I finally got one over

The other day, Louise and I got into some petty argument. (I say it was petty. She would have said it was Armageddon.) As is our nature, neither of us would admit the possibility that we might be in error.
To her credit, Louise finally said, 'Look. I'll tell you what. I'll admit I'm wrong if you admit I was right.'
'Fine.' I said.
She took a deep breath, looked me in the eye and said, 'I'm wrong.'
I grinned and replied, 'You're right.'

Davy's safety lamp

In 1815, English chemist, Sir Humphry Davy of London patented the miner's safety lamp. Miners at work constantly met firedamp, an explosive mix of methane gas and air, during the working of coal. This was an almost insurmountable obstacle to the working of many of the collieries until the discovery of the safety lamp. The flame of the safety lamp is surrounded by a copper or iron gauze cylinder, with openings no more than 1/24-inch. Such a fine gauze prevents flame passing through, but fails if coarser. The wire absorbs or conducts away the heat of the flame contained inside the lamp so it does not explode gas outside the lamp. If firedamp is present, a pale blue flame appears around the central flame. This warns a miner to leave the area immediately!
