Can anyone suggest a video or book that will allow the layman to grasp physics concepts in a conceptual manner?
One big foundation of physics is the law of gravitation and Richard Feynman explains it very nicely but with a lot of insight: The Character of Physical Law
There are of course hundreds of other videos and books describing the concepts, just pick one that suits your style.
For particle physics, a not-too well known but astonishingly good semi-popular book is t'Hooft's "In Search of the Ultimate Building Blocks". It's unique in that, in addition to the usual topics - unification, quarks, Higgs mechanism etc, he treats topics such as instantons and the triangle anomaly. Unheard of in the pop-sci realm !!
If you want to have "all subjects" covered I would recommend Feynman's Lecture on Physics. But you would not find anything about recent developments (this book is a classical from the 1960ies).
