If this curve had shown
the temperature of
the reactor in Chernobyl nuclear power plant,
shouldn't the security
officer have pressed the alarm button,
so that people could leave the site, as long as there was still time?
If the gauge had shown
that in the steam boiler of the ship
the pressure was continually increasing faster and faster,
shouldn't the captain
have given the command
to abandon ship, before the boat blow up?
