So, part of its popularity as the world’s most famous physics formula is that everyone kind-of gets it - energy equals mass times a constant – well OK a constant squared, but that is still a constant. But why is that constant a velocity – and why is it squared?</p> <p class="p2"> </p> <p class="p1">We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.<span class="Apple-converted-space"> </span></p> <p class="p1">Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p class="p1">Share the podcast with your friends and send the Patreon link to them too!<span class= "Apple-converted-space"> </span></p> <p class="p1">Every bit helps!
