=== Article of the Week <font size=1>[ [[CZ:Article of the Week|about]] ]</font> ===
'''Homeopathy''' or '''homoeopathy''' is a system of [[Complementary and Alternative Medicine|alternative medicine]].  The term derives from  the Greek ''hómoios'' (similar) and ''páthos'' (suffering). The underlying concept of homeopathy is "like cures like" and is based on "the principle of similars", which asserts that substances known to ''cause'' particular symptoms can also, in low and specially prepared doses, help to ''cure'' diseases that cause similar symptoms. Some principles of homeopathy have been utilized in various forms in various medical systems for thouands of years in many diverse cultures, but they were first methodically set out by a German physician, [[Samuel Hahnemann]] (1755–1843), who observed that a medicine sometimes evoked symptoms similar to those of the illness for which it was prescribed. Related maxims such as the "Law of similars" are common in anthropological literature.

=== New Draft of the Week <font size=1>[ [[CZ:New Draft of the Week|about]] ]</font> ===
Across a wide range of cultures some common themes recur, among them '''sympathetic magic'''.  It attempts to use a symbol of some notable event to cause the full power of that event to manifest itself, most notably as seen in [[cargo cult]]s.  Classic examples of cargo cults, although they had been observed much earlier, played out in [[Melanesia]] during the [[Second World War]]: natives would see desirable "cargo" come out of an airplane, or, perhaps in a more modest fashion, cold beer from a refrigerator. They would subsequently construct wooden replicas of airplanes or refrigerators, hoping that, with the right invocation, they would then open their own door and find the same precious cargo.
Where the goal of the cargo cult is to invoke and create, another aspect of sympathetic magic is to protect and control. In a healing rite from Jewish mysticism, a person who wanted bleeding to stop would sit under a drain, as others poured water over him, all saying a formula that predicted that as the water flow stopped, so would the blood flow cease.<font size=1>[[sympathetic magic|['''more...''']]]</font>

Featured Article: Nuclear power reconsidered

After decades of failure to slow the rising global consumption of coal, oil and gas,[1] many countries have proceeded as of 2024 to reconsider nuclear power in order to lower the demand for fossil fuels.[2] Wind and solar power alone, without large-scale storage for these intermittent sources, are unlikely to meet the world's needs for reliable energy.[3][4][5] See Figures 1 and 2 on the magnitude of the world energy challenge.

Nuclear power plants that use nuclear reactors to create electricity could provide the abundant, zero-carbon, dispatchable[6] energy needed for a low-carbon future, but not by simply building more of what we already have. New innovative designs for nuclear reactors are needed to avoid the problems of the past.

Fig.1 Electricity consumption may soon double, mostly from coal-fired power plants in the developing world.[7]

Issues Confronting the Nuclear Industry

New reactor designers have sought to address issues that have prevented the acceptance of nuclear power, including safety, waste management, weapons proliferation, and cost. This article will summarize the questions that have been raised and the criteria that have been established for evaluating these designs. Answers to these questions will be provided by the designers of these reactors in the articles on their designs. Further debate will be provided in the Discussion and the Debate Guide pages of those articles.

Footnotes

  1. ↑ Global Energy Growth by Our World In Data
  2. ↑ Countries, organizations, and public figures that have reconsidered their stance on nuclear power are listed on the External Links tab of this article.
  3. ↑ Pumped storage is currently the most economical way to store electricity, but it requires a large reservoir on a nearby hill or in an abandoned mine. Li-ion battery systems at $500 per KWh are not practical for utility-scale storage. See Energy Storage for a summary of other alternatives.
  4. ↑ Utilities that include wind and solar power in their grid must have non-intermittent generating capacity (typically fossil fuels) to handle maximum demand for several days. They can save on fuel, but the cost of the plant is the same with or without intermittent sources.
  5. ↑ Mark Jacobson believes that long-distance transmission lines can provide an alternative to costly storage. See the bibliography for more on this proposal and the critique by Christopher Clack.
  6. ↑ "Load following" is the term used by utilities, and is important when there is a lot of wind and solar on the grid. Some reactors are not able to do this.
  7. ↑ Fig.1.3 in Devanney "Why Nuclear Power has been a Flop"
