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..
rare people with these skills.Possibly few of the rarest on this planet a) Highly knowledgeable b) Good skills in explanation c) and most importantly interest in explaining things
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
MIT provides us foreign college students a path to the courses taken by American undergraduates.Thanks to it,we can manage the skills in understanding the lectures given by American professors in English. I hope I would take the PHD of computer science in MIT in the coming future. Thank you,MIT.
It's really great to see such an old professor showing full energy. Beats me. I gotta stop being lazy and put in smart hard work. Btw thanks for the vid.
Thanks for this video. It was getting a bit deep and mysterious for me with the springs, masses and free/fixed discussions but hopefully will make more sense in future lectures...
You said lecturer say something, I said what you're saying shall not be forgotten in memory time by those interested minds in this point in time and hope it won't be cut off by the editor or by the RNA cutters coz it could be transferred to the other side and the effort counts no flattery frankly speaking like the other mindsets doing their thing for what they are like compilations.
This dude is great! Id love to have his class. Id be able to really learn and enjoy the content rather than stress about grades. I mean give easy B’s to people who put in the effort and if you do somewhat more than you need you should get an A.
getting good professors is really rare. Most professors of their generation and I mean like 40+ aren't really good. Most students learn from external sources like books and videos made by people who are like 20+ yrs old more than they learn from sitting in classes. I think this generation knows it well how important explaining concepts, going in details, giving real life examples, etc. are and so when our kids will go to colleges the professors might actually be good since they know how it is.
You got that right, I had a dream of going to MIT a few years ago but I don't need to now. I can continue with my state school and maybe from these lectures go to graduate school at MIT instead of the undergraduate I initially wanted.
Thank you for uploading this excellent video. am very lucky at least i could attain partially lecture of such brilliant professor specially regarding one of my interesting subject. Please upload videos as more as possible.
Why not allow life long students above age 50 to actually earn a degree from passing exams related to your online courses. Many of us were unable to complete degrees earlier in life due to pressures of family and financial obligations. Many of us have become successful as self taught business owners. This would be a wonderful contribution to society and in particular to our longer living adults who may have a lot to offer back to society. MIT should take this to the next level. Glenn DSM labs
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!
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?
the mass-spring analogy was let open by context. I guess the key idea is a expression F = -K*X, where: * F is the n x1 matrix of the total forces acting of each of the masses; * X is the n x1 matrix of the positions of each of the masses; * K is the n x n matrix of the system that maps positions to forces produced by the springs. all springs have zero natural length and constant k = 1.
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)
There are two versions of the same lecture seris 18.085. Can somebody suggest which one to follow. There are some basic areas missing in computational Science Engineering 1 especially the kalman filter part..
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?
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.
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?
I'm assuming this is a 2nd year course, because concepts discussed would be adequately covered in freshman course 18.06 which should be a prerequisite for 18.085
yeah some schools like community college, some proffessors dont care, they purposely fail to teach well. Its easier to become a college professor at my school than teach at a high school. Its all self taught if you take physics, calculus or any other high level college courses.
you use the methods to discretely solve the system numerically. from there you essentially have data sets that can be further analyzed graphically (traditional plots, 3d plots, simulations, etc) by the nature of the question, I don't think u understand mathematical modelling
Oh and it's so funny when he said "I like to teach you, not to grade you" and "Don't worry about grades" all these other fail professors start every semester with talking about grades and how you should memorize things and focus only on grades. It's hilarious!
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.
+muad ali Actually no, these are different fields. Computational Science and Engineering (CSE) deals with solving the mathematical problems in Science and Engineering using the power of computers. The pillars of CSE are Numerical Mathematics, Scientific Computing and High Performance Computing. Some of the overlapping areas between CSE and Computer Science are High Performance Computing (like parallel computing, super computing etc), Visualization (Coputer Vision, Simulation), Algorithms (Parallel algorithms, Machine Learning, Big Data) etc.
