  • Science and Technology in Independent India

    As India celebrates 75 years of Independence, we encapsulate some defining moments of the nation’s journey in the field of science and technology…

    Today, seventy-five years after India’s independence, the country is considered as one of the top five superpowers on the planet, with Indian scientists contributing enormously to facilitating the country’s rapid development and progress. While it was the Prime Minister Pandit Jawaharlal Nehru who initiated several reforms in higher education and set up pioneering science and technology institutions like TIFR, DRDO, BARC, IITs, DST… the policies of subsequent governments ensured that we continued to stay on the growth and development track. The present-day government under Prime Minister Shri Narendra Modi is giving significant emphasis to creation of an ‘Atmanirbhar Bharat’ focusing on creation of a strong indigenous R&D and manufacturing infrastructure across the country.

    On the eve on India’s ‘Amrit Mahotsav’, we look back in history at some of the major milestones achieved by the country in the area of science and technology:

    1945: Tata Institute of Fundamental Research (TIFR) – Dr. Homi Jehangir Bhabha asked Sir Dorabji Tata Trust for help and cooperation to begin nuclear research program in India. In 1945, Tata Institute of Fundamental Research (TIFR) was born, and thus started India’s journey in the world of nuclear energy development.

    1954: India’s first Atomic Establishment at Trombay – Under the leadership of Dr. Homi Bhabha, the Atomic Energy Establishment, Trombay (AEET) was established in 1954. Later, the institution was renamed as BARC in 1967 to help consolidate all research and technology activities. Today, BARC is India’s premier research and development facility in nuclear science and engineering, giving the country a strategic edge in nuclear power.

    1956: India’s first atomic reactor ‘Apsara’– This first nuclear reactor was designed by BARC and built with assistance from United Kingdom. Apsara is a light water swimming pool-type reactor with a maximum power output of one megawatt thermal (MWt), and it first went critical on August 4, 1956. The reactor is utilised for various experiments including neutron activation analysis, radiation damage studies, forensic research, neutron radiology, and shielding experiments.

    1958: Formation of Defence Research and Development Organisation – DRDO was formed in 1958 from the amalgamation of the then already functioning Technical Development Establishment (TEDs) of the Indian Army and the Directorate of Technical Development & Production (DTDP) with the Defence Science Organisation (DSO). It has a network of laboratories engaged in developing defence technologies covering various fields like aeronautics, armaments, electronics, land combat engineering, life science, materials, missiles and naval systems.

    1959: Launch of Television – Television was introduced in India on September 15, 1959 in Delhi, and the programs were broadcasted twice a week for an hour a day. Initially, the topics covered were community health, citizen’s duties and rights, and traffic and road sense, but in 1961 the broadcasts were expanded to include school educational television project. The first major expansion began in 1972, when a second television station was opened in Bombay, and it was followed by stations in Srinagar, Amritsar, Calcutta, Madras and Lucknow.

    1964: The first Indian jet trainer – The two seat intermediate jet trainer HAL HJT-16 Kiran (Ray of Light) were built by Hindustan Aeronautics Limited (HAL) on September 4, 1964. The jet called Kiran-I was powered by the Rolls Royce Viper Mk 11 delivered to the Indian Air Force in March 1968. Later the trainer jet was upgraded with hardpoints under each wing for weapon training and redesignated as the Kiran-IA.

    1969: Indian Space Research Organisation (ISRO) – Established in 1969, ISRO is India’s pioneer space exploration agency with a vision to develop and harness space technology in national development. Over the years, ISRO has gained place among the elite space agencies in the world owing to its unique and cost effective technologies. Recently, it conducted several remarkable space probes like Chandrayaan – 1 lunar orbiter, Mars Orbiter Mission (Mangalyaan – 1) and ASTROSAT space observatory.

    1974: Pokhran – India’s first successful nuclear bomb – After Indira Gandhi had authorised scientists at BARC to design nuclear device in September 1972, it took nearly two-years of preparation to conduct the first nuclear test. Code named ‘Smiling Buddha’ the test was conducted on May 18, 1974 in the deserts of Pokhran, Rajasthan. This made India the world’s sixth nuclear power country.

    1975: Launch of Aryabhata – Named after the ancient Indian astronomer – Aryabhata, the country launched its first satellite into space on April 19, 1975. The satellite was constructed by the Indian Space Research Organisation (ISRO) and was launched into space aboard a Kosmos-3M launch vehicle from Kapustin Yar, the then Soviet Union’s rocket launch and development site.

    1978: India’s first test-tube baby – On October 3, 1978, Ms. Bela Agrawal delivered India’s first test-tube baby under the medical care and supervision of Dr. Subhash Mukhopadhyay. The child later named ‘Durga’ was conceived via in-vitro fertilisation, and the event took place just 67 days after the world’s first test-tube baby – Marie Brown, was born.

    1982: Launch of India’s first satellite – Insat-1A was a multi-purpose satellite system designed to provide two high power TV broadcast and twelve telecommunications national coverage transponders, in addition to providing meteorological services. The Insat-1A was launched by a Delta 3910 launch vehicle on April 10, 1982 but was abandoned on September 6, 1983 when its attitude control propellant was exhausted.

    1983: Research base at the South Pole – The country established its first scientific base station in Antarctica named Dakshin Gangotri. The station was built in record time of eight weeks by an 81-member team, and was powered by solar energy. The base was used to conduct scientific tests on radio transmission, physical oceanography, chemical analyse of freshwater lakes in the areas, geomagnetism, geology and glaciology.

    1984: First Indian in Space – The Indian Air Force Squadron Leader Rakesh Sharma spent eight days aboard the Salyut 7 space station along with two Soviet Cosmonauts. They had departed on April 2, 1984 in a Soyuz T-11 spacecraft. This manned mission saw Sharma conduct several scientific and technical studies in the area of biomedicine, remote sensing and construction of hydro-electric power station in the Himalayas.

    1988: Launch of C-DAC – In 1987, when US President Ronald Reagan refused to sell their supercomputers CRAY, India decided to develop it indigenously. In 1988, the Centre for Development of Advanced Computing or C-DAC was launched under the leadership of Dr. Vijay Bhatkar. With a deadline of three years and a budget of around Rs. 30 crore, India’s first super computer PARAM 800 was developed in 1991.

    1991: DNA Finger Printing – During his study of evolution of sex chromosomes in a species of snake, Dr. Lalji Singh observed and recorded specific pattern in the DNA sequences, which he named the ‘Bkm sequences’. He made use of this technique to identify people based on specific characteristic of their DNA, and was able to solve several court cases over disputed paternity and criminal cases. He pioneered the concept of ‘DNA fingerprinting’ in India.

    1993: Launch of Pentium Chip – Vinod Dham is popularly known as the ‘Father of the Pentium Chip’ for his contribution to the development of highly successful Pentium processors from Intel. Responding to consumer’s demand of computers with faster processing speed, Intel changed the game with the launch of its breakthrough chip – the Pentium.

    1994: India’s first heart transplant surgery – On August 3, 1994 a team of 20 surgeons led by Dr. Panangipalli Venugopal performed India’s first successful human to human heart transplant at the All Indian Institute of Medical Sciences (AIIMS), New Delhi. The entire operation took nearly 59 minutes and the patient lived for at least 15 more years.

    1998: Pokhran – II – Operation Shakti stunned the world community as India conducted a series of five nuclear weapons tests – one fusion or thermonuclear weapon, two fission devices and two sub-kiloton devices, which proved to the world India’s capability in development of nuclear arsenal. Pokhran – II was the first Indian test of a nuclear weapon after 1974.

    2000: Launch of indigenous fighter jet – Tejas, the single seat, single-engine, lightweight, high-agility supersonic fighter aircraft made its first maiden test flight aboard Indian Navy’s aircraft carrier INS Vikramaditya in January 2000. The aircraft’s design and development program was led by Aeronautical Development Agency (ADA) under the supervision of Hindustan Aeronautical Limited (HAL).

