Samsung Electronics Co on Thursday introduced the world’s highest-resolution image sensor, with 64 megapixels for smartphones, to meet the growing demand for mobile devices with better image quality.
Samsung unveiled two new 0.8-micrometer pixel image sensors — the 64-megapixel ISOCELL Bright GW1 and the 48-megapixel ISOCELL Bright GM2, expanding its 0.8-micrometer pixel image sensor lineup, the smallest pixel size currently available in the market.
The world’s biggest smartphone vendor has focused on improving camera function across its range of smartphones, as more people consider picture quality to be one of the most important features when buying new devices, Yonhap news agency reported.
“Over the past few years, mobile phone cameras have become the main instrument for recording and sharing our everyday moments,” Park Yong-in, executive vice president of sensor business at Samsung Electronics, said.
“With more pixels and advanced pixel technologies, Samsung ISOCELL Bright GW1 and GM2 will bring a new level of photography to today’s sleekest mobile devices.”
The two image sensors are currently sampling and are expected to go into mass production in the second half of this year, Samsung said.
Samsung said it will accelerate technology development in image sensors for smartphone cameras to grab a bigger share of the growing market.
“The image sensor market is expected to grow to a level comparable to the current memory chip market through 2030 in line with advancements in artificial intelligence and 5G technologies,” Park told reporters.
The company said it has been also developing various sensors for automotive cameras to meet growing demands for self-driving cars.
“Vehicle components are the next market for image sensors,” Kwon Jin-hyun, vice president of Samsung’s System LSI sensor marketing, said. “We have been preparing various sensors for cameras used in cars, ranging from a parking assistant system to autonomous driving. Negotiations have been already been under way with some clients.”
Samsung has been actively promoting its system semiconductor products after announcing a 133 trillion-won ($115.7 billion) investment plan through 2030 to expand its non-memory chip and foundry business.
Image sensor shipments by Japan’s Sony accounted for 26.1 percent of the global market last year, trailed by Samsung’s 23.2 per cent, according to Japanese research firm Techno System Research. (IANS)
Diwali is arguably one of the most auspicious and celebrated holidays in South Asia. It is celebrated over the span of five days, where the third is considered most important and known as Diwali. During Diwali people come together to light, lamps, and diyas, savour sweet delicacies and pray to the lord. The day has various origin stories with the main them being the victory of good over evil. While the North celebrates the return of Lord Rama and Devi Sita to Ayodhya, the South rejoices in the victory of Lord Krishna and his consort Satyabhama over evil Narakasura.
Narakasura- The great mythical demon King
Naraka or Narakasur was the son of Bhudevi (Goddess Earth) and fathered either by the Varaha incarnation of Vishnu or Hiranyaksha. He grew to be a powerful demon king and became the legendary progenitor of all three dynasties of Pragjyotisha-Kamarupa, and the founding ruler of the legendary Bhauma dynasty of Pragjyotisha.

Narakasura was created, grew up to be strong and powerful but he was not satisfied with it, so he decided that he would worship Lord Brahma. He performed severe penance and was driven by the power of his penance; Lord Brahma appeared before him. Narakasura knew his mother loved him dearly so he asked Lord Brahma to grant him a boon that he would only die by the hands of his mother, Bhumidevi. Lord Brahma smile and ultimately granted him the boon.
Narakasura burst out laughing as Lord Brahma vanished. He thought no mother would kill their child so Lord Brahma had made him immortal. Drunk and maddened by his own power Narakasura brought all the kingdoms under his control and targeted Swargalok (Heaven). Even Indra (King of Gods) and demi-gods had to retreat in front of Narakasura. He kidnapped and took 16,000 women from the palaces as prisoners. Troubled by Naraksura's deeds the gods rushed to Lord Vishnu for a solution.
Lord Krishna and Devi Satyabhama were born to kill Narakasura
Lord Vishnu was born as Lord Krishna and Narakasura's mother Bhumidevi took the avatar of Krishna's wife Satyabhama. As Satyabhama, Bhumidevi was unaware of the knowledge of Naraksura being her son. Aditi the mother of all gods approached Satyabhama crying for help with bloodied ears as Narakasura had torn off the glowing earrings from the ears of Aditi.
Satyabhama was furious on gaining the knowledge of Narakasura's atrocities she asked Krishna to fight the demon king while she fights alongside him. Krishna agreed and they attacked the great fortress of Narakasura, riding his mount Garuda with his wife Satyabhama.
The furious battle unleashed. Krishna defeated Narakasura's general Mura and came to be known as Murari (the killer of Mura). Narakasura used several divine weapons against Krishna, but Krishna slew all those weapons effortlessly. The demon hurled a shakti towards Krishna, which mildly hurt Krishna and he fell unconscious. Upon this sight Satyabhama was enraged, she furiously pulled out a weapon of her own and hurled it at Narakasura's chest. Anxious Satyabhama turned to her fallen Lord, Krishna got up with a smile and he was completely fine. He was only playing his part. It was Satyabhama who was an incarnation of Bhoomidevi, whose hands were destined to slay Narakasura.

