Dr APJ Abdul kalam real life Story (By sandeep maheshwari) Hindi Best Mo...

Dr APJ Abdul Kalam –The Man Who Taught Us to Be Human First

Avul Pakir Jainulabdeen Abdul Kalam usually referred as A. P. J. Abdul Kalam was the 11th President of India for the term 2002 to 2007. Popularly known as the People's President he was the chief brain behind India's attainment of the nuclear status in the global arena and was known as the ‘Missile Man of India’ for his work on development of ballistic missiles and space rocket technology.

Last year it was noticed the presence of condolence messages about the demise of Dr A P J Abdul Kalam on banners held at tea shops and auto rickshaws. At first, it made me surprised and wonder why shop owners are displaying his picture and messages. In a country where hardly common men and women are aware about who the current President is, what is it that made these people showcase love and affection on his death? It was definitely not a political cause as Kalam was not a political leader. It was because this man touched every heart in a big and meaningful way. It was on his third visit to Rajiv Gandhi Indian Institute of Management (IIM) Shillong on July 27th, 2015 when the former President and world renowned scientist collapsed while giving lecture to the students.

An ineffaceable mark is created in the minds of millions of Indians by our “People’s President” the late Dr APJ Abdul Kalam. Very few eminent public figures that history has witnessed had created such a deep influence even after their demise.  This magical name sends an electrical signal to every soul in our country who wants to be truly successful. He always preferred to converse with people directly instead of using the web or the electronic media. He was very less aware of protocols and security measures. He loved spending quality time amongst students in various schools, colleges and universities to interact with them and to inspire them to be better individuals when they grow up.

There are numerous experiences of people who worked by the side of this man who has been deeply motivated by his honest care, affection and thoughtfulness. It was once, under a very tight project launch a scientist working under him requested an early leave as he was supposed to take his son to an exhibition. Engrossed in his work, it was three hours late when the scientist realised that he forgot keeping his parental duties. Going back home with a guilty heart he was amazed to know that his son was not at home. Instead he was at his exhibition. It was Dr Kalam, who on noticing that the scientist was not leaving his work, thought to keep his father’s promise to the child by taking him to the exhibition personally. It clearly shows how much he valued his men. Because it is men who makes or breaks an organisation.

Small instances like refusing to sit on a chair offered to him on a seminar at IIT Varanasi just because its size was bigger than the rest shows how much he believed in being equal. Personally sending a handwritten thank you card to a kid who sketched his portrait inspired by his book “Wings of Fire” shows how polite he was to respond and acknowledge every good and positive deed.

He was one of those respected souls in this country whose contribution to our society as a scientist, leader and President has been most prominent. Once his terms as a President were over, Kalam visited various reverend institutes and universities present in India as their visiting professor. He loved sharing knowledge and motivating people towards the big picture of life.

Early childhood and education - It was unknown to parents Jainulabdeen and Ashiamma that one day their son will become the first citizen of India. Dr A.P.J Kalam served the country as its 11th President since year 2002 till 2007.  The pure heart of the child got its nurture and care in the humble surroundings of the south Indian state of Tamil Nadu. Born in a poor family Kalam soon understood that he has to sponsor his own education by all means. From a very early age Kalam started earning his and his families living by distributing newspapers. However, money never lured him away from gaining knowledge. His ever growing thirst to gain knowledge compelled him to complete his studies successfully. In the Institute of Technology in Madras after studying aerospace engineering he graduated in the year 1960 after which he joined in the DRDO or the Aeronautical Development Establishment of the Defense Research and Development Organization as their scientist.

Career-  This multi dimensional persona was a well known scientist exhibiting enormous and endless for science and technological research and development. It was he who made our country nuclear in its truest sense. It was in the year 1974, under the supervision of Dr Kalam, India underwent its first nuclear test. Next came the Pokhran –II in the year 1988. It was through these nuclear tests Dr Kalam showed the world India’s position and power in nuclear technology.

Awards and achievements - His works awarded him three renowned awards from the Govt. of India namely- Padma Bhushan, Padma Vibhushan and the Bharat Ratna. In the year 1997, Kalam was also awarded with the Indira Gandhi Award for National Integration. He was awarded the Veer Savarkar Award in the year 1980 and the Ramanujan Award in the year 2000.From 40 universities all across the world, Kalam received honorary doctorates.

Works – He was the proud author of numerous inspirational books like “India 2010”, “Ignited Minds”, “Mission India”, “The Luminous Sparks”, “Wings of Fire” and “Inspiring Thoughts”.  

His life, work and beliefs are filled with examples and inspirations. He will continue to inspire us forever. And this is the real reason why people from all the sections of the society spontaneously shown love for this great human being on his sad demise at IIM Shillong on 27th July 2015.

Algebra Mathematics Explained with easy to understand 3D animations

Algebra (from Arabic "al-jabr" meaning "reunion of broken parts"^[1]) is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols;^[2] it is a unifying thread of almost all of mathematics.^[3] As such, it includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.

Elementary algebra differs from arithmetic in the use of abstractions, such as using letters to stand for numbers that are either unknown or allowed to take on many values.^[4] For example, in ${\displaystyle x+2=5}$ the letter ${\displaystyle x}$ is unknown, but the law of inverses can be used to discover its value: ${\displaystyle x=3}$. In E = mc², the letters ${\displaystyle E}$ and ${\displaystyle m}$ are variables, and the letter ${\displaystyle c}$ is a constant, the speed of light in a vacuum. Algebra gives methods for solving equations and expressing formulas that are much easier (for those who know how to use them) than the older method of writing everything out in words.

