Re: Scientific American关于电子自旋的文章
Woit最新贴的Nature 虫洞论文Holographic wormhole也很有意思,cover story,炒作的杰作。他反弦理论数十年如一日,这次也不意外,估计学术界大佬全得罪完了,在物理学都混不下去了,只能在数学系当lecturer。

封面story上没看到Woit的名字啊。看到了Maria Spiropulu.Caravel 写了: ↑12月 1, 2022, 11:30 am Woit最新贴的Nature 虫洞论文Holographic wormhole也很有意思,cover story,炒作的杰作。他反弦理论数十年如一日,这次也不意外,估计学术界大佬全得罪完了,在物理学都混不下去了,只能在数学系当lecturer。

矩阵没头脑啊。。。他现在算体制外民科,只能写blog吐槽别人的封面文章,他自己怎么会上封面。
没有光子;也没有量子能级,量子跃迁,量子叠加,量子塌缩和量子纠缠。

量子计算和创造虫洞 Re: Scientific American关于电子自旋的文章
这个新闻值得单开一帖。John Baez 的评论也犀利:Caravel 写了: ↑12月 1, 2022, 11:30 am Woit最新贴的Nature 虫洞论文Holographic wormhole也很有意思,cover story,炒作的杰作。他反弦理论数十年如一日,这次也不意外,估计学术界大佬全得罪完了,在物理学都混不下去了,只能在数学系当lecturer。

Unfortunately Natalie Wolchover didn’t seem to realize that this hype was merely hype: on Twitter she wrote: “Curious to see so many people approve of the article but bristle at the headline. Can someone (who has actually read our article or the Nature paper) articulate *why* they don’t think it’s valid to say the experiment created a wormhole?”
Various people who know what’s going on tried to explain it carefully and gently. But I think one has to be brutally clear in situations like this, so I replied:
They did an simulation that crudely, roughly mimicked a system dual to a 2d wormhole. So it’s like a kid scrawls a picture of an inside-out building and the headline blares
BREAKING NEWS: CHILD BUILDS TAJ MAHAL!
