§1. Engineering as problem-solving: the department head's charge [00:03]
Being an engineer is solving problems. In my case as department head, I had a problem. We weren't building a building, we weren't designing a computer chip — we were designing a collegial department. Being an engineer involves complexity, ambiguity, uncertainty, safety, and everything else. And what's the everything else? In this case, the thing that was destroying collegiality within the department. There were wars between the chauvinists and the anti-chauvinists. In fact, that was the charge I was given when I was selected as department head: to improve collegiality in the department. And I did, because it was terrible.
I basically used the scientific method — collecting data, developing hypotheses. The hypothesis about African-American PhDs was that there's only one in the country each year, and how was I going to hire that person. Actually I did hire one of those. He was in his second year of graduate school here, and he wanted to go to work in industry, and I convinced him over the next two years that he actually wanted to be an academic.
§2. Boeing's durable qualities and the definition of engineering [01:34]
Boeing about twenty, twenty-five years ago got their people together and came up with a list of durable qualities all engineers should have. So if we want to say what is engineering, this is not necessarily a definition of engineering, but it's a definition of the attributes of a good engineer. This is what Boeing would like to hire: someone with a good grasp of the science and engineering fundamentals — and we do a pretty good job of teaching that at MIT.
A good understanding of the design process — i.e., understand what engineering is. Design: taking something that didn't exist and creating it, not from nothing but from other components. There was a quote that says engineers don't want to create something new, they want to take the things that already exist and put them together in a new way. A basic understanding of the context in which engineering is practiced — these are all the externalities. Economics: remember the quote, an engineer does something for one dollar that any bungler could do with twenty-two dollars. History — why am I giving you all this history? Well, if you don't understand the context of how you got to where you are, you're not going to solve the problem.
There's a famous quote from George Santayana. Anybody know who Santayana was? He was a philosopher at Harvard, and he's the one who said those who cannot remember history are condemned to repeat it. I have seen many people repeating history in my life because they didn't know what other people had done before them, or they didn't respect what people before them had done. The manufacturing process: you can design some product, but it has to be manufacturable. And then understanding customer needs, which is marketing. These are all things that an economist would call externalities. These are some of the things that Boeing listed when they got a bunch of their managers who had been engineers. These are the types of people they wanted to hire: people with good communication skills — written, verbal, graphic, and listening. Why do we have a writing program and all these other things for undergraduates at MIT? And the ability to think critically and creatively, independently and cooperatively. I handed out that book Thinking Fast and Slow, and one of the topics is creative thinking. Their flexibility and ability and self-confidence to adapt to rapid major change — we haven't gotten into that directly yet — and a profound understanding of the importance of teamwork.
Now there's another definition: engineering involves the application of scientific and mathematical principles — that's the same thing as the first Boeing item. Design — that's the second Boeing item. Design, construction, and operation. So it's not just design. Engineering involves constructing things, whether it's manufacturing, whether it's a bridge or a building if you're a civil engineer, and operation of things like nuclear reactors or whatever. Design, construction, operation of structures, equipment, systems in an economic, efficient, and socially responsible manner. I like this quote because I wrote it twenty years ago. It's part of a report that I was chair of, this committee for hiring and promotion of faculty interested in Big E engineering.
§3. Big E engineering and integrative vs. deductive reasoning [05:42]
Big E engineering came out of, we mentioned the LFM program — that was Big M manufacturing. Well, people started talking about Big E engineering, taking a bigger, broader view of engineering than just the narrow view of analyzing some little component on a carburetor and how to make it better. I did a survey of laboratory directors and department heads and a few deans when I was writing this report. One of the questions was: how much do we need to improve the deductive type of reasoning that we teach the students, or how much do we have to have more inductive reasoning? Design is really an inductive process, whereas studying how a carburetor works is sort of a deductive type of analysis.
Actually I termed it not inductive and deductive but integrative engineering versus deductive engineering. The consensus — now you have to take it with a little grain of salt, because I was the one who analyzed the responses — but I estimated that people felt about thirty percent of the students' engineering education should be on the integrative aspects of engineering, how do you put the big picture together, as opposed to how do you analyze some detailed component. They said about a third of the time should be on the integrative aspects, which are sort of the design aspects. And then I asked how much time do you think we spend? And they thought we only spent about fifteen percent of time in your education doing that. So we needed to increase the amount of integrative things, and part of the integrative stuff is a lot of these externalities. That report was written twenty years ago and there's been some movement, but not much in how we changed the whole field of engineering here. There's been more change over at the management school than there has been in the engineering school.
