If you have practical questions you can ask Stefan Kirschnick, he made the German dub. https://www.linkedin.com/in/stefankirschnick/

It’s a question that's been pondered for centuries. It's such an obvious question, in fact, that it barely even seems worth asking anymore. But it is worth asking! And the answer is actually pretty interesting. So let's get into it!
The quick and simple answer is that blood absorbs green light and reflects red light. As a result, it appears red to your eye.
This means that the reason why the blood looks red is because of how light is reflected through our body!

Blood is red because of hemoglobin, a protein molecule that contains iron. When the oxygen in your blood comes in contact with this iron and binds to it, it gives off a reddish color.
Hemoglobin helps transport oxygen throughout the body through arteries and veins. Hemoglobin is what gives blood its dark red color. Red light can't pass through a water molecule because of its electric charge, but green light can: it reflects off the surface of water molecules instead of being absorbed by them. That’s why if you’ve ever dived down deep in the sea, you’ll notice that reds quickly disappear, but greens can still be seen clearly.
The amount of red light can change with temperature too though.
Hemoglobin absorbs light energy (also known as photons) and converts it into heat energy instead. When there's more hemoglobin present than necessary, those extra photons are absorbed by free electrons in other molecules within our cells; this leads to higher temperatures and eventually causes overheating if conditions get too extreme (like on hot summer days). On the flip side, when there isn't enough hemoglobin available for this process due to insufficient oxygen levels or injuries like cuts from sharp objects like knives--it results in a blue discoloration because not enough light is getting through due an absence or deficiency of iron-containing proteins such as myoglobin.

So next time you hear someone tell you that blood is actually blue when it doesn’t have enough oxygen, you can tell them that they’re wrong, and that the blood is always red, but that the colour we see depends on a number of factors, including how much hemoglobin there is in the blood, how much light there is, the colour of the light, and even the temperature.

Neuroanatomist Dr. Jill Bolte Taylor explains the 4 key ”characters” of the brain, and how understanding each can expand your perception of yourself, and the world, forever.




At age 37, neuroanatomist Dr. Jill Bolte Taylor suffered a stroke that would take her eight years to fully recover from. This is how it changed her understanding of the brain.

In this interview, Dr. Jill draws a map of the human brain, explaining how it is comprised of four distinct modules, each serving a unique role in function and personality. This combination of cognitive and emotional components gives rise to the multidimensional characters within each of us.

Are you looking to be more rational, more creative, more forgiving, or perhaps less rigid in your thinking? Dr. Jill suggests that by becoming aware of the four modules of our brains, we can consciously choose to engage specific parts. This awareness allows us to harness the true power of our brains and shape who we want to become, ultimately fostering less anxiety, more inner peace, and a vastly more purposeful life.

----------------------------------------------------------------------------------

About Dr. Jill Bolte Taylor:

Dr. Jill Bolte Taylor is a Harvard-trained and published neuroscientist. In 1996 she experienced a severe hemorrhage (AVM) in the left hemisphere of her brain causing her to lose the ability to walk, talk, read, write, or recall any of her life. Her memoir, My Stroke of Insight, documenting her experience with stroke and eight-year recovery, spent 63 weeks on the New York Times nonfiction bestseller list and is still routinely the #1 book in the category Stroke in the Amazon marketplace.

Dr. Jill is a dynamic teacher and public speaker who loves educating all age groups, academic levels, as well as corporations and not-for-profit organizations about the beauty of our human brain. She focuses on how we can activate the power of our neuroplasticity to not only recover from neurological trauma, but how we can purposely choose to live a more flexible, resilient, and satisfying life.

In 2008 Dr. Jill gave the first TED talk that ever went viral on the Internet, which now has well over 27.5 million views. Also in 2008, Dr. Jill was chosen as one of Time magazine’s “100 Most Influential People in the World” and was the premiere guest on Oprah Winfrey’s “Soul Series” webcast. Her new book, Whole Brain Living – the Anatomy of Choice and the Four Characters That Drive Our Life is a #1 release on Amazon in categories ranging from Neuroscience to Nervous System Diseases and Stroke.

