Drake Equation T shirt is perfect for the science geek in your life. Share Drake's equation for estimating the potential number of intelligent civilizations in a galaxy by wearing this T-shirt. Drake’s equation was used by Gene Roddenberry in 1964 in his pitch for Star Trek to justify the large number of inhabited planets in the show. He did not have a copy of the equation so he made up his own. Roddenberry’s formula was as follows: 𝐹𝑓2(𝑀𝑔𝐸)−𝐶1𝑅𝑖1×𝑀=𝐿/𝑆𝑜. Wear this T-shirt to set him right! Black 100% cotton T-shirt.
