With the prices of gasoline on the rise, and the amount of fossil fuels consumed by the United States, coupled with the effect green house gases are having on our environment, it comes as no surprise that alternative fuels in the automotive industry are being researched. We hear politicians talk about our fuel alternatives and mention electricity as a real possibility for the automotive industry. We hear things like senator McCain offering enormous amounts of incentive monies to help d... more...

The scientific world is never short on impressing us on their wonderful experiments and tricks on finding new information about our human race. One of the things that people with fish tanks will know and use are dissolved oxygen analysers. These measure the amount of dissolved oxygen in liquid and are typically measured in PPM (parts per million). Dissolved oxygen is a process that can happen in fish tanks, which very often can be as a result of algae formation. A dissolved oxygen analyse... more...

A telescope for sale today, is pretty much the same as the ones sold a hundred years ago. Though there are marked differences, the technology pretty much stayed the same. However, in the last few years, computerized GoTo telescopes have become very popular over conventional reflector telescopes. Discover more in this article. Reflector telescopes also known as a Newtonian reflector after Isaac Newton who invented it, is a telescope that operates with a mirror at one end of the telescope, ... more...

How smart where these "cavemen" really? The stereotypes that surround ancient humans were that they were not intellectually developed people, hunting animals using crude means and living life wearing leaves. However, the research shows that not all cavemen were primitive. Man has evolved a long way since he parted company from his jungle cousins, the apes. Apes share ancestors with humans, and like us are also considered primates. Some primates learned to walk on two legs, ... more...

The Hubble Space Telescope is a telescope in orbit around the Earth. It was launched into space on April 25, 1990, and is basically a giant observatory on board a space station. Its position outside the Earth's atmosphere provides a significant advantage over ground based telescopes as the images are not blurred by the atmosphere, there is no background light scattered from the atmosphere, and it can observe ultra-violet light that is absorbed by the ozone layer. Since launched int... more...

We live in an interesting time in that we have escalated our fossil fuel consumption to astronomical proportions while at the same time, have been informed on the condition of our world and the,Global Warming, that is occurring. It is rather odd that we are only given very few alternatives to our $700 billion dollar foreign oil addiction. Wind, Solar, Nuclear. What about Hydrogen? Being the most abundant element on Earth. Completely renewable, and clean. Leave it to a rich oil billionair... more...

When a person mentions the word titration, a lot of blank faces will stare back at them, because many (unless you are scientist) do not know what this means! However, even scientists may struggle in explaining what titration maybe, because this is a term that is more commonly used in chemistry laboratories and medical centres. These have their important purposes for measuring dosages for medication and for essential chemical analysis. The process of titration consists of using the reagent... more...

Mars is the fourth planet from the Sun and is named after the Roman God of war. The planet is a distinctive shade of red and is the last of the rocky terrestrial planets. Mars is substantially smaller than Earth and Venus but larger than Mercury. The planet has been the subject of intense speculation about the existence of extra terrestrial life with evidence of water on the surface at the polar ice caps. While recent robotic explorations have shown that the presence of life is unlikely it has s... more...

Earth is unique among all known planets, ones native to our Solar System or otherwise. It is the only planet that has liquid water on the surface and is also the only world containing life. Earth is the third planet out from the Sun and is the densest and largest of the four rocky terrestrial planets. Formed at the same time as the rest of the Solar System the Earth would accrue enough mass to maintain an atmosphere, composed chiefly of nitrogen and carbon dioxide. It is believed that the... more...

The standard basic tools in a laboratory are usually test tubes, beakers, pipettes, Bunsen burners, Petri-dishes, clamps, callipers, thermometers and microscopes. These are a laboratory must-have, regardless of how big the lab maybe. In schools science teachers teach the students to use each instrument effectively for clear-cut and precise experimentation. Without these instruments it is near impossible to find accurate readings for any tests that are being conducted. One of the smallest ... more...

Named after the Roman Goddess of love, the planet Venus is the second furthest from the Sun. It has been referred to as Earth's twin planet due to its remarkably similar size. Venus is also a rocky planet with a gaseous atmosphere, however it differs from Earth in a number of crucial ways. Venus is the closest planet to Earth and the brightest object in the night sky, with the exception of the moon, and has been referred to as both the Morning and Evening Star due to its luminosity. ... more...

The power of computers is advancing at a rapid pace. Eventually, will we have the power to begin computer simulations of whole human populations? What would this mean economically if we were able to run these types of simulations? Could simulations of economic and political policies first be run on a computer before being enacted in the real world? Would this result in an optimization of economic activity and an ever greater increase in gdp per capita? How does one successfully model human behav... more...

Researchers have recently constructed a new computer model of the cortex of the human brain. This model is similar in principle to the more well known Blue Brain computer model, but it simulates a much larger area of the brain. It actually less detailed at the neuron level when compared to Blue Brain. The Blue Brain project has already simulated a section of the rat's brain that is named the neocortex. The Blue Brain computer simulation has successfully modeled approximately 10,000 neu... more...
