    "We just kept making books until they sold 0 copies and then we stopped" Sound strategy I respect this man.
  • Honestly I 100% agree with his approach of "I'm studying this because it's cool and we don't know how it works". Really that's the foundation of science.
  • As an Australian, I can tell you I've never seen one of these things before and find their existence fascinating.
  • @BILLY-px3hw
    I don know how this guys warmth hasn't melted every snowflake he has ever created
  • @RadenWA
    “Snowflake can be shaped like a bullet” Frozen 3 gonna take a pretty gangsta turn
  • This man spent his career studying snowflakes and he is happy, that's the life I want to live
  • Very interesting. As a brazilian, I grew up thinking the shapes of snowflakes were just a cartoon representation, until I traveled to Canada and was amazed by the real snowflakes. I loved watching them melting on my coat
  • one time i accidentally witnessed a perfectly symmetrical stellar dendrite, i was playing around with some snow a few years back, looked at my hand and boom, a perfect snowflake, and since that day i have fallen in love with the beauty of snowflakes and the way they form.

    "As a scientist, you want to figure something out." Contributing to the collective knowledge accumulated over millenia just because it's not already known. Badass.
  • @yourpalmal6018
    Listening to people talking about their life’s passion is my favorite thing ever
  • @limbridk
    We are lucky to have scientists like him, that give us the answers to how nature works. It's the most valuable thing.
  • The world needs more people like this guy who absolutely loves something as simple and complex as snowflakes...
  • @AcornFox
    When people call this guy a snowflake, he just says “oh my goodness, thank you!”
  • @Bravo.6
    "Does each snowflake in essence reveal its history through itsshape?" "Yeah absolutely, to some degree" That's a good pun, Dr.Ken!

    Few years ago I visited Hokkaido University and came to know they are the pioneer who discovered snow flakes patterns. We were so grateful to meet a local lady professor at the entrance and have her offer to guide us walked through the campus. During that time she posed me a question do I know how many shapes of snowflakes, my guessing was about five types. Now I know the better answer from this video. Thank you for this sharing!
  • @reubenpilli6549
    Understanding the formation of snowflakes - their shape and size - has a lot of practical applications. For example, different types of snowflakes have different coefficients of frictions when they are part of a snowpack layer on a mountain side. Such knowledge helps in understanding the conditions under which avalanches occur, therefore help in modelling and forecasting avalanches.
  • @AniketTurkel
    You can feel how much Ken likes learning about snowflakes from his face. He was enthusiastic from the start to the end of the video.
  • @kimberlee9608
    That man is the embodiment of: “Do what you love and you’ll never work a day in your life”
  • @TReXcuRRy
    I was shocked but the ending. Never have I asked myself during this whole amazing snowflake documentary why is this scientist researching this topic. It feels so naturally compelling to me to be deeply attracted to solving the mysteries of life and the universe. Questions lie in every topic and their answers are interconnected, understanding one topic will better your understanding of the whole. It would be sad if human beings only directly seek to increase their comfort and safety... Which we do a lot already.
  • @mickeyp6639
    I love his comment on the saying "no two snowflakes are alike" because yea he's right most things with really any degree of complexity in nature are going to be differing in some way