    2002: The Simputer – A low cost alternative to conventional computers, the Simputer was a self-contained, open hardware Linux-based handheld computer. It was devised to bridge the digital divide, but it did not succeed in taking off. Launched in 2002, it was the brainchild of seven scientists from the Indian Institute of Science, and was led by Dr. Swami Manohar. While it did not succeed, it remains an important home-grown development in computer manufacturing.

    2003: Kalpana Chawla space disaster – Kalpana Chawla, was the first Indian-origin woman to go space on a 16-day mission aboard NASA space shuttle Columbia. On the morning of February 1, 2003, the space shuttle was to return to Earth. At the time of launch, a briefcase-sized piece of insulation had broken off and damaged the thermal protection system of the shuttle’s wing. On its entry into the Earth’s atmosphere, the hot gas caused the break-up of the wing and the shuttle leading into an explosion killing all seven astronauts on board.

    2008: Chandrayaan – 1 – The country’s first unmanned mission into space became a reality with Chandrayaan -1’s moon mission. The mission launched on October 22, 2008 from the Satish Dhawan Space Centre – Sriharikota, Andhra Pradesh, included a lunar orbiter and an impactor. The goals of the mission included high-resolution mapping of the moon’s surface; near infrared, low energy X-ray and high-energy X-ray spectra, and preparation of a three-dimensional atlas of regions of scientific interest.

    2009: INS Arihant – After five decades of hard work, on July 26, 2009 India formally launched its first indigenously designed and constructed ballistic missile submarine (SSBN) – the INS Arihant. Powered by ISROs nuclear reactor, the submarine is designed to span the ocean depths at high speed and launch ballistic missiles and nuclear weapons in the range of over 3,000 km.

    2013: Mangalyaan – On November 5, 2013 India’s Mars Orbiter Mission lifted off from Sriharikota powered by PSLV C-25. After spending about a month in orbit around the Earth, the spacecraft Mangalyaan began its journey unto Mars. Almost a month later, the spacecraft entered the Mars’ orbit, putting India in the elite club of five countries which have successfully sent missions to Mars. At a cost of Rs. 450 crore, it was the cheapest mission to Mars, and India had succeeded in the very first attempt.

    2017: ISRO tests its first cryogenic engine – ISRO successfully tested its indigenously developed Cryogenic Upper Stage (CUS) for GSLV MkIII on February 17, 2017. It was tested for a flight duration of 640 seconds at ISRO Propulsion Complex (IPRC) in Mahendragiri, this test was carried out after a similar successful test for 50 seconds on January 25, 2017. The test is a significant milestone as it is the last in series of engine before the first flight of GSLV MkIII.

    2019: Chandrayaan – 2 Moon mission – India made a failed attempt to make a soft landing on to the lunar surface, and missed out on the opportunity of being the fourth country to successfully land on the moon, after erstwhile USSR, US and China. While the spacecraft has successfully entered the lunar orbit, the lander Vikram missed the primary landing site and went for the second. Thereafter, the visuals went missing as it had a crash landing.

    While each of the above scientific events have contributed in transforming India into a global superpower, there have been some major scientific revolutions based on government policies that have also played a strategic role in taking the benefits of these developmental changes to the masses:

    The Green Revolution – Post-independence, India was going through its worst agriculture disaster owing to re-occurrence of famines as the country was witnessing wide spread poverty and hunger. In 1960, the government made a policy decision to initiate the ‘Green Revolution’ under the guidance of Dr. M.S. Swaminathan. The country resorted to the use of modern agricultural methods and technology – high yielding variety (HYV) seeds, tractors, irrigation facilities, pesticides and fertilisers. This Green Revolution led to increase in food production and resulted in India becoming one of the world’s biggest agricultural producers.

    The White Revolution – After the huge success of the Green Revolution, the Indian government initiated ‘Operation Flood’ also known as the ‘While Revolution’ aimed at increasing milk production. It helped create a nationwide milk grid linking producers to consumers by eliminating the middlemen. The mission was to make India self-dependent nation in milk production. Pioneered by Dr. Verghese Kurien the revolution was a huge success, making India one of the largest producers of milk in the world.

