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.

Thank the heavens we still have educational channels like this🙏🏽

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!!

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

If only more people took time to watch things like this. Well done PBS, enjoyable education.

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!

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!

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.

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."

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! ⚡ 🧠

[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.

[whimsical]

Wow, this documentary is absolutely mind-blowing! Nova has left me in a state of intellectual awe yet again!!!

[JohnDoe-jhyr]

We're augmentating our reality with technology without realizing how augmented perception already is.

Growing up I've always loved NOVA. It's good to see it, and PBS still going strong after all these years.

[MrWaterbugdesign]

I've studied/thought about how brains work for 25 years. "Thought" is actually very simple. If someone touches you with something very cold you jump back. We totally understand how a nerve works. That's all a neuron is, a nerve. Without seeing what the cold object was we have a good idea of its size and texture because a bunch of nerves all fired in some sequence that we "remember" being a pattern. The object felt sharp or dull because we "remember" what that sequence of nerve responses would be. What's unique about neurons us how they make collections to trigger a thought. Just as the cold object caused a "feeling" of cold, neuron configurations create the exact same "feeling" of a thought. That's what a thought is. We have strong thoughts and weak thoughts. Many, all the time. Just as our skin has all kinds and levels of feelings all the time. We only pay attention to the stronger feelings (thoughts). People eve say it..."I feel like...."

Im glad to be alive in this era of information and technology. So much interesting stuff around us at all times

[bocanjm]

I love when new NOVA videos are released. I actually learn interesting information, instead of being bombarded with political videos.

[erichodge]

Ok...I was going to watch this while folding clothes, but this is too amazing not to concentrate on.

My faith in Youtube is restored when I watch documentaries like this.😍
