Some Remarks on Getting Creative Ideas

As you know the Festival of Thinkers held now for the second time was      All of us at that little discussion were impressed by the similarity of

the world to teach creative thinking to their employees and so on and      this process, saturation - that is filling your mind with the problem,

        by assigning a value of this number “i” of five halves, that way this        each other. In fact they can get mixed up with each other in a big

        have to decay slowly by the weak interaction and this is what people         going very fast. Well that was a very fundamental belief that there
        had observed.                                                                was such a thing as space and such a thing as time and they were
                                                                                     different and they were absolute. And Einstein realized that it wasn’t
        But then it occurred to me that I forgotten about electromagnetism,          necessary, just the way this idea about i and j was unnecessary so it
        electromagnetism could cause these particles to decay even if they           was unnecessary to have absolute space and absolute time although
        had i = five halves and rather quickly because electromagnetism              everybody believed in them he just threw them away. In other words
        interaction isn’t that weak it is fairly strong. So I gave up on the idea.   he was asking why not get rid of them. Why not get rid of absolute

        Jersey, where Einstein worked, in fact he was there at that time. I
        used to see him everyday and say Good morning Professor Einstein             Then let’s go back now to some more experiences that I had. I
        and he would say Guten Morning back and that was about my total              proposed that protons and neutrons the constituents of atomic nuclei,

        explain the idea and why it wouldn’t work. So I did that and I started       named quarks. Well nobody believed that. There were three things
        to explain the idea and then I got to the point where I was going to say     wrong with it people thought – 1) everyone knows that the neutron
        i = five halves and for some reason I didn’t say i = five halves I said i    and proton are elementary they are not made up of smaller things 2)
        = 1. Now everybody knew that these particles as I mentioned before           everybody knows that the electric charge of a particle has to be a
        would have to have half integral values of i, not 1, but half, three         whole number multiple of the electric charge of the proton – so =1,
        halves, five halves etc. but I said i = 1 by a slip of the tongue and then   0 – 1 but not two thirds and minus a third but that was the electric
        I stopped talking because I suddenly realized two things. If it was i =      charge of the quarks, two thirds and minus a third 3) the quarks are
        1, then there wasn’t any problem, I had explained the phenomenon             stuck inside particles like the neutron and proton you can’t pull one
        and second this idea that i would have to be half integral if j was half     out singly to use it in industry there is no quarkonics industry. You
        integral was simply wrong. Everybody believed it, but there was no           may have noticed that. There are a lot of big buildings around here
        reason to believe it - it was just as superstition. So I stopped the talk    a lot of them constructed in the last week. But none of them are
        and I said oh by the way with i = 1 it works.                                a quarkonics factory and the reason is that these quarks cannot be
                                                                                     extracted singly from particles like the neutron and proton - they are
        Now, there’s something we can talk about at a much higher level              stuck inside. Well that’s another thing that people found impossible.
        involving Einstein himself, years and years earlier when he was              So, three notions had be thrown away in order to accommodate the
        working in Switzerland in 1905 and he proposed special relativity.           quarks - the notion that the neutron and proton and so forth were
        You know, special relativity included this famous formula E=mc 2,            elementary, the notion that the electric charges had to be 0, 1, -1 and
        the rest mass of an object, m, corresponds to a storing of energy            so on and not fractions and the notion that particles couldn’t be stuck
        proportional to m , energy given by mc 2, where c is the velocity of         inside familiar objects they could come out – well they can’t in the
        light. Here’s how he did it, I don’t have a transparency but you can         case of the quarks.
        see how he did it. E=ma 2 that didn’t work E=mb 2 that didn’t work
        and then E= mc 2 that was it.                                                Well the quarks turned out to be correct all of those three ideas that

people had turned out to be wrong. In many cases it is worthwhile         occasionally asking why not will lead you to a new business practice
to ask why not. Why not get rid of absolute space and absolute time       which could be very useful. An example of a good reason why not as
if that is what you seem to need? Why not have quarks that are            an example of that I said in business we have profit and loss and that
stuck inside neutrons and protons and can’t be pulled out singly to       is always important and what about legal and ethical considerations,
be used industrially? Why not have particles with fractional charge?      we always have legal and ethical considerations. Now what was
Why not say that the neutron and proton are composited instead of         the company? Who can guess what the company was? Remember
being elementary and so forth.                                            profit and loss and legal and ethical considerations – Enron! They
                                                                          had ignored profit and loss and they had ignored legal and ethical
Now usually there is a good reason why not, but not always.               considerations. They should have listened to my talk more carefully.

