The older lady in the glasses is watching the younger lady do her experiment/. This older lady doesn't actually pertake in any part of the experiment but watch to make sure that everybody else is on track. The experiment they are working on is to find a new discovery in science/ to figure something out new that hasn't been figured out yet. The younger lady and older lady had had some tiffs in the past...the younger lady doesn't like the other watching because she thinks that she knows what she's doing and that she doesn't need a babysitter. But this time, in this picture, the younger lady doesn't notice that the older lady is watching b/c she is too consumed in her work. Thought the younger lady will be mad later b/c the older lady will take all the credit when some worthwhile results come about.
