␈↓ ↓H␈↓Dear Professor Chandy:

␈↓ ↓H␈↓        Sorry␈α⊂for␈α∂the␈α⊂long␈α∂delay␈α⊂in␈α⊂the␈α∂letter␈α⊂about␈α∂Boyer␈α⊂and␈α⊂Moore.␈α∂ I␈α⊂was␈α∂hoping␈α⊂to␈α⊂≡nd␈α∂a

␈↓ ↓H␈↓Moreover, they have applied their methods to a wider variety of problems than other workers.

␈↓ ↓H␈↓        Their␈α∞productivity␈α∞seems␈α

␈↓ ↓H␈↓        In short I think there is an ideal case for making them full professors.
