Horizon EDA is a free and open source electronic design automation package for printed circuit board design. It allows users to maintain and share a pool of parts, draw schematics, and design, 3D-preview and export PCB layouts for manufacturing. It runs on Linux and Windows.
KiCad is an open source PCB design and electronics CAD suite for Windows, macOS and Linux. It includes a schematic editor, a PCB editor and a 3D viewer, and is described as forever free. The schematic editor supports hierarchical designs and includes an integrated SPICE simulator and electrical rules checker. Documentation is written and maintained by a volunteer docs team.
A physics-based simulation of two independently driven pendulums that begin with nearly identical conditions. Users can adjust parameters and drag a pendulum to change its starting position; over time the two pendulums diverge, illustrating sensitivity to initial conditions in chaotic systems.
Sectional Anatomy is an educational resource for documentaries, courses, books, reference material, or self-learning.
Stat Trek provides free online tutorials and calculators covering statistics and probability. Tutorial topics include AP Statistics, probability, linear regression, ANOVA, survey sampling, and matrix algebra, explained in plain English. The site also offers practice exams and a random number generator and sample size calculator for statistical work.
Javalab is a site described in its title as covering science simulation, probeware and coding. Its pages include physics and biology simulations, such as a static electricity experiment, a lung model and a magnetic field around a coil.
An experiment that visualizes thousands of bird sounds using machine learning. The Essential Set for North America sounds are provided by the Macaulay Library, with support from the Cornell Lab of Ornithology. Built by Kyle McDonald, Manny Tan, Yotam Mann, and friends at Google Creative Lab, with open-source code available.
