A black and white photograph of a playful handwritten equation on unlined paper, capturing the whimsical substitution of "milk" for mass and "coffee" for the speed of light in E=MC². The bold, uneven pen strokes create a doodle-like sketch with personality and humor, rendered in medium focal length at eye level with a slight slant for a natural feel. The even overhead lighting eliminates shadows, highlighting consistent ink strokes against a textured, slightly rough paper background. The entire image is monochromatic, emphasizing the casual, spontaneous charm of a scientific joke brought to life through simple handwriting.
