| Huge Sanderson fan and thought the video was excellent
|
| Also a huge Dali fan and like to think Salvador would have been
| delighted by Grant calling his self portrait 'a weird/strange
| monster creature'

| Still impressed every time how well Sanderson is able to use his
| visualization and presentation skills to make explanations so
| good.

| Came here to make much the same comment. I cannot tell you how
| many videos of his I have watched regarding complex
| mathematical subjects which are well beyond me, yet still he
| allowed me to walk away with a reasonable understanding. His
| clear explanations coupled with impressive visualizations make
| for a powerful learning experience.
|
| Particularly at a time when so much education is online,
| Sanderson is the gold standard for teaching IMHO.

| This man deserves so much respect. He even open-sourced the

|
| I'm sure a lot more kids would be interested in math if they were
| able to visualize the beauty of it in a more vivid manner than
| just chalkboard drawings.

| And one more reason why the phrase "Those who can, do. Those

|
| Just think of the number of people who who have learned from
| his videos and have used it gain a deeper understanding, been
| inspired to learn more, or used it to go and do to exciting
| things.
|
| The amount of impact he has had by effective and concisely
| explaining complex topics is incredible.

| This is probably posted because there was a JavaScript seam

|
| I think one of the interesting things about this demo being in
| Julia was that Julia was chosen for this "Introduction to
| Computational Thinking"-course over Python, because Python is too
| slow to do seam carving (and presumably it's too cumbersome to
| bend numpy to do it as well - at least I couldn't come up with a
| solution that didn't require several loops)

| This presentation is so good. It really helps you appreciate how
| wide the gap is between mediocre and excellent instruction. This
| video explains in 30 minutes that took years of classes in
| computer vision for me to grasp at an intuitive level.
| Convolution, gradient, energy based models, dynamic programming.
| Grant is a national treasure.

| For all the negativity that modern internet has brought, we
| forget that a poor Indian kid with a cheap smartphone can watch
| Stanford lectures on astrophysics. Just think how crazy this
| was even 20 or 30 years ago! Anyone with an internet connection
| has access to more books than she could ever read in a
| lifetime, lectures and videos from the best learning
| institutions and the best teachers in the world (such as 3b1b),
| they can ask questions to knowledgeable people and fellow
| students... Magical, for millenia this was inconceivable.
