Quote of Day

• Mathematics is the gate and key of the sciences … . Neglect of mathematics works injury to all knowledge, since he who is ignorant of it cannot know the other sciences or the things of this world. And what is worse, men who are thus ignorant are unable to perceive their own ignorance and so do not seek a remedy. (Roger Bacon [Opus Majus, bk. 1, ch. 4 – ])