Join Big Think Edge for exclusive videos: https://bigth.ink/Edge
----------------------------------------------------------------------------------
OVERVIEW:

In a profoundly informative and deeply optimistic discussion, Professor Michio Kaku delivers a glimpse of where science will take us in the next hundred years, as warp drives, teleportation, inter-dimensional wormholes, and even time travel converge with our scientific understanding of physical reality. While firing up our imaginations about the future, he also presents a succinct history of physics to the present.
----------------------------------------------------------------------------------
MICHIO KAKU:

Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study as well as New York University (NYU).
----------------------------------------------------------------------------------
TRANSCRIPT:

My name is Professor Michio Kaku. I’m a professor of theoretical physics at the City University of New York and I specialize in something called string theory. I’m a physicist.
Some people ask me the question, “What has physics done for me lately? I mean, do I get better color television, do I get better internet reception with physics?” And the answer is yes. You see, physics is at the very foundation of matter and energy. We physicists invented the laser beam, we invented the transistor. We helped to create the first computer. We helped to construct the internet. We wrote the World Wide Web. In addition, we also helped to invent television, radio, radar, microwaves, not to mention MRI scans, PET scans, x-rays. In other words, almost everything you see in your living room, almost everything you see in a modern hospital, at some point or other, can be traced to a physicist.

Now, I got interested in physics when I was a child. When I was a child of eight, something happened to me that changed my life and I wanted to be part of this grand search for a theory of everything. When I was eight, a great scientist had just died. I still remember my elementary school teacher coming into the...

How Big is The Universe?

We begin at the familiar blue and green orb we call home and zoom out to explore the vastness of space. From the Moon, our closest cosmic neighbor, to the edges of the observable universe, prepare to be astonished by the sheer scale of everything that exists.

Travel with us as we venture past the Moon, understanding its distance in terms we can grasp. Witness the Sun, not just as a source of light, but as a milestone in the vastness of our solar system. We don't stop there; Mars, Neptune, and the outer reaches of our solar neighborhood await.

Discover the awe-inspiring distances to the Voyager 1 probe, the enigmatic Oort Cloud, and the neighboring star system of Alpha Centauri. As we sail through the Milky Way, understand our position in the grand scheme of things, where our entire history is just a whisper in the cosmic wind.

Our voyage takes us further, to the Local Group, Virgo Supercluster, and the staggering Laniakea Supercluster. We contemplate the Great Attractor's pull and our place in this immense heaven.

Confront the boundaries of the observable universe and ponder the mystery of what lies beyond. This video is not just a journey through space but a journey of perspective. Join us in marveling at the universe's grandeur and our humble place within it.

You can sign up for a paid subscription to my newsletter and YouTube channel here - https://www.distilled.earth/In this video we cover enhanced geothermal and the role it could play in decarbonizing the world's electric grid.Recently there have been a series of breakthroughs in enhanced geothermal systems, an advanced method of generating electricity from the Earth’s heat. If these developments continue, geothermal could generate between 10 and 20 percent of the country’s electricity in the coming decades, according to recent studies from the Department of Energy and Princeton.Enhanced geothermal could also solve one of clean energy’s biggest problems: intermittency. Unlike solar and wind, geothermal power plants can operate at all hours of the day, no matter the weather or time of year. In this story, I’ll cover the past, present, and future of enhanced geothermal and look at what needs to happen in order for the technology to play a large role in decarbonizing America’s power sector.All sources can be found in my article on the same topic here: https://www.distilled.earth/p/....the-new-clean-energy #technology #sustainability #geothermal #energy

Mercedes-Benz is one of the oldest and most luxurious car companies in the world, worth around 80 billion dollars. But being among the most desired and expensive cars today, it’s easy to forget its early humble beginnings.
It all started with a poor engineer, who faced many doubts, hates and failures in his pursuit of building the first horseless carriage. In spite of that, he proved everyone wrong and turned his small venture into the world's first and biggest production car company during the 1890s and early 1900s.
But what started as an inspiring success story, took a surprisingly dark turn, when the company profited from supplying military vehicles to the Nazis under the works of forced labors.
So well, sit back and relax, today we’ll be covering the insane story of Mercedes-Benz, and the man who brought automobiles to life, Karl Benz.

In the 1600s, the Dutch East India Company employed hundreds of ships to trade goods around the globe. In order to fund their voyages, the company turned to private citizens to invest money to support trips in exchange for a share of the profits. In doing so, they unknowingly invented the world’s first stock market. So how do companies and investors use the market today? Oliver Elfenbaum explains.
