The document lists various geometric shapes such as polygons, ellipses, and 3D shapes. It also defines reflective symmetry as folding a shape in half and it looking the same, and translation as moving every point of a shape the same distance in the same direction without rotating or resizing. Tessellation is described as shapes arranged with no overlaps or gaps to continue indefinitely.

Frontiers North presentation for Canadian Marketing Association, Manitoba Cha...John Gunter
Frontiers North Adventures (FNA) is a Manitoba-born and -bred company that specializes at hosting international travellers in Canada's north on expert-guided group tours. FNA sells to international, niche markets through a global network of tour operators and also directly to guests. During his talk, John will discuss the importance of Corporate Social Responsibility as well as challenges securing "share of the suitcase", competing with adventure and photographic destinations from Antarctica to Svalbard and tourism destinations from Rome to Banff.
This document discusses evaluating different types of information sources, including academic publications, newspapers/magazines, and websites. It provides guidance on how to evaluate these sources based on factors like author reputation, date of publication, biases, methodology, and conclusions. Academic publications are peer-reviewed sources intended for researchers that should be evaluated based on quality criteria. Newspapers/magazines vary in quality and are aimed at general audiences. Websites require careful evaluation of credibility and information quality. Databases and library resources can provide reliable sources for research.
Hannibal was one of the greatest military generals who, at age 9, was brought by his father to Spain to fight in a war against Rome that lasted 20 years. Hannibal created an army of 50,000 men after his brother died to continue fighting the Romans, who ensured their army numbered 80,000 men and ultimately destroyed Hannibal's forces.
The document summarizes key events and social changes in British history from the earliest settlers to the First World War:
- The earliest settlers arrived around 2300 BC before the Celtic tribes migrated in the 5th century BC, establishing tribal systems. The Romans invaded in 43 AD and controlled Britain until the 5th century AD.
- Anglo-Saxon invasions beginning in the 5th century led to the establishment of a feudal system. Vikings invaded from the 8th century. The Norman invasion of 1066 introduced Norman rule and feudalism.
- The Industrial Revolution transformed social and economic structures as people moved to cities for factory work. Political reforms expanded voting rights through the 19th century. World War I
Marketplace 3.0 - Masatada Kobayashi / Co-fundador da RakutenRakuten Brasil
This document discusses the empowerment philosophy and growth of Rakuten, a Japanese e-commerce company. It outlines Rakuten's origins in 1997 with 5 employees and its growth to over 10,000 employees and a market capitalization of $17 billion by 2013. The document also summarizes Rakuten's core e-commerce strategy of building a membership-based internet business and its efforts to support merchants through technology and consulting services.
The document discusses Belgium's patent income deduction tax policy, which allows companies to deduct 80% of income from self-developed or acquired patents from their taxable income, resulting in an effective tax rate of up to 6.8% on patent income. The deduction applies to Belgian companies and foreign companies with Belgian branches that develop patents in Belgium or abroad. It aims to incentivize research and development activities in Belgium.
The document summarizes photosynthesis and the organelle where it takes place, the chloroplast. It explains that photosynthesis uses carbon dioxide, water, and sunlight to produce oxygen and energy in the form of sugar. The two main parts of photosynthesis are the light reactions, where light energy is converted to chemical energy, and the Calvin cycle, where carbon is fixed into sugars. Photosynthesis occurs in the chloroplasts within plant cells, which contain chlorophyll pigments, thylakoid membranes, and a surrounding fluid-filled area called the stroma.

10. 信息与熵
1948年香农在Bell System Technical Journal上发表了《A Mathematical Theory
of Communication 》
香农理论的重要特征是熵(entropy)的概念，他证明熵与信息内容的不确定程度
有等价关系。
熵曾经是波尔兹曼在热力学第二定律引入的概念，我们可以把它理解为分子运动
的混乱度。
信息熵就以比特(bit)为单位。今天在电脑和通信中广泛使用的字节(Byte)、KB、
MB、GB等词都是从比特演化而来。“比特”的出现标志着人类知道了如何计量信
息量。
11. 香农对信息的定义
信息量定义为随机不定性程度的减少。
信息是用来减少随机不定性的东西。
或香农逆定义：信息是确定性的增加 。
为何要计量信息量？
不能度量，就无法控制，也就无法管理
—— If you can't measure it, you can neither control nor manage it.
14. 例：兰德公司报告
朝鲜战争与兰德咨询公司故事。朝鲜战争前，兰德公司向美国国防部推销一份秘
密报告，其主题词只有7个字，要价150万美元。
美国国防部认为是敲诈，不予理睬，结果"在错误的时间，在错误的地点，与错
误的敌人进行了一场错误的战争"。
战争结束之后，国防部才想起那份报告，要来一看，追悔莫急。问题：那7个字
是什么？
China will send troops to North Korea
