Science Quotations

I do not know what I may appear to the world, but to myself I seem to have been only a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

-- Sir Isaac Newton

Radioactive Decay Demonstrations

Looking for some interactive demonstrations for radioactive decay?

Here are some interesting demonstrations to illustrate radioactive decay. The first link allows you to choose the half-life, up to 100s.

The following page contains a link to a fascinating interactive decay facility. You can choose the isotopoe, then watch the decay process for the isotope, with the associated  increase of the resulting stable nuclei. Considers some gamma-emitting radioactive isotopes  cobalt (Co60), iridium (Ir192), cesium (Cs137), ytterbium (Yb169), and thulium (Tm170).
