Science-inspired art by Sienna Morris, drawn entirely with numbers and equations by hand. Based in Portland, Oregon, Sienna is self taught in science and art, and uses her Numberism technique to process what she's learned, illustrating the data where it lives. 

She offers original work as well as fine art canvas and paper prints, and clothing of her work. 


Expect additional delay for the month of October while we move to our new location in Cathedral Park Place in St. Johns. Orders should arrive in 4 weeks unless we already have the print in stock.

Great Coronary Vein: C8H11NO3 Norepinephrine 

Superior and Inferior Vena Cava: arteriovenous oxygen difference a-vO2 diff = Ca – Cv 

AV Node: Normal Firing rate= 40-60 per minute. 

SA Node: Membrane Potential Em = g’K+ (-96 mV) + g’Ca++ (+134 mV) 

Outer view of muscles of the left atrium, left ventricle and right ventricle: Stroke Volume (SV) = EDV – ESV

Pulmonary Artery: Ejection Fraction (EF) = (SV / EDV) × 100% 

Aorta: Cardiac Output (Q) = SV × HR 

Cardiac Index(CI) =Q/ Body Surface Area (BSA) = SV × HR/BSA 

(near Aortic Valve): Systolic pressure gradient across valve – AVA(cm2) = CO (l/m)/√mean Gradient (mmHg) 

Pulmonary Veins: Oxygen Content of Blood = [hemoglobin] (g/dl) x 1.34 (ml O2/g of hemoglobin) x saturation of blood (percent) + 0.0032 x partial pressure of oxygen 

Inner view of the right Atrium: Vimentin RefSequence (mRNA) : NM_003380.3 RefSequence (protein): NP_003371.2 

Other data: 250=350gm 9-12 oz 2.5 billion beats per 60 year lifetime. There are hidden words and numbers not listed here, that you can find over time the longer you look at the piece.