§4. The history of engineering: from antiquity to the early American schools [08:20]
The concept of engineering has been around since ancient times, and it talked about engineering as sort of mechanical engineering: pulleys, levers, wheels. In ancient times they didn't have a lot of computer chips, but certainly making computer chips is a big part of engineering today. Modern definition of engineering: exploiting basic mechanical principles. Whoever wrote this for Wikipedia thinks of engineering in terms of the fact that over twenty percent of all engineering degrees are mechanical engineering degrees, and a lot of the others — whether it's petroleum engineering or whatever — those types of engineers are often dealing with mechanical things.
Since this is a course in both Course Two and Course Three, mechanical engineering degrees are over twenty percent of all engineering degrees. In materials there was a study once that even though materials engineers are about 1.2 percent or a quarter percent of all degrees offered in engineering, about twenty-five percent of all people working as practicing engineers are basically acting as materials engineers. If you're a civil engineer and you were selecting the materials to build a new building or bridge, you're basically doing a material selection. They found that thirty-five percent of all other engineers were indirectly involved with materials — so sixty percent of all engineers end up working on materials. And you can say that probably seventy-five percent of all engineers are doing mechanical-type things.
When I was department head and I sat on engineering council, I used to point out Course Three was the only department in the school of engineering that didn't have a materials subgroup. In mechanical, do they still use suds, systems, and solids? They divided the department into the three S's: suds, which is fluids; systems, which is systems engineering; and solids, which is solid mechanics. They had their solids, which was basically a materials subgroup. The head of chemical engineering used to get really upset with me when I said that, but he did have a materials subgroup. Most engineers except software engineers are actually working with materials. Software engineers are working with the computer and bits — they're one of the only kinds of engineers that aren't working with materials.
So let's get into the history. The history of engineering goes back to ancient times, when the Egyptians were building pyramids. That was mechanical engineering, civil engineering, whatever you want to call it. It wasn't easy to build a pyramid unless you had a lot of slave labor, and they did. But even then they had to design it, and they had a lot of mistakes — and that's another theory we'll go through, about how engineering progresses through mistakes.
The first type of engineering school was École Polytechnique in France, and they were military engineers. I don't know enough of the history of École Polytechnique, but apparently Napoleon — although it must have been someone earlier than Napoleon too — supported the engineering because that helped him win his battles. In 1802 West Point officially became the first engineering school in the United States. The US Army Corps of Engineers were in charge of West Point until 1845 before they allowed someone who wasn't an engineer to become head of West Point. In 1824 the Rensselaer school was founded for the purpose of instructing persons in the application of science to the common purposes of life. They had one degree program, and it was civil — and they called it civil engineering to distinguish it from military.
The University of Michigan claims they had a school of engineering in the 1840s. That might be true, but they had four students in Michigan in the 1840s — maybe the bears were signing up, or the raccoons. Civil engineering came about at Rensselaer in 1824. William Barton Rogers started to organize MIT in 1865. Course Two was mechanical engineering, and that was basically how to build machines that made widgets, whether you're talking about handguns — who was the guy who developed interchangeable parts? Eli Whitney was the cotton gin. Colt was a little later. I don't remember my high school history lessons. But some early manufacturing people were designing machines that made interchangeable parts; they made the cotton gin; Cyrus McCormick made the wheat harvester and things like that.
§5. The engineering disciplines arrive at MIT [14:23]
So that was sort of mechanical engineering — wasn't building bridges and stuff. We had a mechanical engineering department. Course Three was mining engineering. Metallurgy had not been invented by 1865. Metallurgical engineering actually came in about 1873 when a guy in England, Henry Clifton Sorby, who had been a geologist, started polishing metals and etching them with acid — that's the beginning of metallography, and that's when people started seeing structure in a microscope in metals. Before that, metals were just metals. Also what came along was people like Andrew Carnegie became the richest man in the world. He was richer than anyone today in constant dollars. Steel made Andrew Carnegie the richest person in the world then, and if he had the same equivalent wealth, he would be the richest man today.
