Satyendra Nath Bose was an Indian physicist born in 1894 who made seminal contributions to quantum mechanics and statistics in the 1920s. He developed Bose-Einstein statistics, which showed that indistinguishable particles like photons should be described by a completely symmetric distribution, rather than the classical Maxwell-Boltzmann distribution. This laid the foundation for Bose-Einstein condensation. Bose sent his theory to Einstein, who recognized its significance, had it published, and extended Bose's ideas to predict the existence of Bose-Einstein condensates, which were later observed experimentally. Though his work was hugely influential, Bose himself did not receive a Nobel Prize.jagdish chandra bose

Sir Jagadish Chandra Bose was born in 1858 in British India and studied natural sciences at universities in India and England. Despite facing obstacles like lack of funding and research facilities, he made groundbreaking discoveries in the fields of radio and microwave optics, semiconductor research, and plant physiology. He invented devices like the crescograph to record plant responses and demonstrated that plants can exhibit electrical responses, similar to humans. Bose received prestigious honors over his career including election as a Fellow of the Royal Society and being knighted. He is considered a pioneer in scientific research.Indias contribution to the world

India contributed greatly to many areas including mathematics, science, philosophy, and medicine. Key contributions include developing the number system including zero, inventing algebra and trigonometry, calculating the time taken for earth to orbit the sun, establishing some of the earliest universities and institutions of advanced education like Takshashila and Nalanda, and establishing some of the earliest systems of medicine including Ayurveda. India was also a leader in many areas of science and technology throughout ancient times.Resource Centers for Educational Technology - CIET,SIET, AVRC, EMRC, SITE, CE...

2) Brahmagupta established the rules of operations for zero, including that adding or subtracting zero leaves a quantity unchanged and dividing by zero is undefined.
3) Nagarjuna discovered the process of alloying metals in the 2nd century BC and documented extraction and purification processes.contributions Issac Newton final ppt (1).pptx

Aryabhata was a mathematician and astronomer born in 476 AD in Kusumpur, India. He made several important contributions to mathematics and astronomy. He stated that pi is irrational, discussed sine and the circumference to diameter ratio of 3.1416. He also gave formulas for areas of basic shapes like triangles and circles. Aryabhata formulated early algebraic formulas and the first formula for interest and time in India. He did considerable work on astronomy as well, calculating the Earth's rotation and predicting eclipses.developmental task and hazards.pptx

This document discusses developmental tasks and hazards. It defines developmental tasks as tasks that must be successfully completed at different life stages in order to adjust to society. Failure can lead to unhappiness and difficulty with later tasks. Teachers should provide learning opportunities and motivation to help students succeed. Developmental tasks are outlined for pre-school, primary school, and secondary school age groups. Developmental hazards are factors that can alter fetal development, such as drugs, alcohol, tobacco, disease, and pollution. The prenatal environment can be negatively impacted by a mother's substance use or medication intake during pregnancy. Individual, family, and community risk factors in underdeveloped countries can also pose developmental hazards to children.Presentation on einstein

Albert Einstein was born in Ulm, Germany in 1879. As a child, he was fascinated by a compass and wanted to understand the invisible forces that guided it. In 1905, while working as a patent clerk in Germany, Einstein developed his Special Theory of Relativity and introduced the world to the idea that light exists as particles called photons. He went on to publish additional groundbreaking papers that year, including his famous equation E=mc2. Einstein later completed his General Theory of Relativity in 1915, which revolutionized the scientific understanding of gravity. He died in 1955 in Princeton, New Jersey at the age of 76, leaving behind a transformed scientific world.Sir C.V. Raman Biography

2. In 1928, Raman and Krishnan were studying the scattering of light in liquids and observed a "new type of secondary radiation" where the scattered light had a different wavelength than the incident light, indicating a change in the molecule's vibration/rotation.
3. On February 28th, 1928, Raman viewed the scattered light through a spectroscope and discovered that it contained not only the incident wavelength but another one separated by a dark space, proving thatbiology ppt by sagnik banerjee, k.v.s birbhum class 9

Subhash Chandra Bose was an influential Indian independence activist who founded the Indian National Army to fight against British rule in India. He served as the president of the Indian National Congress twice but later broke away to form his own party. During World War II, Bose sought help from Nazi Germany and Imperial Japan to liberate India and formed the Azad Hind Fauj, recruiting Indian soldiers from prisoner-of-war camps. While it is believed that Bose died in a plane crash in 1945, some believe he may have survived and disappeared. Overall, Bose made significant contributions to the Indian independence movement through his militant approach and establishment of the Indian National Army.A biologist in e-Science

90 10 principleRanjan Ghosh

The 90/10 Principle states that 10% of life is made up of external events outside of our control, while 90% is determined by our internal reactions to what happens. How we react to situations, both positive and negative, has a significant impact on our experiences and outcomes. While we cannot control what happens to us, we can control how we respond. Applying this principle means not letting uncontrolled external events ruin our day and instead focusing on handling situations with composure and optimism. This allows us to avoid unnecessary stress and conflict so that minor issues do not spiral out of control and negatively impact other areas of our lives.Teacher motivation

The Hindu system of time reckoning uses large units of time like yugas and mahayugas that last for thousands of years, rather than days, weeks and months. A mahayuga lasts for 4,320,000 years and is divided into four yugas of different lengths: Satya Yuga, Treta Yuga, Dvapara Yuga and Kali Yuga. The document provides details on the durations of each yuga and how they form a repeating cycle within the mahayuga. It also notes that the current yuga is Kali Yuga, which began over 5,000 years ago, and attributes the source and copyright for the information to radhasyam brahmachari.Jagadish Chandra Bose

He was a versatile genious a physicist, a botanist, biologist, an archaeologist and also an amazing writer of science fiction. Born in Rarikhal in Bangladesh, Bangladesh, in 1858, he started his studies first in Hare school, then St. Xaviers school and St. Xaviers college. Later he went to London university for study in medicine and he studied natural science in Christs college, Cambridge; University of Cambridge. He became the professor of physics at Presidency college, Kolkata. He is crowned as the inventor of first wireless detection device and for his pioneering research in discovery of millimeters and microwaves. Bose developed iron-mercury-iron coherer with telephone detector through Royal Society of London. He measured wavelengths, developed Galena detector, dielectric lenses, semiconductors of very high frequency (60GHZ transmission system). He kept his bold steps also in development of receiver, demonstration of propagation, refraction, polarization, photoelectric effect and effect of millimeter waves in biology. He was a biophysicist also and founded Bose institute in 1917 which was probably the 1st modern research institute in India. He was famous for his discussion in plant physiology (photosynthesis).
