Question: Rated for 3+ but my 2 and 3 yr. olds both play with this. While the kids like playing with this, I like that it can grow with them. It has basic tools for younger children: rolling pin, presser with three tips, pizza cutter, safety scissors, play-doh knife. But it also has tools/items for older ones: bead making, art molds for pictures and "sand".The only con is the mat. It's cheap plastic. Sounded great on the box in the store, but ends up crinkled underneath them and not protecting the floor. Stick with using and old sheet or vinyl table cloth from the $1 store.

Answer: Positive


Question: I think this is a case of my expectations being too high. I was so encouraged by the great reviews of this product, I really was expecting a miracle. After only wearing this twice, it is stretched out. At first, I thought perhaps it would regain it's shape after a few hours but nope! It's no better than a cheap, fashion corset. It will smooth things out so there's less bulging under the clothes but I was looking for a real "waist trainer", something that would go on tight and STAY tight. Considering I found this product when I searched specifically for "waist trainer", I would say the claims of this product are misleading. It is shapewear, it is NOT a "cincher" or a "trainer".

Answer: Negative


Question: If you are intrested with studing statistical mechanics then start here. Hill starts from the defintions and postulates of thermodynamics and then moves into applications and problems. You will need to understand Diff EQ for this book.The first chapter took me a week to read and work out the math but then I red the rest in 4 weeks. It is a hard start because Hill develops your background before starting with applications of the theory. I really began to grasp the subject after reading this book. Ohter books will not lay the mathout as well as Hill does. It is a hard read because Hill is so thorough, but the rewasd is well worth the struggle. It is a great introduction and I suggest all of Hill's Stat mech book. Another great bargin from DOVER PRESS.At the price I recomend it to all graduate chemical engineers and chemists

Answer:
Positive
