Simulating Nature

Simulations for science education have been around for decades. Traditionally, the coding skills required were just out of reach for beginning students. Not so anymore. Using elementary javascript, we can code basic to advanced sims that show interesting science without having to spend years learning software development.

Books are great. There's no denying that. However, so are motion graphics! We can make abstract science concepts visual by coding up simple simulations. Our forthcoming science.js library will make it easy for students and coders everywhere to build their own sims.

• Expanding Universe Demo

If you participated in a general astronomy class at any point in the last 30 years, it’s likely you were shown a classic demonstration of how in our expanding universe, there is no central point from which everything else is receding. In fact, no matter where you are, on earth,...

• The True Nature of Accelerating Objects, in Code - Part II.

(If you missed part 1 of this discussion, the following won’t make a ton of sense. Read Part 1 here.) Recap: we’ve used a seemingly valid way to change the position and velocity of a moving particle. However, upon closer inspection, it turned out to not give physically realistic motion....

• The True Nature of Accelerating Objects, in Code - Part I

The first weeks of intro physics class focus on kinematics, or the study of motion. Chances are you came across an equation that looks like this: This equation, derived using integral calculus usually, gives the position as a function of time for a particle undergoing constant acceleration. If the object...

Many existing simulation collections suffer from the common blight of stagnation. They are built with old technology (flash or java applets) by old people (no offense intended, but programming is a young person's game!). The often look dated (like 90's video games), don't work on modern devices, and fail to communicate the fundamentals of the science to the students using them. These sims are fresh - built by students using modern javascript libraries. Sure, one day, they too will be old - but that day is not today!
