When I drove to work yesterday, I met a traffic jam（交通阻塞）. As I looked out of my window, a young man was walking on the street. He was walking to the bridge. There were some homeless men with their cups around there. The young man went to one of them. He brought out some money, said a few words to him and put the money into his cup. He continued（继续） to walk and then saw another homeless man. He stopped for a minute, said a few words and then gave the man a candy.

And then he saw the next homeless man. He was shivering（冷得发抖） because of coldness. The young man now stopped and gave his scarf to him. He then said goodbye to him with a big smile and went away in the snow.

At that moment, I was in tears（流泪）. I gave this young man my best wishes with love and blessings.

1609年8月21日，意大利科学家伽利略展示出了人类历史上第一架按照科学原理制造出来的望远镜．其实最早发现望远镜的人不是伽利略，而是一位叫利波塞的荷兰眼镜商人，这个人在制造镜片的时候，把一块凸透镜和一块凹透镜合在一起往外看，远处的东西就变近了．伽利略对这个发现很感兴趣，他用数学进行了计算，研究用什么样的镜片，怎样组合在一起效果最好，最后，伽利略做了两根管子，一根管子的一端放凸透镜，另一根管子的一端放凹透镜，其中一根稍细一点，正好可以套在另一根管子里面，自由滑动，这样观察的时候，就可以来回调节，选择合适的距离．就这样经过反复的研究和实验，他终于在1609年发明了世界上第一架能放大32倍的望远镜．

（1）最早发现望远镜奥秘的人是利波塞，而人类历史上最早按照科学原理制造出望远镜的人却是伽利略，这里说明了什么问题？

（2）伽利略制造出来的望远镜与教材上所画的天文望远镜有什么不同？
