前幾天薔蜜颱風來襲，下雨延著牆壁的裂縫一路走進我房間，直接從天花板吸頂燈流出來。在暴雨的侵襲之下，晚上，燈具開始出現故障的現象。

從一開始的有點閃爍，到後來出現蜂鳴響，再接著出現爆裂聲響，最後一切終於歸於平靜，當然，還有黑暗。
第二天一早起來，我先把吸頂燈給拆下來，一拆下來故障原因立刻一顯無遺：電子開關燒掉了。電子開關本來有個黑色外盒，下圖是拆掉外盒後的裸裝照，明顯的看的出浸水後燒壞的痕跡。

省電燈泡Q&A
Q：省電燈泡的節能省電原理何在？
A：說省電燈泡是「燈泡」並不正確，其實它是以燈泡形狀出現，卻以日光燈發光原理運作的「燈泡型日光燈」，這樣講，大家應該明白它為什麼比較省了吧！

鑒於市售的肥料種類繁多，令許多有意想要進入家庭園藝這一領域的初學者，有如進入五里霧中不知所措，在此特地整理一下肥料的基本資訊及分類，讓初學者可簡易的依照自己的栽培情況選用適合的肥料。
肥料是幫助植物生長的化合物。肥料是施放在土壤中或噴灑在樹葉上，分為無機肥料和有機肥料，肥料中的養分可分為主要營養素和微量營養素兩種，在植物中居有不同的效用及功能。

從一般處理廚餘堆肥的方式來說，可以簡易的分類成兩種形式的堆肥方式：『透氣式堆肥法』和『密閉式堆肥法』；透氣式堆肥法是一種將堆肥的廚餘充分接 觸空氣的堆肥方式，密閉式堆肥法是將廚餘放置於密閉的空間(容器)中，阻絕空氣流通的堆肥方式。雖然兩種運作的原理不同，但是只要操作適宜，都可以製作出 品質優良的有機堆肥。以下則列出兩種堆肥方式的主要差異點:




差異分析/堆肥方式
透氣式堆肥法  (有氧發酵)。
密閉式堆肥法(厭氧發酵)。


分解菌種別
好氧菌。
厭氧菌。


操作空間或器材
開放式的箱、桶或空間，讓廚餘充分接觸空氣。
可密閉的空間或附蓋的箱、桶，將空氣阻絕。


過程中產生的氣味
操作過程中較容易散發出氣味與招引昆蟲，但臭味很低。
發酵過程中會有較重的氣味，但密封好就不會散發難聞氣味和招引昆蟲。


堆肥熟成速度
較快。
較慢。


堆肥成品
乾燥鬆軟的有機堆肥。
略為潮濕的有機肥和液肥。


完熟時的酸鹼度
中性。
偏酸性。

所謂工欲善其事，必先利其器。沒有好工具，做事怎麼有效率呢？

07.08.24 Fri sunny 今天因為有點私事要辦，所以請了個一天的假，也因為請了一天的假，吃到了渴望很久的甜橘。

說實在的，天天上班，其實真的還蠻容易讓人倦怠的，如果上班刷卡時間可以看成工作的熱情，我的熱情大概已經消退了半個小時，從剛開始上班的0810左右刷卡，到現在大概都拖到0830之後才進公司。

