"Frankenstein" by Mary Shelley

Kindle edition here.

• "I felt my heart glow with an enthusiasm which elevates me to heaven, for nothing contributes so much to tranquilize the mind as a steady purpose - a point from on which the soul may fix its intellectual eye."
• "But I have one want which I have never yet been able to satisfy, and the absence of the object of which I now feel as a most severe evil. I have no friend . . .when I am glowing with enthusiasm of success, there will be none to participate my joy; if I am assailed by disappointment, no one will endeavour to sustain me in dejection. I shall commit my thoughts to paper, it is true; but that is a poor medium for the communication of feelings . . . I have no one near me, gentle yet courageous, possessed of a cultivated as well as of a capacious mind, whose tastes are like my own, to approve or amend my plans."
• "He is so gentle, yet so wise; his mind is so cultivated, and when he speaks, although his words are culled with the choicest art, yet they flow with rapidly and unparalleled eloquence."

"Sidelights on Relativity" by Albert Einstein

• "One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of all other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts."

• "Newton's theory is probably the greatest stride ever made in the effort towards the causal nexus of natural phenomena."

• "And yet this theory evoked a lively sense of discomfort among Newton's contemporaries, because it seemed to be in conflict with the principle springing from the rest of experience, that there can be reciprocal action only through contact, and not through immediate action at a distance."

"My Heart Remembers" by Kim Vogel Sawyer

• "bits and snatches from the past hours cluttered Maelle's  mind in a confusing mosaic"
• " cry the hurt  away"
• "Maelle awakened Christmas morning with a dream hovering on the fringes of her mind."
• "Traveling alone often brought waves of melancholy, but on this particular morning she felt far from dismal. Who could be gloomy on such a glorious day? Overhead, fluffy clouds floated  lazily in a brilliant blue sky. The early spring rain had ignited  an abundance of fresh scents as well as brought a touch of green  to the landscape. If she squinted she could make out tiny buds  on the tips of bare trees. It wouldn't be long before wild flowers  would be making an appearance."
• "How many photographs had she  taken of children hiding their sad, hopeless situation behind  a forced smile?"
