I have free time so I Would like to spent it by visiting musuems in Zurich...do you recommend some and inform me if there is special discount for entrances on certain days,especially for women?
Thank you...

The Swiss Museum Pass is a good buy:

And there are also unique museums, like:

Executioner’s Museum in Sissach & the Swiss Museum Pass

Not free, not valid with the Museum Pass as well.

my favourite is the Kunsthaus, with its fantastic art collection spanning centuries.
currently (but only until mid january) the Nahmad Collection shouldn't be missed. check out their excellent website for information on guided tours on various themes and interesting offers, like a very convenient year membership.

We've had a thread on Zurich museums.
Museums

Very close to Zurich, in Winterthur, you have Villa Flora. It houses one of the best private collections in Switzerland, with focus on 19th and 20th century paintings (Cezanne, Van Gogh, Matisse, Maillol, Bonnard, just to mention a few). Both the space and the collection are an absolute delight to visit, and worthwhile the trip.

Discounts especially for women?

As opposed to all those cultural centers that offer reduced rates for men and certain other bipeds?

In the Landesmuseum a fascinating exhibition of the Braginsky Collection -
Books from 12th century etc.
