Nuclear reactions, phase transitions, heat transfer and planetary energy balance — explore the physics of energy at every scale.
This category covers thermodynamics, nuclear physics, statistical mechanics and renewable energy engineering through hands-on interactive models. You will learn how binding energy makes iron the most stable nucleus, how the Metropolis algorithm drives phase transitions in the Ising model, how Lennard-Jones forces govern molecular dynamics, and how radiative balance sets the temperature of a planet. Each Energy simulation runs entirely in your browser with adjustable parameters and live charts, so you can experiment freely and watch the physics respond in real time. These topics matter because they underpin power generation, climate modelling, materials science and clean-energy technology — the same equations engineers and physicists use every day to design reactors, wind farms and solar arrays.

From nuclear reactions to atmospheric balance — energy in every form
Energy and thermodynamics simulations reveal the fundamental laws that govern heat, work, and energy transformations. From nuclear binding energy curves that explain why iron is the most stable element, to chain reactions in fissile material, these models make abstract concepts tangible and interactive.
The Ising model demonstrates phase transitions using Metropolis Monte Carlo sampling — watch ferromagnetic domains form and dissolve as you change temperature past the critical point. Molecular dynamics with Lennard-Jones potentials let you observe how individual particles create macroscopic phenomena like pressure, temperature, and phase changes.
Climate science relies on energy balance models similar to those presented here. The Earth Energy Balance simulation shows how solar radiation, albedo, and greenhouse gases determine planetary temperature — the same physics behind real climate projections by IPCC models.

Common questions about this simulation category
Every Energy simulation on this page is a browser-based, interactive Energy model you can run instantly — no downloads, accounts or plugins required. Whether you want to learn Energy online for a school physics course, a university thermodynamics module or simply out of curiosity, these visual tools turn abstract equations into something you can see and adjust. A real-world application: the same energy-balance and renewable-power physics shown here helps engineers size solar arrays, optimise wind-turbine spacing and model grid stability, while the nuclear and statistical-mechanics models reflect the methods used in reactor design and climate research worldwide.
