Evidence from the sand supports this idea.Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.
However, physicist Joseph West thinks there might have been a simpler way,who led the new study.West said,“I was inspired while watching a television program showing how sleds might have helped with pyramid construction.I thought,‘Why don't they just try rolling the things? ’” A square could be turned into a rough sort of wheel by attaching wooden poles to its sides, he realized.That, he notes, should make a block of stone “a lot easier to roll than a square”.
So he tried it.
He and his students tied some poles to each of four sides of a 30kilogram stone block.That action turned the block into somewhat a wheel.Then they placed the block on the ground.
They wrapped one end of a rope around the block and pulled.The researchers found they could easily roll the block along different kinds of paths.They calculated that rolling the block required about as much force as moving it along a slippery(滑的)path.
West hasn't tested his idea on larger blocks,but he thinks rolling has clear advantages over sliding.At least,workers wouldn't have needed to carry cattle fat or water to smooth the paths.
文章大意:本文讲述的是对金字塔石块运输方式的研究。大多数研究人员认为古埃及人可能是把石块放在滑板上滑至目的地。现在还有人认为古埃及人还有可能是在巨石四周捆绑木棒,然后将石块滚至目的地。
