had an appetite for knowledge.Despite his wealth, he worked to make a career in science.He made a first journey to study wild plants in 1766.His next expedition was the great voyage with James Cook to Oceania.In 1768, the Royal Navy appointed James Cook as the commander of the Endeavour to take members of the Royal Society on an expedition to Tahiti.According to the instructions given to Captain Cook,the expedition had three goals.The primary goal was to study the passing of the planet Venus across the sun.This would give astronomers a change to calculate the distance between the earth and the sun.Secondly the purpose of the expedition was to record, classify and describe all plant and animal life observed during the trip.Thirdly, Captain Cook received secret instructions to search for an unknown southern continent.As astronomy was one of the most important branches of science,it was the British government that paid for all the equipment and expenses for that of the expedition.Since the government would not pay for such a new field of science as botany, Joseph Banks,at the age of 25, had to supply about10,000 of his own money to equip the expedition.On their three-year voyage, Joseph Banks did not only study and describe new plants he found,but also looked out new economic species: plans that could be grown in England or other parts of the world to produce crops that could be sold.Banks was the first to move crops from one continent to another on a large scale,helping to develop local economies with these new imports.Some plants that were spread over the globe in this way include cocoa, hemp and tea.The Endeavour, returned to England in 1771.The voyage had been a great success.Wonderful discoveries had been made of strange new lands, cultures, animals and plants.After that Captain Cook made two more voyages around the world, but Joseph Banks never undertook another.From behind his desk, however, he was involved in enterprises such as the exploration of Africa and the settlement of Australia.In 1778, Banks was elected president of the Royal Society, a position he held for 42 years.During these years Banks helped to develop the royal gardens at Kew into one of the greatest botanical gardens in the world.He accumulated a great deal of knowledge about plants and agriculture.In growing strawberries Banks went back to the abandoned practice of spreading straw under the fruit to reduce the necessary amount of watering.He also built a greenhouse to experiment with growing pineapples.It was Joseph Banks who made Kew a centre of scientific and economic research.INTEGRATING SKILLSReadingWILDLIEF AND GRARDEN ROSESIn his youth Charles Darwin enjoyed all the freedom to experiment and do whatever he liked.The study of physics, chemistry, and later botany, was his hobbyAt the age of 22, Darwin was invited to join the scientific expedition on the Beagle.we use words likememory,storeandcut and paste.The words are useful,but they are not quite true.A computers memoryis similar to human memory in some ways,but it is also very different.A computer does keep information in its memory,but that is clearly different from other kinds of storage.We do cut and paste,but we dont use scissors or glue.Using familiar words makes it easier for us to understand and use a new tool,but it may also make it more difficult for us to use the new invention in the best way.After all,what makes a new invention such a wonderful thingis that it allows us to do something we could not do before.Science is not just about electronics and plastic;it is also about how we think about the world.Now that we are developing new technology at such a high pace,the true challenge is to find new ways of using it.How will we use computers in the future?How will we use the Internet?The real function will only be knownonce we discover new ways of thinking about the technology.Integrating skillsReading InventionsComputers taht use light instead of electricity,smart clothes taht can make phone calls and play music,house paints that change colour with the seasons,e-paper and ads that speak to you-the list of amazing new inventions that seem to be just around the corner is long and inspiring.How many of these new technologies will actually become reality remains to be seen,but it is clear that the next fifty years will be exciting.Here is a look at some of the new ideas that may shape our future.Now you see it,Now you dontResearchers in Japanhave invented a kind of paint that makes things invisible.It may sound incredible,but the new paint reflects light in such a way that the human eye is fooled.The technology behind the paint is fairly simple:instead of letting the light rays bounce back in the normal way,the paint sends the light back to the source.It is as if a basketball backboard was madeso that a ball thrown at an anglewould bounce right back at teh person throwing it.The paint does not really make things disappear,but by changing the way the light bouncesit does make it pos
