In this chapter we are interested in how undergraduate physics students in three countries experience the equations they meet in their education. We asked over 350 students in the USA, Australia and Sweden the same simple question: How do you know when you understand a physics equation? Students...

What does "double less than" mean in physics?Physics:The subcategory of science that deals with matter, energy, and the behavior of the materials is known as physics. It includes the study of topics of heat, electricity, magnetism, optics, nuclear science, and mechanics....
By this I don't mean a pessimistic dissatisfaction of the world – we don’t like the way things are –I mean a constructive dissatisfaction.The idea could be expressed in the words, “This is OK, but I think things could be done better. I think there is a neater way to do this. ...
This would be fine if the measurement of the electron spin were always up and the measured spin of the positron were always down. But because of quantum mechanics, the spin of each particle is both part up and part down until it is measured. Only when the measurement occurs does t...

Not all campuses may meet your standards for physical accessibility, so it’s important to do your research. Tulkin suggests considering the physical layout of the campus and the weather. Stahl advises checking to ensure that campus buildings are physically accessible wi...
Economics does not naturally lend itself to scientifichypothesis testingas does physics. In the field of epistemology, scientists can learn through logical thought experiments, also called deduction, or through empirical observation and testing, also called positivism. Geometry is a logically deductive sci...
