Two years ago, Tammet became famous for reciting pi to 22, 514 decimal places with the same ease that the rest of us can reel off 3.142.

两年前，Tammet因为背诵 π 至小数点后22514位而出名，而且他背起来就像我们背到3.142那么容易。

So z equals 7 -- this is the cut-off where, in fact, the sigma orbital is going to be higher in energy than the pi 2 p orbitals.

所以z等于7-这是分界点，实际上，sigma轨道能量,要比π2p轨道高。

z And what you need to remember is if the z 8 is equal to eight or greater, such as oxygen being the cut-off point, this sigma 2 p orbital is actually lower in energy than the pi 2 p orbitals, the molecular orbitals.

你们要记住如果,等于或者大于，就像O是分界点，这时sigma2p轨道,比π2p轨道能量更低。
