Hey, welcome to Ask Us Whatever. I’m Joe Sorge. Well, I thought we’d do things a little differently this time. We’re going to do some garden variety relativity before we go into the studio and work out some math. So anyway, if you were to read Einstein’s 1905 paper on special relativity, he talks about … Read more
Welcome to Ask Us Whatever. I’m your host, Joe Sorge Before we begin, a word of caution. I’m going to deviate from orthodox teachings in this episode. The questions I’m about to raise and the answers I’m about to raise and the answers I’m going to provide are going to seem radical. Most people think … Read more
Welcome to Ask Us Whatever. I’m your host, Joe Sorge This episode will make a lot more sense if you’ve watched the previous episode. If not, I would suggest doing so. But if you’re already an expert on special relativity, then please, forge ahead. In the last episode we learned that Michelson and Morley were … Read more
Welcome to Ask Us Whatever. I’m your host, Joe Sorge. In the last episode we learned about time dilation, and why all observers believe that the speed of light is constant. And while the explanation for time dilation is a good one for clock elements that move side to side with respect to the direction … Read more
Welcome to Ask Us Whatever. I’m your host, Joe Sorge. This is Part 2 to our time dilation videos. In Part 1 we covered some of the formal mathematical background. Here, we are going to cover some practical implications. Now let’s look at the differences between a light clock on a moving train compared to … Read more
Welcome to Ask Us Whatever. I’m your host, Joe Sorge. In the prior episode we showed that events may appear to be simultaneous to one observer, but not to another. Observers within the same moving reference frame may need to adjust their clocks to agree on when events occur. In this episode, we explore something … Read more
Welcome to Ask Us Whatever. I’m your host, Joe Sorge. So, let’s take the next step and describe how motion can change our perception of a sequence of events. Again, we’ll use sound to illustrate the concepts before moving on to light and special relativity. Let’s assume a band wants to perform on a train … Read more
Welcome to Ask Us Whatever. I’m your host, Joe Sorge. You know, most of us have become reliant on the GPS systems in our smartphones to get places. But did you know that without the adjustments to time and space predicted by Einstein’s relativity theories, our phones would take us to the wrong locations? That … Read more
