Particles Live Wallpaper

Fond d'écran en direct de simulation de particules subatomiques.

This is a live wallpaper that simulates the dance of subatomic particles such as electrons, protons, and neutrons. If left alone, the particles will coalesce into atoms, which you can then break apart again with your fingers 👆.

Details for the nerds...

Particles

Protons, neutrons, electrons, positrons, neutrinos, and gamma rays (purple ripples).

Forces

Electromagnetic, strong nuclear, weak nuclear, and finger 👆.

Phenomena

Nucleosynthesis 💥

The strong nuclear force pulls protons and neutrons together to form nuclei.

Nuclear drip line 💧

Isotopes that are stable in real life are also stable here. Unstable isotopes undergo the correct form of decay to become a stable isotope.

Beta- decay

The weak nuclear force causes a free neutron or a neutron in a neutron-rich nucleus to turn into a proton while emitting an electron and a neutrino.

Beta+ decay

Conversely, a proton in a proton-rich nucleus will turn into a neutron while emitting a positron and a neutrino.

Electron-positron annihilation 🌈

When a positron collides with an electron, they annihilate and emit two gamma rays.

Proton-proton chain reaction 🌞

As the atoms fuse, you may observe a chain reaction similar to what happens in the Sun as hydrogen fuses into helium.

Other features

• Interactivity: As you use your device, your finger 👆 will nullify the strong nuclear force and emit a positive charge, breaking apart nuclei and attracting electrons.

• Nuclei labeling: Nuclei are labeled with their element symbol and nuclear mass.

• Battery level visualization 🔋: As your device's battery goes down, the simulation slows down.

• Charging visualization 🔌: If your device is charging, the simulation speeds up significantly.

Unrealisms

• Relative particle masses and sizes and force strengths are tuned for visuals, not realism.

• Very limited quantum mechanics (gamma ray waves only).

• Alpha decay doesn't exist without quantum mechanics.

• Electron orbitals don't exist without quantum mechanics.

• Chemical bonding doesn't exist without orbitals.

• Momentum but not energy is conserved during beta decay.

• Particles undergo inelastic collisions with the edges of the screen, so that total energy slowly declines, allowing for heavier elements to form.
