I don't think much has been added to thermodynamics or mechanics or any other subject within the last 10 years!
That's taking things too far. Half of the facts in a 45-year-old textbook are still valid. For medicine, that is - for engineering, probably more; Archimedes and Einstein are still relevant.
Totally wrong!!
That's about as stupid a rule as I have ever heard. Go read Dickens!
That's stupid. Just plain stupid. If the only books you'll read are less than 10 years old, then you're not going to read many good books. Marcus Aurelius placed a heavy emphasis on understanding first principles in order to have a complete understanding of anything, but you wouldn't know that because Marcus Aurelius' book is more than 10 years old and thus you've never read it.
Doesn't work for the Bible or literature, may work for science works in telling you exactly what the logic of the discovery at the time of discovery was. Books of people telling what they experienced are more valid than history books looking back from now or the last 10 years.
In other words, your rule has a lot of exceptions.
There is nothing new under the sun.
