## Customer Reviews

### ⭐⭐⭐⭐⭐ Great shirt!
*by O***S on September 24, 2017*

Great shirt, good quality, good fit.  Having fun with who will recognize Einstein's famous mass/energy equivalent formula.  Of course there's always the science 'expert' who will tell you that the small m in Einstein's equation is for mass, not matter.  Then just ask them what the standard model tells us about mass and matter.  Dr.Tyson's seldom wrong.

### ⭐⭐⭐⭐⭐ Love it, but...
*by P***K on June 17, 2018*

Love this tee, but once I got it home, I wondered if people might think it was mocking Black Lives Matter. I couldn't wear a sign around my neck saying hey, I got this from a brilliant African-American scientist's web site. So I wear it at home.

### ⭐⭐⭐⭐⭐ He really enjoyed the wording on front
*by B***N on February 14, 2018*

A gift for grandson. He really enjoyed the wording on front. He will wear it to science class! Also his school color is purple!
