The following is a description of a demonstration.

Step 1: A newspaper is placed over a meter stick that is hanging over the edge of a table halfway.

Step 2: At the edge of the meter stick that is hanging over the table, it is given a sharp hit. The meter stick breaks, but the newspaper doesn't move!

Describe what is happening in this demonstration in terms of pressure.

(hint: think atmospheric!)

Good Luck for the winner of the quickest best answer.

When the cube placed on a large sheet of paper, the wet paint will imprint a colored square on paper. The cube can be flipped over any of four bottom edges, imprinting another color in adjacent square.

Using chess notation, if we place the cube on square d4, is it possible to paint e4 in the same color as d4, flipping the cube as descibed above?

still till today i can't forget this as if it was carved into my brain, it is some kind of memory i canot escape and keep seeing it all the time.
When i was 6 years old, my father had a tough fight with mom, and he went into the bedroom and started crying, i remember he was talking while crying to my older brother, i stood without they notice me in the corner of th room which was dim lights almost dark, and i started crying, suddenly i wanted to screem as a sympathy to my dad's tears, but all of a sudden i see everything like a video recorder rewinds all events infront of me, for a short of time, untill i was still standing in the room but my dad was asking me why i am standing here in the corner alone and why i am tearing. when i asked him you were fighting with mom, he doesn't recall such an incident, untill it happened and it opened a hell lot of questions, from both mom and dad as to how i knew about the fight?
Please help, does any one has a scientific explanation to this?
