The x-ray of your skull shows a large, flobby mass floating inside. I have to consult my colleagues to be certain, but it looks like a long sausage snarled into a lump.

It's a shame, when I'm at the checkout line, and the cashier holds up my bill to the light, in search for a ghost president, or slashing a yellow marker to see if counterfeit. Even in money we can't be trusted. Makes we wonder whats next, will the government make a marker to slash our hand, or an x-ray we will have to walk through, to check if we have a dishonest heart or corrupt spirit?

I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper. ...The effect was one which could only be produced in ordinary parlance by the passage of light. No light could come from the tube because the shield which covered it was impervious to any light known even that of the electric arc. ...I did not think I investigated. ...I assumed that the effect must have come from the tube since its character indicated that it could come from nowhere else. ... It seemed at first a new kind of invisible light. It was clearly something new something unrecorded. ...There is much to do, and I am busy, very

People ask me where I got my x-ray powers. I inherited them from my parents in parental supervision. Erase the dots and your doubts if you think that I was 'raysed' alone.

Borges's extreme architecture attempts to visualize the universe by assigning to every object real and unreal, now and yet to come, a code or sign, a corresponding figure within the Library. It seeks to render totality visible, to effect a total visibility and visuality. The Library of Babel is a view of the universe inside and out, an X-ray of the universe and universal X-ray, seen from within and without. It is a representation of everywhere: a perfect duplication of the universe. And of you: universal. An endless and eternal cinema, an imaginary archive that extends into the universe until it is indistinguishable from it, until you are indistinguishable from the universe.

Or the woman in front of me in the security line who asked if they would put her cat, Dave, through the luggage X-ray machine because she wanted to see if he'd eaten a necklace.

In describing a protein it is now common to distinguish the primary, secondary and tertiary structures. The primary structure is simply the order, or sequence, of the amino-acid residues along the polypeptide chains. This was first determined by [Frederick] Sanger using chemical techniques for the protein insulin, and has since been elucidated for a number of peptides and, in part, for one or two other small proteins. The secondary structure is the type of folding, coiling or puckering adopted by the polypeptide chain: the a-helix structure and the pleated sheet are examples. Secondary structure has been assigned in broad outline to a number of librous proteins such as silk, keratin and collagen; but we are ignorant of the nature of the secondary structure of any globular protein. True, there is suggestive evidence, though as yet no proof, that a-helices occur in globular proteins, to an extent which is difficult to gauge quantitatively in any particular case. The tertiary structure is the way in which the folded or coiled polypeptide chains are disposed to form the protein molecule as a three-dimensional object, in space. The chemical and physical properties of a protein cannot be fully interpreted until all three levels of structure are understood, for these properties depend on the spatial relationships between the amino-acids, and these in turn depend on the tertiary and secondary structures as much as on the primary. Only X-ray diffraction methods seem capable, even in principle, of unravelling the tertiary and secondary structures.[Co-author with G. Bodo, H. M. Dintzis, R. G. Parrish, H. Wyckoff, and D. C.
