who invented tea?
did you know that tea ,the most popular drink in the world ,was invented by accident ? although tea wasn't brought to Western world until 1610, this beverage was discovered over therr thousand years before that, According to an ancient CHINESE legend, the emperor Shen Nong disconered tea when he was boiling drinking water over an open fire .some leaves from a nearby bush fell into the water and remained there for some time . the emperor noticed that leaves in the water proced a pieasant smell. later he decided to taste the hot mixture ,it was quite delicious. and in this way, one of the world's favorite drinks was invented.
People often have ideas for inventions that are quickly dismissed or overlooked, only to have someone else take advantage of a similar idea and make large sums of money. If you dream about becoming a famous inventor, take your idea one step further. Spend some time to determine if it would sell on the market.
Come up with an idea for a new proct. The invention can be created from scratch, or you can modify an existing proct to work in a different way. For example, recycle materials in an innovative way, such as using plastic storage containers as light fixtures. In order to be patentable, the invention must satisfy the requirements of being novel and non-obvious, which means new and never seen before, and markedly different than the most similar invention. You cannot get a patent on an invention that uses a different color or size than a previous invention.
Determine if there is a need for this proct by finding out if similar procts exist through market research. If you invented a type of cookware, research different types of cookware. Does a similar proct perform the same type of function? Find out if there is an existing patent on your idea by searching the patent databases .
Leonardo da Vinci (1452-1519), an Italia Renaissance artist, nature scientist, engineer and the founder of mechanics theory, made the impressive contributions to the forming of classical hydraulics and fluid mechanics.
Da Vinci's philosophy idea is near to materialism. He thought that everything in the world must obey the objective nature rules, knowledge came from sentience and it was important to do theory generalization. He emphasized that mathematics and mechanics were the basis of nature science. He also had many great fancies and discoveries on military affairs, water-conservancy, civil engineering and mechanical engineering
Da Vinci's mechanics research work was not only theoretic. He also designed lots of machines and appliances with the principles of mechanics and mechanical engineering. He took part in the design and construction of canals, water conservancy and architectural engineering. Based on the study of bird wings motion, he schemed out an aircraft in 1493 for the first time.
Da Vinci had quite a lot of rare manuscripts on hydraulics, which was published as Water Motion and Survey after he died.

TRIPOLI, April 30 (Xinhua) -- Saif al-Arab Gaddafi, youngest son of Libyan leader Muammar Gaddafi, was killed in NATO's strike against Gaddafi's house, said a spokesman of the Libyan government.
The NATO attack against Gaddafi's house resulted in the deaths of Saif al-Arab Gaddafi, 29, youngest son of Gaddafi, and three of Gaddafi's grandchildren, said Mossa Ibrahim, the government spokesman.
The leader himself and his wife, who were in the house, were in good health, while other people injured in the attack, said the spokesman.
This is a direct operation to assassinate the leader, said the spokesman.
The attacks had no legal or political foundations, he said, saying the strike was a violation of the international law.
Asserting he would not leave, embattled Libyan leader Muammar Gaddafi floated on Saturday a proposal for a ceasefire and negotiations in a televised speech.
He said that all parties concerned should follow the truce, and the NATO forces must stop their attacks.
Gaddafi ruled out the possibility that he will quit and leave Libya, which he has been ruling over the past 41 years.
Gaddafi slammed the air raids by NATO, which started to attack his fortified compound in the capital Tripoli.
The world's major powers, the UK, the US and France, started on March 19 to launch strikes from the air and sea against Gaddafi's forces after the UN Security Council passed a resolution to impose a no-fly zone over Libya and authorize "all necessary measures" to protect civilians in Libya.
