## The West Coast Metric is the Wrong One

I’m trying to get back to blogging about quantum mechanics slogans, this one is about relativistic quantum mechanics. I’m hoping it will stir up more trouble than my last East vs. West one. If you’re doing calculations in relativistic quantum … Continue reading
