Otto and Otto (Otl)

Otto (Otl) Aicher designed the 1972 Munich Olympics. His pictograms replicated the world over, are a bit further down the line from the other Otto (Neurath).




Whereas this Otto and his isotypes dealt purely with graphical display of information, the quantitative and comparitive sort, Otl's holistic approach lent itself to things like picture books. I especially like his one on Isny, mentioned in metropolis magazine.


(David McFarline)

"in order to wake up the eye to this environment we need to give the eye a different picture of the surroundings."

PS. There's an exhibition of Aicher's work on at vitsoe from February 15th to coincide with the monograph coming out soon.

PPS. Neurath's introduction to the book laying out the international picture language/isotypes, the question of an international language is worth reading.

inside-out house, 1974

"We built a little house during the summer of 1974 just like the one Solon Gudmundsson had intended to build in 1938: an inside-out house whose interior was its exterior. Located in an uninhabited part of Iceland, out in a place where no other object made by man can be seen. The existence of this house is that "that which is outside" has shrunk, and reduced to dimensions of a closed space formed by the walls and roof of the house. Everything else has become "that which is inside." This house shelters the whole world, except itself."

"the platypus of physics"

subheading: imaginary solids
published title: impossible crystals
actual topic: quasicrystals
factual title: on tiles
Epilogue: to be continued

Introducing Hans Christian von Baeyer:


I've just read one of his stories in an Olaf Eliasson book called Surroundings Surrounded. Featuring:
Martin Gardner > Roger Penrose > M.C. Escher > Paul Steinhardt & Dov Levine > Robert Ammann > Fibonacci > David Nelson > Linus Pauling > George Onoda > Steinhardt again > the future.

It is so good I have applied a highlighter:

In 1977, Gardner asked his Scientific American readership how to cover a plane with tiles, with emphasis on the pentagon. I prefer to call it the fantom pentagon myself.

Fantom pentagon in aperiodic Penrose tiles:

(fat diamond=interior angles of reg. pentagon, skinny diamond=interior angles of pentagon's diagonals)

Penrose first arranged these tiles a short time after 1974. This is where I should stop and point at this story which tells it properly. Maybe I will. But that's a bit lazy. Ok I'll carry on being lay-ms: for a few years after, people played with 3D aperiodic tiling, making polyhedra to fill imaginary space.

And then came the thought: atoms instead of tiles.
In 1984 Paul & Dov made a computer program to calculate the diffraction patterns these imaginary structures would produce, if they were atoms. It would look like this:

Fantom pentagon x-ray. Ni glass, ni crystal:


Which brings me to the classification of dots, to be applied to every pure solid in nature:

Fuzzy = glass, sharp = crystal.
Random= glass, periodic = crystal.

This is where Ammann, amateur mathematician superstar, comes in and explains how dots can be both sharp and periodic: quasiperiodicity! (it involves fivefold grids made using fibonacci-adjusted spaces between parallel lines. These Ammann lines are 2 lengths, the ratio between them being golden.)

We have now covered the sub-heading and published title.

Which brings us to the discovery of such a thing actually existing, in 1984 - an alloy of aluminium and manganese. Which cannot be theoretically explained. Or found on flickr.

Which leaves us with the epilogue.
In 1988 Onoda managed to grow perfect quasicrystals in tiles with a set of local rules. Hans finished his story here as the ideas don't stretch outwards, restricted as they are by the ever-dramatic forbidden symmetry, coined by Marjorie Senechal.

Introducing Marjorie Senechal:


Marjorie wrote What is a Quasicrystal and was a member of the International Union for Crystallography's Aperiodic Crystal Commission in 1992, when they added a PS to the definition of a crystal, whereby if “three dimensional lattice periodicity can be considered to be absent,” the crystal is aperiodic (quasiperiodic).

She highlights the current gap between the study of mathematical long-range aperiodicity, and scientific research into aperiodic crystals: the former gives us rotational symmetry of any finite order, and the latter: pentagonal, decagonal, dodecagonal and icosahedral only. And insists that the term quasiperiodic (aperiodic) is not a cop-out. And finishes her paper with the words Stay tuned. Which is a cop-out.

Now I want to go to the APS meeting in March: Session D27: Fullerenes, Nano-membranes, and Quasicrystals.
