# What are the best books for understanding quantum mechanics?

Some recommended books for understanding quantum mechanics are "Quantum Mechanics: The Theoretical Minimum" by Leonard Susskind and "Introduction to Quantum Mechanics" by David J. Griffiths. These books provide clear explanations and examples to help readers grasp the fundamental concepts of quantum mechanics. Additionally, "Quantum Mechanics and Path Integrals" by Richard Feynman offers a more advanced and in-depth exploration of the subject.

# What is a quantam state with zero spin?

A quantum state with zero spin is a state where the angular momentum of the system is zero. This means that the system has no intrinsic angular momentum or spin. In other words, it has a spin quantum number of 0.

# Is de broglie wave an electromagnetic wave?

No, the de Broglie wave is not an electromagnetic wave. It is a wave associated with particles, such as electrons and other subatomic particles, and is used to describe their wavelike behavior. electromagnetic waves, such as light, are different phenomena that involve oscillating electric and magnetic fields.

# Does antimatter have the same laws of physics with itself as matter?

Yes, antimatter follows the same laws of physics as matter. Both matter and antimatter are subject to the fundamental forces and interactions described by the laws of physics, such as gravity, electromagnetism, and the weak and strong nuclear forces. However, antimatter particles have opposite charge and other properties compared to their matter counterparts.

# What are important properties of quantum mechanics?

Important properties of quantum mechanics include wave-particle duality, superposition, and entanglement. Wave-particle duality suggests that particles can exhibit both wave-like and particle-like behavior. Superposition refers to the ability of quantum systems to exist in multiple states simultaneously. Entanglement describes the phenomenon where the states of two or more particles become correlated and cannot be described independently.

# Who are founders of quantum theory?

The founders of quantum theory are Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, and Max Born. These physicists made significant contributions to the development of quantum theory in the early 20th century.

# What is the fundamental assumption behind quantum mechanics Who first proposed it?

The fundamental assumption behind quantum mechanics is that particles and systems can exist in multiple states or positions simultaneously, until they are observed or measured. This is known as superposition. The theory was first proposed by Max Planck in 1900, and later developed by Albert Einstein, Niels Bohr, and others.

# What is the field of physics overlapping time and space?

The field of physics that studies the interactions between time and space is called spacetime physics or, more specifically, relativistic physics. This field encompasses Albert Einstein's theories of special relativity and general relativity, which describe the behavior of objects in relation to time, space, and gravity. It explores phenomena such as time dilation, length contraction, and the curvature of spacetime.

# Why normalization in quantum mechanics?

Normalization in quantum mechanics is important because it ensures that the wavefunction describing the state of a system has a well-defined probability interpretation. The wavefunction must be normalized, meaning that the integral of the squared magnitude of the wavefunction over all space is equal to 1. This allows us to interpret the square of the wavefunction as the probability density of finding the particle in a particular state.

# Characteristics of Bose-einstein condensate?

its compose of two (2) significant propertie: Surface tension and Viscosity (just like the liquid matter)

# Are quarks traveling at the speed of light?

Quarks have not been observed to exist separately - they are "confined" within larger particles such as protons and neutrons, that are made up of several quarks (3 each, in the case of protons and neutrons).

# Has the Higgs boson been found yet?

We are not sure if the theorized Higgs boson is real or not. If it is, it would be provide some support to ideas about what mass (and, therefore, gravity, which is associated mass) really is. We're still looking for experimental support that the Higgs boson is real, and now that the Large Hadron Collider is up and running, all (interested) eyes are on CERN and awaiting results.

# What are the Similarities between classical and quantum mechanics?

They both have protons and electrons.

And both the theories agree to the supposition that electrons revolve around the nucleus of the atom. They both state that higher energy electrons are located further from the nucleus.apex approved!!

# What is quantum theory?

Quantum theory is the mathematical representation of the universe assuming that everything is divided into well defined amounts (quanta, plural of quantum if we ignore the context) that behave both like particles and waves.