Electrical engineering came in around 1879, 1880. What brought electrical engineering into being, as one student suggested correctly, was Edison and Westinghouse basically developing generators for electric lights. One of them was in favor of AC power and one of them was in favor of DC power. Who won — which was which, Edison or Westinghouse, AC or DC? Edison was DC; he lost. Westinghouse was right. There's a lot of reasons why AC is better than DC, but mostly it's because you could make motors and things much more easily with AC than DC. When you have moving magnetic fields you can make other things move — you can make mechanical things.
Chemical engineering was invented around 1888. Does anyone know where chemical engineering was invented? MIT. Arthur D. Little was one of the chemistry grads at MIT. Chemistry was Course Five, architecture was Course Four at MIT when things started. Arthur D. Little and some other people — you don't really know Arthur D. Little now, but he started the first big engineering consulting firm, and essentially they helped bring the oil business to the world. At one time the CEO of every major oil company in the world was an MIT grad.
Naval architecture, which is no longer a department but is part of mechanical engineering — the 2N program for marine engineering — was started at various places, but around 1893. Aeronautical engineering — where was that invented? Hunsaker. He built the early plane — basically a seaplane, I think — that was the first to fly across the Atlantic, although he did it in hops and skips; he didn't do it continuously. After he finished his flight he came back and started the aeronautical engineering department at MIT, which was the first one.
Nuclear engineering — we have our nuke here today, but she's not here. Where was it invented? MIT. Manson Benedict in 1958 started a department of nuclear engineering, brought some physicists and some materials, mining, mechanical people and chemical engineering — brought a bunch of people together from different departments, and they started looking at how to do things. And then in 1974, the department of metallurgy, which had entered MIT in 1888, changed its name to materials.
§6. Harvard, MIT, and the land-grant story [18:31]
Let's go more specifically to Harvard–MIT. Someone was asking about the fact that Harvard had tried to purchase MIT. MIT wasn't necessarily the third engineering school in the country, because Michigan was educating bears or rodents or whatever, but they were really still doing sort of civil engineering — how to build roads and things like that. But engineering was coming into its own. Lehigh University had engineering, and Tau Beta Pi became the engineering honor society. Why? Because Phi Beta Kappa thought engineering was a lower skill, a lesser art, and Phi Beta Kappa is for the arts and sciences. Engineering was considered to be the work of machinists and draftsmen — what's the arts and sciences in that? So this is the hierarchy of snobbery that I talked about. But engineering was becoming more popular because the United States was going through this Industrial Revolution, and engineers were needed for the building of the railroads and Carnegie steel mills and everything else.
Harvard tried three times starting in 1873 to purchase MIT, and finally in 1917 the Supreme Court of Massachusetts said nope — MIT is a land-grant college. Anybody know anything about the land grant program? Anyone from Illinois here? At the University of Illinois, in the center of campus there's a plot of corn. What's the name of it? Morrill Plot. Morrill was the congressman from Illinois [Vermont], and of course they were involved in the Civil War. This was 1863. William Barton Rogers had gotten the charter to start MIT in 1861, but he had no money, and the Civil War started, and he didn't really have a lot of students either, because they were all going off to get shot.
Morrill decided — and this is the way they built the railroads — the government had a lot of land, they didn't have a lot of money, but they had a lot of land, and so they would give land to the railroads. They basically passed a law that if you built a railroad you would own the land for a hundred yards on either side of the railroad. So the longer your railroad, the longer your driveway — or your railroad. But you had the land, and then people wanted to be close to the railroad, so you had valuable land. That's where the cities and towns built up around railroads. So the railroads became very powerful because of Congress essentially giving them land or rights-of-way if they would build railroads.
Morrill decided they could do the same thing to encourage — it was the Land Grant College Act. If a state wanted to start an agriculture and manufacturing university — there's a number of A&M universities: Florida A&M, Texas A&M, a lot of states have agricultural and manufacturing as title to one of their universities — those typically were the land-grant colleges. Any state could become a land-grant college. William Barton Rogers went down to the State House here in Massachusetts and said, I'm not a state university, but will you give us the land grant act, and we'll get the land from the government, and we'll build MIT. And they did, and MIT is the only private university in the country that is a land grant college. There are fifty land grant colleges, but only one is a private university, and that's MIT.
