Kara was VERY helpful
Kara was very helpful, especially in suggesting we do a Zoom screen share, which made some problems I was having with navigation and document publishing much clearer. She should get a raise.

I needed to print out the forms for a passport. PDFiller was where I was sent to do this. Perfect! I am an 83 year old senior and using a filler is not going to be a part of my life.

Thank you for your service and helping me in canceling my account.Constance Heidt

What is Einstein's unified field theory?
Unified field theory, in particle physics, an attempt to describe all fundamental forces and the relationships between elementary particles in terms of a single theoretical framework. Then, in the early part of the 20th century, Albert Einstein developed general relativity, a field theory of gravitation.
What does unify field theory mean?
In physics, a unified field theory (FT) is a type of field theory that allows all that is usually thought of as fundamental forces and elementary particles to be written in terms of a pair of physical and virtual fields. Classically, however, a duality of the fields is combined into a single physical field.
What does unify theory mean?
A Grand Unified Theory (GUT) is a model in particle physics in which, at high energies, the three gauge interactions of the Standard Model that define the electromagnetic, weak, and strong interactions, or forces, are merged into a single force.
What is another name for the unified field theory?
In physics, a unified field theory (FT) is a type of field theory that allows all that is usually thought of as fundamental forces and elementary particles to be written in terms of a pair of physical and virtual fields.
What are the four main unified theory of electromagnetism?
FUNDAMENTAL FORCES All four of the known fundamental forces are mediated by fields, which in the Standard Model of particle physics result from exchange of gauge bosons. Specifically the four interactions to be unified are: Gravitation, Electromagnetism, Weak Interaction and Strong Interaction.
Who proposed grand unified theory?
This theory was given by Pakistani scientist Abdul Salem, who shared the Nobel Prize with Weinberg and Glasgow for it in 1979. This short article about physics can be made longer.
Who proposed unified field theory?
The first successful classical unified field theory was developed by James Clerk Maxwell. In 1820 Hans Christian Listed discovered that electric currents exerted forces on magnets, while in 1831, Michael Faraday made the observation that time-varying magnetic fields could induce electric currents.
Why do we need a grand unified theory?
So we need a unification of them. For this and various other things (like hoping to get a relation between many things that are separate for now, like the numerous physical constants). A Grand Unified Theory is a model in particle physics in which, at high energy, the three gauge interactions of the Stand.
