It is zero kelvins or -273.15 degrees Celsius.

那时的温度是0开尔文，或者说-273.15摄氏度。

You wouldn't want to be getting your own hands too close to 4 kelvin.

你不想让自己的手离 4 开尔文太近。

This is a liquid helium tank, it's cold enough — it's at 4 kelvin, 4 degrees above absolute zero.

这是一个液氦罐，已经足够冷了——温度是 4 开尔文，比绝对零度高 4 度。

The energy units should match, so let's call the standard entropy 0.594 kilojoules per Kelvin.

能量单位应该匹配， 所以们称标准熵为 0. 594 千焦每开尔文。

So LHS 475 is an M-type star having a surface temperature of about  3300 kelvin.

所以LHS 475是一颗M型恒星，表面温度约为3300开尔文。

And so at 0 Kelvin the molecules are not moving.

因此，在0开尔文时，分子处于静止状态。

Good afternoon, my name is Kelvin Jones, I booked my internet yesterday.

下，的名字是 Kelvin Jones，昨天在网上预订的。

Daylight exists at roughly 5600 Kelvin, which leans quite blue.

光的色温大约是 5600 开尔文，偏向蓝色。

A sunset leans much warmer in the 3000 Kelvin range.

落的色温则更暖，大约在 3000 开尔文范围内。

Uh, did I seem a little… Zero Kelvin? Cold. - Yeah.

看起来是不是有点… … 过于无情、冷漠？ - 没错。

Phone screens at their baseline have a color temperature of 5600 Kelvin, or daylight.

手机屏幕的基本色温为 5600 开尔文，即光。

Which is exactly what Kelvin did — except with the earth, and scientific rigor.

这正是 Kelvin 使用的原——除了对地球，这种原有一定的科学严谨性。

Yet if we measure those atoms, they might be at temperatures up to a million kelvin.

但是如果们测量那些原子，它们的温度可能会在一百万k以上。

What's more, Kelvin was confident this idea would allow him to calculate the age of our potato...planet.

而且 Kelvin 相信这个想法能让他计算出地球的年龄。

Which is exactly what Kelvin did - except with the earth. And scientific rigor. He took

开尔文将这个论运用到了推算地球的年龄中。

It needed far more time than Lord Kelvin was willing to concede, and it was scarcely supported by fossil evidence.

一方面，要过很多年以后，它才最终得到开尔文勋爵的承认；另一方面，化石方面所提供的证据也少得可怜。

Kelvin Kemm, a South African nuclear physicist, said Africa needs to look beyond traditional sources, such as water and hydrocarbons.

Kelvin Kemm是南非核物学家，他说非洲需要寻找水和碳氢化合物等传统能源之外的能源。
