Slide1:  Creativity in Science and Engineering: Sometimes Easier, Sometimes Harder, Than You Expect" Martin L. Perl Stanford Linear Accelerator Center Stanford University Presented at VIPS!-2007 Tokyo June, 2007 Slide2:  TOPICS Creativity in Science and Engineering How to Get a Good Idea Colleagues The Art of Obsession The Technology You Use Future Technology SLAC: A Model for an R&D Laboratory Slide3:  Creativity in Science and Engineering: Slide4:  Creativity Creativity is sought everywhere: in the arts, in entertainment, in business, in mathematics, in engineering, in medicine, in the social sciences, in the physical sciences. Common elements in creativity are originality and imagination. Creativity carries feelings of wide ranging freedom to design and to invent and to dream. But in engineering and science creativity is useful only if it fits into the realities of the physical world. Slide5:  Example of Constraint on Creativity A creative idea in science or engineering must conform to the law of conservation of energy (including the mass energy mc2). If an inventor thinks that they know how to violate the conservation of energy, he or she will have to overcome a vast amount of laboratory measurements and accepted theory. A perpetual motion machine violates the conservation of energy Slide6:  Example of Constraint on Creativity A creative idea in science or engineering must conform to our present knowledge of the nature of matter, unless we invent or find a new form of matter. Slide7:  Example of Constraint on Creativity A creative idea in computer science must obey the laws of mathematics and logic. Slide8:  Observations and Rules of Thumb Your idea may be in an area where the basic science or mathematics is not known, then begin by paying attention to the known observations and rules of thumb in the area. But the observations and rules of thumb may be wrong. Remember when doctors thought that ulcers were caused by spicy food and stress, but now know most ulcers are bacterial infections. Slide9:  Practicality and Feasibility Constraints Creativity in science, engineering and computer science is constrained by feasibility and practicality. Consider the work in the US on a nuclear reactor powered airplane in the 1950’s The reactor was to be in the front and the crew in The rear. Slide10:  How To Get A Good Idea Slide11:  For every good idea, expect to have five or ten bad or wrong or useless ideas Steam powered automobiles Phlogiston model of combustion Everyone will own a flying automobile Lamarckian evolution Homeopathic medicine Astrology Electromagnetic ether Cold fusion Slide12:  Creative engineers and scientists get bad ideas along with the good ideas. Nikola Tesla was a pioneer in long distance wireless, a good idea, but he also thought he could use the same tower to transmit large amounts of low frequency power. Slide13:  Take account of your personality and temperament To get good ideas you must take account of your personality and temperament in choosing your technical field or science and your interests in that field. Be yourself. Creative scientists and engineers have a many different types of personalities Esaki Yukawa Edison Hopper (compiler inventor) Slide14:  Curie Turing Yalow Perelman Slide15:  Backus, FORTRAN inventor Slide16:  Mathematics and getting good ideas Don’t try to fit yourself into any particular image of what a scientist or an engineer should be. You don’t have to be a mathematical genius. There are lots of fields where mathematics is secondary. But you should be competent in mathematics. Slide17:  Hand-on skills, laboratory skills and getting good ideas Evaluate the extent of your hands-on skills and laboratory skills Are you good at working with tools, at building equipment, at running equipment – electronics, microscopes, telescopes ,,,? This is my strength. I am an experimenter in physics. because I like to work on equipment, because I am mechanically handy and because I get great pleasure when an experiment works. But hands-on skills do not have to be your strength. Isadore Rabi, who was my doctoral research supervisor at Columbia University in the 1950’s had no laboratory skills. Yet Rabi won a Nobel Prize for advancing experimental atomic physics. When choosing what you work on in engineering and science honestly evaluate the extent of your hands-on and laboratory skills. Slide18:  Visualization and getting good ideas In engineering and scientific work it is crucial to be able to visualize how the work could be accomplished. The intended work might be the invention of a mechanical or electronic device, it might be the synthesis of a complicated molecule, it might be the design of an experiment to evaluate the efficacy of a new drug, it might be the full modeling of how proteins fold and unfold. Different kinds of work require different kinds of visualization. Spread sheets or flow charts may be best. Drawings might be best. Always, the importance of visualization is to find the best way to proceed and to avoid mistakes and to perhaps find alternative solutions and related good ideas. Do not go into engineering or science if you are do not have