於是，反正今天也有點私事要辦，乾脆就請了個一天的假。

上個星期大概是我有生以來最熱的一個星期了，每天台北市的氣溫都超過35度，即使入夜，到了晚上10點，室外氣溫依然是高達30度，在室內，如果不開冷氣，汗水也是狂飆，經過了上一個星期，我想應該沒有任何台北市民會再說溫室效應只是科學家的陰謀論吧！ 下面我之前寫的essay，題目雖然是氣候變遷，可是其實我想說得應該是溫室效應，只是閱卷老師不相信溫室效應真的存在，所以我只好人在屋簷下的改了題目，但是內容基本上還是在談溫室效應。 Human Should Try to Prevent Climate Change      Have you ever heard that polar bears have drowned in the Arctic? In decades ago, this was a ridiculous question. But now, it no longer is. The reason why these tragedies happened is because of the climate change. Think about this question: how we live in where we live? I can think of several reasons. It could because of the convenience of getting water, easy to get food, or cold enough to keep away from bacteria. Just imagine what will happen if climate change? The place we used to live may no longer be the proper place for living. It might never near by the waterside; the soils might not suitable for farming; and known bacteria might mutate to new fatal ones. We built our home based on those environments that we were used to. What should we do if the environment changes? The problem we have here is not the climate is changing or not, but should we do something for the climate change. The answer is obvious, yes. No matter the changing of climate is made by human or just a periodical phenomenon, the truth is that climate change is happening; they affect the whole ecosystem, and will eventually cost a big fortune.      First, let's take a look at climate change happened between now and the past. The biggest difference of the climate change between now and a century ago is structural difference. In the last century, climate changed only in some region on the earth. However, according to the report of Intergovernmental Panel on Climate Change (IPCC), the warmest 11 years of the instrumental record were appeared in the last 12 years (Section: Direct Observations of Recent). In addition, according to Kay (2006), "During the past century, global surface temperatures has increased 1.2 degrees Fahrenheit, according to weather records" (para. 16). Although 1.2 degrees Fahrenheit seems not a big deal, it should be warmer in high latitudes than in low latitudes (Kay, J., 2006, para. 15). Another report written by Tom Simonite (2005) supported this perspective:The ice sheet is shrinking at a rate of about 10% per decade, with Arctic summer temperatures climbing to around 2°C higher than they were 50 years ago. About 1.3 million square kilometres, an area equivalent to three times that of California, have been lost over the past four years. (Section: Going, going, gone, para. 1) This explained why people found polar bears drown. It happens that there are similar cases on other ice. According to Glick (2004), "The famed snows of Kilimanjaro have melted more than 80 percent since 1912" and researchers predict that the glaciers on Himalayan could disappear by 2035 (para. 6).      Climate change has also impacted ecosystem. Pine beetle, which is a kind of harmful insects, makes their living by eating trees. Their population is controlled by weather. They can't survive under cold environment, where the best place for pines' growing. Nevertheless, things have changed. According to Doug Struck (2006), "The weather here has not been cold enough for long enough to kill the beetle" (para. 9), and beetles has destroyed more than 400 million cubic feet of forest (para. 19). Coral reef is another species which sensitive to temperature. Coral reef grows in the ocean where no deep then 30 meters or the temperature no higher than 72 degrees Fahrenheit. Because of climate change, sea level and water temperature have risen around the world. As a result of these, coral reefs are bleaching and dying. What worse is that coral reefs would not die alone. A report of Associated Press states,"The changes will affect countless millions of fish and other marine organisms that depend on the reef" (Henley et al., 2007). Species lost happens not only under the sea, but also on the land. According to Tomas, et al. (2004), "On the basis of mid-range climate-warming scenarios for 2050, that 15–37% of species in our sample of regions will be 'committed to extinction'" (p. 145). Biodiversity is one of the earth's proudest things. However, biodiversity is so weak that is easily to destroy. If we do nothing to prevent climate change, biodiversity will be just a vocabulary in the dictionary in the foreseeable future.      Climate change affects not only ecosystem, but also a financial impact to human beings. As we all know, many viruses are spread by mosquitoes, which have short life spans in the cold region. If temperature climbs, mosquitoes will be more active in these regions, and bring diseases which have never shown before. Sooner or later, we need to pay a lot of money on fighting with diseases. Not to mention some of the mosquitoes bring deadly viruses. There are cities that were built in the mountain because of they have deadly mosquitoes on the level ground. Some of them are already under threatening. Because of the rising temperature we have now, mosquitoes spread to higher altitudes and bring not only diseases but also death. Beside health problem, climate change causes land lost as well. According to Stern (2007), "Many of the world's major cities (22 of the top 50) are at risk of flooding from coastal surges, including Tokyo, Shanghai, Hong Kong, Mumbai, Calcutta, Karachi, Buenos Aires, St Petersburg, New York, Miami and London" (Part II, Chapter 3.5 Land, p. 76). It is not difficult to imagine how large lost we will have if we do nothing to prevent climate change. Stern Review also mentions that if we act now, we need only 1% of global GDP to make our environment better (Section: Summery of Conclusion, para. 5). In contrast, if we do nothing, the overall damage and cost would rise to 5% ~ 20% global GDP (Section: Summery of Conclusion, para. 4).

