The branch of physics concerned with quantum theory.
“quantum physics allows for particles to be in two states at the same time”.
What is quantum physics? It’s the physics that explains how everything works: the best description we have of the particles that make up matter and the forces with which they interact. Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.
The laws of quantum mechanics. Within a few short years scientists developed a consistent theory of the atom that explained its fundamental structure and its interactions. … By 1926 physicists had developed the laws of quantum mechanics, also called wave mechanics, to explain atomic and subatomic phenomena.
As most physicist use them, there is no difference. “Quantum mechanics,” “quantum physics” and “quantum theory” refer to the same thing. Quantum mechanics encompasses all branches of physics known as “quantum.” As most physicist use them, there is no difference.
Broadly speaking, quantum mechanics incorporates four classes of phenomena for which classical physics cannot account: quantization of certain physical properties. quantum entanglement. principle of uncertainty.
This new NASA Hubble Space Telescope image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. During the course of the collision, billions of stars will be formed. The brightest and most compact of these star birth regions are called super star clusters.
The two spiral galaxies started to interact a few hundred million years ago, making the Antennae galaxies one of the nearest and youngest examples of a pair of colliding galaxies. Nearly half of the faint objects in the Antennae image are young clusters containing tens of thousands of stars. The orange blobs to the left and right of image center are the two cores of the original galaxies and consist mainly of old stars criss-crossed by filaments of dust, which appears brown in the image. They dot the two galaxies with brilliant blue star-forming regions surrounded by glowing hydrogen gas, appearing in the image in pink.
The new image allows astronomers to better distinguish between the stars and super star clusters created in the collision of two spiral galaxies. By age dating the clusters in the image, astronomers find that only about 10 percent of the newly formed super star clusters in the Antennae will survive beyond the first 10 million years. The vast majority of the super star clusters formed during this interaction will disperse, with the individual stars becoming part of the smooth background of the galaxy. It is however believed that about a hundred of the most massive clusters will survive to form regular globular clusters, similar to the globular clusters found in our own Milky Way galaxy.
The mind seemed, to the great discomfort of physicists, to force its way into early quantum theory. Also, it predicted quantum computers to accomplish things ordinary computers cannot, which reminds us of how our brains can achieve things that are still beyond artificial intelligence. “Quantum consciousness” is widely derided as mystical woo, but it just will not go away.
Might it be that, just as quantum objects can apparently be in two places at once, so a quantum brain can hold onto two mutually-exclusive ideas at the same time?
Bohr confidently predicted, it makes no difference whether we delay the measurement or not. As long as we measure the photon’s path before its arrival at a detector is finally registered, we lose all interference.It is as if nature “knows” not just if we are looking, but if we are planning to look.
sner molecules can be swallowed up by neurons. Once inside, the Posner molecules could trigger the firing of a signal to another neuron, by falling apart and releasing their calcium ions.
All scientists believe that laws govern the universe and they have utmost faith on these laws with an unconscious and powerful commitment. Tomorrow instead of the quantum theory, a new theory is proposed, and evidence found, these scientists would revise the laws of the universe, but they never abandon their belief in the universe being governed by laws. They are sticklers to rules and laws, and that is a huge belief on the universe behaving in the ways they comprehend.
If you look at the behavior of a single quantum particle, you find that you can’t trace out a classical trajectory with a well-defined position and momentum at all times. This leads to some of the signature quantum phenomena, like the wavelike interference of material particles.
The Antennae galaxies take their name from the long antenna-like “arms” extending far out from the nuclei of the two galaxies, best seen by ground-based telescopes. These “tidal tails” were formed during the initial encounter of the galaxies some 200 to 300 million years ago. They give us a preview of what may happen when our Milky Way galaxy will collide with the neighboring Andromeda
REALITY IS SOMETIMES JUST AN ILLUSION, SOMETIMES IT IS NOT.
Stephen Hawkins said that physics merely predicts observations and that it is meaningless to talk about how it might “correspond” to reality.
Roger Penrose said “
Physics “tells us something new and bizzare about the nature of reality.”, namely, that we live in a multiverse. Physics also tells us that what we learn in physics is that the material universe depends for its existence on a perfect world of abstract mathematical ideas that some of us consciously consume.”
In a multiverse, everything that can happen, does happen.
Quantum physics has an unsettling weirdness about it.
Quantum physics says that things that don’t happen critically influence things that do.
A component of quantum logic allows for contradictions.
All the quantum possibilities that determine the outcome of subatomic events that are already actualities in some parallel universe.
The answer to the puzzle of human consciousness lies in quantum physics, doing the math, is the challenge.
Slipping into metaphysics is always lurking around the equations, that is a problem.
Symmetry is the causal structure built into the creation module. The creation module has a two-way arrow of time that is built into it. They always passed all current information back into the versatile storage unit. These informational totals can’t be changed or deleted.
The closed subatomic quantum system is a duplicate of the macro quantum system. The two systems interact on a binary basis.
