Stanford Professor Andrei Linde celebrates physics breakthrough
Assistant Professor Chao-Lin Kuo surprises Professor Andrei Linde with evidence that supports cosmic inflation theory. The discovery, made by Kuo and his colleagues at the BICEP2 experiment, represents the first images of gravitational waves, or ripples in space-time. These waves have been described as the "first tremors of the Big Bang."
Producer: Bjorn Carey
Video: Kurt Hickman

He taught a physics course I took at Stanford, and it was clear he was a genius. His exam questions reflected that too.... Much to my dismay.
What's most amazing and touching about his reaction is Andrei Linde's skepticism. Even when presented with concrete proof of his life's work he asks "What if I am tricked? What if I believe this just because it is beautiful?" This is the mark of a true scientist - the commitment not to his own beliefs, but to the reality behind them.

You sir, have your head screwed on tightly, i respect that :) I totally thought the same thing. I do not to start hate or anything, like everyone has their own beliefs and opinions, but just me, myself personally, couldn't have my faith and belief stored souly on blind faith, and believe something because thats what history has told, humans aren't the most trustworthy creatures, they like to exagurate and lie about things, which effectively leads to history being told differently, just like a big game of 'Chinese Whispers'. i like to have an open mind and think, "what is really out there? beyond just us and our planet, and solar system? what other life is there? surely we cannot be the only inhabited planet?" the universe is a strange, wonderful, mysterious and beautiful place, larger than any of our minds can even begin to comprehend. That is why it facinates me so much, I can't wait for even more groundbreaking discoveries in the future :D

@@homicidal_duck Thank you for telling me, I think I assumed because he seems to specifically want to tell Professor Andrei, but I shouldn't have jumped to the conclusion she didn't know what was being said.
When his wife said "Discovery", it was so much pure emotion in one word, gave me such great goosebumps. That's a one of a kind moment.
Their reaction is so touching. She is clearly brilliant and so warm and when it really hits him, the look on her face is so happy and genuine. And he is just so grateful and thrilled. Chao-Lin Kuo must be happy to be the one to deliver the news first.
In 2021 this is still one of my favorite videos on all of KZread
I have no idea what Kuo was telling him at the door, but the look on his face when he realized his life had changed was just adorable!!
Even as a lay person I understand that this is like telling a blindfolded cartographer circling over an area in a plane for forty years that the island he's been drawing does indeed exist beneath him. I can only imagine the joy of having such a massive theory proven through discovery. The same type of joy seen in Prof. Kallosh a 0:51. Congratulations to you, Professor Linde and the entire research team.
Confirmed or not, Andrei Linde is an adorable person.
i love how he remains skeptic even though he was being skeptic about something that helps prove his theory. that's a true scientist right there
This is absolutely astonishing! My Sincere Congratulations to Andrei Linde, Renata Kallosh & Chao-Lin Kuo ... the look on Renata Kallosh's face ... the momentary look of anguish and gratitude ... Andrei Linde's reaction ... after years of extraordinary toil and believing in something beautiful that may be a myth. An extraordinary moment to see this Redemption! ... Simply Beautiful ...

Uplifting and magical. How lucky we are to be able to say 'I was alive when people learned how to view the beginning of the universe and time expanding'. His wife's face at 0.50 says it all, so much emotion & joy in discovery & knowledge. It's a beautiful and wondrous thing, this universe we live in.
Most of us have probably already read the news of the discovery of evidence supporting the theory of cosmic inflation. This new found evidence goes a long ways towards validation of the big bang and gravitational waves. The thought that humans have this capacity to theorize and validate such monumental scientific knowledge overwhelms my emotional capacity at the moment. This particular video makes that discovery so personal. Just pay attention to the reaction from Prof. Linde's wife. Absolutely Priceless.

But even more, I love Linde, at 0:50, questioning, processing, finally comprehending, and then almost passing out on his front porch. Such a beautiful moment of validation. And, I must add, the smile and the "thank you" at 2:24 are among the most genuine things I've ever seen from a human.
To realize such personal fulfillment. I'm honored to witness it.
There's just something magical about this, to be told by your peers that you are right. All those years of hard work culminating in acceptance at last. Few moments like this are ever captured. Very well done.

How wonderful for the professor and his wife! You did a good thing, Professor Chao-Lin. Thank you for letting us watch.
Actually, it turned out that the BICEPT 2 data was caused by interstellar dust noise and the discovery was acknowledged as invalid. You should put some updates on that.
Love the associate professor's delivery: "r equals .2, plus or minus .05". I'm teaching writing for the sciences this term, and this is the perfect illustration for precision of language being the most powerful thing we have. "Awesome" or "incredible" or "mind-blowing" don't come close to it. Loved her reaction -- first hug the messenger, then hold up the man when he starts to sag.

"This is a moment of understanding of nature of such a magnitude that it just overwhelms."-Well said, Andrei Linde. This is the cosmos evolving and becoming aware of itself and gradually understanding its own origins through its children, humans. One of the moments in science which give me goose bumps.
5σ means 5 standard deviations, repeating experiments would give the same result 99.9999% of the time. r is a more complicated term, which is better explained by a comment below. 5σ is the acceptable probability value in physics. Congratulation to them! Also thanks to mogget03 for correcting what r is.

Have you ever wondered what it feels like to have an entire lifetime of hard work, meticulous testing and experimentation be confirmed in a single moment? I got a glimpse of that watching this video. Bravo to everyone involved with this discovery!
It must be an indescribable feeling when one's life's work in science is finally validated.
As a former Physics student back in College, this brought tears to my eyes. I remember when I was about, oh, 8 or so and this stuff started being talked about on the Science shows I used to watch as a kid etc. Must have been an incredible moment for both of them. Congratulations!

On the other hand, Linde, whose name is now etched in stone, is now virtually unknown to the masses.
His reaction is so wonderful. The disbelief turned to happiness. After he asked for the 3rd repeat, I was smiling from ear to ear. What a victory for science, to see Professor Linde get the recognition he so clearly deserves, and has had coming to him for 30 years. Congratulations Professor!

Not the Asian horned beetle, but the African. He is living his life in utter peace and harmony, soaking up valuable grant money so desperately needed by real problems. And when one grant runs dry. he cons another university onto funding more of his "research". And there are thousands more like him out there, just kicking back, skating through life without a real purpose. If you're country is losing these purveyors of snake oil, then you are fortunate.

To think that today we live in the craziest most unimaginable place ever, where the particles that form the person you are and everything you see around you were created in the center of stars. Thoughts and ideas that spark out of nothingness, which then manifest into the technology we see in our every day world. I don't see anything better to spend the money on.

A beautiful moment for Linde, for humanity and for science. This man questioned his own work for 30 years, even though the conclusions he came to back then were beautiful and likely incredibly fulfilling. Still, he insisted on evidence because he knew his own mind was susceptible to "being tricked," as he put it. It was a very pure and human moment to see the look on his face when he finally got his validation. We should all hold our own theories and beliefs to such a standard.
