Mating Mandarin Fish (Synchiropus splendidus)
With their bright colours and mesmerising patterns, mating mandarin fish are quite a sight to behold. The pair hold the position in mid water, releasing their gametes, before retreating back to their coral hide out.

Truth Behind the Quote
Since I knew at some point people would remove the commentary (you know cause screw real sources!) from the image where I added it I decided to give it its own post here on my page so people can refer to it whenever they need to. I know somewhere down the line there’s going to be some shmuck that will end up removing the commentary on this post as well, so I would love it if followers who are aware of this to keep the torch going and at the very least kindly inform those who misquote this wonderful piece of literature of who the credit actually belongs to.
I cringe every time I see this quote along with Galileo’s name or picture accompanied by it with a gajillion notes.
As much as I love Galileo and the work he did put out, these are not his words. This line is an excerpt from “The Old Astronomer”, or “The Old Astronomer to His Pupil” written solely by poet Sarah Williams (1837–1868).
I love poems as much as the next person, even more so when it expresses the night and stars so creatively, but there’s already enough wrongfully cited publishing done by women attributed to the men of history.. Let’s at the very least give her credit for what she did and quit dedicating artwork, doodles, t-shirts, paintings towards the wrong person.
If you approached the rim of a volcano and looked down into it, you might expect to see a lava pool, but if the volcano previously erupted and then the top of it collapsed into a huge bowl-shaped crater, or caldera, then what you might see when you peer over the rim is a beautiful crater lake. Sometimes the water is acidic and the lake has a bright greenish hue. Other times the water is a cloudy turquoise color, yet other times the lake may appear to be a very deep shade of blue. Crater Lake, Oregon, is one of the most well known, but crater lakes can be found all over the globe. If the volcano has been dormant for a long time, the water can be extremely clear because no river or streams flow into with sediment deposits. In some cases, water may have filled up an impact crater to form a lake, but this is less common. A few crater lakes were created by man via an atomic blast, but an artificially-created crater lake is the least common of all. All crater lakes were once a place where the earth experienced great violence, but now are a place of great beauty … even though the volcano can become active and violent again.

The Phylogenetic ’Tree of Life’
Charles Darwin proposed that phylogeny, the evolutionary relatedness among species through time, was expressible as a metaphor he termed the Tree of Life. The modern development of this idea is called the Phylogenetic tree.
I think it’s incredibly important to cultivate children’s interest in science. That’s why I was so excited when I found this awesome physics experiment on io9!
We all love that famous movie tagline, but it can be tough for kids to understand. Here’s a basic experiment you can do with…
Gallium is a silvery metal with atomic number 31. It’s used in semiconductors and LEDs, but the cool thing about it is its melting point, which is only about 85 degrees Fahrenheit. If you hold a solid gallium crystal in your hand, your body heat will cause it to slowly melt into a silvery metallic puddle. Pour it into a dish, and it freezes back into a solid.
While you probably shouldn’t lick your fingers after playing with it, gallium isn’t toxic and won’t make you crazy like mercury does. And if you get tired of it, you can melt it onto glass and make yourself a mirror.
Someone get me this for my non-birthday.
