How to prepare for GATE, PSU, IES?

How to prepare for PSU using my notes?

Please follow the step by step procedure given below for preparing PSU where only objective type
questions are asked.
General guidelines

I found that in all competitive examinations similar type of questions are asked. They are alike but not the same. The questions are not repeated but the theory (Funda) which needed to solve the question
remains same. So you don’t need to remember the questions and answers but you must remember the
funda behind it. Previously it was not like that. Because that time the
question paper was set by PSU people. Most of the questions were copied from the book of R.K. Jain. Now every PSU papers are set by Professors of IITs or renowned Institutes. Professors don’t copy questions but they check student’s fundamentals of the subject. So we must be prepared with fundamentals. That’s why funda is repeated.

You know that in the engineering books are not made for objective type questions. The theory involves
rigorous derivations, enormous calculations etc and our University examination is also conventional
type. We have to prepare for Objective Questions. For that first read the book carefully try to solve my
question set with your own and check with my explanations. Mark with a pencil in your books which
funda is needed to solve this problems.

For clearing doubts or any time
if you have any confusion Open a PDF file from the folder “Search for solving Question” and press key Shift+Ctrl+F then type any
keyword and search. Use down arrow key in the result.
Doing this 99% confusion will be clear. If confusion is not clear yet call me or mail me.

Top 10 Most Amazing Elements

It’s hard to think of elements being, of all things, ‘cool’, but the basic building blocks of every thing that has come into common use in the world is comprised of the elements. From the very air we breathe (oxygen, nitrogen, and other trace gases) to simple medications we take (comprised of many things including calcium, magnesium, copper, potassium), all are found, or in a few cases, created, here on Earth. Though many of the elements found in gaseous forms can be considered toxic, many in liquid and solid forms can be equally as deadly: argon, gallium, and chlorine to name just a few. There are many that stand out because of their use, visible state, or exceptionally short life spans. Here are but ten (and, of course, a cool bonus).

10. Mercury – Hg

Mercury also called quicksilver, is an element that has the symbol Hg (Greek: hydrargyrum, meaning watery or liquid silver) with an atomic number of 80. A heavy, silvery metal, mercury is one of the elements that are liquid at or near room temperature. Mercury is used in thermometers, barometers and other scientific apparatus, though many concerns about the element’s toxicity have led to said thermometers being largely phased out in favor of alcohol-filled or digital. It remains in use in scientific study and research applications, and in dentistry. Mercury is mostly obtained by reduction from cinnabar, a mineral. Mercury occurs in deposits throughout the world and it is harmless in an insoluble form, such as mercuric sulfide, but it is poisonous in soluble forms such as mercuric chloride or methylmercury. Watch the video clip above for great footage of mercury vapor.

9. Magnesium – Mg

Magnesium is the eighth most abundant element in the earth’s crust, though not found in nature in its
elemental form. It is a Group 2 element, called an alkaline earth metal. Magnesium tarnishes slightly in air, and finely divided magnesium readily ignites upon heating in air and burns with a dazzling white flame. Normally magnesium is coated with a layer of oxide that protects magnesium from air and water. Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain regular muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure, and is known to be involved in energy metabolism and the synthesis of protein.

8. Krypton – Kr

Krypton is present in the air at about 1 parts per million. The atmosphere of Mars contains a little (about 0.3 ppm) of krypton. It is characterized by its brilliant green and orange spectral lines. Under normal conditions krypton is colorless, odorless, fairly expensive gas. Solid krypton is a white crystalline substance with a face-centered cubic structure, which is common to all the “rare gases”. In 1960 an international agreement changed the definition of the meter in terms of wavelengths of light emitted by the krypton-86 isotope. This agreement replaced the much-older standard ‘meter’ located in Paris which was a metal bar made of a platinum alloy (the bar was originally estimated to be one ten millionth of a quadrant of the Earth’s polar circumference). Many window companies now use Krypton to fill sealed panes in order to reduce energy waste, and the gas can also be used to detect leaks in industrial sealed containers.

7. Curium – Cm

Named for famed physicist Marie Curie, curium is made by bombarding plutonium with helium ions. So radioactive it glows in the dark. Several kilograms of curium are produced each year. As curium is
only available in extremely limited quantities, it has few uses; however, it was used on a Mars mission as an alpha particle source for the Alpha Proton X- Ray Spectrometer. Curium is potential isotopes power source as it releases three watts of heat energy per gram gram. Most normal individuals will never normally encounter curium as it does not occur in nature and is only produced in limited quantities. Louis Werner and Isadore Perlman created a visible sample of curium-242 hydroxide at the University of California in 1947 by bombarding americium-241 with neutrons.

