Mathematical Drawings

When I first set up this blog, one of the hardest parts was finding a name that suited my interests, personality, and what I intended to write about.

Inspirational Geek seemed to fit well, and if there was a ever a post to sum up a combination of those aspects altogether it is probably this one.

Hitting the nail on the head is Rafael Araujo and his self-titled “Calculation work which encompasses the ‘inspirational geek’ sentiment more than most.

Using only a pencil, a ruler, a protractor and a compass Rafael produces the most intricate and visually stunning mathematical artworks.  And no computer in sight.


The flat paper space is brought to life in a complex and geometric 3D world.  We all know that there is maths in nature, my Doodling In Math mini series demonstrated that, but these drawings prove it in an incredible way.

Butterflies rise from the page and shells spiral up from their base with expert realism, and all hand drawn.  No CAD, no software, no Wacom tablet, just traditional drawing tools.




Spectacularly complicated images.  I wouldn’t even know where to begin myself.




If this doesn’t inspire me to get back into more regular sketching then I don’t know what will!




Many more works on his site here.

    As a mathematician and a photographer, this may be the Best Post Ever. The nautilus shell is just too awesome … ugh, I love logarithms.

    Breathtaking. I should go to sleep but this makes me want to open up my sketchbook and spend the night drowning in art instead.
