Mahmood Hasan Hahaha perfect quote

Sorry Bob Dylan first.

Yeah..but Nobel for what exactly?...In that case he should get it for Physics, Chemistry,Peace, Medicine and ofcourse Abel prize for Math.

agree he really changed the world, I went back to school, college, and I graduated with honors...how, khan academy!!! Guy needs to be worldwide!!! humanity will be sooo much better!!! he needs to get the noble prize !!!

Agreed 100%, I've been saying this for years!

LMAO

Would have put a sarcastic punchline here. Then I saw Gizelle Blanc's comment. (He can totally...) Put mine to shame.

I'm 32 and still listen to his videos while I work. I get educated as a hobby!

@@rolandomarinhdez8262 good one!

I agree with you, but one problem.........Some people hate Learning....!

+LOMES art class video resources or, some people don't want to be taught. Not to sound narcissistic but look at all those middle school students hating every minute there

+LOMES art class video resources I disagree some people don't like learning. But it depends on the subject. Person x may hate learning math but he loves learning about art.

+zvartnost u're dense... that's probably why

Dopa44 I understand everything my teachers say when trying to explain something but Mr. Kahn just does a better job imo

Khan is a genius though. It's not really surprising. It's unfair to expect your teachers to be as capable as him.

Exactly Teachers do not teach as good as Khan

I also go to a pretty good school. The only teacher that teaches better than Khan has 4 PhD's.

Cosmic kitty Me too!

That's beautiful. Khan Academy has made life better for all of us.

He is my favorite teacher

follow for follow !

Its nice to be able to pause the video or replay a section and to hear a statement again. Its easier to make connections! He is so helpful!

+Aldora LaPlume That's great. The most important thing when it comes to math is to learn stuff in he right order, and always make sure that everything is crystal clear. I would say that Arithmetic/Algebra/Geometry, in that order, are probably the fundamental subjects, and this will take you really far.

*****​​ It's also important to develop a good intuition for things, so that you don't rely too much on formulas. One example is the cosine formula for triangles - it is pretty easy to derive that formula from scratch by splitting an arbitrary triangle into two right triangles, and then comparing their respective sides and angles and finally combining them so that the cosine of one angle only depends on the sides of the original triangle.

***** Indeed. However, it might sometimes be more practical to start with simply presenting a formula if it has a complicated derivation, so that the students at least can start using it. For example, the area of a circle pretty much requires calculus to be derived properly, since you will have to do something like taking the integral of the areas for an infinite number of rings of greater and greater radius - for example, you could say that one ring has the area 2·π·r·dr and then integrate this from 0 to R, which will result in the area of the circle --- π·R². This would be straightforward if you have some knowledge of integral calculus, but it might be too complicated for people who are just starting out with Geometry and most likely at that point have knowledge of Arithmetic and Algebra, although they could probably understand the general ideas.

@@Peter_1986 wont you shut UP

I love this comment

NianTube0 I just saw this and was like OHHH MAN I COULD NOT THINK OF THIS

LamborGENIE he should totally use that on his website. the Khancept of Khan

+Mahmood Hasan We'll get there one day!

It was probably your teacher who was hopeless, then. Good teachers can teach things to anyone, because they know how to reach out to every student. Some teachers have this annoying attitude that they almost seem upset when a student asks questions that "are obvious", and that's exactly the kind of attitude that intimidates people to ask questions in the first place. If a student is unsure of something, then he or she should always feel comfortable to ask about it, and NEVER feel "hopeless".

Agreed I started teaching and saw massive growth in students. I always believed in making classes open for dialogue and laughter. Took an IT class from an average of 20% to an all out class average of 75% in less than a month. I was called in to help them pass their final exams. Teachers need to understand that it not only takes loving your job, it takes loving your students.

Exactly, and I'm glad to hear that. Actually caring for the students makes an incredible difference, and makes the whole climate much more friendly and welcoming. Of course, the courses should be taken seriously and sometimes need to be formal, since you often need to use formal language to clearly explain how math and science works - but there is nothing that says this should exclude a relaxed teaching style and a sense of humour. One lecturer that I have a lot of respect for is professor Gilbert Strang from MIT, he is a good example of how I think teachers and professors should behave during a lecture.

Sciba Trista For now I think it's better for students to use it as home to learn a concept better if their teacher didn't explain it well enough (high school)

khan academy doesn't have enough exercises to really master hard concepts for most people

Noooooooooo I lost my virginity!!!!!!!!!!!!'

This is the future of education.

I would like to add that the instructers at the GED class do not know what to do to help Adults. I was so frustrated. I cant afford the expensive online courses. I wouldnt be able to get my GED if it wasnt for this. I am going to take the test in the next week. I am so grateful to you Sal!

Oh I forgot to say that this is not easy for me. I dropped out of the 8th grade in 1986. Thank you Sal. If I had to pay for this. I would never get my GED. I can not express how blessed the world is now that you have given us all this gift.
