This paper brings these ideas forward by explaining mean sea level and, more importantly, the geoid. The discussion is grounded in physics from which gravitational force and potential energy will be considered, leading to a simple derivation of the shape of the Earth's gravity field. This lays...
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....
What is an electron in quantum physics? What are quantum laws in quantum physics? What do we mean by wave-particle duality in quantum mechanics? What does mc^2 mean in quantum physics? What does chemistry have to do with quantum physics? What fundamental forces does quantum mechanics describe?
In a quantum computer the fundamental representation of information is a qubit. A qubit can represent not only a 0 or 1, but a combination of both at the same time. Well, what do we mean really by “both”? This is a tricky question, because this is where our everyday experience does...
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...
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...
Living and working alongside local people during a year off abroad can mean you’ll really get to know them, allowing you to develop a nuanced understanding of different cultures and perspectives. You’ll meet all sorts of people and, if you hit it off with them, you might even gain lifel...
The mathematician Peter Shor showed in 1994 that a sufficiently powerful future quantum computer would be able to find the prime factors of integers much more easily than classical computers. Shor's algorithm was the first algorithm ever developed for quantum computers, and it will one day mean ...
Still, how does quantum computing differ from regular computing? While we don’t really want to go down the rabbit hole of technicalities as the team is rather far off from quantum physics, as far as we understand it, this is not just a better and faster way of computing – it has a...
What is quantum superposition and what does it mean for quantum computing? Universe may revolve once every 500 billion years — and that could solve a problem that threatened to break cosmology Could the universe ever stop expanding? New theory proposes a cosmic 'off switch' ...
