Some fantastic mathematical illustrations, via wnycradiolab:
Kasia Jackowska’s Drawing Mathematics series whimsically illustrates various mathematical concepts as part of a project done for a brochure published by the University of Warsaw. Simple and sweet, these drawings add creativity to convention, using principles and formulas as her inspiration, and stylized animals as her muses. Can you recognize all the concepts?

I can pick out Sierpinski triangles and the Pythagorean theorem. What else do you see?
We only need to look at our own bodies to discover mysterious monsters and amazing creatures—if one can agree that such things sometimes come in very small packages. In case you didn’t know, you are a minority in your own skin. You are a walking ecosystem of immense complexity and diversity. So much so, that the space occupied by your body is less “you” and more “other creatures.” By this I mean that some ten trillion cells are “yours” in the sense that they contain your DNA, but there are more than one hundred trillion parasites, predators, freeloaders, and helpful cohabitants that…
My message to young students is to study your passion and work towards your dreams and goals no matter what gets in your way.

I’ve got your back, Kiera. No one deserves to be punished for honest curiosity.
Besides, if my teachers knew what I burned in the fume hood when they weren’t looking back during that semester of my senior year that I student-managed the chem lab? No comment …
Return of the Cicadas!
What a video! I’m pretty sure there will be only two reactions: “F-ing gross!!” or “F-ing cool!!”
With soil temperatures along the East Coast now above the mid-60’s, the Brood II cicadas are up and chirping! Check out WNYC/Radiolab’s real-time Cicada Tracker map to see where they have been observed:
The video above is a jaw-droppingly superb look at the rise of the magicicada from its underground lair, their mass ascent to the trees, their monstrous metamorphosis into adults, and their brief mission to avoid being eaten and reproduce.
More cicada stuff:
- Why do these periodic cicadas only pop up ever 13 or 17 years (depending ont he exact brood)? I was a guest on New Hampshire public radio to talk about the evolutionary advantage of prime numbers and enormous populations.
- Illustrated cicada emergence in GIF form!
- Time-lapse video of a Brood XIX cicada emerging
If any of you on the East Coast have photos or video of abandoned shells, climbing juveniles, or chirping adults, I’d love to see them! Tweet me or email them to itsokaytobesmart at gmail dot com.
To become a butterfly, a caterpillar first digests itself. But certain groups of cells survive, turning the soup into eyes, wings, antennae and other adult structures
That’s some metamorphosis!

The lateral line is a system of sense organs found in many fish, and is visible as horizontal line running across its body. The line senses mechanical changes in the surrounding water, such as changing water pressures. In some species, electrical impulses can also be detected.
The lateral line plays an important role in schooling behaviour, predation and orientation. For example, a predatory fish may use it to sense water vortices created by fleeing prey. Conversely, the changing water pressures from approaching predator can warn a prey fish.
In an experiment, individuals of a group of Pollachius virens (pictured) were removed and subjected to different procedures, and their ability to rejoin the school observed. Those that were blinded were able to rejoin to reintegrate into the school, whereas those which had their lateral lines severed were unable to do so.
