  • Groundbreaking ICT Inventions: A Book Review by Pallavi Ghosh

    Our latest publication, “Groundbreaking Inventions in Information and Communication Technology” by V. Rajaraman is an informative and enjoyable read. The book is targeted towards those with a pre-university education and does not require readers to have any prior knowledge on the subject. It aims to provide an overview and historical background of various technological inventions in ICT (Information and Communication Technology) from 1957 to-date.

    Rajaraman explains 15 Groundbreaking Inventions in our history, using a uniform and consistent format, divided into 3 categories in accordance with the timeline within which they were created– ‘Between 1957 and 1974’, ‘Between 1975 and 1984’, and ‘Between 1985 and 2011’. Further, each groundbreaking invention is delineated through 2 subheadings: 1) What is the invention? ; 2) Why is it a groundbreaking invention? Alongside this, there are loads of interesting fact boxes and relevant information about the invention, organised in separate sections to educate the

    The relevance of the inventions is illustrated as we move through them serially,  in the order in   which they were invented, from  FORTRAN, Integrated Circuits, Relational Database Management Systems (RDBMS), Local Area Network (LAN), Personal Computers, Public Key Cryptography, Computer Graphics, The Internet, Global Positioning System (GPS), World Wide Web, Search Engines, Digitisation and compression of multimedia, Mobile Computers, and Cloud Computing to Deep Learning. Each of these technical terms are broken down and simplified for the benefit of the non-expert enthusiast. Moreover, the technical concepts related to these inventions are explained in a very simple and expressive language so that they are uncomplicated and fun to read.

    In the first introductory chapter, Rajaraman explains his reasons for creating this collection of 15 groundbreaking inventions. The author explains, “ICT has spawned a number of new industries that employ millions of people.” He elaborates upon the relevance of ICT and elucidates why it is important for all to have knowledge on the subject. Further, the author provides interesting facts about the history of ICT and introduced readers with ENIAC (Electronic Numerical Integrator and Computer), the first programmable general-purpose electronic digital computer, built in 1946 and UNIVAC (UNIVersal Automatic Computer), the first commercial computer made available in 1951. The author contends that the first groundbreaking invention in ICT was FORTRAN, a high-level programming language, created in 1957, which enabled scientists and engineers to use computers to solve complex problems easily.  The chapter contains countless fascinating fun facts.

    The subsection “What is a Groundbreaking Invention?” is particularly riveting since it clarifies the concept of a Groundbreaking Invention and defines the term citing authentic sources.

    Further, the author lists 8 criteria to classify advancement in ICT as a “Groundbreaking Invention”. These are:

    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.”

    Throughout the book these 8 criteria are used to explain why each of the 15 chosen innovations can be considered groundbreaking. This introduction also features a chronological list of the 15 groundbreaking inventions in ICT from 1957 – 2011.

    In the second chapter, “The First Four Inventions”, the author explains FORTRAN, Integrated Circuits, RDBMS, and LAN. The author provides background information about each invention, choosing to tell stories which are interesting and memorable. A fun fact included in this chapter is: John Backus, the inventor of FORTRAN, formed a group of diverse professionals (engineers, scientists, and programmers) to help write the program. For FORTRAN, out of the 8 aforementioned criteria, I found the final criteria, “Societal Impact” to be an excellent measure of its status as a Groundbreaking Invention. The author argues that the code has deeply affected the society we live in.

    On Integrated Circuits, the author notes that although the advent of transistors revolutionised electronics, it was soon to be found that building complex circuits with them was not as easy as it seemed. He then provides a detailed explanation of the ideas and experiments which led to the creation of the first integrated circuit. The technical concepts to be used alongside complex terms are written in a simple language and seem to flow into the reader’s mind. The author makes the readers feel as if they are reading a simple story rather than a book full of complex terms. The ‘fact boxes’, included in relevant topics, present thought-provoking information. For example, the section features box items like “How Does a Transistor Function as a Switch” and “How are Integrated Circuits Fabricated?” in a simple and easily understandable explanation blended with excellent diagrams. Next, the author gives reasons for why Integrated Circuits are a groundbreaking invention as per his aforementioned 8 criteria. A noteworthy point amongst these eight is that the invention “Leads to the start of a new industry” — paving the way for the industry of silicon devices and circuits, employing half a billion people worldwide. Later, in a similar format and under the same section headings the author explains RDBMS and LAN, illustrating why these inventions are, in fact, “groundbreaking”.

