"There is nothing beyond the world except what we see, no background to it except its particular history."
"We have known since the middle of the nineteenth century that the world is not composed only of particles. ...the world is also composed of fields. ...General relativity is a theory of... the gravitational field. ...Because there are three sets of field lines, the gravitational field defines a network of relationships having to do with how the... lines link with one another. ...This is why we call relativity a relational theory."
"We are the result of processes much more complicated than the small aspects of our lives and societies over which we have some control."
"There are unfortunately not a few good professional physicists who still think about the world as if space and time had an absolute meaning."
"I believe that the main lesson of relativity and quantum theory is that the world is nothing but an evolving network of relationships."
"In the theory of electric fields it is assumed that points have meaning. ...Physicists using general relativity... cannot speak of a point, except by naming some features of the field lines that will uniquely distinguish that point. ...the network of relationships evolve with time... constantly changing."
"The relational picture of space and time has implications that are as radical as those of natural selection, not only for science but for our perspective on who we are and how we came to exist in this evolving universe of relations."
"Since the 1960s, particle theory had been split into two groups: those following the atomism of the quark theory and those who had followed the anti-atomism of that had led from the bootstrap program to the string theory. What happened in 1984 was that it was realised that string theory could combine and satisfy the aspirations of both approaches to fundamental physics. Thus, the community of gauge theorists, driven by the failure of the proton decay experiments to search for new ideas that could unify physics, all of a sudden encountered their old friends, the string theorists, in the middle of what might be called a desert of disappointed expectations."
"The first principle of cosmology must be 'There is nothing outside the universe'. This is not to exclude religion or mysticism... But if it is knowledge that we desire... we need to seek answers to questions about the things we can see... only things that exist in the universe."
"The five big questions in physics 1. How to unify quantum theory and gravity? 2. Does quantum mechanics really make sense? 3. Unify the different forces and particles 4. What sets the masses of the particles? 5. What are the dark matter and energy?"
"Rule I: Except during a measurement, the wave evolves smoothly and deterministically, like a wave on water. ... Rule II: During a measurement of position, the wave collapses around the position where it is seen, with a probability proportional to the square of the height of the wave, before the collapse. ... In fact the two rules seem to contradict each other."
"There is no meaning to space that is independent of the relationships among real things of the world. ...Space is nothing apart from the things that exist. ...If we take out all the words we are not left with an empty sentence, we are left with nothing."
"The geometry of space changes when things in the universe change their relationships to one another."
"Is the flow of time something real, or might our sense of time passing be just an illusion that hides the fact that what is real is only a vast collection of memories?"
"There is no time apart from change. There is no such thing as a clock outside the network of changing relationships. ...one can only compare how fast one thing is happening with the rate of some other process."
"Time is described only in terms of change in the network of relationships that describes space."
"People are people, and all people have emotions and biases, rarely understood: intellectual and emotional behavior don’t necessarily have an inverse correlation. Oppenheimer, as superhuman and wise as he was in so many ways, was still a human being. Depending upon the occasion he could be as human (dramatic, overwhelming, megalomaniacal, self-serving, and even downright dishonest, as his arch-rival Edward Teller was accused of being, and was) as most of us. Like most of us, depending upon the circumstances, he could change his personality and alleged beliefs at the drop of a hat."
"The briefing was over, there were lots of questions that Teller handled with aplomb, knowing far more about the subject than most in the audience. Finally there came a question that had nothing to do with whether or not his bomb was feasible. Instead, it was whether it would destroy the world by causing uncontrollable thermonuclear reactions in the earth’s atmosphere that would cause it to burn up, plus you and me and everyone else. Teller was on his game, as he always was, and replied that he had estimated this terrible possibility and we were quite safe — by about a factor of ten. Now there aren’t too many people who rest comfortably with assurances that mankind’s fate, let alone their own, is on the safe side by a factor of ten, although there are millions of smokers, including myself, drug addicts, sex addicts, who take much greater chances than that with their lives, and they know it. Except that they know it won’t happen to them, which is why many soldiers, at least as stupid as they’re brave, get Congressional Medals of Honor."
