Standard ModelThe Standard Model is the most comprehensive theory of particle physics. It describes all known particles in the universe and all forces governing their interactions, except gravity. It was developed by identifying the indivisible building blocks that make up the zoo of particles observed in cosmic ray showers and particle accelerator collisions. These include quarks, which combine to form more massive particles like the proton, and standalone particles called leptons, including the electron. All leptons and quarks also have antimatter versions. The electromagnetic, weak nuclear, and strong nuclear forces are each transmitted by particles—gauge bosons—that are exchanged between quarks and leptons to exert these forces. Most observed phenomena involving electromagnetism, radioactive decay, and nuclear physics result from these exchanges. However, particle mass results from quarks, leptons, and gauge bosons uniquely interacting with the Higgs boson. The Standard Model provides no explanation for dark matter or dark energy. Future development of a theory of quantum gravity to model gravitons—the gauge bosons of the gravitational force—may lead to a theory of everything to replace the Standard Model.

The Top 5 Problems of the Standard Model SciShow The graviton may be the last missing piece of the Standard ModelWhile the electromagnetic, strong nuclear, and weak nuclear forces can be explained through interactions with particles, gravity is instead best modeled through spacetime curvature. Discovering a quantum particle of gravity would unite the two pillars of modern physics—quantum mechanics and general relativity—toward developing a theory of everything. PBS Space Time Italian physicist Enrico Fermi (1901–1954) on the Standard Model"If I could remember the name of all these particles, I'd be a botanist." BrainyQuote View an infographic of the Standard ModelMuch like this visualization, the theory serves to catalog almost all phenomena involving visible matter comprehensively, including organizing observed elementary particles by shared characteristics and explaining most fundamental forces and quantum properties. Florian Winklet Measurements of an electron’s magnetic moment help test the Standard ModelA particle’s magnetic moment quantifies how it responds to the presence of an external magnetic field. An electron’s value can be measured down to 14 decimal places, with certainties in the first 12 allowing it to be used to assess the accuracy of predictive models. Wired View a breakdown of the mathematics behind the Standard ModelThe Lagrangian version of the theory—related to the system's energy—presents a vast mathematical equation, with different components representing various force interactions and types of particles, including ghost particles to cancel out mathematical redundancies. Symmetry Magazine The Standard Model predicts massless particles we have observed to have massNeutrinos—elusive cousins of the electron that rarely interact with other matter—have been observed to transform into one another, which can only occur if they have mass. The theory also cannot explain why the universe has much more antimatter than normal matter.

Nautilus The standard measurement for precious metals comes from a small town in France The troy ounce is the standard measurement for precious metals like gold and silver and it’s heavier than a standard ounce. The term “troy” is widely believed to come from the town of Troyes in France, which was a popular trading hub for merchants all across Europe in the Middle Ages. Investopedia Airbus is a rare European industrial success story who overtook a rival American firmAfter World War II, the US dominated aviation, particularly Boeing. To compete, Europe's major industrial nations pooled resources to form Airbus, a customer-centric airplane manufacturer. Its A320 family of planes became the most popular in airliner history, leading to profitability in the 1990s. Amid Boeing's major hurdles in recent years, Airbus remains the industry leader. Works in Progress By 2030, experts estimate a 1 in 1000 chance of a plane being hit by space debrisAs more satellites and spacecraft are launched, the rate of space debris re-entering Earth's atmosphere, including those that do not burn up completely, increases. International space agencies and air traffic control systems will need to coordinate to develop standardized methods and technical solutions to prevent and minimize future crisis scenarios. Space.com 'Jolene' was based on a real woman who flirted with her husbandThe song was Dolly Parton’s second No. 1 hit and a modern standard that’s been covered by the likes of the White Stripes and Beyoncé. According to Parton, it was based on a real-life experience about an attractive bank teller who flirted with her husband. That woman’s name wasn’t actually Jolene, though: That was the name of a young fan who’d once asked Parton for an autograph. NPR The 1910 Wright Model B was the brother’s most successful aircraftThe model, built from 1910 to 1914, was the first designed to be constructed in bulk, with four built each month in 1911 and 1912. The two-seater was used in exhibition flights and training for some of the earliest uses of airplanes in military contexts. Field of Firsts Arguments for returning to a gold standard reappear from time to timeHowever, critics argue that globalization has made the gold standard impractical for modern economies, as it limits a nation’s ability to have a flexible monetary policy—hence, none of today's governments have a gold standard. The Conversation Craig Claiborne invented the modern food criticThe New York Times critic began his column "Directory to Dining" in 1962. While there had been restaurant reviews before then, Claiborne's ethical standards and appreciation for a variety of cuisines established a new kind of food critic and, in the process, a new kind of eater.
