The one carries oxygen around, the other keeps the system clean. They’re teeny tiny.

## SONG: Levitating Diamonds (Tiny Impossible Things)

ARTIST: grant.

SOURCE:Based on “Lasers used to levitate glowing nanodiamonds in a vacuum”, Science Daily, 7 Sep 2015, as used in the post “A laser levitating glowing nanodiamonds in a vacuum..”

ABSTRACT: I really wanted to use “A laser levitating nanodiamonds in a vacuum” as a lyric, because it’s got such a great rhythm, but no, it didn’t happen.

Musically, things fell together well – I came up with chords on a guitar, and t…

## SONG: One (is the Loneliest Number) (penitential cover)

ARTIST: grant, featuring Sebastian Balfour. (Originally by Harry Nilsson.)

SOURCE: It doesn’t have a research source. It’s a penitential cover of a haunting song by Harry Nilsson that Three Dog Night turned into a prog anthem, which Aimee Mann turned into stunning reclamation project. Nilsson still wins.

ABSTRACT: I’ve been a penitential cover* behind for months and months. I first had the idea of doing this song in something like this way …

## Science Art: To Scale: The Solar System by Wylie Overstreet.

I like the desert in Nevada already because of the sense of perspective – such wide, flat spaces (wider and flatter even than Florida’s water-level wet prairies), sometimes flanked by mountains just big enough to provide a frame of reference. This is how small you are. This is how far you have to go.

That’s the ideal landscape for this kind of project. How big are we really? How far away is the place next door?

This far away. …

## Science Art: Aequorea Forbesiana by Philip Henry Gosse.

This is a jellyfish drawn by Philip Henry Gosse, a naturalist and Creationist (!) who gave us the word “aquarium” as a place to see marine creatures. Before Gosse, an aquarium was a place to water cattle.

He built the very first public one as the “Fish House” of the London Zoo in 1853.

A few years later, he published a book trying to prove that fossils couldn’t disprove Genesis because of course the act of creation would make things appear to be older than they are. …

## Science Art: A tightly wrapped trefoil knot, identified as the second member of the glueball spectrum, 2003.

From John P. Ralston’s “The Bohr Atom of Glueballs,” an article describing how to model an atom using rope and glue. Sort of.

Ralston does say it’s something anyone can do at home:

Measure the {\it lengths} of closed knots tied from ordinary rope. The “double do-nut”, and the beautiful trefoil knot are examples. Tie the knots tightly, and glue or splice the tails into a seamless unity. Compare two knots with corresponding members of the mysterious particle states known…

### New materials are really cool. Like, make-your-own-unplugged-AC cool.

5 December 2014 // 0 Comments

The Economist is following Stanford researchers who are (literally) making some really cool stuff: Fully 15% of the electricity used by buildings in the United States is devoted to [air conditioning]. If an idea dreamed up by Aaswath Raman of Stanford University and his colleagues comes to fruition, that may change. Dr Raman has invented a way to encourage buildings to dump their heat without the need for pumps and compressors. Instead, they simply radiate it into outer space. … To encourage one part of Earth’s surface (such as an individual building) to cool down, all you need do in principle is reflect the sunlight which falls on it back into space, while also encouraging as much radiative cooling from it as possible. To try to turn principle into practice Dr Raman has made a material which reflects 97% of sunlight while itself radiating at a wavelength of between eight and 13 microns (or millionths […]

### Bullet-proof fabric and cheap hydrogen fuel… and it comes from carbon.

3 December 2014 // 0 Comments

Nature celebrates more wonders – potential ones, from flexible armor to affordable fuel cells – that we can make from graphene: Protons’ ability to travel through graphene suggests that the material could be used as a membrane to sieve hydrogen from air, and to help extract energy from that hydrogen in a fuel cell, says co-author Andre Geim, a materials scientist at the University of Manchester, UK, who won a Nobel prize in 2010 for his pioneering experiments on graphene. Fuel cells convert the chemical energy stored in hydrogen (or other fuels) into electricity by breaking it apart into protons and electrons: the electrons race around an outside wire to create a current, with the protons flowing through a membrane within the cell. (Electrons and protons recombine at an electrode to react with oxygen.) Today’s membranes, such as a commercial polymer called Nafion, are tens of micrometres thick but do not entirely prevent hydrogen fuel […]

### Elon Musk designs X-Wing rockets & spaceport drones.

25 November 2014 // 0 Comments

Popular Mechanics gets all excited over PayPal/Tesla Motors/SpaceX magnate Elon Musk’s next set of high-tech tricks, including drones and rockets with unfolding wings (in a Star Wars-like configuration). if I had a billion dollars, I’d be doing this stuff too: The SpaceX chief unveiled the new Falcon 9R rocket design, which includes four guiding wings that unfurl shortly after launch. While subtitling it the “X-Wing” design, it’s actually the Hypersonic Grid Fins. Their X-configuration is meant to aid in the landing of the craft, one of the first ever reusable rockets. … But not to be outdone by introducing us to just a little piece of science fiction come to life, Musk also unveiled the Autonomous Spaceport Drone Ship, which uses oil rig technology to stay within a relative space of just under 10 feet, even in the harshest ocean conditions.