"Naturally, the next question was: “How accurate is the nuclear data you used in your calculation?” As only Edward Teller is capable of doing, he replied, with a smirk-smile going from ear to ear: “Well, it’s possible that the data might be off by a factor of ten.” Which way, he didn’t profess to know, but I suspect that much of the audience didn’t sleep too well that night. (If you’re beginning to worry that you might not be sleeping too well from now on, I have to tell you that as it turned out, after careful nuclear measurements and detailed calculations were made, we were safe by far more than a factor of ten. It simply couldn’t happen.)"
"The next day, I called one of them and asked if I could come to his office to discuss the briefing. Fine with him, so off I went. I sat down and asked him a question: “Norm, how did you decide so exactly where the bomb would explode?” He looked at me as if I were a country bumpkin and explained how SAC calculated its bombing accuracy and he had gotten the accuracy of this particular drop straight from the horse’s mouth. Now I don’t want to bore you with how SAC arrived at planning estimates for the delivery accuracy of its nuclear bombers, except to say that it was a statistical process based on thousands of practice sorties, whose results would be mathematically analyzed to allow estimates to be made of the results of a large bombing campaign; not one bomber flying over one city and one bombardier, with the lives of perhaps millions of Muscovites at his fingertips, dropping one bomb. This I pointed out to Norm, implying that he had gone to all that fuss and bother for naught. His response was that in doing his calculations as a mathematician, he was going by the accepted ground rules. The bombing accuracy he had assumed had been provided to him by others. His was not to reason why."
"Teller’s irascible behavior forced him out of the mainstream but not out of the lab, thanks to Oppenheimer who didn’t think we should be without geniuses, even those whose enormous egos caused serious friction. As bright and innovative as Teller was, his overall performance during the war left a lot to be desired. He was not content to be part of a team effort (like yours truly) and preferred to work off to the side on new and different and sometime pretty far-out ideas (like yours truly). This caused considerable resentment. After all there was a war going on and most people thought future nuclear weapon concepts should be worked on sometime in the future, after we had finished our primary assignment. Edward’s behavior was like a colonel on a planning staff during a military campaign who tells his commanding general that he’d like to plan for the next war. That would be the end of the colonel, who would be demoted and shipped off to some base in the Aleutian Islands. Oppenheimer, however, realized that guys like Teller, despite their shortcomings, were necessary to have around; one never knows when a guy like that can be worth his weight in gold, which to the best of my recollection never happened with Teller. So an arrangement was worked out where Teller and a handful of like-minded theoretical physicists, willing to put up with his domineering ways, formed a small group dedicated to doing what they pleased, realizing their efforts stood precious little chance of impacting on the project. The one idea dearest to Teller’s heart was the H-bomb. He and a couple of his cronies applied themselves to devising various schemes on designing such a weapon. All of them turned out to be impractical and most of them unworkable. Which never slowed him down in the slightest for reasons we’ll never know nor will he. I’ve known Edward for a very long time and although I’ve never known him well, one thing about him became clear to me from the very beginning: he was a creature possessed. By what? Again, who knows? Many, if not most, who have read about his life and what he has done, plus those who have known him directly and observed him close at hand and at great length, would say by Satan (which has been said all over the world about me). I wouldn’t go along with that and although I have seen Teller give some of the most impassioned statements morally defending his positions, some of which I have found deeply moving and thoroughly convincing, I would not say that the God I’ve been told exists has had a tight hold on him. If Edward has been possessed by anyone it’s been himself. I’d say the same for myself, and I’ve given you some reasons why, but hardly all of them. I don’t know all of them and would be ashamed to tell you if I did."
"Knowledge or no knowledge, the intelligence community is obliged to furnish estimates to military planners, even if they’re worthless and very possibly misleading. If you are one of those strange ducks trying to understand what this nuclear business is all about and read the “respectable” journals the CIA leaks information to, please don’t get the idea this makes you a more respectable arm chair analyst than anyone else."
"He was all in favor of fighting an all-out thermonuclear war that might devastate a fair fraction of civilization, to settle an argument with the USSR, but was dead set against using discriminate nuclear weapons that could settle arguments on the battlefield without devastating everything in sight. Genius, when applied to human problems, can manifest itself in strange ways."
