Introducing myself...Philippe from China

Good morning,
My name is Philippe, I'm now reached 70 years old and presently retired in China.
For my pleasure to learn and make my brain working, I started to read and learn about Quantum mechanics. Its starting by Blackbodies and the Rayleigh-Jeans law.
As with age I forget even how to make a partial derivative, I will have trivial question related to physics and mathematics.
Please, be patient with me.

As well as I'm new on this forum (first time in such a forum), I don't know exactly how its works.

Please, note as well that here in China: google, twitter, facebook, yahoo even now Wikipedia are blocked by the authorities so my way to learn is limited

Tanks in advance and best regards

Philippe

@philippe:
Quantum? I heard one bad guy in China (in guokr.com) said that no physist in the world truely understand QM. When I tried to learn Quantum myself, I took a glimpse at the blackbody issues and jump over, go ahead...
"Please, note as well that here in China: google, twitter, facebook, yahoo even now Wikipedia are blocked by the authorities so my way to learn is limited"...??? It's not the authorities do that? It should be business affair?

No no Neila all the websites I mention are blocked by the authorities who are using the "great wall firewall' it's not due to a business affair...

@philippe:
I often wrote the message in Microword and then copy it here. Some odd symbols and Greek letters can be found in Microword. The pin over the window is for attachment. I used to attach file too, but I found it not working recently.
I don't know how to use Letax in this forum either. You may ask the forum admin Topsquark in this respect. He is also called Dan. But I like to call him "that dragon"...He is American, but it's strange that he call himself dragon. haha...

We have a LaTeX compiler. It's fairly simple to learn and you can "quote" a post that has LaTeX in it to learn how they wrote it. (The boldface LaTeX is a link to our LaTeX help forum.)

For example, "quote" this post.
$\displaystyle x^2 + 3x - 5 = 12$

It's a personal thing. And no, I'm not going to share!

I had heard about the "great fire wall", but was unsure what it covered.
Its a shame that Wikipedia is blocked,
I can see why it would be, but some of the physics pages are really quite good,
and we tend to use links to them quite frequently.
I will try to remember that you and Neila don't have access,
and actually copy the salient facts into my posts rather than link to these sites.

Dear All,
Thanks for your reply.
A solution to bypass this great fire wall is to have a VPN.
I had one but unfortunately this one has has been deactivated by the cyber authorities.
Thanks for all your reply
Good night
Philippe
