I suspect that if you're studying the History of Physics, as opposed to just physics, you've already got a special interest in the subject. And if you're not, you're not replying to what the earlier post said, which referred all kinds of _history_. The original post, I think, was broadly about trying to engage people in the history of something they're not already interested in. For that, the device seems reasonable. At least it does to me. But maybe that's because I actually did work backward from Led Zeppelin, to the Stones, to Muddy and Wolf, to Robert Johnson and learned to love them all. But if you started me on Johnson, or worse, Charlie Patton with those horrid recordings, you'd have lost me immediately.
