Emergent Entropic Thermodynamic Force

In summary, Robbert Dijkgraaf discussed the concept of emergent entropic thermodynamic force in a video lecture at Gresham College. This force is described by the equation F\Delta x = T\Delta S, where F is emergent force, T is black body temperature, and S is thermodynamic entropy. He also introduced the quantum thermodynamic constant C_1 and the equations for thermodynamic entropy and black-body thermodynamic temperature. By using integration via substitution, it can be shown that F = mg, which is equivalent to Newton's second law. However, the validity of these equations is uncertain without further clarification on the entropy and the sources of the third and fourth equations.

I have just watched a video lecture from Robbert Dijkgraaf at Gresham College where he describes gravitation as an emergent entropic thermodynamic force. The video link is listed in reference and the equations are defined at time index 44:00.

Emergent entropic thermodynamic force:
[tex]F \Delta x = T \Delta S[/tex]
Where F is emergent force and T is black body temperature and S is thermodynamic entropy.

Quantum thermodynamic constant:
[tex]C_1 = \frac{\hbar}{2 \pi c k_B}[/tex]
Where [itex]k_B[/itex] is Boltzmann constant.

Thermodynamic entropy:
[tex]\Delta S = \frac{m \Delta x}{C_1}[/tex]

Black-body thermodynamic temperature:
[tex]T = C_1 g[/tex]
Where g is surface gravity acceleration.

Integration via substitution:
[tex]F = \frac{T \Delta S}{\Delta x} = \left( \frac{C_1 g}{\Delta x} \right) \left( \frac{m \Delta x}{C_1} \right) = mg[/tex]

Newton's second law:
[tex]\boxed{F = mg}[/tex]

Is there any validity to these equations?

A few questions pop to mind:
What is S the entropy of? (this is very important since apparently 1-D thermodynamics is maybe being used to describe a 3D system here?)
Where do the third and fourth equations come from?

Without solid answers to these questions, no sensible conclusions can be made out of this string of math.

Hoping this helps:)
 

1. What is Emergent Entropic Thermodynamic Force?

Emergent Entropic Thermodynamic Force is a concept in thermodynamics that describes the spontaneous emergence of complex structures and patterns from simple, disordered systems. It is driven by the tendency of systems to increase in entropy, or disorder, over time.

2. How does Emergent Entropic Thermodynamic Force relate to the Second Law of Thermodynamics?

The Second Law of Thermodynamics states that the total entropy of a closed system will always increase over time. Emergent Entropic Thermodynamic Force is a manifestation of this law, as it describes the natural tendency of systems to become more disordered and complex.

3. Can you give an example of Emergent Entropic Thermodynamic Force in action?

One example of Emergent Entropic Thermodynamic Force is the formation of snowflakes. As water vapor cools and condenses in the air, it becomes more disordered and forms ice crystals. These crystals then combine and grow into intricate, complex snowflakes, driven by the increase in entropy of the system.

4. How does Emergent Entropic Thermodynamic Force impact the study of complex systems?

Emergent Entropic Thermodynamic Force is a fundamental concept in the study of complex systems, such as biological systems and social systems. It helps explain how these systems can spontaneously self-organize and exhibit emergent properties, despite being made up of simple, individual components.

5. Are there any practical applications of Emergent Entropic Thermodynamic Force?

Yes, there are several practical applications of Emergent Entropic Thermodynamic Force. For example, it has been used in the field of artificial intelligence to develop algorithms that can self-organize and learn from their environment. It has also been applied in materials science to design and engineer self-assembling materials with specific properties.
