理解力
伽利略 最有名的實驗為比薩斜塔的自由落體實驗
他證實了 物體的落下速度與重量無關
他確立的實驗在科學知識中的必要性
然而
若假定 重量較大速度較快
我們可以發現若兩個物體 一重一輕
則以假定之推論 應該是 兩者落下的速度為
輕者慢 重者快
若將個物體結合 我們可以想像
速度應該是要平均 而變慢才是呀
可是兩者和一之後重量變重 應該要突然變快
得到矛盾的結果 可得假定為錯誤的
因此物體落下速度 與重量 無關
我們並不需要實驗就可以得到真實的結果
那什麼是理解力？
網路筆記 File Upload on PHP Server in Android
http://sunil-android.blogspot.tw/2013/09/file-upload-on-php-server-in-android.html http://www.webtech.tw/info.php?tid=24 For this using multipart boundary. So here question is arises what is multipart boundary and why use it? The Content-Type field for multipart entities requires one parameter, "boundary", which is used to specify the encapsulation boundary. The encapsulation boundary is defined as a line consisting entirely of two hyphen characters ("-", decimal code 45) followed by the boundary parameter value from the Content-Type header field. Thus, a typical multipart Content-Type header field might look like this: Content-Type: multipart/mixed; boundary=gc0p4Jq0M2Yt08jU534c0p This indicates that the entity consists of several parts, each itself with a structure that is syntactically identical to an RFC 822 message, except that the header area might be completely empty, and that the parts are each preceded by the line --gc0p4Jq0M2Yt08jU534c0p. Things to Note...
