Connections of Neuron (nervous system, neural network)

About this simulation This simulation allows you to connect and test various neurons. Inspired by logic circuits, we created three types of neurons: ‘AND’, ‘OR’, and ‘NOT’. In reality, human Interneurons(association neurons) are much more complexly … more

Polarization

Polarization

Polarizers are made of long-chained molecules which absorb light with electric fields. When you shine a light on a polarizer, only a part of the light is passed. The polarizing plate materials absorb only the electric … more