"As you can well imagine, any nuclear bombing study that neglected to target Moscow would be laughed out of the room. (That is, no study at that time; 10 or 15 years later senior policy officials were debating how good an idea this might be. If you wiped out the political leadership of the Soviet Union in the process, who would you deal with in arranging for a truce and who would be left to run the country after the war?) Consequently, two of RAND’s brightest mathematicians were assigned the task of determining, with the help of computers, in great detail, precisely what would happen to the city were a bomb of so many megatons dropped on it. It was truly a daunting task and called for devising a mathematical model unimaginably complex; one that would deal with the exact population distribution, the precise location of various industries and government agencies, the vulnerability of all the important structures to the bomb’s effects, etc., etc. However, these two guys were up to the task and toiled in the vineyards for some months, finally coming up with the results. Naturally, they were horrendous. (Harold Mitchell, a medical doctor, an expert on human vulnerability to the H-bomb’s effects, told me when the study first began: “Why are they wasting their time going through all this shit? You know goddamned well that a bomb this big is going to blow the fucking city into the next county. What more do you have to know?” I had to agree with him.)"
"5. He changed the title of his book Shame: Confessions of the Father of the Neutron Bomb to Fuck You! Mr. President after the U.S. under George W. Bush dismantled its neutron bombs."
"I have been surprised at the unanimity with which the notion of the unacceptability of a Doomsday Machine is greeted. I used to be wary of discussing the concept for fear that some colonel would get out a General Operating Requirement or Development Planning Objective for the device, but it seems that I need not have worried. Except by some scientists and engineers who have overemphasized the single objective of maximizing the effectiveness of deterrence, the device is universally rejected. It just does not look professional to senior military officers, and it looks even worse to senior civilians. The fact that more than a few scientists and engineers do seem attracted to the idea is disquieting, but as long as the development project is expensive,even these dedicated experts are unlikely to get one under way."
"The unacceptability of the Doomsday Machine raises awkward, unpleasant, and complicated questions that must be considered by both policy maker and technician. If it is not acceptable to risk the lives of the three billion inhabitants of the earth in order to protect ourselves from surprise attack, then how many people would we be willing to risk? I believe that both the United States and NATO would reluctantly be willing to envisage the possibility of one or two hundred million people (i.e., about five times more than World War II deaths) dying from the immediate effects, even if one does not include deferred long-term effects due to radiation, if an all-out thermonuclear war results from a failure of Type I Deterrence. With somewhat more controversy, similar numbers would apply to Type II Deterrence. (For example, some experts would concede the statement for an all-out Soviet nuclear attack on Europe, but not if the Soviets restricted themselves to the use of conventional weapons.) We are willing to live with the possibility partly because we think of it as a remote possibility. We do not expect either kind of deterrence to fail, and we do not expect the results to be that cataclysmic if deterrence does fail."
"I don't want to live in your world in which 1 percent of the children are born defective."My answer was rather brutal, I fear. "It is not my world,"
"Even though it is the ultimate in Type I Deterrence, the Doomsday Machine is an unsatisfactory basis for a weapon system. It is most improbable that either the Soviet or U.S.governments would ever authorize procuring such a machine. The project is expensive enough so it would be subject to a searching budgetary and operational scrutiny—a scrutiny which would raise questions it could never survive."
"(The emphasis is deliberate. This deterrent is more efficient since in most practical cases deterrents destroy populations—not decision makers.)"
"Here is another form of deterrence which, while not a Doomsday Machine, is still an"ultimate" of a sort. This could be called the Homicide Pact Machine, an attempt to make a failure of Type I Deterrence mean automatic mutual homicide. The adherents to this somewhat more practical device hope to divide the work of deterrence in a natural way: We destroy the enemy and the enemy destroys us, neither of us cheating by buying any effective Counterforce as Insurance for our respective societies. The Homicide Pact Machine is clearly more satisfactory to both humanitarians and neutrals than the Doomsday Machine and both should make the distinction."
