Science Art: Oral Cavity and Paranasal Sinuses - Coronal View exhibit, from Our Body: The Universe Within

Sinuses spiraling behind a bygone nose.

Someone went to the museum today. This has always been one of my favorite bits of human anatomy, the spirals inside our sinuses. Evolutionarily, they say they’re there to expose more wet membranes to the air, sticking to all the dust and pollen and stuff that would otherwise go into our lungs (and, incidentally, leaving those of us more sensitive to dust and pollen and stuff vulnerable to runny noses and nasal congestion).

Still, it’s an elegant shape. We walk around wit…

SONG: Blood is Family

SONG: “Blood is Family”.

Science Art: "Various Forms of Trachelomonas" (detail of "INFUSORIA"), 1883


Aren’t they the cutest little things?

These are kinds of Euglena, the weird little microscopic critters that are animals with plant-like characteristics – some of them can photosynthesize, despite swimming around with whip-like tails. The Trachelomonas also have hard shells, making them a little harder for less sunshiny critters to swallow.

This snapshot is from The Micrographic Dictionary; a guide to the examination and investigation of the structure and nature of microscopic object…

This might look like a jet plane’s engine, but it’s really a thing to test jet planes – supersonic ones. It’s a really big fan (with wooden blades!) inside a wind tunnel at Langley Research Center.

Big wind from an old Sitka spruce.

The picture’s from NASA in The Commons.

Science Art: Schéma de montage d'un turbopropulseur by Nerijp


This is a turbine – a “turbopropulseur” – used as an example of a “réducteur” – a reducing gear. The one end spins a lot more than the other end thanks to all the gears. Means a motor can make a propeller go around really fast… as long as it’s strong enough.

That’s the secret of the turboprop.
