弦理论(string theory),即弦论,是理论物理学上的一门学说.弦论的一个基本观点就是,自然界的基本单元不是电子、光子、中微子和夸克之类的粒子.这些看起来像粒子的东西实际上都是很小很小的弦的闭合圈(称为闭合弦或闭弦),闭弦的不同振动和运动就产生出各种不同的基本粒子.弦论是现在最有希望将自然界的基本粒子...
You could imagine someone proving that the various perturbative approaches to String Theory become inconsistent when stitched together into a full non-perturbative theory. Alternatively, you could imagine someone proving that a theory like String Theory is unique, that no other theory can do some key...
StringTheory弦理论 虽然弦理论最开始是要解出强相互作用力的作用模式但是后来的研究则发现了所有的最基本粒子包含正反夸克正反电子正反中微子等等以及四种基本作用力粒子强弱作用力粒子电磁力粒子以及重力粒子都是由一小段的不停抖动的能量弦线所构成而各种粒子彼此之间的差异只是这弦线抖动的方式和形状的不同而已 String...

you pretty much have to be a multidisciplinary mathematician able to handle with easy branches from differential and algebraic topology, differential and algebraic geometry, complex analysis and even number theory; this besides the amount of physics needed, since ordinary quantum field theory per se is...
Recording A String Section: Theory & Practice Recording a very large string section is a task that is beyond the scope of the current article. Thankfully, though, this subject was covered in depth by Hugh Robjohns, back inSOSMay 2006. As well as taking you through mic techniques, this ar...

The Keto flour and the Swerve granulated, brown and confectioners sugars all claim to be near analogs in baking – in theory they can be subbed one-to-one for conventional products. In practical use, not really. More like “kinda” and “maybe.” To start with I find the Swerve products...

Then why parseFloat(null) should return a NaN here? Someone please explain this design concept to me. undefined ❌ ❌ ❌ As expected. Infinity ✔️ ✔️ ❌ As explained before, isNaN() considers infinity as a number, and parseFloat() parses infinity as infinity. So...which ...
