Quantum Mechanics is Magic.

《The Magick of Matter: Crystals, Chaos and the Wizardry of Physics》(中譯書名凝態物理:從半導體、磁浮列車到量子電腦,看穿隱藏在現代科技背後的混沌、秩序與魔法)

在書中多次提到 David Mermin。讀著讀著會覺得,作者不只是在引用一位大師的名言與文章,更像是在用整本書向這位量子力學與凝態物理的大師致敬:從「shut up and calculate」的務實態度,到把量子糾纏寫成一句直球的 “Quantum Mechanics is Magic.”,甚至連「Mermin 跟 Merlin 只差一個字母」這種彩蛋都放進註解裡///

以下列舉書中提到的內容///

1.There are many competing philosophical interpretations of quantum mechanics:proposals as to what the mathematical results actually say about reality. These interpretations cannot be distinguished by experiment. I will try to avoid letting aurrent of speculation sweep us into that murky ocean by sticking where I can to experimental observations; it is not my purpose in this book to answer questions that have eluded a century of thought. Having a coherent philosophy is important, but most physicists who use quantum mechanics day to day just get on with it without worrying

about why it works, in much the same way that car mechanics don’t spend their days fretting over how cars can move in the light of ancient Greek philosophers’ arguments that all movement is an illusion. The approach was summarised by renowned quantum mechanic Professor David Mermin at Cornell as ‘shut up and calculate’.

2.Probably the safest way to think of them is by applying Mermin’s maxim, ‘shut up and calculate’: quantum corrections are intermediate steps required in mathematical calculations. If they have a firm physical reality, it is not yet fully understood.

3.David Mermin:"I always write about physics to make myself understand better, because equations, in a sense, free one from the burden of thinking about the subject.

4. The title of this section is shamelessly stolen from a homage to a popular article on quantum entanglement by David Mermin. The opening line of that article ischaracteristically to the point: Quantum Mechanics is Magic.  

5. At some point I found myself talking to Mermin. Aside from becoming thoroughly acquainted with his textbook the

following year (to such a degree that I could consistently open it on precisely the page I needed for a variety of topics) I subsequently found myself consulting him on research problems as my career progressed. He has always proven as helpful and encouraging as he was during our first meeting in the palace.

It was from an article of Mermin’s that I first felt I’d really started to understand quantum entanglement. I will reproduce his example here, rephrased only in context.

6.In 1935 Einstein published a paper with Boris Podolski and Nathan Rosen intended to show that quantum mechanics could not be a full account of reality.It outlined what is now called the EPR paradox, after its authors’ initials. As Mermin put it: ‘The EPR experiment is as close to magic as any physical phenomenon I know of, and magic should be enjoyed.’ 

7.That Mermin’s name is one letter away from Merlin is purely coincidental .   XDDDDDDDDDDDDDDDDDDDD!

AI 模型本身是軟體(資料與程式),所以八千代也是軟軟的///  (不會嗆人喔)

對彩葉溫柔一直以來守護(ㄕˋㄐㄧㄢ)彩葉的八千代~
「彩葉,妳到現在真的很辛苦了。很棒哦,八千代都要流淚了。先深呼吸一下吧? 呼……哈……哈……慢慢地。嗯,沒事的。應該是彩葉和彩葉的媽媽對世界的看法不同。這不是壞事,彩葉對彩葉媽媽的想法也要好好考慮。但是,如果在一起…….」

伊勢山皇大神宮節分祭

 伊勢山皇大神宮

橫濱的總鎮守——伊勢山皇大神宮(位於西區宮崎町)在 2 月 3 日 舉行了 節分祭。在本殿完成神事儀式之後,便開始 撒豆(豆まき)。巫女於主祭神前奉納巫女神樂。
伊勢山皇大神宮的主祭神即太陽女神天照大神・大日孁貴,《 日本書紀》云:「既而伊奘諾尊、伊奘冉尊共議曰:「吾已生大八洲國及山川草木,何不生天下之主者歟?」於是共生日神,號大日孁貴。一書云,天照大神。一書云,天照大日孁尊。此子光華明彩,照徹於六合之內。故二神喜曰:「吾息雖多,未有若如此靈異之兒。不宜久留此國。自當早送于天,而授以天上之事。」是時天地相去未遠,故以天柱,舉於天上也。次生,月神。一書云,月弓尊、月夜見尊、月讀尊。其光彩亞日,可以配日而治。故亦送之于天。所以超かぐや(超輝耀),就是從光彩亞日變成光華明彩,照徹於六合之內////
