About the Book

Nowadays, Information and Communication Technology (ICT) touches every aspect of our life. When we get up in the morning, we check our smartphones for any missed calls, SMS, and WhatsApp messages that include audio clips, video clips, and sometimes computer-generated cartoons and animations. Many of us read the latest news and email on our smartphones, tablets, or laptop computers that are connected by Wi-Fi to the Internet. Researchers search the World Wide Web for relevant research papers using a search engine, usually Google. To hear an old favourite song, we turn to YouTube. Books are bought by logging on to Flipkart or Amazon and placing orders. Air tickets are booked by logging on to an airline’s or travel agent’s websites. Train tickets are booked on the IRCTC site. Banking is done from home using Internet banking. When we want to go out and need a taxi, we use Ola or Uber App installed in our smartphones to find out in a map where taxis are, and the time it will take to get one. The taxi driver uses his phone to find our location (found by GPS) from the map on his smartphone screen. The fare is automatically deducted from our pre-paid accounts with Ola or Uber. Else, we may use a digital payment App such as Paytm or BHIM. If the Internet cannot be accessed for some reason, it is extremely inconvenient as a lot of our work gets delayed. Undoubtedly almost everyone has become dependent on ICT in their daily life. ICT has spawned many new industries that employ millions of people. All this has happened in a relatively short period of about seventy years.
In a short span of seventy years, Information and Communication Technology has changed the way we live. Often, we wonder how we lived without the Internet and smartphones!

PHI’s recently released book GROUNDBREAKING INVENTIONS IN INFORMATION AND COMMUNICATION TECHNOLOGY by Rajaraman is written in a simple style without too many jargon terms to allow anyone with a pre-university education to understand and appreciate how ICT has developed. 
  • What do we mean by a “Groundbreaking Invention”? Some of the meanings of the word “groundbreaking” taken from dictionaries are:
  • “innovative, pioneering” (Oxford Dictionary)
  • “A very new and big change from other things of its type” (Cambridge Dictionary)
  • “Introducing new ideas or methods” (Merriam-Webster Dictionary)
  • “Something innovative, pioneering or that has never been done before” (Your Dictionary)

Of these four meanings, the one given by the Merriam-Webster dictionary is closest to the criteria that are used to select the fifteen groundbreaking inventions presented in this book. What then are the criteria to classify an advancement in ICT as a groundbreaking invention? The following criteria are used:
  1. The idea should be novel.
  2. It should fulfil a need.
  3. It should improve our productivity.
  4. It should change the way in which computing is done, and computers are used.
  5. It should lead to innovations.
  6. The invention must have a long life and be continuously used and not be transient.
  7. It should create new industries that lead to further innovations and may, as a consequence, disrupt some old industries.
  8. It should transform the way we live and thereby result in societal changes.

Every groundbreaking invention does not need to satisfy all the above criteria. If it meets a majority of these, the author of this book has classified it as groundbreaking.

The book identifies and explains fifteen groundbreaking inventions in ICT from 1957 to-date. The first chapter explains what is meant by the term groundbreaking invention and the criteria that have used to identify groundbreaking inventions. The second, third, and fourth chapters describe the inventions, how they were invented and the biographies of prominent inventors. The biographies are given in Boxes. They may be skipped while reading about the inventions and read afterward to get an idea about the inventors and their careers. In the fourth chapter, concluding remarks are added that discuss whether there are some common features in the inventions and about the nature of the inventors and why they succeeded.

