| ARTICLES RELATED TO systematics |  |  |  | systematics: Encyclopedia II - Jacob Neusner - ImpactNeusner’s enterprise has been aimed at a humanistic and academic reading of classics of Judaism, yet with full regard for their specific statements to their own world. He demonstrates how people wrote these books as a way of asking and answering questions that we can locate and understand. According to Neusner, when we can find those shared and human dimensions of documents we can relate classic writings to a world we understand and share. That imputes a common rationality to diverse authorships and ages – theirs and ours – and, Neusner believes, expresses the fundamen ...

Alcohol - Systematic names.
In the IUPAC system, the name of the alkane chain loses the terminal "e" and adds "ol", e.g. "methanol" and "ethanol". When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the "ol": propan-1-ol for CH3CH2CH2OH, propan-2-ol for CH3CH(OH)CH3. Sometimes, the position number is written before the IUPAC name: 1-propanol and 2-propanol. If a higher priority group is present (such as an a ...

|  |  |  | systematics: Encyclopedia II - Expository preaching - Advantages and Disadvantages of Expository PreachingThe main advantage of systematic expository preaching is that the preacher will never be lost for a subject for his or her sermon, since few preachers have ever preached through the entire Bible in their lifetime or with one congregation. Should they be so fortunate to finish the entire Bible with the same congregation, many years will have passed with (hopefully) lots of new faces in the congregation, so they can start ...

| |  |  |  | systematics: Encyclopedia II - Theology - Divisions of theologyTheology can be divided up in any number of ways. Many of these divisions have originated in the study of the Christian religion, although some have been adapted and extended to apply to other religions, or to the study of multiple religions.
The most established distinctions are Systematic Theology, Biblical Studies/Biblical Theology, Historical Theology and Pastoral Theology.
Theology can also be divided up into :
Academic subdisciplines;

Theology - Classical Greek theology c.700 BC to 323 BC.
Various forms of systematic and philosophical reflection on Ancient Greek religion and Greek mythology arose in the classical period - from Hesiod's attempts to organise the diverse materials of mythology into a unified Theogony to the more properly philosophical analysis reportedly carried out by Socrates.
Plato's Timaeus and Aristotle's Metaphysics Book Lambda are two of the most influential writings of Classical Greek theology.

|  |  |  | systematics: Encyclopedia II - Alcohol - StructureThe functional group of an alcohol is a hydroxyl group bonded to an sp3 hybridized carbon. It can therefore be regarded as a derivative of water, with an alkyl group replacing one of the hydrogens. If an aryl group is present rather than an alkyl, the compound is generally called a phenol rather than an alcohol. The oxygen in an alcohol has a bond angle of around 109° (c.f. 104.5° in water), and two nonbonded electron pairs. The O-H bond in methanol (CH3OH) is around 96 picometres long.

|  |  |  | systematics: Encyclopedia II - Alcohol - UsesAlcohols are in wide use in industry and science as reagents, solvents, and fuels. Ethanol and methanol can be made to burn more cleanly than gasoline or diesel. Because of its low toxicity and ability to dissolve non-polar substances, ethanol is often used as a solvent in medical drugs, perfumes, and vegetable essences such as vanilla. In organic synthesis, alcohols frequently serve as versatile intermediates.
Ethanol is also commonly used in beverages after fermentation to promote flavor or induce a euphoric intoxication commonly kn ...

|  |  |  | systematics: Encyclopedia II - Alcohol - Physical and chemical propertiesThe hydroxyl group generally makes the alcohol molecule polar. Those groups can form hydrogen bonds to one another and to other compounds. Two opposing solubility trends in alcohols are: the tendency of the polar OH to promote solubility in water, and of the carbon chain to resist it. Thus, methanol, ethanol, and propanol are miscible in water because the hydroxyl group wins out over the short carbon chain. Butanol, with a four-carbon chain, is moderately soluble because of a balance between the two trends. Alcohols of five or more carbons (Pentanol and higher) are effecti ...

|  |  |  | systematics: Encyclopedia II - Alcohol - ToxicityAlcohols often have an odor described as 'biting' that 'hangs' in the nasal passages. Ethanol in the form of alcoholic beverages has been consumed by humans since pre-historic times, for a variety of hygienic, dietary, medicinal, religious, and recreational reasons. While infrequent consumption of ethanol in small quantities may be harmless or even beneficial, larger doses result in a state known as drunkenness or intoxication and, depending on the dose and regularity of use, can cause acute respiratory failure or death and with ch ...

Several methods exist for the preparation of alcohols in the laboratory.
Primary Alkyl halides react with aqueous NaOH or KOH mainly to primary alcohols in nucleophilic aliphatic substitution. (Secondary and especially tertiary alkyl halides will give the elimination (alkene) product instead).
Aldehydes or ketones are reduced with sodium borohydride or lithium aluminium hydride. (after an acidic workup)

Number theory - Early history.
Number theory was a favorite study among the Ancient Greeks, who were aware of the Diophantine equation concept in numerous special cases. It revived in the sixteenth and seventeenth centuries, in Europe, with François Viète, Bachet de Meziriac, and especially Fermat, whose infinite descent method was the first general idea for dealing with diophantine questions. In the eighteenth century Euler and Lagrange made major contributions.

Exhortatory, biographical, evangelistic, and charismatic preaching are subsets of topical preaching.
Expository preaching differs from topical preaching in that it will lead preacher and congregation to concentrate on a particular Bible passage and sequentially work thr ...

|  |  |  | systematics: Encyclopedia II - Expository preaching - Relative importance of expository preachingThere has been some discussion among preachers of the relative importance of expository preaching. The great majority of Christians follow the conventional understanding that there are four bases for faith: the Bible, the tradition of the church, the individual's religious experience, and human reason. However the emphasis put on each of these varies between denominations and congregations.
In particular, some churches give Scripture the dominant position over all other sources of religious understanding. This is most common in ...

|  |  |  | systematics: Encyclopedia II - Expository preaching - Expository Preaching and the Seeker MovementThe seeker movement stresses the use of topical preaching in an attempt to make the Bible "relevant" to the congregation, specifically visitors with little or no recent church background. As such, expository preaching is very seldom used, and if so it may cover a book of the Bible at a very surface level (no more than 4-8 weeks total). Many verses that do not neatly fall into a topic, or where the topic (such as the Old Testament sacrificial system) is not considered "relevant" to the needs of the congregation, are thus not covered within the seeker movement.

|  |  |  | systematics: Encyclopedia II - Expository preaching - Scriptural basis for expositionFor those who believe that the dominant source of Christian understanding is the bible, it may seem obvious that expository preaching should be essential (though this is not the case with the seeker movement). Nonetheless the logic of their position demands that preaching itself should have a scriptural warrant.
The biblical basis for expository preaching can be found in many places in the Bible. 2 Timothy 3:16-17 is perhaps the most important, for it states that Scripture is "breathed out by God", which means that the Bible is actual ...

While studying, they will also be praying that God will reveal to them the proper meaning of the text, and that the hearts and minds of the congregation will be changed by it (believing that they do not have ...
