Invention: Dust buster

Invention: Dust buster

I student invents a new way to monitor dust levels in dark places.
the student of Yamaguchi University in japan, called Masato Shinji, says that a camera does the job
it takes a picture with a flash and dust appears as white dots in the image
and a software counts the dots to give a percentage of the dust in the range of the flash gun
and from that the density of it in the air.

that helps to know how safe are the mines and tunnels for the workers in it.

the story of stuff

a nice video with explanation about the production circle of stuff

like tvs, ipods and other stuff

and how not controlling them creates a crisis

it is very simple

and you get a bueatiful life

in my country we have nearly the same thing it is human nature

this video makes me think more about consuming and I'm already good at it

this video is  related to global warming because global warming comes from this story

Boy's school bathroom death attributed to game

Police: 'Run and jump' game may have led boy to get caught on hook

"A 7-year-old boy found dead hanging from a hook in a school bathroom "

They said it is possible that he was playing run and jump. It is where children jump from bench to bench trying to touch the ceiling. the boy was excused to go to the bathroom but didn't come back and when they looked for him they found him hanging. there was a possibility of suicide but there was no evidence.

The title grab my attention. it was something weird for a boy to die at school.

I feel sorry for the boy and I think the school should be careful because chlidren don't know what are they doing and if it is dangerous or not.

I feel that it was a mysterious because children were always playing the game but the same incident never happened

what's up
