David A. Evans (January 11, 1941 – April 29, 2022) [1] [2] [3] was an American chemist who was the Abbott and James Lawrence professor of chemistry at Harvard University. [4] [5] He was a prominent figure in the field of organic chemistry and his research focused on synthetic chemistry and total synthesis, particularly of large biologically active molecules.
The last edition of The Harvard Classics printed by P.F. Collier & Son (then a subsidiary of Crowell Collier & Macmillan, Inc.) was the 63rd printing in 1970 of a 22-volume called the "Great Literature Edition" in green fibrated (essentially bonded) leather with 22K decor that sold for $3.78 per volume ($1 each for the first three volumes).
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Curriculum mapping is a procedure for reviewing the operational curriculum [1] as it is entered into an electronic database at any education setting. It is based largely on the work of Heidi Hayes Jacobs in Mapping the Big Picture: Integrating Curriculum and Assessment K-12 (ASCD, 1997) and Getting Results with Curriculum Mapping (2004, ASCD).
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
LibreTexts' current primary support is from the 2018 Open Textbook Pilot Program award from the Department of Education Organization Act. [7] [10] [5] [11] FIPSE [12] Other funding comes from the University of California Davis, the University of California Davis Library, [5] and the California State University System both through MERLOT and its Affordable Learning Solutions (AL$) program.
In chemistry, a mole map is a graphical representation of an algorithm that compares molar mass, number of particles per mole, and factors from balanced equations or other formulae. [1] They are often used in undergraduate -level chemistry courses as a tool to teach the basics of stoichiometry and unit conversion .
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
