Chemistry
Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron(s); ionic bonds, in which a compound donates one or more electrons to another compound to produce ions (cations and anions); hydrogen bonds; and Van der Waals force bonds.

Organic Chemistry
Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes many physical and chemical methods to determine the chemical composition and the chemical constitution of organic compounds and materials. Study of properties includes both physical properties and chemical properties, and uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behavior of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes probing their scope through use in preparation of target compounds (e.g., natural products, drugs, polymers, etc.) by chemical synthesis, as well as the focused study of the reactivities of individual organic molecules, both in the laboratory and via theoretical (in silico) study.

We can no more have exact religious thinking without theology, than exact mensuration and astronomy without mathematics, or exact iron-making without chemistry,
John Hall (Presbyterian pastor) (1895) Dictionary of Burning Words of Brilliant Writers p. 580.
Chemistry
It is a mistake to confound Alchemy with Chemistry. Modern Chemistry is a science which deals merely with the external forms in which the element of matter is manifesting itself. It never produces anything new. We may mix and compound and decompose two or more chemical bodies an unlimited number of times, and cause them to appear under various different forms, but at the end we will have no augmentation of substance, nor anything more than the combinations of the substances that have been employed at the beginning. Alchemy does not mix or compound anything, it causes that which already exists in a latent state to become active and grow. Alchemy is, therefore, more comparable to botany or agriculture than to Chemistry; and, in fact, the growth of a plant, a tree, or an animal is an alchemical process going on in the alchemical laboratory of nature, and performed by the great Alchemist, the power of God acting in nature.
Franz Hartmann. (1890) In the Pronaos of the Temple of Wisdom, containing the History of the True and the False Rosicrucians. p. 129

Once you are there you'll be like a drop of water in a piece of rock crystal- your medium will dignify your commonness.
Thomas Hardy, A Pair of Blue Eyes, 1873
Global climate models that improve the accuracy of seasonal predictions have several limitations. An EU initiative used a large number of climate model simulations to optimise forecasts.
