The Sun and Earth model

Submitted by Andy on Tue, 20/11/2018 - 13:47

Most of us may know that the distance between the Sun and the Earth is one AU (Astronomical Unit: 150,000,000 km). However, due to the various online solar system images, many of us are not clear about how the Earth and Sun look like in space in the actaul scale. The VRMath2 Editor is a 3D modelling application, and is capable of modelling our solar system. Therefore, I did an experiment in modelling the Earth and Sun using actual parameters. The results are not as good as I expected, but they do make me appreciate the awe of the solar system, and the difficulties in modelling and comprehending the science of our solar system.

A pot of plant

It is hot summer (in Australia), plants and grass are quite stressed with dry and heat condition. Some succullent plants can survive easier, and I happen to see a pot of Snake plant, and think that I can create a 3D version of it.

Programming Driven 3D Modeling on the Web

Web3D2017

This is my presentation in Web3D 2017 Conference on 5th June 2017. The presentation is about my paper titled "Programming Driven 3D Modeling on the Web", which can be downloaded from ACM Digital Library, or from the Publication section in this website. In this paper, I am introducing this VRMath2 application, which incorporates a programmatic approach to create online 3D models and virtual worlds. This programmatic approach of generating online 3D models is conducive to learning in science, technology, engineering, and mathematics (STEM).

Newton's cradle twist

Newton's Cradle

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.

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

Ethanol is a molecule containing a mere 9 atoms of which there are 3 different atoms and has been known to human long prior to the advent of modern chemistry.

Ethanol

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.

Quartz molecule

All matter in the world is compounded from basic units of measurements called atoms. Atoms are made up of protons and neutrons, making the nucleus in the centre and electrons, which are much lighter in rings around it. Elements are substances made from only one type of atom, although when different atoms combine, they form compounds, or molecules. In a compound the atoms are being held together with chemical bonds. In this blog, I will be talking about the structure and characteristics of the molecule quartz.

Aluminium

Submitted by lxu7 on Fri, 29/07/2016 - 03:48

Introduction

Aluminium is the 13th element of the periodic table and has the atomic symbol of Al. It was first discovered in 1825 in Denmark by Christian Oersted (Winter, 2016). Aluminium is the most abundant metal in the earth's crust; however it is never found free in nature (Pappas, 2014). All aluminium that is used on earth comes from compounds as aluminium combines with other elements. Aluminium is very useful and can be seen from our everyday lives to large industrial uses. For example aluminium can be used in the form of foil to keep your sandwich fresh to building airplanes and jet engines. It is widely used due to the fact that it is plentiful, relatively inexpensive, strong yet lightweight, can combine with other materials easily, is resistant to heat and corrosion and a good conductor of electricity (Woodford, 2016).

Introduction

Methane. (Science: chemistry) A light, colourless, hydrocarbon which is toxic by both inhalation and skin exposure. Also infamously known for being the main substance found in flatulence (the bodily function is actually made up of 59% nitrogen and 21% hydrogen, just saying.) Nevertheless, this blog will explore the structure, composition and characteristics of Methane. Methane contains carbon and hydrogen in the ratio of 1:4 respectively. Since methane is both a powerful greenhouse gas and the simplest and most effective hydrocarbon. It is the main gas found in natural gas piped for use in homes, used to generate electricity and is even used as rocket fuel.
