Professor is a 46-bit still life consisting of two large islands (resembling a long4 clips) partially stabilizing each other and further stabilized by two blocks acting as induction coils.
The cis-mirrored variant of this still life occurred naturally from an asymmetric soup on July 9, 2016, in a haul submitted to Catagolue by Adam P. Goucher. It was formerly the largest still life to appear naturally, until its title was taken in August by the 56-cell cloverleaf interchange. Additionally, an inflected version of professor which also has 46 cells appeared naturally in February 2019.
A 8-glider synthesis of the professor was found in June 2023, improving over a 9-glider synthesis found several years earlier.
A number of variants are possible, depending on the alignment of the two halves and the position of the blocks:
