S. Feynman, ‘Surely You’re Joking, Mr. Feynman,’ Kindle ed, 2018.

V. Ramakrishman, Why We Die; The New Science of Aging and the Quest for Immortality, Kindle ed., 2024.

Both of the above-listed books have this in common that they were written by natural scientists and are aimed at non-specialists. They also have this in common that their authors were awarded a Nobel Prize: Feynman in physics (2008), Venki Ramakrishnan in chemistry (2009). Not having taken more than a cursory look at either discipline since I graduated from high school—not college, but high school—exactly sixty years ago, I cannot say I understood everything I read. Not the quantum physics which, I am told, is something very few people have really mastered. And not the unfathomably intricate chemistry of life. Far from it, in fact.

What I did, or thought I did, understand was what the two highly respected professors have to say about the kind of atmosphere they did their best to create around themselves as well as the way they approached their respective disciplines and made the discoveries they did. “Way,” in fact, may be too strong a term. Neither book contains a systematic exploration of the scientific method and how to use it to make new discoveries; let alone has a separate chapter on those topics. Nevertheless, the more I read the more I felt there is a lot that, reaching across our very different fields, they and I have in common. So here are a few of the things that, joining the books and taking some leaves out of both, seem to me essential for any kind of career involving discovery, however humble.

– Mixing with people coming from different backgrounds, disciplines, directions, and approaches. To be sure, solitude may have its uses at times. However, no man is or should try to be an island unto himself for very long. Much the same applies to societies. As Feynman in particular explains in some detail, it is the mixing, not the formal talks and Q&A, that is the most important part of many of the scientific/academic conferences taking place all over the world today. Much of the time, all the talks do is provide a framework that endows the entire thing with a timetable that holds it in place. Without them, all the participants would get is chatter—kaffeeklatsch, as the Germans call it.

– As you go along in your work, leave some room for the unforeseen and the accidental. One of the scientists mentioned by Ramakrishman is a Russian molecular biologist by the name of Alexey Olovnikov. Going back to the 1970s, he got his most important idea concerning the way DNA duplicated itself while standing on a platform of a station in Moscow and watching a train go by. Likewise the best ideas often occur as a result, not of focused, systematic study—trying to drill holes in a cushion—but of sudden flashes of insight: the kind some people compare to a stroke of lightning and others call the “aha” moment. Yet this moment itself would not be possible without the problem at hand having been given deep, if often nebulous and even confused, reflection.   

– Don’t hesitate to challenge established views, including those of your superiors. Telling truth to power demands tact and is seldom easy. Still, very often for any kind of progress to be made it must be done. Politely, of course, and, whenever possible, with the aid of humor. But also firmly. A superior, or supervisor, or mentor, who always sticks to his guns and does not allow himself to be persuaded is not worth having.

– Prepare to change your mind when new evidence arrives. As has been said, too often it is not old opinions that die; it is those who hold them, still clinging to their antiquated views, who do. This is not a fate you want for yourself and for your work.

– Of all the various ways of learning, none is better than teaching. During my forty-something years of doing so I sometimes felt as if the University, or Israeli society, or God Himself, had created students less because He wanted them to study but in order that my colleagues (those who care about such things) and I might use them as whetting stones to sharpen our ideas on. Feynman in particular provides some good examples of ideas that were first proposed to him by his students. Blessed is the teacher who has students who, rather than just sit there and maybe take notes, will argue with him. Never mind that they seldom form more than a small proportion of the total. Conversely, a student who merely repeats his teacher’s ideas simply repays good with evil.

– When you are stuck, as you are almost certain to be at one point or another in your research, take a break and strike out in a different direction. During the Middle Ages the opportunity to do so was sometimes provided by going on a pilgrimage. Nowadays a visit to some unfamiliar country or culture can often do a lot of good; especially if you take the time not just to ogle a few important “tourist attractions” but to immerse yourself in the culture in question. Operating on a more modest scale a walk or a game, provided it takes your mind off the problem at hand, can do a lot of good.

– Have fun while you are doing it. If you don’t, then you are almost certain not going to get results. So go and seek the company of graves, worms, and epitaphs.

– None of the above is to suggest that the books in question are perfect. As the title indicates, ‘Surely You Are Joking’ in particular bristles with jokes, practical and not so practical, the author has played on his fellow scientists at one point or another. Not only were some of the jokes childish, but at times I could not help but feel that he was trying to boost himself at the expense of others. Hardly a very attractive thing for anyone, let alone a famous professor, to do.

Good luck.

