Lecture08
The document discusses the concept of correlation as a way to quantify the association between two variables. It explains that correlation standardizes the covariance between two variables by dividing by the product of their standard deviations. This results in a correlation value between -1 and 1, where values closer to -1 or 1 indicate a stronger linear relationship between the variables. The correlation coefficient provides a standardized way to measure the strength and direction of association between two quantitative variables.
Measurement
The document discusses various concepts related to measurement and error including:
- Defining accuracy as closeness to the true value and precision as reproducibility of measurements.
- Types of errors such as determinate/systematic errors which can be corrected and indeterminate/random errors which average out with multiple trials.
- Assessing total error by treating a reference standard as a sample and calculating differences from the reference value.
- Expressing accuracy and precision using terms like mean, percent error, range, standard deviation, and percent coefficient of variation.
Periodic table
The document discusses key concepts from the periodic table including its organization, elements, trends, and measurements. It provides information on Dmitri Mendeleev's creation of the first periodic table and how it is organized today. The periodic law and trends in atomic radius, ionization energy, electronegativity, and electron affinity across and down the table are also summarized.
Med Apps Nuclear Science
Radiation can be ionizing or non-ionizing, with ionizing radiation capable of damaging biological tissues. Absorbed radiation dose is measured in units like rads and grays, while biological effectiveness is measured using quality factors ranging from 1 to 20 depending on radiation type. Exposure levels are regulated to limit health risks like cancer, with annual limits of 0.5 rem for the public and 5 rem for radiation workers.
Iweb
This document provides an overview of using iWeb in the classroom for creating websites. It discusses the National Educational Technology Standards, what iWeb is, ways to start using it like creating a class website with pages and media. Alternatives like content management systems and wikis are mentioned. Considerations for using iWeb vs wikis are provided. It also discusses where files are stored, having multiple iWeb sites, and provides an assignment to create a website with specific elements like pages, text, links, images, movies and widgets.
Work And Simple Machines
Work is defined scientifically as a force causing an object to move in the direction of the force. Simple machines like levers, pulleys, and inclined planes allow people to do work more easily by increasing force or distance of movement. They provide mechanical advantage by changing the direction or magnitude of force. Common simple machines are the lever, wheel and axle, inclined plane, wedge, screw, and pulley. Each machine trades off either force or distance depending on its class.
Thiols & sulfides
Thiols are sulfur analogs of alcohols and are also called mercaptans. Sulfides are sulfur analogs of ethers and are also known as thioethers. Thiols and sulfides have lower boiling points and are less soluble in water than other alcohols and ethers. They also show little association through hydrogen bonding. Common thiols include those that give onions and garlic their smell, while common sulfides include metal sulfides like silver sulfide, mercury sulfide, and lead sulfide. Thiols and sulfides are used in industries like oil, gas, pulp and paper.
What Is Physics
Physics is the science of matter, energy, space, and time that studies the interactions between physical systems. It aims to describe natural phenomena through basic laws and quantities derived from experimentation. Some key topics in physics include mechanics, waves, thermodynamics, electricity, nuclear physics, and quantum mechanics.
環宇電台-科技下一站:新公民時代 社群網站行銷-傑克老師郭賢佑執行長採訪
日前公民聯盟號召25萬人上街遊行，就是在Facebook上面發起運動，由此可知現代社會，社群網站扮演著重要的角色，不僅成為每個人生活中的一部分，甚至透過社群網站的高度串連與分享，變成公民發起運動與評論的公共平台。
(1)網路的普及，帶動社群網站的興起，其中Facebook成為全球擁有會員數最多的網站平台，這股風潮興起的原因?
(2)科技快速變化，其中Facebook不僅發展長達十年，全球擁有超過十億個用戶，甚至在去年上市募股，談談Facebook的經營模式與成功經驗?
(3)隨著行動裝置的發達，許多人甚至一整天都在FB上面關注好友的訊息，按讚還成為時下年輕人用語的一種，要如何操作與應用FB來培養粉絲建立個人社交人脈?
(4)網路行銷效益無窮，各大企業紛紛建立粉絲專頁，除建立品牌知名度外，也藉此開發客戶名單來拓展業務，該如何藉由FB來經營長期客戶及高度忠誠度?
(5)Facebook算是開放式的社群平台，留言分享也都會透過一傳十、十傳百的力量散播出去，因此隱私權和安全性的爭議也不斷發生，有關個人該如何保障自己的權益?
(6)雖然Facebook中只有好友可以關注動態，不過透過分享的方式，也讓訊息無遠弗屆，就像是日前公民聯盟號召25萬人上街遊行，就是透過Facebook發起，有關社群網站對現代社會的影響?
(7)社群網站不斷的汰舊換新，沒有人知道Facebook的風潮還會持續多久，有關社群網站的未來方向發展?
最後，社群網站正在逐步改變現代人的人際交流模式，並相信未來將會透過不斷的精進與淘汰，進化成新的模式出現，不過社群網站的興起，也意味著新公民時代的來臨，讓每個人都能創造與經營個人發聲的平台。

網路科技x社運@庶人之亂：青年行動者培力交流營
網路科技在社運中可以扮演什麼角色？除了社交媒體之外，參與式民主、資料驅動的社運行動將是具有潛力的路徑。g0v.tw零時政府社群從資訊透明出發，降低參與社會議題門檻，也希望逐漸與社運有橋接的基點，找到新的行動方向。

YANG DESIGN User Study Lab: 4 Consumption Trends of China’s Post80&90s
China’s Post80&90s are also marked as the Generation Y. In which social content did they grow up? Who are they and how will they become? And how will their shop for their home? The Consumption Trends of China’s Post80&90s Report is a study project by YANG DESIGN and is commissioned by TrendsHome, the home magazine with largest distribution in China. The study combines methods of desktop research, opinion leader interview and online questionnaire. It reviews the politic, economic, social and technological backgrounds, summarizes the home consumption pattern and lifestyle cluster groups. 4 macro trends are predicted and presented with future scenarios.
