science[5saiEns]n.科学, 自然科学, 理科（sci+ence）

sci-源自拉丁语词根，表“知道”，相当于英语中的know

-ence名词后缀

也就是说，您只要掌握sci就基本上可以轻松掌握science, conscience, omniscience：

conscience[5kCnFEns]n.良心, 道德心（con+sci+ence）

omniscience[Cm5nisiEns]n.全知, 全知者, 上帝(omni+sci+ence)

omni-[5RmnI]源自拉丁语，表示“全部, 总”之义

omnibus[5CmnibEs]n.公共汽车, 公共马车, 精选集adj.综合性的, 混合的, (包括)多项的（omni+bus）

源自 拉丁语 [所有的]，omnis的与格复数 [一切]

特别提示：把英语单词拆解成各自独立的字母去“背”是十分愚蠢的行为，如果您的孩子被误导或被强迫这样做，他极可能终身都无法真正学会英语。

什么是“科学”，请大家大概地读一读下面的内容：

Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.^[1]

In an older and closely related meaning (found, for example, in Aristotle), "science" refers to the body of reliable knowledge itself, of the type that can be logically and rationally explained (see History and philosophy below).^[2]

Since classical antiquity science as a type of knowledge was closely linked to philosophy.

In the early modern era the words "science" and "philosophy" were sometimes used interchangeably in the English language.

By the 17th century, natural philosophy (which is today called "natural science") was considered a separate branch of philosophy.^[3]

natural philosophy n.自然哲学(旧时用以指自然科学,尤指物理学)

However, "science" continued to be used in a broad sense denoting reliable knowledge about a topic, in the same way it is still used in modern terms such as library science or political science.

In modern use, "science" more often refers to a way of pursuing knowledge, not only the knowledge itself.

It is "often treated as synonymous with 'natural and physical science', and thus restricted to those branches of study that relate to the phenomena of the material universe and their laws, sometimes with implied exclusion of pure mathematics.This is now the dominant sense in ordinary use."^[4]

This narrower sense of "science" developed as scientists such as Johannes Kepler, Galileo Galilei and Isaac Newton began formulating laws of nature such as Newton's laws of motion.

law of nature n.自然法则,自然定律

In this period it became more common to refer to natural philosophy as "natural science".

natural science n.自然科学

Over the course of the 19th century, the word "science" became increasingly associated with the scientific method, a disciplined way to study the natural world, including physics, chemistry, geology and biology.

It is in the 19th century also that the term scientist was created by the naturalist-theologian William Whewell to distinguish those who sought knowledge on nature from those who sought knowledge on other disciplines.

The Oxford English Dictionary dates the origin of the word "scientist" to 1834.

This sometimes left the study of human thought and society in a linguistic limbo, which was resolved by classifying these areas of academic study as social science.

Similarly, several other major areas of disciplined study and knowledge exist today under the general rubric of "science", such as formal science and applied science.

科学并不是万能的上帝，它还有很多未知的领域，还有很多科学无法解释的东西。从牛顿、爱因斯坦到今天的霍金，科学家们在泥泞的道路上不断地探索、前进。当然科学家也犯了不少错误，比如关于“混沌”的固执和死不悔改。请参考《艾伦·图灵——用生命见证主流科学家狂妄无知的悲剧性人物》。

了解了“科学”才可以更清楚地了解“伪科学”。那什么是“伪科学”呢？

pseudoscience[(p)sj u:dEu5saiEns]n.假科学, 伪科学（pseudo+science）

pseudo-表示“伪, 假拟, 虚”之义

建议大家先读一读《pseudo（假的, 冒充的，伪造的）≠“没用”》，然后再大概地读一读下面的内容：

Pseudoscience is a claim, belief, or practice which is presented as scientific, but does not adhere to a valid scientific method, lacks supporting evidence or plausibility, cannot be reliably tested, or otherwise lacks scientific status.^[1]

or otherwise 或相反

所谓“伪科学”也就是无法用现有的科学方法证实的“主张、信仰、行为”。如果我们不能证明“科学是完美无缺的真理”，也就无法证明“所有没有经过不完美的科学证明的东西都是谎言”。

就像当年的“日心说”和20世纪的“混沌理论”都曾经被说成是“伪科学”。而事实上，它们在现在都被认为是真正的科学。

Pseudoscience is often characterized by the use of vague, contradictory, exaggerated or unprovable claims, an over-reliance on confirmation rather than rigorous attempts at refutation, a lack of openness to evaluation by other experts, and a general absence of systematic processes to rationally develop theories.

A field, practice, or body of knowledge can reasonably be called pseudoscientific when it is presented as consistent with the norms of scientific research, but it demonstrably fails to meet these norms.^[2]

Science is also distinguishable from revelation, theology, or spirituality in that it offers insight into the physical world obtained by empirical research and testing.^[3]

至少到目前为止，科学依然没有搞清楚什么是“物质”。

请参考《中科院院士朱清时 佛法解释物理学（科学家千辛万苦爬到山顶时，佛学大师已经在此等候多时了！）》。

Commonly held beliefs in popular science may not meet the criteria of science.^[4]

 "Pop" science may blur the divide between science and pseudoscience among the general public, and may also involve science fiction.^[4]

Pseudoscientific beliefs are widespread, even among public school science teachers and newspaper reporters.^[5]

The demarcation problem between science and pseudoscience has ethical political implications, as well as philosophical and scientific issues.^[6]

Differentiating science from pseudoscience has practical implications in the case of health care, expert testimony, environmental policies, and science education.^[7]

Distinguishing scientific facts and theories from pseudoscientific beliefs such as those found in astrology, medical quackery, and occult beliefs combined with scientific concepts, is part of science education and scientific literacy.^[8]

The term pseudoscience is often considered inherently pejorative, because it suggests something is being inaccurately or even deceptively portrayed as science.^[9]

Accordingly, those labeled as practicing or advocating pseudoscience normally dispute the characterization.^[9] See also List of topics characterized as pseudoscience.
