A Welcome to New Readers

June 2, 2009

In the last few days, other sites have directed many thousands of readers to my recent posts on knowledge and learning: How to Understand Everything (and Why), How to Learn About Everything, and A Map of Science.
The learning process I describe led me to focus on what I am persuaded is the greatest technological [...]

How to Learn About Everything

May 27, 2009

My recent post “How to Understand Everything (and Why)” discussed an untaught, integrative kind of knowledge, and why is so important in science and engineering — how it can leverage specialized knowledge and improve the trade-off between bold innovation and costly blunders. I discussed the nature of this knowledge and how it can be applied, [...]

A Map of Science

May 20, 2009

A comment on my previous post reminded me of a wonderful visualization that amounts to a map of the whole of science, generated by citation-based clustering of almost a million papers. The image above is a view of an extraordinarily information-dense representation, not just of connections among fields, but of their content. At 13,566,672 pixels, [...]

How to Understand Everything (and why)

May 17, 2009

In science and technology, there is a broad and integrative kind of knowledge that can be learned, but isn’t taught. It’s important, though, because it makes creative work more productive and makes costly blunders less likely.
Formal education in science and engineering centers on teaching facts and problem-solving skills in a series of narrow topics. It [...]

Mission of Gravity, Part 2

March 18, 2009

GOCE is now in orbit.
There had been some doubt: the previous ESA spacecraft to ride a Rockot went into the Arctic Ocean. But what is it? — see Mission of Gravity (part 1).

For Darwin Day: On the Origin of Genetic Information

February 12, 2009

The ideas that evolved from Darwin’s thought have shaped my thinking for more than 35 years, and a decade later, writing Engines of Creation, I relied on the generality of evolutionary principles as an anchor point for surveying the future of technology. Today, in my home, “Uncle Charles says…” means “Evolutionary principles say…”

In joining the [...]

A Brain Drain to Nowhere

December 19, 2008

Science magazine reports a surprising and important scientific development that has been years in the making: US research faculty now spend an estimated 42% of what they consider “research time” on on pre- and post-award administrative activities — on writing progress reports, satisfying intricate rules for revenue management, working on review boards, and so on. [...]

Reflections on Popper on World Philosophy Day

November 21, 2008

Yesterday was World Philosophy Day (as proclaimed by UNESCO), and the celebration continues today in Palermo. This prompts me to consider what I most like about the views of Karl Popper, the scientists’ favorite philosopher of science.
Popper discusses this in his essay, “Evolutionary Epistemology”, in which he argues that all knowledge develops from an evolutionary [...]