The word algebra is also used in certain specialized ways. A special kind of mathematical object in abstract algebra is called an "algebra", and the word is used, for example, in the phrases linear algebra and algebraic topology.

FLUIDS MECHANICS FULL LECTURES (PART 1 TO 11) CLASS 11 FLUID MECHANICS...

Fluid Mechanics

Fluid mechanics is a branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. Fluid mechanics has a wide range of applications, including mechanical engineering, civil engineering, chemical engineering, geophysics, astrophysics, and biology. 

Fluid mechanics can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint rather than from microscopic. 

Fluid mechanics, especially fluid dynamics, is an active field of research with many problems that are partly or wholly unsolved. Fluid mechanics can be mathematically complex, and can best be solved by numerical methods, typically using computers. A modern discipline, called computational fluid dynamics (CFD), is devoted to this approach to solving fluid mechanics problems. Particle image velocimetry, an experimental method for visualizing and analyzing fluid flow, also takes advantage of the highly visual nature of fluid flow.

NEET (UG) 2017 Paper Analysis

National Eligibility cum Entrance Test paper was held on 7^th May, 2017 across India on various centres. Unlike previous year, NEET 2017 was held in only one phase covering all the topics. Physics, chemistry, zoology and botany were the major sections of the paper, each carrying a total of 45 questions. Each question carried 4 marks, with a penalty of 1 mark for wrong answer. Overall, the paper was tougher as compared to the NEET 2016. In this article, we give the NEET 2017 paper analysis based on different topics & their difficulty levels.

 

NEET 2017 Paper Analysis

NEET 2017 is organized by the Central Board of Secondary Education every year of the help of applicant to secure admission for MBBS and BDS courses in the top medical institutions of India.

This offline mode (pen-and-paper based) examination was held on 7th May, 2017. With a total length of three hours, the paper started at 10:00 am and ended at 1:00 pm.

NEET 2017 was conducted in 10 different languages, compared to 8 last year. Students attempted the test in English, Hindi, Tamil, Telugu, Marathi, Bengali Assamese, Gujarati, Oriya and Kannada. The last 2 languages were added this year.

The exam contained a total of 180 questions for a total of 720 marks. Each question of test paper contains 4 marks. This would include 45 questions from Physics and Chemistry and 90 questions from Biology (ei., Botany + Zoology). Each question would be of an objective type with 4 choices.

 

Analysis by EQKota experts

Weightage

This year, both 11^th and 12^th standard syllabus contributed equally to the paper.

Chemistry section 21 questions from 11th standard and 24 questions from 12th standard. The paper had 14 questions from Physical Chemistry, 13 from Organic Chemistry, 13 from Inorganic Chemistry and 5 questions from General Chemistry.

Biology section was also balanced, with 44 and 46 questions from 11th and 12th standards respectively. The paper had 11 questions from Reproduction, 14 from Genetics and Evolution, 8 from Biology and Human Welfare, 4 from Biotechnology, 10 from Ecology, 10 from Diversity in Living Organisms, 7 from Structural Organization in Plants and Animals, 7 from Cell Structure and Function, 6 from Plant Physiology and 13 from Human Physiology.

BOTANY

ZOOLOGY

 

Difficulty

This year, the paper was moderate in both difficulty and length. Compared to last year’s paper though, this year was tougher on both points.

Physics is generally considered to be the toughest of the three subjects. This year’s paper was of moderate difficulty; with a lot of calculation-based questions. Compared to last year though, the paper was slightly tougher and lengthier.

Chemistry is generally of moderate difficulty and this year was similar to last year’s paper. Most questions were conceptual and application based. Students strong in both factors would not find it too lengthy either.

Biology is generally deemed to be moderately difficult and this year was no different. Compared to last year though, the paper was slightly tougher. Most question were conceptual, so those with strong concepts would find it solvable in time.

Opinions of NEET aspirants

This year saw the number rising to over 11 lakhs in comparatively last year’s 7 lakhs students who gave the exam at 104 cities across India. With over 50,000 medical seats in government and private institutions across India, the competition is a lot more intense in 2017.  However, the government has also estimated that 10,000 additional seats will be made available to the pool of candidates.

Reflecting upon this year’s paper, student opinions differed quite a bit. Here’s what some aspirants had to say about the overall difficulty.

1.     Anjali Sharma.: “Physics was lengthy and tougher. There were a few questions that needed a lot of working and calculations on. Chemistry was slightly little simple. The Biology segment was of medium difficulty, though I expected a tougher paper. It was definitely easier than last year’s paper of chemistry. Biology was approximately same. Physics was a lot lengthier than last year.”

2.     Rahul Jain.: “The paper’s difficulty was medium and not very lengthy but little confusions. Most questions were asked from the NCERT book. Biology was the easiest of the three segments. Chemistry was also rather easy. While Physics was the hardest of all subjects, most questions were solvable and calculative in the given time.”

On the whole, students seem to be rather satisfied with their performance and expectation of test paper. They now optimistically await the results that are scheduled to be declared on 8th June, 2017.