One of its basic concepts is that nothing is in one defined position but exists as a distribution of probabilities dispersed in space. The particle itself may react at any point, but it has different probabilities of "appearing" at different positions.

Another characteristic of Quantum Theory is that in it, whatever you cannot measure can be in an infinite different amount of states. The actual state you see when you you finally observe the system depends, not only on what you observe, but also on how you observe it.

-----

Quantum theory is the language of all particle theories. It is formulated in a well-defined mathematical language that makes predictions for the relative probabilities of the various possible outcomes, but not for which outcome will occur in any given case.

The word quantum means a definite but small amount.

The basic quantum constant h, known as Planck's constant,and its value is 6.626 x 10-34 Js
The quantum theory of physics was developed in order to explain the relationship between matter and energy at an atomic level as well as subatomic. The theory was created by the ideas of Max Planck, Albert Einstein, Niels Bohr, Werner, and many others. It includes basic ideas of quantum physics. One of the most prominent ideas is that matter acts as waves AND as a particle (wave-particle duality). Another crucial idea to the theory is the uncertainty principle. This principle states that certain pairs of values about matter cannot be simultaneously known. For example, if the position of a particle is measured, its momentum value will become less accurate.
At its simplest - it states that the universe is grainy, that energy (like matter) comes in discrete packets rather than being continuous (as it seems to be).

# What conducts radio waves through space?

Radio waves are not conducted. They propagate. They do not need a medium through which to propagate. They just move.

# What does an alpha decay look like?

It can be difficult to visualize something so small that it cannot be seen directly with any light-based instrument. But we can make a stab at it, so let's do that.

An atomic nucleus is tiny beyond anything we've ever seen. It's really, really small. But picture a fuzzy sphere hanging in space. (The electrons will not be part of the picture because they are far, far away on the scale in which an atomic nucleus would be visible.) There's a little vibrating fuzzy sphere, and something is happening to it. Is it changing shape in subtle ways?

A very short distance from the nucleus, we'll see a tiny fuzzy sphere appear almost out of nowhere. That's the alpha particle, and its much smaller than the nucleus. It is composed of a pair of protons and a pair of neutrons bound together. It's a helium-4 nucleus, but you may have figured that out. The reason it seems to "magically appear" near the nucleus is because the alpha particle is believed to escape the nucleus via the mechanism of quantum mechanical tunneling. In one moment, the nucleus is whole, though it is unstable, and the next instant it has lost some of its mass and the alpha particle appears. That little alpha particle has tunneled out of the nucleus and was not seen actually exiting the mass of that nucleus. We might add that the nucleus has just undergone a nuclear transformation, and we call it nuclear transmutation. Where one chemical element existed before, another one that is two atomic numbers down on the periodic table will be left.

That alpha particle, the one that slipped unseen from the nucleus, will appear, but it won't be still. It will materialize and be off in a flash. It comes away with a tremendous amount of kinetic energy. It's really moving! It will rocket out away from the nucleus and blow through the electron cloud like it wasn't even there. It's a helium-4 nucleus as we mentioned, and its a nucleus without electrons, but it is moving far too quickly to have a high probability of "capturing" any electrons from the atom from which it arose. It isn't taking any "baggage" with it. There will be some "shape changes" in the nucleus of the atom that the alpha particle left, but it ends up a bit smaller and as indistinct in our view as it was in the beginning.

Following the alpha particle farther out, we'll see that little guy slamming into air or whatever else is in its way. These "collisions" will be scattering events, and atoms will be ionized in the process. If any solid material is present, the alpha particle will pretty much be hammered into a stop. Alpha particles don't have a lot of penetrating power. A piece of paper will block them. The alpha particle will then snatch a couple of electrons from just about anywhere around it, and the "transformation" of that alpha particle into a helium-4 atom will be complete.

