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.

## 5. The Universe in a Nutshell

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.

p-brane theories, string theories. Given that the book is not for people not involved with Physics, but for those who are,

## 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.

**1. Digital and Analog VLSI Design :**

In present technology revolution, in every electronic products like mobiles,computers,tablets, so on.. contains a chip which are based on VLSI technology. Let us take a big company INTEL which mainly focus on designing microprocessor chips which is used in computers with different clock speeds. To design those type of chips for consumer electronics, medical electronics, communication, aero-space, computers etc. they required highly skilled individuals is needed to meet this demand. So, this is the one of the highly demanded course which will useful to get in to the VLSI/ASIC design companies.

**Different Career or Job options after B.E B.Tech ECE****2. Embedded Systems :**

In our daily life, we use so many mechanical and electronic devices to make our work faster and easier like washing machine, lifts, escalator, pagers, micro ovens,etc.. so to do those works we need some processors which works for only a particular applications i.e like washing machine which only used to wash the clothes.To develop those type of applications we need to embedded some logical programs in processors which is written in the basic embedded program which is similar to C language. so to develop those type of applications most of the IT companies need engineers who have sound knowledge in hardware and software design.

Now a days the companies are more concentrate on the Internet of Things(IOT), It is one of the best course to get into a core companies, for this you have to learn Aurdino.

Now a days the companies are more concentrate on the Internet of Things(IOT), It is one of the best course to get into a core companies, for this you have to learn Aurdino.

**3. Computer Networking and System Security**

We all know how the internet is useful for us to know the information from all around the world. let us take “Facebook” a social networking sites which we are using daily and spending lot of time to connect with the other peoples but, have you ever think what happened when you open any website URL like www.facebook.com in your chrome or Mozilla Firefox or internet explorer(IE) browsers, as we are an engineers we have to think creatively “I believe engineers are only the creator in every industry”.Did you think what happened on backside of browser?Think!!. Back end there is a lot of protocols will run till the page opens completely , read any computer network book to know what is happening in internet world.

I am giving a small example component which is useful in networking i.e router which is used to route the packets from source node to destination node,here I am not going deep discussion about router if you want to know more about it learn from Google or any text book. Router is a physical device which consists of processor which was designed by VLSI peoples but they just design according to our requirements and networking engineers only know how to route packets efficiently in to the network for that they implements some routing algorithms and they designs the network based on requirements not only for that purpose they are used to secure the information in the network.

Cisco is one of the leading producer of routers, and so many companies need network engineers to design the network and to secure the information from threats. Networking & System Security is to address the industry needs of security aware network and system administrators.

**4. Wireless networks/Telecom:**

As we know how the telecom or wireless industries are growing fast as the usability of the wireless equipment by the user is growing.so,to meet the user standards these companies required talented peoples in these domain.

**5. Digital signal processing applications:**

**It has also an equal importance in the industry to embedded systems.Here this course used to develop some signal processing applications.**

**6. PLC/SCADA/DCS :**

I don’t have much knowledge on this course, but now a days its also becoming popular read more about this in the Hindu article

Nowadays most of the competitive exams are conducting written exam online, so practice and prepare your self through our new website: www.eqans.com

## Important Topics in Aptitude and reasoning for placements and competitive exams

**Quantitative Aptitude**is very important subject to test your problem solving skills. so, in every competitive written exam they asked questions from this subject, not only in written they may asked some brain storming puzzles in interview also. It is the one of the key concept to qualify written exam almost every students who know basic mathematics can solve most of the questions in the exam but the main problem is that the time management,the recruiters does not give enough time to solve the problems so one who has more practice the model questions before exam can easily solve in the exams.

I already discussed some good books for practicing aptitude,Reasoning and puzzles before,in that

**R.S.Agarwal**quantitative aptitude book is sufficient for most of the exam in both government and private sectors and also it useful for campus placement preparation.Here I want to tell some of the main important topics you must practice more for placements and any competitive exams.
Almost every topic is important,in exams they have a rights to ask any thing from any topic to filter the candidates. we must practice all topics,but we must concentrate more depth in some topics what I am discussing here because those topics are some what confusing and time taking so,to solve those problems in exams quickly we need more practice and mostly 70% of the questions will asked from these areas only.

The topics we must concentrate more are

**Chain rule,****Profit and losses,****Time and work,****ages based problems,****Pipes and cistern,****Time and distances,****Train problems,****Boats problems,****Simple interest****Compound interest,****clocks,****mixture problems,****probability.**

**Reasoning:**

**Coding and Decoding,****Blood Relations,****Series Completion,****Cubes and Dice,****Analogy,****Ranking,****Arithmetical reasoning,****Logics**.

For placement or private company exam preparation we need to practice more questions because they will ask some question as the level of CAT exam.