    In the third chapter, the author describes “The Next Five Inventions.” These are: Personal Computer (PC), Public Key Encryption, Computer Graphics, Internet, and GPS. Included in this chapter is a noteworthy box – a biography of Gary Kildall who is best known as the designer of the first operating system for Personal Computers. The book is peppered with such fact boxes which makes the experience of reading about the various technical concepts more interesting. Chapter 3 also contains some compelling and inspiring biographies, such as the biographies of computer wizards Steve Jobs and Bill Gates are written concisely and eloquently, making them more enjoyable to read than the information available online. Another noteworthy section in this chapter is the one on the Apple I, Apple II, and its subsequent models. These were the first computers to feature a keyboard, power supply, and display in their design. These computers also have a memorable name, Steve Jobs, attached to them.

    As the author explains why the relevance and historical background of the Internet makes it a Groundbreaking Invention, a very riveting detail in the history of the Internet is mentioned. The author explains the historical relevance of the internet by divulging that the internet was originally created as a defence weapon for the US Department of Defence (DoD). The author states, “J.C.R Licklider was convinced that a country-wide communications network to connect computers would be essential for the defence of the USA.”

    Amongst the reasons for why the internet is a groundbreaking invention, the most noteworthy are: 1) It leads to innovations: the internet has provided the format using which further inventions such as Search Engines, the World Wide Web, Video on Demand, Internet Radio, and Cloud Computing have emerged ; 2) Leads to the start of new industries: for example, e-commerce firms such as Flipkart, Search engine companies such as Google, and social networking companies such as Facebook ; 3) Societal Changes: the ability to instantly network with a large number of people online to communicate, consume information, buy, and sell has changed the way our society functions.

    Another notable section in this chapter is the one on GPS where the author provides the readers with some interesting facts. For example, the author states “Originally, GPS was intended only for the use of the defence forces of the USA.’ He informs us that GPS is still controlled by the US Department of Defence. He goes on to explain the political effects of this circumstance. This section on the geopolitical effects of the USA’s control on GPS is truly very compelling.

    In the final chapter, the author discusses the last six inventions: World Wide Web, Search Engine, Digitization and Compression, Mobile Computing, Cloud Computing, and Deep Learning. He uses the same organised format and easy to read language in this final chapter for clear understanding.

    Overall, what I found to be the best feature of this book is the format using which it is organised. The author presents his explanations of and relevant information on 15 groundbreaking inventions in a uniform format which consists of congruously repeating sections with consistent headings for each invention. Personally, the section I found most enjoyable in each chapter was the part where the author explains ‘Why’ – “Why is this invention a groundbreaking invention in ICT?”. This is since it is quite compelling to learn about why the author chose to write about these inventions in the first place. It is eye-opening to know that certain advancements in ICT can be set apart from others and called a “groundbreaking invention”.

    Arguably, the author does a commendable job at achieving what he set out to do. He explains the groundbreaking inventions in a simple style to allow anyone with a pre-university education to understand and appreciate how ICT has been developed.

    Readers will gain a deep understanding of 15 groundbreaking inventions in ICT from 1957 to-date and will find that this book is not only informative but also an enjoyable read.

    I highly recommend this book! Log on to https://www.phindia.com/Books/BookDetail/9789389347524/groundbreaking-inventions-in-information-and-communication

  • The “Other” In The Tempest: Chapter Review by Pallavi Ghosh

    The Tempest from our Shakespeare plays series features the original text of the play along with
    simple yet explanatory notes in the footnotes of the text. Alongside this, the textbook features a
    comprehensive introduction to the entire play, illustrative summaries of each act, and two critical
    essays giving a postmodern outlook to the play.

    This blog post will provide a detailed explanation of what’s in the book and help the reader
    understand what’s in store from them through a chapter review. Read on to find out more about
    this supplementary text and what it has to offer!