# Is it true that electrons are arranged in different energy levels in an atom?

It simply means that electrons can only have certain energies. These "levels" are often in terms of n, such as n1, n2, n3, and so on. Let's say that n1=1000 eV (a unit for energy) and n2=2000 eV. It would be impossible for an electron in an atom to have any energy between those two values. This follows true for any energy level; this can be shown better like this: there can be no electron energy found between nx and nx+1 when the electron is in an atom.

# What can the higgs boson do?

If it is found it is expected to explain the various masses of the known particles, if it is not found it might be too massive for the LHC to make. If it is proven not to exist we may have to wait for the Supersymmetry theory to explain particle masses.

# What is beginningless time?

A Buddhist would be best to answer, but here goes...

A common theme in religion and science is the inability to project time back infinitely into the past.

Christianity holds that "In the beginning, God created the heavens and the earth...", before which nothing but God existed.

Modern physics can project back to a singularity (the "big bang"), prior to which we can't give any description, because we can't describe the conditions that led to the singularity.

I'm guessing that Buddhism also has hit this problem - what *can* one say about the time before time began? The answer seems to be that it's a fruitless question.

Time has always been, and didn't "begin" anywhen.

++

I suspect there isn't one simple answer for all Buddhists however here's my thought. As time is relative (from a physics as well as spiritual perspective), beginningless time refers to the entire relative experience. The life of the current universe may be 50 billion years, then the process will begin again - there are countless rebirths of the universe. Time is relative to the physical condition, when the mind is no longer connected to the physical condition the orbit of the earth around the sun (relative time) is unlikely to have any absolute significance.

# What does the model of a sea of electrons help explain?

It helps explain metallic bonds.

# Why don't i understand quantum theory?

Quantum Mechanics is inherently difficult to understand.

In fact the well known physicist Richard Feynman, an expert on Quantum Mechanics, said: "It is safe to say that nobody understands Quantum Mechanics."

# How did Erwin Schrodinger achieve quantum mechanics?

schrodinger's dad worked with albert Einstein. Schrodinger looked up to Einstein and was amazed by his ways of thinking. Einstein inspired Schrodinger to become a scientist.

# What are the benefits of quantum mechanics over classical mechanics?

Well, that depends on what you meant by "benefits". Either way, both of them have their limitations. Classical mechanics can not be used to accurately describe an atom. Just as quantum mechanics would be useless if you were asked to find the terminal velocity of a baseball. Both areas have give us a plethora of inventions and technologies that would not have existed otherwise. Now in terms of learning the topics, quantum mechanics is deemed by some to be more interesting because of its mystery (probabilistic predictions) versus classical mechanic's seemingly dry Hamiltonians and Lagranians. Both topics are very powerful tools that are used to solve complicated problems, and one is not really better than the other but I believe that neither is complete. I hope that helped.

# What is a Scalar Energy Weapon?

Scalar Energy is an esoteric synonym for Static Electricity,

which was the kind of electricity most familiar before Batteries,

Power Plants, Electric Lamps, and is generally considered useless,

BUT, since static electricity machines can be made of Non-Metallic

parts, demonstrations of it seem magical, and using the term

Scalar Energy in commerce is usually associated with fraud,

and claims of new perpetual motion machines. Static electricity

can produce convincing and even useful free power for small lamps

and motors, but generally requires more space than Solar Panels

for the same output, only having any advantage at night time.

Amazing voltage gains are possible with electrostatic machines,

some of which produce Lightning, and in the case of a Van De Graaf

generator, may be confused with a Tesla Coil, which uses another

uncommon form of electromagnetism (High Frequency AC) for

similar Lightning and Spark effects. New secret inventions using

"Scalar Energy", supposedly needing funding for research, are

a common scam.

Amber is called an electret (electricity magnet) because it is non-metallic, and can be electrified (charged) to attract or repel

other non-metallic objects, just like a magnet has been magnetized

and attracts or repels metallic objects. It may follow then, that

Amber (or other "electrets") may be sold for health or magic

in the same way magnets sometimes are. (I do not know how magnets

or electrets affect health.) The word "Electricity" is based on an ancient (Greek or Latin) word meaning "Amber".
