Breakedown of common sense and inertial ccordinate systems

In summary, the conversation discusses the concept of a molecule with zero binding energy and its ability to dissociate at different velocities. The discussion also raises questions about the relationship between acceleration and the state of the system. The final question reflects on the acceptance of a seemingly simplistic hypothesis due to its consistent agreement with experimental results.

1. Let us consider a molecule with almost "zero" binding energy. Why does every textbook declare that it should be a molecule if we accelerate it to some high velocity? Why shouldn't it dissociate at some velocity.
2. Inversly. Consider a molecule moving with some velocity. Why it couldn't dissociate at zero velocity?

3. Why such questions? May a molecule size be a length unit? And binding energy energy unit?

Accelaration always change the state of the system. How is it, that after acceleration the inertial system, connected with molecule, is equivalent to initial nonmoving system?

Why so childish hypothesis is accepted and adopted?

Because it agrees with every experiment yet devised to test it.

1. The reason textbooks declare that a molecule with almost zero binding energy should still be considered a molecule at high velocities is because the concept of a molecule is based on the arrangement and bonding of atoms, not just the energy of the system. Even at high velocities, the atoms are still arranged in a specific way and bonded together, making it a molecule. It is only when the energy is high enough to break these bonds and cause dissociation that it is no longer considered a molecule.

2. Similarly, a molecule moving with some velocity may not dissociate at zero velocity because the energy of the system is not solely dependent on the velocity. Other factors such as temperature, pressure, and intermolecular forces also play a role in maintaining the stability of the molecule.

3. These questions arise because of the complex nature of molecular dynamics and the limitations of our understanding of it. While we can measure and calculate certain properties of molecules, such as size and binding energy, they cannot always be considered as fundamental units of measurement. The concept of a molecule is a result of our understanding and categorization of matter, but it is not a fundamental unit like length or energy.

As for the inertial coordinate system, it is a mathematical construct that helps us describe and predict the motion of objects in space. After acceleration, the inertial coordinate system connected with the molecule is equivalent to the initial non-moving system because the laws of motion and inertia still apply regardless of the system's motion. This is why it is a widely accepted and adopted concept.

In conclusion, while the questions may seem childish, they highlight the complexities and limitations of our understanding of molecular dynamics. As our knowledge and technology continue to advance, we may be able to answer these questions more accurately and confidently.
 

What is the breakdown of common sense?

The breakdown of common sense refers to the failure or inability to use logical reasoning or sound judgment in a given situation. It can occur due to various factors such as stress, emotion, or lack of information.

What is an inertial coordinate system?

An inertial coordinate system is a reference frame that is not accelerating and is used to describe the motion of objects. In this system, Newton's first law of motion holds true, stating that an object will remain at rest or in motion with constant velocity unless acted upon by an external force.

How does the breakdown of common sense affect inertial coordinate systems?

The breakdown of common sense can impact an individual's ability to accurately perceive and interpret information, leading to errors in judgment and decision-making. This can then affect the accuracy of measurements and calculations in inertial coordinate systems, potentially leading to incorrect results.

What are some examples of the breakdown of common sense in relation to inertial coordinate systems?

One example could be a person experiencing vertigo while riding on a rollercoaster, causing them to misinterpret the direction of motion and incorrectly perceive their position in an inertial coordinate system. Another example could be a pilot experiencing spatial disorientation, leading to incorrect readings of the aircraft's position in an inertial coordinate system.

How can scientists account for the breakdown of common sense in their research involving inertial coordinate systems?

Scientists can take measures to minimize the effects of the breakdown of common sense by using proper training and protocols, double-checking measurements and calculations, and considering potential biases or errors in their data. They can also collaborate with other researchers and use multiple methods to validate their findings.
