* Dimension may not exsit - 2023 - A discussion about the modern city that is sometimes clear and sometimes vague. Measurement is a common way to learn from nature. In classical physics, physical properties are generally believed to have definite values, but errors are ubiquitous. We therefore try to measure and observe the city using plants as changing rulers that coexist with us. Focusing is an interesting process; while capturing data, we enter these cities. The proposal evokes not only an urban concept related to roots and tube-well systems, but also a discussion about the modern city in its shifting states of clarity and ambiguity.
