The largest telescopes at present in existence are _reflectors_. It is much easier to construct a very large mirror than to construct a very large lens; it is also cheaper. A mirror is more likely to get out of order than is a lens, however, and any irregularity in the shape of a mirror produces a greater distorting effect than in a lens. A refractor is also more convenient to handle than is a reflector. For these reasons great refractors are still made, but the largest of them, the great Yerkes' refractor, is much smaller than the greatest reflector, the one on Mount Wilson, California. The lens of the Yerkes' refractor measures three feet four inches in diameter, whereas the Mount Wilson reflector has a diameter of no less than eight feet four inches. |
If I do not take these works so seriously as the reader may expect, let me beg him, before he blames me, to go to Oropa and see the originals for himself. Have the good people of Oropa themselves taken them very seriously? Are we in an atmosphere where we need be at much pains to speak with bated breath? We, as is well known, love to take even our pleasures sadly; the Italians take even their sadness allegramente, and combine devotion with amusement in a manner that we shall do well to study if not imitate. For this best agrees with what we gather to have been the custom of Christ himself, who, indeed, never speaks of austerity but to condemn it. If Christianity is to be a living faith, it must penetrate a man's whole life, so that he can no more rid himself of it than he can of his flesh and bones or of his breathing. The Christianity that can be taken up and laid down as if it were a watch or a book is Christianity in name only. The true Christian can no more part from Christ in mirth than in sorrow. And, after all, what is the essence of Christianity? What is the kernel of the nut? Surely common sense and cheerfulness, with unflinching opposition to the charlatanisms and Pharisaisms of a man's own times. The essence of Christianity lies neither in dogma, nor yet in abnormally holy life, but in faith in an unseen world, in doing one's duty, in speaking the truth, in finding the true life rather in others than in oneself, and in the certain hope that he who loses his life on these behalfs finds more than he has lost. What can Agnosticism do against such Christianity as this? I should be shocked if anything I had ever written or shall ever write should seem to make light of these things. I should be shocked also if I did not know how to be amused with things that amiable people obviously intended to be amusing. |
