    Can we just say that Nova and PBS are probably the best things happening in the USA at this moment?!?!
  • I've always loved Nova since I was a kid. Having been raised in a lot less than ideal circumstances and family setting. This documentary just helped me to realize my poor self perception is not real, as well as break away from my childhood trauma, which I still carried to this day. I believe having this knowledge will help me to eventually overcome this childhood trauma by erasing my current image of poor self perception. Now I feel I will be able to put away those bad memories and therefore begin to discover who I really am and become consciously happy and find happiness. Thank you, everyone, at Nova.
  • 35 years ago, I sustained a traumatic brain injury that has affected every aspect of my life since. My cognitive function was only slightly affected--i had received special schooling since 3rd grade when I entered the program for gifted students; since my brain was already accustomed to finding alternate paths, it didn't have too much trouble when there was a landslide over the "usual" way of thinking. My memory, however, was basically destroyed. Some things I remember clearly, some things are simply missing, and I can prove with documentation that some things never happened outside of my own skull. The discussion about memory as it relates to perception interests me deeply!
  • @rachelore
    Loving the idea that our reality is completely dependent on what we detect, expect, and remember. Yet more proof of the power of the mindset. Detect, expect, and remember great things and then that becomes your reality.
  • Once there was a Mystical tree with an abundance of leaves. One leaf says to another leaf, " I'm so very afraid. It's getting colder and if the temperature keeps plummeting we will all surely die." The other leaf says to the scared leaf,"Can't you see! You're not afraid because you're going to die, you're afraid because you've mistaken your stem for your roots. You're actually rooted much deeper than you believe."
  • Can we finally start being more charitable towards each other now? I’ve been aware of this phenomena for abt a year and it has helped avoid arguments by just simply understanding that no one sees the world exactly the same as me. And that’s ok.
  • @BeyondBorders00
    I have a grad degree in neuroscience and I'm really impressed with how well made this documentary is! Reminds me of why I choose to study neuroscience in the first place!
  • @peaceofpiety
    My grandparents didn't have cable, so when I stayed with them I had healthier options like exploring outdoors, or watcing shows on PBS like Nova. I've always been fascinated by learning bigger things than what was taught in schools. Science is an art of extraordinary intelligence. Since energy is the Source of all, it seems logical to desire to understand the way the mind works with such facets of art. Much graditude for PBS and Nova for helping us to expand consciousness. Keep moving forward; progress! ⚡ 🧠
  • @bocanjm215
    I love when new NOVA videos are released. I actually learn interesting information, instead of being bombarded with political videos.
  • @whimsical913
    Wow, this documentary is absolutely mind-blowing! Nova has left me in a state of intellectual awe yet again!!!
  • @BrownSquid053
    Thank the heavens we still have educational channels like this🙏🏽
  • @ej12349
    My first exposure to NOVA was in Jr. High School Science class back in the late 1970's. Our teacher would often show NOVA films on Fridays. Then, I would watch NOVA on PBS. Love NOVA!!
  • @victor9
    Im glad to be alive in this era of information and technology. So much interesting stuff around us at all times
  • @Josh-oe4ex
    GOD i love NOVA. I remember as a kid on a farm, we had one massive Magnavox Console TV and there was never anything on that, but my parents would let us watch PBS of course(there were 5 channels) and I do remember NOVA. That must've been literally over 30 years ago. 34 yrs? Man, sure glad that PBS and NOVA are still keeping the flame lit for us curious ones. Only half way in and some notions i had learned about visual processing back in school have been usurped/adjusted. That is so cool to see things evolve and become more accurate. The color thing really got me. Also, how similar our brain is to a digital computing device is remarkable. Thanks to those who put their time and effort into these shows
  • @0ptimal
    Loved it. This topic is for me up there with the most interesting things in existence. Perception and the constructing of personal reality is endlessly fascinating. Part of that is the fact that perception is so malleable. So we have this fundamental layer of being that is essentially programmable, if we choose. Or we can operate on default like most of us do and let our perception be shaped unconsciously, and externally. Screens are good at that, its why its good to be intentional about what media content we consume. I've rambled enough.
  • Thank you to that lady who’s doing the experiment and allowing these people to analyze her I think her effort might help others
  • @JohnDoe-jh5yr
    We're augmentating our reality with technology without realizing how augmented perception already is.
  • I love these explorations of the mind. They have taught me not to take myself too seriously, and to not be didactic in my opinions. I'm making up from whole cloth a lot of the things I believe, and misinterpreting the rest.
  • @noisetheorem
    As a neurodivergent person with diagnosed symptoms, I appreciate your analysis. I struggled with “being different” in childhood, but as an adult I found ways to use the hyper focus to my advantage. I also work for a company full of Germans. I agree. You’re not autistic, you’re just German.
  • @chrisprescott2273
    Growing up I've always loved NOVA. It's good to see it, and PBS still going strong after all these years.