        Take an example, a very well known example and exercise that                 could do it with one line. Not by folding the paper or crumpling it – I
        illustrates the point. I think probably all of you have seen this exercise   used a fat line! Like this. See the fat line. Actually you need a very fat
        or heard of it. You draw this diagram with nine dots in three rows and       writing apparatus,
        three columns and you are told to connect all the dots and by drawing

        turns out to be very easy to do with five straight lines, but actually it    PS It doesn’t say you can’t use a fat line.
        can be done with 4 straight lines. Here is how you do it. Four straight
        lines you start here, four straight lines. And you have connected all        That’s the important thing does it or doesn’t it say you can’t use a fat
        of them and you haven’t taken your pencil off the paper. Why do              line?
        people find it so hard to find the example with the four straight lines.
        The answer is they have given themselves an extra rule which is that         Well as you see these ideas are in no way contradictory to Edward but
        you have to stay inside the box. You have to go outside the box. This        they are supplementary to his ideas and they may throw some light
        is probably where the expression outside the box originated I would          on getting creative ideas.
        guess so anyway. At the Sante Fe institute we have a cartoon on our
        bulletin board showing a man next to a cat the cat is standing in            Question from the floor: You have mentioned that you used to see
        a box of kitty litter and the man is shaking his hand at the cat and         Einstein every morning can you just give us an idea what he was
        saying never never think outside the box. So, problem formulation            like?
        is critical, do we really have to stay within the box not necessarily        No
        in our particular case and in that case we can do it with four lines.        You didn’t like him?
        What about other assumptions. Do the dots have to be treated as              No I can’t. If I had it to do it over again, I would probably talk with
        mathematical points, in fact as you see they are not they are little         Professor Einstein - make an appointment to see him in his office

        to use the thickness of the dots? What about crumpling the paper?            any more. The work he was doing wasn’t that great. If I had been

        pencil through the crumpled paper so it passes through the dots. That        of course, I would have talked to him a lot. But as it is, it was just a
        way you are doing it with one line. How do we know? We have to               matter of cultivating him in order to talk about the past and I hated
        figure out what are the real rules for the real problem? A 10 year old       people who did things like that. People who would zero in on a

went to university. He wasn’t the greatest physicist that had ever
lived but he was a very good teacher. He was born I think in the
US of German parents and he had a thick German accent. He was
a native product. He taught a course and it was a very important
course because he did not show the proper respect for the difficult
subjects that he was teaching. He was teaching us about quantum

        My name is Nadia, I was in the panel discussion yesterday sitting next        many of the people who have told you that universities have too

        to be a beneficent member not only to our country but to the world            to culture interdisciplinary research and all of that is true. On the

        I thought Murray Gell-Mann told you about the kind of institute that
        you should make. I have no specific ideas of the nature of an institute.      Question from the floor: I would like to get a closing from you. We

        you should have. You, the citizens of the UAE, will decide what kind          questions about subjects that I do not understand. I would wish that

Good afternoon, Ladies and Gentlemen:                                     optimistic that it will contribute to the formation of global connections

we will be able to address the problems and issues successfully.          Thank you.

During your discussions, you have agreed, I believe, on two basic
concepts. One, the role of thinkers and innovators in shaping
the future of the world will continue to grow. Two, regional and
international cooperation is essential to the growth of knowledge and
solution of problems.

It is now clear that your work, as thinkers and intellectual leaders,
must not only be about knowledge and ideas, but it must also be about
leadership – the leadership required to assure the wise, effective,
and humane use of knowledge and ideas. To achieve that, we must
create and maintain institutions that foster and support creativity,
knowledge, intelligent and informed debate, effective mechanisms
for change, and above all, capable leadership.

When I spoke two days ago at the beginning of the festival, I mentioned
the need for a global community of thinkers, for combining thought
with action, and for promoting equal opportunities for success around
the globe. We’ve made great progress at the festival in focusing
attention on these fundamental issues.

I am hopeful that in the future the Festival of thinkers will become
an influential forum for sharing ideas and analyzing problems. I am