"The Doomsday Machine is not sufficiently controllable. Even though it maximizes the probability that deterrence will work (including minimizing the probability of accidents or miscalculations), it is totally unsatisfactory. One must still examine the consequences of a failure. In this case a failure kills too many people and kills them too automatically. There is no chance of human intervention, control, and final decision.And even if we give up the computer and make the Doomsday Machine reliably controllable by the decision makers, it is still not controllable enough. Neither NATO nor the United States, and possibly not even the Soviet Union, would be willing to spend billions of dollars to give a few individuals this particular kind of life and death power over the entire world."
"However, even those who expect deterrence to work might hesitate at introducing a new weapon system that increased the reliability of deterrence, but at the cost of increasing the possible casualties by a factor of 10, that is, there would then be one or two billion hostages at risk if their expectations fail. Neither the 180 million Americans nor even the half billion people in the NATO alliance should or would be willing to design and procure a security system in which a malfunction or failure would cause the death of one or two billion people. If the choice were made explicit, the United States or NATO would seriously consider "lower quality" systems; i.e.,systems which were less deterring, but whose consequences were less catastrophic if deterrence failed. They would even consider such possibilities as a dangerous degree of partial or complete unilateral disarmament, if there were no other acceptable postures. The West might be willing to procure a military system which, if used in a totally irrational and unrealistic way, could cause such damage, but only if all of the normal or practically conceivable abnormal ways of operating the system would not do anything like the hypothesized damage. On the other hand, we would not let the Soviets cynically blackmail us into accommodation by a threat on their part to build a Doomsday Machine, even though we would not consciously build a strategic system which inevitably forced the Soviets to build a Doomsday Machine in self-defense."
"He flips to a drawing of a spindly boy wearing oversized glasses, hugging an ABC primer, and sniffing a daisy. This is the enemy. " The first [mistake] is to assume that he is a sort of cretinoid idiot, who can't see, think, or anything. It might be a fair, if dangerous, assumption that the enemy is at least as stupid as we are.""
"The next picture is a Goliath with four arms, reading a book, lofting a 1000-pound dumbbell, aiming a pistol at a target, painting a picture. The enemy can do everything. "He's a giant, seven feet tall with four arms, each with two biceps. Each arm can, of course, be used simultaneously.""
"He ambles along the platform."Lots of times people say about systems analysis, why don't you guys do an experiment? What the hell are you sitting here figuring things? Why don't you go out and run an experiment? Well we'd love to run experiments,but there are two difficulties. One, in realistic experiments, people get shot down. That's not the major difficulty. We're willing to do it." The audience laughs. "We are. The real difficulty is we're talking weapons which aren't in existence yet.""
"The Russians aren't dedicated world dominationists. You know, they just sort of want it on account of a sentimental way, you know, but not like 'By God, we got to have it!' It just doesn't make sense for them to really push too hard, you know, but just to push easy."
"The final outcome of benevolent, informed, and intelligent decisions may turn out to be disastrous. But choices must be made; dies must be cast."
"The usual image of war today held by many experts as well as most laymen can be summed up in the phrase "orgiastic spasm of destruction," or, "spasm war." Many believe that if one single button is pressed all the buttons will be pressed, and that some 30 minutes or so later missiles will rain enough destruction to terminate the defender's existence as a nation; subsequently, some minutes or hours later, a similar rain of death and destruction will annihilate the attacking nation. Within perhaps an hour or two the war will be effectively over-both combatants having received death blows-with only one question left; "How bad will the radiation be for the rest of the world?""
"Actually, even with tested missiles, results of attacks are not really mathematically predictable. The probability of extreme variations in performance, the upper and lower limits, cannot be calculated accurately. But laymen or narrow professionals persist in regarding the matter as a simple problem in engineering and physics."
"In addition to the obvious dangers, there is another subtle but by no means minor disadvantage to a pure deterrence posture: the threat of mutual suicide is a very uninspiring concept, no matter how logical it may seem. If it happened to involve explicitly the annihilation of all humanity it would also be totally immoral; one doubts if it could long remain an important part of United States policy."
"Even if military advantages were not to be had by deliberately limiting attack to counterforce targets, I suspect that most governments would still prefer to observe such limits. Almost nobody wants to go down in history as the first man to kill 100,000 people."
"Few people differentiate between having 10 million dead, 50 million dead, or 100 million dead. It all seems too horrible."
