What’s on the Special Relativity poster
The rule, 3 worked examples, and the mistake everyone makes.

- γ = 1/√(1 − v²/c²)
- v = 0.1c = γ ≈ 1.005
- v = 0.87c = γ = 2

The postulates are simple. Every counter-intuitive consequence is forced by keeping c constant for everyone.

- Who is the Special Relativity poster for?
- Special Relativity belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning relativity can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Special Relativity poster?
- The laws of physics are the same for all inertial observers, and c is the same for all of them. A wall chart earns its place by being glanceable from where the work is happening, so Special Relativity belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Special Relativity?
- Black Holes, Cosmology and General Relativity sit alongside Special Relativity in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Black HolesCosmologyGeneral Relativity
- Is the Special Relativity poster free to download and print?
- Yes. Special Relativity downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Special Relativity poster print at?
- Special Relativity is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Special Relativity loses nothing.Printing guide
