The Pentagon has been looking into the possibility of developing smart dust, dust-sized particles that have tiny sensors inside that can be sprayed over a battlefield to give commanders real-time info...
Terraforming Mars is a primary goal for the twenty-second century. But scientists are looking beyond Mars as well. The most exciting prospects may be the moons of the gas giants, including Europa, a m...
Tachyons at first seem to violate causality, but physicists believe that their true purpose was to set off the big bang and hence they are not observable anymore.
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...
Scientists have, in fact, assembled long lists of scores of such happy cosmic accidents. When faced with this imposing list, it’s shocking to find how many of the familiar constants of the universe li...
Recently a promising chemical called resveratrol has been isolated. Resveratrol, found in red wine, helps to activate the sirtuin molecule, which has been shown to slow down the oxidation process, a p...
Physicists then tried to calculate the amount of negative matter or energy necessary to propel a starship. The latest results indicate that the amount required is equivalent to the mass of the planet...
Number 1: I calls ’em like I see ’em. Number 2: I calls ’em the way they are. Number 3: They ain’t nothing till I calls
Newton had invented the calculus, which was expressed in the language of differential equations, which describe how objects smoothly undergo infinitesimal changes in space and time. The motion of ocea...
Nature is like a work by Bach or Beethoven, often starting with a central theme and making countless variations on it that are scattered throughout the symphony. By this criterion, it appears that str...
Los humanos somos los únicos en todo el reino animal capaces de comprender el concepto de mañana
La única predicción importante que no se ha cumplido es la clonación humana.
It seems that the one characteristic most closely correlated with success in life, which has persisted over the decades, is the ability to delay gratification.
It is estimated that, if the ice caps of Mars were completely melted, there would be enough liquid water to fill a planetary ocean fifteen to thirty feet deep.
Ironically, the serious study of the impossible has frequently opened up rich and entirely unexpected domains of science. For example, over the centuries the frustrating and futile search for a perpet...
Indeed, Isaac Newton himself, who introduced the concept of immutable laws which guided the planets and stars without divine intervention, believed that the elegance of these laws pointed to the exist...
In other words, symmetry is the preservation of the shape of an object even after we deform or rotate it. Several kinds of symmetries occur repeatedly in nature. The first is the symmetry of rotations...
Hinton spent most of his adult years trying to visualize higher spatial dimensions. He had no interest in finding a physical interpretation for the fourth dimension. Einstein saw, however, that the fo...
Even if the electrons are separated by many light-years, you instantly know the spin of the second electron as soon as you measure the spin of the first electron. In fact, you know this faster than th...
Entire cities could sprout instantly in the desert, with skyscrapers made entirely of force fields.
