题目：Thomas Harroit — the discovery of refraction 内容：光的折射 题型：配对题如填空题8
文章：(文章为部分回忆节选，仅供参考)
A When light travels from one medium to another^ it generally bends7 or refracts. The law of refraction gives us a way of predicting the amount of bending. Refraction has many applications in optics and technology. A prism uses refraction to form an image of an object for many different purposes7 such as magnification. A prism uses refraction to form colors from an incident beam of light Refraction also plays an important role in the
information of a mirage and other illusions
B A contemporary of Shakespeare. Elizabeth I. johannes Kepler and Galilei Galileo.
Thomas Harriot (1560-1621) was in English scientist and mathematician. His principal biographer. J. W. Shirley, was quoted saying that in his time he was "England’s most profound mathematician, most imaginative amd methodical experimental scientist ".As a mathematician, he contributed to the development of algebra, and introduced the
symbols of *>" and M<" for "more than^1 and ^less than f,. He also studied navigation and
astronomy. On September 17.1607. Harriot observed a comet later Identified as Hailey-s. With his painstaking observations, later workers were able to compute the comet's oibit. Harriot was also the first to use a telescope to observe the heavens in England. He made sketches of the moon in 1609. and then developed lenses of increasing magnification. By April 1611.he had developed a lens with a
E experiments on refraction in the 1590sr and from his notes it is clear that he had discovered the sine law at least as early as 1602. Around 1606. he had studied dispersion in prisms^ predating Newton by around 60 years^ measured the refractive indices of different liquids placed in a hollow glass prism7 studied refraction in crystal spheres^ and correctly understood refraction in the rainbow before Descartes.
F As his studies of refraction. Harriots discoveries in other fields were largely unpublished during his lifetime, and until this century. Harriot was known onl}^ for an account of his travels in Virginia published in 1588. and for a treatise on algebra published posthumously in 1631. The reason why Harriot kept his results unpublished is unclear. Harriot wrote to Kepler that poor health prevented him from providing more informatiorv but it is also possible that he was afraid of the seventeenth century's English religious establishment which was suspicious of the work carried out by mathematicians and scientists.
G After the discovery of sunspots. Harriot's scientific work dwindled. On July 2 of 1621. Harriot died in London. But his story did not end with his death. Recent research 9 has revealed his wide range of interests and his genuinely original discoveries.What some writers describe as his 'thousands upon thousands of sheets of mathematics and of scientific observations^ appeared to be lost until 1784 when they were found in Henry Percy's country estate by one of Percy's descendants. She gave them to Franz Xaver Zach. her husband's son s tutor. Zach eventually put some of the papers in the hands of the Oxford University Press7 but much work was required to prepare them for publication^ and it has never been done. Scholars have begun to study themr and an appreciation of Harriots contribution started to grow in the second half of the twentieth century. Harriot's study of refraction is but one example where his work overlapped with independent studies carried out by others in Europe, but in any historical treatment of optics his contribution rightfully deserves to be acknowledged.