6. Strontium – Sr

Strontium is found chiefly as celestite and strontianite. The metal can be prepared by electrolysis of the fused chloride mixed with potassium chloride, or is made by reducing strontium oxide with aluminum in a vacuum at a temperature at which strontium dissolves off. Strontium is softer than calcium and decomposes in water more vigorously. It does not absorb nitrogen below 380oC. It should be kept under kerosene to prevent oxidation. Freshly cut strontium has a silvery appearance, but rapidly turns a yellowish color with the formation of the oxide. The finely divided metal ignites spontaneously in air. Volatile strontium salts impart a beautiful crimson color to flames, and these salts are used in pyrotechnics and in the production of flares. Natural strontium is a mixture of four stable isotopes. The primary use for strontium compounds is in glass for color television cathode ray tubes to prevent X-ray emission. If you want to see a future rocket scientist having a play with Strontium, here you go .

5. Lutetium – Lu

In 1907 Georges Urbain was credited with the discovery of the element and won the right to name them, although chemists later changed the spelling of lutecium to lutetium. Today, lutetium is primarily obtained through an ion exchange process from monazite sand ((Ce, La, Th, Nd, Y)PO4), a material rich in rare earth elements. Lutetium is one of the most difficult elements to prepare and has no large scale practical uses, although some of its radioactive isotopes can be used as a catalyst in
the cracking of petroleum products and a catalyst in some hydrogenation and polymerization processes. Lutetium-176 has been used to date the age of meteorites. Lutetium Aluminum Garnet has been proposed for use as a lens material in high refractive lithography.

4. Chlorine – Cl

We all know never to mix chlorine with ammonia, right? Well, besides that potentially devastating fact, chlorine is widely used in making many everyday products. It is used for producing safe drinkingwater the world over. Even the smallest water supplies are now usually chlorinated. It is also
extensively used in the production of paper products, dyes, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products. Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine. Organic chemistry demands much from chlorine, both as an oxidizing agent and in substitution, since it often brings many desired properties in an organic compound when substituted for hydrogen, as in one form of synthetic rubber.

3. Aluminum – Al

Remember the boom of aluminum siding back in the day? Well this stuff has thousand-and-one uses from soda cans to kitchen utensils, outside building decoration, and in thousands of industrial applications where a strong, light, easily constructed material is needed. Although it’s electrical conductivity is only about 60% that of copper, it is used in electrical transmission lines because of its lightweight. Pure aluminum is soft and lacks strength, but alloyed with small amounts of copper, magnesium, silicon, manganese or other elements impart a variety of useful properties. These alloys are of vital importance in the construction of modern aircraft and rockets. Aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. These coatings soon form a thin layer of the protective oxide and do not deteriorate as do silver coatings. They are used to coat telescope mirrors and to make decorative paper, packages, and toys.

2. Zirconium – Zr

It is used extensively by the chemical industry where corrosive agents are employed. Zirconium is used in vacuum tubes, as an alloying agent in steel, in surgical appliances, photoflash bulbs, explosive primers, rayon spinnerets, lamp filaments, etc. It is used in poison ivy lotions in the form of the carbonate as it combines with urushiol. With niobium, zirconium is super-conductive at low temperatures and is used to make super- conductive magnets, which offer hope of direct large-scale generation of electric power. Zirconium oxide (zircon) has a high index of refraction and is used as a gem material. The impure oxide, zirconia, is used for laboratory crucibles that can withstand heat shock, for linings of metallurgical furnaces, and by the glass and ceramic industries as a refractory material. Its use as a refractory material accounts for a large share of all zirconium consumed.

1. Elements 112-118 Ununbium, Ununtrium, Ununquadium, Ununpentium, Ununhexium, Ununseptium, Ununoxium

Relatively new to the Periodic Table (they weren’t even heard of when I was in High School), elements 112-118. They are completely man made by bombarding specific atoms of one element with
specific atoms of another thereby separating each into an entirely new element only stable (though not necessarily visible) for a fraction of a fraction of a second. Ununbium was first created on Feb. 9th, 1996 in a lab in Germany. This element was created by fusing a zinc -70 nucleus with a lead-208 nucleus by accelerating zinc nuclei into a lead target in a heavy ion accelerator. The two ununbium nuclei so produced had a mass number of 27. On Feb. 1, 2004 the discovery of ununtrium and ununpentium were reported by a team composed of Russian scientists and an American scientist at the Lawrence Livermore National Academy. Most of the others were created or discovered much in the same fashion in different parts of the world since then. As of yet, since none of these have been witnessed for more than a second, their inclusion remains suspect and under investigation.

