I cannot endure to waste anything so precious as autumnal sunshine by staying in the house.
[Notebook, Oct. 10, 1842] — Nathaniel Hawthorne

The problem with common sense is, it isn't. — Benjamin Franklin

It is not by change of circumstances, but by fitting our spirits to the circumstances in which God has placed us, that we can be reconciled to life and duty. — Frederick William Robertson

Selection of crews is always been somewhat of a mystery. — Robert Crippen

Nobody before the Pythagorean had thought that mathematical relations held the secret of the universe. Twenty-five centuries later, Europe is still blessed and cursed with their heritage. To non-European civilizations, the idea that numbers are the key to both wisdom and power, seems never to have occurred. — Arthur Koestler

We used to have front-row seats for the Grand Opera House pantomime every year, and once the dame May McFettridge got me up on-stage. — Rachel Tucker

And that's the real reason the powerful fear open systems and networks. If anyone can set up a free voicecall to anyone else in the world, using the net, then we can all communicate with the same ease that's standard for the high and mighty. [ ... ]
And if any worker, anywhere, can communicate with any other worker, anywhere, for free, instantaneously, without the boss's permission, then, brother, look out, because the Coase cost of demanding better pay, better working conditions and a slice of the pie just got a *lot* cheaper. And the people who have the power aren't going to sit still and let a bunch of grunts take it away from them. — Cory Doctorow

The world as an arena contains different tomorrows. When you see a different today, you shall think of a different yesterday and there shall come yet another and a different tomorrow! Day by day, night by night, we meet another tomorrow with different perspectives. If the good tomorrow you thought of becomes a bad today, don't worry at all and pray, another tomorrow is coming for today to be yesterday! Don't ever let desperation take the seat of inspiration within you! Keep Smiling, no matter what; for though all things go wrong, something is right somewhere! Just ponder, smile, be happy, shake of the dust and arise for another tomorrow is coming! — Ernest Agyemang Yeboah

[The] structural theory is of extreme simplicity. It assumes that the molecule is held together by links between one atom and the next: that every kind of atom can form a definite small number of such links: that these can be single, double or triple: that the groups may take up any position possible by rotation round the line of a single but not round that of a double link: finally that with all the elements of the first short period [of the periodic table], and with many others as well, the angles between the valencies are approximately those formed by joining the centre of a regular tetrahedron to its angular points. No assumption whatever is made as to the mechanism of the linkage. Through the whole development of organic chemistry this theory has always proved capable of providing a different structure for every different compound that can be isolated. Among the hundreds of thousands of known substances, there are never more isomeric forms than the theory permits. — Nevil Vincent Sidgwick

I'm always left with such a barren idea of myself if I let an opportunity pass. I get home and I feel like yesterday's dirty plates, smeared in dried sauce and grease. I have this idea that it's the women we don't sleep with who haunt us. They become like a missing page in our book. The part of the story we'll never know. — Glenn Haybittle
