Have you ever wondered how the technology we use every day actually works? Let’s dive into the fascinating world of data and see how it all comes together. Imagine a grain of rice. It’s tiny, right? Now, think of it as a “byte,” a unit of digital information. Our computers use a language made up of 1s and 0s, called bits, to store and process data. Eight bits make a byte, and when you gather a thousand bytes, you get a kilobyte. Keep going, and a thousand kilobytes become a megabyte. Today, we often talk about gigabytes and terabytes, but do we really understand how big these numbers are? For example, a terabyte of seconds is equal to 32,000 years!
We’re moving into even larger data sizes, like petabytes. Just one petabyte could cover the entire island of Manhattan with data. Did you know that all the videos on YouTube add up to about 500 petabytes? Companies like Google store up to 10 exabytes of data. We’re collecting so much information that managing it is becoming a huge challenge.
Let’s take a step back in history. After the invention of the Gutenberg printing press, the number of books printed in 50 years was equal to what scribes had written in the previous 1,200 years. Today, the amount of information we have doubles every 2 to 3 years. In 2007, the total data saved worldwide was about 300 exabytes. By 2013, it had grown to 1,200 exabytes. That’s four times more data in just six years, and this rapid growth is expected to continue.
Consider the Square Kilometer Array, a group of radio telescopes that will produce an exabyte of astronomical data every four days. In the future, we might be dealing with zettabytes of data, which, if compared to our rice analogy, would fill the Pacific Ocean. This isn’t just about Moore’s Law, which talks about the rapid growth of computer power; it’s about BIG data. While much of this data might seem useless or hard to organize, its sheer volume could change how we live and understand the world in ways we can’t yet imagine.
Think about a cave painting. It took a long time to create and contained limited information. Now, compare that to a photograph, which is quicker to produce and holds much more detail. As we started capturing motion, our observations became more meaningful, but they also generated more data. Initially, this involved only 12 or 24 images, but as we increased resolution and divided experiences into smaller time frames and details, we ended up with a lot of data to manage.
Big data might even be part of our DNA. Sequencing the first human genome in 2001 cost about $3 billion. Today, the same process costs around $1,000, making it potentially cheaper to sequence a genome than to store it on traditional devices. Beyond processing and analyzing this vast amount of data, we face a practical problem: where will we store it all?
In 100 years, it’s estimated we’ll be storing 42 yottabytes of data each year. With current technology, we’d need enough data centers to cover the surface area of 12 Jupiters. However, DNA might offer a solution. Researchers at Harvard have successfully written entire books to DNA, which can hold petabytes of data in just a few grams. While we don’t yet know how we’ll read, write, or store it, finding solutions for this data explosion will require creativity and innovation.
This might redefine what it means to “save the world.” Stay curious and keep exploring!
Imagine the different data sizes as physical objects. Create a visual representation using everyday items to compare bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. For example, use grains of rice, cups of water, or stacks of paper. Present your visualization to the class and explain how each item represents a different data size.
Research and create a timeline that shows the growth of data from the invention of the Gutenberg printing press to the present day. Include key milestones such as the introduction of the internet, social media, and big data technologies. Share your timeline with the class and discuss how these events have contributed to the explosion of information.
Reflect on how data impacts your daily life. Keep a journal for a week, noting every time you interact with data, such as using social media, streaming videos, or browsing the internet. At the end of the week, analyze your journal entries and write a short essay on the role of data in your life and its potential future impact.
Conduct a simple experiment to understand DNA data storage. Use colored beads to represent the four DNA bases (A, T, C, G) and create a “DNA strand” that encodes a short message or piece of data. Present your DNA strand to the class and explain how DNA can be used to store vast amounts of data in a compact form.
Participate in a class debate on potential solutions for managing the future explosion of data. Research different technologies and approaches, such as cloud storage, quantum computing, or DNA data storage. Present your arguments for or against these solutions and engage in a discussion with your classmates about the most viable options for the future.

[MUSIC] We all use technology, but do we understand how it works? Consider a grain of rice. It’s not much of a bite, but imagine if it were a byte. Our computers operate using a language of 1s and 0s to store information and compute instructions. Eight of these bits make a byte, and a thousand bytes make a kilobyte, while a thousand kilobytes make a megabyte. Today, we commonly deal in even larger units, like gigabytes and terabytes, although we may not fully grasp how vast these quantities are. For perspective, a terabyte of seconds equals 32,000 years!
We are rapidly moving beyond these scales to even larger ones, such as petabytes, with just one petabyte being able to cover the entire island of Manhattan. Did you know that all the videos on YouTube amount to about 500 petabytes? Companies like Google store up to 10 exabytes of data. We are accumulating so much information that it’s becoming a significant challenge to manage it.
[MUSIC] It’s estimated that the number of books printed in the first 50 years after the Gutenberg printing press equals the total written by scribes in the previous 1,200 years. Today, we double our store of information every 2 to 3 years. For instance, in 2007, the total data saved globally was estimated at 300 exabytes. By 2013, that number had grown to 1,200 exabytes. The total amount of data on Earth has quadrupled in just six years, and this acceleration is expected to continue.
The radio telescopes that comprise the Square Kilometer Array will generate an exabyte of astronomical data every four days. In the coming years, we may live in a world that deals in zettabytes, one of which, on our rice scale, would fill the Pacific Ocean. This discussion isn’t just about Moore’s Law, which pertains to the exponential growth of computing hardware power; it’s about data: BIG data. While much of this data may be useless or difficult to organize, its sheer volume will likely lead to changes in how we live and understand our world, possibly in ways we cannot yet imagine.
Consider this cave painting. Its creation was slow and contained limited information. In contrast, a photograph is faster to produce and holds much more detail. As we captured motion, our observations became more meaningful, but they also generated more data. Initially, it involved only 12 or 24 images, but as we increase resolution and divide experiences into smaller time frames and details, we end up with a substantial amount of data to manage.
Perhaps big data is ingrained in our DNA. Sequencing the first human genome in 2001 cost roughly $3 billion. Today, the same sequencing can be done for about $1,000, making it potentially cheaper to sequence a genome than to store it on traditional storage devices. Beyond the challenges of processing and analyzing this vast amount of data, we face a practical problem: where will we store it all?
In 100 years, it’s estimated we’ll be storing 42 yottabytes of data annually. Using current technology, we would need enough data centers to cover the surface area of 12 Jupiters. However, DNA itself might provide a solution. Researchers at Harvard have successfully written entire books to DNA, which has the potential to hold petabytes of data in just a few grams of genetic material. While this doesn’t clarify how we’ll read, write, or store it, addressing the impending data deluge will require innovative solutions.
This might redefine the concept of “saving the world.” Stay curious.
