From social media to massive financial institutions, we live within a web of networks. But how do they work? How does Googling a single word provide millions of results? Marc Samet investigates how these networks keep us connected and how they remain "alive."

Translate into Russian:

go viral, behavior, within, evolving, occur, neighborhood, define, node, expand, power function, amplification, logarithmically, accelerate, value, parameter, emerge, emergence, increase, accomplish, derive, reference, expansion, apply, acquaintance.

a) Networks are collections of links which combine by specific rules and behaviors if they are alive.

b) Despite the logarithmic expansion of your network, the laws of nine degrees of separation still apply.

c) A power function is a mathematical amplification mechanism, which over specific and very small ranges, accelerates changes logarithmically.

d) What Google has cleverly accomplished is a real-time mathematical model for how to predict the emergence of growing connections among billions of search terms.

e) The algorithm Google derived collects the number of references to particular search object.
