Why was Apple forced to switch to USB-C?

Shreyas Sen

Apple recently announced that it plans to adopt the USB-C connector for all four new iPhone 15 models, helping USB-C become the connector of choice of the electronics industry, nine years after its debut. The move puts Apple in compliance with European Union law requiring a single connector type for consumer devices.

USB-C is a small, versatile connector for mobile and portable devices like laptops, tablets and smartphones. It transfers data at high speeds. transmits video signals and delivers power to charge devices batteries. USB stands for Universal Serial Bus. The C refers to the third type, following types A and B.

The USB Implementers Forum, a consortium of over 1,000 companies that promote and support USB technology, developed the USB-C connector to replace the older USB connectors as well as other types of ports like HDMI, DisplayPort and VGA. The aim is to create a single, universal connector for a wide range of devices.

The key features and benefits of USB-C include a reversible connector that you can insert in either orientation. It also allows some cables to have the same connector on both ends for connecting between devices and connecting devices to chargers, unlike most earlier USB and Lightning cables.

USB-C’s widespread adoption in the electronics industry is likely to lead to a universal standard that reduces the need for multiple types of cables and adapters. Also, its slim and compact shape allows manufacturers to make thinner and lighter devices. USB-C refers to the physical connector. Connectors use a variety of data transfer protocols – sets of rules for formatting and handling data – such as the USB and Thunderbolt protocols.

The latest USB protocol, version 4, provides a data transfer rate of up to 40 gigabits per second, depending on the rating of the cable. The latest Thunderbolt, also on version 4, supports up to 40 gigabits-per-second data transfer and 100 watts charging. The newly announced Thunderbolt 5 will support up to 80 and 120 gigabits-per-second transfer and 140 to 240 watts power transfer over a USB-C connector.

Since its introduction in 2014, USB-C has gained widespread popularity and has already become the connector of choice for most non-Apple devices. Apple converted the iPad Pro to USB-C in 2018 and now is doing the same for the best selling Apple device, the iPhone.

Thanks to the industrywide adoption of USB-C, consumers soon won’t have to ask “Is this the right connector?” when they reach for a cable to charge or sync their portable devices. (This article is republished from The Conversation under a Creative Commons licence.)

What is the concept of the first british atomic bomb?

Like it or not, science and technology sees unprecedented growth during dire times. This is probably because funding flows into different branches of science like never before, allowing for progress inconceivable during ordinary times. Just like how the COVID-19 pandemic saw a global collective search for vaccines, there have been other times in the past – mostly during wars – when a number of scientific fields received a tremendous boost.

World War II was one such period when scientific progress was at its pinnacle. The ability to split an atom through nuclear fission was discovered in the 1930s. With its ability to release immense power realised, it wasn’t long before the race to build a bomb with it was on. The Manhattan Project was born early in the 1940s and we all know what happened in Japan’s Hiroshima and Nagasaki.

To retain influence                                           

While the Manhattan Project was led by the U.S., it was done in collaboration with the U.K. along with support from Canada. Following the war, however, the U.S. refused to share atomic information with the U.K. With the objective of avoiding complete dependence on the U.S., and to remain a great power and retain its influence, Britain sought to become a nuclear power.

The prospect was discussed in a secret cabinet committee in October 1946. While Chancellor of the Exchequer Hugh Dalton and President of the Board of Trade Stafford Cripps were opposed to the idea of a British bomb citing the huge costs involved, Secretary of State for Foreign Affairs Ernest Bevin had his way and work went ahead. By the time the bomb was ready, however, Winston Churchill’s government came to power.

Penney at the helm

Led by British mathematician William Penney, who had worked on the world’s first atomic bomb in the U.S., the project that went on to become Operation Hurricane began with a secret laboratory tasked with developing the trigger device. With the Soviets managing to successfully explode their first atomic bomb in 1949, Penney’s team was under further pressure. Soon enough, the Brits were ready with their bomb.

Early in 1951, the Australian government agreed that the blast could take place at the uninhabited Monte Bello islands, an archipelago of over 100 islands lying off the coast of north-western Australia. The region was declared a prohibited zone and ships and aircraft were later warned to stay clear of an area of 23,500 nautical square miles off the coast.

Plym carries the bomb

 The troops were mobilised, the first set of vessels left for their destination in January 1952 and six months later HMS Plym, carrying the bomb, and the fleet flagship HMS Campania, made their way. The radioactive core, which used British and Canadian plutonium, was flown out later, and installed in the bomb on Plym very close to the scheduled detonation.

On the morning of October 3, 1952, Britain’s first atomic bomb exploded, sending thousands of tonnes of rock, mud, and sea-water blasting into the air. The Plym was instantly vaporised, with scant bits of red-hot metal from the vessel falling on one of the islands even starting a fire.

An eye-witness account of a Reuters correspondent stationed less than 100 miles away mentions a grand flash followed by the appearance of a grey cloud-a zigzag Z-shaped cloud as opposed to the mushroom cloud that we instantly associate with such detonations.

