What is life?

  • Publicado el 27 nov 2011
  • In spring 1943, Nobel Prize winning physicist Erwin Schrödinger gave a series of lectures at Trinity College, Dublin. These lectures were subsequently published as the non-fiction science book 'What is life?'.
    Schrödinger took a physicist's approach to the question, asking whether living organisms could be understood in terms of fundamental matter. Francis Crick, co-discoverer of the structure of the DNA molecule, has credited the book as being the inspiration for his initial research.
    In this lecture, Nobel Prize winner and President of the Royal Society, Sir Paul Nurse, also takes inspiration from the book to ask what can we now say about the nature of life?

    I literally think about this every day. I can't get the idea out of my head that we (humans), and everything from viruses to blue whales, and all our precursors and ancestors, are incredible chemical machines, replicating ourselves while concurrently adapting each generation to better suit the environment. we don't even know how beautiful and rare we are in this universe. Life is the universe observing and experiencing itself. humans provide subjectivity

    There are good reasons to believe carbon based life to be the most probable. We obviously are not at a point to dismiss other possibilities, but I wouldn't call his stance as "arrogant" as he is even recognising that there could be other possibilities. Also it is not, if you aren't talking about something else, carbon that can be replaced with arsenic but phosphorus. I see your point though.

    Excellent talk, but I do wish more of the slides were shown. What is he talking about at 55:00? Jacobo Mono and Lak Oberon? He mentions a slide he showed us previously, but I can't figure out which one that is. Could the slides be made available online? It would be very helpful.

    Nurse gave a similar talk entitled "The great ideas of Biology" which had slides visible on youtube. He probably used the same slides.
    As for the Lac Operon. It's very famous in molecular biology so he probably didn't think he needed to say much about it and skipped it. The genes for digesting lactose is only turned on when lactose is present, to stop resources being wasted. A protein binds DNA at the gene, stopping it being transcribed; when lactose binds that protein, it releases it from DNA

    the 'microscopic creature' didn't create humanistic life it evolved from a 'microscopic creature' millions of years ago into what we are now and its still evolving.

    I always think that while we think that humans are smart and know a lot of stuff, there are still many things to be known. and are these things understandable by humans so that we can find them out? and why do humans think the way how we think? lol. I don't know if my questions are weird questions.

    Intrinsically subjective point of view of Life. How limited is science when explaining anything. Who introduced objectivity? Think about it.

    Around 14:30 he begins discussing life elsewhere in the universe and assuming that if life here on Earth was based upon carbon that life must have evolved the same way elsewhere. Even on Earth there are living microscopic beings with their DNA lattice based on arsenic not carbon. I am not trying to be a pain but I feel this is a bit arrogant of humans to think this is the only way life can exist.

    oh woah, one of the most important things you could understand as a human being and only 16,000 views, while juster bieber gets i dont know how many million views for saying things like"baby baby baby"
    Dammit humanity, up your game already.

    But, What is life?
    You can explain life with all these biological theories etc. and you can also attempt to explain it with religion but non of this has any real proof. Yes the scientific approach has much more proof than the books written about religion but when you really think about it what proof is there really, especially when you think about my theory.
    Life is in the mind. Simple, this suggests that I am the only person alive and that everyone else is simply a figment of my imagination.

    Life is a miracle. God is love & life is the manifestation of love

    It is amazing to me that the so-called scientific community would prefer to believe that human beings were created by a microscopic creature (germ) rather than by superior being (god?). Is it because we feel that if we acknowledge the existance of a superior being we are then obligated to worship this being? Anyway, how is it possible for a microscopic creature to create a being that is outside of its microscopic realm. It would have no clue of the realm in which we exist. But a god would.
