The Los Alamos Primer: The First Lectures on How To Build an Atomic Bomb
The classified lectures that galvanized the Manhattan Project scientists―with annotations for the nonspecialist reader and an introduction by a Pulitzer Prize-winning historian.
In March 1943 a group of young scientists, sequestered on a mesa near Santa Fe, attended a crash course in the new atomic physics. The lecturer was Robert Serber, J. Robert Oppenheimer's protégé, and they learned that their job was to invent the world's first atomic bomb.
Serber's lecture notes, nicknamed the "Los Alamos Primer," were mimeographed and passed from hand to hand, remaining classified for many years. They are published here for the first time, and now contemporary readers can see just how much was known and how terrifyingly much was unknown when the Manhattan Project began. Could this "gadget," based on the newly discovered principles of nuclear fission, really be designed and built? Could it be small enough and light enough for an airplane to carry? If it could be built, could it be controlled?
Working with Richard Rhodes, Pulitzer Prize-winning historian of the development of the atomic bomb, Professor Serber has annotated original lecture notes with explanations of the physics terms for the nonspecialist. His preface, an informal memoir, vividly conveys the mingled excitement, uncertainty, and intensity felt by the Manhattan Project scientists. Rhodes's introduction provides a brief history of the development of atomic physics up to the day that Serber stood before his blackboard at Los Alamos. In this edition, The Los Alamos Primer finally emerges from the archives to give a new understanding of the very beginning of nuclear weapons. No seminar anywhere has had greater historical consequences.

I was reading Richard Rhodes book on the building of the atom bomb, and they listed this as a reference.
It's like nuclear physics for dummies...provided the dummies are all PhDs.

A very interesting read, but perhaps mainly for physicists.
Richard Rhodes' introduction is what you would expect - a summary of the relevant sections of his classic book "The Making of the Atomic Bomb".
Serber's preface is the most compelling part of the volume - the physics not too heavy for a non-physicist and full of interesting autobiographical details. The photos are also interesting - some may be familiar from other books but most were new to me.
The primer itself is presented in a series of snippets in between more up-to-date explanations by Serber. The explanations don't really hit the mark - some are very elementary (eg. explaining basic aspects of scientific notation) and the rest are mainly too advanced for anyone without a physics degree. Nevertheless, the primer did give me some kind of understanding for the types of work that the theoreticians performed at Los Alamos.
As a historical document, this book is fascinating (enhanced further by the inclusion of 2 Frisch-Peierls memos), so it's well worth reading even for a non-physicist, but don't expect to come away with more than a flavour of the sorts of problems they had to solve.

post-oppenheimer interest read. i don’t know nearly enough physics to grasp some concepts in this properly, but i found it informative regardless.

It seems silly to give a star rating to something like this. I'd describe it as a historical document that outlines lectures that Robert Serber gave to newcomers at Los Alamos as the atomic bomb was being developed. He gave the lectures "to draw a starting line on the work we had to do."
Of course it's a grim subject, knowing what we know now about how their success changed the world.
The lectures are interesting; a snapshot of what we knew - and didn't know - in 1943. But as interesting as the lectures are Serber's notes interspersed throughout. Like this bit from his Preface, talking about the famous question of whether a nuclear explosion would ignite the atmosphere:
And here in the notes before the presentation of the first lecture:
The lectures make me want to brush up on the math I once knew.
A powerful piece of history.

Edward brought up the notorious question of igniting the atmosphere. Bethe went off in his usual way, put in the numbers, and showed that it couldn’t happen. It was a question that had to be answered, but it never was anything, it was a question only for a few hours. Oppy made the big mistake of mentioning it on the telephone in a conversation with Arthur Compton. Compton didn’t have enough sense to shut up about it. It somehow got into a document that went to Washington. So every once in a while after that, someone happened to notice it, and then back down the ladder came the question, and the thing never was laid to rest.
And here in the notes before the presentation of the first lecture:
There was hammering in the background, carpenters and electricians working out of sight but all over the place. At one point during the lectures a leg came bursting through the beaverboard ceiling. One of the workmen misstepped and they had to pull him out.
The lectures make me want to brush up on the math I once knew.
A powerful piece of history.

