1979 Dystopian Vision That Came True

I HAVE THIS recurring nightmare. Jonas Salk has just announced his cure for polio. A bill is introduced in Congress to require mandatory inoculation of school children under HEW direction. Opposition then appears. Ronald Reagan urges "free choice by parents rather than compulsion by government." Mobil runs advertisements with the headline, "From gas tanks to bloodstreams. Where will government go next?" An associate professor of economics does a study for the American Enterprise Institute dem...

 Mathematicians as Birds and Frogs

Some mathematicians are birds, others are frogs. Birds fly high in the air and survey broad vistas of mathematics out to the far horizon. They delight in concepts that unify our thinking and bring together diverse problems from different parts of the landscape. Frogs live in the mud below and see only the flowers that grow nearby. They delight in the details of particular objects, and they solve problems one at a time. I happen to be a frog, but many of my best frien...

 Scientific Laws Mean That God has No Freedom

he one remaining area that reHgion can now lay claim to is the origin of the universe, but even here science is making progress and should soon provide a definitive answer to how the universe began. I published a book that asked if God created the universe, and that caused something of a stir. People got upset that a scientist should have anything to say on the matter of religion. I have no desire to tell anyone what to believe, but for me asking if God exists is a valid question for science...

 Chess is the Drosophila of Reasoning

Much as the Drosophila melanogaster fruit fly became a model organism for geneticists, chess became a Drosophila of reasoning. In the late 19th century, Alfred Binet hoped that understanding why certain people excelled at chess would unlock secrets of human thought. Sixty years later, Alan Turing wondered if a chess-playing machine might illuminate, in the words of Norbert Wiener, “whether this sort of ability represents an essential difference between the potentialities of the machine and ...

 The Problem with American Politicians Being Lawyers

The job of the politician in America, whether at the local, state, or naA tional level, should be, in good part, to help educate and explain to people what world they are living in and what they need to do if they want to thrive within it. One problem we have today, though, is that so many American pobliticians don't seem to have a clue about the flat world. As venture capitalist John Doerr once remarked to me, "You talk to the leadership in China, andid they are all the engineers, and they g...

 Four Mertonian norms

The four Mertonian norms (often abbreviated as the CUDOS-norms) can be summarised as: communalism: all scientists should have common ownership of scientific goods (intellectual property), to promote collective collaboration; secrecy is the opposite of this norm. universalism: scientific validity is independent of the sociopolitical status/personal attributes of its participants disinterestedness: scientific institutions act for the benefit of a common scientific enterprise, rather than for t...

 Our Modern Worldview and Morality is Shaped by Science

To begin with, the findings of science imply that the belief systems of all the world’s traditional religions and cultures—their theories of the genesis of the world, life, humans, and societies—are factually mistaken. We know, but our ancestors did not, that humans belong to a single species of African primate that developed agriculture, government, and writing late in its history. We know that our species is a tiny twig of a genealogical tree that embraces all living things and that e...

 Entropy, Evolution, Information (Entro, Evo, Info)

How is entropy relevant to human affairs? Life and happiness depend on an infinitesimal sliver of orderly arrangements of matter amid the astronomical number of possibilities. Our bodies are improbable assemblies of molecules, and they maintain that order with the help of other improbabilities: the few substances that can nourish us, the few materials in the few shapes that can clothe us, shelter us, and move things around to our liking. Far more of the arrangements of matter found on Earth a...

 DNA from the Perspective of a Coder Excerpts

Of the 20,000 to 30,000 genes now thought to be in the human genome, most cells express only a very small part - which makes sense, a liver cell has little need for the DNA code that makes neurons. But as almost all cells carry around a full copy ('distribution') of the genome, a system is needed to #ifdef out stuff not needed. And that is just how it works. The genetic code is full of #if/#endif statements. This is why 'stem cells' are so hot right now - these cells have the ability to diff...

 Health Concerns Spark Adult Interest in Science

Beginning in middle age and continuing through later adulthood, individuals are often motivated by events in their own lives or the lives of significant others to obtain health-related information.^^ Health-related concerns draw many adults into a new domain of science learning. At the same time, with retirement, older adults have more time to devote to personal interests. Their science learnmg addresses long-standing scientific interests as well as new areas of interest.^^ Adults differ fr...
