View references and resources for this episode. Welcome to Ask Us Whatever. I’m Joe Sorge Some people have questioned whether the clock-offset concept that I’ve relied on in the last two episodes is real. Let’s look at an article published in the journal Science in 1985 by GPS navigation experts at the National Institute of … Read more
Welcome to Ask Us Whatever. I’m Joe Sorge. Well, the comments I received in response to Episode 7.1 showed me that many people do not understand Einstein clock synchronization, nor its profound implications. And because Einstein clock synchronization is essential to understanding special relativity, we need to shore up our understanding of this very unusual way to … Read more
Hey! Welcome to Ask Us Whatever. I’m Joe Sorge. So, we’ve been posting our videos, nicely trying to show that Lorentz and Einstein made some mistakes; and of course, we’ve begun to get some expected blowback. Here’s an excerpt from a comment from someone called AnticitizenX: “You seem to be under the naive impression that physicists just … Read more
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
