    The little girl at the start knows more about computer than most people at my job
  • @AnindyaMahajan
    The 6 year old girl has a really bright future ahead of her. She solved the peanut butter challenge better than most adults do when they first take David's CS50 course!
  • @9009matorres
    Dude’s child explanation was more complicated than my junior and senior students can even understand and the little girl looked genuinely intrigued.
  • @hebalon
    I think the little girl at the beginning has a better understanding of what an algorithm is than many journalists writing about algorithms. Her explanation was amazing. Simple but absolutely correct.
  • @felipellrocha
    As a software engineer, that little girl is a genius. She killed it!
  • David Malan is not only a fantastic teacher, but at L4 and L5 he lets the grad student and expert do the explaining while he listens. There is a lot of humility there for someone so smart.
  • @SamKrahl
    This is a stunning example of how to be a good educator. Fantastic job Prof. Malan!
  • David is one of the best teachers for programming. He understands what students don’t understand and uses real world analogy’s in the best way.
  • @tanukitom8606
    I took Dr. Malan's CS50 course last year. God bless this gentlemen for providing excellent knowledge to the public. I even started to be more articulate just because the way he talks lol.
  • It is amazing that a 6-year-old can explain what algorithm is even better than an adult.
  • The graduate student is my brother. Let us wish for him a bright future. Thank you! Best wishes, vaia! @mahi
  • @bellatadson
    Can we acknowledge how brilliant that little girl was?! So precious! <3
  • @clauseland9005
    DAVID MALAAAAAAAN. Man after I took CS50 I have been a huge fan. Why isn't every teacher so engaging as David. Thank you for being "dumb" so us as students don't have to feel stupid. You are the best David
  • @ashmac87
    I love how this guy explains things without judgment! So many people are condescending when they know things.
  • @FelipeFreitasFS
    Half of yellow pages sales are to Malan, just so he can rip it apart at every algorithms class. Gotta love this passion!
  • @zurgmuckerberg
    I'm currently at hour 4 of David Malan's CS50 courses I watch online, and I can say, he's the best teacher I've ever seen.
  • @Aztari0
    this man must have torn up half of the existing phonebooks at this point
  • @1sava
    How does a 6 year old even know what an algorithm is? 🤯🤯🤯 She is brilliant!!! Kudos to her parents!
  • @LivvieLynn
    Now teach my coworkers how to use excel.
  • @MeroGrumble
    David's adaptation to the various levels was nice. Instead of monopolizing the floor, he was really leading different levels of interviews and gave enough space for the people to express their knowledge in a way that felt natural and instructive.