Lord Krishna and Goddess Satyabhama had put an end to the Narakasura's kingdom of evil. As Narakasura lay on his deathbed he realised that Satyabhama was no one but an avatar of his own mother. He requested a boon from his mother, for no one to mourn his death. Instead, he wished for people to celebrate it with light and colours. They freed the 16,000 women who later married Lord Krishna to restore them of their honour in society, retrieved Mother goddess's earrings. This day is celebrated as 'Naraka Chaturdashi' popularly known as Choti Diwali - the day before Diwali as the triumph of good over evil.

For all the great inventions that we have at hand, it is amazing how we keep going back to the safety pin every single time to fix everything. Be it tears in our clothes, to fix our broken things, to clean our teeth and nails when toothpicks are unavailable, to accessorize our clothes, and of course, as an integral part of the Indian saree. Safety pins are a must-have in our homes. But how did they come about at all?
The safety pin was invented at a time when brooches existed. They were used by the Greeks and Romans quite extensively. A man named Walter Hunt picked up a piece of brass and coiled it into the safety pin we know today. He did it just to pay off his debt. He even sold the patent rights of this seemingly insignificant invention just so that his debtors would leave him alone.

Later, he even invented the sewing needles and a couple of other important inventions but never kept any of the patent rights.
When the punk rock tradition took over in the seventies, safety pins became a fashion rage. They were used as piercings and to patch clothes together. Anyone wearing safety pins that were visible began to be associated with the rock movement. In some cultures, the safety pins have become symbols of good luck.

In South India, Deepavali marks the end of the monsoon and heralds the start of winter. The festival is usually observed in the weeks following heavy rain, and just before the first cold spell in the peninsula. The light and laughter that comes with the almost week-long celebration are certainly warm to the bones, but there is still a tradition that the South Indians follow to ease their transition from humidity to the cold.
Just before the main festival, the family bathes in sesame oil. This tradition is called 'yellu yennai snaana' in Kannada, or 'ennai kuliyal' in Tamil, which translates to 'sesame oil bath'. The eldest member of the family applies three drops of heated oil on each member's head. They must massage this oil into their hair and body. The oil is allowed to soak in for a while, anywhere between twenty minutes to an hour. After this, they must wash with warm water before sunrise.

In some parts of the peninsula, soap is not used to wash off the oil because it nullifies its effects. Some cultures who do not like the oil to remain in any way on their skin wash it off with shikakai and herbs, which is a paste that is traditionally used as a substitute for soap. Sometimes, the oil is heated with flowers and spices as well and is less sticky than in its pure form.
The purpose of this ritual is to cleanse the body, detoxify it, and produce heat in it. Sesame is a very heaty substance and tends to heat up the body. This heat, or 'usshna' in Kannada, prepares the body to face the sudden cold that comes to the peninsula immediately after Diwali. South India has no smooth transition weather-wise from monsoon to winter. There are a few days of stable, rainless weather, and suddenly the cold winds descend.
In many ways, the celebration of Diwali is centered around preparing for winter, considering the amount of heat and light the rituals consist of – lighting lamps, bursting crackers, and consuming warm treats. Those who practice these rituals earnestly find the shift in seasons and weather quite pleasant.
