★☆☆☆☆
One of the most inaccurate and obnoxious STEM-pretend book ever written
The author goes into extreme detail in trying to describe simple experiments and makes outrageous mistakes. Take, for example, the pendulum, the period of which is claimed to be independent from its amplitude... This is wrong because it is! The main character measures the period of a pendulum that swings for 10 minutes or something like that. Just take a yo-yo and let it swing. Will it swing for 10 minutes? It will not! It will stop in a minute or so. I mean - how difficult is to try out something like that before you put it on paper?
Then, a few pages later the author writes that the centripetal acceleration is inversely proportional to the radius of rotation. I guess the author had in mind this formula: a=v^2/r. Well, v, the velocity, is a function of the radius in this formula v = w*r where w is omega, the angular velocity, which is independent from the radius. So, in fact, the centripetal acceleration is equal to w^2*r. It is directly proportional to the radius...
Every other page contains a description or analysis of something that simply contradicts the world as we know it. You might argue - who cares? Actually, we all do because if you remove the science from this book there will be nothing left. To me, the pendulum and the centripetal acceleration examples are equivalent to stating that 2+2=5. Unfortunately, on every other page in this book we see 2+2=5, then 3x4=16, and so on and so on. You cannot read this book without pulling hair from your head. There were supposedly multiple consultants involved in checking the accuracy of this book. But it appears that none of them stood up and said - man, this is wrong, you have to change this or just do not write this at all.
I am not discussing modern physics and relativity. That stuff is beyond comprehension because it appears to be written by an insane person. Annihilation of neutrinos-antineutrinos, some membranes that are impenetrable or semipenetrable by neutrinos (I already forgot)...
All the science-related material in this book - from the "science" people, their dialogs, and their relationships to the actual science itself is just terrible. Unreal, unbelievable, grossly incorrect!
I do not understand how this book can be rated better than 3 stars even by those who managed to get through the impossibly wrong science. This is a work of an average student. Actually, much below average.
