《那些古怪又讓人憂心的問題》第56期:尤達大師(1)
YODA
Q. How much Force power can Yoda output?
Q．尤達大師的原力的輸出功率有多大？A. I'M GOING TO-of course-ignore the prequels.
A．星戰前傳不在本文的討論範圍之內，你們懂的。
Yoda's greatest display of raw power in the original trilogy came when he lifted Luke's X-wing from the swamp. As far as physically moving objects around goes, this was easily the biggest expenditure of energy through the Force we saw from anyone in the trilogy.
在《星球大戰》原三部曲中，最能夠展現尤達大師原力風采的當數他把盧克的X翼戰機從沼澤裏提出來了。就物理移動物體這一點而言，尤達此舉無疑是整個三部曲中消耗能量最多的一次。The energy it takes to lift an object to a given height is equal to the object's mass times the force of gravity times the height it's lifted. The X-wing scene lets us use this to put a lower limit on Yoda's peak power output.
提升一個物體至一定高度所需的能量等於物體的質量乘以重力加速度乘以提升的高度。從尤達提起X翼戰機一事中，我們可以猜出尤達最大輸出能力的下限。First we need to know how heavy the ship was. The X-wing's mass has never been canonically established, but its length has-12.5 meters. An F-22 is 19 meters long and weighs 19,700 kg, so scaling down from this gives an estimate for the X-wing of about 12,000 pounds (5 metric tons).
首先我們要知道一架戰機有多重。X翼戰機的重量從來沒有官方的說法，但我們知道它的長度爲12.5米。一架F-22戰機長度爲19米，質量19700千克，所以按比例算下來X翼戰機的重量大約爲5600千克。Next, we need to know how fast it was rising. I went over footage of the scene and timed the X-wing's rate of ascent as it was emerging from the water.
接下來我們要知道提升的速度有多快。我又去看了一遍電影中這個場景，給X翼戰機提出水面的場景記了個時。The front landing strut rises out of the water in about three and a half seconds, and I estimated the strut to be 1.4 meters long (based on a scene in A New Hope where a crew member squeezes past it), which tells us the X-wing was rising at 0.39 m/s.
戰機的前起落架用了約3.5秒才從水中出來，我估算了一下起落架的長度大約爲1.4米（基於《星球大戰4：新希望》中一名機組成員從起落架前擠過的場景計算），因而X翼戰機的提升速度爲每秒0.39米。Lastly, we need to know the strength of gravity on Dagobah. Here, I figure I'm stuck, because while sci-fi fans are obsessive, it's not like there's gonna be a catalog of minor geophysical characteristics for every planet visited in Star Wars. Right?
最後我們要知道達戈巴星球上的重力加速度。我目測自己要卡在這個問題上了，因爲就算科幻迷們再狂熱，也不太會有《星球大戰》中去過的每顆星球的地質特性的目錄表，對吧？Nope. I've underestimated the fandom. Wookieepeedia has just such a catalog, and informs us that the surface gravity on Dagobah is 0.9g. Combining this with the X-wing mass and lift rate gives us our peak power output:
不，我低估了影迷們的能力。烏奇百科上就有這麼個目錄表，從上面我們可以得知達戈巴的表面重力加速度爲0.9倍地球重力加速度。算上之前得到的X翼戰機的質量和提升的速度，我們可以計算出峯值輸出：
