What's so weird about lightspeed, anyway?

Have you ever experienced that thing where you're in your car, stopped at a traffic light - you suddenly get the sensation that you're rolling backward, so you slam on your brake... but you already had your brake on, and you weren't moving! It was the car beside you rolling forward, but your brain misinterpreted it as your own - backwards - motion.

So, another mental image: imagine that you find yourself suddenly transported to a quiet, peaceful mountaintop. There's a monastery here, and Monks are quietly meditating. There is no sound, no …

The tension between classical and relativistic mechanics

Posted on Thu 09 January 2020 in Ramblings

When I was considering writing my post on time dilation, I expected precisely zero feedback... just on the basis that nobody would read it. I'm really pleased with the feedback I actually got, and you've all spurred me to write another post on the topic. So today, I'm going to give you a brief glimpse into what caused all this ruckus: Einstein's general theory of relativity.

If you remember, Einstein first came up with the special theory of relativity in 1905, and it took another ten years to get to …

I remember reading Stephen Hawking's A Brief History of Time back when I was about 16 years old - a bit over 20 years ago. I didn't even come close to understanding it then. I re-read it on Audible a year ago and I can report that I still didn't understand it at all. Either way, I've been interested in physics and spacetime for a huge chunk of my life, and I wish I'd spent more time on mathematics when I was younger, because I'd have really loved to be a …

Welcome to the Internet

Well, I'm finally here.

I've never really run a blog before... I did write a bunch of stuff back when I ran Gravity Computing; it just was never really "bloggy". That content has now been moved to Efficient Software, but I'll probably copy my parts back over here when time permits.

I really have no intention of running a blog, but I do come across interesting and challenging problems all the time, which I'd like to share with people who are, apparently, just like you.

I've got a couple things …
