It took nearly 6,400 years to go from the simple wheel to the first automobile, but only two decades from the first car to roll off the assembly line to the first aircraft to take to the skies. Such rapid developments in quality of life can only be attributed to the human spirit, an unstoppable force always in pursuit of improvement. Join Modern Sciences in celebrating the spirit of human ingenuity through its engineering feats.
