    "abstract": "Two damped coupled oscillators have been used to demonstrate the occurrence\nof exceptional points in a purely classical system. The implementation was\nachieved with electronic circuits in the kHz-range. The experimental results\nperfectly match the mathematical predictions at the exceptional point. A\ndiscussion about the universal occurrence of exceptional points -- connecting\ndissipation with spatial orientation -- concludes the paper.",
