Version 0.3.3, better rendering and electromagnetism


In this release I’ve written a faster rendering function that use in a more logical way OpenGl , so that’s possible to draw tons of particles in a very fast way. For showing this characterises  try the demo fountain that simulate a model of 250’000 particles (or watch the video above).

As second I’ve added the electromagnetic files force, and I’ve improved the electromagnetism support, so now you can simulate also some electromagnetic system like cathodic tube or valves. Watch the demo elmag_field that simulate positive and negative charged particles in an electromagnetic filed (type v for plotting the vector fields).

And the last new is the possibility to plot the vector field, if required.

Chemistry That Mattered

Call Me Stormy

Chemistry is the study of matter — stuff and how it interacts with other stuff. Even though chemistry doesn’t make a lot of news these days, chemists are making discoveries that change lives all the time. If the SciShow‘s Hank Green had to narrow down all of chemistry’s flashes of brilliance into the most awesome experiments in history, he would narrow it down to these three.

Scientific Ice Cream

Molecular Gastronomy

“It’s NEVER too cold for ice cream.” -Anonymous

Have you ever wondered how making ice cream the old-fashioned way actually works? Well, let’s say one night, you put both a water bottle and a container of vanilla ice cream in the freezer. The next day, when you open the freezer, the water bottle is frozen and rock-hard. But what about the ice cream? Why does the ice cream remain solid-like but still slightly soft? This is because ice cream has a lower freezing point than water. Ice cream contains many particles, which makes it harder for the water molecules in the ice cream to push the particles out of their way and become solid to form ice. The lowering of the freezing point of a liquid by adding compounds to it is known as freezing point depression. This is exactly what occurs in the process of making ice cream!
