Very well said. And true of both Fermi, originally, and Dyson as he saw the truth in what Fermi had said.

What an unflinchingly honest self-assessment. Earlier in the series he tells us of the very high goals he set for himself as a young mathematician, and where he admits his failure to solve an extraordinarily difficult problem in Diophantine approximation (solved only years later by Klaus Roth, who won a Fields Medal for his efforts). It was then that he decided to start his career in physics. And now he tells us that he wasn't cut out to be particle physicist, that he was really more of a mathematician after all. He was a towering figure in both of course, and his modesty is very moving. In fact this is one of the most moving scientific testimonials I've ever seen.

Imagine a world in which every person could admit their limits, recognize their faults, and just accept the reality of being wrong about something with this same grace. That's my idea of heaven.

He is, however, not one of the kooks that denies what is going on, in fact he very much agrees with most's view of what is happening with the climate and its causes. He just doesn't agree with the political side of things as he believes we have much bigger problems that we should be investing our resources on. After reading some of his thoughts I cannot say that he is nuts or anything like that as there is some very good thinking behind his words. I urge everyone to do a bit of reading before using KC's comment to judge the man. Also, one note on his lack of expertise in the field. Dyson directly answered that challenge with ""my objections to the global warming propaganda are not so much over the technical facts, about which I do not know much, but it's rather against the way those people behave and the kind of intolerance to criticism that a lot of them have.". Unlike the way in which you tried to present this part of his life when, you look at his work there are few that have stretched their minds in so many ways as to man's future and our species continued evolution alongside technology. You have to a bit careful when you say that something is outside of the purview of the fields of theoretical physics and mathematics as, well, is there anything that those two areas of thinking do not include? Everything is physics and it is all explained by maths so I have no problem in listening to, and respecting, this man's opinions concerning most anything, no matter if I agree with him or not.

One night, while I was part of a retreat of the high-level administrators of a college, a retreat that was held at The Seven Pine Resort, I realized that this was THE Seven Pines, home of many retreats of the world's great minds in physics and mathematics (and a few philosophers), I went through this very nice but humble, unpresuming facility because I had a background in physics and astronomy. I knew about the Seven Pines Retreats, the long list of many of the world's great minds in physics to discuss the unsolved, intriguing problems in the field. In an old room, with glassed-in cabinets for books, many books, the library, I began looking through the titles, and pulls out one intriguing one that I didn't know, to see what was in it. The opening blank page had a note, nicely hand-written to the wealthy person who owned the Seven Pines Resort, whose interest in physical sciences inspired him to use his wealth to gather groups of the world's great physicists together once a year on some particular topic. The note thanked the owner of The Seven Pines for his wonderful idea to do this, for having invited him to share in that year's retreat, and offered this book as a thank you. The note was signed, "with my great respect, Freeman Dyson." When I read that name, and suddenly knew that I was holding the book that Dyson had signed, I momentarily reeled a bit, the mind whorled, and then a short elation came over me that I was ever, even once in my life, this close to Freeman Dyson. I didn't want to own the book. Just holding it once was the best experience I might have of ti.

Remember Fermi invented the atomic bomb mathematically and proved it would work. Oppenheimer was only a "plumber" assembling the parts Fermi gave him the designs to. Fermi insisted there was absolutely no need to test the "gun-type uranium bomb" (Little Boy) and he was correct. It tested Hiroshima to the ground. The "implosion plutonium bomb" (Trinity and Fat Man ) needed mechanical testing . In a little more than 9 months, Fermi took the theoretical concept of an atomic bomb into design plans, and had to wait on the fissile material to be isolated and purified.

Before the Manhattan Project even came into existence, it was the joint work of Fermi and Szilard to demonstrate the theoretical feasibility of a chain reaction. And it was Fermi's intuition to use graphite as neutron moderator and the necessity to manufacture it as free of impurities as possible that opened the path to the construction of the first nuclear reactor in Chicago, beating the German team by several years, as Heisenberg insisted on using heavy water as neutron moderator. The chain reaction is the physical mechanism that frees up the nuclear energy, so creating that is the fundamental contribution that opened the way to the whole field of applications of nuclear energy

Then you get into "What are the unknowns" and "Are there limits to what can be known?" "What are the rules for limits?" and of course, the boundaries of applicability.

Great Freeman Dyson. On the other end... It is very useful to have a genius available nearby, one that is always right. Fermi was key to the speedy development of the basis of nuclear technology. From what I recall, Enrico Fermi missed a beat only once, when he designed the Hanford reactor to produce plutonium. After six hours the reactor reached criticality, the level of activity suddenly and unexpectedly decreased. It took Fermi few minutes to deduce the cause, the formation of xenon - which is a reactor poison; and some more little time to find a solution: 500 more rods. Thankfully the military always think about contingency, so they added extra slots to the design. Another person from that time which had a similar genius mind, able to make the correct deductions with little or no data - was Lise Meitner. Previously, she was able to deduce correctly all the products of the fission of uranium in the blink of an eye; something that Otto Hahn (who got the Nobel) was unable to achieve. Mrs Meitner was Jewish and has to flee her country, but kept working from afar and produced such genial answers to the nuclear conundrum. Thanks for the video...

It’s amazing to be alive during this time period. People far in the future will look at Dyson and others as himself as the foundation of science.

Thank you for this wonderful series. I find it helpful to see, in such an intimate discussion, that even for a giant like Freeman Dyson, whose mathematical skills I could never remotely approach, there are limits of talent and intuition which one has to admit and deal with.

If Fermi was alive he would have probably shit on the theory of quarks too.

He was always considered a physicist, but he wasn't. He was probably one of the best ever applied mathematicians who ever lived

I needed this!

What humility Dyson shows after years of working on mathematics of the highest order- when Fermi could pinpoint the theoretical flaws in an instant.

Humble man

If ever a man were able to define the ideal of "scientist", in the realisation of the idea of a person who can accept evidence as what it is rather than what he wishes it to be, and use it to improve the human condition, it would be difficult to find a better candidate. Equal perhaps, but rarely better. Thank you for posting this.

What a wonderful lesson!

Wonderful interview, thank you.

It takes a honesty and a strong character to be corrected like that by ( possibly) one of your heroes and take it positively and use it as a wake up call and better yourself. Yes it hurts and it is tough to hear: I’m not impressed by your work, but that is not the end of you and it invites you to change for the better. And mr Dyson clearly did.

Such a great story

Wonderful man.

Humble guy, I like him.

Failing is learning.

very interesting

What a great man

Did not understand a great deal of what Professor Dyson put forth, and it was still better than man's religions.

How many dimensions are there in String "theory"? Eleven? I bet you can make an elephant do the tango with eleven parameters!

Dimensions are not free parameters. Also string theory very much fulfills Fermi's second criterion of having a rigorous mathematical basis.

What an unusual and gifted man.

His vacuums are great.

Science is a very human form of knowledge. We are always at the brink of the known; we always feel forward for what is to be hoped. Every judgment in science stands on the edge of error, and is personal. Science is a tribute to what we can know although we are fallible. Jacob Bronowski

Wonderful quote!

An example of how it takes genius to recognize greater genius.

Yes, humans are involved. Ego's and mistakes abound.

Dyson... the man! Orion project, was the last hope for humanity

The rare ability to stand aside from oneself and look at what is going on, then set one’s ego involvement on the shelf and move forward.

What a MAN!

I wish people were as aware as he was that physics and mathematics are quite different things, regardless of how much they share in common. Mathematics may be a tool for physics, but not necessarily.

Bless you Freeman: inventor of the vacuum cleaner.
