The final section of the book, 7. AN ELEMENTARY DERIVATION OF THE EQUIVALENCE OF MASS AND ENERGY, from pages 70 to 73, claims to use the law of conservation of momentum, an expression for the pressure of radiation, and two coordinate systems, one of which is moving rapidly along the direction of the axis of a system which is fixed relative to a body that has equal radiation hitting it from both sides. I doubt if the professor for the Physics class expected me to think of this method of finding that E = mc-squared, and I'm still not sure that I believe this approach proves it. In the still system, the momentums of equal and opposite radiation complexes cancel each other completely, so the amount of energy which might be involved doesn't matter. For the system which is moving, the radiation is assumed to be hitting the body from some angle related to that speed, and the change of momentum added by the component along the axis of motion does not change the speed, so the additional momentum is considered an addition to the mass of the body. The mathematical solution depends on solving equations for the difference in the mass observed for using two different systems, one of which is observing zero momentum, and the other thinking, "We anticipate here the possibility that the mass increased with the absorption of the energy E (this is necessary so that the final result of our consideration be consistent)." I believe Albert Einstein wrote this book, but I still wonder what it is telling us.

I loved the way Billy found the courage to face his fears and conquer the challenge of interviewing a genius like Albert Einstein. I liked that it shows that it's okay to daydream, to think about life in a different way than the people around us think, and that if you face your fears, you can accomplish many things in life. There will always be people who feel that because someone thinks "outside of the box" or appears absent-minded, something is wrong with us.
I loved the childlike style of Billy's four questions and that the answers were actually in Einstein's own words. And I thought it was a good lesson to show that Billy was able to do further research and write another story on his own once Albert Einstein 'opened the door' to Billy's quest for knowledge.
This story will teach my granddaughter that our imagination is what makes us unique, that once you take the first step and just do your very best, you can accomplish great things, in spite of your fears.
On a personal level, I think I related to this story because as a child, I always felt "different" and didn't look at things in the same way as other kids did. I was a daydreamer, couldn't concentrate in school and often got into trouble because my mind wandered.
I wish I had been able to read this book when I was young - I'm sure it would have made me feel that it was okay to look at things differently, to ask questions, to always be curious. (I'm a cookbook author today, so I guess I succeeded in spite of myself!)
Thanks to the author for a wonderful book! I also loved the illustrations and the way they were integrated into the story. They remind me of Norman Rockwell's artistic style. Well done!

I thought this book shared some fascinating facts about Einstein's life in a cute and unintimidating way - a fictional character's (a cub reporter with the Princeton Elementary School News) interview with Albert Einstein. At the end of the interview the young reporter asks Albert four more questions. My favorite, and I hope the author doesn't mind me sharing this one, is "What makes you think up all those great ideas?" I loved Einstein's answer - "I use my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world". There are several great quotes from Einstein in the book.
I bought this book for two of my 8 year old nephews. I hope they will have as much fun reading it as I did and will be encouraged to let their imaginations fly and take them to all sorts of interesting thoughts and places.
Billy, a shy young reporter for the school newspaper goes to interview Einstein to find out what he was like as a child. To his surprise, the great genius had lots of problems when he was a boy. Any child who has ever felt shy, inadequate or less than a star will relate to the young Einstein, who was late to talk, not a star in school, and subject to bursts of bad temper.
Wishinsky's style invites the reader to explore Einstein's world in a variety of interesting ways. These include the text of his final report on Einstein "When he Grew Up," a timeline of the important dates in his life and an excerpt from Billy's notebook, with answers in Einstein's actual words. For example, to the question "Why don't you wear socks?'", Einstein asnwers "When I was young I found out that the big toe always ends up making a hole in the sock. So I stopped wearing socks."
Children will find the man and the story irresistable. Told in clear, engaging prose and dialogue, WHAT'S THE MATTER WITH ALBERT EINSTEIN? will delight all young readers. Jaques Lamontagne's illustrations of Einstein at different periods of his life will round out the familiar image of the frizzy-haired genius.
Frieda Wishinsky has added to the long list of books about Albert Einstein one that truly makes him accessible, and that will be treasured by children of all ages.
One might question why you might purchase a book such as this. Well the answer is quite simple. Logic. Now when I say logic I don't mean the logic of the words themselves rather the logic that you might read such an impressive work.
Einstien was a genius in his time, a genius yet to be surpassed (in the authority of Science that is). His works are timeless, classic examples of the scientific process and this particular is a well-balanced example.
Written during the years of the 1910s this volume's works depict a dedication to science even through the war in Europe.
A Must Read!
Justin Smith
of Albert Einstein as an absentminded, head-in-the-clouds-genius.
Though Einstein is arguably the most widely covered, continuing
science story in history and is most noted for his scientific
theories that transformed our view of the universe. This book
chronicles the life of an Einstein that the masses knew nothing
about. An Einstein described as a troublemaker, an agitator, a
fervent pacifist, a socialist, and an open critic of racism.
Einstein arrived in the United States in 1933, the year of
the Nazi's ascent to power in Germany, and became the focus of
J. Edgar Hoover's FBI. And by any means necessary the FBI amassed
a 'file cabinet' of information on him. Fred Jerome stumbled on
documents that addressed Einstein as a Spy and a Kidnap Plotter.
And a dossier where Jerome discovered the political dimension of
Albert Einstein's life and his intense commitment to social justice.
Jerome says when he realized how much had not been told to us about
the life of the 'Man of the Century', he felt as though he had been
robbed. This is not another biography of Einstein, some two hundred
have already been written. It is a window opened by the FBI on the
nature of Einstein's politics, the depth of his public involvement,
and the generosity of his endorsements of organizations he supported.
And it is this activism that made Hoover's Bureau consider Einstein
dangerous. This book reveals information that makes one think the
history we know is sanitized, and what we don't know is at times
appalling. It talks of a 'list' maintained by the FBI on celebrities,
political figures and anyone thought to have affiliatiions with the
Communist Party. It underscores the dangers that can arise, and the
rule of law that exists in times of obsession with national security.
And it creates questions on where the line should be drawn on the issue
of an invasion of privacy. This one will make you take a seat.

At this point, I will say that my understanding stands at a finite point in which it would be only arrogant for me to claim I understood the entirety of the book. Nonetheless, I found this book completely readable, mostly due to the fact that there are no formulas to follow. My knowledge of relativity is limited and I have given you what I believe I understand. Its a short book with the writing clear and concise and logical; which surprised me hearing stories about Einsteins genius in which he is unable to explain in laymans terms. Highly reccomended!
