Alloys: Bronze

Given that there are many different types of bronze with a wide variety of elements included, the alloy cannot be defined as having one set composition. Though the most well known bronze is likely the common copper-tin alloy, alloys such as bismuth bronze, silicon bronze, and aluminum bronze don’t necessarily contain tin.

That being said, the most well known bronze alloy, and the one most people probably think of when they hear the word, is composed of mostly copper with tin or arsenic and, potentially, small amounts of other elements. The oldest tin-copper bronze alloys found are from around 4500 B.C., and this replacement of stone tools with bronze eventually led to the Bronze Age. (The Bronze Age eventually gave way to the Iron Age, because, despite bronze’s favorable properties, iron is more plentiful and easier to find.)

The addition of tin, arsenic, and other elements produces a harder material than copper alone. Bronze also has the favorable properties of being corrosion resistant, non-magnetic, has excellent heat transfer properties, is relatively easy to machine, withstands high temperatures, and is resistant to wear and friction. Unlike steel, bronze does not spark when struck and is therefore useful as tools in environments containing flammable vapors. 

Some historical applications of bronze include in statues, weapons and tools, and currency/coinage. The alloys is also well known for is usage in musical instruments, often bells and cymbals, as well as the windings of string instruments such as the guitar and piano.

Fluid

Interactive webtoy by David Li is a fun fluid dynamics simulator which lets you play around with various parameters - here is a video of it in action:

Fluid simulation is a GPU implementation of the FLIP method (with various additions). Particle rendering uses spherical ambient occlusion volumes.

Modified Stems: Thorn

Thorns are modified branches or stems. Thorns and spines are derived from shoots and leaves respectively, and have vascular bundles inside, whereas prickles (like rose prickles) do not have vascular bundles inside. The tree shown in the picture above is called the honey locust tree, also known as the thorny locust. Just look at those thorns!
