On the evening of August 11, 1945, the blueprint of the Manhattan Project was smuggled to Russian intelligence, concealed within a packet of cigarettes. How could such vast information be hidden in a cigarette pack, and who could be the smuggler? Chaos ensued in the White House meeting.
D. Oppenheimer listed the names of 12 scientists who were associated with the Manhattan Project and possessed the capability for such an operation. The hunt for the traitor begins. Who could be this saboteur?

In the annals of human civilization, never before has espionage played such a colossal role. The stolen blueprint in question is that of the atomic bomb. To fathom this further, we first need to understand the very nature of an atomic bomb.
At first, it was claimed that an atomic bomb was uncomplicated. Later, it was disclosed that within an atomic bomb, three distinct elements exist. Join us in this episode as we delve deeper into this subject.

In this universe, there are substances or elements that gradually emit energy, transforming from one element to another. For instance, from uranium to radium, from radium to radon, and finally, from lead to a halt. In 1919, the scientist Rutherford sought to understand all of this. Experiments commenced.
It was during this time that scientist Einstein put forward a formula, which is E=mc2. Alongside him, a Bengali scientist, Satyendra Nath Bose, published a numerical analysis, which was later recognised by Einstein, and it became known as the 'Bose-Einstein statistics.' Today, it is more commonly referred to as 'Bose statistics.'

At that time, research on nuclear physics was taking place in three places on Earth: Cambridge, Copenhagen, and Göttingen. Among these, Göttingen was prominent. It was here that astronomers were conducting their studies. Who was there? Whose words were they heeding?
In the small German city of Göttingen, a myriad of strange and remarkable events were unfolding. We will discover these events in this episode.

Before, electrons and protons were already discovered within the atom. Now, in 1932, scientist Chadwick uncovered the 'neutron' residing within the atom. The very essence of the atom underwent a complete transformation. The scientific community was in awe, and we advanced to the second stage of nuclear bomb development.

While researching boron, the Curie couple observed a faint glow and extracted a small amount of energy from it. This marked the third phase of nuclear bomb development. However, this concept troubled scientist Joliot-Curie. He believed it was a tremendous power that needed to be kept secret. He attempted to conceal it but, in the end, was unsuccessful.
Much later, after escaping from Germany, scientist Joliot-Curie became involved with the Manhattan Project, becoming a key figure in the development of the atomic bomb.

It's called the 'Pope of Physics,' says the scientist Enrico Fermi from Italy. Through his research, he proved capable of splitting the uranium atom. There, he observed artificial radioactivity occurring and new elements being born. Later, it became evident that he hadn't produced any new elements. This marks the fourth step towards creating the atomic bomb.
At this time, Madame Curie's daughter, Irène Curie, made an appearance on the stage. She claimed to have shattered the nucleus of uranium with electroneutral neutrons in her laboratory. The scientific community did not readily believe her, and Otto Hahn, the father of German science, became deeply agitated. He penned a stern personal letter.

Even after receiving Otto Hahn's letter, the Curie couple did not abandon their experiments. They continued to investigate and published an article in a scientific journal. There, they revealed that by bombarding the nucleus of uranium, they had discovered a new element called 'lanthanum.' Scientist Otto Hahn decided to test it himself. He entered the laboratory to verify what they had claimed.
After three weeks, he emerged from the laboratory. The Curie couple's experiments had indeed been flawed, and he rectified their mistakes. Hence, it is said that scientist Otto Hahn was the first to successfully split the nucleus of uranium. This marks the fifth step on the path to creating the atomic bomb.
