Scientific Achievements

The amazing scientific advances [অগ্রগতি] humankind has made in a relatively [তুলনামূলক ভাবে] short period of time have been nothing short of extraordinary. Implanting [ভিতরে স্থাপন করা] a person with an artificial [কৃত্রিম] heart was an extraordinary step towards the development of heart transplant surgery. Cell phone that is useful and spreads [ছড়িয়ে পড়া] so fast has to be considered [বিবেচনা করা] one of the greatest inventions of all time. Now, people from street vendors to business executives in luxury cars, and from villagers to urbanites use cell phones. Today, we have computer that allows us to access the Internet, do word processing, use a calculator, watch TV, play games and do a host of other things. Today, we use satellites for GPS, TV, radio, weather tracking, military surveillance [নজরদারি], space exploration [অনুসন্ধান] and global communications, among other things. Putting a man on the moon is perhaps man’s most inspiring [উদ্দীপক] accomplishment [সাফল্য]; it opened the door to future space travel and led to a number of spin-off inventions including flame resistant textiles used by firefighters, invisible braces, improved satellite dishes, and better medical imaging. The web has revolutionized [বিপ্লব] the dissemination [প্রচারতা] of information, created a new multi-trillion dollar economic phenomenon [ব্যাপার], played a role in revolutions, and has interconnected much of the globe. Incredible advances in microchips have made it possible for them to be cheaply and efficiently [দক্ষতার সঙ্গে] used for calculators, personal computers, pet identification, automatic teller machines, satellites, pacemakers, cell phones, and microwave ovens among many other products.
