Attempts for aircraft in the 19th and 20th centuries
Otto Lilienthal, a German engineer, was the first to design and build a viable manned glider capable of long-distance flight. In 1891, while studying aerodynamics, he focused his efforts on creating a flying glider.
Otto Lilienthal was enthralled by the prospect of manned flying aircraft in the future. He released an aerodynamics book in 1889. His studies of birds in flight inspired him to write this book. This book was later used by the Wright Brothers to construct their famous aircraft.
In a plane disaster, Otto Lilienthal sadly died. He lost control of the craft due to strong winds, leading it to crash back to Earth. After his 2,500th flight, this happened.
Other important dates in aviation history occurred in 1891 when the aerodrome flew about a mile after running out of gasoline. Samuel Langley designed the aerodrome. He is a scientist and an astronomer who saw the necessity for power in man’s desire for flight. Putting up a power plant for a glider was his biggest contribution to flight. His experiments with whirling arms and a steam engine resulted in the aerodrome plane model.
Langley was awarded a $50,000 grant with the goal of building a full-scale aerodrome. Because it was too hefty, this plane crashed. Because of this disappointment, Langley gave up his dreams of flying. Langley worked at the Smithsonian Institution in Washington, D.C. as a director.
The Herring – Chanute biplane was created in 1894 by Engineer Octave Chanute. This aircraft was the inspiration for the Wright brothers’ biplane. Inventing planes became Octave Chanute’s hobby after being inspired by Otto Lilienthal.
Chanute gathered a vast amount of technical data about aviation achievements and pioneers from throughout the world. In 1894, this knowledge was compiled into a book called “Progress in Flying Machines.” This book was used as a foundation for many of the Wright Brothers’ experiments. Chanute became acquainted with the Wright Brothers and wished them well in their endeavors.
On the shoulders of the aviation pioneers, Orville and Wilbur Wright stood. They studied the pioneers’ work and growth in the field of flight for several years. They study the topic by reading books and other materials. Then it was time to put their hypotheses about balloons and kites to the test. They discovered how wind interacts with the surface and with flying. Experiments with various glider shapes and how to control their flight followed.
It was placed inside a wind tunnel to evaluate the various wing forms and tails. They also conducted tests on the Outer Banks dunes of North Carolina, where they determined the most promising glider shape. When this happened, they concentrated their efforts on developing an engine and mechanism for launching and launching the glider.
The “Flyer” was the first heavier-than-air flight plane, and Orville Wright was the first man to fly it, on December 17, 1903, at Kitty Hawk. It took off from ground level and flew 120 feet to the north of Big Kill Devil Hill in only twelve seconds. The total weight of the Flyer was 650 pounds.
Human flying has now become a reality. During the next century, increasingly improved aeroplanes were developed. These planes were created for a variety of purposes, including transporting people, freight, military personnel, and armaments.
According to Wilbur and Orville Wright, all advancements in aviation during the twentieth century were founded on this inaugural flight at Kitty Hawk.
On Tuesday, the Reserve Bank of India (RBI) announced UPI123Pay, a new digital payment option for feature phones based on the Unified Payments Interface (UPI). The UPI system has so far been restricted to smartphones with internet access. India’s mobile phone population is estimated to be at 180 million. 78 crore of these people have smartphones, while the remaining 78 crores have feature phones. Due to the phone they use, tens of thousands of users have been unable to do UPI transactions. The central bank of India introduced this new payment mechanism to incorporate all such users and bring them into the mainstream of digital payments.
“UPI123Pay would enable NPCI to accomplish its goal of a billion or more daily UPI transactions,” said Biswamohan Mahapatra, head of the National Payments Corporation of India (NPCI), the country’s umbrella organization for retail digital payments.
Working of UPI on Feature Phones?
Users will be able to conduct UPI transactions on feature phones using UPI 123Pay. Except for the scan and pay UPI option available for smartphones, consumers will be able to use all other functionalities. Transactions with the new digital payment mode don’t require an internet connection. To utilize the UPI 123Pay service, people must link their bank accounts to their feature phones. People with feature phones can now use the UPI 123Pay option for a variety of payments, from person to person to the merchant. UPI 123Pay would employ Hindi and English as their primary languages at first.
“We feel that the novel functions available on feature phones would give UPI a boost in many geographies across the country, transforming the way payments are perceived,” Mahapatra said.