07.04.20 Fri sunny 今天的天氣其實並不很熱，可是因為習慣了德州的涼爽，氣溫一時升高，還是很不習慣。 我身在的這的地方，是德州的最左上角，暱稱“Texas Panhandle”，根據老師的說法，Panhandle的平均海拔超過3500英呎，也就是超過1000公尺，而陽明山最高點也差不多是1000公尺。在這麼高的地方，一出太陽就可以感受到紫外線的威力，尤其夏天接近了，感受更強。今天下午有事去了學校的活動中心，學校活動中心跟宿舍的距離實在近得很，可是走在太陽下，脖子還是一陣火辣。 離開活動中心，到一個同學I家去討論一下英文，我們討論開始沒有多久，忽然外面停車場傳來一聲爆炸聲響。正好維州校園槍案幾天前（17號）才發生，時機敏感的很，不過因為爆炸聲只一聲就結束了，而且也不是槍聲，我們也就不予理會。 過了五分鐘，台灣人K來敲門，說是同學I的室友韓國人的車子輪胎爆炸。車子停的好好的輪胎會突然爆炸？遇到這種沒聽見過的事情，哪能不快點下去看看。下去一看，左後輪後上緣整個炸開，爆炸的威力還把保險桿給炸彎了。 在場其他台灣人，我、K、還有另一位是N，開始推論起輪胎爆炸原因。K首先說今天天氣很熱，可能是氣溫造成的爆胎，我心裡一陣不相信，今天天氣再熱也沒台灣夏天那麼熱，於是我默默跑去踩車子的前輪試胎壓。一試之下真是大驚訝，韓國人竟然把汽車輪胎打氣打的跟石頭一樣硬，我才開始認同的K的理論。 說起來台灣人就是人好，N聽到我說了驚人的胎壓後什麼都沒說，默默的就去幫韓國人其他輪胎放氣，韓國人自己也開始幫其他輪胎放氣。這時候I說，上次他的車已經爆胎過一次了，我又是一陣大驚訝，這台車韓國人才買不到2個月，竟然已經累積了2次爆胎經驗了，而且還沒學到教訓，依然把胎壓打那麼高！ 在幫輪胎放氣的時候，K告訴我們他正好開車回來，他突然聽到一聲爆炸聲，他嚇了一跳，立刻把車子靠邊停下，往爆炸聲響發生的停車場一看，就看到韓國人的車後冒煙，他才敢靠近看，也發現原來是輪胎爆炸。我們才知道原來K是目擊者，他剛說是他眼見為憑的事實。 後來我們又開始討論起怎麼換輪胎，I說後車廂有工具，可是不會用。這時候韓國人一直叫I打電話請其他台灣人幫忙，我聽了感覺有點差，我們不斷的跟他說車子既然有工具就一定可以用，韓國人怎麼就是不肯把工具拿出來讓我們看看，不肯也就算了，還用這麼差的口氣請人幫忙，N這時候又默默的走上樓說要幫他找電話。韓國人又跟I爭執了一下之後，韓國人終於願意把工具拿出來看看，一看之下，根本就是很簡單的隨車工具，我操作了一下給他看，他也不說聲謝就回頭上樓拿了一付太陽眼鏡戴上，自己開始動手了起來。
