Hello Everyone! I am (half) a physicist. 大家好，我是（半個）物理人

Hello everybody on Steemit! I am John from Hong Kong. I did Physics and Mathematics at University and have recently graduated. That's one of the two reasons I said I am only half a physicist. The other reason was because I know far too little about Physics to call myself a physicist: Physics is a very deep and broad subject that asks the most profound questions about our Universe. Nowadays, physicists have to spend years just to be good at a very narrow topic. I am certainly not as professional as them! But I do have a geniune passion to learn about our beautiful Universe.

Steemit上的大家好！我是個剛剛從大學畢業的香港人。大學時我修讀數學和物理，所以嚴格來說我只是半個物理人。我也不敢說自己是個物理學家，只因物理實在太博大精深了。今時今日，物理學家光是要在物理裏面的一個細小的範籌成為專家，已經要花上以十年為單位的時間了。我實在不敢以物理學家來稱呼自己。可是我可以不臉紅的說自己是一個物理人：我真的對理解這個宇宙的奧秘非常的有熱情。

According to the arXiv, apparently these are the topics there are in Physics:
根據arXiv的分類，好像物理還有挺不少分支的，支支都不簡單的啊:

Let me tell you why I joined the Steemit community. First of all, I really enjoyed reading some of the articles on Steemit when I was introduced to it by a good friend. It seems everyone is very friendly here as well! The vast number of articles on Steemit covered many topics, but as half a physicist I immediately noticed one thing: where are the posts related to Physics? That was what motivated me to create an account: I want to try to bring this interesting subject to more interested people!

等我講一下為什麼我加入了Steemit吧。當我的好朋友介紹Steemit給我，我發覺在Steemit上有很多很有意思的文章，這裹的人也給我非常友善的感覺。可是作為半個物理人，我馬上發覺一件事：跟物理有關的熱門文章似乎有點少？我決定申請一個帳戶，希望可以在這裹把這個（至少我覺得）很有意思的科學帶給大家。

What kind of Physics will I be talking about then? Perhaps you can give me some ideas! (Then I will try my best...) Actually what comes to your mind when you think of Physics?

物理學裏有那麼多的分支，那我會想寫什麼樣的物理呢？或許你可以給我一點靈感？（然後我試試去寫吧。。哈哈）。話說物理讓你聯想到什麼東西呢？

Newton hit by a falling apple?

無辜的牛頓？

Einstein's ridiculous hair?

愛因斯坦的髮型？

Some science on a blackboard?

黑板上的方程式？

(from https://www.timeshighereducation.com/student/subjects/what-can-you-do-physics-degree but by the way, half of what's on that blackboard is not Physics. 不過其實這塊黑板上有一半不是物理。。。)

I am sure many of you thought of this!

應該有不少人聯想到這道有名的方程吧！

(from pexel, or Einstein himself!)

We are getting close to the kind of Physics that I did at uni. What I did was actually more like
我們離我在大家讀的物理愈來愈近了。其實我在大學讀的比較像下圖

Please don't be scared! As Einstein said (or is credited for saying):

"If you can't explain it to a six year old, you don't understand it yourself."

I am not Einstein (He's my favourite physicist, by the way), but I am guessing you aren't six years old either :) Maybe it will work out. Who knows. Maybe next time!

請不要立馬走人！聽說愛因斯坦說過這樣的一句話：

"如果你不能跟一個六歲的小孩子講明白，你自己也沒有很懂。"

我不是愛因斯坦（他是我偶像！），但幸好你也不止六歲 :) 或許能行？ 或者下次吧！

If you have read all the way down to here, thank you very much! I look forward to hearing from you all. Nice to meet you again everybody!

如果你有耐性看到這裏，我真的很感謝你們！希望你們能留個言，大家交個朋友。多多指教！
