136: Iron and Carbon Make Wonderful Things When Allied With An Alloy
We've grown up hearing about stainless steel our whole lives. But how many people actually know what it really is? Let's take a look at the process of making steel stainless and some of its general applications.
English metallurgist Harry Brearley invented stainless steel in 1912 while he was researching alloys to protect cannons from erosion.
137: MycologyThe Study Of Mold And Other Fungi
Mycology is the study of fungi and their biochemical and genetic properties, and their applications to human life such as medicines, food, and the dangers that they can present such as infections. This includes not only mushrooms, but also molds and bacteria. Phytopathology, which is the study of plant diseases, came about from mycology and these
138: The Magnificent Planet We Call Home
Our home planet Earth is the third planet out from the Sun and is the largest and densest of the four inner planets. Earth is also the first planet out from the Sun that has a Moon and is the only planet in our Solar System where liquid waters exists in large quantities on the surface. It is generally agreed that the existence of liquid water is th
139: The Science of Early Learning
Your baby is born with most of the brain cells she will ever have, but during her first 12 months in the world, her brain will become increasingly complex. By the time she reaches the age of two, her brain will already be 75 percent of its adult weight. By the age of three, it will have reached 90 percent of its adult weight.
Almost 50 percent o
140: Why Now Is Important For Astronomy
We are at a critical juncture in solar system exploration. On the drawing boards are dozens of promising ideas, many which could be realized in the coming decades. There is plenty of incentive for human expansion into the solar system, yet there is no long-term commitment and no consensus on how or when it will occur.
This past May, at the fifti
141: A Fossils Formidable Years
Ever wonder exactly what a fossil is or where they came from? Fossils are actually the remains of plants or animals that lived millions of years ago. While that is what they are, fossils still to this day serve a very important purpose. They are able to provide some very important information about what life was like millions of years ago. A You
142: Alternative Energy Systems May Create Low Cost Power
Each time the price of electricity increases, people begin seriously searching for alternative energy systems to reduce their electrical consumption. Many others however, are searching for way to reduce their reliance on energy produced by fossil fuels or nuclear power, looking at the natural and renewable resources such as the sun and the wind. Wh
143: Ancient Vedic Math And Mental Math Controversies
Vedic Mathematics came out of the closet, so to say, in the middle twentieth century, thanks to the efforts of Sri Jagatguru Swami Sri Bharati Krsna Tirthaji Maharaja. His contribution to the understanding of Vedic mathematics as it stands today is phenomenal. In fact, the 16 Sutra he has culled from the enormous depth of the Vedas is unimaginable.
144: Are GMO Food and Organic Foods an Either / or Proposition?
Are GMO Food and Organic Foods an Either / or Proposition?
By Ranjana Smetacek
Consumers have many choices about the foods they eat, and those choices are impacted by numerous factors including price, quality, taste, convenience, health benefits and process attributes – just to name a few. To make an informed decision today, consumers need a good
145: Cold Case Phoenix And The Outlook For Life On Mars
The Phoenix Mars Polar Lander is slated to land on Mars' north pole on May 25th - very soon now! Phoenix is intended to look for signs of microbial life, and there's a case that evidence may be found on Mars.
The first piece of evidence is purported microfossils found in an Antarctic meteorite in 1997 - this Shergottic meteorite ALH84001, estim
146: Getting The Best Mass Air Flow Meter For Precision
A mass air flow meter is usually used for measuring the flow rate or quantity of a moving gas. This mass air meter, which is also sometimes known as mass flow sensor, responds to the amount of the gas flowing through a specified chamber. Usually this meter or sensor is not influenced by the density of the gas, but merely the quantity only.

147: Harnessing Wind Energy
While some of these places are just starting up their wind farms and wind energy harnessing technology, other countries have a fully formed plan to use this renewable resource to energy their homes and cities. Much of Europe has begun to build and use wind farms, which are groupings of wind turbines that harness the energy of the wind in order to c
148: How Far Can You See With A Telescope
You have seen the pictures from NASA. Those pictures from the Hubble Space Telescope, and now you want to see to the ends of the universe. However, before you plunge into buying a telescope to see the heavens there is something to consider.
You go into a toy store or similar place, and find in the science section a low cost telescope. Now soon a
149: How To Choose A Pair Of Binoculars For Astronomy
Many people believe that you need a telescope to be able to view space. However, this is not the case, and sometimes could get you out of astronomy sooner, than if you had started with a good pair of binoculars for astronomy.
Telescopes are great, however, most of the telescopes available are those found in toy stores. These telescopes look enti
150: Increasing Your Fuel Economy / Mpg
Out of engine efficiency come both power and economy, so if an engine is more powerful for its capacity this allows it to run at a lower RPM to move the vehicle. Because we create more torque from the engine, you can move into a higher gear at an earlier point during acceleration and then maintain that higher gear for a longer time.
