I just saw Mr Khan on Colbert show, and am discovering the videos wow ! TY so much for your work ! On that interview , the fact that your not an educator was received negatively. Anyone with 1/2 a brain can see that your work is the ultimate teachers tool, instead the audience's political bias was offended that you can do as well as pros on the subjects you are trained in. As if Plato and his students all had teaching certificates , and that's why people listened to what they had to teach.
Best and the most humble Teacher ever.... agreed with roshid people who dislike you Sal are simply retarded perhaps they are those school teacher who realize that student now will be more confident in class... and they will loose the oppurtunity to make them look like fool
i visited your site ,and its " cool " but where are the computer tutorials? or programing tutorials? and why dont you upload some videos of "others lectures" on your site
i mean its for knowledge right? some vids of the university of MIT or Standford or some other lectures on the web
This is amazing. I am so excited this exists! Now I am going to be able to learn these basic concepts on my own without the prep classes I can't really afford. Now I can just take the classes I REALLY need and not waste money on the basics! Thank you so much!!
I have a friend who has taken lessons from Khan Academy for about a year or so. Actually he is my classmate. We are attending a 2nd high school grade in Croatia (I don't know how things with school work at other places in the world), and all i wan't to say that the guy is crazy. He does quantum physics and stuff that require so much math that it's almost impossible to belive he really does that.
Can you guess where he's learned all that math? :)
This is indeed awesome. Shame I don't know anything so great for learning Spanish for free. Everything from math to computer science to science comes naturally to me, but I'm dreadful at Spanish.
yea this man is an angel, he literaly taught me in a hour what it took a me a week to do by teaching myself through books, I went from pre algebra to Calculus in a few months, and am about to start phyics. the thing that I believe seperates him from every other tutor is that he not only teaches you how to do the problem but teaches you WHY your able to do that way which gives a greater understanding and appreciation of the beautry of math and physics,
Hi Sal, i think ur awesome, great sense of humor, you make learning fun, you have a great gift and i commend u for sharing it, im glad to have stumbled upon your website, i feel more confident in taking gmat now , laid off after 10 years of calculating NAVs @MS, so grad school then CPA, hopefully u will have CPA videos soon too, well anyway, best wishes, beautiful son and loved ur CNN video, what your doing now is more rewarding than working in a hedgefund, u deserve $millions in donations ;-)
your website looks as good as the you tubes and e-bay web sites so they are easy tonavigate around. which paint application do you use please sal? i do'nt get any useful writing tool with my basic paint!
Sal, As you already know I've sent over a thousand kids, parents and teachers to your You Tube channel. I had told them that this video is up on your site but I didn't realize that you took this off your You Tube page. Can you put this back up along side with video request video? It's a very good video of explaining your website. Thanks guy.
I am trying for my Six Sigma Black belt, was going through YouTube, found you, you are awesome. Your teaching style reminds me of my late father, who used to teach the step by step logical way. Even if it is longer, you can never forget.
Sir, Hats off to you, I am very glad to found you. Next on my skills level up is Basic technical Math exams, i am sure, if I go through your lessons, I will surely pass.
The problem is the banks didn't really risk anything. The big boys like Goldman Sacs just pushed out the ones they didn't want and bailed out the others. The borrower is the one that loses out - no house, no job, equity (earned) destroyed. The banks? they just lend more money into exisistence, what do they care?
Sal, you are the BEST. You're such an amazing instructor. I love how you teach. You make difficult problems really easy. Now to have a brown nose, but I love watching your calc, trig, and later linear algebra, and diff. equations, so if you would, maybe post a few more of the last 2 I mentioned. I try looking on youtube for other instructors, but you are by far the best. Thanks for dedicating your time to these videos.
I am a high school math teacher and often refer my students to your videos when they need extra help outside of the classroom. Many students cannot afford a traditional math tutor, but with your videos they get one!
Your work is Godsend !Thank you. I was hoping you could post a video on Laplace transform for step and delta functions and their application, please. Thank you man.
I sometimes do not understand how people just put in all their effort for publishing their help for absolutely free!? However I can give them all (especially you) my best prayers that may God pay you back all your efforts you do for the general public.
Great idea but I really don't want to go through basic addition/subtraction/multiplication/division and the rest to get to the precalculus/calculus topics that I'd like to review.
"Geometric Dimensioning and Tolerancing for Mechanical Design"
for her work.
She just bought an $80 used book on it. The table of contents is intimidating. It's seems like it's kind of a specialized subject. So if you're running out of subjects to do videos on maybe you could do something on this. It looks challenging to me.
You're the man Sal and I can't tell you the number of students I've sent to your website. Actually you are the number one topic of conversation as the parents and the kids come back to see me. Everyone is simply amazed at all the work you have put into this. You are Nobel Prize material. Thank you again for making a difference for the world.
I second that -- I've told at least 15 people about khanacademy, and everybody agrees it's the most amazing educational resource in the world and at least a 100 times better than our teachers.
Given the way Sal explains it and nature of the YouTube videos, I don't think I've ever had difficulty understanding anything he has ever explained -- pretty amazing to think about given that it's a difficulty most teachers have.
Ten more CNN appearances, and I think Sal will be on his way to Sweden!

89 years from now Sal will have in his posession:
*Nobel Peace Prize for educating those in impoverished countries.
*Time Man of the Century, for revolutionising methods of education.
*Congressional Medal of Honour, for raping the US education system.
And all these will inspire him while he continues to make videos at age 125.
