一个空的电子阅读器和一个满的电子阅读器相比,差距仅有十的负十八次方克。
The difference between an empty e-reader and a full one is just one attogram.
如果你们不在这77%中,让我们快速的来看一看为什么,这个是正确答案,0,9乘以10的负18次方焦耳。
So if you're not in this 77%, let's quickly go over why, in fact, this is the correct answer,. 9 times 10 to the negative 18 joules.
如果我们已知电子以,10的5次方每秒的速度运动,那么做一个计算,可以得知它的波长是,7乘以10的负9次方米。
So, if we do this calculation for an electron, saying it moves at 10 to the 5 meters per second, then what we end up with for a wavelength is 7 times 10 to the -9 meters.
所以1,1乘以10的负31次方米,事实上并不是一个很重要的数字,举例来说,当它与一个球的长度,或者一块棒球场地对比时。
So 1.1 times 10 to the -31 meters is not, in fact, a significant number when we're comparing it, for example, to the length of a ball, or the size of the baseball field.
所以如果我们稍微想想,我们需要的数值是多少,我们需要一个,大约为10的负30次方米每秒的速度。
So, if we kind of think about the Numbers we would need, we would actually need a velocity that approached something that's about 10 to the negative 30 meters per second.
根据加州大学伯克利分校的教授约翰·库比亚托维兹所说,下载满容的电子书阅览器与空的阅览器相比,差距仅有1微微微克,也就是10-18 克(十的负十八次方克)。
According to John Kubiatowicz, from the University of California, Berkeley, the difference between an empty e-reader and a full one is just one attogram, or 10-18 of a gram.
对单个原子,就是10的负18次方焦耳。
1埃的立方等于10的负30次方。
那么当然这是一加上三倍的e的,负相互作用E比kT次方。
So of course this is one plus three e to the minus E int over kT.
一些理论物理学家认为宇宙的量子本质应该在“普朗克常数”范围内:即十的负三十五次方米,而一毫米才不过十的负三次方米。
Some theories suggest that the quantum nature of space should manifest itself at the ‘Planck scale’: the minuscule 10-35 of a metre, where a millimetre is 10-3 m.
它等于T分之一,单位是秒的负一次方,大部分物理学家叫它赫兹
It is one over T, and so the units are seconds minus one but most physicists would call that "hertz."
4乘以10的负19次方。
然后C有一个很小的二次方的上升,接着指数的上升直到你预期的饱和,那C约等于A0乘以1减,的负k2乘以时间次方,e,to,the,minus,k2,times,time。,速率常数k2长时间地起主导作用。
And then C has a very small quadratic rise, followed by the exponential rise to saturation that you'd expect. So C is approximately a0 times one minus e The rate constant k2 dominates the long times.
v倍的t等于V0倍的e的负cs乘t次方。
Vee times tee equals Vee sub zero times ee exponent negative Cee sub five tee.
佛陀“最初原子”等于是四厘米除以七的十次方,也就是0.04米乘以7的负10次方或者0.00000000001416米,差不多就是一个碳原子的大小。
The Buddha's "first atoms" are, therefore, 4 centimeters divided by 7 ten times, which is 0.04 meter x 7 to the minus 10 or 0.00000000001416 meter, which is more or less the size of a carbon atom.
那么横截面就等于,8乘以10的,负五次方平方米。
That would give me a cross-sectional area of eight times ten to the minus five square meters.
面积是2乘以10的,负七次方,除以面积。
The area is two times ten to the minus seven, and I divide by the area.
数学课上认真听讲的读者朋友或许都能想起二次方程序通常有两个解:一个是正解,另一个是负解。
READERS who were paying attention in their maths classes may recall that quadratic equations often have two solutions, one positive and one negative.
负面植入物是电浆型态的黑洞。每个黑洞的直径约为一个电子的大小(10的负17次方公尺)。
An implant is a plasma black hole with an approximate diameter similar to the diameter of an electron (10-17 meters).
负面植入物是电浆型态的黑洞。每个黑洞的直径约为一个电子的大小(10的负17次方公尺)。
An implant is a plasma black hole with an approximate diameter similar to the diameter of an electron (10-17 meters).
