Perhaps the most impressive illustration of all is to suppose that you could label the molecules in a tumbler of water. ... threw it anywhere you please on the earth, and went away from the earth for a few million years while all the water on the earth, the oceans, rivers, lakes and clouds had had time to mix up perfectly. Now supposing that perfect mixing had taken place, you come back to earth and draw a similar tumbler of water from the nearest tap, how many of those marked molecules would you expect to find in it? Well, the answer is 2000. There are 2000 times more molecules in a tumbler of water than there are tumblers of water in the whole earth.

What actually happens when you die is that your brain stops working and your body rots, like Rabbit did when he died and we buried him in the earth at the bottom of the garden. And all his molecules were broken down into other molecules and they went into the earth and were eaten by worms and went into the plants and if we go dig in the same place in 10 years there will be nothing except his skeleton left. And in 1,000 years even his skeleton will be gone. But that is all right because he is part of the flowers and the apple tree and the hawthorn bush now.When people die they are sometimes put into coffins which means that they don't mix with the earth for a very long time until the wood of the coffin rots.But Mother was cremated. This means that she was put into a coffin and burnt and ground up and turned into ash and smoke. I do not know what happens to the ash and I couldn't ask at the crematorium because I didn't go to the funeral. But the smoke goes out of the chimney and into the air and sometimes I look up into the sky and I think that there are molecules of Mother up there, or in clouds over Africa or the Antartic, or coming down as rain in rainforests in Brazil, or in snow somewhere.

Leonardo believed his research had thepotential to convert millions to a more spiritual life. Last year he categorically proved the existence ofan energy force that unites us all. He actually demonstrated that we are all physically connected… that the molecules in your body are intertwined with the molecules in mine… that there is a single force moving within all of us.

And the power of God shall unite us all. “Mr. Vetra actually found a wayto demonstrate that particles are connected?”“Conclusive evidence. A recent Scientific American article hailed New Physics as a surer path to Godthan religion itself.

forming the "hydrogen bond"... is dynamic, with the exchange occurring in a few billionths of a billionth of a second. Since water molecules can "lose" two hydrogen atoms and "win" two by way of their oxygen atom, they are on average regrouped in fours, and the network of water, whether in our glass or in our cells is tetrahedral. All the same, this arrangement is not perfect in liquid water (otherwise the water would be a solid crystal), and locally there are many defects in the network. Although the motif of four water molecules is the most common in "linear" hydrogen bonds, the water molecule sometimes has a "forked tongue" with bifurcated liaisons, which creates arrangements of three or five, or even two or six molecules. This variability prevents water from being structured over a great distance and enables it to remain in a liquid state at the ambient temperature.

Recall the metaphor I used in chapter 4 relating the random movements of molecules in a gas to the random movements of evolutionary change. Molecules in a gas move randomly with no apparent sense of direction. Despite this, virtually every molecule in a gas in a beaker, given sufficient time, will leave the beaker. I noted that this provides a perspective on an important question concerning the evolution of intelligence. Like molecules in a gas, evolutionary changes also move every which way with no apparent direction. Yet we nonetheless see a movement toward greater complexity and greater intelligence, indeed to evolution’s supreme achievement of evolving a neocortex capable of hierarchical thinking. So we are able to gain an insightinto how an apparently purposeless and directionless process can achieve an apparently purposeful result in one field (biological evolution) by looking at another field (thermodynamics).

The same few dozen organic molecules are used over and over again in biology for the widest variety of functions.

Life is not found in atoms or molecules or genes as such, but in organization; not in symbiosis but in synthesis.

The brain is not nourished on beans and truffles but rather the food manages to reconstitute the molecules of the brain once it has been turned into homogeneous and assimilable substances, which potentially have the "same nature", as the molecules of the brain
