Our professor showed us the video in class, but he didn't really go through this phylum. I found the video accidentially (thanks for YouTube) when I was searching information regarding how Onychophorans feed. People call them "water bears", and you will know why they are given such a cute name when you see how they walk. This animal is tiny, usually no bigger than a few mm, but they can be found in the most extreme environments on earth. Below are some introductory information on Tradigrada taken from Wikipedia: Tardigrades (commonly known as water bears) comprise the phylum Tardigrada. They are small, segmented animals , similar and probably related to the arthropods . Tardigrades were first described by Johann August Ephraim Goeze in 1773 (kleiner Wasserbär = little water bear). The name Tardigrada means "slow walker" and was given by Spallanzani in 1777 . The biggest adults may reach a body length of 1.5 mm , the smallest below 0.1 mm. Freshly hatched...
總算有機會坐下來反省,忽然覺得好似人越大越拘謹,就好像連簡單一聲對朋友的慰問都要諗一諗,又好像以往對不懂的東西立即發問那種即時反應性都在正在減退。這不是個好兆頭,整個人好像帶了無形的枷鎖。 ok,究竟是什麼原因做成的呢? 我不信是年紀問題。有可能是過勞。唔...其實我想有可能是被身邊那種保守、冷漠的氣氛感染了、同化了。還記得最初半年,我學校遇到熟人問好,每一次我都會停下來,希望可跟那人閒談幾句。但經過好幾次,正當我準備回應之前,那熟人已從身邊擦過。我才意會到「how are you?」or 「what’s up?」等一類問題,是不需要回應的。假若你認真的向別人介紹你的近況,人家會認為你很怪。後來我明白,80%的回應通常是: For "How are you?" The possible answers are: "Not Bad." "How are you?" "I'm fine, thank you!) 另一個我聽過數十遍的經典對白是"xx, what did you do for the weekend?" "nothing. how about you?" "nothing special..." 實在很討厭假裝友善,但毫不關心的問好。不想被同化,真是要多反省才行。
Five Year Old Cotton Picker by Lewis W. Hine, 1916 (LOC) 我們的社會很多時是進一步退兩步。 早一個月前大伙便已開始了五一勞動節的準備。五一日在加拿大並不是法定節日, 因此集會多是晚上六時舉行, 到遊行完結大多要到晚上八時。白天要上班的工人, 晚上還會精神抖擻地示威的為數不多。去年出席的人當中, 以那些中堅分子/組織者居多。 今年大會號召青年工人參與, 令我想起了我的朋友, 也今我想起了自己的處境。想到朝六晚十, 一邊讀書一邊工作, 回家倒頭便睡的生活。想到我們的精力是如此地給高昂的學費跟生活費榨乾, 我便感到無比的氣憤。看到好友滿面的頹容, 以及她滿眼的紅筋, 心又陣痛起來。希望我們能一同參加今年的五一。