    The Tempest is a play about Prospero, the true Duke of Milan. Exiled by his brother Antonio
    who has usurped his place, Prospero plots to retake what is rightfully his. With the help of a
    spirit, Ariel, Prospero orchestrates a storm, ‘The Tempest’. The storm entraps the ship of his
    brother. Antonio and his crew are shipwrecked and make their way to Prospero’s isle. Prospero
    sets in motion a meticulous plot which results in the restoration of his Dukedom.

    The play poses several questions about territorial authority and claim. For example, the
    territorial limits of Prospero are questionable since he conquers an island which was already
    inhabited. Similarly, the crew of Antonio’s ship become Prospero’s subjects and must
    understand his rules of governance. These are unlike their understanding of the system of
    governance in Naples and Milan. Their presence on Prospero’s isle, therefore, is a point of
    discussion with great potential.

    Trapped on the island, Miranda experiences the world through the isolated isle. This natural
    world is very different from the kind of society Miranda would have otherwise had in Milan. This
    influences her perception of the world. On the isolation and consequent individualization of this
    character, Choudhary comments: “What Prospero banks upon is her ability to submit to his
    scheme, and part of it involves imbuing her with a form of knowledge that would equip her as an
    individual. The individualization of Miranda is an orchestration envisaged to address and
    engage with the world in more ways than one.”

    In the book’s introduction Choudhary grapples with such concepts to help students understand
    the dynamics between the tempest characters which Shakespeare attempts to create. The
    critical essays are selected to help contextualize the storyline as it unfolds.
    The first of the two critical essays the book features is “The Other in the Tempest: The Case of
    Caliban” by Margaret L. Pachuau.

    The essay grapples with representations of the “other” within the context of colonization. The
    relationship between Caliban and Prospero can be analogously seen as that between a
    colonizer and the colonized.

    The essay discusses how representations of Caliban as an enslaved “savage” being rather than
    the isle’s original inhabitant can aid the arguments of postcolonial theorists. The author
    describes various instances in which Propsero and Miranda, Caliban’s colonizers, otherize, entrap, mistreat, label as “savage”, and attempt to colonize Caliban. These instances can be
    seen as symbolic of the treatment meted out to colonized communities. The essay discusses
    and brings together the perspectives of various theorists on the colonized status of Caliban. The
    critical essay argues that the devaluation of the “other” within the play is similar to the
    otherization of the colonized in European colonies.

    Pachuau begins by analyzing the character Caliban who, by her interpretation, can be seen as
    the “other” within the play. He is often represented as a subhuman species, with his body being
    described as monstrous as compared to the human colonizer who has enslaved him. She
    argues that Caliban, being the original inhabitant of the island, has a greater claim to ownership
    over the isle than Prospero. She presents Caliban as a wronged, mistreated character who has
    been devalued and given the title of a “savage” by his colonizers, Prospero and Miranda. She
    explains that Prospero’s attempts to humanize Caliban and teach him his language is akin to
    the colonizing efforts made in the past.

    The author comments on Caliban’s ability to speak, noting that Miranda and Prospero believe
    that teaching Caliban to speak was a “gift”. Referring to ‘Can the subaltern speak?’ (Spivak
    1985), Pachuau notes that the so-called “Demi-devil” delivers the most elaborate and
    memorable speeches in the play. Although he has learned the language of his colonizer, he
    seems to be empowered by it. Her analysis of this character completely changes how the
    reader views Caliban. Refuting his image as the enslaved, sub-human entity within the play,
    Pachuau places Caliban in the centrestage, arguing that he is the rightful owner of the isle.
    Quoting Foucault, she asserts that power cannot be one-sided (from the ruler to his subjects)
    but comes from within. Therefore, a ruler’s subjects are powerful since power comes from within
    a group. She argues that due to this “web-like inclusiveness” of power, there is a sense of
    power in Caliban’s character, the enslaved subject of Prospero. She notes that ‘Caliban
    challenges Prospero’s authority when he points out that Prospero’s language gave him the
    ability to “curse” his tormentor.’ After providing this unique perspective on Caliban’s character,
    Pachuau notes that Caliban’s name is a play on the word cannibal – a term which is associated
    with “savageness” by European norms. It may also be a play on the word “Cauliban” which
    means “black”.

