"Back in 1936, renowned sculptor Isamu Noguchi was in Mexico working on a 72-ft-long public mural when he hit a snag: for some reason, he couldn't precisely recall the famous formula, E=mc². Rather than risk a mistake, he decided to seek advice and wired his good friend, Buckminster Fuller — a famed architect and great admirer of Einstein — for clarification. Rather than just respond with the equation, Fuller went the extra mile and soon sent the following to his friend — a magnificent telegram in which he also explained it in 264 words." - Amira
