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.

There are no uninteresting things only uninterested people.

The ideally non-violent state will be an ordered anarchy.

I want to spend as much time as possible with my children, so I always like to keep my beauty and fashion routines effortless... but still chic!

When you speak of role models, when we talk to our kids, everybody is a role model, everyone, just as you look at a Michael Jordan to be the terrific athlete he is.

Expositions are the timekeepers of progress.

We have more power than will; and it is often by way of excuse to ourselves that we fancy things are impossible.

I've campaigned for people. I've campaigned across the country for people. I have supported people in local elections. I do work with groups and causes. So, I feel like I am a participant and a civically-engaged citizen.

I've been very blessed to work in some films that I'm very proud of.

When you're talented, you're talented.

I don't consciously go out looking for themes. They attach themselves to me.

Sometimes when you tell a story, you reach a little bit too far just to make the story a better one.

I am disappointed that Senator Ayotte has voted repeatedly for deep cuts in Pell Grants that would make college more expensive for thousands of New Hampshire students and voted against allowing young people to refinance their student loans.

A person without a sense of humor is like a wagon without springs, jolted by every pebble in the road.

Once again, we come to the Holiday Season, a deeply religious time that each of us observes, in his own way, by going to the mall of his choice.

I've been informed by both sides, jazz, western music, Asian music, African music, all sides, because I've been interested in the sound of the universe, and that sound is without limit.

When I first became involved with PETA, it was on an 'issue-by-issue' basis - they interviewed me in my old apartment about animal abuse in the circus as I sat on a leather sofa.

To be with a hopeless romantic is an everyday valentines day but it also meant days of tears and pain that will push you to your limit.

At my age, turning gray is kind of a blessing, where it softens all of the other horrible things it does to you, but it is what it is.

I am ashamed to admit I watch a lot of reality shows like The Osbournes and The Bachelor.

Fire has impacted every part of our lives - without fire, there would be no shopping, right? - that's how the Internet will intrude on our lives, particularly our kids' lives.

I have the feeling it will influence my future writing to the extent that without any material worries I could develop a greater ease, even lightheartedness, in my writing.

Putting out a debut album is a bit scary - I want it to be just right, so I took some extra time to finish it. Eminem's increased involvement has been such a blessing; I'm getting guidance from an artist I really admire and trust.

The Dominican Republic says 'We're black behind the ears.' And in Mexico, 'there's a black grandma in the closet.' They know, they've just been intermarrying for a long time. But if we did the DNA of everyone in Mexico a whole lot of people would have a whole lot of black in them.

I love it when a character requires me to look less than my red-carpet best.