In this book, Dr. Rajaraman has described the following for each of these inventions: 
  • History of the invention 
  • A brief biography of persons who were associated with the invention
  • Why the author considers the invention as groundbreaking
The inventions are grouped as follows: 
  • Between 1957 and 1974 (the first four inventions)
  • Between 1975 and 1984 (the middle five inventions) 
  • Between 1985 and 2011 (the last six inventions)
Each group of inventions is described in a chapter. 
This book seeks to answer the following questions lucidly to a non-specialist general reader:
  • How did this revolution happen?
  • What groundbreaking inventions led to this revolution?
  • Why are they groundbreaking inventions?
  • Who were the innovators and inventors of these technologies?
  • What led them to these inventions?
Fifteen groundbreaking inventions: Fortran, Integrated Circuits, Relational Database Management Systems, Local Area Networks, Personal Computers, Public Key Encryption, Computer Graphics, Internet, GPS, World Wide Web, Search Engines, Digitisation and Compression of Multimedia, Mobile Computing, Cloud Computing, and Deep Learning (AI) are described cogently by Professor V. Rajaraman, a doyen of Computer Science education and research in India.

New eBook on Fluid Mechanics to Tackle the Subject in MATLAB Environment

Here we want to present our new release on Fluid Mechanics, devoted to problem-solving with the use of MATLAB, titled Fluid Mechanics: Problem Solving Using MATLAB (eBook ISBN: 9789389347630). 

The Scope of Fluid Mechanics

Fluid Mechanics is transformed from a fundamental subject to an application-oriented subject. It constitutes the foundation of what is now referred to as “Water Engineering,” entailing hydraulics, hydrology, groundwater engineering, environmental engineering, irrigation and drainage engineering, and hydropower engineering. It is, therefore, the first course at the undergraduate level in these branches of water engineering. Hence, there is a need to develop a book that focuses on problem-solving. Furthermore, these days there is umpteen computer software available which can be employed to solve a wide variety of problems, and such software is easily accessible to undergraduate students in most engineering departments. One of the most popular and versatile software is called MATLAB. Fortunately, many students in the beginning years of their engineering studies become well versed in the application and use of this software.

 Here is an overview of the topic this book is about.

Books on Fluid Mechanics

Over the years, numerous experts introduced more books on the theme. The majority of them are rather theoretical with numerical problems and derivations. However, due to the increase in computational facilities and the availability of MATLAB and equivalent facilitators, the subject is also transforming into a computational perspective.
Admirably Professors K. Srinivasa Raju and D. Nagesh Kumar, who are well established and recognized scholars in water engineering, recognized the need to bring fluid mechanics to the fingertips of undergraduate students and embarked on a journey to address this need. Both these professors are highly accomplished and have long years of experience in teaching fluid mechanics at the undergraduate level. 

Organization of Book

Fluid Mechanics: Problem Solving Using MATLAB is probably the first book that is exclusively devoted to problem-solving with the use of MATLAB. This book will be an excellent supplement to a regular fluid mechanics book used in teaching fluid mechanics at the undergraduate level. This book contains problems on virtually all topics that are covered in undergraduate fluid mechanics courses plus more. 

The subject matter of the book encompasses:

  • Sixteen chapters that are devoted to:
  • Fluid properties
  • Pressure measurement 
  • Hydrostatics 
  • Buoyancy
  • Hydro-kinematics
  • Bernoulli applications 
  • Momentum principle
  • Orifices and mouthpieces
  • Notches and weirs 
  • Flow-through pipes
  • Laminar flow
  • Turbulent flow
  • Boundary layer theory 
  • Drag and lift
  • Open channel flow
  • Dimensional analysis
  • 161 example problems supported by corresponding MATLAB codes compatible with the 2016a version (
  • Eight derivations 
  • 162 exercise problems 
  • Question Bank comprises 261 representative questions and 120 numerical problems
  • An appendix containing selected MATLAB commands
A most impressive feature is a live demonstration of representative codes (12 in mp4 format and 161 MATLAB codes) that are available in the Learning Centre Section at, for the benefit of readers so that they can understand the intricacies of coding. 

The book is easy to read and follow and will have a great deal of appeal to undergraduate students. It will be equally appealing to faculty members who are engaged in teaching fluid mechanics at the undergraduate level. It can support undergraduate students in fluid mechanics and can be referred to as a text/reference book. Solution Manual is available for instructors who adopt the book for classroom teaching.
The detailed information about the book is available at its webpage:
