📝 Quick summary of key information
How can letters and numbers explain the universe?
Letters and numbers are like the building blocks of our world. Letters are small symbols that come together to make words. For example, the letters A, B, C can be used to write words like cat, dog, or school. Numbers are symbols used to count and measure. For example, 1, 2, 3 help us know how many things there are or measure distances.
Letters are very important for reading and writing. They help us understand what is written in books, on road signs, or even on restaurant menus. For example, a sign with the letters S-T-O-P tells us to stop.
Numbers are very important too. They help us measure and count. For example, the numbers on a clock tell us what time it is. The numbers on a thermometer tell us if it is hot or cold. They are also used to count things, like apples in a basket.
Letters and numbers often work together to give us useful information. For example, a postal address uses letters for street names and numbers for house numbers. Learning letters and numbers is very important to understand the world around us and to succeed in school.

Einstein's Magic Formulas
How can letters and numbers explain the universe?
The Shiny Puzzle Carriage
After understanding the twin paradox (1) with the help of the magic turtle, Léo and Léa feel ready to explore new wonders. In the Puzzle (2) Room of the train, they discovered that time can pass differently for everyone. Thanks to Albert Einstein, they understood that speed affects the passage of years. Curious and excited, they now wonder how letters and numbers can explain the universe. Albert Einstein, with his mischievous smile, invites them to discover the magical formulas (3) that reveal the secrets of nature.
Not long after leaving the Puzzle Room, Léo and Léa enter a wagon filled with shiny puzzles. The walls are covered with glowing symbols and mysterious formulas. Léo, with his engineer's cap, carefully observes the puzzles. Léa, armed with her sketchbook, sketches the shapes and colors of the symbols.
Albert Einstein, with his mischievous smile, speaks to the children: « Each symbol represents a part of the laws (4) of nature. To activate the train's secret mechanisms, you must match these symbols correctly. »
Léo, eyes shining with curiosity, then asks:
« How do we do this? »
Léa, after looking at the puzzles, then asks:
« Where should we start? »
Albert Einstein, with a mischievous smile, says to them:
« Look at the puzzles carefully. You need to find the symbols that go together. Try to match them correctly. »
Together, they start solving the puzzles. By completing the games, they discover a hidden formula that shines in the sky and completes their Relativity (5) Map. A bright light illuminates the wagon, revealing fascinating secrets about the universe. They wonder what this formula will reveal to them.
Magic Math
After finding the hidden formula, a bright light fills the wagon. A soft and warm voice echoes. It's Albert Einstein talking to them.
Albert Einstein, with a big smile, exclaims:
« This formula is the famous formula of Albert Einstein. It shows the relationship between energy and mass. »
Léo, eyes sparkling with curiosity, asks:
« What does this mean? »
Léa, curious, asks:
« Why is this formula so important? »
Albert Einstein, with a big smile, explains: « With this formula, we can understand how energy and matter change. It explains powerful things (6) in the universe. »
The children listen carefully. They find out that math is a key to unlocking the mysteries of the universe. They feel more and more excited with each new discovery.
As Léo and Léa look at the Map of Relativity, the train gently slides under a sky full of shooting stars. Each wish makes a memory of past adventures shine. A little owl perched on a nearby tree guides them to a new question. Where do shooting stars come from and why do they shine in the sky? Léo and Léa, with their endless (7) curiosity, promise to find out during their next adventure on the Magic Train of Albert Einstein.
