Flight By Machines Heavier Than

Aerial Flight Is One Of That Class Of Problems With Which Man Will Never Be Able To Cope. . . . The Example Of The Bird Does Not Prove That Man Can Fly. Imagine The Proud Possessor Of The Aeroplane Darting Through The Air At A Speed Of Several Hundred Feet Per Second. It Is The Speed Alone That Sustains Him. How Is He Ever Going To Stop?

I Finally Reached The Conclusion That Mathematics Was The Study I Was Best Fitted To Follow, Though I Did Not Clearly See In What Way I Should Turn The Subject To Account.

The Mathematician Of To-day Admits That He Can Neither Square The Circle, Duplicate The Cube Or Trisect The Angle. May Not Our Mechanicians, In Like Manner, Be Ultimately Forced To Admit That Aerial Flight Is One Of That Great Class Of Problems With Which Men Can Never Cope... I Do Not Claim That This Is A Necessary Conclusion From Any Past Experience. But I Do Think That Success Must Await Progress Of A Different Kind From That Of Invention.

What We Now Call School Training, The Pursuit Of Fixed Studies At Stated Hours Under The Constant Guidance Of A Teacher, I Could Scarcely Be Said To Have Enjoyed.

We Are Probably Nearing The Limit Of All We Can Know About Astronomy.
