Ernst Haeckel

Not only was Ernst a Haeckel of an artist, he was a brilliant biologist and naturalist as well. 

Side note: I have business cards, for some unknown reason, and there’s a Haeckel illustration on the back of each one.

Always reblog Ernst Haeckel.

Kate MccGwires Feather sculptures

Kate MccGwire’s feather sculptures are awe inspiring in their detail; they are the type of thing that is marveled. Gathering, peeling, and layering are just a few ways she constructs her work. The materials, vibrant colors, and tactile quality gives them an uncanny feeling.

QUARANTINE!

Though often used as a synonym of “isolation" (where sick people are kept from well people), quarantine is technically defined as “to separate those suspected of exposure to an illness to see if they become ill” - hence the quarantine laws for livestock and pets when moving between countries, especially countries where rabies or hoof-and-mouth disease isn’t endemic.

These signs were posted on houses and farms that had a patient (and, as such, exposed family or herd members) infected with, from top to bottom, hoof-and-mouth disease, scarlet fever, diphtheria, smallpox, and poliomyelitis.

The Natural Logarithm
Many things in nature come from logarithmic relationships. There is another kind of logarithm called the natural logarithm, and its symbol is ln (which stands for “logarithm natural”) instead of log.
The simple equation above results in a trace of a nautilus shell. In the equation r is “distance from center of the spiral” and θ is “revolutions around the center.” So the natural log of the radial distance determines the number of polar revolutions.
In each successive plot above, a new revolution has been added. Yet they maintain their appearance as the scale increases.

We want to create an index of the lady scientists on Tumblr, much like shychemist did for all scientists.  (Have we thanked you lately?!)  However, it’s a bit more challenging as not all of you announce your gender on your blogs.  So, if you identify as a woman/female,* let us know if you want to be included!

Signal boost! 

Numbers and letters are different symbol systems and we have totally been ignoring that in synaesthesia research, you guys.

Programs for Troubled Vets Don’t Work
SO HOW ABOUT ENDING WAR?
By John Horgan | February 22, 2014 | 
Cross-Check, Scientific American Blog Network

There is a shamefully broad gap between the lip service that we Americans give soldiers—or “heroes,” as we love to call them—and our actual treatment of them. 

The $125 million “Comprehensive Soldier Fitness” and other mental-health programs for U.S. troops have not been shown to work.

CUTTING TO THE BOTTOM LINE:

According to a report by Harvard’s Shorenstein Center,

  • more than 6,500 American soldiers have been killed;
  • more than 50,000 wounded since 9/11.
  • More than 1,700 soldiers have lost one or more limbs;
  • more than 250,000 have suffered a brain injury.

Post-9/11 U.S. wars cost as much as $6 trillion so far, money that could have helped improve health care, education and transportation in this country.

And let’s not forget the hundreds of thousands of Afghans and Iraqis killed or maimed under U.S. occupation.

The psychological suffering of U.S. veterans is just one symptom of a terrible disease afflicting our culture, the disease of militarism. The goal of psychologists—and all of us–should be to eradicate this scourge, not merely treat its symptoms.

Fair enough.

Aww man. Yesterday I went to the Hendrik Conscience historical library and I was finally able to lay my hands on a copy of Ernst Haechel’s Kunstformen der Natur. It was so wonderful. The book was restored, but that didn’t really matter, at least it didn’t fall apart while I was reading it haha.
What amazed me the most was the fact that this book had such a profound influence on the Art Nouveau movement. Not only the shapes of nature, but also Haeckel’s craving for symmetry, many a time made me like I was looking at vases and lampshades in stead. The middle picture shows a set of intresting looking animals, but they might have been the helmet collection of Queen Jadis (aka the White Witch of Narnia)!
All-in-all an awesome book. I wished Haeckel had made more books like these.

What I would give to line my walls and shelves with Haeckel’s art….

Waste Body Burden

'BODY BURDEN'  [source]
Toxic chemicals, both naturally occurring and man-made, often get into the human body. We may inhale them, swallow them in contaminated food or water, or in some cases, absorb them through skin. The term ” body burden ” refers to the total amount of these toxic chemicals that are present in a human body at a given point in time.  Sometimes it is also useful to consider the body burden of a specific, single chemical, like, for example, lead, mercury, or dioxin.

Some chemicals or their breakdown products (metabolites) lodge in our bodies for only a short while before being excreted, but continuous exposure to such chemicals can create a “persistent” body burden. … 

Other chemicals, however, are not readily excreted and can remain for years in our blood, adipose (fat) tissue, semen, muscle, bone, brain tissue, or other organs.  Whether chemicals are quickly passing through or are stored in our bodies, body burden testing can reveal to us an individual’s unique chemical load and can highlight the kinds of chemicals we are exposed to as we live out each day of our lives.

DÉCOLLETAGE
[noun]
the upper part of a woman’s torso, between her waist and neck, comprising her neck, shoulders, back and chest, that is exposed by the neckline of her clothing. However, the term is most commonly applied to a neckline that reveals or emphasizes cleavage.
Etymology: borrowing from French décolletage, from décolleter “to reveal the neck or neckline”. 
[John Singer Sargent - Portrait of Madame X]

My favorite painting meets one of my favorite words. Happy Friday!

Recently, girls across the United States applied for WISH, a program run by NASA which was offered to junior girls who hoped to pursue careers in STEM (Science, Technology, Engineering, and Math, a field in which women are a scathing minority.

However, today an email from NASA to the applicants canceled the program as a result of complaints from male high school students who demanded to participate as well. There is nothing wrong with men and women working together to create innovations and better the world, but with men holding 76% of the jobs in STEM and the stigma surrounding women in science, programs to specifically encourage female participation are essential.

Please join in combating this discouraging act against women in the STEM field by reminding NASA what WISH was really about.

I have several friends who have participated in this program, and it was an amazing experience for all of them. One is currently majoring in Engineering, and the other is majoring in Biology and Flute Performance. If I had known about this program when I was eligible, I would have loved to participate. It would have helped me immensely. 

You’ve probably seen me posting about how isolated I feel in my male-dominated physics and math classes. If you care about changing that to help the future women interested in STEM fields, please sign this petition.

After 400 years, mathematicians find a new class of shapes
“ In the millennia since Plato’s time, only two other collections of equilateral convex polyhedra have been found: Archimedean solids (including the truncated icosahedron) and Kepler solids (including rhombic polyhedra). Nearly 400 years after the last class was described, mathematicians claim that they may have now identified a new, fourth class, which they call Goldberg polyhedra.”
