period 3 listening and speakingthe questions may be useful to discuss the scientific job,the expressions may help you to discuss your future scientific job.what job do you want to do?what education will you need?what personality will be needed?what work experience would be useful?how long will the training take?how will you prepare for this career?i always wanted to...because...the experience i will need is...i might find it difficult to...i need to practise...my greatest problem will be to...i will need to be/become patient, creative, hard-working, co-operative, confident, brave...
research and activitiesafter class, use the library or the internet to find out facts about important women scientists in medicine, physics, chemistry, biology, astronomy or mathematics.there are very useful websites (including the“biographies of women mathematicians website”).prepare a talk on your chosen scientists.remember to include some information about their life, their achievements and why they are considered important in science history.then give your talk to the class.

euler, leonhard(born april 15, 1707, basel, switz.died sept.18, 1783, st.petersburg, russia)swiss mathematician and physicist, one of the founders of pure mathematics.he not only made decisive and formative contributions to the subjects of geometry, calculus, mechanics, and number theory but also developed methods for solving problems in observational astronomy and demonstrated useful applications of mathematics in technology and public affairs.euler’s mathematical ability earned him the esteem of johann bernoulli, one of the first mathematicians in europe at that time, and of his sons daniel and nicolas.in 1727 he moved to st.petersburg, where he became an associate of the st.petersburg academy of sciences and in 1733 succeeded daniel bernoulli to the chair of mathematics.euler devoted considerable attention to developing a more perfect theory of lunar motion, which was particularly troublesome, since it involved the so-called three-body problem—the interactions of the sun, moon, and earth.(the problem is still unsolved.) his partial solution, published in 1753, assisted the british admiralty in calculating lunar tables, of importance then in attempting to determine longitude at sea.one of the feats of his blind years was to perform all the elaborate calculations in his head for his second theory of lunar motion in 1772.throughout his life euler was much absorbed by problems dealing with the theory of numbers, which treats of the properties and relationships of integers, or whole numbers (0, ±1, ±2, etc.); in this, his greatest discovery, in 1783, was the law of quadratic reciprocity, which has become an essential part of modern number theory.
