They observed that every rock formation, no matter how ancient, appeared to be formed from still older rocks.Comparing these rocks with the products of present erosion, sedimentation, and earth movements, these earliest geologists soon concluded that the time required to form and sculpt the present Earth was immeasurably longer than had previously been thought.

You can break it, and you can glue it back together, but it's not going to be as strong as it was unless the person is really committed to not bringing home nurses!

Drama and reality combine in a fictitious 24 hours in the life of musician and international cultural icon Nick Cave. The never-ending drip feed of eroticism" Nick Cave I'm not sure either what that quote means, but what you may get is a sense of writer/musician Nick Cave's poetic inclinations and the sensuality of his life, encapsulated in a fictional day, his 20,000 day on earth to be specific.

James Hutton, a physician-farmer and one of the founders of the science of geology, wrote in 1788, “The result, therefore, of our present inquiry is, that we find no vestige of a beginning, — no prospect of an end.” Although this may now sound like an overstatement, it nicely expresses the tremendous intellectual leap required when geologic time was finally and forever severed from the artificial limits imposed by the length of the human lifetime.

By the mid- to late 1800s, geologists, physicists, and chemists were searching for ways to quantify the age of the Earth.

The discovery of radioactivity in 1896 by Henri Becquerel, the isolation of radium by Marie Curie shortly thereafter, the discovery of the radioactive decay laws in 1902 by Ernest Rutherford and Frederick Soddy, the discovery of isotopes in 1910 by Soddy, and the development of the quantitative mass spectrograph in 1914 by J. Thomson all formed the foundation of modern isotopic dating methods.

But it was not until the late 1950s that all the pieces were in place; by then the phenomenon of radioactivity was understood, most of the naturally occurring isotopes had been identified and their abundance determined, instrumentation of the necessary sensitivity had been developed, isotopic tracers were available in the required quantities and purity, and the half-lives of the long-lived radioactive isotopes were reasonably well known.

Janet is an over-weight girl who has a knack for making the other children in school laugh..making fun of her own weight.

In seeing the other kids reaction, she feels that she might ...

Interspersed are performances with The Bad Seeds, from his almost Leonard Cohen-like poetic music to his Jagger-like rocking in Sydney (he's an Aussie), where the capacity crowd is fully under his spell.

As he speaks through the music about its transforming power, he also shows us his struggle to bring poems and lyrics together. musician: "Musicians are at the bottom of the creative pyramid and authors are at the top, and many people think it's unacceptable for someone to attempt to jump from the bottom to the top of the pyramid."Along the way we see him and his sons eat pizza and watch Scarface.

Radiometric dating is based on the decay of long-lived radioactive isotopes that occur naturally in rocks and minerals.
