Recently, there is discussion about pendulum wave effect produced using the Newton's cradle. There are many YouTube videos about pendulum waves. Having seen some of these "amazing" wave effect, I thought that VRMath2 Editor should be able to produce a fake, but good enough to show the effect of pendulum wave simulation. And here you go, see the 3D simulation below.

## Sea simulation

In junior high school maths, there are usually questions about measuring the angle of depression and/or distance using trigonometry. Common examples could be like "Find the angle of depression from a lighthouse beacon 112 m above the sea level to a boat that is at a horizontal distance of 1.5 km from the lighthouse". A picture (not to scale) may be given as the one on the right. But then, what if the scenario is in 3D?

## A boat with a sail

A classic boat has a main body (hull) and a mast with a main sail. Using the build-in primative objects, there could be some possible boats contructed. In this blog, I used three objects: a SNOUT for the hull, a CYLINDER for the mast, and a 2D PIE for the sail. Of course these objects are scaled and textured with materials and images to be looking like (I hope ) .

## Potassium Hydroxide Molecule by Patrick Schachtner

Potassium Hydroxide

By Patrick Schachtner

Atoms are the building blocks of everything. Atoms can be divided into 118 different elements. Potassium Hydroxide (KOH) is a combination of the elements of potassium, hydrogen and oxygen. Potassium Hydroxide, more commonly known as caustic potash, is a corrosive oxidiser which is found when sodium hydroxide (NaOH) reacts with potassium. It is mainly used as a fertiliser because of its water retaining properties. Potassium hydroxide is a common substance with many sources found around the world.

## Ethanol Molecule

Atoms are the building blocks of all matter in the universe. They make up every object, material and substance. Atoms are made from protons, neutrons and electrons, and in different arrangements and quantities, form different atoms. 2 or more of these atoms can be grouped together to form molecules. Molecules are the smallest particles in chemical elements. An example of a compound is ethanol. This blog is written to show the molecule I have constructed, which is ethanol, and to explain its structure and characteristics. Also, I will share my experience creating the molecule, and what difficulties and questions I had about the creation process on VRmath2.0.
