World Without Air

Image
World without air Human beings need air, water and food for existence. A man can live without food for a few days and without water for a few hours. But he may not be able to live without air even for a moment. It is because air consists of gases, chief among which are oxygen, nitrogen and carbon dioxide . Carbon dioxide is a toxic gas and is there in air in a very small quantity. It is essential for the life and growth of plants. Nitrogen which is the most abundant gas in air is a neutral gas. Oxygen is next only to nitrogen in amount in the air. It is  Hence, if there were no air, it means automatically that there would be no oxygen in atmosphere, if any, even which normally is unimaginable without air. If oxygen were not there, there would be no living beings. The earth would be just a dead mass of rock, sand, etc. There would be no oxygenation and perhaps nothing would either live, rejuvenate or degenerate  .  No life-human, animal or plant life – is possible without ...

Albert Eintein

Albert Einstein Albert Einstein  ( 14 March 1879 – 18 April 1955) was born in  German , widely acknowledged to be one of the greatest physicists of all time. Einstein is known for developing the  theory of relativity , but he also made important contributions to the development of the theory of  quantum mechanics . Relativity and quantum mechanics are together the two pillars of  modern physics . His  mass–energy equivalence  formula  E  =  mc 2 , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the  philosophy of science .He received the 1921  Nobel Prize in Physics  "for his services to theoretical physics, and especially for his discovery of the law of the  photoelectric effect ", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" be...

Artificial Inteteligence

  WHAT IS AI? From SIRI to self-driving cars, artificial intelligence (AI) is progressing rapidly. While science fiction often portrays AI as robots with human-like characteristics, AI can encompass anything from Google’s search algorithms to IBM’s Watson to autonomous weapons. Artificial intelligence today is properly known as , in that it is designed to perform a narrow task (e.g. only facial recognition or only internet searches or only driving a car). However, the long-term goal of many researchers is to create  general AI . While narrow AI may outperform humans at whatever its specific task is, like playing chess or solving equations, AGI would outperform humans at nearly every cognitive task. WHY RESEARCH AI SAFETY? In the near term, the goal of keeping AI’s impact on society beneficial motivates research in many areas, from economics and law to technical topics such as verification, validity, security and control. Wherea...

Role of Iot in health care

Image
Before Internet of Things, patients’ interactions with doctors were limited to visits, and tele and text communications. There was no way doctors or hospitals could monitor patients’ health continuously and make recommendations accordingly. Internet of Things (IoT)-enabled devices have made remote monitoring in the healthcare sector possible, unleashing the potential to keep patients safe and healthy, and empowering physicians to deliver superlative care. It has also increased patient engagement and satisfaction as interactions with doctors have become easier and more efficient. Furthermore, remote monitoring of patient’s health helps in reducing the length of hospital stay and prevents re-admissions. IoT also has a major impact on reducing healthcare costs significantly and improving treatment outcomes. IoT is undoubtedly transforming the healthcare industry by redefining the space of devices and people interaction in delivering healthcare solutions. IoT has applications in healthcare...