How should GATE be cracked within 3 months ?

The answer for that question solely depends on You.

Here are some points that would help you :

1. Analyze Yourself

I am just a random guy on the internet,you can't. solely depend on my answer. First try to analyze yourself. Go through the syllabus and make a note that how much good you're with your syllabus. You can find the amount of syllabus you've covered by this prepmeter.
Analyze your preparation level

2. How Good are you?

Now you have gone through your syllabus and can know your weak topics.Try to focus more on them.Try to allocate as much as time as possible for those topics.And be intelligent enough to leave the topics that aren't necessary.

3.Follow Standard Textbooks

I can't stress that enough.Majority of my friends who are preparing for GATE exams bought some Mock test papers and were trying to solve them.They are more interested in knowing the technique than learning the topic.They all stuck with all the topics and were solely relying on the
"key".Don't be such kind of a person.Learn from standard textbooks they help you in clearing your basics.

Education is like a house,the basement has to be strong for the house to cherish.

4.Connect Everything

I once read a quote,it says like

" Education is learning random things.Knowledge is about
connecting all those things".

All your subjects are related to one another. So if you read a subject well then it will help you in understanding the other subject. Study SOM before MD. (Sorry! I'm a ME guy).

5.Practice.

Practice and Practice even more Lock up yourself in a room.Study a subject and solve all the questions regarding that subject in previous papers.There will be some topics in which the IIT's concentrate more.Find them and practice them even harder.If you're in college,Read the topics at home and go sit in the last bench of your class and try solving those questions. Never stop practicing.

6.Success comes at a pay

As the GATE exam is about to approach just try to give more time for your preparation.There will be lot
of time you would have been wasting in your day. Just try to minimize that.
DON'T USE INTERNET UNLESS IT IS ACADEMIC ORIENTED.(You can have
a little relaxing time on it but make sure it doesn't count as a distraction).

Give all of your effort.

What is wrong with the Indian education system in terms of growth?

Read all the answers before agreeing to the following consolidation.

The main types of answers appear to be:

1) Half the country does not even have access to proper education, and only a small fraction can go to university.

- Lack of quality primary education for the poor

- Limited seats in Universities

2) Everything is about rote memorization, leading to behaviour which encourages cramming and
forgetting rather than life long learning.

3) Standardized testing determines everything, and aptitude of students is not recognized outside this format

4) Lack of diversity in the subjects you can take in college (e.g. can't double major in Math and German. like you can in the USA)

5) Extreme pressure from parents / society to use education for financial security = CSE degrees for programming jobs or medicine. Societal pressure to get into the "right schools", not only for the
education aspect but to ensure good job/ marriage prospects, in general success in life. Little incentive to take risks and follow own interests or encourage creativity. Generally conformist culture, which makes educational achievement the only thing that matters to social standing.

6) Additional extreme pressure due to limited seats resulting in very intense competition between students.

7) Reservation system

8) Management quota system What is management quota?

9) Government control of education/ Government Monopoly in education.

10) Right to Education Act.

11) Education sector is closed to for-profit organizations.

12) Few opportunities and flexibility to cross over into different streams of education.

What is wrong with Indian Education?

So..what is the definition of wrong when it comes to education ?

Lack of well rounded education . Nerds are restricted to books while jocks are restricted to practice nets. Unfortunately, nerds can benefit a lot from sports and learn team dynamics and how to work along with other people. Jocks on the other hand can learn a few things like critical thinking and logical reasoning.

Absence of disruptive innovators and rebels in our society . Like the commonly quoted Steve Jobs, we do have a lack of innovators (small when compared to our huge population) in our country.

What we instead have in our country is nation of sloggers who are restricted by our underdeveloped society's definition of success and cramming in spite of unhappiness to get into an engineering college and later to get the next promotion. This is completely done irrespective of if they actually care about the subject and work but rather by social conditioning which deludes them into thinking this how they can attain salvation.

Is it unfair to compare India with say...United States ?

