137 (one hundred [and] thirty-seven) is the natural number following 136 and preceding 138.

## In mathematics

137 is:

Using two radii to divide a circle according to the golden ratio yields sectors of approximately 137° (the golden angle) and 222°.
1/137 = 0.00729927007299270072992700..., its period value is palindromic and has only a period length of 8.

## In physics

• The fine structure constant, a dimensionless physical constant, is approximately 1/137, and the astronomer Arthur Eddington conjectured in 1929 that its reciprocal was in fact precisely the integer 137, which he claimed could be "obtained by pure deduction".[5] This conjecture was not widely adopted, and by the 1940s, the experimental values for the constant were clearly inconsistent with it (i.e. closer to 137.036).[6]
• Physicist Leon M. Lederman numbered his home near Fermilab 137 based on the significance of the number to those in his profession. Lederman expounded on the significance of the number in his book "The God Particle: If the Universe Is the Answer, What Is the Question?," noting that not only was it the inverse of the fine-structure constant, but was also related to the probability that an electron will emit or absorb a photon. He added that it also "contains the crux of electromagnetism (the electron), relativity (the velocity of light), and quantum theory (Planck's constant), it would be less unsettling if the relationship between all these important concepts turned out to be one or three or maybe a multiple of pi. But 137?” The number 137, according to Lederman, "shows up naked all over the place,” meaning that scientists on any planet in the universe using whatever units they have for charge or speed, and whatever their version of Planck’s constant may be, will all come up with 137, because it is a pure number. Lederman recalled that Richard Feynman had even suggested that all physicists put a sign in their offices with the number 137 to remind them of just how much they don’t know.[7]
• In the Bohr model, the innermost electron of an atom with Z = 137 would be orbiting (just below) the speed of light, and the next element (Z = 138) would be "impossible". Since the Bohr model does not include either quantum mechanics or special relativity, the fact that it breaks down in this regime is not surprising. However, such large atoms (if their nuclei were stable) could be expected to behave rather differently from a naive extrapolation of trends in the periodic table.
• Wolfgang Pauli, a pioneer of quantum physics, died in a hospital room numbered 137, a co-incidence that disturbed him.[8]

## In esoterism

• The fine structure constant of physics continues to convince esotericists that the universe has numerological fine tuning:[9] for example the age of the universe could be considered as roughly 13.7 times 1 billion years, though newer estimates put this value at 13.8.[10][11]
• The Hebrew word קבלה (Kabbalah) has a Gematria (numerical value) of 137. In Modern Hebrew, the root of Kabbalah (ק-ב-ל) can mean either "receiving" or "parallel." Kabbalah is generally taken to mean "the received tradition," which conveys the continuity of a tradition that has been passed down from generation to generation.[12] Nevertheless, the earlier nuance of meaning is seen in the first appearances of its root in the Torah (Exodus 26:5 and 36:12), where it means “parallel” or “corresponding” rather than “receiving.” It is used to describe the “corresponding loops” which, when clasped together, enjoined the two sections of the Tabernacle’s ceiling. These loops were suspended directly over the veil that divided the Holy Place and the Holy of Holies. Symbolically, this is the threshold between the physical dimension and the utterly spiritual dimension; in other words, at the boundary line of the physical world, the number 137 emerges. The wisdom of Kabbalah is to find correspondences between the mundane and spiritual levels of reality.[13]

## In religion

• The Bible says that Ishmael,[14] Levi[15] and Amram[16] all lived to be 137 years old. The three appearances make it the most common lifespan of individuals in the Bible.
• According to the verse in Genesis (17:17) there was a ten-year age gap between Abraham and Sarah. Sarah died at the age of 127 (Genesis 23:1), thus Abraham was 137 years old at her death. According to Rashi's commentary on Genesis 23:2, Sarah died when she heard that Isaac had almost been sacrificed, thus Abraham was 137 years old at the Binding of Isaac.
