The discussion centers on the choice of paper for writing in math, physics, and engineering, questioning why notable scientists like Einstein used blank paper despite the availability of lined and grid options. Participants express varied preferences, with some favoring ruled paper for organization, while others prefer blank paper for creative freedom. The conversation highlights that personal comfort and departmental requirements often dictate paper choice. Some argue that using blank paper can enhance handwriting skills, while others find it challenging to maintain neatness without lines. The historical context of hand-drawing skills in engineering is also mentioned, emphasizing that earlier practices encouraged proficiency without reliance on ruled paper. Additionally, the use of engineering computation pads, which have grid lines on the back, is discussed as a practical solution for maintaining straight writing while allowing for sketches. Overall, the thread reflects a blend of nostalgia for traditional practices and the practicalities of modern engineering documentation.
