Chemistry Reactions Quotes & Sayings

There are cognitive processes and limbic reactions associated with basic emotions. And you can change brain chemistry, but you're still not going to change memories and experiences in a human being. — Helen Fisher

Biochemistry is the science of life. All our life processes - walking, talking, moving, feeding - are essentially chemical reactions. So biochemistry is actually the chemistry of life, and it's supremely interesting. — Aaron Ciechanover

The ideal of the 11th/17th century physicists was to be able to explain all physical reality in terms of the movement of atoms. This idea was extended by people like Descartes who saw the human body itself as nothing but a machine. Chemists tried to study chemical reaction in this light and reduce chemistry to a form of physics, and biologists tried to reduce their science to simply chemical reactions and then finally to the movement of physical particles. The idea of reductionsm which is innate to modern science and which was only fortified by the tehory of evolution could be described as the reduction fo the spirit to the psyche, the psyche to biological activity, life to lifeless matter and lifeless matter to purely quantitative particles or bundles of energy whose movements can be measured and quantified. — Seyyed Hossein Nasr

Life may be chemistry, but it's a special circumstance of chemistry. Organisms exist not because of reactions that are possible, but because of reactions that are barely possible. Too much reactivity and we would spontaneously combust. Too little, and we would turn cold and die. Proteins enable these barely possible reactions, allowing — Siddhartha Mukherjee

these are the topics that MCAT 2015 will no longer test: General Chemistry Phase equilibria removed Exception: phase diagrams still tested Organic Chemistry Several compounds no longer directly tested Simple organic compounds (alkanes, alkenes, alkynes); Exception: nucleophilic substitution reactions still tested Aromatic compounds Ethers Amines Physics Momentum removed Solids (density, elastic properties, and so on) removed Periodic motion (springs & pendulums) removed Exception: Spring potential energy still tested — Kaplan Inc.

The chemists who uphold dualism are far from being agreed among themselves; nevertheless, all of them in maintaining their opinion, rely upon the phenomena of chemical reactions. For a long time the uncertainty of this method has been pointed out: it has been shown repeatedly, that the atoms put into movement during a reaction take at that time a new arrangement, and that it is impossible to deduce the old arrangement from the new one. It is as if, in the middle of a game of chess, after the disarrangement of all the pieces, one of the players should wish, from the inspection of the new place occupied by each piece, to determine that which it originally occupied. — Auguste Laurent

Scheele, it was said, never forgot anything if it had to do with chemistry. He never forgot the look, the feel, the smell of a substance, or the way it was transformed in chemical reactions, never forgot anything he read, or was told, about the phenomena of chemistry. He seemed indifferent, or inattentive, to most things else, being wholly dedicated to his single passion, chemistry. It was this pure and passionate absorption in phenomena-noticing everything, forgetting nothing-that constituted Scheele's special strength. — Oliver Sacks

Carbon-carbon bond formation reactions are important processes in chemistry because they provide key steps in building complex, bio-active molecules developed as medicines and agrochemicals. — Akira Suzuki

The problem with chemistry is that it tends to blow things up. And she is already a chain of reactions building up inside. — Lauren Beukes

Understanding the physiological and neurological features of spiritual experiences should not be interpreted as an attempt to discredit their reality or explain them away. Rather, it demonstrates their physical existence as a fundamental, shared part of human nature. Spiritual experiences cannot be considered irrational, since we have seen that, given their physiological basis, experiencers' descriptions of them are perfectly rational... All human perceptions of material reality can ultimately be documented as chemical reactions in our neurobiology; all our sensations, thoughts, and memories are ultimately reducible to chemistry, yet we feel no need to deny the existence of the material world; it is not less real because our perceptions of it are biologically based... It is not rational to assume that the spiritual reality of core experiences is any less real than the more scientifically documentable material reality. — Sabina Magliocco

He points out that mystics have always worked systematically to modify their brain chemistry, whether through fasting, self-flagellation, sleeplessness, hypnotic movement, or chanting.* The brain can be made to drug itself, as seems to happen with certain placebos. We don't merely imagine that the placebo antidepressant is working to lift our sadness or worry - the brain is actually producing extra serotonin in response to the mental prompt of swallowing a pill containing nothing but sugar and belief. What all this suggests is that the workings of consciousness are both more and less materialistic than we usually think: chemical reactions can induce thoughts, but thoughts can also induce chemical reactions. — Michael Pollan

But the nature of my main work in chemistry can be better represented by more than 280 English publications, of which roughly 200 concern the theory of chemical reactions and related subjects. — Kenichi Fukui

Learning organic chemistry is not any more challenging than getting to know some new characters. The elements each have their own unique personalities. The more you understand those personalities, the more you will be able to read their situations and predict the outcomes of reactions." - Kathleen Nolta, Ph.D., Senior Lecturer in Chemistry — Barbara Oakley

I would like to start by emphasizing the importance of surfaces. It is at a surface where many of our most interesting and useful phenomena occur. We live for example on the surface of a planet. It is at a surface where the catalysis of chemical reactions occur. It is essentially at a surface of a plant that sunlight is converted to a sugar. In electronics, most if not all active circuit elements involve non-equilibrium phenomena occurring at surfaces. Much of biology is concerned with reactions at a surface. — Walter Houser Brattain

There is no agreement on the extent to which metabolism could develop independently of a genetic material. In my opinion, there is no basis in known chemistry for the belief that long sequences of reactions can organize spontaneously
and every reason to believe that they cannot. The problem of achieving sufficient specificity, whether in aqueous solution or on the surface of a mineral, is so severe that the chance of closing a cycle of reactions as complex as the reverse citric acid cycle, for example, is negligible. — Leslie Orgel

It was at the beginning of 1934 while working on the emission of these positive electrons that we noticed a fundamental difference between that transmutation and all the others so far produced; all the reactions of nuclear chemistry induced were instantaneous phenomena, explosions. — Irene Joliot-Curie

All that happens in the human brain is but the result of electro-chemical reactions. Be it of love, hate, of pleasure, of suffering, of imagination, or all other states of mind, sentiment or sickness; the process depends in every case on the chemical reactions produced in the interior of the brain, and the resulting electrical impulses or messages, be they visual, auditory, based on memory, or an interpretation of new events based on elements that one has in the memory. — Rael
