"A bird is an instrument working according..." - Quote by Leonardo Da Vinci

“Those who become enamoured of the art, without having previously applied to the diligent study of the scientific part of it, may be compared to mariners who put to the sea in a ship without rudder or compass and therefore cannot be certain of arriving at the wished for port.”

“Just as iron rusts from disuse, and stagnant water putrefies, or when cold turns to ice, so our intellect wastes unless it is kept in use.”

“A wave is never found alone, but is mingled with as many other waves as there are uneven places in the object where the said wave is produced.”

“For once you have tasted flight you will walk the earth with your eyes turned skywards, for there you have been and there you will long to return.”

“The human bird shall take his first flight, filling the world with amazement, all writings with his fame, and bringing eternal glory to the nest whence he sprang.”

“Into the air, over the valleys, under the stars, above a river, a pond, a road, flew Cecy. Invisible as new spring winds, fresh as the breath of clover rising from twilight fields, she flew.”

“Great engineers are a huge multiplier.”

“Software is a great combination between artistry and engineering.”

“Problems in human engineering will receive during the coming years the same genius and attention which the nineteenth century gave to the more material forms of engineering.We have laid good foundations for industrial prosperity, now we want to assure the happiness and growth of the workers through vocational education, vocational guidance, and wisely managed employment departments. A great field for industrial experimentation and statemanship is opening up.”
