What particles did scientists discover in 1968?
Quarks were officially discovered at the Stanford Linear Accelerator Center in 1968. However, they had been the topic of theoretical models since 1964.
How big was the particle that started the big bang?
It isn't by any means clear that there was anything that "started the Big Bang" or that there even was a point in time where it started. In any case, no hypothetical or theoretical model has it starting with "a particle". Although there is general agreement among cosmologists on the timeline of the Big Bang once it got started, there are competing models about the conditions of the actual starting point, if any. Some relativistic models have it starting with a singularity, a geometric point of zero dimensions, zero volume. Other models have it starting as a non-zero volume area of spacetime - but still much smaller than, for instance, a proton.
How do scientists calculate future climate changes predictions?
Scientists use complex computer models known as climate models to calculate future climate change predictions. These climate models simulate the Earth's climate system by incorporating data on greenhouse gas emissions, land use changes, and other factors that influence climate. By running these models with different scenarios and assumptions, scientists can predict how these changes will affect global temperature, precipitation patterns, sea level rise, and other climate variables in the future.
When can models be used to collect data and make predictions?
when models chave been validated with evidence
Creating representations of complex object or processes?
models are the answer

Difference between Applied Economics and Theoretical Economics?
Economics is concerned with the allocation of scarce resources. This general definition can be applied across a variety of applications including labor economics, financial economics (finance), macroeconomics, microeconomics, etc. For each of these areas, theoretical models are built (by theoreticians) and these models are tested (by applied economists). When they are built, they are built on the basis of how a simplied world should work under certain assumptions. For example, under the assumptions that people have unlimited wants, get satisfaction from consumption of resources, consumption of the first unit brings more satisfaction than consumption of the next unit, and a certain income and prices of goods, theoretical economics will predict that consumers will but some of each good. This is a theoretical model because it is completely created in the mind and shows what will happen if all the assumptions are correct. The models are usually mathematical in nature and, although they may look complex to the outside observer, are usually very simple abstractions from reality. Applied economics is the testing these theoretical models on real world data to see if the theoretical relationships are shown to exist in reality. One reason the theoretical model will not test well in reality is if the theoretician forgot an important assumption. Applied economics basically tests theoretical economics. The tests usually involve taking the theoretical models and creating statistical models from them. Theoreticians usually only work with math. Applied economics that test theoretical models usually work with statistical theory. There is also a middle ground of applied economists that use already verified theoretical models and apply real world data to it to measure some economic phenomena of interest. Fundamentally, there is no reason that economics should be so heavily math and statistics based. Since the 50 or so years since the mathematization of economics there has been no more important discoveries made than the previous non-math years of the examination of the political economy.
What do you call broad theoretical models of the social or natural world?
broad theoretical models of the social or natural world
What is theoretical classification?
Theoretical classification is a way of grouping objects or concepts based on their similarities and differences, often using theoretical principles or models. It helps in organizing information and understanding relationships among different elements within a defined framework.

What is a quantum field?
The quantum field theory is a theoretical framework for constructing quantum mechanical models. These models are of subatomic particles in particle physics.
Joyce travelbee human to human relationship?
The conceptual and theoretical nursing models help to provide knowledge to improve practice, guide research and curriculum and identify the goals of nursing practice. The state of art and science of nursing theory is one of continuing growth. Using the internet the nurses of the world can share ideas and knowledge, carrying on the work begun by nursing theorists and continue the growth and development of new nursing knowledge. It is important the nursing knowledge is learnt, used, and applied in the theory based practice for the profession and the continued development of nursing and academic discipline.
Short meaning of theoretical physics?
Theoretical physics is a branch of physics that employs the use of abstractions and mathematical models of systems and physical objects to explain natural phenomena.
What is theoretical physicists?
Theoretical physicists employ mathematical models and abstractions of physics in an attempt to explain experimental data taken of the natural world without actually performing experiments.

What is the similarity between computer models and physical models?
They are both models, andthey both can be explained.