    Other critical points of discussion in Pachuau’s analytical essay which are likely to be extremely
    helpful to students working with this play include interpretations of Caliban as a slave, colonized
    person, and victim which align with discussions in various postcolonial texts. Further, Pachuau
    makes a brief reference to the book Black Skin and White Masks by Fanon which analyzes the
    relationship between the lord and bondsman, drawing from Hegel’s propositions on self-
    consciousness. The book states that ‘The element of recognition is lacking in the relationship
    between the white master and black bondsman.’ Pachuau compares this assertion to the
    dynamics between master and slave within the book, presenting a detailed discussion. Further,
    the author asserts ‘learning the language of the colonizer is a prerequisite for any social
    advancement (as per a colonial mindset)’. This is since the colonized is always veiwed as
    inherently ‘savage’, ‘lazy’, ‘stupid’, and ‘other’ –  a’vile race’, as is the representation of Caliban
    within the play.

    Further, the essay compares portrayals of ‘the other’ in The Tempest to the ‘othering’ treatment
    meted out to the colonized in the history of colonizing efforts. She writes, ‘Prospero’s art
    represented the world of civility and learning in contrast to the ‘natural’ black magic of Caliban’s
    mother Sycorax’. Such a representation of the colonizer’s benevolent art as a contrast to the ‘uncivilized’ culture of the colonized is a common theme in history. She frames such a
    representation of the enslaved Caliban within the context of the decolonization movements of
    the 1960s and 1970s in Africa, the Caribbean, and Latin America. With Prospero’s culture being
    treated as the norm, Prospero derides Caliban even as he claims he has treated him with
    kindness in his attempts to humanize him.

    By raising such points, the essay does a commendable job at finding links between postcolonial
    theorists’ works and the portrayals of the “other” in the play. It analyses Miranda and Prospero’s
    justifications of their enslavement of Caliban and places these under question. It raises the point
    that the island rightfully belongs to Caliban – the original inhabitant.

    Whilst discussing criticism of European paternal rule, the author refers to Aime Cesaire who
    discusses the relevance of language in colonial imagery, continuing the discussion on
    Prospero’s gift of language to Caliban. The author writes, ‘Set in a colony – a  prototype of a
    Caribbean or African setting – in the throes of resistance and unrest, Cesaire.

    Pachuau continues on with the discussion on language by observing instances where language
    is used to portray the colonized as “other”. She gives the example of the dualisms of dark and
    light which Shakespeare portrays in his imagery to contrast the colonizers and colonized. She
    observes ‘The colonizer used words like light, knowledge and wisdom to refer to himself while
    he used terms like darkness, ignorance and elemental to describe the colonized’. She argues
    that language is used to devalue the colonized.

    The author concludes this highly informative essay by acknowledging that there can be
    counterarguments to her stance. She says that some critics have argued that Prospero is not a
    colonizer but simply one who was exiled and stranded on the isle he has taken over. He is, in
    this way, not unlike Caliban who is also stranded.

    She informs us that Prospero isn’t the only main character in the play and that Caliban’s
    character holds an important position within the dynamics between the characters. For example,
    she argues that Caliban is an important character since he holds aesthetic significance. She
    quotes Harold Bloom who says “Caliban has aesthetic dignity, and that the play is not wholly
    Prospero’s only because of him.” Pachuau concludes her essay by observing Caliban’s unique,
    inimitable character which contrasts our own self-concern as human subjects.

    Overall, the chapter accomplishes what this book from our Shakespeare series promises to do.
    It helps readers gain a deeper understanding of the play and view the characters through a new
    perspective – through the lens of postcolonial theory. As mentioned in the introduction, the essay
    demonstrates how The Tempest raises questions about Politics and Governance through its
    storyline and portrayals. The essay backs up its arguments with evidence from various
    reputable critics who have also written on the postcolonial questions raised within the play.
    This book is an excellent read for students and teachers who are working with Shakespeare
    plays. Making persuasive, clearly written, and well-evidenced arguments, this book’s strength
    lies in providing strong critical reasoning and analyses of the play.
