从小到大都知道，学习语文是需要有写作能力的，学习数学的时候，也需要写作能力吗？是不是跟写作能力有关？ 第1页

我觉得只要是理论科学都挺需要表达能力的，因为在讨论的时候很容易产生鸡同鸭讲的问题，原因有可能是1.关键概念没有明确定义，比如4题中intensity就有很多歧义[1]。2.语言表达能力有严重缺陷，导致对方需要猜测表达者的意思，从而引起更进一步的歧义，3题这句子读几分钟越读越不对劲。

[1] Several measures of light are commonly known as intensity:

• Radiant intensity, a radiometric quantity measured in watts per steradian (W/sr)
• Luminous intensity, a photometric quantity measured in lumens per steradian (lm/sr), or candela (cd)
• Irradiance, a radiometric quantity, measured in watts per meter squared (W/m2)
• Intensity (physics), the name for irradiance used in other branches of physics (W/m2)
• Radiance, commonly called "intensity" in astronomy and astrophysics (W·sr−1·m−2)

结果想要表达的意思是E=number of Photon*h*v (eV)
