"modern c++", checked amazon. there are 5 out of 5 on the first line, and more in the list, with many variations.

And the Modern Age ended at the time of the Industrial Revolution.

Books are an understandable phenomenon. They were supposed to disappear before the stuff they describe stops being valid. But we have a nasty tendency of naming permanent things "modern".

But anyway, it reminds me on how if you want a real textbook that covers a math or physics subject with all the details, you need to get the one named "fundamentals of X". If you go and get the "advanced X", it has a superficial and incomplete description that won't help you with anything.

As a non physicist, I'd like to see some titles. I feel that the sixties were a watershed decade and am interested in examples.
