Mindfulness or Mindlessness?

[DLJ]

...
Now, light with a wavelength of 680-700 nanometers does exist.
...

The people's flag is deepest light with a wavelength of 680-700 nanometers,
It shrouded oft our martyred dead,
And ere their limbs grew stiff and cold,
Their hearts' blood dyed its ev'ry fold.

Then raise the light with a wavelength of 680-700 nanometers standard high.
Within its shade we'll live and die,
Though cowards flinch and traitors sneer,
We'll keep the light with a wavelength of 680-700 nanometers flag flying here.

It loses something in translation.
Conclusion, physicists shouldn't write poetry.
