So someday in the near future hopefully rather than having a foot or a leg amputated we'll just give you an injection of the cells and restore the blood flow. We've also created entire tubes of red blood cells from scratch in the laboratory. So there are a lot of exciting things in the pipeline.

Reality is observer-determined - it's a spatio-temporal process, which fortunately means that things must change.

I think it's science and physics are just starting to learn from all these experiments. These experiments have been carried out hundreds and hundreds of times in all sorts of ways that no physicist really questions the end point. I think that these experiments are very clearly telling us that consciousness is limitless and the ultimate reality.

We don't have time to wait for President Bush to change his mind. How many breakthroughs have been missed as a result of this policy?

For example, if the big bang had been one-part-in-a billion more powerful, it would have rushed out too fast for the galaxies to form and for life to begin.

When you turn from one room to the next, when your animal senses no longer perceive the sounds of the dishwasher, the ticking clock, the smell of a chicken roasting - the kitchen and all its seemingly discrete bits dissolve into nothingness - or into waves of probability.

We have failed to protect science against speculative extensions of nature, continuing to assign physical and mathematical properties to hypothetical entities beyond what is observable in nature.
