No, because the notebooks do not "contain" the work Einstein did, Einstein's brain contains it. So you'd need the living brain of a scientist as brilliant as Einstein. Which may not be that difficult; Einstein was good but he was also lucky - he glommed onto exactly the right Big Problem at exactly the right time. It's quite possible that there are any number of equally-brilliant scientists alive today who just happened never to find their Big Problem. The point remains, however, that paper and notebooks are not sufficient, you need the brain which actually contains the comprehension.

Moreover, since magic works by sensible-to-humans laws in the MoRverse, even if you copied the brain you'd have to use the original in the potion, and you only have one of those. The reason being, the copy hasn't "done the work" even though it contains the comprehension; and you can only get back out the work that was put in. This of course makes no sense, information should be information, but the laws of magic were apparently designed by a human.
