    I just loved this interview. I also failed French (once) which I required to enter a British university. The funny thing is that for the last 48 years I have lived in a French-speaking country. My French teacher would have had a heart attack if he knew.
    Evidently I do now speak fluent French, but in fact I learnt to speak on mountaineering expeditions with the Club Alpin Suisse (whose members were very polite about my terrible accent).
    Whether passing French should be a requirement for university entrance one could debate, but I now understand that speaking a second language does give me a different perspective on the world, so it is certainly worthwhile. I also see that my bilingual daughter and grandchildren have an enormous advantage as compared to monolingual English speakers.

  • @SandipChitale
    @SandipChitale 3 ปีที่แล้ว +2

    We have to remember that to the extent we know, all over the universe there are 110+-10 elements occurring naturally, on the menu. Of which carbon seems to have the 4 covalent bond based stable enough and very rich chemistry in collaboration with hydrogen, oxygen, nitrogen and few metals. Silicon has 4 covalent bonds but the associated chemistry is not rich enough as it appears in nature. Therefore the life (based on physics -> chemistry -> biology -> information processing) anywhere in the universe - if it occurred naturally - is likely going to be carbon based. For the occurrence of complex life stability aspect of carbon chemistry is an important aspect - because complex life takes billions of years to evolve. The richness of carbon chemistry aspect is conducive to diversity of the living organisms built on diverse set of physical structures. For that reason any naturally evolved life elsewhere may not be based on anything other that carbon chemistry - in terms of higher likelihood.
    It is popular in many science fiction stories to imagine silicon based life forms. But IMO they will be NOT be naturally occurring and they don't have to be - because the carbon chemistry is an easier and more conducive path to life. Silicon based life will be second order or derived from natural life. Let me explain....
    As discussed in the video the life is ultimately information processing. So once complex lifeforms like humans that evolved out of carbon chemistry, understand that the essence of life is information processing - with the ability of technology to build things - then such complex lifeforms could use silicon to build information processing lifeforms - but not using chemistry but the language of information processing and computation science i.e. physics of transistors built from silicon vafers, and AND, OR, NOT logic gates built from it and connected in vast networks which thus bypass chemistry and biology and directly instantiate information processing life forms. Of course these life forms will need hardware bodies to interact with the rest of the physical world i.e. Robotics.

Each sentence is full of brain stimulating ideas especially if you are into the several scientific revolutions and interconnectivity that we are all living between all sciences and interaction of social sciences with the natural sciences never to be separate again. Neuroscience, biotechnology and synthetic biology have placed law, ethics and social implications as a new view of our world.

    These guys are both brilliant scientists. Greene is a phenomenal genius being able to popularize some really deep and complex knowledge while standing firmly his scientific grounds. Yet, everybody gangsta till the hard problem of consciousness arises. All kinds of scientific physical explanations hit a wall when they confront the question of the nature of consciousness and how it is related to matter. There is absolutely no explanation how matter and the laws of physics and chemistry can create consciousness or explain what consciousness really is in nature. So, we might have to consider the possibility that consciousness is the fundamental element that precedes all life and matter as we know it from which everything manifests including matter and natural laws, as more or less Professor Donald Hoffman, very much a scientist, suggests with his Case Against Reality. Fascinating stuff.