Well take a completely unrelated metric ..life expectancy and compare the US, India and Singapore. Singapore was chosen by me because in the lifetime of our previous generation it managed to go from an under developed third world to a first world country. Now if you look at something as basic as life expectancy, India completely lacks behind US and Singapore with a life expectancy of something around 65. That would literally mean, if you are in your 30s, more than half of your life
is gone (yes you can argue it is for the entire nation and not specifically the urban population.) Anyway coming back to life expectancy, India is where Singapore was in the 1960s.

Now what does that say to us ?

India is still in the "survival mode" . Since its creation in 1947, we have been and still are in the "survival mode". What happens in the survival mode is that we do cost-benefit analysis of every decision in our lives and unfortunately in education, career as well as marriage. This explains why engineering is the overwhelming choice of the majority of the people in this country and in similar countries like China (who smartly have also recognized the potential of studying finance.) After we leave the "survival mode" as a nation, then only we will reach the developed stage like US and Canada where a significant fraction will choose subjects which they actually like and rather not forced by society to choose. After that when we reach the "Uber-Developed" status like Scandinavian countries, then the majority of our country, free of financial constraints will pursue their dreams.

Inspite of all this if we look at the enrollment in tertiary education in both US and India (assuming the correctness of the data, they are amazingly similar with approximately 20% enrollment with India doing better). As per the Annual Status of Education Report (ASER) 2012, 96.5% of all rural children between the ages of 6-14 were enrolled in school. This is the fourth annual survey to report enrollment above 96%. 83% of all rural 15-16 year olds were enrolled in school. However, going forward, India will need to focus more on quality.Gross enrollment at the tertiary level has crossed 20% (as per an Ernst & Young Report cited in Jan 2013 in Education News/ minglebox.com "In 2006, 19.5 percent of the adult population had attended college but had no degree, 7.4 percent held an associate's degree , 17.1 percent held a bachelor's degree , and 9.9 percent held a graduate or professional degree . The historic gender gap had practically vanished. New England had the highest proportion of college graduates, and the South Central states the lowest. "

So what is wrong with our curriculum ?

Actually nothing. Our curriculum is perfect and better than most countries. We are taught a vast majority of subjects (we will get to teaching methods later) which will allow us to recognize where our interest lies later in life. Hardly do you get Shakespeare and C++ being taught at high school level in developing country. Even in a developed country like Singapore, the syllabus is not so vast and people who might take History will not end up taking Geography. Unfortunately, our co-curricular activities lack behind a lot which would actually produce a well rounded individual. We end up being egoistical, individualistic narrow minded individual. However, till this crazy competition goes away, I doubt if any importance will be paid to co- curricular activities.

So who are we to blame ?

Parents, Teachers and Society "Cost Benefit Analysis of every Career Decision" When was the last time anyone studied engineering especially ECE because they liked it? They had been tinkering with circuits since young, taking apart radios and other stuff. When was the last time we studied anything because we liked doing it not because we can quote a huge starting annual salary?

Another consequence of the country being in the "survival mode", is that the insecurities of the parents are passed to the children over time and the ultimate objective is to achieve financial stability in whichever way possible.

"Myopic Definition of Success"

Standard definition of success common in our society is getting into a top engineering college followed by working in an unrelated field which would pay the most followed by getting into a B School to work in a field which you did not know even existed when you were in high school. Although I congratulate the successful ones from the top schools, what concerns me is that the definition of success is extremely myopic. Life is a long, long journey and although this might give you a good start, it will never determine where you end up.

In this way I will argue that we should stop blaming reservation as a curse of our society. Reservations can only stop you to a certain point and blaming them for "ruining your whole life" is extremely short sighted.

"Nation of Conformists"

We although will hate to admit, are a nation of conformists. Adventure and risk taking as a whole is just lacking in our DNA. We never explored China during ancient times (Marco Polo came from Italy), we never bothered to go to Africa till there were jobs for us. We are shit scared to be different. Every career decision is approved by our parents and society. We are just afraid of making a mistake and being pointed at. This comes from the very fact that since childhood, our teachers will label anyone different to be a "problem child" who needs psychiatric help, thanks to their limitations as incomplete human beings. We are so scared that we even make our parents choose our life partners.

Sometimes this delusion and comfort in success are gone by our early 30s and for the first time we want to live for ourselves. Unfortunately thanks to our small life expectancy and probably a family and child to support, this becomes a dream which we can never fulfill. Have you noticed why your father is grumpy all the time...this might be the very reason..!!

So is there any hope left ?

Yes! there is. This new generation is slowly breaking conventions and we are seeing more artists, more designers, more scientists.
Things will be much better by the next generation when people will choose careers out of their own free will.
