Why we need Samadhi to attain enlightement?
Is widom something like that ? What is the connection between samadhi and wisdom ?


There's a big difference between wisdom and being book-smart. If you have a fish tank full of muddy water, and if you constantly shaking it, will you be able to see through the tank and detect the objects on the other side? How about letting the tank settle on a solid level ground for a while, then see through it? Sila is that solid level ground. Samadhi is the "settling" of the tank, Wisdom (or penetrating insight) is the "seeing through" to the other side.
