Right Brain vs Left Brain

The human brain controls the central nervous system (CNS), by way of the cranial nerves and spinal cord, the peripheral nervous system (PNS) and regulates virtually all human activity.Involuntary, or "lower," actions, such as heart rate, respiration, and digestion, are unconsciously governed by the brain,specifically through the autonomic nervous system. Complex, or "higher," mental activity, such as thought, reason, and abstraction, is consciously controlled. The human brain...

3 Weird Things About the Moon

1. It's blackWell, it's really more of a dark gray. The moon appears white because we have no point of comparison in the night sky. It's an optical illusion. If there were a truly white object next to it, the moon would look quite dingy. 2. It has dust stormsAstronauts report that plumes of particles rise off the lunar surface at dusk and dawn-even though there's no wind. How? One theory is that solar radiation creates an electrostatic charge that lofts the dust into space. &...

Rainbow

A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicoloured arc, with red on the outer part of the arch and violet on the inner section of the arch.A rainbow spans a continuous spectrum of colours; the discrete "bands" are an artefact of human colour vision. The most commonly cited and remembered sequence, in English, is...

The Beauty Of Lightning Storms

A thunderstorm, also known as an electrical storm, a lightning storm, or a storm is a form of weather characterized by the presence of lightning and its effect: thunder. It is usually accompanied by heavy rain and sometimes snow, hail, or no precipitation at all. Thunderstorms may line up in a series, and strong or severe thunderstorms may rotate.

Spectacular Clouds

A cloud is a visible mass of droplets or frozen crystals floating in the atmosphere above the surface of the Earth or another planetary body. A cloud is also a visible mass attracted by gravity, such as masses of material in space called interstellar clouds and nebulae. Clouds are studied in the nephology or cloud physics branch of meteorology. On Earth the condensing substance is typically water vapor, which forms small droplets or ice crystals, typically 0.01 mm in diameter...

1.The Halo Effect: When Your Own Mind is a Mystery The ‘halo effect' is a classic finding in social psychology. It is the idea that global evaluations about a person (e.g. she is likeable) bleed over into judgements about their specific traits (e.g. she is intelligent). Hollywood stars demonstrate the halo effect perfectly. Because they are often attractive and likeable we naturally assume they are also intelligent, friendly, display good judgement and so on. That is, u...

Most Bizzare Experiments Of All Time

The Ape and the Child History contains numerous accounts of children raised by animals. The children in such cases often continue to act more animal than human, even when returned to human society. The psychologist Winthrop Kellogg wondered what would happen if the situation were reversed. What if an animal were raised by humans - as a human. Would it eventually act like a human?

The Mad Scientist Bringing Back the Dead

There are things you should know about, just because they're weird. Did you know that people with diabetes exhale rocket fuel? It's true, but it's weird, right? And spontaneous combustion. That's true, too, apparently, albeit in a bigfoot sort of way. People just explode. Mark Roth keeps a file on them, because, well, for one thing, he's interested in the genetics of spontaneous combustion, and, for another, he's interested in what keeps people from exploding, like, all the t...
