August 10th, you seemed so distant
Not quite as distant as the barrel of one gun
The gun that fired the shot that would stun
The scientific world, from Rutherford to Niels Bohr
To find out esteemed fellow scientist Moseley was no more

But before that, in 1913
X-ray spectra was naught more than a dream
Before diffraction through crystals became the truth
The wavelengths needed a meaning, and there was proof
You developed a mathematical system without flaw
One so great, it was named "Moseley's law"

Mendeleev had the right idea, but not a plan
Could not arrange the elements the way that you now can
Without you, my sir, we would not have had this premium
To enjoy the elements technetium, hafnium, promethium, and rhenium
These gaps that like stars littered the periodic table
Were filled with ease, and the cosmos became stable

You had set the foundation for crystallography of x-rays
A method of determining arrangement that is still used in modern days
The first machines in use were those for which you had the design
But their widespread use you could not see as there simply was no time
For during a battle, as you made the phone set run
A bullet took your grace away, a scientist dying young
