Chemical Change Quotes

Although the problem of transmuting chemical elements into each other is much older than a satisfactory definition of the very concept of chemical element, it is well known that the first and most important step towards its solution was made only nineteen years ago by the late Lord Rutherford, who started the method of the nuclear bombardments.

In my early 30s, for a few months, I altered my body chemistry and hormones so that I was closer to a man in his early 20s. I was blown away by how dramatically my thoughts changed.

Catalysts are the conductors who choreograph the chemical dance that results in the formation of new structures.

And the first till last alshemist wrote over every square inch of the only foolscap available, his own body, till by its corrosive sublimation one continuous present tense integument slowly unfolded all marryvoising moodmoulded cyclewheeling history.

The well-known fact that the form of a specific substance, e.g. water, and hence its properties can alter without a change in composition was disposed of by the formal view that a physical, not a chemical, process was involved.

The distinction between the old and the new formulations consisting in the incorporation of the concept of the rate of chemical reactions is so great that it immediately asserted itself in the objective development of catalysis.

Physical changes take place continuously, while chemical changes take place discontinuously. Physics deals chiefly with continuous varying quantities, while chemistry deals chiefly with whole numbers.

I can only speak from my own experience, and I would say that the depression I experienced feels like a chemical change. When it came over me, when it comes over me, it feels like it's coming over me like a flu.

No new creation or destruction of matter is within the reach of chemical agency. We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen.

Thinking happy thoughts literally creates a positive chemical change in the brain which stimulates both positive physical and psychological benefits.

Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of weights of the sulfur burned and the oxygen absorbed.

September is different from all other months. It is more magical. I feel the strange chemical change in the earth which produces mushrooms is the cause, too, of the extra 'life' in the air - a resilience, a sparkle.

I hold the view that the alchemist’s hope of conjuring out of matter the philosophical gold, or the panacea, or the wonderful stone, was only in part an illusion, an effect of projection; for the rest it corresponded to certain psychic facts that are of great importance in the psychology of the unconscious. As is shown by the texts and their symbolism, the alchemist projected what I have called the process of individuation into the phenomena of chemical change.

The first unquestionable proofs of the transformation of elements into different chemical elements have been provided by the study of the phenomena of radioactivity.

Cellular pathology is not an end if one cannot see any alteration in the cell. Chemistry brings the clarification of living processes nearer than does anatomy. Each anatomical change must have been preceded by a chemical one.

You have to look at how chemistry develops.

When oxygen and sulphur dioxide are mixed in the presence of a filiament of platinum, they form sulphurous acid. This combination takes place only if the platinum is present; nevertheless the newly formed acid contains no trace of platinum, and the platinum itself is apparently unaffected: has remained inert, neutral, and unchanged. The mind of the poet is the shred of platinum.

Wine and the sun will make vinegar without any shouting to help them.

We see chemistry, how the atoms are arranged in the molecules, how the disease changes the arrangement. Perhaps we will find which drug disentangles the aggregates that make a brain senile. Many of us are interested in such things.

I probably have some sort of chocolate five times a week. There's definitely a change it does to the chemistry of the body. It's my favorite feeling. I live for it.

To the field of synthetic chemistry belongs an array of responsibilities which are crucial for the future of mankind, not only with regard to the health and needs of our society, but also for the attainment of a deep understanding of matter, chemical change, and life.

I consider myself an alchemist. An alchemist is basically a mystical chemist, right? And one of the great feats that alchemists used to do is they would take lead - just take a chunk of lead - and they could turn lead into gold.

With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms.

We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.

We are not only warming the ocean and the planet as a whole, but we are also acidifying the ocean and changing its chemistry.
