History rubs shoulders and often overlaps with many other areas of research, from myths and epics to the social science, including economics, politics, biography, demography, and much else besides. Some histories are almost pure narratives, while others go in for detailed, tightly-focused analyses of, for example, the parish records of a Cornish village in the 16th century.
There are many kinds of pond, but nearly all are small bodies of shallow, stagnant waterin which plants with roots can grow. Water movement is slight and temperatures fluctuate widely. The wealth of plants ensures that during daylight hours oxygen is plentiful. However, at night, when photo synthesis no longer takes place, oxygen supplies can fall very low.
Before the time of Alexander the Great, the only eastern people who could be compared with the Greeks in the fields of science and philosophy were from the Indian sub-continent. However, because so little is known about Indian chronology, it is difficult to tell how much of their science was original and how much was the result of Greek influence.
While far fewer people these days write letters and therefore have less use for stamps, there are still a few categories of stamp which attract collectors. Stamps in common use for an indefinite period - until the price goes up - are called "definitive" issues, while a more collectible type of stamp is the "commemorative" issue, honoring people, events and anniversaries.
In the second quarter of the 19th century, a rapidly growing middle class created a great demand for furniture production. Yet at this stage, while machines were used for certain jobs, such as carved decoration, there was no real mass production. The extra demand was met by numerous wood workers. Mass production came later and the quality of domestic furniture declined.
In the Middle Ages, the design and use of flags were considered a means of identifying social status. Flags were, therefore, the symbols not of nations, but of the nobility. The design of each flag resembled the "devices" on the noble's Coatof Arms, and the size of the flag was indication of how high the owner stood in the nobility.
