The middle of the eighteenth century reportedly witnessed the emergence of the new literary movement in Persian poetry, called the "bāzgasht-e adabi," or literary return, which rejected the seventeenth-century mainstream Indian or tāza-guʾi style. This literary movement recently merits increased attention from many scholars who are interested in wider Persianate cultures. This article explores the reception of this movement in late eighteenth- and early nineteenth-century Iran and the role played by the Qajar royal court in it, mainly by the analysis of a specific sub-genre of tazkeras, called "royal-commissioned tazkeras," which were produced from the reign of the second Qajar monarch Fath-ʿAli Shāh onward. A main focus will be on the reciprocal relationship between the court poets/literati and the shah, which presumably somehow affected our understanding of Persian literature today.

Gravity generated by large masses has been observed using a variety of probes from atomic interferometers to torsional balances. However, gravitational coupling between small masses has never been observed so far. Here, we demonstrate sensitive displacement sensing of the Brownian motion of an optically trapped 7 mg pendulum motion whose natural quality factor is increased to 108 through dissipation dilution. The sensitivity for an integration time of one second corresponds to the displacement generated in a millimeter-scale gravitational experiment between the probe and a 100 mg source mass, whose position is modulated at the pendulum mechanical resonant frequency. Development of such a sensitive displacement sensor using a milligram-scale device will pave the way for a new class of experiments where gravitational coupling between small masses in quantum regimes can be achieved.
