A lot of this is now out of date (published in 1994). But the "Electricity in tge Future" section was an interesting mix of prescience and ridiculousness.
We liked it, but it was a little hard for Olivia to understand in some parts. This may just be because it isn't Olivia's favorite topic, so she wasn't really hungry for more info. Definitely has good descriptions and illustrations.
Great book for getting a deeper understanding of electricity and magnetism. Thorough and simplified. I did not read it in one day, just forgot to add it. Would be a bit of dry reading. Broke it up over a few weeks while working w/ curriculum.
