And don't get started on comments about the stock market, or quantitative trading. I'm not an expert on physics so I'm unable to judge, but I am a quant and work at a quant firm and it's absolutely clear most comments discussing stock markets, HFT, automated trading and the like are coming from people with only a superficial understanding of the subject. And what's worse is like you say... the comments are made with such certainty that unless you knew better, you'd think it was experts making authoritative claims on the subject. There's a principle that says take a subject you're an expert in and see how poorly journalists explain it, then consider that they're likely just as poor at explaining subjects you're not an expert on. Same principle likely applies to HN.