    The Yellow Revolution – It started in 1986- 87, to multiply the production of vegetable oils, especially mustard and sesame seeds. During the Yellow Revolution, nine oil hybrid seeds – peanuts, mustard, soyabeans, saffron, sesame, sunflower, niger, flaxseeds and castor seeds were planted. Within 10-years of the launch of the program, India’s oil production doubled from 12 million tons in 1986 to 24 million tons in 1997. The Yellow Revolution also offered farmers several support incentives associated to processing equipment, irrigation equipment, fertizers, pesticides, etc.

    The Blue Revolution – Also known as ‘Neel Kranti Mission’, the Blue Revolution was launched in the year 1985 with the objective of developing, managing and promoting fisheries so as to increase farmer’s income and sustain livelihood. This revolution tripled the production of fish in India – both island and marine sector by 2020, transformed the fish and aqua industry into a modern industry using technology and processes, increased income through development of innovative marketing platforms and also ensured food security in India. Dr. Arun Kishnan and Dr. Hirlal Chaudhuri are known as Father of ‘Blue Revolution’ in India.

    The Golden Revolution – The period between 1991-2003 is known as the period of India’s ‘Golden Revolution’, as the country saw a phenomenal rise in production of honey and horticulture products under the supervision of Nirpakh Tutej, who is considered to be the father of the ‘Golden Revolution’ in India. During this period India became the world leader in the production of a variety of fruits like coconut, mangoes, cashew nuts and the second largest producer of vegetables and fruits in the world

    Conclusion Since ancient times, Science and Technology have always been an integral part of India’s culture, and Indian intellectuals have pursued higher education vigorously and engaged relentlessly in development and innovation activities. While the government of India has played a key role in creating conducive environment, it is Indian scientists like Chandrasekhara Venkata Raman, Har Gobind Khorana, Subrahmanyan Chandrasekhar, Venkatraman, Shanti Swarup Bhatnagar, Homi Bhabha… who have made the country proud with their extraordinary vision and work. India has evolved from humble beginnings into being a ‘Global Superpower’ and is all set to play a leadership role in all spheres of science and technology..

  • ‘Hap-Pea’ Birthday Mendel @ 200

    Tribute to the Man who discovered the Laws of Heredity. He performed experiments on Peas which brought him fame and laid the foundation a new discipline of science known as modern day Genetics… Rightly described as the ‘Father of Genetics,’ this ‘Hap-Pea’ man, Gregor John Mandel’s Birth Bicentenary is celebrated world over….

     

     

    Early Days

     

     

    The genius, Gregor John Mendel, born on July 20, 1822 in a German-speaking family that lived and worked on the family farm for generations which is now in the Czech Republic. During his childhood, Mendel worked as a gardener and studied beekeeping.

     

     

    Mendel loved his family very much and was grateful to them. He had a special emotional relationship with his family, and especially with his mother, He addresses his parents as ‘Dearest Parents’ or ‘Beloved Parents’, and his mother and sister as ‘Dearest Mother, Dearest Sister’.

     

     

    Mendel became a priest and from 1868 the Abbot of the Augustinian Abbey in Brno, which supported Science and provided the necessary facilities to Mendel. He became a Monk in part because it enabled him to obtain free education. After becoming a Monk, Mendel spent most of his life in the Augustinian Abbey of St Thomas in Brno. It was in this Monastery, he conducted his crossbreeding experiments with Pea plants, through which he discovered the role of Dominant and Recessive genes. This discovery later formed the core of Genetics, one of the most important sciences of the 20th century.

     

     

    Pea Experiments

     

     

    Mendel conducted very simple hybridisation experiments on over 5000 Pea plants which he had planted in the garden of his monastery at Brno. When Mendel planned his experiments with peas, he first studied the conclusions of his predecessors, who had undertaken similar experiments with plant crosses. He was aware that this would be a difficult task. He studied seven different characteristics of Pea Plants, including Height, Pod shape and Seed colour. Mendel showed that when two differently coloured Pea plants were cross-bred, their offspring always produced seeds of only one colour, but in the next generation he observed that the other colour reappeared in the ratio of one to three. Mendel coined the terms ‘Dominant’ and ‘Recessive’ for the different traits he observed in Pea plants. During ten years of experimentation on Peas, Mendel grew over 28,000 Pea plants and made conclusions on the different ratios he obtained that are now known as Mendel’s laws of heredity.

