The brightest area on Ceres, located in the mysterious Occator Crater, has the highest concentration of carbonate minerals ever seen outside Earth, according to a new study from scientists on NASA’s Dawn mission. “This is the first time we see this kind of material elsewhere in the Solar System in such a large amount,”...
Apostrophes often cause writers a great deal of anxiety. Indeed, some writers avoid their use altogether for fear of misusing apostrophes. Spend just a little time on this section, read the explanations, complete the exercises and you will become an expert on the use of apostrophes. Apostrophes are used for two main re...
In this Section: In this section, we learn how to perform operations with polynomial functions. We begin by defining a polynomial function. We then learn how to evaluate a given function for a specific input. For example, if we see f(x) = 5x + 3, we could ask what is the function’s value when x is 5 with: f(5) = 5(5) +...

Thomas Jefferson, who was personally requested by John Adams to draw up a draft of the Declaration of Independence, initially blamed the king of England for the enslavement of African people. The entry reads, in part: “He has waged cruel war against human nature itself, violating its most sacred rights of life and libe...
The first speculations about the possibility of the Sun being the center of the cosmos and the Earth being one of the planets going around it go back to the third century BCE. In his Sand-Reckoner, Archimedes (d. 212 BCE), discusses how to express very large numbers. As an example he chooses the question as to how many...

As we saw in a previous post, visible light is simply one portion of the electromagnetic spectrum i.e. visible light consists of electromagnetic waves of a certain frequency travelling at a speed of 3 x 108 m/s (recall also that light can exhibit properties of both waves and particles, a property referred to as quantum...
The Toltec civilization existed in central Mexico for a relatively short time period before the Aztec civilization, from approximately 900 to 1200 AD. There is not a lot of available history of the Toltecs due to a lack of written documentation and archeological findings, but it seems that this people had ancient assoc...
When people think tornado, the first thing that comes to mind is the strong or violent tornado of the Great Plains, generated by supercell thunderstorms. But nature manufactures tornadoes in many ways, and another relatively ubiquitous type are “squall line tornadoes,” generated along the front edge of a bowing or arc-...
for division, they must also know how to subtract.

The origin and nature of Mars are mysterious. The planet has geologically distinct hemispheres with smooth lowlands in the north and cratered, high-elevation terrain in the south. The red planet also has two small oddly-shaped oblong moons and a composition that sets it apart from that of the Earth. New research by CU ...
Simple Steps to Solve Linear Equations Three Main Rules A linear equation is any two expressions (like “3x+2” or “54”) set equal to each other, assuming that none of the variables in the equation are raised to a power higher than 1. For example, “4x+8=29” is a linear equation, but “5x^4=100” is not a linear equation, b...
Pinpointing the start of the Holocaust is open to debate. I think a good place to begin would be with the passage of the Nuremberg Laws in September 1935. These laws denied the Jewish people the rights of citizenship. Jews couldn't marry Germans. By the end of 1935, Jews could not vote or hold public office. By 1936, s...
The crust at the bottom of the oceans is dense, heavy, and tough. Even so, it disappears in a hurry -- it’s pulled into the layer below the crust, where it melts and vanishes. Ocean crust forms along mid-ocean ridges, where molten rock pushes up from the mantle, the layer below the crust. It’s denser than the rock that...
We are starting to get deeper into our understanding of China. Last week we completed maps and looked at the early dynasty, the Shang. This dynasty was considered legendary until around the early 1900’s when archeologists finally found artifacts to support the legends. So, for an activity, we examined pictures of artif...
Trojan asteroids are objects that share a planet's orbit around the Sun but reside in what are basically gravitational dead zones.
