Back a few pages: Good pick, Off White. Diane Arbus was amazing. Lurid yet so engaging.
And the rest... Good stuff all around!

Beckett:
Waiting for Godot
Endgame
Simon McBurney discusses the terror of playing Clov in Complicite's production of Samuel Beckett's Endgame: [...] "Beckett is special, Endgame particularly so. It is unlike anything else I have played: fastidiously specific, utterly elusive. At any one moment in the performance, you will be aware of someone laughing hysterically, another weeping, while others sit silent, astounded or baffled. Endgame resists narrative and even thematic explanation. How you play it has to reflect this. If you decide something too much in advance, you forget the element that gives the play life – the audience."

A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). As with any transmission illumination scheme, the electrons pass through a sufficiently thin specimen. However, STEM is distinguished from conventional transmission electron microscopes (CTEM) by focusing the electron beam into a narrow spot which is scanned over the sample in a raster.
The rastering of the beam across the sample makes these microscopes suitable for analysis techniques such as mapping by energy dispersive X-ray (EDX) spectroscopy, electron energy loss spectroscopy (EELS) and annular dark-field imaging (ADF). These signals can be obtained simultaneously, allowing direct correlation of image and quantitative data.
By using a STEM and a high-angle detector, it is possible to form atomic resolution images where the contrast is directly related to the atomic number (z-contrast image). The directly interpretable z-contrast image makes STEM imaging with a high-angle detector appealing. This is in contrast to the conventional high resolution electron microscopy technique, which uses phase-contrast, and therefore produces results which need interpretation by simulation.
Usually STEM is a conventional transmission electron microscope equipped with additional scanning coils, detectors and needed circuitry; however dedicated STEMs are manufactured also.
