Plate 9:  Individuals with normal vision or tritanopia will see the number 56. Individuals with protanopia, deuteranopia, or achromotopsia will see no numbers.

Plate 19: Individuals with normal vision or tritanopia will see the number 5. Individuals with protanopia or deuteranopia will see the number 2. Individuals with achromotopsia will see no numbers.

Plate 34. Individuals with normal vision, tritanopia, or achromotopsia will see no numbers. Individuals with protanopia or deuteranopia will see the number 73.

Yay still colorblind

Who said that corals are just rocks??? This lively Mussidae colony was captured at night when its polyps —equipped with little stingers called nematocysts— were extended to feed.  Photo: David Gruber and Vincent Pieribone.

We often forget that WE ARE NATURE. Nature is not something separate from us. So when we say that we have lost our connection to nature, we’ve lost our connection to ourselves.

Sometimes everything is so beautiful and overwhelming that I can’t think at all

So my friend has this idea

  • Kyle: time for a rewrite
  • Kyle: make it about a supernova
  • Kyle: an impending supernova
  • Kyle: "The Fault in Our Star"

The Elements According to Relative Abundance

Roughly, the size of an element’s own niche is proportioned to its abundance on Earth’s surface, and in addition, certain chemical similarities. 

source

This chart was published in 1976 so it’s obviously outdated and some of the proportions are way off. For example, Astatine (At) looks rather large despite the fact that is one of the rarest elements on Earth, with a total existing amount of less than one gram at any given time. Francium (Fr) is also extremely rare - there is at most one ounce in the Earth’s crust at any time - and yet it looks larger than Neodymium (Nd) which, although it belongs to the rare-earth metals, is not rare at all. Its abundance in the Earth’s crust is about 38 mg/kg, which is the second highest among rare-earth elements, following cerium.

But the idea is really cool!

This is probably the coolest GIF I’ve ever seen.

now there’s some perspective.

I once saw a storm roll like this once. It was beautiful.

It was sunny as my friend and I were walking to another friends house and I hear this roar, look over and it’s a hail storm coming right at us and within seconds we were running in it to get away.

 monika horcicova 3D prints the wheel of life skeletal sculpture

made from 3D printed pieces, ‘the wheel of life’ by czechdesigner monika horcicova is a skeletal sculpture that is based on a symbol of infinity. the round structure refers to the repeated cycle of conception and death, with walking legs used to evoke the image of people in motion. the idea explores the fragility of human bones, which despite this are able to carry the weight of the whole human figure during its life. the plaster composite pieces were 3D printed and then placed in a form and casted in a polyurethane resin, the individual pieces were then assembled into a single object.
