The short version of how scientists believe the Earth formed goes like this: Roughly 4.5 billion years ago, the solar system was a spinning disk of gas and dust that looked something like a record, and one groove in that record collapsed into a molten orb that became our planet. About 700 million years later, when Eart...
Ancient Egypt's transition to statehood happened faster than thought A new paper reports that Egypt’s transition from a smattering of villages to one of history’s most enthralling political states took just 600 to 700 years. Sometime in the 4th millennium BC, the pastoralists that had canvased the Sahara desert, packin...

When a set of data follows a normal distribution pattern, the mean and standard deviation can be used to calculate the percentage of data falling inside a given range. The z table makes this possible. Simple Definition of a Z Score Referencing the illustration below, the Z score is simply how many standard deviations o...
Flux is effectively the amount of Field passing through a surface. In other words, it is analogous to a stream of water; if you put a screen in a creek, then water will pass through it. The amount of water moving through it is the flux. Using the water analogy, point charges can be viewed as a source (such as a hose or...
Is There Anybody Home? NASA's Spitzer Space Telescope recently captured these infrared images of six older stars with known planets. The yellow, fuzzy blobs are stars circled by disks of dust, or "debris disks," like the one that surrounds our own Sun. Though astronomers had predicted that stars with planets would harb...
Building functions into microchips mean they run fast and efficiently, despite the fact it reduces the flexibility of what the hardware can do.

Today in History – December 30, 1924 – Edwin Powell Hubble announces his discovery of a galaxy outside the Milky Way. Edwin Hubble was one of the leading astronomers of the twentieth century. His discovery that not only one, but countless galaxies, exist beyond our own Milky Way galaxy forever changed our understanding...
Ohm’s Law tells us that current and voltage are directly proportional: doubling the voltage will also double the current. The power dissipated in a resistor is given by the formula P = V2/R. Since P and R are inversely proportional, multiplying the resistance by four will divide the power by four. The resistance for a ...
NASA is prepared to launch a mission to Jupiter this week that will probe deep into the planet’s clouds to reveal what it is made of.
