  It's like feeling.
  就像去触摸
• 
  
  So what you have here is a glass fiber
  你有一根光纤
• 
  
  that's drawn down to a very sharp point and coated with aluminum,
  有一个很尖的镀铝的端头
• 
  
  and the hole at the bottom is just 100 nanometers;
  而底下的洞只有一百纳米那么大
• 
  
  that's like 100 molecules,
  差不多一百个分子的宽度
• 
  
  not really, really tiny like the scanning tunneling microscope.
  没有像隧道扫描电镜那么小
• 
  
  So what you do is you have something
  而你要做的是把要观察的
• 
  
  on the surface of a slide here that you want to probe with this,
  什么东西放到一张底片的表面上
• 
  
  and you send light down the thing,
  然后对它送光
• 
  
  and if there is a molecule where the light's coming out,
  而如果那里有个原子的话
• 
  
  through this tiny hole, if there's a molecule there,
  从那个洞出来的光
• 
  
  that will take the blue light and emit red light.
  就会因原子的存在从蓝色变成红色
