剑桥大学里的数学桥英文介绍
急用,
The Mathematical Bridge is the popular name of a wooden bridge across the River Cam,between two parts of Queens' College,Cambridge.Its official name is merely the Wooden Bridge.
The bridge was designed by William Etheridge,and built by James Essex in 1749.It has been rebuilt on two occasions — 1866 and 1905 — but has kept the same overall design.
The title of 'Mathematical Bridge' was also given to one of the former bridges of the Cam between Trinity and Trinity Hall,also designed by James Essex,where Garret Hostel Bridge now stands.
There are several myths surrounding the construction of the bridge:
That the bridge is of Chinese origin and that its design incorporates some form of special mathematical technique from which it derives its name.
That the bridge was designed and built by students.It was so perfect that the planks were laid one on top of the other and held together by their weight and the angles by which they were put together.The professors were so intrigued and in awe of its architecture that they took it apart to see how it was built.Their downfall was that they could not piece it back together again and therefore the bridge is now held together by nuts,bolts and screws.
That the bridge was designed by Isaac Newton,but that he did so without the need for bolts to hold the wood together - the story of college members then dismantling it and being unable to reassemble it is also part of this version of the myth.This version is unlikely to be true because Newton died in 1727,22 years before the bridge was constructed.
Tellers of these myths rarely elaborate on what these mysterious mathematical techniques might have been.

这是另外一段介绍
The bridge was built in 1749 by James Essex the Younger (1722-1784) to the design of William Etheridge (1709-1776).It has subsequently been rebuilt to the same design in 1866 and 1905.
The red-brick building on the right is the President's Lodge (ca 1460,the oldest building on the river at Cambridge).On the extreme right is the Essex Building (1756-60).Behind the trees on the left is Cripps Court (1974).
For those who have fallen prey to the baseless stories told by unscrupulous guides to gullible tourists,it is necessary to point out that Isaac Newton died in 1727 (biography),and therefore cannot possibly have had anything to do with this bridge.Anyone who believes that students or Fellows could have disassembled the bridge (and then failed to re-assemble it,as the myth runs) cannot have a serious grasp on reality,given the size and weight of the wooden members of the bridge.The joints of the present bridge are fastened by nuts and bolts.Earlier versions of the bridge used iron pins or screws at the joints,driven in from the outer elevation.Only a pedant could claim that the bridge was originally built without nails.Other baseless stories are that Etheridge had been a student,and/or had visited China.