visualization ability. Visualization is crucial for creativity in engineering and science Slide19:  Imagination and getting good ideas Imagination is a second crucial ability required to be creative in engineering and science, imagination with the constraints I have talked about: known physical laws, correct observation and experimentation, feasibility, practicality. Begin with the far reaches of imagination at the science fiction level, then apply the constraints gradually. Slide20:  Lone wolf or leader of the pack There are two opposite personality traits that can contribute to getting good ideas. One personality trait is to be a lone wolf, a contrarian in your field. The opposite is to lead the pack of colleagues and competitors. I prefer the contrarian style. If others are successfully developing a new technology I’d rather copy it or buy it. Slide21:  Keep busy between good ideas by computing or designing or building even if it is routine. Slide22:  Keep a notebook. Slide23:  Colleagues Slide24:  In the modern world the highly productive lone engineer or inventor or scientist is very rare. Slide25:  Find colleagues who are smarter than you and know more. I always look for colleagues who are smarter than I am and who know more than I do. The obvious advantages are she or he may be able to solve the problem that has produced a dead end in your work. Most important, smart and knowledgeable colleagues can save you lots of time. Slide26:  You don’t have to be a fast thinker or a fast talker. In fact, it is best to avoid such people as colleagues Slide27:  The Art of Obsession In Computing, Engineering and Science Slide28:  Obsession is important when you have a good computing, engineering or science idea When you are imagining and visualizing an idea that you expect to be fruitful it is important to be obsessed with the idea. Think about the idea as much as possible, neglecting boyfriends, girlfriends, children spouses. Obsession will bring immersion of your mind into all the aspects of the idea: what has been done on related ideas, compatibility with physical laws and mathematics and logic, feasibility, practicality, extensions, variations. Slide29:  But if the course of the work you find that someone has a better idea or that you have run out of money or that the idea has a serious flaw. Give up the obsession and move on Slide30:  The Technology You Use Slide31:  You must be interested in, even enchanted by some of the technology or software or mathematics you use. Then the bad days are not so bad Slide32:  Another advantage of being enchanted by the technology or the programming or the mathematics is that you will be more likely to think of improvements and variations. Sperry Slide33:  You should be fond of the technology or mathematics or programs that you use, but not too much in love with the technology or mathematics or programs. There may be a better way. Slide34:  The Technology of the Future Slide35:  It is often impossible to predict the future of a technology. Some technologies are replaced again and again by new technologies serving the same function Slide36:  It is often impossible to predict the future of a technology. Some technologies persist through incremental improvements The reciprocating gasoline engine is 140 years old Slide37:  Some promising technologies go nowhere My experience in 1950 with the miniature vacuum tube and the transistor Transistor inventors William Shockley (seated), John Bardeen, and Walter Brattain, 1948. Slide38:  I have been unsuccessful in predicting the long term future of technologies Slide39:  SLAC: A Model for an R&D Laboratory SLAC: Stanford Linear Accelerator Center Operated by Stanford University for the US Department of Energy About 1500 staff About 4000 national and international users Facilities for: Elementary particle physics Photon and x-ray physics Astrophysics Accelerator physic Slide40:  SLAC is an Egalitarian Laboratory We have no ‘Herr Professors’. We respect equally the knowledge and skill of everyone at SLAC be they a mathematical physicist thinking about dark energy or a welder skilled in making vacuum systems or a business person who understands the intricacies of federal contracts Slide41:  Flexibility At SLAC we tremendously value individual and institutional flexibility. Our institutional flexibility is the ability of the Laboratory to move into new areas and to fill new national and international science needs. Slide42:  The SLAC Process: 1. Broad openness to new Ideas. 2. Thorough evaluation, experimentation and calculation on the new idea. 3. Careful, open conclusion. One example: in experimental physics research we are broadly open to new ideas, the research is carried our with thorough analysis, but we take great care to make sure we are right before we publish. Slide43:  Practicality SLAC is an ivory tower in a real world but we know that we are supported by the real world. US Taxpayer Congress White House Dept. of Energy Office of Science SLAC Slide44:  Thank You I thank Professor Milutinovic and Professor Fujii for the opportunity to give this talk. I will be grateful for comments and ideas from the audience
