it means is that her vote is not transferred to her next choice after A has already lost. It makes no difference to A besause A is already out.

    The word algebra is derived from operations described in the treatise written by the Persian mathematician, Muḥammad ibn Mūsā al-Ḵhwārizmī, titled Al-Kitab al-Jabr wa-l-Muqabala (meaning "The Compendious Book on Calculation by Completion and Balancing") on the systematic solution of linear and quadratic equations. Al-Khwarizmi is often considered the "father of algebra", for founding algebra as an independent discipline and for introducing the methods of "reduction" and "balancing" (the transposition of subtracted terms to the other side of an equation, that is, the cancellation of like terms on opposite sides of the equation) which was what he originally used the term al-jabr to refer to.[9] His algebra was also no longer concerned "with a series of problems to be resolved, but an exposition which starts with primitive terms in which the combinations must give all possible prototypes for equations, which henceforward explicitly constitute the true object of study." He also studied an equation for its own sake and "in a generic manner, insofar as it does not simply emerge in the course of solving a problem, but is specifically called on to define an infinite class of problems."[10]

    I have always thought that you should get the number of votes you got. So if you get 10,000 votes in the election then you have 10,000 votes in the parliament. There are many people in parliament for each electorate. Obviously you would need some lower cutoff or there would need some lower cutoff saying you need a minimum member of votes. If your second person was elected then they would get ½ a vote from you. I think that might work better. As an alternative to a minimum number of votes you could say have three candidates for each electorate.

    Arabic culture as we know assimilated Hellenic culture who used the letters of the Greek alphabet to represent numbers. They also absorbed Hindu culture who used the symbols for numbers we used today. Notationally we can see the Eureka moment Arab scholars must've had when translating Greek works into Arabic already having the Hindu-Arabic symbols for their analyses.

China have been making huge investments in Africa to help support their growing economy, and this has helped fuel growth there.
      I think Latin America is also a potential future world leader in scientific research. There is a contagious wave of social and economic reform going on all around South America that I think will lead to an age of enlightenment there.

    Geometric algebra is/was hampered by the precision of drawings. You can construct the sqrt of every natural number iteratively, but it gets very tedious and You would need acres of paper to get the precision needed by doing iterations. In numeric arithmetic going trough the needed iterations is easier to get to a desired/practical precision. (the Geo_method is Pythagoras: 1²+1² ->sqrt2; (sqrt2)²+1² = 3² ->sqrt3; (sqrt3)²+1² = 4² ->sqrt4 ... just draw a perpendicular Length_1 to the end of the Previous resultLine)
    Geometry failed because they didn't/couldn't go trough iterative constructions; and We/OurBrains can't do Geometry purely verbally, You need paper and a sharp pencil.

      in fact its now known that there is no distinct genetically Persians or Arabs, seeing as they were both empires at one point you can assume substantial gene flow. Take it from a biologist. These are LINGUISTIC, not genetic differences. now this may blow your mind, but in humans the genetic difference between individuals in a population is more than between one population and another.
      soo....The variation WITHIN the "Persian" group would be MORE than the variation BETWEEN the Persian group and some other group.

    Geometry is much more fun; so if You can present a second solution, an analog geometrical construction to solve an Arithmetic problem it is more intriguing/attractive to learn, understand and remember.

    Been listening for a little while and honestly I am less than completely impressed. At about the halfway point he tells a story about how, in his intro calculus he was the only student who really thought about why calculus formulas work, and everyone else in the class was content to mindlessly move numbers around on paper according to arbitrary rules. I doubt it. He seems to think he is uniquely intelligent and no one else thinks on a deep level but him. It's kind of immature, honestly.

      Yes but as the professor mentioned he was of the opinion that it was written in the Arabic language thus it is Arabic. The trend here is that From Babylon, to India, Greece, and Persia it seems that every nation used some sort of Algeria and that Math is always consistent no matter what nation was in power. I would rather think of them as Mathematicians over Persians, Greeks, Italians, Arabs, etc. Also, algebra was always there but we lost and rediscovered 1ir with every nation that was conquered.

    Zero was for the first time created by Arabic and Muslim mathematecians rather than by Indian mathematecians.
    The whole Arabic numbers were created using the principle of angles as in the following way:
    Number zero means there is no angle in the number zero: 0
    Number one means there is one angle in the number one: 1
    Number two means there are two angles in the number two: z which becomes 2
    Number three means there are three angles in the number three such as a standing lettre w which becomes 3
    And so on

    Sheer ignorance on how quadratic equations, geometry, trigonometry and algorithms were formed. Al khaarizmi only translated Indian knowledge and took credit for it. Till he came along Arabs could not count. They could not even write dates and suddenly they had a maths genius who in a span of months solved most equations and brought algorithms. This too when he was more than 50 years old. Till then nobody had heard of him and till then he had no contribution to maths in any form or even basic arithmetic. This is where Islamic propoganda. We Indians won't fall for it. We know the truth.

    Arabic Mathematics ??? He was Iranian like 95% others old scientists Avicenna,Frabi,Tussi, Khayyam, Kashi, ,Razi (Alcohol) ,Haytham (blood circulation) Khwarizmi , Banou, Battani, Marwazi , Farisi, Sahl , Wafa, or ,Alhazen . Iranian are not Arabs see .Muslims also are not Arabs . Iranians was forced to become Muslim after the Arab invasion. Arabs Burned the books and were against all knowledge but Koran .Iranian Scientists had to translate their works in Arabic to exist.All this Persian or Iranian knowledge gave birth to "Renaissance" and "Age of Enlightenment" "Siecle des lumières" in Europe. Newton ,Kepler , Descartes, and many others copy their works.Today there is not even one word in the school books about Iranians huge help to the actual science we all are using.Its good to mention 5 Greek philosophers but its also normal to talk about the roots of the sciences. Today Arabs have still no significant impact in science , but they try to furnish their empty science room with Iranian scientists and call it "Islamic Sciences " 2 words that are totally opposite. Saudi Arabia , Qatar or other Arabic countries know better how to buy 5 stars Hotels and Soccer clubs with petrodollars .

      +Ashish choubey bols show me by facts ,how? what knowledge ? when and how Indian s gave to Persian. I will be curious to learn. Persian ancestors were Sumerians,mess and Assyrians. Not Indians. Indians never invaded Persia.Nader SHah of Persia invaded India in 18th century. So Persian empire influenced India. There are still many Persian words in Indian language. We are talking about very famous Persian scientists around Arabs invasion or Mogul invasion.
      Pls bring facts dates, names of Indian scientists and references. What exactly was given or brought to Persian scientists ? . ( like Copernic , Descartes, Kepler or Newton who took everything from Persian scientists )
