Science is not just a theory

Sciencebase - 15 November, 2014 - 10:53

I say theory, he says theory but what do you think we mean when we talk about theories, like Big Bang theory, the theory of evolution by natural selection, the theory of relativity (both general and special) and quantum theory. Well, we don’t mean it’s “just” a theory, like some vague idea a bloke down the pub came up with to explain the woes of the world, it’s not some conspiracy theory. If only we could’ve been more positive and used another word without the negative connotations of the man on the Clapham omnibus’ conception of the word theory…well, that’s the theory anyway.

Put them on hold

Sciencebase - 15 November, 2014 - 09:17

Songs of Experience by Dave Bradley

It’s a quarter of a century since the fall of the Berlin Wall, but still lives are put on hold by those who will divide and subjugate us. Isn’t it time, once again, to reject their calls, put them on hold?

Put them on hold

I made the call that I’m a free man
I talked wild of spirit, throughout the land
I saw the wonders that were open to mankind
I held up hope and love and life as gifts that we might shine

Then days became much darker than the night
The hope we had soon vanished from our sight
The love we took for granted we’d never find
Life fading fast as fear our hearts would bind

We put you on hold
Despite your objections
Despite your deflections
You will do as your told

When you’re out in the cold
No time for reflection
No more defection
We bring you into the fold

I dreamed that I could be a free man
I wondered if my spirit just might find a plan
I saw with wonder how despair crushed all mankind
No hope to hold, no love nor life to help us shine

We put you on hold
Despite your objections
Despite your deflections
You will do as your told

When you’re out in the cold
No time for reflection
No more defection
We’ll drag you into the fold

But, surely we can this hate denounce
We can this fear renounce
If there’s one ounce, one single ounce of decency left inside

We put them on hold
Despite their objections
Despite their deflections
We come in from the cold

We tear down the walls
At last, On reflection
from your hate we’re defecting
We reject all your calls
We reject all your calls

From my mini-album Songs of Experience
Words & Music by David Bradley
Vocals, instrumentation and mixing by DB
