Mahatma Gandhi escribió: Las raíces de la violencia: la riqueza sin trabajar, el placer sin conciencia, el conocimiento sin carácter, el comercio sin moralidad, la ciencia sin humanidad, el culto sin...
Let us discuss these problems in some detail. One problem is to amass enough energy to rip the fabric of space and time. The simplest way to do this is to compress an object until it becomes smaller t...
Kaluza also gave an answer as to where the fifth dimension was. Since we see no evidence of a fifth dimension, it must have curled up so small that it cannot be observed. (Imagine taking a two-dimensi...
In other words, the process of observation determines the final state of the electron.
In other words, our destiny is to become the gods that we once feared and worshipped. Science will give us the means by which we can shape the universe in our image. The question is whether we will ha...
In fact, there is one theory that states that dark matter, an invisible form of matter that surrounds the galaxy, might be ordinary matter floating in a parallel universe. As in H.G. Wells's novel The...
Hay un viejo dicho que reza: «Ten cuidado con lo que deseas, porque igual se hace realidad». El Santo Grial de la nanotecnología es crear el ensamblador molecular, o replicante, pero, una vez que esté...
Galileo believed that science and religion could coexist. He wrote that the purpose of science is to determine how the heavens go, while the purpose of religion is to determine how to go to heaven. In...
Cosmology is the study of the universe as a whole, including its birth and perhaps its ultimate fate.
By 2020, the flat panel displays will likely come in a variety of forms. They will be miniaturized to work as wristwatch screens and may be added to eyeglasses or key chains. Eventually, they will bec...
As Sir William Osler once said, The philosophies of one age have become the absurdities of the next, and the foolishness of yesterday has become the wisdom of tomorrow.
When we force a smile, we activate facial muscles with our prefrontal cortex. But when we smile because we are in a good mood, our nerves are controlled by our limbic system, which activates a slightl...
Will we no longer be the most intelligent being on earth,
These parallel universes are not ghost worlds with an ephemeral existence; within each universe, we have the appearance of solid objects and concrete events as real and as objective as any.
The problem is that while twenty-first-century physics fell accidentally into the twentieth century, twenty-first-century mathematics hasn't been invented yet. It seems that we may have to wait for tw...
The brain, like it or not, is a machine. Scientists have come to that conclusion, not because they are mechanistic killjoys, but because they have amassed evidence that every aspect of consciousness c...
The 3-D printers of the future might be able to re-create the delicate tissues that constitute functioning organs or the machine parts necessary to make a self-replicating robot.
Of course, the set of logically consistent mathematical structures is many times larger than the set of physical principles. Therefore, some mathematical structures, such as number theory (which some...
Looking back at those dark days, I am sometimes reminded of what happened to the great Chinese imperial fleet in the fifteenth century. Back then, the Chinese were the undisputed leaders in science an...
Last is D, the number of spatial dimensions. Due to interest in M-theory, physicists have returned to the question of whether life is possible in higher or lower dimensions.
