Dr. Kaku is an eloquent speaker for Physics and he publicized sciences and raise global awareness of controversial issues on science (like nuclear weapons, global warming, etc.) I am not questioning the validity of his popularity. I am just curious, what has he done on the theoretical side for Physics? Has he come up with any theory on any particular area of Physics? It feels like he went all over the place for me. Also he claimed he built an atom smasher which I guess was a Cyclotron in his backyard. I want to know if that's a little gimmick pulled by his advertising agent or he actually built one? I think it's impossible to power up a Cyclotron with house-hold consumption rate of electricity. I mean he can't pull out enough juice from those wall outlet to power up those powerful electromagnets to guide a beam of particle to smash into each other. Also how would he read the result without high-end computational methods? The data would probably be all over the place? Maybe he did build one, was it a successful attempt or just a fail attempt? I am just curious and any discussions or comments are appreciated.
