What is your education?

sorry it is Geography not geometry,tying error(I'm also regretful for my English)
obviously this is a geography problem...
I was graduate from Sichuan University,

What I'm not understand is for example it is 12'o clock at noon on summer soltice

the same place at the same time :i.e. 12' clock at noon, isn't it opposite to the sun on
winter soltice??? so it should be midnight???

I got dizzy with geography+3D geometry...

so does it means the peroid of earch rotation is 365*24/366 hours???

Are you scientist or something like this?

I saw here one chinese guy who solved the problems to sharpen his mind and now he is a researcher

No I'm not scientist,just solve hard problems for fun
