Black and white illustration on pure jet black background, centered composition featuring hand-drawn chalk-style text at top reading "E=MC²" with subtitle "(ENERGY = MILK x COFFEE²)" in rough, textured white lettering with organic imperfect edges suggesting white chalk on blackboard, below which sits a minimalist line-drawn coffee mug rendered in simple white strokes with crosshatch shading detail on the body, filled with rich dark brown coffee liquid creating strong tonal contrast, clean handle with subtle dimension, monochromatic palette with no color, high contrast between pure white linework and absolute black void background, conceptual humorous graphic design blending physics education with caffeinated energy humor, flat illustrative style with sketch-like character, minimal detail emphasizing bold graphic simplicity and clarity of the joke composition, suitable for poster, merchandise, or educational satire artwork, crisp white lines against deep black creating striking visual impact with no gradients or shading beyond basic line weights and crosshatching, timeless graphic design aesthetic reminiscent of chalkboard art or vintage educational diagrams reimagined with contemporary coffee culture humor.