    Homeostasis is that the body maintain some kind of balance in the body, like keeping the temperature at 37,5 degree C, keep the concentration of blood-sugar at a certain level and so on. This is local order and to get it we use of the total order so that it decreases according to the entropy-law. As long as we keep the balance, we feel ok and are comfortable, if it comes out of balance, we will often feel it and know what to do about it. In this way feelings are important to us.
    So are social and mental feelings also and it is important for us to understand how and why and to find the good balance. The point is not to regard all that tends to make imbalance as bad, but to understand what to do. For example in Piaget’s (biologist) pedagogic theory the pupils faces problems that bring them into slightly mental imbalance that motivates them for learning.
    Some get difficulty with this, maybe they can get help from a priest, a psychologist and/or a psychiatrist. Then they may get the diagnosis as “the patient”, taking it for granted that there is something wrong with him and/or her. For they just have to adopt to the environment, if they don’t, it is their fault, that’s how the survival of the fittest is. But if they didn’t fit into a special society, it is not certainly their fault, there may be something wrong with the society, that the social life does not function quite well. What to do about that? This they need to find out of, to see how they can fit into the society in a better way, maybe another part of it.
    The patient may come into an emotional imbalance that is hard to explain except that this is the diagnose and this is how the patient is. The psychiatrist is a doctor of feelings and gives the patients drugs to bring them back to emotional balance. In this way the real social problem may be obscured and not solved and the need of drugs become artificial, the problem is not solved like naturally adopt to the environment (society). Isn’t this also the explanation and the problem with the illegal drug trade? The drugs gives them an intoxication that makes them feel well and comfortable, normally that should tell them that they are doing well and survive, but they cheat themselves, it may even make them feel better than normally, even though it is poison that actually bring them closer to death. So it make them enjoy their own self-destruction.

    Humans aren't the limits of either life in scale, or intelligence. It's possible to imagine a being/beings that convert the entire universe into a highly ordered state. Even more perplexing if they manage to disable entropy as a fundamental concept of the physical universe. You could then say the destiny of the universe wasn't actually total chaos, but total order.

    On the subject of immortality, I’d suggest as a segue to this remarkable conversation, an interview with Dr. Michael Levin. He has been conducting groundbreaking research on bioelectricity and its application to tissue regeneration. His lab at Tufts University decoded the bioelectric signals that the planarian flatworm uses to grow a new head or tail, regardless of how many times it has been cut off. Levin believes that bioelectricity is the path to tissue regeneration in humans as well.

    With regard to free will, individuals have differing bandwidths of the expression of free will that Paul alluded to in terms of societal limitations. This comes under the purview of the Vedic concept of individual karma. I have some speculatory ideas of how that may work biologically within the framework of genetics and epigenetics. This is a wonderful conversation, I wish I could work on some of these concepts with Sir Paul.

    In the embryonic stage (early fetal stage) there is an abundance of nerve cells and synapses, so it seems like a competition between them to survive, those who are most in use survive, others die. Later in life, the nervous system is remodulated in response to its own activity. It is called neuron plasticity. The neurons make contact through the synapses, if there is a lot of activity through the synapse, the presynaptic neuron will make additional axon terminals (like making more lanes leading into a highway) and/or more receptors/channels for neurotransmitters (glutamate) in the synapse. If there is little activity, on the contrary it is reduced and the contact can be broken. This is considered to be the physiological basis of memory.
    "Afferent neuron" gives signals to the brain. "Efferent neuron" sends signals from the brain, through the motor system to control skeletal muscles (so we control it on purpose) and through the autonomous system, it works automatically. The autonomous system is divided into three parts. 1. The enteric division the signal goes to the hormone glands. 2. The parasympathetic nervous system goes directly from the brain stem and out into the body, it gives orders of the character "fight or flight". 3. The sympathetic division goes through the spinal cord and out into the body and the order has the character "rest and digest". In 2&3 pregangliolic neurons lead to synaptic stations called ganglia, post-gangliolic neuron carry the order further to the muscles, smooth muscles, since it is automatic. The neurotransmitter is acetylcholine except for post-cangliolic neurons in the sympathetic division, where it is norepinephrine (norepinephrine). This is what causes the effect on the muscles to be the opposite.
    Then we can say that information is coded by neurons and hormones. But there are only a few kinds of them. The point is the effect from the body when they are sent and the body when they are received.

    I can't find a book by Ian McEwan named _I Robot_ . Are you getting the title confused? The novel _Machines Like Me_ seems to have a suitable plot and the robot's name is Adam, so that might help you get your wires crossed (Adam Link is the robot in the original _I Robot_ ) and you earlier mentioned "Asimov's [sic] I Robot", a movie which has nothing to do with Asimov's Robot stories other than to appropriate a couple of character names (characters that are completely unlike their namesakes).
    The reviews of _Machines Like Me_ are mixed and so polarized that I'm wondering if it's worth reading.

