Light blue Science And Technology Book Cover Design (Evoking modern, beautiful, and serene)

Visuals: The cover features a luminous, glowing apple with a futuristic, modern cityscape encapsulated inside it. The skyline prominently displays the Milad Tower, symbolizing Tehran, with a mix of modern architectural elements. The glowing apple sits firmly on a textured, vibrant Earth, emphasizing stability and sustainability. The background showcases a gradient of light blue shades, transitioning into a peaceful sky scattered with delicate, pink cherry blossom petals floating gracefully as if suspended in air. Soft beams of light radiate from behind the apple, creating depth and a sense of enlightenment.

Typography: Clean, sans-serif font such as "Avenir" is used for the title, placed at the top of the cover in white-like text for high contrast and readability. The subtitle is written with a slightly thinner variation of the same font beneath the title in lighter blue to harmonize with the background. The text alignment is centered, ensuring clarity and order.

Layout: The luminous apple is placed in the center, creating an immediate focal point. The title is positioned at the top in large, bold letters. Beneath it, the subtitle is slightly smaller and thinner. The cherry blossoms are scattered across the cover, some near the top edges, creating a dreamy halo effect. The Earth base with the glowing apple fills the lower third of the cover. Negative space is thoughtfully utilized to maintain a clean yet impactful aesthetic.

Explanation: The visual composition was designed to symbolize sustainability and innovation while paying homage to Tehran through the iconic Milad Tower. The glowing apple signifies prosperity and the harmonious coexistence of modern urban planning within nature. The Earth forms a strong foundation, emphasizing the stability of sustainable design. The floating cherry blossoms and gradient blue sky evoke hope, peace, and positivity, aligning with the tone of sustainable urban development.
