Time and Consciousness?

We live in a world where everything seems to speed up. Everybody is pressed for time; the pressures to perform, to consume, to “manage” time effectively, or to “have fun,” overwhelm our need for rest and contemplation. Will the future bring us even more acceleration? Are we going somewhere with all this change? And further: what is our relationship to time itself? Can we become more conscious of the flow of time and thereby separate ourselves from the addictive absorption in current affairs?

At the root of the last 500 years of scientific and intellectual history lie the abstractions of space and time. The progress we witnessed over the last centuries begins with our ability to represent space three-dimensionally. This historical progress began in the early 15th century.

Scales of the Universe: Small, Large, and Complex

It is difficult for us to fathom the scale of the universe. The differences between the smallest structures and the largest are so enormous that linear scales are useless. We need exponential scales, which make the numbers appear to be easy, even when the geometry is simply incomprehensible. A simple example can demonstrate these size differences – there are more atoms in a glass of water than there are glasses of water in all the oceans combined. (If you don’t believe it, here is the math.)

On an exponential scale in meters, humans are located at the midpoint between the nanometer scale (1×10−9 m) (a strand of DNA is 3 nanometers thick) and the scale of stars ( the sun is 1.4 ×109 m in diameter.) Reaching “down”, what we try to do in nanotechnology, is just as difficult as reaching “up,” exploring the solar system with our probes. But, the journey is only beginning.
