WORTH NOTING ON TV

SUNDAY The Tonys (CBS, 9-11 p.m., ET): In the hyped world of big-time awards, it's the theater's night - traditionally the most intelligent and best-done of the genre. Live from New York's Lunt-Fontanne Theatre and loaded with stars, the 44th version of the event is hosted by Kathleen Turner. MONDAY Myrna Loy: So Nice to Come Home to (TNT, 8-9 p.m.): She was born in Montana and for a while type-cast in exotic roles before becoming the model wife and mother of the American screen. Narrated by Kathleen Turner and created by film critic Richard Schickel, this special uses newsreel footage, anecdotes, and lots of clips from Loy's memorable roles.

WEDNESDAY Smithsonian World (PBS, 8-9 p.m.): Its philosophy is murky and its interpretation much debated, yet quantum physics has reshaped the way science views reality. If you think that's odd, `The Quantum Universe' agrees, and spends its time exploring the theory. An 11-year-old girl narrates - the producers felt that would somehow make the awesome material a bit more accessible. American Playhouse (PBS, 9-11 p.m.): A Blackfoot girl is kidnapped from the mountains and forced into a Christian school, where they try to talk and beat the Indian heritage out of her. This kind of horror happened a lot in the earlier part of the century, as dramatized in `Where the Spirit Lives,' a story laid in Canada but whose theme was deemed broad enough to be included in an ``American'' series.