     

     

     

     

    The Genius

     

     

    Gregor Mendel (1822–1884) is regarded as the father of Genetics owing to his meticulous research on the common garden Pea (Pisum sativum) that allowed him to deduce fundamental laws of inheritance. His discovery of the laws of genetics were far ahead of his times. His insights were developed long before we understood the structure of DNA and the genes that constitute Mendel’s inheritance “factors.”

     

     

    The genius of Mendel’s contribution to science revelled the secrets of evolution. The two greats, Mendel and Darwin never met, but the theories proposed by Mendel proved to be complementary to the theory of evolution. Mendel’s work is not merely restricted in helping reveal the evolutionary mechanisms but his multidisciplinary approach is fascinating. Mendel achieved an unprecedented interconnection between theory and practice by using methods unknown to biological science of that time. He was one of the first to apply mathematical methods to biological research. His painstaking analyses of seven carefully selected traits assessed in approximately 28,000 Pea plants over the course of a decade allowed him to discover the fundamental laws of inheritance .

     

     

    Mendel published his work describing the actions of invisible ‘factors’ in determining the traits of an organism, these factors are now known as ‘genes’.

     

     

    Late Recognition

     

     

    When Mendel presented the results of his experiments in 1865, he received a little response. The world, which was overwhelmed by Darwin’s theory of evolution, did not understand Mendel’s work and its significance. The significance of Mendel’s work was not recognised until more than three decades later, with the rediscovery of his laws of inheritance Mendel gained posthumous recognition as the founder of science of Genetics. Mendel’s Pea plant experiments, conducted between 1856 and 1863, established many of the rules of heredity, now referred to as the laws of Mendelian Genetics. Mendel’s importance was rediscovered 16 years after his death, when his conclusions were confirmed by Erich von Tschermak, Hugo de Vries and Carl Correns while independently verifying Mendel’s experimental findings in 1900. This heralded a new era in modern age of genetics which earned him the title of “father of genetics”.

     

     

    Versatile Genius

     

     

    Gregor Johann Mendel A modest genius was an extraordinary versatile personality. He was a biologist, meteorologist and a mathematician too,

     

     

    Mendel enjoyed beekeeping since his very childhood. He invented new ways of overwintering of bees and he also tried the cross-bedding of bees. He was an outstanding pomologist. He cultivated vines and new species of fruit trees and regularly participated in competitions.

     

     

    Mendel was also fond of Meteorology. He was one of the Pioneers of Weather forecasting. Mendel made daily meteorological observations three times a day, at various sites of the Monastery, he carried out measurements for the Meteorological Institute in Vienna and kept the records of them.

     

     

    Mendel was also an excellent teacher. He taught Physics at a Secondary School in Brno, where he presented the results of his observations on inheritance in 1865. Mendel also wrote poetry and in one of his poems titled ‘The Man’ his life credo is described that ‘It is man’s destiny to strive for high goals and to use all his abilities to achieve them’.

     

     

    The great genius, the ‘Pea Man’ died on 6th Jan 1884, revealing the Laws of Heredity and giving birth to the Science of Genetics.

  • Temples of Modern India – Bhabha Atomic Research Centre

    “Research reactors are the backbone of the Nuclear Programme…” – Dr. Homi J. Bhabha

    Located in the hustling-bustling city of Mumbai, the Bhabha Atomic Research Centre (BARC) is the country’s leading nuclear research facility initiated by Dr. Homi Jehangir Bhabha. The centre’s huge infrastructure is a perfect platform for R&D (research and development) offering an entire gamut of nuclear science, engineering and related areas….

