GoKawiilBlog post explores why Coulomb's law is hard to verify with household experiments
A personal essay recounts the author's attempt to build intuitive, hands-on understanding of physics laws like Coulomb's law rather than relying on rote memorization or lookups. The writer describes citing advice from physicist Ramamurti Shankar to test physical laws with real instrumentation, and notes the practical difficulty of creating and measuring point charges at home, such as with a charged pen and hair.
