  1. For those who said "I don't understand this"…

    As far ad I can tell, this series is one of the BEST tutorials you can find in earth about fourier & other math topics in engineering,

    If you still cannot understand what he said, that means your math sucks and this is not for you. Stop learning something that you are not going to use in your whole life.

  2. Very Talented and passionate MIT professor!! My Calculus professor isn't bad but Mechanics professor sucks!, Gf doesn't. even he has got a M-phil in Maths but his way of teaching is 20 years old "writing his notes on the whiteboard in order to solve the textbook questions, then he gives us his solved notes." One can learn Derivatives, Integration and General theorems but the Definite Integrals, Plane Curves and Analytical Geometry of three dimensions doesn't get absorbed in my damn head. Thanks MIT for free stuff!

  3. I would like to know whether this is mathematical modeling lecture e.g population models, difference equations and differencial equations? If not where can I find lectures on mathematical modeling?

  4. Teach you and no to grade you. Some/Many professors must watch these videos to learn teaching and even sciences. A professor that understands what he is explaining

  5. I am from Greece I like very much USA education and Us professors .They are really free in mind like your country and also they supply the students with very accurate knowledge and passion in their field without stealing their time or making them tired in the lecture.I have all the books of this extraordinary professor translated in Greek of course.I think they are translated in many other languages also.Nice that we watch the lectures so far away…

  6. 7/11 was a part time job. What do you think about this MIT OpenCourseWare? In what course will I learn Linear Algebra on the level of Hoffman and Kunze?

  7. Is that Professor Strang? I e-mailed him a while ago and he still has to send me the "Introduction to Linear Algebra" book or something like that.

  8. Just the greatet professor in all of MIT. I like how he hits the board hard with the chalk going "tock-tock-tock-tock-tock-tock" or something like that. Hit it hard, Professor Strang! Long live the chalk-hitting professor!

  9. Hi MIT thanks for the previous reply. Please tell me is their an 18.04 and an 18.05 course before the linear Algebra 18.06 course? Thank you

  10. Great class, Professor.
    So glad that MIT is sharing your classes with us =)

    But, I have one doubt.
    Why is 1 for when the structure is free and 2 for fixed structure?
    Is there an explanation for these number?

  11. Is your lifes o empty you need listen to this crap? You live once.. Go party. You dont need stuff or a career.

  12. What the matrix can be called if the non-zero elements and zero elements are equal?
    Sparse (for having more zeros) and dense (for having more non-zeros)

  13. This is a clear explanation. I just feel like being in the class and listen for explaining from the great Prof. Gilbert Strang. Love it… Thanks for MIT OCW..

  14. finite element and eigenvalues are elusive to me. actual equations for actual problems are rarely done. CSULB had math both ways. F = KX   ? You can see JAMMA boards on EBAY. The computers of today are simpler than FORTRAN computers of 1970 s. COMPILERS would set gate paths ahead of time. Actual circuits wouldf change. In the ghz speed . a lot of back and forth to the same data and address bus can be slow  More than 1 data bus was used on the FORTRAN computer. I think the compromise is to make a 500 mhz BASIC computer with just the non paul allen approved microprocessor. SAME as earlier BASIC computers. FLOW chart for writing the program line into memory 1 8 bit character at a time starting with parentheses.
