Excellence is a continuous process and not an accident – APJ Abdul Kalam.
Our Former President APJ Abdul Kalam was among the great leaders India had and the world needs. Simplicity and Integrity defined him. Kalam loved interacting with students, his Birth anniversary is fondly marked as Student’s Day.
Kalam dreamt to be a fighter pilot in Indian Air Force but was merit out as only 8 slots were available and he secured the 9th position, he was shattered. He said in his book,“It is only when we are faced with failure do we realise that these resources were always there within us. We only need to find them and move on with our lives”. He didn’t make it to IAF, but this failure turned out quite well as we got a leader who was respected beyond political boundaries. He played a pivotal technical and political role in strengthening India’s position globally. He was a key member of the civilian space and military missile programme.
Avul Pakir Jainulabdeen Abdul Kalam was born on October 15, 1931, in a poor Tamil Muslim family in Rameswaram.
After completing his graduation from Madras Institute of Technology in 1960, he joined DRDO and worked as a scientist. Kalam was groomed by Vikram Sarabhai and Satish Dhawan, they were his mentors. In 1969, Kalam was transferred to ISRO where he was the project director of India’s first Satellite Launch Vehicle (SLV III) which successfully deployed the Rohini satellite orbit. He made an effort to develop the Polar Satellite Launch Vehicle (PSLV), which turned out to be successful.
In the 1970s, Kalam also directed two projects, Project Devil and Valiant, which sought to develop ballistic missiles from the technology of the successful SLV programme.
During the same period powerful countries amalgamate to prevent the spread of technologies and disarmament of other countries, signed treaties like Non-proliferation Treaty (NPT), Comprehensive Nuclear-Test-Ban Treaty(CTBT) and to combat these Missile Technology Control Regime(MCTR) India started its advance Indigenous missile programme.
He was the chief executive of this Integrated Guided Missile Programme which developed missiles like Prithvi, Trishul, Akash, Nag and technological demonstrator Agni. He is the brainchild behind India’s current ambitious missile programme.
Kalam believed in Made in India and to be strong India needs to design, develop and protect itself. He profusely said this programme was a step towards a self reliant India.
He led the weaponization of strategic Nuclear tests in Pokhran under the Bajpayee Government and made India a Nuclear weapon state. India’s nuclear era emerged on 11th May, 1988 also celebrated as National Technology Day.
He worked towards societal upliftment in the defence sector which led to a number of developments in the medical field. In 1998, along with cardiologist Soma Raju, Kalam developed a low cost coronary stent, named the “Kalam-Raju Stent”. He introduced the lightweight fro and calipers for polio affected, made of glass filled polypropylene reducing weight from 4kg to 400gms, this carbon composite material was the brainchild of Kalam when he was director at DRDL also used at the tip of Agni missile.
He served as 11th President of India from 2002 to 2007. He secured backing from all political parties, a people’s leader in true sense.
After his term ended he returned to a life of education and public service. He was served with many honorary degrees and awards including India’s highest civilian honour Bharat Ratna(1997), Padma Vibhushan(1990) and Padma Bhushan (1981).
He was a scientist and our beloved politician, he also liked to write poetry in Tamil, learnt playing Veena, listening to Carnatic music and writing books, including Wings of fire, Ignited minds, India: Vision 2020 and many more.
Kalam’s vision for development of our country was something he worked on till his last moments. He left us doing what he was most admired for – teaching. On 27th july, 2015 a magnificent presence was withdrawn, he collapsed while delivering a lecture in IIM Shillong, followed by an apparent cardiac arrest.
Scientists spot a sign of possible Life on Venus
VENUS- Earth’s evil twin it’s clouds are made of battery acids. At 900 degrees its surface heat enough to melt lead, Venus is pretty much like the biblical vision of hell today. This may be the hostile real estate in the solar system yet billions of years ago Venus looked alike Earth but to the near of sun Venus was doomed and Earth blossomed. Venus burned yet even here life may thrive.