    BARC’s ideology is to use nuclear energy, basically for generation of power. The centre accomplishes all facts of nuclear power generation, from theoretical design of reactors to computerised modelling and simulation, risk analysis, development and testing of new reactor fuel materials to name a few. BARC also does research in spent fuel processing, and safe disposal of nuclear waste. Other research areas for BARC are applications for isotopes in industries, medicine, agriculture, etc. The centre also operates a number of reactors across India.

    Creation of BARC

    It was on 3 January1954 that the Government of India created the Atomic Energy Establishment, Trombay (AEET). The idea behind creating AEET was to unite all the R&D activity for nuclear reactors and technology under the Atomic Energy Commission (AEC). All scientists and engineers who were involved in various areas of reactor designing and development, instrumentation, metallurgy and material science etc., were transferred with their respective programmes from the Tata Institute of Fundamental Research (TIFR) to AEET; with TIFR retaining its original focus for fundamental research in the sciences. After Dr. Homi Jehangir Bhabha’s death in 1966, the centre was renamed as the Bhabha Atomic Research Centre on 22 January 1967.

    Mega Research Hub

    At the Gamma Gardens, BARC conducts research in biotechnology, and has developed a number of disease resistant and high-yielding crop varieties, especially groundnuts. It also conducts research in Liquid Metal Magnetohydrodynamics for power generation.

    On 4 June 2005, the centre started the Homi Bhabha National Institute with the goal of encouraging research in basic sciences. Research institutions affiliated to BARC include IGCAR (Indira Gandhi Centre for Atomic Research), RRCAT (Raja Ramanna Centre for Advanced Technology), and VECC (Variable Energy Cyclotron Centre). Power projects that have benefited from BARC expertise but which fall under the NPCIL (Nuclear Power Corporation of India Ltd) are KAPP (Kakrapar Atomic Power Project), RAPP (Rajasthan Atomic Power Project), and TAPP (Tarapur Atomic Power Project).

    The Bhabha Atomic Research Centre in addition to its nuclear research ideology also conducts research in other state-of-the-art technology areas like accelerators, micro electron beams, materials design, supercomputers, and computer vision etc. BARC has designed and developed for its own use a series of supercomputers – ‘Anupam’ using latest technology.

  • Smiling Buddha – India’s first Nuclear Test

    After the war against Pakistan in 1971, the then Prime Minister, Indira Gandhi who was touring the Bhabha Atomic Research Centre (BARC) in September of 1972 approved of a nuclear test. Without any hesitation, Physicist Raja Ramanna and chief of BARC at that time, took a team of around 75 scientists to design and build the plutonium implosion device. The test was kept as secret as possible and all the work on the project was carried under great secrecy…

    Successful test

    The Indian Army was given the work to dig a test shaft of about 330 feet underground at the Pokhran test site, Rajasthan. On May 18, 1974, the 1360 kilograms device exploded with a force equivalent to 8 kilotons of TNT. Immediately after the test was conducted, Ramanna reportedly informed Indira Gandhi of the successful test through a coded message: “The Buddha is smiling.” Although officially known as Pokhran I, the 1974 test was informally named ‘Smiling Buddha.’ A number of countries condemned India’s nuclear test. While Canada pulled its support for the Indian nuclear program shortly afterwards; United States considered the test a violation of the Atoms for Peace program and responded with sanctions against India.

    Superpower

    After its successful nuclear test of 1974, India took more than 20 years to build a nuclear arsenal and delivery system capable of military deployment. In the years after Smiling Buddha, India had significant difficulty procuring nuclear materials after international market refused to support its stand. Despite these challenges, the BARC leadership managed to construct their biggest nuclear plant to date—the Dhruva reactor at Trombay in 1977, which would produce most of the plutonium for India’s nuclear weapons program. The Indian government also approved a ballistic missile program in 1983. Over the next decade, the Defense Research and Development Laboratory (DRDL) built the short-range Prithvi missile and the long-range Agni missile. Both were eventually equipped with nuclear warheads.

