Something on the smoothness of Titan’s hydrocarbon lakes

If you are interested, go here:

A discussion session on a suggestion of mine on how “azotosomes” might increase the viscosity and therefore flatness of the hydrocarbon lakes on Saturn’s moon Titan.

The New Zealand kea: another “rainbow bird”

 

The kea is an odd, rather obscure New Zealand parrot. I only just discovered that its plumage has the colours in the same order as those in the rainbow. I have written about how common this is in parrots before.

Also common is the orange/yellow juxtaposition seen on the underside of the bird.

Womanspreading

Traditionally and sensibly, women used to keep their vulva and vagina covered and hidden. There IS a mystery about that part of a woman’s body. But it is also vulnerable. Dressing modestly and keeping their legs together has therefore been traditionally seen as decent, feminine behaviour.

Feminists have attempted to reverse this natural inclination by claiming some illusory “power” for their genitals and breasts, and showing them off at every opportunity (pussy hats, Femen). But it makes no sense to lead with one’s most vulnerable point.

Womanspreading is not empowering. Undressing is not empowering. A freed nipple is not empowering. At best it looks absurd. At worst it just draws the “male gaze” even more powerfully.

Women’s wide hips

According to the article cited below, women’s wide hips do not mean inefficient locomotion. The author also seems to be arguing that childbirth does not require wide hips. So, why wide hips? I am wondering if it is something to do with the strength and/or stability of triangles (such as that made by a wide pelvis and the legs) and the way women need to carry babies and young children efficiently, with the downward force towards the ground.

Stability might be particularly important when carrying a baby or child because of the risk of injury to the young.

This includes several interesting essays including some thoughts on benign patriarchy. I believe we currently have a benign patriarchy in the West, which should be conserved.