"As far as patriots and nationalists are concerned, I believe that the Homicide Pact system has many of the same drawbacks as the Doomsday Machine, though not in so extreme a form.The major advantage of the Homicide Pact is that one is not in the bizarre situation of being killed with his own equipment; while intellectuals may not so distinguish, the policy makers and practical men prefer being killed by the other side. It is just because this view no longer strikes some people as bizarre that it is so dangerous."
"The difference between megaton and kiloton is very large, in some ways larger than the difference between kiloton and ton. Megaton weapons are comparable to gross forces of nature, such as earthquakes and hurricanes."
"I use the words "unauthorized behavior" rather than "accident" because we must guard against many types of events— psychopathic or irrational individuals, mechanical or human failure, sabotage, irresponsible behavior, and so on."
"Equally important to not appearing "trigger-happy" is not to appear prone to either accidents or miscalculations. Who wants to live in the 1960's and 1970's in the same world with a hostile strategic force that might inadvertently start a war? Most people are not even willing to live with a friendly strategic force that may not be reliably controlled. The worst way for a country to start a war is to do it accidentally, without any preparations. That might initiate an all- out "slugging match" in which only the most alert portion of the forces gets off in the early phase. Both sides are thus likely to be clobbered," both because the initial blow was not large enough to be decisive and because the war plans are likely to be inappropriate. To repeat: On all these questions of accident, miscalculation, unauthorized behavior, trigger-happy postures, and excessive destructiveness, we must satisfy ourselves and our allies, the neutrals, and, strangely important, our potential enemies. Since it is almost inevitable that the future will see more discussion of these questions, i will be important for us not only to have made satisfactory preparations, but also to have prepared a satisfactory story. Unless every-body concerned, both laymen and experts, develops a satisfactory image of strategic forces as contributing more to security than insecurity it is most improbable that the required budgets, alliances, and intellectual efforts will have the necessary support. To the extent that people worry about our strategic forces as themselves exacerbating or creating security problems, or confuse symptoms with the disease, we may anticipate a growing rejection of military preparedness as an essential element in the solution to our security problem and a turning to other approaches not as a complement and supplement but as an alternative. In particular, we are likely to suffer from the same movement toward "responsible" budgets pacifism, and unilateral and universal disarmament that swept through England in the 1920's and 1930's. The effect then was that England prematurely disarmed herself to such an extent that she first almost lost her voice in world affairs, and later her independence in a war that was caused as much by English weakness as by anything else."
"One guy he argued with was my pal Herman Kahn, who could have won any number of Nobel Prizes, except for peace, had he stuck with science. Instead, like Pauling, he tried to save the world, especially his country, from the effects of a nuclear war he was willing to see fought."
"In college, Herman was determined to show his professors how much brighter he was in their field of expertise, which he was, and which he did to their great annoyance. In the Army, during World War II, he was equally determined to show his brilliance, from the very start at the induction center where the two of us (we were inducted at the same place on the same day) took the Army’s equivalent of an IQ test. Wanting to prove himself, Herman had boned up on every IQ test he could get his hands on. Brimming with confidence he sat next to me, certain he would score 100%, which had never happened before.“Men”, the lieutenant told us, “nobody ever has finished this test, so don’t feel under any pressure to do so. If you give the wrong answers to any of the questions it will count doubly against you, so don’t try and guess. You’ve got 45 minutes to do the best you can. Good luck. Start!” After 20 minutes or so Herman had finished. He rested for a few minutes, checked his answers, and with a few minutes left got up, turned in his paper, and left. A couple of minutes go by and Herman comes rushing back into the room demanding his paper back. “Why do you want it back?”, asked the sergeant. “Because I made an arithmetic mistake on question seventy-four (or whatever number it was) and want to correct it”, said Herman. “Get the hell out of here!”, yelled the sergeant. Herman left. Sure enough he made only one mistake, but that was enough to make him number one in the Army."
"The author of "On Escalation" is revealed not as a detached analyst, nor even as a cynically bemused observer of human folly, but rather as an enthusiastic choreographer of the dance of death. He relishes the obscene pranks he invents and the cataclysmic phantasies he invokes."
