# Nerd 4

.

I thought it would be useful if I explained what a nerd was. What I came up with was: someone who doesn’t expend any effort on marketing himself.

A nerd, in other words, is someone who concentrates on substance. So what’s the connection between nerds and technology? Roughly that you can’t fool mother nature. In technical matters, you have to get the right answers.

# Annus mirabilis

.

Annus mirabilis is a Latin phrase meaning “wonderful year” or “year of wonders” (or “year of miracles”). It was used originally to refer to the year 1666, but is today also used to refer to different years with events of major importance such as 1905 when Albert Einstein published his breakthrough four articles on Physics.

1666 – Isaac Newton

In the year 1666, Isaac Newton made revolutionary inventions and discoveries in calculus, motion, optics and gravitation. As such, it has later been called Isaac Newton’s “Annus Mirabilis.” It is this year when Isaac Newton observed an apple falling from a tree, and hit upon gravitation (Newton’s apple). He was afforded the time to work on his theories due to the closure of Cambridge University by an outbreak of plague. Going to his country home, he thought about many things that, in Cambridge, he did not have the opportunity to do with such devotion.

1905 – Albert Einstein

The year 1905 has very much been linked to the term “annus mirabilis,” as Albert Einstein made important discoveries concerning the photoelectric effect, Brownian motion and the special theory of relativity. These articles were published in Annalen der Physik.
