Freeman Dyson on invention and PhDs

Another interesting bit from the Stewart Brand interview of Freeman Dyson that I quoted from earlier. (Hat tip to Danielle Fong).

Brand: One of the things I got from Infinite in All Directions – it was a delight to me, and I’ve been quoting it ever since – is that you honor inventors as much as scientists.

Dyson: It’s as great a part of the human adventure to invent things as to understand them. John Randall wasn’t a great scientist, but he was a great inventor. There’s been lots more like him, and it’s a shame they don’t get Nobel Prizes.

Brand: Is it the scientists who are putting them down?

Dyson: Yes. There is this snobbism among scientists, especially the academic types.

Brand: Are there other kinds?

Dyson: There are scientists in industry who are a bit more broad minded. The academics look down on them, too.

Brand: Is that a weird British hangover?

Dyson: It’s even worse in Germany. Intellectual snobbery is a worldwide disease. It certainly was very bad in China and probably held back development there by 2,000 years.

Brand: How would you stop this intellectual snobbery?

Dyson: I would abolish the PhD system. The PhD system is the real root of the evil of academic snobbery. People who have PhDs consider themselves a priesthood, and inventors generally don’t have PhDs.

The class lines drawn between people who create new ideas (intellectuals), new things-for-a-purpose (engineers and designers), and things-without-a-purpose (artists) are perpetually fascinating. At some level the three activities are hard to tell apart, yet in practice the three groups can act as thought they are quite distinct. One thing I find striking is that each group has standard stories, endorsed by many but not all members, for why that group’s activities are more inherently worthwhile than the other two groups.

The pleasures of a summer workday

I get to sit in my office, which happens to overlook a lake and park, watching the Canada Geese troop their ever-so-cute goslings around. And I get to see unsuspecting walkers in the park run like the dickens when they’re suddenly attacked by extremely angry and vicious goose parents.

What are the pleasures of a non workday? I get to walk around the lake and park, admiring the ever-so-cute goslings, and running like the dickens when I’m attacked by the extremely angry and vicious goose parents.

Both have a peculiar charm, although the workday version involves much less heart-pounding and adrenalin.

The economics of virtual worlds

It’s not always easy to do repeatable experiments in economics. But a few economists have been exploring the idea that virtual worlds might offer a good laboratory for doing such experiments. A recent article in the magazine of the Federal Reserve Bank of Richmond describes some of the work that’s going on.

The existence of such clear economic behavior has convinced Castronova [an ecoomist at Indiana University] that virtual worlds may — but don’t always — provide venues for economists to learn things about economic activity that they otherwise couldn’t. Traditionally, economists have relied on 1) theoretical models that require perhaps imprecise abstractions and assumptions about human behavior 2) statistical regressions of past economic activity, which may fall short because changing the rules of the game will probably mean changes in future behavior, rendering the lessons from the past moot, and 3) experiments with groups of people in random and control groups, which tend to suffer because of the small sample sizes and unrealistic environments.

[…]

“Given this level of control [in virtual worlds], an easy yet breathtakingly powerful research strategy almost immediately leaps to mind,” Castronova wrote in a 2005 paper. “Build several synthetic worlds in exactly the same way, except for some difference in a variable of interest … attract people into the worlds, sit back, and watch what happens.”

SciBarCamp

Jim Thomas has written a terrific article that captures the flavour of SciBarCamp. Here’s the opening paragraphs:

If you are the sort of person who values a list of speakers, a pre-scheduled agenda and a few printed abstracts, this might not be your idea of a scientific conference either. SciBarCamp bills itself as a ‘user-generated’ gathering of scientists, artists and technologists. On the opening night, world-renowned quantum theorists are lined up alongside local artists to propose workshop topics for the weekend. Quirky titles such as ‘Open Source Drug Development’ and ‘Science Stuff in Second Life’ are scrawled down, pinned up, democratically voted on and assembled into an ad-hoc agenda. Long powerpoint presentations are banned. Interactivity is highly encouraged.

The result has a jamboree feel. One participant brought along a couple of Mars-rover robots for show and tell. Another has parked his solar racing car outside. An ad-hoc citizens’ jury about synthetic biology is followed by a percussive performance of Richard Feynman’s speeches. Physicists and jazz singers lead discussions on whether technology makes us happy. Sci Fi writers seek help on plot details. At the ‘Quantum Mechanics For Ten Year Olds’ session [led by Daniel Gottesman – ed], all questions from the audience receive an appropriately quantum answer of ‘Yes AND no’. Any remaining barrier between speaker and audience dissolves into laughter.

‘It’s a huge improvement on the regular science conference format – those usually suck the life and joy out of these things,’ says SciBarCamper Paul Bloore, a local software entrepreuner. His friend Melina Strathopoulos concurs. ‘Its a literal “confer-ence” where people are actually conferring,’ she points out, ‘rather than just an “attend-ance” .’

Machine replicates itself

RepRap is a project to build a machine that can replicate itself. They’ve just claimed success! Here’s the obligatory parent and child shot:
reprap.jpg

Update: Closer examination reveals some significant caveats. What RepRap makes is its unique pieces. There are other commodity items that need to be added by hand. It looks like there’s a fair bit of both in the finished product. Still, it’s pretty cool.

Excerpts from Clay Shirky’s “A Group Is Its Own Worst Enemy”

Clay Shirky has an excellent essay – “A Group Is Its Own Worst Enemy” – on the problems that befall online groups, and would-be designers of scoial software (my rough otes). Here’s a few choice quotes:

Group structure is necessary to defend the group from itself… Constitutions are a necessary component of large, long-lived, heterogenous groups… As a group commits to its existence as a group, and begins to think that the group is good or important, the chance that they will begin to call for additional structure, in order to defend themselves from themselves, gets very, very high.

People who work on social software are closer in spirit to economists and political scientists than they are to people making compilers.

This pattern has happened over and over and over again. Someone built the system, they assumed certain user behaviors. The users came on and exhibited different behaviors.

Less is different — small groups of people can engage in kinds of interaction that large groups can’t.

Of the things you have to accept, the first is that you cannot completely separate technical and social issues.

the pattern that’s worked the most often, is to put into the hands of the group itself the responsibility for defining what value is, and defending that value, rather than trying to ascribe those things in the software upfront.

Members are different than users. A pattern will arise in which there is some group of users that cares more than average about the integrity and success of the group as a whole…. in all successful online communities that I’ve looked at, a core group arises that cares about and gardens effectively. Gardens the environment, to keep it growing, to keep it healthy… Now, the software does not always allow the core group to express itself, which is why I say you have to accept this. Because if the software doesn’t allow the core group to express itself, it will invent new ways of doing so.

absolute citizenship, with the idea that if you can log in, you are a citizen, is a harmful pattern, because it is the tyranny of the majority.

The world’s best reputation management system is right here, in the brain. And actually, it’s right here, in the back, in the emotional part of the brain… If you want a good reputation system, just let me remember who you are. And if you do me a favor, I’ll remember it. And I won’t store it in the front of my brain, I’ll store it here, in the back. I’ll just get a good feeling next time I get email from you; I won’t even remember why. And if you do me a disservice and I get email from you, my temples will start to throb, and I won’t even remember why. If you give users a way of remembering one another, reputation will happen, and that requires nothing more than simple and somewhat persistent handles.

Collective Remembering

Almost everything any member of the human race has ever discovered has been forgotten. Over time, especially the past few hundred years, we’ve gradually learnt to remember some tiny fraction of what is discovered. But we do so selectively. One interesting aspect of the age of Google and the Internet Archive is that we may start to get a lot better at remembering things.
