A 110 million-year-old fossil of Cleoniceras ammonite, found in Madagascar. Ammonites are extinct cephalopods that lived in shells. Their closest modern relatives are nautiluses, octopi, squid, and cuttlefish. Like the nautilus, ammonites gradually added onto their shell to accommodate their increasing body mass. As they extended the shell they built a wall behind them, closing up the now too-narrow portion of the shell as they moved into the larger portion of the spiral.

Unlike the nautilus, the morphology of the tissue wall ammonites built between the chambers is not just a smooth curved wall. Instead it has a bizarrely complex 3-dimensional fractal shape. These are called “suture patterns” and mark the intersection of the septum walls with the shell. Scientists can’t agree why these walls are so complexly furrowed or even how they formed.

In the waters of purity, I melted like salt
Neither blasphemy, nor faith, nor conviction, nor doubt remained.
In the center of my heart a star has appeared
And all the seven heavens have become lost in it.

— Rumi (via sublimesea)

Sometimes we speak clumsily and create internal knots in others. Then we say, “I was just telling the truth.” It may be the truth, but if our way of speaking causes unnecessary suffering, it is not Right Speech. The truth must be presented in ways that others can accept. Words that damage or destroy are not Right Speech. Before you speak, understand the person you are speaking to. Consider each word carefully before you say anything, so that your speech is “Right” in both form and content.

— Thich Nhat Hanh (via painting-a-picture)