The reason Harvard finally couldn't buy us in 1917 was because the Supreme Court of Massachusetts said you can't use the land grant charter and transfer it to another private university. But they had been going down that road, and Harvard nonetheless started their own school of engineering. It turns out they built it on land that Andrew Carnegie had given them a hundred thousand dollars to buy, in Allston, right across the river. It's now known as the Harvard Business School. At the time in 1921 when the Harvard Business School opened, there was really no difference between engineering and management. Frederick Taylor, who is the father of industrial engineering, was a faculty member at Harvard Business School in 1921. He did time and motion studies in manufacturing plants to become more efficient — as people would carry bricks from here to there and stuff. He did a lot of this work over at Watertown Arsenal, which is now a mall, but at the time was the US Army manufacturing operation. They were making parts for the military. It was a big factory over there.
§7. The Harvard–MIT merger that almost was, and George Eastman's rescue [23:39]
Between 1914 and 1917, MIT and Harvard had signed an agreement — their third one. MIT was in the throes of building this building you're in. This building was actually not finished until 1917, but officially MIT moved over from Kenmore Square about 1916, and some of these buildings were still under construction. The ones on Mass Ave were ready in 1916. Harvard kind of saw this as: this would be their engineering school down the river, down Mass Ave. But then they couldn't buy it.
Between 1914 and 1917 the students at both Harvard and MIT were getting a degree from both institutions. How about that? That's the way to cut your tuition in half. The idea was they were going to formally merge, and the faculty merged. I know part of this history because the guy who founded the American Welding Society was a professor of engineering at Harvard, and when I had to give a lecture named after him once, I looked up his history. It turns out he was an MIT faculty member from 1914 to 1917. He never left Harvard, but he was an MIT faculty member for three years.
The problem was MIT was expecting the merger with Harvard to solve the problem that MIT was bankrupt from building these buildings. Anybody know what happened to get MIT out of hock? It was the founder of Eastman Kodak — George Eastman. He never married, he never had any children, had a lot of money from founding Kodak, and Building Six is the Eastman Building. He gave six million dollars, which was a huge fortune then — be like a hundred million dollars today. He got MIT out of hock, but he gave it anonymously. They didn't find out until he committed suicide in 1929. When the Great Depression came, he was very patriarchal — he cared a great deal about his employees — and when he saw the whole economy falling apart, he just took his own life. Somewhere in there we learned that he was the benefactor who got us out of hock.
§8. Sloan School versus Harvard Business School [26:17]
Then there was all the science and engineering that helped win World War Two. We talked about that — there's lots written on those things. In 1950 Alfred Sloan of General Motors endowed the Sloan School of Management. Alfred Sloan was an MIT grad. He basically went to Detroit and started merging companies like Chevrolet, Buick, Oldsmobile, Cadillac, Fisher Body, and became very wealthy. A large part of MIT's endowment goes back to Alfred Sloan. He gave a very large fraction of his fortune to MIT, and part of it went to the Sloan School of Management. They took the Department of Business and Industrial Development, which was doing the same types of things as the Harvard Business School. Over time the Harvard Business School moved more towards general management, and MIT Sloan School started out as an engineering school, and the two of them are very different.
In 1988 I took a nine-week special intensive program at the Sloan School, and we were going to have dinner with the Harvard Business School executive education program folks. They came down to MIT Endicott House, and we went up to Harvard, just to get to know each other. One of the guys asked Ed Schein — Ed Schein was a faculty member at the Sloan School, organizational behavior was his specialty — what's the difference between MIT Sloan School and Harvard Business School? And Ed Schein said, well, Harvard is sort of the West Point of business schools, and MIT is sort of the Bell Labs.
That was a perfect description. At West Point they teach you how to do it. You'll study the Egyptian-Israeli tank war of 1973 — how the Israelis wiped out the Egyptians in three days or whatever — and they tell you how it's done. At Harvard they do the case study, and in the case study they're telling you, this is what happened — they're telling you the history of what happened, and you're supposed to figure out how to run a business based on studying the history of mistakes and successes. At the Sloan School of Management, most of the faculty have never been to business school. One time someone did a check, and only twenty or twenty-five percent of faculty at Sloan School had management degrees. Most of them came out of MIT engineering. Sloan is known as having the top programs when it comes to quantitative work — the finance program, the operations research program. Sloan is at the top of some of these areas where you use the mathematical skills and solve the partial differential equations.
