Individual curiosity, often working without practical ends in mind, has always been a driving force for innovation.

Things that people learn purely out of curiosity can have a revolutionary effect on human affairs.

A good scientist is a person in whom the childhood quality of perennial curiosity lingers on. Once he gets an answer, he has other questions.

But more than 15 sections in Chapter 8 of the report-the key chapter setting out the scientific evidence for and against a human influence over the climate-were changed or deleted after the scientist charged with examining this question had accepted the supposedly final text.

It required unusual inquisitiveness to pursue the development of scientific curiosities such as charged pith balls, the voltaic cell, and the electrostatic machine. Without such endeavors and the evolution of associated instrumentation, initially of purely scientific interest, most of the investigations that lead to the basic equations of electromagnetism would have been missed. ... We would have been deprived of electromagnetic machinery as well as knowledge of electromagnetic waves.

The trouble is that you won't get the scientists to agree on a course of action. It is almost instinctive in science to accept contrary views, because disagreeing gives you guidance to experimental tests of ideas - your own and those offered by others...

This treaty [Kyoto] is, in our opinion, based upon flawed ideas. Research data on climate change do not show that human use of hydrocarbons is harmful. To the contrary, there is good evidence that increased atmospheric carbon dioxide is environmentally helpful...agreement would have very negative effects upon the technology of nations throughout the world, especially those that are currently attempting to lift from poverty and provide opportunities to the over 4 billion people in technologically underdeveloped countries.
