Walz of the Polypeptides by Mara G. Haseltine

Haseltine on her project:

The inspiration for Waltz of the Polypeptides (2003) comes from one of the smallest muses on the planet, a subject so tiny it can only be seen with an electron microscope. It is a sub-cellular organelle called a rhibosome. Within each cell, ribosomes produce the smallest functional elements in all living organisms, proteins. In Waltz of the Polypeptides the viewer literally walks through the birth of a single protein.

To create this work, Mara G. Haseltine studied the ribosomes and proteins and used accurate molecular renderings of electron microscopic and nuclear magnetic resonance images for her armatures. She manipulated this raw data using a 3-D computer program into a design which kept the integrity of Mother Nature’s form while simultaneously creating a work that was comprehensible and pleasing to its viewers. She then fabricated this design into three-dimensions using computer-driven 5-axis milling and rapid prototyping technologies. The work itself was created to be part of a living landscape inspired by the Zen gardens of Kyoto. Each part of the landscape represents a different part of the cell. Thus, when the viewer experiences Waltz of the Polypeptides, they are fully immersed into a fantastical environment based on a tiny part of the human body.

Yeah I'm sorry but what the heck was that about a Scorpion King?? Like where did that come from? And "Voldemort Day?" What kind of crack is this?? I'm glad I'm not the only one who feels the same. I loved the play's characters and most of the plot was good but some things just... ????

I don’t even know man… pretty sure everyone - authors and actors - were on drugs

one neat thing I’d never thought about before is that you can have macromolecules with a transition between a disordered and an ordered state—with the ordered state at the higher temperature! (this is surprising because one thinks of ordered states as having lower entropy than disordered ones, and higher temperatures tend to favor higher-entropy states. you could think of it as: high temperature means your system is getting more/stronger random kicks into random microstates [as described by detailed positions of atoms etc], which thus tends to send it into whichever macrostate [overall description, here “ordered” or “disordered”] matches more microstates [i.e. has higher entropy—and there are more ways of being disordered than of being ordered].)

one of the examples is a polypeptide that can be a random coil (disordered) at lower temperatures and an alpha helix (ordered) at higher temperatures. spoiler under the cut.
