Why Computers are the Papers of the Future

兒子國一社會科的作業 

Paper have been around for hundreds of years, and is important to a variety of daily task. However, paper is easy to break and tear apart, and is easy to lose whatever information may be on the paper, whether it is a note to yourself or an assignment for school. 

When you write out ideas on a piece of paper, there will only be a copy, and if you were to lose it, the information will be lost forever, however, with today’s cloud technology, the piece of work will likely never disappear, and you will always be able to access it from anywhere.

Paper, is also very heavy when compared to the amount of data that can be stored on a hard　drive, or even the non-existent weight of cloud storage. For example if one wanted to bring books to read on a trip, it would be much lighter if the person brought an eReader, such as a kindle, which is lighter than the weight of the actual books.

It has also been proven that tablets and computers are better for assignment, as many schools in the United States had been started using ipads and surfaces instead of sheets of paper. A teacher even said that “It is so much easier to keep track of assignment.” Students have also reported that using surfaces is a more superior way to paper in terms of drawing, as modern drawing application such as Microsoft’s fresh paint software, allows for realistic drawing, as if on paper. Students also stated that writing on a tablet using a stylus was like writing on paper, but smoother. Also, tablets in education is also more eco–friendly, as the reusability of a tablet is much greater than those of a piece of paper. Tablets also allow students to organize their work more easily than using paper, where paper is crumbled up easily, and is often lost, while with computers and cloud storage, the information will be unlikely to be gone.

Even though paper has been proven helpful, it is beginning to be taken over by computers, which allow for more precise way to write down information. This does not mean that paper has completely loose its use, it is just that computers are better than paper at some aspects, such as in education and other purposes where computers allow for easier organization and better usability. 

機器人倉儲系統：結合跨領域知識的 Kiva Systems

網購商店如何完成妳的訂單？可以觀看 Amazon.com 的例子

這種傳統的運送帶和人取物方式有許多缺點，註 1 的論文列舉了一些 (costly, long design cycles, inflexible, not expandable, batch processing, fixed locations, manual reslotting)。網路泡沫化 (dot-com bubble) 時期的 Webvan 便因此破產。

Art Institute of Vancouver

四年 9 萬美金的學費 

朋友考慮讓其小孩到此校念書，說明其實作課程有 PC 和 Mac 兩種平台、和諸多的商用軟體；追問下，得知該校四年的學費為 9 萬美金。

上網查詢其課程大綱，以 Game Programming 為例，其中多門的數學課程在我教的課程中有教。

以敝校的數位內容創作學士學位學程為例，師資和 Art Institute of Vancouver 相比，絲毫不遜色。而且四年學費才 42 萬新台幣，不到美金 1.5 萬元。 

如同我先前的 blog (台灣的大學學費) 所言，以目前的收費標準，無法提供足夠的軟硬體設備和支援，以增進學生的學習成效。所以台灣需要適當地提高大學學費，以提高教學的品質。

三洋洗衣機的軟洗精注入口

怎麼會如此設計？

原先的洗衣機底盤漏水，因無備料所以無法維修。因為忙碌，打電話給原先的電器行推薦，問清楚了大小和品牌，便下訂單。

等到我隔天使用時傻眼了，舊洗衣機的軟洗精注入口是固定在洗衣粉盒的右邊，現在卻是固定在洗衣機的旋轉槽邊，有時轉到如下圖中所示的位置，請問要如何將軟洗精倒進去？

這種因角度不對而無法倒軟洗精的機會有一半。最近已經連續五次發生此情況，機率是 1/32。

對消費者的建議是買某些東西一定要親眼看見再買。
對零售商的而言，不要只推荐利潤好的廠牌，不然一次就怕到了。
對設計的三洋公司，我真的不知道為什麼會推出這種產品？

2015/11/4：一年左右，裡外兩條水管都破掉！二年左右，就已經無法使用！這真的是台灣製的品質？

一元二次方程式

朋友小孩的問題和博幼社會福利基金會 

該基金會的免費數學教材有很好的說明，而且練習題都有附解答。

以 x^2 － 8 x ＋ 12 ＝ 0 為例，考慮『十字交乘法』，因 (x－2)(x－6)＝0，所以其解為 2 和 6。該文章也列舉了許多方法；不過，我習慣以一種核心方法來解決問題，所以還是要回到根本的『平方差公式』法

得到相同的答案；其實，上述文章中的所有方法都可以用平方差公式處理之，考試中使用此策略可以避免搞混。

上述文章中有許多的應用題型，進一步的例子可以參見以下的英文網站 (1，2，3)。 

我知道有些人對李家同教授有不同的看法；但是，他真的是默默地做了很多事。
