Modelling Quantum Entanglement


The polarization of the photon refers to the “direction” of the axis of the energy field, with the magnetic axis being offset by 90°. Polarization can be a direction like up or down, left or right. Polarization can also mean spin in a clockwise or counter-clockwise direction. The axis of the electric field may be rotating or spinning in time and […]

Modelling “Spooky Actions at a Distance”


A photon travels through the air as if it had a specific axis of spin called polarization. We know this is true because certain crystals will send photons in different directions depending on their polarization. By detecting which way the photon went, we know something about the polarization of the photon. Researchers at the National Institute of Standards and Technology […]

Lessons Learned from Gravity Animations


This entry is about programming computer animations based on the laws of physics. Gravity is probably one of the easiest and most fun computer animations to work on. Set a bunch of objects in motion and see what happens. Maybe add in a size for the objects and get some crashes, or add some walls and see these things bounce around, or… The animations […]

Adding Relativity to Gravity Animations


My last entry dealt with lessons learned while building a gravity animation. The animation works just like frames in a movie. Between each frame, the gravitational force between objects is calculated displayed on the screen as “Force”. This force is added to the current motion (momentum) of the object. The motion is added to the prior location of the object to get the new location of the object. […]
