The eternal battle between engineers and chemists captured in one beautiful moment. On the left, the practical engineer sees a simple diode symbol - a functional electronic component that lets current flow in one direction. On the right, the pretentious chemist sees the same lines as 1,1-dimethyl cyclopropane - a carbon ring structure with two methyl groups. Same drawing, completely different worlds. This is why interdisciplinary meetings take five hours and accomplish nothing.
