Elementary Microscopy

This is a very useful hook and can be strongly recommended to all would-be purchasers of a microscope. It consists of chapters on the simple and compound microscope, on the stands, on objectives and eye-pieces, on various accessories, such as substage condensers, the Abbe illuminator, diaphragms, polarising apparatus, reflectors, light modifiers, &c., &c. We are glad to see the high opinion the...

Elementary steps at the surface of ice crystals visualized by advanced optical microscopy.

Due to the abundance of ice on earth, the phase transition of ice plays crucially important roles in various phenomena in nature. Hence, the molecular-level understanding of ice crystal surfaces holds the key to unlocking the secrets of a number of fields. In this study we demonstrate, by laser confocal microscopy combined with differential interference contrast microscopy, that elementary step...

Elementary arithmetic

There is a quite natural way in which the safe/normal variable discipline of Bellantoni-Cook recursion (1992) can be imposed on arithmetical theories like PA: quantify over safes and induct on normals. This weakens the theory severely, so that the provably recursive functions become more realistically computable (slow growing rather than fast growing). Earlier results of Leivant (1995) are re-w...
