24、reakthroughs have transformed nanotech from sci-fi fantasy into a real-world. Applied science, and in the process, inspired huge investments by business, academia, and government. In industries as diverse as health care, computers, chemicals, and aerospace, nanotech is overhauling production techniq
25、ues, resulting in new and improved products, some of which may already be in your home or workplace. The inspiration for nanotech goes back to a 1959 speech by the late physicist Richard Feynman, then a professor at the California Institute of Technology, titled “Theres Plenty of Room at the Bottom.
26、“ Four decades later, Chad Mirkin, a Chemistry professor at Northwestern Universitys 34 million nanotech center, used a nanoscale device to etch most of Feynmans speech onto a surface the size of about 10 tobacco smoke particles. What accounts for the sudden acceleration of nanotechnology? A key bre
27、akthrough came in 1990, when researchers at IBMs Almaden Research Center succeeded in rearranging individual atoms at will. Using a device known as a scanning probe microscope, the team slowly moved 35 atoms to spell the three-letter IBM logo, thus proving Feynman fight. The entire Logo was less tha
28、n three nanometers. Soon, scientists were not only manipulating individual atoms but “spray painting“ with them as well. Using a tool known as a molecular beam epitaxy, scientists have learned to create ultra fine films of specialized crystals, built up one molecular layer at a time. This is the tec
29、hnology used today to build read-head components for computer hard drives. The next stage in the development of nanotechnology borrows a page from nature. Building a super-computer no bigger than a speck of dust might seem an impossible task, until one realizes that evolution solved such problems mo
30、re than a billion years ago. Living ceils contain all sorts of nanoscale motors made of proteins that perform myriad mechanical and chemical functions, from muscle contraction to photosynthesis. In some instances, such motors may be re-engineered, or imitated, to produce products and processes usefu
31、l to humans. How are these biologically inspired machines constructed? Often, they construct themselves, manifesting a phenomenon of nature known as self assembly. The macromolecules of such biological machines have exactly the right shape and chemical binding preferences to ensure that when they co
32、mbine they will snap together in predesigned ways. For example, the two strands that make up DNAs double helix match each other exactly, which means that if they are separated in a complex chemical mixture, they are still able to find each other easily. 41 It can be inferred that Richard Feynman has
33、 been _ now. （ A） dead （ B） decent （ C） prominent （ D） popular 42 Who proved that Feymans concept, “Theres Plenty of Room at the Bottom“ was right? （ A） Chad Mirkin at Northwestern University （ B） Researchers at Almaden Research Center （ C） Scientists manipulating atoms and “spray painting“ （ D） A p

No industry is spared. If you end up having to start over, in addition to starting your job search, there are seve
38、ral things you should take care of to make your transition a smooth one. First and foremost, clear up any misunderstanding about how and why you left your last job with your ex-boss.

39、planation. Agree on job titles accordingly. Also ask for a reference if you think your ex-boss will offer one and you trust that he or she will speak honestly about your performance. You should have a source of emergency cash that you can use in the interim. Dont panic and liquidate your stocks and
40、bonds just yet, be optimistic in your prospects while also be more frugal than usual. You should save money on not having to dry clean work clothes so often and eating less take-out lunches. Save money by not eating out at restaurants and watch videos rather than going to the movies every weekend. M
41、ake a note of your job hunting expenses, such as career counselors consulting fees and resume printing costs, and save the receipts. By next years tax-filing time, you could get deductions on your job-search expense (unless you left a job willingly or was a college graduate looking for your first jo

When you leave a job, the money can sometimes be kept with your ex-employer for a while. Its always a good idea to compare your new employers 401 (k
46、) plan with your old one. Every company offers different types of investment options, from overseas stocks to high-tech stocks and everything in between. If you do want to transfer the account to your new employer, you need to go to the human resources department and ask for forms that help you make
47、 the transition. Dont forget to ask for job leads from your ex-coworkers.