§9. Lester Thurow and the lesson in communication [29:38]
One of the other differences: Lester Thurow, back in the late 1980s, became dean of Sloan School. Lester was an economist, but he was in the Sloan School, and his colleagues called him Less than Thorough. But Lester at the time — this is 1988 — was making thirty thousand dollars a lecture, going to someplace like General Motors and talking to their board of directors, giving a one-hour lecture for thirty thousand dollars. Not bad. Sort of like Bill and Hillary going on doing this for two hundred thousand dollars today. Lester was at that level. And being in the senior executives program, listening to him changed the way I did teaching.
Lester came in and gave a first talk to us. This was a nine-week program. After about two weeks he came in to talk to fifty of us, and we were all just enamored with Lester. I mean, how'd he get thirty thousand dollars a lecture? Because he was just an engaging lecturer. He'd get up and he talked without overheads. His notes consisted of a 3×5 sheet of paper, a note card with some little words, about ten or fifteen words written on it — those were the topics he was going to talk about. As a speaker he didn't want you looking at the screen — he wanted you focusing on him. And when he got up, he was just very dynamic. Afterwards everyone in the room: wow, wasn't he great.
The second time he came in, about four weeks later, everyone else was just listening to him. I'm the engineer — I'm sitting there: what is he doing, how is he doing it? And at the end of his second talk I thought he didn't say anything I didn't already know. Most of what he said was very simple, but it was the way he said it. This is the communications thing. He was making a lot of money for communicating things well. To give you an example: I heard him a couple years later. He was still dean of Sloan School, and he was over at the Cambridge Marriott Hotel, giving a talk to a bunch of Sloan School alumni. He was lamenting the fact that the big rich business school up the river would come in and hire some of our best business school faculty. This was one of his biggest problems as the dean of the Sloan School — trying to hold on to some of the Sloan faculty.
Anybody know about the pay scales of faculty at MIT and most other universities? The people in humanities make half of what they do in engineering or science, and the people at Sloan School make twice what they do in engineering or science. I'm not kidding. So there's a factor of four difference in scale. You want to be a professor of music, you can make a little bit more — maybe not quite as much as a high school music teacher — as a faculty member at MIT. You might be a great composer, but you're in the humanities, and the competition there is lots of people who want to go study medieval history. There's not a lot of jobs for them. The engineers, we have our pay scale. The management guys have their pay scale, and Harvard's got enough money, they could lure some of those people away. Lester was lamenting that he loses some of these people, and a lot of people knew that one of the people he was talking about was Robert Merton.
Anybody know Robert Merton? Anybody heard of Black–Scholes? Black and Scholes were two faculty members at Sloan, and Merton was the graduate student, and the three of them came up with derivatives. I'm not talking Isaac Newton derivatives — I'm talking about derivatives as in trading. Predicting the value of stock in the future based on the volatility and the current price of the stock. They had a mathematical formula — it's typical MIT, you could write down a specific formula and you would get a specific number of what the value of that stock is today based on its past history and mathematical variations in the price. That's calculus stuff. That was called derivatives. It was Black, Scholes, and Merton.
Black and Scholes passed away, and Merton got hired away to go up to Harvard Business School. A couple years later Merton won the Nobel Prize. Black and Scholes didn't get it because they were dead. That's why Harvard hired Merton away — he was obviously going to become a Nobel laureate, and he did. There's other people, like Paul Krugman — wasn't at the Sloan School, he's in the Economics Department. Anybody hear of Paul Krugman? I used to like Paul Krugman. He would say things very simply, just like Lester Thurow.
For example, one of the things he said: to live well a nation must produce well. He also said productivity isn't everything, but it's nearly everything, when it comes to economics and production. So he was sort of like Lester — an economics educator. He's on Face the Nation and so on. He left to go to Stanford; now he's at Princeton, back at Princeton. They've talked about Paul Krugman potentially winning the Nobel Prize. But Lester Thurow was lamenting the fact that he lost certain faculty, but he said, fortunately they tend to hire our extinct volcanoes.
Now, do I have to explain what he meant by an extinct volcano? He used metaphors that just made things too obvious. He was the communicator. So that changed my life in 1988. I started thinking, you don't have to have fancy complex things — you just say what everyone knows, but you say it in a way that's memorable. For example, at the time I was still kind of a guru in welding. They held this welding conference every two years in Gatlinburg, Tennessee, because the guys at Oak Ridge would organize it, and I'd been the keynote speaker for the last three conferences. Actually they changed me from being the scientific keynote to being the after-dinner keynote, when all the spouses were there, because I had learned to start talking like Lester.
