    The Fibonacci Sequence is so important and Hank is such an awesome presenter and this was just not his best day. I would love, LOVE it if this were re-done. For a random video it would not be worth it but this is something really accessible that unlocks SO MUCH else about nature

    Today I learned that Leonardo Fibonacci just used the rabbit illustration as an example problem to answer in his book that was about introducing arabic arithmetic to italian merchants. Not as a pattern in nature. Like at the end of a math chapter it has little problems that, if you can answer, you've got the gist of the chapter. Also, fibonacci wasn't his name... it was given to him by a historian guillaume libri in 1838 and that wasn't even the name he gave him. Filius Bonnaci was the name which means son of bonnaci. All my life i've been lied to!

      thank you for proving my sent me to a biased reference. Your not getting it...we are not just talking about bees but bees that levitate for miles away from the hive, load up 90% of body weight with pollen, then levitate back miles to the hive in a straight line around 30 mph with no drop in speed regardless of load...they are not flying. Levity is stronger than gravity and it exist in creation everywhere. All you are doing is proving that you stick within fixed circles of thought....this was my original point when I said you stay in school and do nothing else. And in response to your query regarding the universe being created with was. Again you prove the creationist point..thank you.

    • macsnafu

      Or maybe this article will more directly address your bee comments:

    • macsnafu
      macsnafu 1 year ago

      No, it's not clear that the universe was created by math. If the universe can be described by words, does it automatically follow that it was created with words, or that words are the universe's true form? Geez, type a line or two, and suddenly someone thinks they know everything about you. I certainly had no idea you were a creationist from the comment you posted. And by the way, scientists finally have figured out how bees fly, and, BIG SURPRISE, it doesn't violated the laws of physics. Here, for example, is an article from 2006 talking about it. Don't like that article? Do a Google search; there's plenty of others. Now I'm sorry I gave your comment a thumbs up.

    Nature cannot make anything!
    To make something requires intelligence. So unless nature is a thinking and reasoning being, then nature did not make mathematics or the sequence.

    However, if the sequence was made, it was made by a thinking and reasoning being, we might call it God.

  • Sanjit Suresh
    Sanjit Suresh 1 year ago

    When you said that you get the same number when dividing almost all two successive Fibonacci numbers (1.55), I was a bit confused because I always thought that you never get the same number as the ratio- it approaches the golden ratio as the numbers in the Fibonacci sequence get infinitely large? I think I get what you mean because they become very similar when the Fibonacci numbers you use get very big, but their not the same, right?

    probably first and probably last time commenting on Youtube :) :
    After years of watching CrashCourse i decided to watch this math video and i see this guy and think "lol is this john green? looks like him but i feel its not" so i check out the comments to find out the name of this guy cause i've seen him in CrashCourse but i just blanked and couldn't come to terms with it. found out its hank green. searched him. found out his brother is john green. my world is complete. Life makes sense. (no wonder he looks the same but different in crash course videos.)

    what i learned the most from this video : hank and john are brothers and more than 1 green exists and hank lives in montana and the Fibonacci sequence was made 1300 years ago in India.

    I hope that one day you too can solve life and feel wholeheartedly complete with a simple math video - 3 min 19 sec of your life.

      My last comment on this thread. Evolution cannot be demonstrated with empirical evidence making it scientific theory not fact. When I say evolution, I am referring to macro evolution where a species actually becomes another or changes types.

    • Gary a
      Gary a 1 year ago

      +Ian B Even the pope accepts evolution as fact, because it is a known fact (unless of course you live in some parts of America or West Asia)
      The Big Bang defines (in science) 'the initial inflation of the universe'.
      Understanding either of those things doesn't require any faith at all.

      Also, you misread. I didn't say 'one could easily accept either theory', nor did i mention anything about the origin of life. I said reinterpreting things to be compatible with your own predetermined beliefs doesn't make your beliefs true. As you have demonstrated.

    • Ian B
      Ian B 1 year ago

      In response to your last paragraph, I agree that one could easily accept either theory of the origin of life. Nor evolution/big-bang theory nor the existence of God can be proven according to scientific standards for validation. Both require some level of faith to believe one or the other ;)

    'Math was invented by a little something called Nature' said this man.
    "Nature" an unintelligent nonliving imagined mother nature... that does not do anything, doesn't manage anything, but Nature follows the established laws, governed often by electromagnetic forces, but other fundamental forces as well in nature.

    The infinitely intelligent being created things like this to point us to him... but we choose our response. This is His goal, to reveal what is in our hearts.

    Romans 1:19 since what may be known about God is plain to them, because God has made it plain to them. 20 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.

    21 For although they knew God,
    they neither honored him as God
    nor gave thanks to him...
