Feynman scattering necklace | sterling silver
Ask a physicist how particles interact and she will probably pick up a pen and draw a Feynman diagram. This Feynman scattering necklace is for the women who think that way, whether you are one of them or you love one.
Who It's For
- a fiancée or partner with a love of all things physics
- a friend who shares your love of physics
- a daughter finishing a physics degree or a PhD in particle physics
- yourself, for graduation or to wear every day
Jonny F.: “Bought this for my fiancée who has a love of all things Physics and an acute adoration for Feynman. She was delighted.” Martina B., who bought it for herself: “A gift from me to me for Christmas. Unbelievable. It's so cute and well done. Will use it for my graduation.”
How a Feynman Diagram Works
A Feynman diagram is shorthand for a calculation. Straight lines stand for particles such as electrons, wavy lines for photons, and each point where lines meet is an interaction. Every diagram turns, by fixed rules, into a precise mathematical term, and from their sum comes the chance that particles scatter in a given way. In quantum electrodynamics, each extra pair of meeting points brings in another factor of the fine-structure constant, about 1/137, so a few simple diagrams already come close to the answer. Precision takes many more. For the tenth-order term in the electron's magnetic moment, Toichiro Kinoshita and his colleagues worked through 12,672 diagrams.

FAQ
How big is the pendant, and how does it sit?
The pendant measures 34 mm (about 1.3 inches) from end to end, about a third wider than a 2-euro coin. The chain attaches at both ends, so it sits across the chest just below the collarbone. It comes on a 45 cm (17.7 inch) sterling silver chain with a 5 cm (2 inch) extender, and extra chains of 40, 42, 45 or 50 cm with extender, or 80 cm, are sold on this page. Our sterling silver is nickel-free. Silver can darken over time, and the cleaning cloth that comes with it brings the shine back.
Is there a gold version?
Yes. The same 34 mm pendant also comes in 18K gold vermeil (2.5 microns of 18K gold over sterling silver), on a 45 cm gold vermeil chain with a 5 cm extender. Choose the finish the recipient already wears. The design is the same in silver and gold vermeil.
Will it arrive in time, and what if it isn't right?
It ships free worldwide with DHL Express and arrives in 1-5 business days. We pay the import duties and taxes, so there is nothing to pay on delivery. It comes in a ready-to-gift jewelry box and festive envelope. If it isn't right, our 30-day “Love It or Return It” policy applies.
Did Feynman really paint his diagrams on a van?
Yes. In 1975 Richard Feynman and his wife, Gweneth, bought a Dodge Tradesman Maxivan and had it painted with Feynman diagrams. QED and QUARK were already taken as number plates, so he settled for QANTUM. One day a motorist at a red light asked the woman at the wheel why she was driving a van covered in Feynman diagrams. It was Gweneth, and she answered: “Because my name is Gweneth Feynman.”
