    VACUUM TUBE
    October 20, 1906 - American Institute, U.S.A.

    Dr. Lee DeForest (26 Aug 1873 - 30 Jun 1961), one of the “fathers of radio,'' announced his three-element electrical vacuum tube (now known as a triode) to a meeting of the American Institute of Electrical Engineers He had discovered that when a mesh, or grid, of wire was placed between the filament and collector “plate” in a diode tube (first made by J. Ambrose Fleming, 1904), a large voltage-amplifying effect could be produced. DeForest patented this vacuum tube on 15 Jan 1907. The ability of this tube to amplifiy weak signals was an invention as great as radio itself, because it made long-distance communication possible.

    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying.

An Introduction To Karate Training:

Most likely one of the most well known forms of martial arts around the world is Karate. This is most likely because it features all the elements that you will want in a martial art. Karate can certainly help you to be physically and mentally fit, it may be a competitive sport and it can provide skills for self defense.

The word Karate means "empty hand" in Japanese and this system of strikes, kicks and punches is something that just about any adult or youngster can be taught. This is certainly one of the few martial arts where the whole family can participate. If you are new to this and you're wanting to know what you might expect from a Karate class we're going to take a look at some of the basics in this article.

You'll find that there are several types of Karate with different focus on either strength or speed. A lot of Karate lessons begin with warm ups that include stretches and exercises. All these warm ups help build our flexibility so that we can do our kicks and moves without harming ourselves. It is very important to be well conditioned and well developed so these warm ups are essential. Without a doubt, you'll feel much better and stronger after only a few Karate lessons.

After your warm up, you will begin to perform specific Karate moves. Your stance and feet placement is essential in Karate and to make certain that every movement is correct, you'll be doing a particular move many times over until it's done correctly. You'll usually be shown the move first by your teacher and then you get the chance to do this yourself. The continual repetition can certainly help make the moves you learn become part of your instinct so that when you do a certain strike, it all comes to you easily.

One other aspect of Karate is what is called "kata" which is basically doing a sequence of different moves in a combination of strikes, kicks and blocks. It is common to see "kata" being executed at a Karate convention and it is taught to students as they move up the grading system. At some point during your lesson there will also be a chance for some live training with individuals of a similar experience to you. This is to help you obtain some real experience with an individual and help you ascertain where you stand in your learnings. While sparring sounds dangerous, it is really a light exercise to help you check if you are correctly positioned and angled when you do different moves and strikes.

As you get to the end of lesson, you're going to be winding down by doing various stretches. It is actually fair to say that every club will have their own way of doing things but in most cases this gives you an idea of what to expect if you join a Karate club.
