Teens Need Math To Land Dream Jobs

What do doctors, lawyers and architects have in common? For one, they are among teens' hottest career choices. They also require a significant understanding of math at work every day. Despite this, many teens are not motivated to take advanced math classes to help them prepare for success in these future careers. A telephone survey of 1,000 12- to 17-year-olds commissioned by Texas Instruments revealed that four out of five teenagers believe math is important for achieving their goals of being doctors, scientists, executives and lawyers, but only ...

The Origins of Biological and Chemical Warfare

Chemical and biological warfare are not an invention of the 20th century. Solon (638-559 BC) used a strong purgative, the herb hellebore, in the siege of Krissa. During the 6th century BC, the Assyrians poisoned enemy wells with rye ergot. In the Peloponnesian War (431-404 BC), the Spartans flung sulfur and pitch at the Athenians and their allies. In the Middle Ages, besiegers used the bloated and dripping bodies of plague victims as readymade "dirty bombs". In 1346, during its siege of Kaffa (present day Feodosia in Crimea), ...

Wind Farms – Limitations as Energy Platforms

As modern society searches around for alternative energy sources, wind farms are getting mention. There are, however, limitations regarding wind farms as major energy alternatives. Wind Farms – Limitations as Energy Platforms Wind power is an enticing energy platform compared to fossil fuels. The process works by using the inherent energy in wind as a method for producing electricity. The actual methodology is much like hydropower, but with wind used in place of water. Wind turbines catch the wind, which turns their blades. This turning motion cranks a ...

The Compounds Pueraria Mirifica So Special And Different From Other Phytoestrogen Plants

Before we begin, know that our goal is to give you as much useful information as we can fit on our page. The compounds that make Pueraria mirifica so special and different from other phytoestrogen plants are Miroestrol and Deoxymiroestrol. These two compositions posses highest estrogenic activity among the known phytoestrogens, due to structural similarity to estradiol of the main human estrogen in women's body. Pueraria mirifica also contains other chemicals that belong to Isoflavones, e.g. Genistein, Daidzein, Daidzin, Genistin and Coumestrol that are usualy found in soybeans. ...

Characteristics of sound

Sound in brief but remarkeable terms is a vibration, that our ears percieve by the sense of hearing. Most commonly vibrations travel to our ears via the air. The ear then converts these sound waves into nerve impulses that are sent to our brains, where the impulses become sound. To say all that in a more technical language: Sound "is an alternation in pressure, particle displacement, or particle velocity propagated in an elastic material" (Olson 1957). Sound is also a series of mechanical compressions and rarefactions or longitudinal ...

Help Teach Teens: Math Counts Every Day

Many parents may admit math was not their favorite subject in high school. Many may also admit that math now plays an important role in their lives and careers-and will be necessary for their own children's futures. According to the Bureau of Labor Statistics, by 2014, 6.3 million jobs will require science, engineering or technical training-24 percent more than in 2004. These statistics show that today's middle and high school students will need a strong math background to be competitive in the job market. Spending time with teens ...