In 1989 I gave the scientific keynote, and I was talking about resistance welding, which is how they put automobile sheet metal together. I said: they put three thousand spot welds in the average automobile because you need two thousand good ones. I'm trying to make a point about the quality of spot welds and the inability to inspect them. A year later I'm at another welding conference, and it's a little cocktail mixer party, and I hear someone behind me say, you know, they put two thousand spot welds in the average automobile. They were quoting me. Why? Because I said it in a memorable way. If I had just gotten in and started talking about, well, sixty-seven percent of the spot welds are good and we have thirty-three percent bad, who would care? It changed the way I taught. Now I tell stories, because it turns out you'll remember those things. So communication skills are important.
§10. Sputnik, snobbery, and the Walker–Noyes battle [38:39]
There was a big change after 1957 when the Russians launched Sputnik. That was a wake-up call for the United States. We thought we ruled the world in science and technology after World War Two. We did produce seventy-five percent of the world's steel in 1945. Anybody know why? Yeah — we bombed them out. That is the best way to beat your competition: send a B-52 over, bomb them out, they're gone, they won't be selling that product over here. And then twenty-five years later we made twenty-five percent of the world's steel.
Now, going to this snobbery of engineering and how engineering is perceived. This is Francis Walker, the president of MIT in 1891: "Too long have our schools of applied science and technology" — meaning MIT — "been regarded as a [forty] and inferior substitute for classical colleges" — the Princetons, the Yales, the Harvards. "Too long have the graduates of such schools been spoken of as though they had acquired the arts of a livelihood at some sacrifice of intellectual culture or grace of life." They treated us like nerds in 1891, and they still do. And there's part of a reason for that. Some of you are nerds. Some of us are.
William Walker, who was actually one of the founders of chemical engineering — and I think Francis Walker is the one whom Walker Memorial is named after — was a chemical engineer. "There is with scientific men a general awakening to the fact that the highest destiny of science is not to accumulate the truths of nature in a form no one but a select few can utilize, but the search for truth can be combined with a judicious attempt to make the truth serve the public good." There was a question yesterday about the difference between Caltech and MIT, and it gets to this. Walker had a fierce battle with a guy named Arthur Amos Noyes. Arthur Amos Noyes was the greatest physical chemist in the United States. He'd gone over to Germany, got back around 1900 — because that's where everyone studied to become the top scientists. Germany was where the top scientists were until after World War Two.
Noyes became the top physical chemist, and he thought it was an absolute perversion of the academic lifestyle to work with industry. William Walker was head of the MIT chemical engineering practice school, which is held up today as being one of the great things of universities and industry working together, and the two of them had a terrible fight. Noyes happened to rise to be president of MIT, but he still lost the battle of whether you should interact with industry. MIT chose to work with industry. Noyes, having lost the battle, teamed up with a guy named Robert Millikan. Who was Robert Millikan? The Millikan oil drop experiment in physics. He was at the time a professor, I think, at Case Western Reserve University — actually Case Institute of Technology, whatever it was called. Millikan and Noyes went out to Pasadena, California, and they took over a little school called Throop Institute of Technology. This was in the 1920s or so, I believe, and they renamed it — Caltech.
The mascot of MIT is a beaver. What's the mascot of Caltech? A beaver. I've been told the school colors are also the same. But the difference is, Millikan and Noyes were scientists, so they didn't believe in a lot of industrial interaction. MIT grew and has tremendous industrial interaction. They had great engineers at Caltech like Theodore von Kármán, who founded the Jet Propulsion Lab. But Caltech was and is a culture based on science, discovering things, and not necessarily making them serve the public good. How many spin-off companies do you know of, or have you heard of, that had something to do with MIT? A lot of Silicon Valley is MIT. But you don't hear that. You hear a lot about Stanford. How much do you hear about Caltech? Part of it is Caltech is a much smaller school, about one-third the size of undergraduates. But even so, it's partly the culture that goes back nearly a hundred years, to Noyes and Millikan, who were fundamentally scientists who didn't think they had to make their work serve the public good.
So that's the history. Tomorrow — can't remember what we're talking about. I have prepared it, can't remember. Okay, thanks.
