# Physicists Scott Diddams and Scott Papp

NIST physicists Scott Diddams (left) and Scott Papp with a prototype atomic clock based on a chip-scale frequency comb. Diddams is holding the silicon chip, which fits into the clock apparatus on the table. With performance improvements and further reductions in size, the technology might eventually be used to make portable tools for measuring time and frequency.
