I second Feynman lectures! It is a delightful introduction to physics.
Susskind's theoretical minimum series is also a good starting point: http://theoreticalminimum.com/courses
The Feynman lextures are must if someone wants to develop intuitions in physics. Volume 3 (quantum mechanics) is a bit difficult for new learners or undergraduates, but I absolutely recommend reading vol.1 & 2.
