在屋顶装个锅,Satellite TV能从几万公里高空的同步卫星那里接收电视信号,我能理
解;甚至能够接收互联网数据信号,我也能理解。可是当我在浏览器里输入一个网址,
回车,这个网址请求岂不是要通过屋顶的锅发送到几万公里高空处,同步卫星才能接收
到,并发给地面工作站处理?屋顶这个锅的能力这么强么?

海归某高校,细胞生物学领域,如果有100万人民币的启动资金,你会先买一些简单的
仪器和耗材,做一些简单的实验,然后尝试发一些简单的小paper;还是会准备买一些
贵的东西,做一些有难度的实验,然后aiming档次高一些的journal?

不可能发给卫星, 卫星上网很贵的,

It depends and the answer varies depending on what you have in your hand.
No one starts a lab from scratch. you always have accumulated something to
ensure a good start during your previous stage (e.g., postdoc) and at least
several publications within the first year.

Thanks for your input. I already had some ideas, extending my previous work.
But the experiments would consume a lot of money, and I am a green hand
running my own lab. Just wanna hear some useful tips from you smart and
seasoned guys :)

这个真的看你做什么方向
有些方向重点根本不在实验室建设上
有些则基本就要靠有基本的实验室设备

这个很稀奇么?美国加油站的收费系统基本都是卫星的,不要说那么复杂的锅了,就是
没锅的,UHF手持电台,用Yagi天线都能跟国际空间站通信,那玩意才5W功率。摩托罗
拉的铱星手台用相控阵天线,功率还不到5W.
卫星通信没你想的那么复杂,当然,directTV有没有卫星上行那是另外一会事。
