I showed another example of suicidal behavior in bees. Honey is a predator, it is Necessary to sacrifice their lives for most of the string But bees are highly social insects. Other wasps, ants and termites. I’m generally not an object of social insects troops dead bees would just like to study. “Running in social insects is surprisingly consistent with the altruism that apparently is exactly the action and they especially kind, and very popular. Sting suicide mission to embody the miracle of restraint.” In colonial The ant traps (honey pot ants), with the level of other workers not to work, in a move filled with food, shifting like light bulbs. Day nest hanging on the bulge of the belly of their banking and other workers as food, in terms of our human view, workers are present as their personality for the benefit of the group and who no longer to, Will has been Explicitly prohibited. Ants, Which reflects a higher level of personality in the social life of bees and termites. According to very rigorous standards of food distribution, we can further say, that they share a collective stomach. Bees, in order to exchange information “dance” if it is known, they are through chemical signals. These tools, that collective action is more efficient and seem to block his own nervous system and sensory organs.

This is, we include some basic principles of various forms of negative feedback may call the principle of negative feedback. In general, according to him, but this effect: A measure of a device specific machine “goal,” it is currently a gap “request” if you can measure the state of the conscious supports the objective.
This structure, a machine means that the gap can be run more quickly and it is time. This machine can automatically reduce the gap - called a negative feedback point on it - “request” status, the machine has reached you can stop working automatically.
Governor of the fire, which is equipped with a pair of balls, they rotate the driving force of the steam engine. These two objectives are two active connections at the top of the lever arm was set. With the increase of ball speed, centrifugal force, the gradual acceleration of gravity X lever that is connected to a machine that is offset by the results of the lever closer to the level of the lever arm, a level that ensure gradual decrease couples to provide a pair of valves close. Therefore, if the machine is running too fast, you reduce the amount of feed speed of the machine, a pair of late.
Conversely, if the machine runs too slowly, the valve increases the amount of steam supplied to the faster speed of the machine automatically. However, excessive amount of delay is probably because, in many cases, please adjust the relationship between the target of these vibrations. To compensate for this shortcoming, engineers are trying to add some equipment to reduce the magnitude of the vibration time.