An international team of astronomers has detected a rare molecule in the atmosphere of Venus that could be produced by living organisms. The discovery instantly puts the brightest planet in the night sky back into the conversation about where to search for extraterrestrial life.
The surface of Venus is a more like a hell. However, some layers of its clouds spot surprisingly hospitable temperatures and pressures. Phosphine is a poisonous gas however, the organizers of the study and other experts agree that the presence of phosphine is not proof of life on another planet.
As astronomers look for signs of life outside our solar system, one method is to look for chemicals that result only from biological processes. These processes are known as bio-signatures.
Phosphine can form only in two ways on Earth. It can be created by an industrial process, or it can come from a biological process in animals and microbes that is not well understood. Some scientists consider it as a waste product.
It’s said that phosphine can be found in the bottom of ponds, the insides of animals like badgers and in the waste of penguins. The astronomers carefully looked at all the possibilities for production of the phosphine: volcanoes, lightning strikes or meteorites falling into the atmosphere. Not a single process we looked at could produce phosphine in high enough quantities to explain the team’s findings.
Furthermore, it is noticed that 50 kilometers above the planet’s surface, in Venus’ thick carbon dioxide clouds, it is about room temperature. The clouds are mostly made up of sulfuric acid. But they also contain droplets with very small amounts of water.
The scientists asked themselves if the phosphine could be coming from microbes living inside the sulfuric acid droplets. Than when the droplets fall to the ground, they might dry out but could collect in other droplets and reanimate.
Venus is one of the most beautiful objects in Earth’s sky. But at a closer glance, the less lovely it becomes. Venus is roughly the same mass as Earth. Many scientists think that Venus was once covered in water and possessed an atmosphere where life as we know it could have flourished.
In earlier days of the solar system, Earth was not so hospitable to the desires we have. Even an entire biosphere that did not survive in the oxygen-rich environment that later developed. And much as Earth over time became a home for jellyfish, ferns, dinosaurs and Homo sapiens, Venus was transformed by something into a hell.
Today, the second planet from the sun has an atmosphere stifled by carbon dioxide gas, and surface temperatures that average more than 800 degrees Fahrenheit. The dense atmosphere of Venus exerts a pressure of more than 1,300 pounds per square inch on anything at the surface. That is more than 90 times the 14.7 pounds per square inch at sea level on Earth, or the equivalent to being 3,000 feet underwater in the ocean.
For the last two decades, scientists keep making new discoveries that collectively imply a significant increase of the likelihood to find life elsewhere. Many scientists would not have guessed that Venus would be a significant part of this discussion. But, just like an increasing number of planetary bodies, Venus is proving to be an exciting place of discovery.
If there really is phosphine on Venus, its believed there could be no other obvious explanation than anaerobic life.
Chandrayaan: A successful series
Chandrayaan as its name suggests the vehicle for the moon. All the series of Chandrayaan have been very successful and have been sending very valuable and unique pictures of the moon. The Chandrayaan-2 has completed one whole year on 7th September 2020. It has shown good progress up in the orbit of the moon. We have been trying to reach the moon and find out the valuable resources up there. An atmosphere like Earth, maybe we can create it there. Water was also found by the previous versions of Chandrayaan. Indian Space Research Organization (ISRO) has been trying to reach the south pole of the moon and find the water existence.
Talking about Chandrayaan-3 it will be launched in March 2021 and will be slightly different from its predecessor Chandrayaan-2. Chandrayaan-3 will not have an orbiter but it will only consist of a lander and a rover. Due to the Corona pandemic situation, there has been a delay in launching Chandrayaan-3. The target area will be the South Pole of the moon and the rocket used in this is the most powerful rocket of ISRO till date is the GSLV Mark 3. The launch site will at Satish Dhawan space center.
