Archimedes


Who is Archimedes?
Archimedes Archimedes English world and the nature of Raaziatold in 287 BC. M., in Syracuse, and is considered one of the main thinkers of ancient times, and our view of physics based on the model developed by Archimedes.
What did Archimedes in the prime of youth?

Like most young people then traveled to Alexandria and then to Greece applied to study

What is the most important discoveries of Archimedes?

And said of him sporting world Fredch Gauss He is one of the greatest three in Mathematical Sciences with both Isaac Newton and Ferdinand Aasnstan., And his discoveries also radio and TV.

And now we take a short story claimed ..

King Greek Heron is making a crown of pure gold, and entrusted the task to the jeweler Maher after him with a certain weight of gold. And timely receipt King crown, and was impressed with skill and precision industry implementation .. However, helplessness doubt that the jeweler had stolen part of the gold, and that the mix of gold by silver to maintain weight, and I did ploy to cover up heinous. I turned to King philosopher Archimedes close (d. 212 BC)., And asked him to provide a solution to this dilemma, and find a way by which to know the truth about it. The dominant issue on the thinking of the Greek philosopher and kept turning it left and right; was Archimedes known density of pure gold, a gold weight per unit volume, Flo was able to measure the size of the crown to have facilitated the task, but realized in the case of whether the crown made of pure gold or mixed with silver . But what a way to measure the size of the crown of creation wonderful with all its technical meanders attractive, aesthetic forms of disparate, and overlapping geometric patterns?. If Archimedes could be melted crown, and then determine the size of liquid gold by a pot-sized known for operation ended .. But anger melting Crown King Greek and raises Hfazth!. Had that beats can Archimedes crown hammer until it turns into a rectangular mold for he could see the size and end the confusion .. But the king will not be happy at all smashed his crown, and convert it to a mere piece of pale landscape .. Rectangular!. Thus, the issue has become the main concern of the crown Greek philosopher, and became two lieutenant him wherever tomorrow and started. One day, while he is in the bathroom Note that whenever revealed his body in a tub of water rose water more and more; any body that has replaced some of the water in the tub. Suddenly, lightning solution to the problem of the crown in front of Archimedes, and proved him an effective means to overcome the dilemma that ran his mind and the mind of sovereign, and jumped Archimedes of the bathroom, and rushed through the streets of the city naked, he says: "I've found .... I've found." I have realized that the volume of water Archimedes joke in the basin of water equal to the volume of the submerged part of his body in the tub, and hurried to bring Archimedes blocks of pure gold and the other of pure silver and make weight each equal to the weight of the crown doubtful ordered him .. He then immersing each of these three blocs (gold, silver and Crown) in a vase filled with water, and taking water displaced and measured the size of each of the three cases. And to conduct this experiment discovered that Archimedes amount of water that Ozahaa crown was larger than that amount, which shifted the mass of pure gold, and less than the amount of water that dislodge a piece of silver. In this way Archimedes concluded that the crown was not made of pure gold and pure silver but it was a mixture of Almadnyin. Thus is unveiled jeweler cheater .. Not tell us what the history books by the solution of punishment