Dvora and I have a grandson. Only child of Efrat and Jonathan, he is called Avishai, a Biblical name meaning “my father’s [or God’s] gift.” Like all grandchildren he is the cutest little boy in the world. With unruly blond curlers and mischievous eyes that are almost always laughing. He loves playgrounds, running about, and ice cream. And chocolate balls too! He is a chatterbox who even as he adds new words to his already quite extensive vocabulary sometimes finds his thoughts outrunning his ability to express them, causing a slight but touching stammer. In a few weeks he will be four years old.

For those of you who are not familiar with the geography of this country, the answer to your question—is his life in any great danger owing to the war—is no. The distance from Gaza to Rehovot where Avishai and his parents live is about 54 kilometers. Their flat is located on the 12th floor of a high rise building. Not only is there no way they can reach the ground floor on time, but there is no point in trying to do so; the building does not have an underground shelter. Instead the flat is provided with a reinforced room that will hopefully protect its inhabitants against anything but a close hit.

But that does not mean that, both in Rehovot and elsewhere, the ongoing hostilities do not make their impact felt. Our oldest grandson, Orr (“Light”) is a junior IDF officer. Though not of the kind where his life is in any greater danger than that of most people here. But three of his cousins, two boys and a girl, are rapidly approaching the age where they will have to reflect about what they are going to do when the call comes as, it surely will. Rehovot itself, located as it is near a major air base, has been attacked many times, luckily resulting in very limited casualties and damage. There and elsewhere other reminders of the war include the rather frequent roar of IsraeIi fighter bombers flying overhead; the somewhat muted atmosphere in what is normally quite a boisterous country; and the growing number of wounded men—hardly any women, fortunately—one comes across in the streets.

When the guns fire, the kids cry. On both sides of the front, mind you. That is why I am posting the following poem, originally written in Hebrew by the late Israeli poet, publicist and playwright Hanoch Levin. But dedicated, on this occasion, to the children of both Israel and Gaza.

O where has my boy gone

My good boy where has he gone?

A black pawn has killed a white one.

My daddy won’t return. My daddy won’t be back

A white pawn has killed a black one.

There’s weeping in the homes, there’s silence on the green

The king is playing with the queen.

My boy won’t rise again. He sleeps, he won’t grow

A black pawn has killed a white one.

My daddy is in darkness, no more will he see light

A white pawn has killed a black one.

There’s weeping in the homes, there’s silence on the green

The king is playing with the queen.

My boy once at my breast is now a cloud of snow

A black pawn has killed a white one.

My father’s kindly heart is now a frozen sack

A white pawn has killed a black one.

There’s weeping in the homes, there’s silence on the green

The king is playing with the queen.

O where has my boy gone

My good boy where has he gone?

All soldiers black all soldiers white fall low.

My daddy won’t return. My daddy won’t be back

A white pawn has killed a black one.

There are no white pawns left nor any black ones

There’s weeping in the homes, there’s silence on the green

The king is playing with the queen.

There’s weeping in the homes, there’s silence on the green

And still the king keeps playing with the queen.

 

You can find the song at https://www.youtube.com/watch?v=d70p5EpwKC0. I have listened to it many times, and each time it makes me want to tear out the few hairs I have left on my head. What have we humans done, what are we doing, to each other! Skip the accords and start at 1.47 minutes.

I Stand Amazed

C. R. Hallpike, How We Got Here: from bows and arrows to the space age (2008).

Until about 10,000 years ago our ancestors lived in small exogamous groups consisting of 25-50 persons each: men, women and children. Inside each group all members were tied to each other by blood or marriage. All were in daily contact with each other, and all were almost indistinguishable in terms of wealth of which, in case, case, there was only as much as peo0le could carry or preserve. Having long mastered fire and learnt to cook food, and armed with stone tools as well as wooden spears and bows and arrows, they roamed over what, to them, must have looked like almost limitless space. As a result, except under exceptional circumstances such as droughts and the like, most of the time they had enough, not seldom even more than enough, to eat. The same factor, i.e the abundance of available space, prevented warfare from doing serious, long-time harm to those who engaged in it. The more so because the normal objective was prestige and revenge, not extermination or permanent subjugation. The last of which, given the way these societies were structured, was impossible to establish in any case.

