Time dilation isn't an approximation or a thought experiment — it's measured every day, in GPS satellites, particle accelerators, and atomic clocks on aeroplanes.
This deep-dive interactive module explains exactly why it happens from first principles: watch the light clock animation show how a moving clock's light pulse takes a longer path, making every tick genuinely slower. Explore the full Lorentz factor curve, solve the twin paradox step by step, and see three real-world experiments that proved time dilation beyond any doubt — GPS corrections, muon survival, and the 1971 Hafele-Keating flight experiment.
Includes a complete Theory section with the γ reference table, proper time explained clearly, and why the effect is real — not an illusion — plus a 5-question Quiz with numerical problems.

Special relativity isn't just a theory — it's the reason GPS works, why muons reach the Earth's surface, and why E = mc² powers every nuclear reactor on the planet.
This interactive module makes it tangible: drag the speed slider toward c and watch two animated clocks diverge in real time on the Time Dilation tab. See a spaceship compress along its direction of motion on Length Contraction. Plot the relativistic energy curve rising toward infinity as speed approaches c on E = mc². Then explore the Spacetime diagram to see how moving frames literally rotate through space and time.
Includes a complete Theory section with Einstein's two postulates, a Classical vs Relativistic comparison table, the twin paradox, and velocity addition — plus a 5-question Quiz with numerical problems. Built for Class 12 Physics and Modern Physics enthusiasts.

Three types of nuclear radiation — three completely different particles, penetrations, charges, and dangers.

Switch to the Penetration tab and see all three beams simultaneously stopped by different barriers. In the Deflection tab, watch alpha bend toward the negative plate, beta bend sharply toward the positive plate, and gamma pass straight through — all animated live in an electric field.

Nuclear fission is the most powerful energy source humanity has ever harnessed — and it all starts with a single slow neutron hitting a uranium nucleus.
This interactive module takes you through every layer: fire a neutron and watch ²³⁵U split into Kr + Ba with an animated energy burst, then step through a chain reaction generation by generation and see exactly what k < 1, k = 1, and k > 1 look like in real time. Switch to the Reactor simulator and balance control rods and coolant flow to keep the core stable — or watch it go critical. Includes a complete Theory section with the fission equation, mass-energy equivalence, criticality table, and reactor component breakdown — plus a 5-question Quiz.

Half-life isn't just a formula — it's one of the most elegant laws in all of physics.
This interactive module lets you feel it: drag the sliders to reshape the decay curve in real time, step through an atom grid and watch individual nuclei decay by pure chance, and use the Carbon Dating calculator to find the age of real artefacts from the Shroud of Turin to Lascaux cave art. Includes a Theory section covering the decay law, mean life, activity, and a full isotope reference table — plus a 5-question Quiz with numerical problems.

Radioactive decay is one of the most important and most misunderstood, concepts in nuclear physics.
This interactive module breaks it down completely: watch animated alpha, beta, and gamma decay with live particle emission and penetration barriers, then switch to the Half-Life simulator to drag the sliders and see the exponential decay curve rebuild instantly. A complete Theory section covers all three decay equations, the full comparison table, and the decay law plus a 5-question Quiz to lock in your understanding before the exam.

Every element in the universe has a unique spectral fingerprint — a set of precise wavelengths of light it emits when its electrons jump between energy levels.
This interactive module lets you explore exactly how it works: select Hydrogen, Helium, Sodium, or Mercury, choose an electron transition, and watch the Bohr model animate in real time as a photon shoots out. Switch to the Spectra tab to see realistic emission line patterns and compare all four elements side by side.