The success of Operation Hurricane resulted in Penney being knighted. Churchill, who was serving as the Prime Minister of the U.K. for a second time, announced to the House of Commons that there had been no casualties and that everything had gone according to plan. While he did congratulate the Labour Party for their role in the whole project, he also did take a dig at them saying that ‘as an old parliamentarian I was rather astonished that something well over £100 million could be disbursed without Parliament being made aware of it.’

Why National Science Day is celebrated?

 

It is our fundamental duty to develop a scientific spirit, says our Constitution. It’s, perhaps, the only Constitution in the world to say that. No wonder then that India has a dedicated day to celebrate science – the National Science Day. It is celebrated on February 28, to mark the discovery of light scattering – or the Raman Effect – by Nobel laureate Indian physicist, Sir CV Raman.

Nearly a century has passed by since the Raman Effect was discovered, revolutionizing the study of Physics and our understanding of the world. During this period, despite all the challenges and intermittent derailment of efforts, India has upheld its commitment to science, thanks to the efforts of successive generations of policymakers.

We have overcome a multitude of challenges, since our Independence, through the deployment of scientific solutions. India’s scientific community saved the country from the brink of starvation and famines through the Green Revolution. Today, India is a leading exporter of several agricultural commodities.

It also saved India from multiple health disasters. Polio and smallpox were effectively eradicated. An AIDS epidemic was brought under control. Maternal and Infant Mortality Rates were brought down by our health experts who worked with rural and urban poor communities to raise awareness and adopt medical procedures. Even during Covid-19, India was among the first few countries to indigenously produce a vaccine to control the pandemic

From a time when Western media and leaders mocked our space-tech ambitions, India has risen to challenge the Western hegemony over the skies and beyond. From being a defence equipment importer, we are now looking to export our products to other countries.

All of this was made possible through the advancement of science. India and Indians have been at the forefront of the IT and digital revolution. Engineers and technocrats from India lead several global technology corporations today. This has been possible because of the large-scale adoption of STEM education by Indians across the country.

According to the World Economic Forum, amid a global short supply, it’s India that is producing the highest number of STEM graduates in the world, year after year. Nearly 35% of all our graduates passing out of colleges have specialized in STEM subjects. They are major contributors to the global economy.

Yet, not all is hunky-dory. The changing socio-political climate has watered down the scientific temperament of the collective society. India ranks at 40th place in the global innovation index, while countries much smaller than us rank higher. Singapore, for instance, is ranked fifth.

While the deep science ecosystem has witnessed significant growth in the country, the scientific tools for sustainable development are yet to reach the hands of frontline communities. Scientific approach to problem-solving in other fields, such as public administration, city planning, and urban development is also lacking.

In this National Science Day special issue, we look at some of these pertinent topics. How students can inculcate scientific temper. What major deep-tech innovations are disrupting the Indian startup market. How space junk is a growing menace. Is India spending enough on Research and Development… We will be discussing these points in this Issue.

This Issue also has a curated set of articles written by scientists, educators, and research scholars. On the fun side, we look at the real-life experiment that inspired Mary Shelly to write the incredibly popular Frankenstein, and the common tropes on robots in books and movies. We hope this Issue inspires and entertains you in equal measure.

What is the name of the smallest bear in the world?

The sun bear is the smallest bear species in the world. It gets its name from the yellow or creamy white mark on its chest that resembles the rising sun. It is also known as the Malayan bear.

Compared to the biggest bear species – the polar bear and the Kodiak or grizzly bear, which stand almost 3 metres (9.8 feet) tall and weigh around 635 kilos, the sun bear grows to about 1.2 metres (36 cm) in length and weighs around 40 kilos. It has a black coat and a light grey or orange nose. The feet are tipped with long sickle-shaped claws, which are sharper and curvier than in most other bear species. The soles are hairless.

Sun bears build nests in trees by breaking or bending the branches. They spend the day in the nests, sleeping and basking. They hunt only at night.

In 1978, the IUCN included the sun bear in its Red List of endangered species. Although its population has decreased due to hunting, a few thousand can still be found in the forests of the Malay Peninsula, Java, Sumatra, Myanmar, Borneo and Thailand.

Why are stonefish so poisonous?

Stonefish is perhaps one of the world’s best camouflaged fish. But it is also the most venomous. Found in shallow waters of the tropical Indo-Pacific, stonefish stay in the muddy or rocky bottoms of marine environments, living among rocks or coral. It may look like a stone on the ocean floor and deceptively stays blended with the ocean floor while hunting. The skin covered by wart-like lumps helps it in camouflage. It has venomous spines and when stepped on accidentally or there is a contact, it can sting. The sting is painful and can be fatal. Did you know that the fish is a delicacy in certain parts of Asia after its venomous spines are removed.

What is a venomous lizard native to parts of the US and Mexico?

Native to the USA and Mexico, the Gila monster is a small, venomous lizard that is known to spend more than 90% of its life below the ground. As such you may not encounter the Gila monsters in the wild but bites are known to occur at times. The venomous lizard is known to use its venom only for defensive purposes. A mild neurotoxin, the venom of the creature is produced in the lizards’ salivary glands. The saliva is toxic and is found to contain the hormone exendin-4 which could be used to treat type 2 diabetes. Although its venom is deadly, it also has potential medicinal use. While the lizard is strictly nocturnal, above-ground sightings of it are also seen during the day.
