Point discharge is an electrical process which occurs naturally in Earth's atmosphere. Like lightning, it has been observed both directly and indirectly for centuries. Several of the milestone investigations in atmospheric electricity have arisen through measuring point discharge. This work gives a history of various investigations involving the phenomenon and explains its central role in developments in atmospheric electricity.

This study reveals that a vast ancient lake once covered parts of central Iran, influencing regional culture and settlement. By analyzing old texts, maps, and environmental data, the research reconstructs the lake's size, timeline, and role in history. The findings suggest the lake lasted thousands of years before drying up due to climate shifts, offering new insights into how landscapes shaped early civilizations.

This paper reports a few anecdotes from the life of Paul J. Crutzen that were contributed by friends and colleagues. Taken together, these anecdotes should shed some light on the person that Paul was, as this is perhaps sometimes obscured when focusing solely on his many scientific achievements.

The meteorite "Veramin" fell in Persia ca. 1880. In the records, there are ambiguities about the event and the available sources were scrutinized in this review. The current official name, coined by meteoricist A. Brezina, is not supported by Iranian sources. A key document is a rediscovered label with the main mass of the meteorite. The indicated place of the event, probably occurring in February–April 1880, is Booghin of in the historical Zarand district, 100 km NW from Veramin (Varamin).
