大家有無咩關於physics嘅問題但又無地方問

唔識反彈嘅果然翁 2021-6-29 19:48:01 佢話唔會快過光
光既speed 係同一個medium 係constant 黎

:^(

ie c(apparent)=c
佢describe既係 c(apparent) < c

逃避型依戀 2021-6-29 19:53:06 如果prove到牛頓定律係錯成個physics係咪就會推翻晒？

唔識反彈嘅果然翁 2021-6-29 19:53:14 完全唔識

信長之北野望 2021-6-29 19:53:41 你條片入面嗰個只係普通光學double slits實驗，唔係QM嗰個double slit，你再上條片嗰個就係用電子去做。至於儀器，你可以睇下面條片，佢用detector加喇叭做例子，解釋得幾好。

wave function collapse其實上面個實驗都Show到。「可以用儀器影響去解釋」唔代表一定係儀器影響咗佢。
Copenhagen interpretation只係其中一個interpretation，仲有其他interpretation例如多世界詮釋。你覺得儀器影響咗結果，但係我可以話佢分裂咗做平行宇宙，一樣解得通，但係Copenhagen應該係最主流，除咗"I dont know"之外

唔識反彈嘅果然翁 2021-6-29 19:55:48 唔係變左useless energy 咩

:^(

除非universe 之外有energy loss 姐
唔係既話唔係closed system 黎架咩

:^(

唔識反彈嘅果然翁 2021-6-29 19:59:15 吓點推翻
佢都係鳩up 話有一舊野叫mass 既東東
而你想move 佢就要apply force
acceleration就係你除出黎既product

唔識反彈嘅果然翁 2021-6-29 20:04:40 因為 Potential Difference (voltage) = Current x Resistance
佢企係條電纜上面
但係佢無Connect 去一個低potential 既 object(例如地下)
咁個current 就會係0
電死人係電流

呀邊個 2021-6-29 20:04:59 點睇M理論? 會唔會做到大統一理論?

信長之北野望 2021-6-29 20:05:41 咁你當佢已經被推翻咗啦

:^(

newtonian mechanics只可以準確描述較慢（eg.車、飛機、麥巴比）同較大（eg.人、黃豆）嘅嘢
快到接近光速要用相對論、細到電子咁就要用QM

好似唔係

唔識反彈嘅果然翁 2021-6-29 20:09:42 因為atmospheric 既conductivity?

:^(

佢個potential 夠高就會有arching 電瓜你?

想起他蕉都興奮 2021-6-29 20:10:56 fusion係

fission唔再係講binding force
佢嘅energy release係嚟自唔見咗嘅mass