This book contains the elements of the primer lecture series that was given at the start of the Manhattan Project in Los Alamos by Robert Serber. It provides a state of the physics around 1942 which was used to build a fast neutron chain reaction atomic bomb. It is rather rather technical and the annotations help a lot to understand the basic physics. The first aha moment in this book was the realization that all theoretical physics to make the bomb were known when Los Alamos opened. The neutron economy in the models was sorted out: the role of the tamper, nucleosynthesis and energy book keeping. What was missing were practical measurements to feed the models, such as cross sections of neutron collisions and the metallurgical aspects of 235U and 239Pu (because these metals did not existed in reasonable quantities yet), and the engineering of the gadget itself. The second aha for me what that he explosives are not required to "ignite" the atomic bomb. They are merely required to achieve a critical mass that is contained enough to have 80 generations of neutron fission happening. For me, the insights and historical context were very interesting, therefore 4 stars. If you are not beyond the movie Oppenheimer, this is not yet for you.

The Los Alamos Primer is a fascinating dive into the scientific and historical heart of the Manhattan Project, and I thoroughly enjoyed it, giving it a well-deserved 5/5 stars. This book, based on the original lectures delivered by physicist Robert Serber at Los Alamos, strikes a unique balance: it’s dense with technical detail yet surprisingly accessible for a non-scientist like me.
The structure is particularly engaging, blending excerpts from the original primer with Serber’s contextual commentary, which provides invaluable background on the science and the era. While the math and physics occasionally went over my head, the clarity of the writing and the author’s ability to break down complex ideas kept me hooked and taught me a ton. The prologues, introductions, and appendices are standout features, adding unique insights and historical depth that enrich the experience.
I’d highly recommend it to anyone interested in science, math, history, or military topics. It’s a brilliant blend of technical rigor and historical narrative that both educates and captivates.

This is a nice introduction to exactly what it says. The comments by Serber are especially nice as they point out errors, and give some nice history tidbits. This is a short but interesting read, and covers a lot of basic ideas (and touching on the the not so basic ideas) that are crucial for understanding atomic weapons. I do rather wish they could add in SI units for calculations, but as a historic document it retains cgs units. Also the "l" for mean free path and the "1" for the number one are nearly indistinguishable in some of the text. Using an ℓ instead of "l" would have been much easier to read. These are rather minor complaints, though, as this book is a short and informative read.

Book 19 of 2025: The Los Alamos Primer by Robert Serber with forward ny Richard Rhodes (1992, University of California Press, 176 p.)
This is an annotated version of the 5 lectures given to Los Alamos staff in 1943 on "how to build an atomic bomb".
It is an interesting historical and scientific document, dealing with the theory of the super bomb (not to be corroded with Edward Teller's Super hydrogen fusion homb).
Richard Rhodes, author of rhe supurb history, The Making of the Atomic Bomb, contributed a forward that provides historical context.
Despite the equations, it was pretty undesirable to this non-phyicist.
When I eventually visit the Trinity Site in NM, I will bring my bound copy with me.

Very interesting and I understood more of it now than the decade earlier I first discovered it! The end notes on what a nuclear bomb could potentially do was quite alarming in hindsight as they grossly underrated the drastic effect of using such a weapon would have

I was not expecting a "real book", but a somewhat annotated set of lecture notes.
What I found: dumbed down explanation and technical details with no way of telling what was originally part of the lectures, and what is "authentic".

Clean and concise, but everything here is now really common knowledge.

I found this to be a fascinating read, just as I find most things related to the Manhattan Project, but I dock a star for how challenging it can be for those (like me) uninitiated in physics and theoretics. In any case, it's a passenger seat view of the white-knuckle ride J. Robert Oppenheimer and Co. took, from the inception of a chain reaction, all the way to the world's first nuclear explosion, and beyond. Hold on tight.

Good, but expectedly terse lecture conspect.
Some of concepts and theories described do require an advanced knowledge of physics and mathematics, however the main ideas and topics are still accessible for anyone reasonably versed in basics. The original primer's text interspersed with author's comments provides for a reasonable, discussion-like literary delivery style.

interesting historical document, but the wildest thing about it hat we learn all of this stuff in grade 10 science and less than a hundred years ago, all of it was phd-level discoveries like "you don't learn anything new" yeah man welcome to The Progression Of Time

A bit dense of a read for me. Would probably be for insightful if I had a better understanding of physics. The introductions were great though and did pick up a few tidbits here and there.
Regardless, a neat piece of history.

I thought it was going to be an actual textbook, but it is more of a history of the founding of Los Alamos. An interesting period in time.

Great coffee table and office desk book! Keep them guessing. Lol
Main point is the realization this was before calculators!
