Some of the best devices and technologies that we prefer today were not the same before. Earlier, humans had invented new gadgets that were difficult to use in the beginning but later, with additional changes brought great machines for the world. So, we will now learn about the top 10 highly essential devices in our history.
1. COMPASS:
The Compass took an important role for Chinese in and around 1050 BC, for which they invented it for navigational and spiritual purposes. Initially, a compass is from lodestones, deriving from iron ore. The invention of the electromagnetic modern compass was from 1825. It is one of the essential devices in our history, which shows four directions, latitude, longitude, and altitude speed.
2. CELLULAR PHONES:
One of the vast changing technologies is cellular phones. Long before our current trend of mobile phones, there were a lot of payphones, and contacting someone even at times of emergency was hard. As technology improves, modern mobile phones came into existence. Our lives became so simple that we can do anything possible from mobile, even from homes such as chat, text, SMS, video calls, banking, and searching for jobs globally.
3. SONY DISCMAN D50:
After the success of Sony Walkman, the company brought the idea of portable CD player Discman D50 in 1984. Discman was the first compact CD player, which threw away the music cassettes within a decade. The Discman CD was trending till the 90s, and in 2000, the name Discman turned into Walkman worldwide. Till the iPod became popular, Sony hit millions of sales in their CD player.
4. AUTOMOBILE:
German inventor Karl Benz did the foundation for today’s modern cars in 1886. Before the 20th century, cars were not well-known. Henry Ford invented the Ford car using some technologies from the general motors. Henry’s automobile technology brought a worldwide reflection in cars. From that time, oil and steel industries became trending, and many got new jobs in the fields of the automobile.
5. LIGHT BULB:
We search for the best-LED bulbs for our office, home, and shop, but the basic idea of using a light bulb was 150 years ago. The bright invention of the electric bulb came in the 1800s by Humphry Davy. But Thomas Alva Edison and Swan were the patent holders for the first light bulb in 1880. In the middle of 1980, CFL bulbs were popular in the market. But since CFL was heavy, high cost and gave low output and led to inconsistent performance. Currently, the LED bulbs are energy-saving and prominent in their performance.
6. BATTERY:
The first-ever battery was 2000 years old from the Parthian empire. They used clay jar filled with a vinegar solution in which, copper cylinder with an iron rod was inserted. The electrochemistry founder Alessandro Volta developed the first electric battery. From the history in 1859, a battery has been a remarkable change with the first rechargeable ones that were based upon the lead-acid by French Physician Gaston Plante. Another developed version of the Nickel-Cadmium battery was developed in 1899 by Waldemar Jungner.
7. TRANSISTOR:
Transistors are the primary inventions in the field of electronic devices like television, mobile phones, computers, and laptops. In the beginning stages, the field-effect transistor was developed, but its working was not superior In 1947, Bell laboratories made their first transistor that was developed by Nobel Prize winners John Bardeen, Walter Brattain, and William Shockley.
8. AUTOMATED TELLER MACHINE:
The Automated Teller Machine is one of the imperative inventions of history. According to the ATM Industry Association, there are 2.2 million ATMs available currently worldwide. Using ATM, we can do as many transactions requiring such as cash withdrawal, balance checking, and purchasing anything through cards. John Sheppard –Barron brought this brilliant idea from a London Bank called Barclays. Earlier, they were using paper vouchers instead of plastic cards. Now, banking has been even simpler using e-banks.
9. ROBOT:
Robotic Technology is well-liked worldwide, presently from cooking to surgery. Around 3000 B.C, a human figurine was used to strike bell per hour in Egypt for water clocks. It might be the first mechanical design to bring more such devices to the world. But, Robotics became popular scientifically in the 20th century. The first programmable robot’s name was ‘Unimate’ from ‘Universal Automation.’ Robotics is the invention that changed the world totally and is seen with a better hope for the future.
10. ROKU NETFLIX PLAYER:
Netflix and video streaming boxes began their journey in 2010. The first remote had some lack of features, and then the box made many software updates that were like by people. Roku offers thousands of channels with the main players of all time.
