What is Computer Science?
SMARTe Interactive Books
Lily loved to explore and learn new things, but she had never heard about computer science before. One sunny day, as she was playing in her room, she decided to ask her AI about this. "Hi, Robbi! What is computer science?" Robbi smiled and explained, "Computer science is like magic for machines, Lily. It's all about understanding how computers and technology work. Just like you learn math and science in school, computer science helps you understand the language of computers and how they do incredible things."
What are Stars Made Of?
Lily's adventure started when she asked her wise grandfather, Grandpa Joe, about stars. He explained that stars are giant balls of hot, glowing gas. They are made up of different elements, such as hydrogen and helium, which are the universe's building blocks. The incredible heat and pressure inside a star make it shine brightly like a dazzling diamond in the night sky.
The Most Important Stars Lily was curious to know which stars were the most important. Grandpa Joe told her that all stars have their significance, but some are more famous than others. One such star is our very own Sun, which is responsible for giving us light and warmth. It is the closest star to us and provides energy for all living things on Earth.
There are other stars called "supernovas" that shine brilliantly for a short time before exploding. These explosions are so powerful that they can outshine the entire galaxy. They create new elements and spread them across the universe, helping to form new stars and planets.
Lily looked up at the stars with wonder as the night deepened. She now understood that stars are magnificent balls of hot gas, each with its own story to tell. From the powerful Sun to the explosive supernovas and the captivating constellations, the stars were a gateway to a world of mysteries waiting to be explored.

A supernova
A star is a massive ball of plasma held together by gravity. It radiates energy because of the nuclear reactions inside it. It radiates heat, light, and every other part of the electromagnetic spectrum, such as radio waves, microwaves, X-rays, gamma-rays, and ultraviolet radiation. The proportions vary according to the mass and age of the star.
