流星的出現，大部分原因是在太陽系運行的某些“渣滓“走近地球時被地球引力吸引而走進地球。在經過大氣層時產生摩擦而發光發熱，通常可分為兩類流星現象，偶發流星和流星雨。

那些獨個兒，沒有規則方向出現的流星，是因為流星體在太空中運行偶然和地球相遇所產生之現象，故又稱為偶發流星。另一類則是一大群地，沿著同一條軌道及同一方向環繞大陽運行的流星體。當它們和地球碰上時，便會相繼地進入地球大氣層。那如下雨般一樣壯觀的流星下落便稱為流星雨。

一般來說，如果有流星雨的話，我們每小時可見到大約五十顆流星。但有時每小時出現的流星數目達二三百顆我們稱為流星暴。

明年十一月的獅子座流星雨，相信每小時出現的流星數目會高達千多粒，甚為壯觀。而今年十一月的前奏，相信每小時亦有近千粒，這個流星雨的高峰將會在十一月十六和十七號，各位同學千萬別錯過！如果想得到更多關於該流星雨的資料，請密切留意天文學會的活動。

Most of them were taken with my Nikon FM10. The first moon photo was taken using the prime-focus method, and the second one used eyepiece projection.

PowerPoints

Physics was the one subject which I was addicted to when I was young – even until now I’d say it’s really amazing to learn about how the world works, although I realize better that it is really hard now.

My first trial in mobile programming. The classic Jewel game with the planets as “jewels”.

Supported Mobile Phones

This game should work on all Series 60 mobile phones with resolution 176×208, but currently only Nokia 6680 has been tested. Please let me know if you have tried it on other models and found that it works. Thank you.

Installation

Download both the JAR and JAD files, use the Application Installer of your Nokia’s PC Suite to install the application.

Not really useful, I did it solely for fun =)
