How Do They Do It?

The programme examines the intricate technological processes required to develop radar systems, detailing each step from design through implementation. It also explores the methods used in cultivating and producing pistachios, covering everything from planting and growth to harvesting and processing.

Pistachios/Forbidden City/Radar is an episode of a programme that brings together two seemingly unrelated subjects. In this instalment, the focus shifts between the intricate world of radar technology and the agricultural processes behind pistachio cultivation, offering viewers a look at both high‑tech engineering and traditional farming. The episode is structured to juxtapose these areas, highlighting the detailed work required in each field. The first part of the show examines the complex technological processes involved in creating radars. It walks the audience through the various stages of design, component assembly and testing that enable radar systems to detect and track objects. By breaking down each step, the episode illustrates how precision engineering and sophisticated electronics combine to produce functional radar equipment. The second segment turns to the production of pistachios, outlining the steps from orchard planting to harvest. It details the careful cultivation methods, irrigation practices and harvesting techniques that growers employ to bring the nuts to market. The programme highlights the labour‑intensive nature of pistachio farming and the attention to detail needed to maintain quality. Overall, the episode presents both topics side by side, showing how each relies on meticulous processes—whether in a high‑tech lab or a sun‑lit orchard. By linking radar development with pistachio production, the show underscores the diverse ways specialised knowledge and careful craftsmanship shape the world around us.