Moon is the closest we can explore. Moon may have some of the properties of the Earth because of the close distance. Chandrayaan-1 sent some images of rusting on the poles of the moon that show that there is the existence of water and oxygen because if these two elements are there then only the iron-rich rocks that are present there can react and rusting can happen. Because of the hard landing, Chandrayaan-2 ‘s Vikram lander had some problems but it is there in the lunar orbit and has enough fuel to survive till 7 long years. Chandrayaan-3 is a repeat mission of version 2 and it has an only lander and lunar rover and it is planned that this time there will be a soft landing. So hoping for the good and Chandrayaan-3 will be at its new heights soon.
Following this timeline Ministry also announced the first crewed orbiter namely Gaganyaan. This project will be launched in December 2021. An extent to 400km in the Earth’s orbit and the rocket used here is also GSLV mark 3. The maximum space for the crew is 3. Hope this would be a success.
Year of tech convergence 2020
Well, as far as the COVID-19 is concerned, it’s successful in completely destroying the year 2020. But, some inventions or concepts that might be successful in future can bring a smile on your face. So, after short listing we have come up with the list.
1. 5G connections.
5G can come up everywhere You may have already seen ads about 5G wireless phones. AT&T and Verizon both are setting up small connection points in public places, like sports stadiums, to show off what’s to come. But that’s just the tip of the iceberg. Right now, 5G doesn’t have a lot of range, which is why it can only be used in small areas, but that won’t always be the case.
According to Computer World, the 5G implementations out there right now use millimetre-wave technology, which uses the highest frequencies, but has the least range, which is why it can currently only cover portions of an NFL stadium, for example. This will change, however, as lower-frequency service is on the way, too, and while it won’t be as fast, it will have greater range, and still be way faster than 4G LTE, the current standard.
The most exciting thing about 5G, though, is that it’s not just for phones. 5G will be a full-on broadband internet service, meaning that instead of having one service for your mobile devices and one for home internet, you’ll be able to get home 5G and take it with you, as well. That also means less reliance on Wi-Fi and more potential for devices with their own, dedicated connection.
2. Electric car batteries.
Electric car batteries will only get better Electric cars are becoming more likely to replace standard cars every year, but currently, one of the biggest things holding them back are batteries. Your typical electric car today only has a range of 150 to 310 miles and takes an hour or more to charge. Once your vehicle runs out of juice, you might be stuck waiting for it to recharge.
But two new innovations are on the way. First, a new discovery has reduced those hours long charge times down to just 10 minutes. It works by increasing the temperature of the battery as it charges, which researchers have found causes the charging reaction to occur far more quickly than it did before. Best of all, this doesn’t degrade the battery at all, according to Science. The battery’s lifespan remains the same.
Meanwhile, Swiss company Innolith claims to have created a new electric car battery than can offer 600 miles on a charge, according to The Verge. That’s more than two tanks of gas for your average fossil fuel vehicle. It will take some time to release, and there are some skeptical folks out there, as independent researchers and reviewers haven’t gotten to take a look at the battery themselves just yet. Even still, the race to create a more efficient and higher capacity battery is ongoing now, and they’re only going to improve.
People will be able to feel things in virtual reality Virtual reality (VR) and augmented reality (AR) made a big splash in the last decade, but things will only get more interesting from here, starting with the ability to touch and feel the things we see through all the various kinds of computer-generated imagery. While experiments of this sort have been tried in the past, the results were often very bulky and required a ton of power, necessitating large batteries to be attached.
Now, though, new technologies are allowing for tactile “skins” that are far thinner and require far less power. One of these is developed by John A. Rogers and his team at North-western University. Their skin uses tiny, thin discs to create vibrations instead of bigger actuators you might find in a gaming controller or phone, which use a lot more power. What’s more, they’re thin enough they can be charged using near-field technology, meaning less reliance on large batteries, according to Scientific American.
Meanwhile, Swiss researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have developed their own tactile skin, which works similarly, but uses pneumatic actuators instead and can provide very delicate amounts of tactile feedback all the way up to one Newton of force. These aren’t the only two groups working on this, either, so it’s likely there will be hepatic feedback patches all the way up to clothing like gloves and, someday, entire suits of second skin.
