- Everyone knows quantum mechanics is crazy and mysterious. What they don't know is that the history of it's discovery is just as odd as the theory. Physicists spent decades chasing strange clues about the atomic world before finally deciding they had to completely alter the way think about the universe. This unfamiliar road often led to self-doubt, and turmoil and disputes among some of the worlds most brilliant thinkers. This journey into the unfamiliar ultimately echoes the path we all take as we navigate the many opportunities and decisions that make up the story of our own lives.
Leonard Mlodinow is an award winning author and physicist holding a PhD in theoretical physics from UC/Berkeley. Mlodinow is the author of 9 books, five of them bestsellers: The Drunkard's Walk: How Randomness Rules out Lives, Subliminal: How our Unconscious Mind Rules our Behavior, The Grand Design and A Briefer History of Time both co-authored by Stephan Hawking, and War of the Worldviews written with Deepak Chopra. He also wrote for numerous television series, including Star Trek: The Next Generation and MacGyver.

The most important "lesson" from this talk is the realization that scientists are human, which means they often carry the same kinds of closed-mindedness and derision towards things they don't understand - like new, cutting edge theories - that ordinary folks do.
We have this myth that scientists are these purely rational, logical, dispassionate observers of reality who are not influenced by the sames sorts of "prejudices" that everybody else is. But nothing could be further from the truth. And this same negative trait in his fellow scientists even caused Max Planck to lament: "Science advances one funeral at a time."
Sometimes the old curmudgeons simply have to die off before the "atmosphere" will allow significant advancement.
A good reminder. Science is perfect scientists are not.
Funny how none mentions de Broglie as both Heisenberg's and Schrödinger's approach was built on de Broglie's idea. Moreover, Schrödinger developed his equation to generalise de Broglie's theory.
EXACTLY! I'm watching and he jumps to Schroedinger from Bohr? Hold on! It was de Broglie who combined quantum with relativity - and his Law of Phase Harmony has yet to be appreciated fully.
Clearly, it is time for Boros Gábor and Voidisyinyang Voidisyinyang to create a TED talk to address this serious oversight!
Mlodinow is just incredible. I have only begun studying his commonsense explanations of human interaction, and now this. I have so much more to follow up with. One more audiobook (if available) or printed book to buy and study. I am totally amazed that I have missed out on so much that is available today.
Amazing talk. It is really interesting to learn how the theories and the facts that we take for granted now, took so many years to be proved.
Theory of light and matter.
The saga of unending .
"Why abandon a belief merely because it ceases to be true Cling to it long enough, and it will turn true again, for so it goes. Most of the change we think we see in life is due to truths being in and out of favor."This quote from Robert Frost remains true today and continue remaining true as long as nature exist because nature is not absolutist

I felt QUANTUM MECHANICS is fun !!!!!!!!!!!!!!!!!!
All this talk on light yet gravity is fundamentally just as if not more important to try to understand
Planck's theory was not about atoms. Einstein's 1905 work was not about Planck's. If you look at the original works you will see that.
Why can’t scientists communicate.
How about learning to spell? "history of it's discovery" should be "history of its discovery", without the apostrophe. "Its" is the possessive form of "it" (ie "belongs to it"), and "it's" is a contraction of "it is" (eg "its hot") or "is has" when "has" is the auxiliary verb (eg "it's been fun")
This dude should first learn to speak .
