Professor Hawking distributed numerous books handling the key inquiries concerning the universe and our reality. Stephen wrote and published numerous logical papers and address notes.

Hawking has explained the whole universe very briefly,

He explains a lot of things related to time, dimensions, secrets of the galaxies, etc.

He put forward his views about the universe and different theories given by the great scientist of the world from ancient to the present time.

He wrote and published so many books about the universe, in each book he explains neatly about the galaxy.

Here we are trying to put best 7 Top most books written by hawkings to explain about the universe, In his books, he proved that how genius that he was.

I simply loved the book.

The way Mr. Hawking explains the intricacies of the quantum level universe while taking a stab at the macro level relativity concepts is unique.

**1.The Theory Of Everything **

In this book, Hawking has explained the whole universe very briefly.

The book explains following things deeply

*ideas about the universe

*expanding universe

*black holes

*origin and fate of the universe

*the direction of time

* the theory of everything

the book explains everything from beginning to the end of the universe. it shows the interaction between science and natural powers. science lovers it will lead ur knowledge to a next level

A one more interesting book which explores cosmological concepts in a very simple manner.

## 2. Brief History Of Time

An Excellent book for everybody which was easily understood even not having much knowledge of physics also. It is a knowledgeable book which helps to understand the higher physics concepts which are pretty cool.

After reading this book you will try to find the reason for the existence of GOD.

By reading this book Now you will journey into Hawking's UNIVERSE. You will enter the region where you have never been before.

This book is excellent for a science lovers.

## 3.The Grand Design

In this book, Hawking reviews the basics of quantum mechanics, including the elementary particles (e.g., quarks, bosons, etc.) that have been discovered thus far. He also covers the basics of string theory.

In this book, the "The Game of Life" chapter, which is a very interesting simulation created a while back. The Game of Life demonstrates how narrow our science may be in trying to discover the fundamental laws of the universe.

In fact, it almost depressed me to think that we are so limited by our human perception in trying to discover these fundamental laws.

Some negatives about the book include that it took too long to really get into the interesting questions. The first third or half of the book is mainly a history of a science lesson.

Illustrated with rarely seen photographs, this witty and candid account introduces readers to the inquisitive, quipster of a schoolboy who was called ‘Einstein’ by his classmates;

The man who once placed a bet on the existence of a black hole; and the loving husband and father striving to gain a strong foothold in academia.

## 4. My Brief History

"My Brief History" is a Journey of Stephen Hawking ’s from his boyhood during post-war London to his years of international acclaim.Illustrated with rarely seen photographs, this witty and candid account introduces readers to the inquisitive, quipster of a schoolboy who was called ‘Einstein’ by his classmates;

## Gate 2019 all India exam preparation tips to Crack the exam

Now a days GATE is becoming more popular Because from the year 2012 onwards Most of the PSU’S recruiting people through GATE score and students showing interest on higher education like M.Tech/M.S are increasing every year in India. It is easy to crack GATE exam (I cracked GATE –EC 2012 and I was studied in NIT) if you follow these simple steps. I already posted the details about GATE in my previous posts you can check it to know more.

**Why GATE 2019 exam?**

Because GATE exam is important to do M.Tech/M.S in Top universities like IIT’S,NIT’S ….Not only that its very important to get jobs in PSU’S like NTPC,BHEL,BEL,HPCL….and also every year BARC is recruiting scientists through GATE score so many peoples have a question that how much score is needed to get all these things??? I will clear this doubt in my future posts,today my topic is how to prepare for GATE.

####
**Steps to Crack GATE easily:**

**1.**

**Syllabus:**Collect syllabus from GATE website or you can download from here.

**2.**

**Research on your knowledge:**Check the syllabus and know about yourself, i.e how much knowledge depth you have in those subjects because all these subjects you have already learnt in your graduation and make a list of subjects you are poor and on which subjects you are good.

**3.**Check In how many subjects you are poor and good from the list which you have prepared.If you are not clear with basic subjects, its better to join in any good coaching centers or learn subjects online from NPTEL ,MITOCW websites. Now a days some coaching centers offering online classes too so if you have interest you can check their websites for more information.

**4.**

**Previous papers & Making a short Notes:**If you have some knowledge in subjects and you want to learn more in depth you can also take classes online from NPTEL and MIT those offering these courses for free and also follow at least two standard text books for each subject. Before studying any subject once check previous GATE papers and note down the areas on which questions are asked. First choose the subject which you are poor, while studying or learning focus more on those areas in which they are asking questions and

**note down the important points in a separate notes it will useful to refer before the exam**.

**5.Practice makes Man perfect:**After studying one subject you need to practice previous questions of the respective subject from GATE and IES papers you can download these papers online or you buy it from market/online .

**Why IES papers**,sometimes in GATE exam they give direct one mark questions from these IES papers so you need to practice those papers also to differentiate your gate score from others.

**Practice more and more problems to crack gate easily.**

**6.**

**Have a faith in your self:**Without self motivation and self believe, no one in this world can achieve anything. Its tough to crack gate if you don’t have any plan or time table.Normally 3 to 4 months of serious study will be sufficient for the preparation so prepare your own time table now.

**7.Test series:**After completing your preparation take some online test series exams conducted by some institutes(like Gate Forum) that will helpful to know your preparation and also it gives confidence to the final GATE exam.
