ROBERT GALLAGER PHD THESIS

My one effort to combine the two led to a very interesting paper. Personal tools Log in. Have you looked at that? But then you mentioned a contraction in the seventies. I forget what was funding me. So the company almost went bankrupt, partly because of the fact that it was too early for the technology that they were into. It wasn’t that the rest of the world was indifferent because at that time certainly the Defense Department felt it was very important.

How does an organization where everybody has their own personal computers, how do they share data? And that’s just the beginning. One has to understand something about the solid-state technology that goes into that. He wrote Discrete Stochastic Processes , Kluwer, in for graduate students going into the network field. The telephone system at that time was a system where things lasted for 40 years. Gallager in his office on Wednesday, the 19th.

Many of them have very little impact. While that idea was being developed, solid-state theory was coming along. Very much the same as in a university. Some of the courses were somewhat Mickey Mouse courses on the Bell System and things thrsis that, things we had to know but they were slightly less interesting than the more theoretical courses.

What other things were going on? Most of the people doing that were never really interested in militaristic things. We can come up with new technology insofar as a small variation on what we’re already doing. But what quickly became evident in the army was that the systems, the training of the officers, the whole system, just wasn’t ready for such a sophisticated kind of technology.

Part of the same project. When I look back five years, and I see what I was thinking then, and I see what other people were saying then, I realize that nobody understands how those things are going to evolve.

It cost a lot of money to build a large computer system; therefore you wanted to have lots of people use it. The problem is how do you design networks to avoid that problem? The problems have traditionally been the problems of trying to organize very large systems, and trying to organize very large systems where you don’t a robdrt have any organizing principles.

So, it was in a sense a failure. I had very little intention of having an academic career at that time.

Of course one had to do something very, very simple from the satellite, and one was very limited in power because you’re going to put large batteries on these early satellites–they were very, very small–and every pound of weight that you put on these things cost an enormous thesiz of money.

People were developing chips.

There were a lot of ideas around for doing that. I was at a meeting yesterday down in New Jersey where we were working on all-optical networks. Five years in the future, probably not. The thing which is important is trying to understand what’s fundamental about a problem.

He started Linkabit which became quite a large company, and now he’s started Qualcomm which is doing very interesting work in the cellular communication area. There were certainly a lot of workers in Europe fairly active at that time. I didn’t want to build things particularly fallager, but I was just troubled by the fact that we were putting so much effort into this one problem, the reliable data transmission, when it seemed as if there was much more need for robedt communication at the time.

That close-knit community in fact became a much larger community as time went on.

You don’t think gaallager of time to say, what’ll I do if this person screws up? For a while I was the only information theorist at MIT. I had the opportunity to sit down with Bob Gallager and ask him about his work, his experience at MIT, and his thoughts on the nature of research and his field. With burst-noise channels, you don’t have this regularity, and therefore you have to find ways of spreading the coding constraints over a much longer period of time.

Every once in a while you see things starting to grow up which might provide a liaison, but the computer field changes so fast–I mean, the technology changes so fast–that somehow the understanding never seems to have a chance to catch up. Zadeh Robert Metcalfe George H. Being able to step back from the details, stepping back from the particular things which are necessary in an implementation today because of the devices we have today for building things, and understand what’s important about building a system.
