Quantum Mechanics
Quantum Mechanics is the branch of physics that deals with the study of the structure and behavior of atoms and molecules. It is primarily based on Max Planck's Quantum theory, which incorporates Heisenberg's uncertainly principle and the de Broglie wavelength to establish the wave-particle duality on which Schrodinger's equation is based.

What is the significance of zero point energy in quantum mechanics?
Did Einstein study quantum mechanics?
actually einstein developed one of the earliest parts of quantum mechanics: the theory of the photoelectric effect. he worked directly with many of the scientists that later developed the complete theory of quantum mechanics and the mathematics to solve its apparent paradoxes to get usable predictions from the theory.
later he rejected it due to it being nondeterministic, not because he didn't understand quantum mechanics but because he did understand quantum mechanics. he then tried to combine quantum mechanics and general relativity, hoping the resulting unified field theory would resolve the nondeterminism of quantum mechanics, resulting in a single fully deterministic theory of everything.
What does the study of biomechanical mechanics involve?
The study of biomechanics involves the study of biological systems, in particular their structure and function as related to their mechanical methods. This can apply to any life form, including humans.
What should happen as a filament in a light bulb gets hotter?
The basic idea is that eventually it gets hot enough to glow.Please note that this is not a very efficient way to produce light; a lot of the energy is wasted. Nowadays, better methods are available.
How is the electron cloud related to the modern model of an atom?
The atom where we are most likely to find an electron. this area is called the electron cloud.
Where did Planck discover quantum theory?
Max Planck was a full professor at the University of Berlin when he noted that black body radiation could be easily explained if one assumed that light could only exist in discrete "chunks" equal in energy to a constant times the frequency of that light. At the time he published his work, and for many years afterwards, Planck felt it was only a mathematical curiosity; it was only later that he concluded that these quanta (later called photons) were a real, physical entity.
Why do satallites have to stay in the equotorial plane?
Staying at the "same point" (i.e., above the same location on Earth) is only
important for a Geosynchronous satellite, which must occupy a very high orbit.
Most satellites (and the International Space Station) are in lower orbits, which
means they orbit the Earth faster than it rotates, so they don't stay in the
same place.
===================================
Answer #1:
Now to deal with the question . . .
If the satellite is going to be used by non-technical people with little 'dishes'
on the corner of their house or garage, it's important that they not need to
move their dish to follow the satellite across the sky. If people couldn't "set
it and forget it", there would be no Dish network or Direct TV or any of the
others, because very few customers would be willing to do what it takes to
keep their dish tracking the satellite. Sure it could be automated, with a
motorized mechanism that constantly steers the dish to follow the satellite.
But that would cost 20 times what those dinky dishes cost now, and again,
the operators would not "have a business". The only way that this whole
scheme of satellite-direct-to-the-home can work is to make the satellite
motionless in the sky. The installer comes to your house, mounts the dish,
'finds' the satellite, points the dish in that direction, and locks it permanently
in that position. That's the only way the business model can work.
When did max planck discover quantum theory?
Max Planck proposed the concept of quanta in 1900, leading to the development of quantum theory. This marked the beginning of modern quantum physics and revolutionized our understanding of the behavior of matter and energy at the atomic and subatomic levels.
Why was quantum mechanics invented?
Quantum Mechanics is one of the three branches of Modern Physics, being the other two, Classical Mechanics and Relativist Mechanics.
Quantum Mechanics is needed to learn the intimate behavior of the smallest particles existent: subatomic particles. It deals with the interaction amongst, the forms of energy they receive and deliver, and the way they emit energy, a way done in packets, or quanta, also called photons.
Quantum Mechanics is one of the base knowledges for the design of modern electronics.
What are the entropy and enthalpy?
Enthalpy is the energy of the molecules. It cannot be measured, although CHANGE in enthalpy of reactions can be measured. It's simply heat energy. Exothermic reactions have anegative enthalpy change(which means energy of the products is lower than that of the reactants). Endothermic reactions have a positive value(energy of products is higher than that of the reactants). Entropy, on the other hand, is the degree of disorder. It's the measurement of how disordered a substance is. For example, particles in a solid are regularly arranged, so they are less disordered, and have a low value of entropy. Gases have much higher entropies. Entropy of an individual compound can be measured/calculated.
Who stated an Electron Must Occupy The Lowest Available Energy Orbital?
While I am not sure who stated it, that's a general tendency in nature, and not just for electrons - i.e., for systems to go to the lowest possible energy level.
Conditions of uncertainty refer to situations where outcomes are unknown or unpredictable due to lack of information or complexity. Decision-making in uncertainty requires acknowledging risks, embracing ambiguity, and being flexible in response to changing circumstances. Strategies like scenario planning, risk analysis, and fostering adaptability can help navigate uncertainty effectively.
Orbital shapes are conic sections.
A closed orbit is elliptical. That can include circular, but that's very unlikely, since the circle
is just an ellipse whose foci happen to exactly coincide.
An open orbit is hyperbolic. It can also be parabolic, but that's very unlikely, since the parabola
is just the exact boundary condition between closed and open orbits.
What are applications of uncertainty principle?
Uncertainty Principle can be used to give a drawback to Bohr's Model of an atom.
In that atomic model Bohr said that electrons exist in certain well defined energy levels, to give a contradiction to this statement uncertainty principle may be used.
What happens to an electron during an electron transition?
Drops to a lower energy level and emits one photon of light.
How did Erwin Schrodinger make his discovery?
He came up with an amazing equation that describes very small things, and proposed a ridiculous thought experiment.
When did max plank discover the quantum theory?
Max Planck discovered that radiant energy was a proportional to the frequency of the radiation, E=hf and the constant of proportionality is Planck' Constant, h.
What process does nuclear energy go through?
If you're referring to nuclear energy in power generating plants, it is nuclear fission. If you're referring to the nuclear energy in our Sun, it is nuclear fusion.
How big is a barn in standard units?
Chicken barn sizes vary depending on the number of chickens that need housing. The chicken barn should provide enough room for the chicken to be comfortable moving around and nesting.
What is the evidence for quarks?
Every particle that should exist if quarks are real has been found.
No particle that should not exist if quarks are real has ever been found.
The results of in-elastic scattering between hadrons fits perfectly with quark.
The hypothesis of charm quarks predicted experimental results that were almost perfectly replicated with the discovery of the psi-particle.
In other words, the quark hypothesis matches observation perfectly.
That's about as strong of evidence as can exist.
How do you identify the number of shells an atom has?
To determine how many shells are in a particular atom, you learn all about a modern periodic table. You also learn to count. Let's see. What are the elements in the first group? Hydrogen and Helium. What is the first shell? The s shell. Bravo. What are the elements in the group? It starts with Lithium. The first two elements have the s shell; the next two have the p shell. Now lets go to the Third level. Why don't you learn the formula?
As you all know that light travels in a straight way but how light bends at the cornor?
Light always travels in a straight line with respect to space-time. If it appears to the observer that the light beam has bent it can only be concluded that space-time is bent.
