The Asimov's wife say that...: 90% of human being uses your right hand to manipulate the things. Why? The Asimov's wife say that babies are quieter when they are near of the mother's heart, because they can hear it. The mother, therefore, hold your babies with left hand and use the right hand to make other things (the human heart is slightly at left side).

We think that now, in the last decade for instance, we have reached to go over a huge distance in technology, and this is certain but, for instance, the first particle accelerator was constructed in 1928 and the first cycloton in 1931, not ten or twenty years ago...

The long life in human beings can add new problems. If we want to save us from an undesirable rise in population we would have to control the number of births and made them down. Then, we'll have an old population and the matter we'll be that if society became pour in young people, the society will be slowly in changes, in new ideas in cultural renewals,... and, then, it would tend to own decline and death. Our particular longevity is a good thing for our but is the worst thing that could happen at the global of human beings.

Where did the life begin in our planet? Scientist believe that to the ocean surface. That's the classical view, but there're some scientists that believe is possible that life in Earth could have formed on the ocean bottom, where bacteries adapted have been found. These bacteries had been formed in conditions that they had been protected from UV, from disturbances of volcanic heat and meteoric bombardment that the early days were much more common.

Did you know that the bones of the birds are hollow...? In fact, Asimov wanted explain us here about a fossil that was considered the first bird but it had features from lizards with the excepcion of feathers: It had feathers. The feathers are, today, an exclusive from birds and, therefore, this fossil is considered a bird but only it had this feature. This fossil is the archaeopteryx, a perfect exemple of a reptil in the process of evolving into a bird (magic process, I think; or... "the determinism of the chance", I say it)

We think that the biggest animals and vegetals have existed at the pass and this is usually certain, but the biggest of all animals had existed is living at the present: the blue whale.

Oxigen in water is more abundant in cool and icy water than warmer. At oceans, the life is easier in polar seas than tropical seas.

Human beings could convert the sunlights in electrecity IN THE SPACE and convert this electrecity to microwawes that we would beam down to a receiving station on Earth that could again convert the microwawes to electrecity for distribution. The solar cells in the space that would do this would have an area equal to that Manhattan Island. What's more, we would need about sixty such devices placed in orbit above equator.
The solar cells in space are six times eficience than on Earth.

When in 1846, the astronomers indicated where the eight planet would have to be, in only half-hour of searching Neptune was discovered.

Andromeda and Milky Way galaxies are closed enough to collide in the futur... And they'll collide!! ...sure! What will happens, then?

Did you know that Voyager 2 will travel for more than a million years before a minimal possibility that other inteligents creatures could find it there is...? We have delivered a message at space; it's possible isn't read by no one, but we'll have left a trace of us in the universes when we have disappeared, if we do it.
The books,... they're always teaching us something new!
