Through two doors at once

A great read that was understandable enough to appreciate how gosh darn fascinating this area of quantum mechanics really is.

In terms of difficulty, there were parts that were easy to get, parts that I got once I went over them a few times, and parts I had to throw up my hands and accept it was out of my reach, luckily those were relatively rare.

Most mindboggling part was the experiment that directly proved the non-locality of the double slit experiment applies to time. As in...like...time travel...has been scientifically proven.

I don't know what to do with that information.

The double-slit experiment was first performed in 1801, and is still being used to learn more about physics today, which is a pretty amazing fact. This book charts the history of the experiment and obviously talks a lot about quantum physics along the way. As far as physics books go, it was a fairly breezy read, although somehow it managed to drag a bit at the end. Worth reading if the idea of quantum entanglement across hundreds of miles is interesting to you.

Another once-over of modern quantum ideas, built roughly around the double-split experiment. Lots of great ideas and filled in many of my (nearly infinite) gaps of knowledge.

However, despite having studied physics at university and having read (mostly 'listened to') many of these physics I got lost some times, which is OK. But worse, it somehow got kinda boring.

Three stars

I liked how the author ties together multiple areas of research within the story of an old experiment. I appreciated that the author did not dumb down the Physics or dilute it. I have read about the history of quantum mechanics before, but I was still astonished by the depth of meaning and all the possibilities behind quantum mechanics and the results from the double-slit experiments. 'Mind-boggling' is too light a word to describe it. Kudos to the author for capturing the essence of this area of research while preserving the mystery.

This one is great even if you've read about double slits before simply for talking about 'interactionless measurements' (such as the hypothetical way of detecting a bomb that explodes if a single photon hits it, without shining any light on it to find it!) and quantum erasers in detail.
