We think humans have created huge amounts of information. But in fact, it's a tiny amount compared to the information needed to describe the universe. Using beautiful slow-motion footage of a water droplet, presenter Jim Al-Khalili gives us a sense of just how much of what goes on in the physical world is hidden from us.

    Professor Jim Al Khalili is a world-class instructor and this is one of my favorite educational videos on YT.
  • I've lost count of how many times I've viewed Prof. Al Khalili's science documentaries. These shows have no peer.

    34:57 “[Alan] Turing’s brilliant mind saw that any calculation had two aspects: the data and the instructions for what to do with the data.” It’s actually fascinating that it took until the mid-1950s for someone to come up with that abstract idea since Joseph Marie Jacquard’s punch cards, demonstrated in 1801—so, exactly a century and a half earlier—worked on essentially the same principle.
  • I can't believe the human is so brilliant and so dummy in the same time. A beautiful documentary, thank you.
  • Irving Finkel! Brilliant Academic, The Expert on Cuneiform Tablets. Curator at the British Museum. I adore that man, and his stellar witt!
  • His selection of images is informative and dovetails with the elementary dialogue.
  • @RC-uo3ds
    I just love the way information is shared by professor Jim Al Khalili , one of my favourite physicist .... wish one day meet him very soon
  • It is the first time I heard of the demon's analogy in keeping record of 'states' of molecules. This shows how history is important in understanding the origin of 'concepts' developed by scientists!
  • 50:00 Its was worth the cost of the TV Licence just for the water drop slow mo footage !

    Corruption is the biggest threat to freedom and prosperity. Let's vote against corruption!

    Every event, no matter how modest, Is a wealth of information.
  • @bafflezbiz
    Jim already has a slew of these, but I wish he developed videos detailing the history and depths of every corner of human knowledge. These should be required viewing for every person on the planet.
  • @Aljoheri
    Everything here is beautiful. But I am commenting on this right after the intro to THANK THE SOUNDTRACK COMPOSER. I love it.
  • @ouimetco
    The analogy from the jacquard weave to modern computers is startling! Startling.
  • Mind-blowing! This is the most amazing series of bits I have ever encountered! Filled many of the holes in my brain and will inspire me going forward. God knows, there is beauty, structure and order to build! 🥰

    All of this is, to a great extent, already contained in the theory of hylomorphism. Over 2,000 years ago, Aristotle said that all that there is in the universe is a compound of matter (hyle) and form (morphe). Matter is informed and that’s the only way it actually is real. Reality is hylomorphic. And as a bonus, another way to name form is by a Greek word that will be familiar to you: energeia.

    Irving Finkle must walk around interpreting and translating things and objects that we take for granted every day. What a fascinating man, I hope to visit his museum some day.

    I've not read all of the comments of course. But, when thinking of Maxwell's demon, there is an obvious expenditure of energy to me. He opens a portal to allow the atom to cross. He has to expend some energy in some sort of way to open and close the portal. Probably much more than the atom uses to glide through the opening. I know it's just a thought experiment. But the conversations about such things is what makes it so great.
