We are stuck with technology when what we really want is just stuff that works.

Albert Einstein

It has become appallingly obvious that our technology has exceeded our humanity.

Jose Manuel Rodriguez Delgado

Can you avoid knowledge? You cannot! Can you avoid technology? You cannot! Things are going to go ahead in spite of ethics, in spite of your personal beliefs, in spite of everything

Sergey Brin

Technology is an inherent democratizer. Because of the evolution of hardware and software, you’re able to scale up almost anything. It means that in our lifetime everyone may have tools of equal power.

Douglas Adams

Most of the time spent wrestling with technologies that don't quite work yet is just not worth it for end users, however much fun it is for nerds.

Ohm's law

Ohm's Law    
For a fixed metal conductor, the temperature and other condition remaining constant the current through it is proportional to the potential difference between conductor ends.

V/I = Constant


V  = volt 
 I  = Current
 R = Resister of the conductor between the two pints considered

we can apply V=IR  Linear resistors only.
