1. On Monday, Programs manipulate and display data and information. Computers ultimately work with numbers, but words can be represented by numbers. High level computer programming languages translate words to and from numbers, so if you want to use words, you can usually do so without bothering with numbers. Most programmers will want to use both.

## Implications of Geological Phenomena

Large volcanic eruptions can temporarily affect global weather by placing considerable dust and greenhouse gasses in the air. The tectonic plate movement may be involved in the sequestration of carbon dioxide (Ward and Brownlee,  2000).

3. ## 3 Simulations

### Population Dynamics

Food webs can evolve over time, in cycles and permanently. Predator-prey relations are an example of changes in the components of the food web over time. For example, if the population of predators grows too much, then over predation will occur. Consequently, the population of the prey falls, and can no longer support such a large population of predators. The population of predators falls, resulting on less pressure on the prey population, which then recovers. This cycle can repeat itself many times, as expressed in the Lotka-Volterra Predatory-Prey model (shown below in a systems dynamics process). Such Predator-Prey cycles occur in human economies as well.

Click on the “Simul…” button to run the below simulation of the relation between a moose and wolf population where wolves prey on moose. Feel free to explore additional settings and options. You can even create your now account on the underlying Insightmaker platform and create your own simulations.

## Virtual Reality

Virtual Reality (VR) allows a user to view graphic content in three dimensions, and move about the graphics. Typically virtual reality provides stereographic capability, so the user feels depth perception. Oculus makes dedicated virtual reality goggles. Samsung makes a headset that can convert an Android phone into a VR headset.

VR can be even used on ordinary laptop, tablet and phone screens. Although the experience does not use stereoscopy to produce 3D effects, one can still explore in three dimensions.

For example, see the below example.
