• The popular physicists in a time span of an year, a decade or of all times (topic of debate now, is it?)
• The popular topics in physics (as in, famous / discussed / most sought after)
• On-click functionality enabling users to find the sub-fields which those physicists were most involved with, and also showing their collaborations (if any), with other physicists.
• The discovery patterns of atomic/sub-atomic particles in chronological order. For spreading awareness of how the knowledge of physicists, increased over time.