Fast forward to the early years of the twenty-first century. Our numbers, which 7,000 years ago are said to have reached perhaps 5 million people, have increased to the point where the earth’s population is around 8 billion and growing still. Practically all of them live in millions-strong states where only a very small percentage are related by bloodlines and/or have personal knowledge of each other except, perhaps, in the form of sounds and images emitted by some piece of electronic wizardry. Far from our wealth being equally—let alone, equitably—distributed, we range from penniless beggars always on the verge of starvation to the likes of Jeff Bezos and Elon Musk. In terms of the technology at our disposal we have reached the point where we are now actively drawing up plans for colonizing not just the moon but Mars as well. All this within what in evolutionary terms, let alone geological ones, amounts to a mere blink of an eye.

How could it, how did it, happen? This is the question that Christopher Hallpike, a long retired Canadian professor anthropology who at one point moved to Oxford, took it upon himself to answer. Not that he is the first to do so. One is reminded of the Jacob Bronowski’s The Ascent of Man (TV series, 1973), Bill Bryson’s Short History of Nearly Everything (2003), and Yuval Harari’s Sapiens (2011), among many others. Equating cultural development with biological evolution, almost all of them drew on Darwin as their source of inspiration. With him in mind, almost all started with two basic ideas. First, that cultural change—mutation, to use the language of evolutionists—is more or less accidental, taking place spontaneously now here, now there. Second, that whether or not any innovation persists and spreads depends on how useful it is—the extent to which it makes those who are in charge of it, more comfortable, more powerful and, last not least, wealthier.

By contrast, Professor Hallpike takes it as his starting point that human development, aka culture is not blind. True, some minor changes may have come about more or less by accident. However, he says, for them to persist and to spread there is a need for a conscious effort on the part of both originators and beneficiaries. First, it requires the kind of mind needed to contemplate a new and different reality—precisely the one that, as far as we can see, animals ranging from mosquitos to chimpanzees do not possess. Second, it requires an open society in which different people, coming from different directions and possessing different skills, can meet, exchange ideas, cooperate and, where necessary criticize each other. Third, it requires an investment. If not of money, which only appeared around 600-700 BCE, long after some of the most important discoveries and inventions were made, then at any rate of time and effort. Very often, and this is a point that Hallpike does not emphasize as much as he could and perhaps should have, it also involves taking a risk. The story of the monk Berthold Schwarz inventing gunpowder and being blown up for his pains may not be rooted in fact. Nevertheless, it does present people with a “lesson learnt.”

Another basic point with which Hallpike takes issue is the common belief, famously caricatured by Charles Dickens and his infamous creation Mr. Gradgrind, that it is only material “facts” that either cause change or are affected by it. Standing in front of the blackboard—after all, Gradgrind is a teacher—swish, and away goes religion. Swish, and away goes our senses of beauty, of order, of awe in face of the mysterious and the unknown. Swish, and away go curiosity and inspiration. Swish… Never, so Hallpike, has there been a human society which did not have all those things. Judging by the expression on the face of my cat when he first discovered a new opening we had made in a kitchen wall, even many animals experience some of them.

Finally, judging by his books, including some of his (very funny) fiction I have read, I trust that Hallpike would not have been the man he evidently is, i.e one who loves to play devil’s advocate, if he had overlooked the greatest provocation of all: namely the idea of distinguishing “primitive” from “modern” man. Had he not been long retired, no doubt that alone would have brought on his head severe sanctions on the part of the politically correct thought-control mob. In fact, though, his use of the term is perfectly reasonable. Lacking as they did modern, observation-experimental-mathematically based science, our pre-literate ancestors perforce had no choice but to base much of their understanding of the world on folk wisdom much of which in turn rested on symbolism, religion, magic and intuition as well as every kind of contrast or affinity, real or imagined. It is in this sense, and in this sense alone, that Hallpike calls people and the societies they formed “primitive.” But not once in some 650 pages does he suggest that they were mentally retarded.

I cannot end this essay without noting two other points. First, as an anthropologist who has spent some years living with some of the “primitive” societies he mentions—first in East Africa, then in Papua-New Guinea—Hallpike, discussing such societies, has the immense advantage of knowing exactly what he is talking about. This alone is a good reason for taking what he has to say about them seriously. Second, I find his knowledge of societies, material objects and processes truly incredible; starting with metallurgy—and ending with the history of the alphabet, mathematical notation, alchemy, government, warfare, philosophy, monotheism, astrology and the scientific method there is hardly any field about which he does not have something interesting to say.

The book’s title notwithstanding, its journey through history ends about 1914. As a result, subsequent developments such as relativity, quantum mechanics and chaos theory are mentioned barely if at all. That is a pity; could anyone come up with better examples of sheer curiosity, rather than material gain, driving history into new and unexpected directions? Still I stand amazed. And also, I confess, a little jealous in front of so much knowledge so engagingly presented.
