You need to know how to do your math without a calculator... You never know when you may be stranded on some beach and need to do some math!

“I had a feeling once about Mathematics - that I saw it all. Depth beyond depth was revealed to me - the Byss and Abyss. I saw - as one might see the transit of Venus or even the Lord Mayor's Show - a quantity passing through infinity and changing its sign from plus to minus. I saw exactly why it happened and why the tergiversation was inevitable but it was after dinner and I let it go.”

Sir Winston Churchill

"I advise my students to listen carefully the moment they decide to take no more mathematics courses.  They might be able to hear the sound of closing doors" 

  James Caballero

"If you want to build a ship, don't drum up people to collect wood and don't assign them tasks and work, but rather teach them to long for the endless immensity of the sea." 
Antoine de Saint-Exupery 

"Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true." 

  Bertrand Russell
