About This Design
Shirt - pi formulation
Pi is arguably the most important transcendental number known to man. Defined as the ratio of the circumference of a circle to its diameter, this number has fascinated mankind since antiquity and continues to delight mathematicians with intrigue to this day. Over time this number has slowly yielded its secrets. First, it is an irrational number and cannot be represented as the ratio of two integers. Beyond that, it is transcendental and cannot represent the root of any polynomial with rational coefficients. Open questions remain. Celebrate the wonder of mathematics on National Pi Day. This attractive shirt has many different formulae featuring pi. The most famous is Euler's formula, the magical relationship that combines two transcendental numbers with the imaginary unit modulus to produce an integer. There are both series and integral representations for pi. You will see Machin's formula, the Riemann Zeta function, the Madhava-Liebnitz series, the BPP formula and many others. This is an ideal gift for your favourite polymath. The design is open allowing you to change size and colours or to customise with a name.

Delivery was just on the last day's of Delivery estimate,but within E.T.A just,So No complaints.Cotton is of Good Quality.Fit is Prerfect to 5% bigger. Very Good but Not perfect,but at Ordering would have taken V.Good AnyDay!!Only Slight thing(as NO Bleeding,NO Smudging or ANY probs with acctual writing,is that the Red/Black and T-Shirt Colour isn't as Bold/Bright as in picture.BUT! When i took pic's of T-Shirt on my Phone for this review,it again looked like Bolder/Brighter Colours by 10-15% than in reality.......

I really like the design but I'm not sure the white base really took as you can see pink through her fur/bikini. So that was a little disappointing. That's more on the printing side though than the actual design, the design is really great, Cutey Bunny looks so beautiful! If you're thinking of getting this then I'd say just go for a white T-shirt and you should be fine.

The T-shirt is great quality! The cotton is thick and does not lose its shape. I bought this as a gift last Christmas and since then it has been washed many times and I haven't seen any stretching or tears. The size fits perfectly. The printing is excellent. The colours and the design were exactly as shown in the picture. One year after, it hasn't faded due to washing.
