Only a fool can be deceived into thinking that random proteins can magically self assemble into complex DNA and RNA. Especially since there has never been a repeatable experiment done that demonstrates the hypothesis of random self assembly of organisms. If you are so clever and I am so foolish, then please recreate the genesis of complex life in a lab. If this theory were true, everyone on the planet should be able to combine the ingredients needed for life and then magically get these ingredients to become a complex life form. You can't do it, nor can anyone on this planet. It has never happened and will never happen, because it's an incorrect hypothesis. The data does not support the notion that life just happened to happen. Or, put into simple terms that a child can understand - 747s do not build themselves even when all of the pieces are present. Apparently, that analogy is over your head or beyond your cognitive capabilities since you felt the need to attack it. Maybe you can get a distinguished biologist to prove that random chemicals and proteins can be brought to life in a lab. If that ever happens, I will rescind my opinion and apologize for my error. I doubt that you will ever prove that but anything is possible.

In words of wisdom, Paul Nurse did share, The core principles of life, a truth so rare, Nobel Prize-winner, in science's brilliant glare, He unveiled life's secrets, beyond compare. Principle one, the heart of all existence, Information's flow, a grand persistence, Genetic code, in cells it finds its stance, Life's blueprint, in every single instance. Principle two, diversity's graceful dance, Variation's key, in each life's advance, Evolution's art, through time's expanse, Survival's essence, in nature's romance. Principle three, the mighty energy's exchange, In every cell, a balance we arrange, Metabolism's dance, so intricate and strange, Life's spark, in every molecule's change. Principle four, the cells, life's building blocks, Complexity emerges from simple locks, From molecules to tissues, in paradox, Life's beauty in cells, where harmony docks. Principle five, the generations' thread, Reproduction's gift, where life is spread, Inheritance's tale, from ancestors led, Life's tapestry, in the DNA's spread. Paul Nurse, in science's quest profound, Unveiled these principles, on fertile ground, In Nobel's glory, his knowledge unbound, Life's mysteries, in his wisdom found. So let us heed these principles five, In nature's grandeur, let us derive, The essence of life, where mysteries thrive, In Paul Nurse's wisdom, let us survive.

Great lecture ! Thank you very much, Mr. Nurse. I wish you all the best for the future and I am keen to listen to your next lecture! Greetings from Switzerland.

I'm beginning to think that the reason it is so hard to answer this question, what is life, is because it isn't actually a thing in itself. We see a part of the universe moving around and doing stuff and we call it life, but this is a concept or even a category that we have in our heads. You can say the same about tornadoes or hurricanes. They are self-assembled structures that form due to an energy imbalance, but they are not really a thing. That is why nothing is lost when a whirlwind finally dissipates, because it was never really more than an identity put on it by some human mind. If life is like this, and it seems to be, then the most you can ever do is describe it and work out its dynamics, but you will never really be able to say what it is.

Then, at the end, you stated that humans are the only life which sees the connectivity of life. Symbiotic life also "sees" the connection. Otherwise it wouldn't know which life it needs a symbiotic relationship with.

I agree. At about 10 minutes in, he said something about the 2nd law of thermodynamics not being a problem because the cell is separated from the environment. This seems arse-about-face to me: the 2nd LoT isn't a problem precisely because the cell *isn't* a closed system and is constantly exchanging materials and energy with the rest of the environment. I suspect he's one of the "old school" of great biologists who weren't so hot on physics (I know: I could google him). Especially given his Schrödinger/Heisenberg Uncertainty Principle whoopsie. Still that's not really why I'm watching, and it's been interesting so far.

Charles Darwin being famous for the theory of evolution after his grandfather was essentially run out of business for having that idea is kind of an amazing story I mean I do wish that his grandfather would have gotten the credit whenever it was his idea but still inspiring in its own unique way

There's a book.coming out this week which contends that Darwin was a fraud and plaigirized everything from contemporary Patrick Matthew. Gonna check it out, sounds pretty interesting.

Heisenberg formulated the uncertainty principle, Schrodinger gave us wave mechanics with an equation for atomic wavefunctions

Interesting, love it.

2:42 "Schroedinger, he of the Uncertainty Principle". The Uncertainty Principle was formulated by Werner Heisenberg. Erwin Schroedinger formulated the equation . the wave function of a quantum system.

These parameters fit well into the earth’s environmental changes. But on another planet, for sample, with no environmental changes there may be no need for evolution or reproduction, etc. This video should not and cannot be the only basis for our search for extraterrestrial intelligence. But this video does make one wonder how fantastic are the differences of life in our universe. And just how soon will we have the ability to connect with the universe’s other self aware entities? I only wish it could happen in my lifetime. Thank you, Paul.

Life, consciousness, intelligence, intuition, faith etc., are metaphysical dimensions evolving out of matter (physics). These extra dimensions are what string theorists indicate.

2:36 Werner Heisenberg formulated the uncertaintly principle, not Schrödinger(whose equation the principle was based upon because of the probabilistic interpretation of it).

Brilliant lecture, thanks. It seems that we often look for a definition of life using micro systems from ourselves down but in reality we reach a difficulty with that approach and end up going macro on our examples. Maybe a forest is alive, maybe humans are part of larger wholes or ecosystems and who knows how far it goes up?

Around and around for infinity ?? Every species dies, but maybe other things are created...

This is a very well done lecture, and really worth an our of time, but something is missing--the proverbial Elephant in the room. Nurse describes the organization and processes of the cell quite nicely (and in some depth), but he doesn't give any explanation as to what starts the processes, and what drives them. In other words, what is the make up and character of the force behind the most fundamental aspect of biology? What is that life force?

A brave man.

Excellent. He could have mentioned seeds, which look totally dead until placed in a nourishing environment. They are similar to viruses in this regard.

The uncertainty principle is from Heisenberg, not from Schrödinger, professor.

Two comments, I believe it was Heisenberg and not Schrodinger who developed the uncertainty principle. Second, certainly purpose evolves as a result of evolution, but I think it is a more significant element than that. It is purpose that drives evolution. It is purpose that provides a measure of success for a new birth to succeed and therefore reproduce. This concept of being able to measure the relative value of one option vs. another is the key to be able to create order from disorder. It applies in areas other than life.

Superb.

I spent much too much of a long life trying to get some computer to do something useful. One thing that plagued me was that any error, no matter how slight, made my code fail. If, as Dr. Nurse says, life is based on coded information, where did it come from? We all know that DNA code is immensely complex and sophisticated. Yet it is present in all life we have ever found, no matter how old or how primitive. So, where did it come from? A side note. I am really interested in knowing why Dr. Nurse is so keenly intent on eliminating the possibility that there was an intelligent creator. What is the psychological need here?

Who created the intelligent creator? Is he alive? Is he DNA based?

David, life has a terrible and unforgiving logic to it that explains your question quite well. Anything that makes an error, no matter how slight, dies. Evolution is all about death. The reason all the wild animals almost always look perfect and error free is because the defective or weak die, either before birth or shortly after, sometimes by mom's appetite. If you see your creator around the coffee shop, you might inquire about his penchant for killing the weak in gruesome fashion.

"WHAT IS LIFE?? BABY, DON'T HURT ME. DON'T HURT ME, NO MORE."

What is life? That brief period of time between our eternity of nonexistence.

@Bob Trenwith Exactly. The "life" of a soap bubble. You are limiting your definition to *your experience* as a human being, alone in the universe, living on a spinning rock held up by _nothing._

Thank you
