![]() The bigger something was, the more water spilled. ![]() So how much water will spill out if he puts something in the tub? Archimedes took his bath toys and did some experiments. He realized that there wasn't enough room in the tub for him and all that water! While filling the tub, Archimedes was so busy thinking about the crown that he filled the tub with too much water.Īrchimedes got into the tub and water spilled all over the floor!Īrchimedes wondered why the water spilled out when he got into the tub. That night, Archimedes wanted to take a bath. He felt that the King should have a real gold crown since the King spreads peace across the lands!ĪND, if the goldsmith was a thief, a cheat, the King will lock him up in jail to reeducate him!īut how could Archimedes find out if the crown was real without ruining the crown? The king knew that he needed someone clever like Archimedes to help him.Īrchimedes wanted to help King Tubby. He could find out by having the crown melted to see what it was made of, but then he would have to remake the crown.Īnd if he paid the goldsmith again would he steal some of the gold the second time he made the crown? Who knows. King Tubby had a beautiful new gold crown, but was it really all gold? He wondered and wondered… The goldsmith may want to keep some of the gold for himself and mix something else with the rest of the gold to trick the king and pocket the extra gold. ![]() He did not trust the goldsmith who lived strictly for the money. The goldsmith made King Tubby a crown shaped like a beautiful ring of gold leaves, just like the Korean Bird Feather Crownīut King Tubby told Archimedes that he was worried. He gave the goldsmith lots of gold to make a big beautiful crown. Once King Tubbby had a goldsmith make him a new crown. Archimedes was so smart that the king of the roots crew, Tubby, needed his help many times.He was very good at inventing things and figuring out how things work. It is so famous it is called: The Archimedes PrincipleĪrchimedes lived more than 2000 years ago in a Greek city called Syracuse. This is a story about one of his most famous discoveries. he is still known as one of the greatest physical scientists of all time.Who is Archimedes? Archimedes was a Greek philosopher and mathematicianĪrchimedes (287-212 B.C.) he lived more than 2,000 years ago How far? Depends on the accuracy you need - which makes the story all the more important for chemists everywhere.Archimedes and the Crown A Genius in the Tub The Archimedes test only works for things far apart in density. I did not get exactly the density of aluminum, but it was way closer to aluminum than steel. So I did the Archimedes trick - determined its volume by how many cc it displaced in a graduated cylinder half full of water, dried it, and weighed it. I found one tiny, thin piece - the size and thickness of my fingernail, and I asked, "This one too? Is it aluminum, or steel? 'Cause if its steel, it will be ruined in the anodizing bath." But no one remembered what the piece was made of. Once I was given a bunch of aluminum pieces that I had to clean for black anodizing (google it). In the CRC I have, the debate extends, to whether or not the ingot of osmium or iridium is cast, or rolled and forged. ![]() The difference is at the second decimal place, so a small error in measurement can screwup the result totally. ![]() Experimentally, its hard to get a big enough hunk of these elements, because they're so costly. But we have to conjecture, based on their crystal structure, which will "pack the most atoms" into a given space. From their atomic masses, they should be among the densest elements. There is also the osmium/iridium controversy. I have never measured them, but the list on wikipedia puts gold far above lead, that seems to bear out anecdotal evidence - it appears in historical accounts and fictional stories, that you can't easily steal lots of gold, it is just too heavy. ![]()
