Schrodinger wave equation coffee mug

The mug arrived on time and was packed very well to prevent damage during shipping. However... I suspect that I am not the first to point this out but the equation is incorrect. The triangle preceding the right parenthesis is upside down. This character should be printed with the pointy end down and it should be raised to the power of two (i.e.squared). In mathematics, an upside down triangle that is squared is called the Laplacian operator and is shorthand for a longer partial differential equation that operates on the wave function (greek letter psi). You should check Wikipedia before offering novelty mugs that include math. I did not notice this error before purchasing but now think that the mistake is hilarious! Aside for the humorous error, the mug was printed beautifully. Please let me know if you correct the math error and I may purchase the corrected version and have a nice set.

I got this for my best friend who is going to grad school for computational chemistry because this equation was the backbone of our pchem II class, which brought us closer than ever. And he's a coffee lover, so it worked out swimmingly, I think. Love this mug. Fits in the drink holder in his car, keeps the coffee warm, and it's sturdy. The printing was evenly spaced, large, straight, and clear.

I like to buy and review my own work to ensure you get an outstanding product and I’m happy to give the Primary Colours Beach Football Mug 5 stars because it meets my expectations completely. Pleased with it I am. Zazzle mugs are well fabricated, microwave and dishwasher safe. And this yellow red and blue panoramic wraparound motif is sealed with a durable and sparkling Orca polished gloss glaze finish. It’ll never rub off! The size and energy of two jostling figures and a burly goal keeper fit the mug's circular shape well. There's momentum in the carousel effect as the two jostling figures repeat and move right around the mug and meet a burly goal keeper. Big sharp original images precisely drawn and delicately captured in blue and red with plenty of bright yellow! An ideal gift for anyone who plays ball! A fun gift for all beachball and football fans. A pair with the Retro Grey-Grain Beachball Player Mug. Available in two sizes and several styles including Black Ringer, Travelling, and Stern.
