A Quote by Gilbert Newton Lewis

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.

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.

Gilbert Newton Lewis

The affinity of blood or pure haemoglobins for oxygen is a complex phenomenon, depending upon a number of conditions, the most important of which are temperature and hydrogen ion concentration.

August Krogh

In every combustion there is disengagement of the matter of fire or of light. A body can burn only in pure air [oxygen]. There is no destruction or decomposition of pure air and the increase in weight of the body burnt is exactly equal to the weight of air destroyed or decomposed. The body burnt changes into an acid by addition of the substance that increases its weight. Pure air is a compound of the matter of fire or of light with a base. In combustion the burning body removes the base, which it attracts more strongly than does the matter of heat, which appears as flame, heat and light.

Antoine Lavoisier

A marine protozoan is an aqueous salty system in an aqueous salty medium, but a man is an aqueous salty system in a medium in which there is but little water and most of that poor in salts.

The strands of the DNA double helix are held together by hydrogen bonding interactions between the complementary base pairs. Heating DNA in solution easily breaks these hydrogen bonds, allowing the two strands to separate - a process called denaturation or melting.

What a man can be, he must be. This need we call self-actualizat ion.

Abraham Maslow

Molecule, n.: The ultimate, indivisible unit of matter. It is distinguished from the corpuscle, also the ultimate, indivisible unit of matter, by a closer resemblance to the atom, also the ultimate, indivisible unit of matter ... The ion differs from the molecule, the corpuscle and the atom in that it is an ion.

Ambrose Bierce

I'm extremely happy the lithium-ion batteries helped communications around the world.

The emergence of Casual Fridays has created a fine line of fashion ion dos and donts.

The fluoride ion exerts its toxic effect by inhibiting the action of many enzyme systems.

Silence is one of the deepest Disciplines of the Spirit, simply because it puts the stopper on all self-justificat ion

As far as plants are concerned, they can't tell whether that nitrate ion comes from artificial chemicals or from decomposed organic matter.

Here's the thing: I left Ion Storm and Eidos in the spring of 2004 frankly because I felt out of place at that company.

There is one experiment which I always like to try, because it proves something whichever way it goes. A solution of iodine in water is shaken with bone-black, filtered and tested with starch paste. If the colorless solution does not turn the starch blue, the experiment shows how completely charcoal extracts iodine from aqueous solution. If the starch turns blue, the experiment shows that the solution, though apparently colorless, still contains iodine which can be detected by means of a sensitive starch test.

The Brits always favor the underdog. There's an eccentricity to us, and I think you can see that through the fash- ion and the music and the way people look.
