It has been shown that, in the article by G. B. Malykin and V. I. Pozdnyakova “On the Velocity of a Light Spot Moving over a Cylindrical Screen” [Tech. Phys. 52, 133 (2007)], errors were made in the calculation of the velocity of a light spot moving over a cylindrical screen. As a result, incorrect formulas were obtained to calculate the velocity of the light spot as applied to classical mechanics and the Tangherlini transformation. Correct formulas for calculating the velocity of a light spot moving over a cylindrical in classical mechanics and in the Tangherlini transformation are proposed.
