A Quote by Steven Weinberg

My work during the 1970s has been mainly concerned with the implications of the unified theory of weak and electromagnetic interactions, with the development of the related theory of strong interactions known as quantum chromodynamics, and with steps toward the unification of all interactions.
In 1956, when I began doing theoretical physics, the study of elementary particles was like a patchwork quilt. Electrodynamics, weak interactions, and strong interactions were clearly separate disciplines, separately taught and separately studied. There was no coherent theory that described them all.
Gravitational and electromagnetic interactions are long-range interactions, meaning they act on objects no matter how far they are separated from each other.
My Ph.D. thesis, with Sam Treiman as adviser, was on the application of renormalization theory to the effects of strong interactions in weak interaction processes.
The strongest interactions are the nuclear interactions, which include the forces that bind nuclei together and the interaction between the nuclei and the z mesons. It also includes the interactions that give rise to the observed strange-particle production.
Cities are just a physical manifestation of your interactions, our interactions, and the clustering and grouping of individuals.
My interactions with musicians have been simply that: interactions with musicians. Issues of gender, or anything else beyond the music-making, have in my experience played no role in whether or not a musician has been able to articulate my intentions as a composer.
What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.
In terms of the most unique thing we do socially, my vote goes to something we invented alongside cities - we have lots of anonymous interactions and interactions with strangers. That has shaped us enormously.
The revolution which began with the creation of quantum theory and relativity theory can only be finished with their unification into a single theory that can give us a single, comprehensive picture of nature.
In a world where your interactions with humans are solely about rating one to five, two things happen: One is all humanity is lost in the name of fake pleasantries and also there's no nuance to that system. There's no room for complex interactions that are rich and meaningful.
Sci-fi fans are awesome. They're very smart, they like to be involved, they like to ask questions. I've been asked questions I don't even know the answer to. I've never had any aggressive interactions. I've had lovely interactions.
It's nice to be able to look at one protein, but life is driven by the interactions between proteins, so it's really essential to be able to see multiple proteins at a time to understand these interactions.
Everything we know about the universe is studied by using telescopes or other instruments that look at visible light, infrared, ultraviolet or X-ray - different wavelengths of electromagnetic interactions. Only 4 percent of what's in the universe gives off electromagnetic radiation, so we don't have any handle on the rest.
We're going to need a definitive quantum theory of gravity, which is part of a grand unified theory - it's the main missing piece.
Whereas children can learn from their interactions with their parents how to get along in one sort of social hierarchy--that of the family--it is from their interactions with peers that they can best learn how to survive among equals in a wide range of social situations.
Physicists are interested in measuring neutrino properties because they tell us about the structure of the Standard Model, the well-tested theory that describes matter's most basic elements and interactions.
