Greatest Scientific Achievements

We humans tend to forget how far we have come in a relatively short time. It was in the 1870s that we had our first home illuminated with electricity. Carls Lindbergh was only available 100 years ago to make its first transatlantic flight in 1927. Television did not spread until after World War II. In was LL. In other words, in a relatively short time by men, humanity does nothing but rare things. Perhaps it's as extraordinary as merely adapting to these incredible changes without realizing how completely our world has changed in a short time. In this sense, it is worth looking back at some of the incredible scientific advances we have made with the artificial heart over the past decade. There is nothing that will inspire people's interest. Dr. Berry Clark, a Seattle-based dentist, was the first to embed the Jarvik-7, a lifelong artificial art. The patient survived for 112 days, but it was a major step towards developing a heart transplant. One day, the high-grade sacrifice of artificial organs can be much longer and productive. When I arrived there, I borrowed lots of Robert Jervik's artificial heart. Mobile phones: Mobile phones were

since the end of the 19th century, but mobile phones only appeared in the 1990s. According to some estimates, more than 100 million people in Bangladesh and more than

.6 billion people worldwide have mobile phones. Everything that spreads very quickly and usefully must be considered one of the greatest inventions of all

Bangladesh.

hours. Twenty years ago, it was difficult to store even rural lines, let alone mobile phones. Today, all social class people use their mobile phones, from luxury car street dealers to businessmen, villagers to urban events. Since May 2015, Bangladesh has joined South Asian neighbours India (862 million) and Pakistan (122 million) on the list of countries with over 100 million mobile phone users. Other countries on the list are China (1 billion users), Russia, Brazil and the United States. Personal computers in Indonesia, Japan, Germany, Philippines, Nigeria,

We take for granted that there is a machine that accesses the internet, handles text, uses a calculator, watches TV, plays games and performs many other things. However, HR computers were only really needed when Microsoft Windows was open in 1985, and it's good that the internet wasn't too big without spreading HR computers the same as they are now.

First Communication Satellite: People on Earth can, of course, adopt

. Of course, in today's high-tech world of mobile phones, GPS and satellites high above Earth, you can communicate instantly. But it all began 50 years ago with balloons in a huge room.

Satellite Communications was born on July 10, 1962. On this day, the Telstar satellite began its journey into space, becoming the first active communication satellite. I wore my first transatlantic TV show. Telstar was built by a team at Bell Telephone Laboratory in the US and included many innovations, including the 3,600 solar collectors who launched transistors and satellites. Telstar produced 1

watts and handed out the first and private television photos on

1962 on July 11th. The satellite was able to carry voice calls and black and white TV channels from egg-shaped orbits. Today we use satellites from GPS, TV, radio, weather tracking, military surveillance, space research and global communications. Moon Landing: For thousands of

people dreamed of searching the sky and running through the moon. In 1969, Neil Armstrong first used this dream as part of Buzz Aldrin's Apollo 11 mission minutes later. Her performance has given people around the world hope for future space research. In fact, it's a very great performance, and there are still conspiracy theorists who argue that it's impossible. Taking a man to the moon is perhaps the most exciting performance of a human. It opened the door for future space travel and led to the invention of a series of spin-offs, including flame-proof textiles used by firefighters, invisible braces, improved satellite dishes, and better medical imaging.
