With only two more installments in the series to go (as I said, I'm reading final copies for their e-book release and reviewing them, as I enjoyed this series as a kid) - this may be the BEST Danny Dunn book yet!

Despite the title, the book does not involve *actual* invisibility (in the "bending of light" sense - and Prof. Bullfinch even explains why that's highly unlikely to work), but what's surprising is that the book actually deals with virtual reality/videogame technology, military drones, s

A nice revisit to one of the Danny Dunn series that I had read in my youth. It's 3.5 stars for me, because I have fond memories of this from my youth. As an adult, the situations lack a modern maturity, and the technology is _way_ out-of-date

An interesting occurrence in the Danny Dunn series is that Danny, Joe and Irene do seem to age as the series progresses (based on changing seasons within books, and the fact they seem to have spent several books with a single teacher, as in elementary school

Good lord, I'd forgotten all about this series.

This particular one is the first one I came across, and probably the best one of the series (not that I ever read them all).

The general idea is that Danny is a boy very much interested in science who lives with his widowed mother and Professor Bulfinch, who employs Danny's mother as housekeeper. The Professor, of course, serves as a mentor/father-figure as well as the source of all the super-tech devices the books are built around.

It is a credit to

A good book from a set I read in my childhood. The writing may not be brilliant, but the story still gives the reader a chance to set their imagination free. What if technology allowed us to do the impossible? To defy gravity, hear aliens on other planets, or spy on others and speak to them without being seen? I suggest this as a good book for children still in grade school.

I was kind of shocked with how well this book holds up. It's not just a fun "boy's adventure" either. It could have been written today in fact. The basic story involves Danny's professor friend building a tiny drone that's controlled by the equivalent of an Oculus Rift. When the government finds out about the "Isit" they take Danny and the Professor prisoner in their own home.

The book is clever, fun, quick, and technically spot-on. The world of Danny Dunn looks familiar 50 years on due to the au

An enjoyable book found at a thrift store. The story of a young boy named Danny Dunn and the eccentric professor who lives with his family, as well as his two friends Irene and Joe. This is one of a series of Danny Dunn books from the 70s. I have only read this one. It's reminiscent of Tom Swift stories.

In this novel, the professor creates a machine controlling an electronic dragonfly. This gives its user a type of invisibility.

Read this as a kid and vividly remember marveling at the concept of telepresence, though it's not to referred to as such, depicted with the helmet-gauntlet-controlled remote-sensing robot dragonfly.

Recently re-read this with my own child, age five, and we both loved it.

This was written in the early 1970s as sci-fi, but has some striking relevance to modern-day issues -- namely drones, privacy, and government surveillance.
