Technology is driving the innovation. Technology is driving the creativity. Technology and the use of that is going to determine our workers' ability to compete in the 21st century global marketplace.

Investing in industries and technology for the 21st century generates high-skilled high-wage jobs for industries of the future.

If we invest in researching and developing energy technology we'll do some real good in the long run rather than just making ourselves feel good today. But climate change is not the only challenge of the 21st century and for many other global problems we have low-cost durable solutions.

There was a study done in the early 20th century of all the entrepreneurs who entered the automobile industry around the same time as Henry Ford there were something like 500 automotive companies that got funded had the internal combustion engine had the technology and had the vision. Sixty percent of them folded within a couple of years.

I am fascinated by all the new technology that creates places for us to meet in what is called cyberspace. I understand what it must have meant for the rebellions in the 19th century especially in 1830 and 1848 when the mass circulated newspaper became so important for the spreading of information.

The telephone is a 100-year-old technology. It's time for a change. Charging for phone calls is something you did last century.

Without any doubt at all teacher quality is the fundamental differentiator. Not just incidentally of education but I would argue probably the biggest single differentiator of success for the nations of the 21st Century.

It's hard for me to think of others because I'm not particularly in sympathy with the music of this century.

We all know that Social Security is one of this country's greatest success stories in the 20th century.

I think that we had a different view of what the 21st century could be like with much more of a sense from our perspective of trying to have an interdependent world: looking at solving regional conflicts having strength in alliances operating within some kind of a sense that we were part of the international community and not outside of it.

In the 18th century James Hargreaves invented the Spinning Jenny and Richard Arkwright pioneered the water-propelled spinning frame which led to the mass production of cotton. This was truly revolutionary. The cotton manufacturers created a whole new class of people - the urban proletariat. The structure of society itself would never be the same.

Although images of perfection in people's personal lives can cause unhappiness images of perfect societies - utopian images - can cause monstrous evil. In fact forcefully changing society to conform to societal images was the greatest cause of evil in the twentieth century.

It was a shock to people of the nineteenth century when they discovered from observations science had made that many features of the biological world could be ascribed to the elegant principle of natural selection.

It is a shock to us in the twentieth century to discover from observations science has made that the fundamental mechanisms of life cannot be ascribed to natural selection and therefore were designed. But we must deal with our shock as best we can and go on.

The birth of science as we know it arguably began with Isaac Newton's formulation of the laws of gravitation and motion. It is no exaggeration to say that physics was reborn in the early 20th-century with the twin revolutions of quantum mechanics and the theory of relativity.

I'm really convinced that our descendants a century or two from now will look back at us with the same pity that we have toward the people in the field of science two centuries ago.

The most exciting thing in the twentieth century is science.

Pure phenomenology claims to be the science of pure phenomena. This concept of the phenomenon which was developed under various names as early as the eighteenth century without being clarified is what we shall have to deal with first of all.

Drill everything mine everything roll back regulations tweak the science expedite permits. Sound familiar? The Republicans offer up more 19th-Century solutions to our 21st-Century energy problems.

In the post-enlightenment Europe of the 19th century the highest authority was no longer the Church. Instead it was science. Thus was born racial anti-Semitism based on two disciplines regarded as science in their day - the 'scientific study of race' and the Social Darwinism of Herbert Spencer and Ernst Haeckel.

Everything is becoming science fiction. From the margins of an almost invisible literature has sprung the intact reality of the 20th century.

Of all the failed technologies that litter the onward march of science - steam carriages zeppelins armoured trains - none has been so catastrophic to prosperity as the last century's attempt to generate electricity from nuclear fission.

Biology is now bigger than physics as measured by the size of budgets by the size of the workforce or by the output of major discoveries and biology is likely to remain the biggest part of science through the twenty-first century.

Almost everything that distinguishes the modern world from earlier centuries is attributable to science which achieved its most spectacular triumphs in the seventeenth century.
