WebThis discovery made the development of the atomic bomb feasible and cemented Fermi's position as the father of the atomic age. He would later join the Manhattan project to work on the atomic bomb but return to primarily to teaching and research after the second world war. [1] He passed away in 1954 due to stomach cancer.

WebThe application of this procedure to the calculation of the Fermi age of H/sub 2/O leads to a value of T = 25.0 cm/sup 2/, which is in very good agreement with the theoretical value of T = 25.3 cm/sup 2/ obtained again and again by other methods. The analysis of the assumptions made in this calculation shows that the above value might be very low.
