What is Computer Science, How Did It Start, and Why Do You Need It?

Hey everyone! Before moving on to other seriously mind-boggling concepts we thought to give you a little introduction to computer science itself. We all have some idea of what computer science is and why it matters, but let’s dig deeper. If you read the previous blog, you might recall the quote, “The best way to predict the future is to invent it,” and that same mindset applies to the origins of computer science. At its core, computer science is an abstract blend of mathematics, physics, and statistics—an evolving discipline that has shaped the world as we know it.

Many of us have always treated computer science as a solitary discipline, but in reality, it’s a clever combination of mathematics and science. The journey toward computer science is ancient, dating back to the invention of numbers, the discovery of gravity, and other foundational scientific milestones. But the very first foundations of computer science as we know it began when early mathematicians and scientists started developing the concept of algorithms, logic, and mechanical computation. Key figures like Charles Babbage, who designed the first mechanical computer, and Alan Turing, who laid the groundwork for modern computing with his concept of the "universal machine," which set the stage for the evolution of computer science into the transformative field it is today.



Computer science is based on the fundamentals of language, at its core, computers communicate through binary - a fundamental language of 0s and 1s that functions like a series of true/false questions. For instance, asking "Was Julius Caesar a Roman dictator?" gets stored as 1 (true) in the database. These binary digits operate through transistors, where 0 represents a lower energy state and 1 represents a higher state. While a single bit (1 or 0) might seem insignificant, eight bits combine to form one byte - the basic unit of digital information. These bytes, through various combinations, create all computer data we use and can be converted into different formats like decimal, octal, hexadecimal, and ASCII, forming the foundation of our entire digital world.

Computer science isn't just about coding - it's woven into every aspect of modern life, starting before birth with ultrasound imaging and fetal monitoring. From the smart toys that entertain children to the robots cleaning our homes, from TV remotes to smartphones, technology powered by computer science shapes our daily experiences. In healthcare, it enables everything from medical diagnostics to patient records. In transportation, it powers navigation systems and vehicle controls. The business world has embraced this digital revolution, with nearly every company now maintaining dedicated tech departments to manage their digital infrastructure, data security, and technological innovations. We're witnessing groundbreaking developments in artificial intelligence, robotics, and automation across industries. As our world becomes increasingly digital, understanding computer science isn't just beneficial - it's becoming essential for navigating modern life, career opportunities, and future innovations. Whether you're interested in healthcare, entertainment, business, or any other field, computer science knowledge can enhance your capabilities and open new doors.

In the symphony of technological evolution, computer science isn't just a note - it's the conductor orchestrating our future. As Arthur C. Clarke once said, 'Any sufficiently advanced technology is indistinguishable from magic.' Today's magic is tomorrow's routine, and understanding computer science is your key to being part of this extraordinary journey.

The Social Slot Machine

  “There are only two industries that call their customers ‘users’ - illegal drugs and social media” -Edward Tufte (American statistician and Professor at Yale University) Ever had that tingling, unbearably irresistible feeling of grabbing your phone and scrolling through every single media outlet that is possibly available at your fingertips? We see flashing icons before us Google, Facebook, Instagram, Snapchat, Tumblr, Pinterest, Reddit, Youtube, Tiktok, Whatsapp, Telegram, Twitter, Threads, Quora ... .okay I’m out of breath now. These flashing icons all offer us something our brain craves the most, information. We often look at information as a boring article that no one wants to read in a newspaper but really information is all around us and we consume it voraciously every day.  Consider the analogy for a second that likens our brain to a data processing machine. A machine that can process images, sounds, taste, touch and smells and produce something meaningful out of it. ...

Introduction to TechTok

Introduction We begin this blog by asking a simple question, what is technology. If we pose this question to you, our readers, we are sure you would know what it is but wait, question yourself again. Do you really know what it is? According to Webster's definition of technology- technology is the practical application of knowledge in any field and the capability that is produced through this application. We have a different answer to give you. Technology, in our humble opinion is a process, a journey of a hundred miles that began when our ancestors stepped out of their little caves and created fire.  In this world, in the world that we know, technology has become irreplaceable with our existence. We are defined by the car that we drive, the computer that we own and the company that we work and all of these are some by-products of the technological revolutions we have faced or are currently undergoing. It motors past us but we rarely stop to look and think, as the great inventors of...

The Zero IQ Machine That Rules Our World

The Computer Was Born to Solve Problems That Didn’t Exist Before — Bill Gates At first glance, you might wonder—what exactly are we talking about? A computer? A calculator? The machines we rely on to solve our problems effortlessly? We often think of computers as intelligent problem solvers, but in reality, they have zero IQ . Why? Because they don’t think for themselves. They simply follow instructions— our instructions . Take a simple math operation: if you input 1 + 2 × 3 , it returns 7 . But if you actually meant (1 + 2) × 3 , which equals 9 , the computer won’t correct you. It doesn’t “understand” the problem—it just executes exactly what it’s programmed to do. Ironically, this lack of independent thinking is what makes computers so powerful. They don’t get distracted, make emotional decisions, or second-guess. They process vast amounts of data in fractions of a second—something that would take humans years. That’s why, despite being "brain-dead," computers dominate indu...
