Tsunami Defined
Tsunami is a Japanese term that describes a large seismically generated sea wave which is capable of considerable destruction in certain coastal areas, especially where underwater earthquakes occur. In Japanese, "Tsunami" means "Harbor Wave" or "Wave In The Harbor" It is now internationally accepted as the term that defines a "Seismic Seawave." In South America, the term "Maremoto" is frequently used to describe a Tsunami. Tsunami is pronounced: (sue-NAM-ee) Tsunami's have been incorrectly referred to as "tidal waves." A tidal wave is a non-technical term for a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth (high water is the crest of a tidal wave and low water is the trough). Tsunami's are formed by a displacement of water. This can come from the slippage of the boundaries between two tectonic plates, volcanic eruption, under-water earthquake, or even landslides. Out in the open ocean, Tsunami's might only be 1 meter in height, but as it reaches the shore in shallow water, it can rise to heights of 15-30 meters or more. Think about how a normal wave comes into a shore: the water moves away from the shore and then comes crashing back. This movement "heightens" the destruction power of a Tsunami. Tsunami's can also reach speeds ranging from 400 to 500+ miles per hour? about the same speed as a jet airliner. The enormous energy that a Tsunami can possess allows it to travel across entire oceans. They often proceed as an ordinary gravity wave? having a 15 to 60 minute intervals. From a destruction perspective, Tsunami's have cost not hundreds of thousands, but millions of human lives over the recorded history of Earth.

Increasing Human Brain Power, Concept Is it possible to increase the human brainpower? Not just become smarter, but actually more power and energy? Some say yes and NASA is working on ways to do just that, the applications are endless; from boosting the immune system to higher cognitive processing.The human brain if it were run at a higher RPM at night by use of noise could increase the bio-systems abilities while sleeping?

Humans and Bees Go Back a Long Way The ancient history of of man and bees has been writen about for thousands of years. Specifically the human history and the use of Bee's Wax is truly fascinating. Where Do Insects Go When It Rains? Have you ever wondered where insects go when it rains? We have all seen a poor unfortunate spider washed down the plughole so we know how vulnerable they are to rushing water. Surely then, isn't rain one of their worst enemies?Sorry, but this is one of these "it depends" things. Science Fiction by Arthur C Clarke It is difficult to have a discussion with someone about science fiction if they are not familiar with the works of Arthur C Clarke. The concepts are not too awfully difficult to understand and not nearly as complex as reading Issac Asimov for the science fiction novice and anyone can enjoy Mr. Many Sci Fi writers have discussed Earthquake predictions Cal Tech along with the Universities in Japan are on the leading edge of this new technology and it is quickly becoming a reality. Soon we will know months in advance of an expected quake and the precise time maybe known hours or minutes before it actually comes. Saving Private Ryan in Iraq - Stop the Bleeding I propose that we give soldiers an ultra thin material, which will either be an undergarment to their uniform or incorporated as a liner within that uniform.

Sounds like kids stuff, yet is has some incredible applications for other things. For instance we could use Whispering Windows and Talking Glass Technologies to propel helium filled beach ball. What are the Biggest Solar Projects? Solar power will be necessary for space exploration and off planet colonies on the moon and Mars in the next few decades and our advances here on Earth will assist us with the knowledge we need to power them up. Some may not realize but we have come a long way in our solar technology in the last few decades and we are now ready to take this experience and knowledge to the next level; to build something out of this world.

Life on Mars, Warm Water Under our Ice Caps, Evidence, Microbes under Our Feet Well many people out there are asking is there really life on Mars? Our Thinking Group has been asking not if, what type?An article I remember reading and article in Astronomy Magazine back in 1996 that read was there life on Mars and it was an article about a meteorite that landed here on Earth and it was found in 1984 in Antarctica in the Allen Hills ice fields, like I even know where that is? It had bacteria fossils and remains of bacteria that lived about 3.6 billion years ago and the meteor appeared to have come from Mars.
