The design of Heng's seismograph was indicative of Chinese artistry. The kettle sported eight dragonheads arranged in eight directions around the outside rim. Each head held a ball in its mouth. At the base of the vessel were eight corresponding toads with their empty mouths open. The "toothed machinery and ingenious constructions" inside the device were hidden. Actually it was an inverted pendulum that reacted to the slightest tremor of the earth. The pendulum swung, tapping a mechanism that ejected one of the balls from the corresponding dragonhead. The ball would fall into the waiting toad's mouth sitting directly under it and make a loud http://www.answers.com/topic/clanglang. Whichever toad had the ball indicated the direction of the earthquake's location.
To say in the least, a tremor from an earthquake will cause one of the balls to drop from the dragon's mouth and land in the frog's mouth. The direction of the earthquake can be said from which frog's mouth the ball lands into.
As to not make anyone mad and to get things from everyone.
That is hardly the type of thing anyone would make a list of.
She worked very hard, and got good grades in school. She constantly did her homework and chores, without anyone telling her twice. YOU GO EMPRESS WU!
I would use a pencil and paper. You could use a pen if you prefer, but you might have to make corrections. Or you could just ditch the paper and use a computer. Any word processing program would work.I know you're going to think this answer is facetious, but honestly, short of writing the speech FOR you, how do you expect anyone to answer this question?
hehehehe
A person named Zhang Heng is known to be the first to make a prototype of it. He came from China back in 132 AD.
The seismograph was not discovered, it was invented in 132 CE by Zhang Heng, but most modern seismographs are derived from a design by John Milne, James Alfred Ewing, and Thomas Gray, who worked in the late 19th century.
yes
to make sure that every child is educated.
it would change to make the record look smaller
because she can make it into paper and sell it to make more money.

Well you know when you write a sentence, the paper stays in one place while your hand moves the pen. But in a seismograph, it's the pen that remains stationary while the paper moves. Why is this? All seismographs make use of a basic principle of physics: Whether it is moving or at rest, every object resists any change to its motion. A seismograph's heavy weight resists motion during a quake. But the rest of the seismograph is anchored to the ground and vibrates when seismic waves arrive.

Ba means eight in Chinese and Gua means diagram (specifically a trigram, three whole and/or broken lines which combine to make the 64 hexagrams of the I Ching or Yi Jing - Book of Changes). Zhang means palm. Thus a "Bagua Zhang" means Eight Trigram Palm, a potentially deadly martial art.
You can't "make" anyone comfortable with anyone.
I dont know about newer ones but older ones had a pen hovering a piece of paper and the siesmic waves would make them move.
