Lec 1 | MIT 6.042J Mathematics for Computer Science, Fall 2010

Nothing like procrastinating by watching a lecture from 12 years ago on a course I have no knowledge on

I'm commenting here, so that my grandchildren will think their grandad is a smart guy

when i see a professor ask his class ,have you ever seen a " for all " symbol, shows his dedication to make sure that every one  understand what he is teaching

The writing on the chalkboard and knowing i'm not paying for this class is so relaxing.

00:24 What's a proof? 02:02 How to ascertain truth? 07:30 What's a mathematical proof? 08:47 What's the definition of proposition? 09:50 What's '∀'? 10:10 What's a prime number? 10:43 What's predicate? 11:17 What's the universe of discourse? 11:29 What's quantifier? 16:27 What's "∃"? 28:45 What's "→"? 30:00 What's "↔"? 35:55 What's axiom? 40:34 What's consistency of axiom? 41:25 What's completeness of axiom?

I like this professor. He doesn't seem to put anyone down and looks to enjoy what he's doing.

These lectures are clear and comprehensible and you think to yourself, "I can do MIT". Then you read the recitations and homework assignments and realize why MIT is known to be so tough.

I want to sit in one of theses classes just to raise my hand and ask " When drawing a "4" should I leave the top of it open or closed?"

Thank you Professor Leighton. Your lectures got me an A in my Discrete Mathematics course.

It is a great pleasure to listen to this legend who is not only an extraordinary Math professor but also the co-founder of Akamai Technologies, a billion dollar company!! Regards from India!

What an amazing professor! seems fun and that 44 mins flew by so I can only imagine how quickly a 1 hour lecture would go. I'm a Computer Science major and I review these lectures on top of my studies I truly am thankful MIT makes these viewable.

What a great man is this teacher. All the teachings he gave are in the MIT Mathematics for CS book, but the interaction, the examples and the way he explains, are a good complement to the book.

He makes his lesson so easy to digest with interesting examples.

What a great teacher he is. What a level of dedication he has .

This first lecture is a fine introduction to logic, proofs in mathematics and number theory. All these topics are huge in mathematics. Professor Leighton introduces these topics for each computer science student to think theoretical and analytical about this class and beyond.

I'm in awe of these MIT OCW professors. They explain everything in such a coherent and understandable way. I love how they write their notes as they speak. If only any one of my professors were this good at their jobs, I'd be very happy.

I love this! Brings me back to my student days at Cornell from 1972 to 1977. Something comforting about that sound of a big piece of chalk on a slate board.

I am a senior high school student from Greece and just randomly stepped on one of the best "gems" I could find. This lecture indeed indicates how easy it is, but in reality difficult, to think and parallel everyday life with mathematics. It is really unique to see a very unconventional, for our country's educational standards, way of engaging mathematics in a more philosophical and applied manner than ever. I am truly glad to the man or woman that was assigned to list these lectures on Youtube, it is a really beautiful and entertaining way for me to spend my free time. I often listen to consults that by thinking that you will never attend any such classes in person or be able to study them abroad you are only limiting yourself and your dreams. So seeing these is a true way of forgetting my worries for my future studies in Applied mathematics. Thanks again to anyone from filming this and capturing audio to the professor and the man or woman who uploaded this unique playlist.

You know the lession is great when you can learn not only maths but even more things from it

Being a Sociology and Poli Sci student, the beginning really refreshes my view on math courses
