The Man Who Weighed the Earth in Silence (Henry Cavendish)

Lyrics

[Verse 1]
You were the richest man in England
and you owned one suit
which you wore until it could no longer
be called a suit
and then you wore it further
You ate the same meal every night —
a leg of mutton,
ordered by note left on the stairs
because speaking to the servants
required a kind of social processing
the amygdala would not permit
If a maid encountered you in the hallway
you fired her —
not from cruelty
but from the specific terror
of being perceived by someone
whose perceiving
you had not scheduled

[Verse 2]
The anterior cingulate
monitors conflict between intention and environment
and yours must have been deafening —
every room with a person in it
was a room that needed leaving
every dinner invitation
was a corridor you could see the end of
and the end always contained
someone asking you a question
with their face
You went to the Royal Society meetings
and stood in the corner
and if someone approached you directly
you made a sound
that witnesses described
as something between a squeak
and the word leaving
and then you left

[Chorus]
But alone — alone in the laboratory
on Clapham Common —
you were the steadiest hand in Europe
You discovered hydrogen
by pouring acid on zinc
and collecting what rose
You calculated the density of the Earth
using a torsion balance so sensitive
it could measure the gravitational attraction
between two lead spheres
in a sealed room
that you observed through a telescope
from the next room
because even the air displaced
by your own body
would have ruined the measurement
The Earth weighs what it weighs
because you were willing
to leave the room it was in

[Verse 3]
You discovered the composition of water
and told almost nobody
You anticipated Ohm's law by a century
and published nothing
You found the specific heat of gases
and filed it in a notebook
that nobody read until Maxwell
opened it sixty years later
and found a career's worth of physics
sitting in a dead man's handwriting
as if the results
had been waiting in a queue
that only silence could operate

[Bridge]
They tried to honor you at dinner parties —
scientists who admired your work
would approach and speak of your discoveries
and you would shrink
into a shape the room
could barely accommodate:
shoulders drawn, gaze fixed
on a point six inches below
the other person's chin,
the somatosensory cortex
registering every approaching hand
as a detonation in progress
You were not shy —
shy is a word for people
who want to be in the room
but cannot manage it
You did not want to be in the room
You wanted to be in the room
next to the room
watching through a telescope
which is where you did
your best work

[Outro]
You died at seventy-eight
in the house on Clapham Common
having spoken perhaps
fewer words in your lifetime
than most people speak in a year
The notebooks Maxwell opened
contained enough unpublished physics
to have made you the most famous
scientist of your century
if you had been willing
to hand them to another human being
but handing things to human beings
was the one experiment
you could never design a protocol for
The drawer where they keep your work
was sealed shut by the same hand
that filled it —
you were the lock
and you were the key
and you could not bear
to be both at once
in front of anyone
