British, French, Japanese and US teams added accelerators to electron microscopes. Now voltages ten times conventional levels permit viewing of thicker, more representative specimens.

Why are some violins better than others? Studies with modern electroacoustical techniques yield at least part of the answer and give us information that helps build good fiddles.

Recent developments in both hardware and software hold great promise for effective use of computer systems in nuclear‐physics laboratories. Interaction between physicists and computers is, consequently, being simplified.

These two complementary methods of 3D imaging both have their special advantages. Lensless photography, or holography, provides a method for precise distortion measurements, information storage and studies, such as bubble‐chamber photography, that require great depth of field. Lenslet, or integral, photography does not need coherent light and is therefore tolerant of subject motion.
