Science Art: Diagram to Show the Destination of the Arterial Arches in Man and Mammals. (Modified from Rathke. )

Scientific illustration of arterial arches, the blood vessels around the heart that look like a drawing of a heartClick to embiggen

This is an anatomical drawing of the blood vessels around the heart, but it’s odd to me how much it looks like a simple drawing of a heart, a Valentines heart, with wings. The colored vessels are permanent, the text says, and the diagram appeared in a chapter on development of the heart. Maybe the Valentines heart is a potential heart, a heart not yet made. Or maybe it’s just wishful thinking.

I found this in Quain’s Anatomy (1898) on

Happy Easter to tho…

Science Art: Owen Magnetic Radiator Emblem

From 1915 to 1922, this was the symbol of electric luxury – or at least a hybrid-electric luxury car. The Owen Magnetic label was a celebrated icon of the finer things, and the electric vehicle was advertised as “The Car of a Thousand Speeds.” The more affordable Model-T was what established the gasoline combustion engine as the standard for automotive design, and after the Baker Electric enginemakers switched to war goods production, the company had to reorganize, and then went out of busin…

This is how public health was handled in the days before a lot of diseases were considered “eradicated.” It’s from The Body and Health: Grade Six by Ruby M. Simpson, a school book for Canadian children, which I found on

I try to keep my pandemic-related posting to a minimum – I figure there’s enough of that elsewhere in the media right now – but today, my son started coughing and has a sore throat. Oh, great.

This textbook explains what a real quarantine …

NASA named the landing site for the Mars rover mission after science fiction author Octavia E. Butler.

As they say on their Image Gallery site:

The landing location is marked with a star in this image from the High Resolution Imaging Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter (MRO).

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will character…

Science Art: Persea: Taft, by Royal Charles Steadman, 1914.

Scientific Illustration of a Taft avocado, from the USDA Pomological Watercolors Click to embiggen

It’s an avocado, an aguacate, also known as an alligator pear in English and a “lawyer pear” in Dutch. This is a Taft variety, an ancestor of the Lula cultivar, and may or may not still be around. In the 1910s, it was a well-known summer variety of the “Guatemalan race” of avocados. There are three races of avocados, did you know? The one you probably find in your grocery, the Hass, is a cross between Guatemalan and Mexican races probably. No one’s really sure because the fi…