    Brian, Paul makes me think that perhaps you should do something on language learning. i know that this is not in your normal field, but Paul's experience is so common. Definitely the way languages are taught in American universities are useless for all but the few that have a particular talent for learning languages.I am bilingual, but it took total immersion. I had to only associate with people who did not normally speak English, my native language.

    Blown away by the way Sir Paul Nurse answered the semi-provoking question about the nationalism. It was so easy to go along with the whole “Down with Nationalism!” agenda.
    But he made a clear observation that the nationalism is not the problem, the sheer ability to explain the isssue is much more important.
    Bravo!

    We benefit from being social, but in this corona-time people are more lonely and for many it is not so good. For some people it results in poor finances and financial depression can also contribute to mental depression. There is certainly a lot we can do to avoid becoming depressed, for example exercising, going for walks and keep ourselves in good physical shape.
    There is a lot of memory in the body, even though we are not conscious of it. In the immune system, it can host memory cells that make us resistant to disease. If we are well trained, the muscle cells remember it, so it will be easier to become well trained again. They have found out a lot of what function different areas of the brain have, we have different kinds of memory in different parts of the brain. But it is still a mystery what consciousness is and how memory is coded.
    What we choose to be concerned about and choice of friends is important. It affects the state of mind. We know that hormones are important for the state of mind and this is how many drugs work, but my point is that the state of mind also affects the hormones. And to a certain extent you can choose your state of mind.
    If someone believes in something, is trained in it, hopes for it and invests in it and then it fails, then it is obvious that they become sad and it can turn into long-term depression. On a Good Friday, it may be appropriate to recall that when Jesus and his disciples were in Gethsemane, they were all sad. Jesus knew he was going to be executed. But God raised him up from the dead and that changes everything. The cross of Jesus tells of a death, but is still a life-giving and joyful message, because he rose from the dead. It gives us hope of eternal life and the glory of God and that hope does not disappoint us, because he gives us the water of life for free, by mere grace, without the requirement of any work. The love of God is poured out in our hearts by the Holy Spirit who is given to us (Rom.5,5).

    Prof Greene, If space time is quantized into discrete units in the size of Planck length in each dimension . can we assume that between these units there is a 3D grid like extra dimension (or dimensions?). can these non local grid dimensions explain the non local behavior of quantum mechanics (like quantum entanglement or quantum tunneling) ? I can visualize it much easier than the local Calabi Yau curled extra dimensions that can not add any explanation to the non local feature of quantum mechanics.

    The increased importance of engaging the public in decisions about the impact of science and technology on society has been recognized for quite some time by academics. The National Academies of the US has recommended that policy should be “a democratic action aiming at an optimal tradeoff between a number of different agendas and viewpoints; scientists cannot rule that discussion. The problem is on the policy-making side; we need to figure out how to better integrate science into the political process (6).” In the case of new genetic editing techniques, the National Academy of the USA recommends the implementation of safety and ethical regulations as the best strategy to avoid the loss of public trust, and thus preserve the potential of the technology to benefit humanity (6).
    The engagement of an informed public could enhance ex-ante precautionary policy design with added clarity. Recursive public discussions are one of the mechanisms to bring foresight and robustness to the policy decision-making process. The outline proposed by the Royal Society under the concept of “intelligent openness” (7) provides a road map for the changes needed to make Science and Technology more open. As summarized by a newspaper piece calling for public informed involvement (7): Intelligent openness requires that the data used to make scientific claims are accessible, understandable, usable and assessable. “Accessible” implies publication online at minimal cost. “Understandable” means claims made in plain language, as clearly as possible. “Usable” may mean supplying data in a format easily analyzed by computers, and it also suggests that the conclusions be framed in a way that is relevant to everyday concerns. “Assessable” means that anyone with the time and expertise has the detail required to rigorously test the idea if they wish. That is something scientists, statisticians, economists and other “experts” can do. What the rest of us owe them - and more importantly, owe ourselves - is to ask a few questions before we spread an idea on social media or rely on it to govern our votes, our diets, or our attitudes to each other (8).
