Under modern scanners brain tissue loss may be a loss of synapses and mylar that make distractions more profound as we age. Noise in the brain can become an issue and the weakening as we age, as well as the fear of falling. Again, this starts with the brains. As we learn to rely on weakening vision, and are going through a crowd, we get bumped

The first inhabitants of the world were compelled to accommodate their acts to the daily and annual alternations of light and darkness and of heat and cold. In history there are only a few distinguished men who made such a big contribution to astronomy, one of them was Galileo Galilei and his work with the telescope. When we look at today's tele

In agriculture and science, electrical conductivity (EC) is an excellent way to measure water, soils and fertilisers using a handheld meter or desktop device. Fundamentally, it is possible for them to do this by measuring the dissolved salts in solutions and hence the salt content of soil or water; more salt will mean a higher conductivity of the s

Almost all of us are acquainted with lasers, as we have used or seen lasers in action at some point of our lives. Lasers are used in a variety of places, like for pointers for a presentation in a corporate boardroom classroom or as a cat toy. A closer example at home is the usage of lasers in the CD players, where a laser is used to read the in

Whilst the question could be deemed to be a little ambiguous, you may get a tick or a cross depending on the questioners point of view. It was Humphrey Davy, the English chemist who first attached wires to a battery and passed an ele

You are reading this article because you are interested in how photovoltaic solar energy works right? That would also mean you are interested in a clean,cheap reliable source of energy that is also renewable? Once the mystique is removed from discovering the process of how does photovoltaic solar energy work people will began to see the usefulness

If your inclination is towards a scientific career, naturally the place to begin building your future is in the place where you are right now. If you are in junior or senior high school, for instance, you can take a second look at the courses you plan to schedule. If you have not included all the mathematics and science you can fit in, perhaps t

After seeing the starry pictures from NASA, you may be wondering how to buy a telescope, and explore the universe for yourself. There are many department stores selling telescopes, however, to buy a telescope which will help you with looking at objects clearly in the night sky, you will need to know some key points. Most people, who think about

If you are a serious astronomy nut, you know the single most challenging aspect of star gazing is light pollution. With most of the population living in and near major cities, finding a nice piece of sky with little light pollution is getting more and more challenging. However, there are things the star-gazer can do to limit the effects of too much

Often we will see and hear about telescopes, and have a preconceived notion that a telescope is essential to be able to do backyard astronomy, however this is not the case. Nor is it essential to spend hundreds if not thousands of dollars to get started in backyard astronomy as a hobby. It is true that to get the best views of the Moon, Jupiter,

Waste incineration is probably one of the most effective ways of getting rid of factory and industrial products. The problems of trying to expel wastage are that there is not enough space on the earths ground to keep them. In addition, they cause issues to the environment as well effect the top soil of the earth's ground. Hot gas filters are used f

Some years ago I read of the well documented archaeological find of a hammer head and part of a shaft found embedded in Cretaceous sandstone near London Texas. It was found in stone not clay or soil. The sandstone in which the hammer was found contained Lower Cretaceous fossils of the kind that would be dated by old earth evolutionists at rough

We all know that drinking and driving don't mix. At least drinking alcohol and driving doesn't mix well. However, it may be a good idea to turn your car into an Alcoholic and let it drink as much 200 proof alcohol as it wants. Now I'm not talking about the Whiskey some people drink, although it has the same alcohol your car will drink once i

I am fortunate to be living in a region of Australia with one of the richest Aboriginal cultures and a living history. North East Arnhem land in the Northern Territory is located at the confluence of the Arafura Sea and the Gulf of Carpenteria. As an Avid Astronomer I am always on the lookout for an opportunity to share the night sky with others. T

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.
