By Sang Heon Park, from the App Store
Description by Sang Heon Park Written by the developer, not by AppBrain. Click to read.
What if you ran close to the speed of light − would time really slow down?

The Relativity Tales is an interactive science story that lets you experience Einstein's special relativity with your fingertips, no equations required.
Play with the principles yourself, then step into stories where those very principles become the key.

■ Fingertips, not formulas
Run the thought experiments Einstein could only perform in his head, right on your screen.
Watch time flow differently for someone in motion, lengths shrink, and the very idea of "at the same time" fall apart before your eyes.

■ Stories where science is the plot
Every principle you experience becomes the key to a story.
· A courtroom thriller where the relativity of simultaneity cracks an impossible alibi
· An explorer's dream of reaching the edge of the universe, made possible by length contraction
· A moment where time seems to stand still, born from time dilation
The moment you understand the science, the story starts to look different.

■ Contents
Chapter 1. Lorentz Transformation − The invisible rules of spacetime
Chapter 2. Relativity of Simultaneity − When "simultaneous" falls apart
Chapter 3. A Story of Simultaneity − A spacetime-trick courtroom thriller
Chapter 4. Length Contraction − The secret of shrinking distance
Chapter 5. A Story of Length Contraction − An explorer's longing dream
Chapter 6. Time Dilation − Does time keep a different beat?
Chapter 7. A Story of Time Dilation − The moment time seemed to stop
Chapter 8. Lorentz Playground − Lorentz transformation, your way

■ Perfect for
- Science lovers who get a headache at the sight of equations
- Anyone who watches a sci-fi movie and wants to know the science behind it
- Anyone who's ever wondered, "So what IS relativity, anyway?"
- Parents who want to share the wonder of science with their kids
- Teachers looking for a great tool to show relativity in class

■ Good to know
The first 3 chapters are free to play. The remaining chapters can be unlocked with an in-app purchase.

Take the equations out of science, add a story, and what remains is wonder.
(science − equation + story = wonder)
