Scientists attached a video camera to Humboldt squid in order to observe how they use their color-changing skin cells in the wild.
Analysis of the footage revealed that the squid repeatedly flash red in the presence of other Humboldt squid, possibly as a way of communicating — though what, scientists aren’t yet sure. When close to the surface, the squids’ chromatophores flicker, giving their skin a hue of sunlight shining through the water column — possibly as a form of camouflage.

Each trig function in terms of the other five: color coded. Idk I’m just playin’ around in LaTeX and thought this table on Wikipedia would be worth color coding on its own so I made this little ditty. The reciprocal functions are the lighter colors of their regular trig counterparts. I wouldn’t call this a final version, but, hey, it’s pretty cute. High five for pattern recognition.

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.

There is a Diamond ExoPlanet and it’s worth is $26.9 Nonillion.
If we stacked all that money in $50 notes, this would be the outcome. The earth(on the left at the bottom) is used for size comparison.

The straight up physics of deformation at high speeds is fascinating. Although what is also fascinating is the one thing we really take for granted. TIME. The high frames per SECOND is the only thing that makes this possible to view.
This is a visual example of what happens when you can see TIME, AND physics. I think we forget how important time is in our lives, yet it’s one of the most fascinating. Without time you have no-thing.
