La forma humanoide con simetría bilateral, la misma forma que utiliza Hollywood para representar a los alienígenas en el espacio, no tiene por qué aplicarse necesariamente a toda la vida inteligente.
Are skilled in the techniques necessary to neutralize any rogue robot.
You might one day be able to send the experience of dancing the tango, bungee jumping, or skydiving to the people on your e-mail list. Not just physical activity, but emotions and feelings as well mig...
Why go to the stars? Because we are the descendants of those primates who chose to look over the next hill. Because we won’t survive here indefinitely. Because the stars are there, beckoning with fres...
When the Ramanujan function is generalized, the number 24 is replaced by the number 8. Thus the critical number for the superstring is 8 + 2, or 10. This is the origin of the tenth dimension. The stri...
We have learned more about the brain in the last fifteen years than in all prior human history, and the mind, once considered out of reach, is finally assuming center stage.
We are now entering a new golden age of neuroscience.
This means that, in some sense, free will is a fake. Decisions are made ahead of time by the brain, without the input of consciousness, and then later the brain tries to cover this up (as it’s wont to...
Third is Omega, the relative density of the universe. If Omega were too small, then the universe would have expanded and cooled too fast.
There is a cosmic entanglement between every atom of our body and atoms that are light-years distant. Since all matter came from a single explosion, the big bang, in some sense the atoms of our body a...
The right hemisphere controls sensory attention and body image; the left hemisphere controls skilled movements and some aspects of language.
The lesson here is that it is very dangerous to bet against the future.
The geometry of a universe is very like the grammatical structure of a sentence. Just as a sentence has no structure and no existence apart from the relationships between the words, space has no exist...
Studies have shown that retaining memories can be improved by getting sufficient sleep between the time of activity and a test. Neuroimaging shows that the areas of the brain that are activated during...
PREFACE Cosmology is the study of the universe as a whole, including its birth and perhaps its ultimate fate. Not surprisingly, it has undergone many transformations in its slow, painful evolution, an...
Nobel laureate Richard Feynman was fond of saying that no one really understands the quantum theory. Ironically, although the quantum theory is the most successful theory ever proposed by the human mi...
Nobel laureate Elizabeth Blackburn is more optimistic and says, Every sign, including genetics, says there's some causality [between telomeres] and the nasty things that happen with aging. She notes t...
Los humanos somos los únicos en todo el reino animal capaces de comprender el concepto de mañana
Indeed, brain scans done by scientists at Washington University in St. Louis indicate that areas used to recall memories are the same as those involved in simulating the future. In particular, the lin...
In other words, positive matter and energy that we see in stars can warp space-time so that it perfectly describes the motion of heavenly bodies. But negative matter and energy warp space-time in biza...
