ALL OF PHYSICS in 14 Minutes: https://youtu.be/ZAqIoDhornk

Everything is made of atoms. Chemistry is the study of how they interact, and is known to be confusing, difficult, complicated...let's learn General Chemistry in under 20 Minutes.

This is not ALL of Chemistry, as fields like "Organic Chemistry" deserve videos of their own. But, this is the foundation, or "General Chemistry", which contains most concepts you need to know to understand other topics and fields of Chemistry.

This is a summary and revision of around 4 years of Chemistry you learn in school, with maybe some university level concepts sprinkled in the mix.
This video is a good summary for preparing for exams and finals. Maybe. Perhaps.

Now go learn all of Chemistry. And share this with your friends who suck at Chemistry

Michio Kaku: The Universe in a Nutshell
Watch the newest video from Big Think: https://bigth.ink/NewVideo
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...

Take a mind-blowing voyage to the most powerful and mysterious objects in the universe. (Aired January 10, 2018)

Official Website: https://to.pbs.org/3P9TdDL | #novapbs

Black holes are the most enigmatic and exotic objects in the universe. They’re also the most powerful, with gravity so strong it can trap light. And they’re destructive, swallowing entire planets, even giant stars. Anything that falls into them vanishes…gone forever. Now, astrophysicists are realizing that black holes may be essential to how our universe evolved—their influence possibly leading to life on Earth and, ultimately, us. In this two-hour special, astrophysicist and author Janna Levin takes viewers on a journey to the frontiers of black hole science. Along the way, we meet leading astronomers and physicists on the verge of finding new answers to provocative questions about these shadowy monsters: Where do they come from? What’s inside? What happens if you fall into one? And what can they tell us about the nature of space, time, and gravity?

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.
