The dangers of finding long lost parents... [Jun. 23rd, 2009|06:05 am]

William Ireland, 50, of Atherstone, claims he was six when dad Ken left his mum to start a new life, reports The Sun.

He later tracked him down and admitted: "I spent a lot of childhood pining for dad.

"When I found him we started seeing each other then he died in 2006. I found out his estate was going to the woman he left my mother for and their son.

"I thought he might have made it up to me. Obviously he never cared."

Mr Ireland got the ashes after paying for the funeral. His father's second wife and family are thought to want them back.

The eBay ad reads: "Here are the ashes of my father, Kenneth Ireland, an adulterer who left a wife, two children and just £17 in her pocket. He never paid a penny towards his kids' upbringing."

Haidinger's Brush, or "How to see polarization with the naked eye." [Jun. 23rd, 2009|07:00 pm]
You can see more than just colours with your limited human vision!

"I can see it particularly clearly in the twilight when I stare at the zenith; the whole sky seems to be covered by a network, as it were, and everywhere I look I see this characteristic pattern. It is very pleasing to be able to determine the direction of polarization without an instrument in this way, an even obtain an estimate of its degree"

Hearing Test [Jun. 23rd, 2009|08:21 pm]
Plug a good pair of headphones into your PC and try the following website:


For me, I could only hear the 50Hz tone, the 20Hz one made a sound, but it was like a fuzzy "flop" noise repeating, not a pure tone.

In the high frequency range, 16KHz was surprisingly really quiet, and I couldn't hear the 17KHz one at all.

I'm quite sure it isn't the headphones, they're the Sony in-ear Fontopia ones that form a seal in your ear. Their sensitivity is 100dB, and frequency range sadly is between 6 - 23,000Hz

That means I've lost 3KHz of frequencies. Not too good for a 32 year old. =(

On the bright side - in a few more years I can buy bargain-bin $1 headphones that will have a frequency response covering far more than the frequency range I can hear. ^-^

Awwwwwww... [Jun. 23rd, 2009|11:43 pm]
I can't sleep because I've got a really sore jaw - a scratched gum's made my cheek/gum/lymph nodes on my face really sore.

So, passing the time online, I found this via Reddit:
