Death is coming

The closer death creeps up upon me the less I am able to understand the reasons for life or living.

Yes I have experienced a close family member dying and unlike television it takes decades to handle such a thing. To think I am going to put my family through such a thing when I finally leave is more horrific to me than the thought of death itself.

My life was and is still a learning experience but when all said and done what am I to do with all this accumulated learning over my lifetime if I just die. There is no logic or reason to this.

Long ago I became aware that the God story that is sold to the majority is just a nice story to give mankind with a message of a basic layout of how nice life could be if everyone followed these ideas. Not many in life do and if one thinks about it the good and evil structures actually depend on each other. The good that can be experienced in life is only understood as good when there is it's opposite to compare it to. This is not rocket science only common sense in reality. I am not saying we need to experience bad but understanding in it is needed to appreciate the great things many of us can have in our lives. From birth to death there are many ways mankind helps his fellow man. How many ways can you help?

Background Info on Atomic Clocks

By David Artstone

The atomic clock is more than just a cool space age technology, it is actually a vital part of the modern world, ensuring that everything keeps running in a smooth and functional manner.

If regular wall clocks stopped and you needed to reset it, you look at another time telling device to know what time it is. Now, if there was no other clock or watch, how would you know what time it was? This is the question scientists have tried to answer over time because it is possible that at a point in time you may have only one time piece and if that needs to be reset, you do not have any other reference to set your time.

Atomic clocks answer these difficulties. The atomic clock is a highly accurate and independent timepiece. They are so accurate that Global Positioning Systems (GPS) and television broadcasts rely on their horological properties to function. They use oscillations between the nucleus of an atom and the neighboring electrons to work, hence their name.

There are three main types of atomic wall clocks.

Cesium clocks constantly emit cesium atoms to keep time. The mechanism employs magnetic field to separate cesium atoms of differing energy levels. This type is the most complex and accurate of all atomic clocks.

The Hydrogen atomic clocks keep time by housing hydrogen atoms in an enclosure and thus prevent them from escaping readily.

Rubidium clocks apply rubidium gas glass cell to control optical and microwave frequencies to keep time. The Rubidium is the simplest of all atomic clocks.

Atomic clocks are widely used by the military, aerospace industry and satellite companies to keep accurate, reliable and standard time. They can be set up once and left to work for tens of years without any adjustment or power rundown.
