There are some experiments that should be done only on a computer, only on a computer.
And lighting a fire in a carotid room is clearly
one of the fire in a carotid room is clear.
If the
K -Ploids are able to contain their fear and
move at a calm speed, then they are
able to evacuate the room in
an orderly manner.
Clustered around the door,
they gave one another enough space to allow a steady stream to pass
If people try to leave a crowded road too quickly,
they push up against one another
and become jammed around the doorway.
This is a panic state.
The time taken for a road to empty if people
initially decreases if people leave faster.
But above a certain threshold of speed,
corresponding to the appearance of a panic state, the emptying
time increases as people try to go faster.
If the peopleoids try to move at speeds greater than this,
the outcome is truly different.
Converging on the doorway,
the crowd of peopleoids press against one another, and friction takes
hold.
The peopleoids become locked, shoulder to shoulder,
unable to pass through the door
easily even though it stands
open in front of us.

So, although each peeploid is programmed to try to move faster,
this panicked state appears
in a fairly abrupt transition once the people
it's trying to move faster is joined.
Many nightclubs are dark
enough to begin with
And once smoke starts to fill the half,
it can become impossible to see more than a metre or so ahead.
Under these conditions,
people do not even know in which direction to run.
Helping and colleagues wondered
what might happen then.
One's instinct might be to rush around madly
and randomly looking for a way out.
It looks as though there is some form of non -equilibrium
phase transition between a relaxed an d a
Havoc, state of havoc,
making the evacuation very inefficient.
Making the evacuation very
inefficient.
If you see several people rushing past in a direction,
you might conclude that they
know something you don't.
