Dan's energy and spirit... he was like a comet... he TOOK OFF — but the sparks from that comet continue to set fires in people and I think will continue to do so for a very long time.

丹的能量和精神，他就像一颗彗星，匆匆离去，但是他一闪而过的光芒仍然留存在人们心中，而我相信，还能留存得更久。

Furthermore, memory can also be shut on and off as required to help balance server workloads, which have the effect of further decreasing energy consumption.

另外，还可以根据需要打开和关闭内存，这有助于平衡服务器工作负载，进一步降低能源消耗。

They already buy into the concept if reducing energy consumption and switching things off - even if, in practice, they aren't very good at it.

他们本来就接受减少能源消耗和关闭电器开关这些观念——即使他们在行动上并不是无可指摘。

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。

But the slow decay in radiation intensity from a tabletop pulsar would make possible extremely long-range transmitters, giving far-off space probes an energy-efficient way to beam information back to earth.

ECONOMIST: Physics

Pylons are a necessary evil if we are to wean ourselves off carbon-based energy.

BBC: Landscape impact of electric pylon softened by design?

We believe people everywhere would see their economies crippled by a cut-off in energy supplies.
