Oppenheimer and Weisskopf suggested that this was a result of <a href="/wiki/Quantum_fluctuation" title="Quantum fluctuation">quantum fluctuations</a> of the electromagnetic field, which gave the electron more energy. According to pre-war <a href="/wiki/Quantum_electrodynamics" title="Quantum electrodynamics">quantum electrodynamics</a> (QED), the energy of the electron consisted of the bare energy it had when uncoupled from an electromagnetic field, and the self-energy resulting from the electromagnetic coupling, but both were unobservable, since the electromagnetic field cannot be switched off. QED gave infinite values for the self-energies; but the Lamb shift showed that they were both real and finite. <a href="/wiki/Hans_Kramers" title="Hans Kramers">Hans Kramers</a> proposed <a href="/wiki/Renormalization" title="Renormalization">renormalization</a> as a solution, but no one knew how to do the calculation.<sup id="cite_ref-FOOTNOTEBrownLee2006157–158_98-1" class="reference"><a href="#cite_note-FOOTNOTEBrownLee2006157–158-98"><span class="cite-bracket">[</span>97<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-Bethe_1947_8-1" class="reference"><a href="#cite_note-Bethe_1947-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> </p><p>Bethe managed to perform the calculation on the train from New York to <a href="/wiki/Schenectady" class="mw-redirect" title="Schenectady">Schenectady</a>, where he was working for <a href="/wiki/General_Electric" title="General Electric">General Electric</a>. He did so by realising that it was a non-relativistic process, which greatly simplified the calculation. The bare energy was easily removed as it was already included in the observed mass of the electron. The self energy term now increased logarithmically instead of linearly, making it mathematically convergent. Bethe arrived at a value for the Lamb shift of 1040 MHz, extremely close to that obtained experimentally by Lamb and Retherford. His paper, published in the <i>Physical Review</i> in August 1947, was only three pages long and contained just twelve mathematical equations, but was enormously influential. It had been presumed that the infinities indicated that QED was fundamentally flawed, and that a new, radical theory was required; Bethe demonstrated that this was not necessary.<sup id="cite_ref-Bethe_1947_8-2" class="reference"><a href="#cite_note-Bethe_1947-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-FOOTNOTEBrownLee2006158–159_100-0" class="reference"><a href="#cite_note-FOOTNOTEBrownLee2006158–159-100"><span class="cite-bracket">[</span>99<span class="cite-bracket">]</span></a></sup> </p><p>His calculation of the Lamb shift has been called "the most important discovery in the history of the theory of quantum electrodynamics" by the physicist <a href="/wiki/Richard_Feynman" title="Richard Feynman">Richard Feynman</a>, while physicist Paul Dirac called it "the most important calculation in physics for decades".<sup id="cite_ref-:0_10-1" class="reference"><a href="#cite_note-:0-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> </p><p>One of Bethe's most famous papers is one he never wrote: the 1948 <a href="/wiki/Alpher%E2%80%93Bethe%E2%80%93Gamow_paper" title="Alpher–Bethe–Gamow paper">Alpher–Bethe–Gamow paper</a>.<sup id="cite_ref-101" class="reference"><a href="#cite_note-101"><span class="cite-bracket">[</span>100<span class="cite-bracket">]</span></a></sup> <a href="/wiki/George_Gamow" title="George Gamow">George Gamow</a> added Bethe's name (in absentia) without consulting him, knowing that Bethe would not mind, and against <a href="/wiki/Ralph_Alpher" title="Ralph Alpher">Ralph Alpher</a>'s wishes.

I was taught to pray in the evening before going to bed, and I attended the Protestant religious instruction, which was given in the schools in Germany. I was also confirmed, and the instruction which I got in this connection got religion out of my system completely.