    Operation Shakti also known as Pokhran II took place on May 11, 1998. India tested five nuclear devices, although not all of them detonated. Indian officials claimed that the bombs had a yield equivalent to 45 kilotons of TNT, but independent estimates put the number closer to 16 kilotons. “India is now a nuclear weapons state,” declared Prime Minister Vajpayee days after the tests, adding that “we have the capability of making big bombs for peaceful purpose.”

  • The Genius : Albert Einstein

    Albert Einstein is known as the greatest genius, mathematician and physicist. But how many of you know that as a toddler, he struggled with speech and needed therapy for the same? Taking you through some interesting episodes from the life of the genius scientist…

    Making of a Prodigy

    When Albert was four, his mother learnt that he was gifted with the understanding of mechanics. She introduced him to the world of music that helped him broaden his mind. When Einstein was 10 years old, he started educating himself under the guidance of his uncle Jakob Einstein, who bought the boy books for his school years much in advance. This way Albert managed to read them before the classes started and get good grades without active participation in classroom sessions. By the age of 12, much to his mother’s wonder, he was considered to be a Maths and Science prodigy and before he was 15 he had mastered differential and integral calculus.

    From a Clerk to a Professor

    Though Einstein was good in his academics,
his rebellious personality and bunking
classes, made his professors give him low recommendations for his graduation. He spent two years searching for an academic position
but had to settle for the job of a clerk at the
Swiss patent office in Bern. But this job gave
him enough of time for writing and conducting research. In 1905, he published four revolutionary articles that introduced his famous equation E=mc2 and the theory of special relativity. Despite this distinction, he got a full professorship job only in 1909.

    Genius of Albert Einstein

    In 1915, Einstein published his theory of general relativity, which stated that gravitational fields cause distortions in the fabric of space and time. But it remained controversial until May 1919, when a total solar eclipse provided the proper conditions to test its claim that a supermassive object—in this case the sun would cause a measurable curve in the starlight passing by it. English astronomer Arthur Eddington journeyed to the coast of West Africa and photographed
the eclipse, to confirm that the sun’s gravity had deflected the light by roughly 1.7 arc-seconds, exactly as predicted by general relativity. The news made Einstein an overnight celebrity.

    The Genius Brain for Research

    Einstein died in April 1955 from an abdominal aortic aneurysm. After his death, pathologist Thomas Harvey removed his famous brain during his autopsy and kept it aside for research. Harvey had the brain cut into pieces and sent to various scientists for research. Though a handful of studies were done, most have either been dismissed or discredited. The only one study that became famous was done by a team from a Canadian university which published a controversial paper in 1999 claiming Einstein possessed unusual folds on his parietal lobe – a part of the brain associated with mathematical and spatial ability.

    HOW TO MAKE GELATIN BIOPLASTIC?

    Plastic has been a cause for massive global pollution issues. But what if we mix science and some food technology to address the environment concerns with Bioplastic? Let’s explore this with a fun experiment….

    So, what do we need?

    Stove, Pot, spoon, whisk, three gelatine packets, water, food colouring.

    How do we make plastic from gelatine? 

    Add 3 gelatine to 75 ml of water in a pot. Add 2-3 drops of food colouring (optional). Whisk it well over medium low heat until completely mixed. Once the mixture begins to steam, it thickens a bit. At this point, remove it from the heat. Using a spoon, gently scrape off the foamy layer. This will reduce the cloudiness from the plastic formed. Now you get a clear liquid. Pour the formed solution onto a container lid and leave it to cool for about 45 minutes. After cooling, it will have a rubbery consistency material. It can be cut into different shapes and dried for about 2 days to form a hard plastic shape.

    What is the science behind the gelatine plastic?

    This plastic that we have created with gelatine is a form of bioplastic. Basically, gelatine is created by breaking down collagen, which is a long chain of amino acids – the building blocks of proteins. At room temperature, gelatine is solid, but when it is heated, the bonds between the chains loosen, thus allowing them to stretch. Thus when a mixture of gelatine and water is heated, the chains weeken. As it cools down, it traps the water molecules. This gives us a hard plastic instead of a jelly material.
