Top 10 scientific discoveries
We citizenry tend to forget how far we’ve come as a species during a relatively short period of your time. it had been only within the 1870s once we had the primary house that was lighted with electricity. Cars just began to become available 100 years ago. It’s one of the top 10 scientific discoveries. Lindbergh made the primary trans-Atlantic flight in 1927. Televisions didn’t become widely available until after war 2. In other words, the advances humankind has made during a relatively short period of your time are nothing in need of extraordinary. Perhaps even as extraordinary is how we tend to easily adapt to those incredible changes, not realizing how completely our world has been altered during a short span of your time. thereupon in mind, it’s worth looking back at a number of the amazing scientific advances we’ve made within a previous couple of decades.
here are the all scientific discoveries
CELL PHONES: Today, by some estimates, more than 100 million people in Bangladesh and more than 4.6 billion people worldwide have mobile phones. Anything that is useful ads spreads so fast has to considered one of the greatest inventions of all time. Just two decades ago, in Bangladesh, even landlines were difficult to obtain, let alone mobile phones. Since May 2015, Bangladesh joined its South Asian neighbors India ( 862 million) and Pakistan ( 122 million )
THE PERSONAL COMPUTER: Today we take for granted that we have one machine that allows us to access the internet, do word processing, use a calculator, watch TV, play games and do a host of other things. But the personal computer only became available to consumers in 1974. It is one kind of top 10 scientific discoveries. Things really took off when Microsoft windows were introduced in 1985 and it’s good that it was since without the prevalence of personal computers, the internet wouldn’t have had nearly as big an impact as it has ever since.
THE FIRST COMMUNICATION SATELLITE: People on Earth may take for granted today the high tech world of cell phones, GPS, and the satellites high above the planet that make instant communication possible. 10 July 1952 marked the first-ever active communications satellite. It carried the first live trans-Atlantic TV broadcasts. Telstar was built by a team at Bell Telephone Laboratories in the USA and incorporated many innovations such as the transistor and the 3600 solar panels that powered the satellite. Telstar produced 14 watts and relayed it’s first and non-public on 11 July 1962. It is one kind of top 10 scientific discoveries. The satellite could carry 600 voice calls and one black-and-white TV channel from an egg-shaped orbit.
THE MOON LANDINGS: For thousands of years, human beings had looked to the heavens and dreamed of walking on the moon. In 1969, as part of the Apollo 11 mission, Neil Armstrong became the first person to accomplish that dream, followed only minutes later by Buzz Aldrin. Their accomplishment gave people around the world the hope of future space exploration. It is one kind of top 10 scientific discoveries. In fact, it was a feat that was so fantastic that there are still conspiracy theorists who insist it could not be possible. Putting a man on the moon is the most inspiring accomplishment for the man. It opened the door to future space travel.
THE INTERNET/WORLD WIDE WEB: Today, just 22 years later, the web has revolutionized the dissemination of information, created a new multi-trillion dollar economic phenomenon, played a role in revolutions, and has interconnected much of the globe. It is one kind of top 10 scientific discoveries. It has also made it possible for people all over the planet to reach out and touch someone.
