Since hydrogen is a constituent of most of our electrolytic solvents, the definition of an acid or base as a substance which gives up or takes up hydrogen ion would be more general than the one we used before, but it would not be universal.

Since hydrogen is a constituent of most of our electrolytic solvents, the definition of an acid or base as a substance which gives up or takes up hydrogen ion would be more general than the one we used before, but it would not be universal.

We frequently define an acid or a base as a substance whose aqueous solution gives, respectively, a higher concentration of hydrogen ion or of hydroxide ion than that furnished by pure water. This is a very one sided definition.

We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms.

In the snobbery of science, each branch attempts to rise in the social scale by imitating the methods of the next higher science and by ignoring the methods and phenomena of the sciences beneath.

It must be admitted that science has its castes. The man whose chief apparatus is the differential equation looks down upon one who uses a galvanometer, and he in turn upon those who putter about with sticky and smelly things in test tubes.

Sometimes I think that our laboratories are but little earthworks which men build about themselves, and whose puny tops too often conceal from view the Olympian heights; that we who work in these laboratories are but skilled artisans compared with the man who is able to observe and to draw accurate deductions from the world about him.

To inquire into the origin of life is like seeking the origin of electrical machinery or the origin of music. Every increase in complexity of arrangement, of form, of substance, leads to new and often incalculable properties.

I have three brothers, and they'd torture me if I ever told them I liked a boy.

You can be powerful without being loud and aggressive.

Our enemy is by tradition our savior, in preventing us from superficiality.

A superb tenor voice, like a silver trumpet muffled in silk.

I will try to account for the degree of my aesthetic emotion. That, I conceive, is the function of the critic.

Spring and summer in Pittsburgh mean outdoor festivals.

It's always been my feeling that God lends you your children until they're about eighteen years old. If you haven't made your points with them by then, it's too late.

I run a fast pace on my sets, man. I like the energy of the scene to be the energy on the set. I think it affects the actors, and I think it affects the crew. There's that sensation like you're really shooting it for real, like in a documentary.

Grit is passion and perseverance for very long term goals. Grit is having stamina. Grit is sticking with your future day in day out. Not just for the week not just for the month but for years. And working really hard to make that future a reality. Grit is living life like its a marathon not a sprint.

Your soul may belong to Jesus, but your ass belongs to the marines.

One of the internet's strengths is its ability to help consumers find the right needle in a digital haystack of data.

Fashion has always been in conflict with convention. Style involves some knowledge of both. But you can pretty much forget these seasonal injunctions.

Picture-taking is an ensemble art - like theater.

I love dressing up. But I'm very low-maintenance; the week before an event, I'll choose something as quickly as possible and that's that. If I can do my own hair and make-up, even better. I like it to be fun.

And if we are in this state, if we had an eternity of probation, what reason have we to suppose that we should profit by it - if we had ever so long a time to chose for ourselves we should pursue our own will, to gratify our carnal I desires.

I decided to build a studio in my house. We built it in my basement kitchen. I had the drummer up by the fish tank. I was in the toilet singing. The bass player was out by the shelves in the living room, and the guitarist was on the couch by the telly.

Line is so versatile – you can do a fine, tight, closely observed description or simply put a line around an idea – like a cartoonist.

I know that if my mom fell and screamed for help my dad would jump right up to rescue her as soon as it was halftime.

I would write poems and think up melodies to them later.

You develop millionaires the way you mine gold. You expect to move tons of dirt to find an ounce of gold, but you don't go into the mine looking for the dirt-you go in looking for the gold.

Just as light brightens darkness discovering inner fulfillment can eliminate any disorder or discomfort. This is truly the key to creating balance and harmony in everything you do.

I grew up with both my parents around me at all times, but my kids are not knowing who I am half the time.

My favorite part of my appearance is my height. I'm five foot one and I feel feminine being small.

I'm a huge fan of Richard Curtis - there's real grief, real compassion in his films as well as cheekiness; it's a wonderful cocktail.