UPI: India’s Most Popular Payment Method
In recent years, UPI has become one of India’s most popular payment methods. UPI is the country’s single largest retail payment system in terms of transaction volume.
“A substantial portion of digitalization is limited to people with smartphones, notwithstanding our tremendous growth in digital payments.” “About 40 crore feature phone users had limited access to digital payments,” said T Rabi Sankar, deputy governor of the Reserve Bank of India. He stated that the goal is to attract a significant number of feature phone users into the UPI payment system.
“To further popularise the usage of digital payments, a framework for retail offline payments across the country has been proposed.” This announcement has its roots in a series of successful pilot studies. The results of these experiments strongly suggest that there is more leeway for digital payment-related solutions, particularly in rural areas. According to Nitin Mathur, CEO of Tavaga Advisory Services, “the RBI is enthusiastic about expanding the ease of doing business in India as well as more innovative fintech prospects to capitalize on” as a result of this development.
According to Livemint, the Indian Railway Catering and Tourism Corporation (IRCTC) has partnered with e-payment provider Paytm to provide ticketing services through Automatic Ticket Vending Machines at railway stations in order to make travel easier for commuters. According to reports, the service has already begun at all Automatic Ticket Vending Machines (ATVM) in Indian railway stations. Passengers will be able to pay for tickets using digital methods and commute fully cashless as a result of this.
Customers can make payments using Paytm Wallet, Paytm UPI, Net Banking, Debit Card, Credit Card, Net Banking, and Paytm Post-paid, among other methods (Buy Now, Pay Later).
The touchscreen ATVMs installed at train stations let passengers purchase tickets using UPI rather than a smart card. Passengers must scan the QR code displayed on the ATVM screen in order to access the service. After scanning, passengers can quickly purchase platform tickets, unreserved train journey tickets, recharge smart cards, and renew seasonal tickets.
“Firstly tested the QR code revolution in India, we are happy to carry it forward by offering the convenience of ticketing across railway stations,” a Paytm representative said. He went on to say that Paytm’s relationship with IRCTC will provide QR solutions to Indian Railways’ Automated Ticket Vending Machines. And, he noted, this will enable people to go totally cashless when purchasing tickets.
Follow the instructions below to utilize the ATVMs’ digital payment feature at train stations.
First, find an ATVM at your local train station.
Step 2: Using the touchscreen, choose a route for reserving a ticket or enter a smart number for recharging.
Step 3: Make your payment using any Paytm option.
To complete the transaction, scan the QR code generated on the screen.
Step 5: Depending on your choices, a physical ticket or a smart card recharge will be generated.
WhatsApp is focusing on improvements to its user interface. The chat application was recently caught developing a new profile cover photo that looks like it belongs on Facebook. Users can now add covers to their WhatsApp profiles, according to a new feature discovered recently. The functionality is intended for use by businesses. WhatsApp’s library is anticipated to benefit from the new capability.
WhatsApp users will soon be able to customise their profile covers, according to Wabetainfo. This feature, however, will be available only to WhatsApp Business accounts; normal user accounts would not be able to use it. According to the article, beta testers will be able to use the feature, and your business profile settings will be altered.
According to a screenshot obtained by Wabetainfo, WhatsApp intends to add a new camera button to your Business Settings. Like the cover photo, you can choose an existing photo or take a new one. Your cover photo will be visible to everyone visiting your business profile (including ordinary WhatsApp user accounts).
On WhatsApp on iOS beta, the feature was discovered to be in the testing phase. WhatsApp Business for Android will get the same feature as well. A release date for the feature is unknown because it is still in development.
Aside from that, WhatsApp has been seen developing a new voice call interface. Since December 2021, the messaging app is said to have been working on a new interface. The user interface for both the iOS and Android apps was previously built. However, for Android beta testers, WhatsApp has recently released a revamped calling experience.
WhatsApp is updating its caller interface not only for individual conversations but also for group calls.
When you make a group voice call, bring voice waveforms for all participants during the call, as seen in the screenshots. The new upgrade is being sent out to Android beta testers today, according to Wabetainfo, with more activations expected in the following weeks. The new UI has yet to be seen on the iOS beta app, but according to the features tracker, WhatsApp may receive it in a future release.
