如果我睇相對論,應該睇廣議定狹義先?

The Special Theory of Relativity (狹義相對論) was published in 1905, whereas the General Theory of Relativity ( 廣議相對論) was publishe din 1915. Hence, it would be better to read literature on the Special Theory first.

Apart from this, the Special Theory is more understandable than the General Theory as the latter involves much difficult mathematics.
