Expand and outpaint this horizontal image into a perfect 1:1 square aspect ratio. Maintain the central composition exactly as it is, ensuring that the entire text "4 ЗАКОНА ФИЗИКИ ДЛЯ УВЕРЕННОГО ВЫСТУПЛЕНИЯ" remains fully visible, centered, and completely untouched. Extend the background vertically (upwards and downwards) by seamlessly continuing the classroom setting, the dark interactive screen, the speaker on the right in a grey vest, and the blurred shoulder of the person in the foreground on the left. Keep the neon physics icons (magnet, atom, pendulum, prism) exactly in their places and fully intact. The style, colors, lighting, and overall high-quality photographic look must be perfectly preserved.
