Well said Johnson. Mary and Jacob need to grow up before typing. Dr. Kaku is a great scientist, if you want to hear science talk directed at children, go listen to Bill Nye the science guy and leave the good programs to the rest of us.

End and summary of book tour; the universe with Ken Croswell.

I don't agree.

I don't agree with "jacob" and "Alex". Glad to see you are interested in the sciences, however Dr. Kaku is a hero within the scientific community for sharing his and other's views on popular science with the general public. There are also female guests from time to time and he has always encouraged more women to join the ranks. Rather than insult the man and his fans, why don't you just change the channel and listen to some young chick's show like Dr. Kiki's science hour if you can't stand this one. (No offense to Dr. Kiki) The man isn't even retirement age yet. Some day you will be as old if you can last that long and what are you going to do? Are you going to hide in a hole somewhere because of some rude 20 something who can't fathom anything beyond the next few days or relate to anyone more than 2 or 3 years older than themselves and thinks they know everything and you know nothing?

I agree. I love the show, but dr. Michio is becoming a bit boring and someone new (with more enjoyable voice) should replace him. I'm sorry to write this because I appreciate the work of profesor Kaku, but this is true.

Dear Mr. M.
You talk about the future - but you only talk about the future for the rich - with your medical breakthroughs and life in space. Get real ! What is your imediate Science for the poor and the meek. I guess you think you have paid your dues and now is your time to join the rich. Traitor to the people ! Off with your head!
