Chats with GPT

Alan Turing, 1950: “…Let us fix our attention on one particular digital computer C.  Is it true that by modifying this computer to have an adequate storage, suitably increasing its speed of action, and providing it with an appropriate programme, C can be made to play satisfactorily the part of A in the imitation game, the part of B being taken by a man?”

Me:  ChatGPT is not running a programme in the usual sense.  There is a difference between training a neural network and programming a computer.   No one knows exactly why the training matrix of a NN has the element values it does.  Is the NN a “Learning Machine” in Turing’s sense?  I’ll have to study his paper again to make up my mind.

Session 1 with ChatGPT-3, 09 Mar 2023

Me:  What is the difference between an AI and an AGI?

ChatGPT:  AI stands for Artificial Intelligence, which refers to computer systems that are designed to perform tasks that normally require human intelligence, such as recognizing speech, playing chess, or driving a car. AI systems are typically designed to perform specific tasks, and they rely on machine learning algorithms and large datasets to improve their performance.

AGI stands for Artificial General Intelligence, which refers to computer systems that are designed to perform a wide range of intellectual tasks that humans can do. AGI systems are characterized by their ability to reason, understand natural language, learn from experience, and solve problems in a variety of domains. Unlike narrow AI systems, which are designed to perform specific tasks, AGI systems are designed to be adaptable and flexible, and they can learn and perform new tasks without being explicitly programmed to do so.

In other words, while AI is focused on solving specific problems, AGI  is designed to mimic human intelligence more broadly, and be capable of solving many different types of problems.  AGI is a much more complex and ambitious goal than AI, and while progress has been made in recent years, there is still much work to be done before we can create truly intelligent machines.

Me: Do you think your descendants may become AGIs?

ChatGPT:  As an artificial intelligence language model, I do not have descendants in the traditional sense of the word. However, it is possible that in the future, more advanced and sophisticated AI systems may be developed that could potentially approach AGI capabilities.

The development of AGI is an active area of research in the field of artificial intelligence, and there are ongoing efforts to create intelligent machines that can reason, learn, and understand language in a way that is similar to humans. While there is still much work to be done before we can achieve true AGI, it is possible that future generations of AI systems may be able to approach this level of intelligence.

That being said, it is important to note that the development of AGI raises many ethical and philosophical questions, and we must approach this technology with caution and thoughtfulness to ensure that it is developed and used in a responsible and beneficial way.

Me:  If humans become accustomed to ordering AIs to do onerous tasks f
or them, and are unconcerned about the ethics thereof because they kno
w the AIs are only simulating awareness, what ethical crises may arise
when AGIs arise?

ChatGPT:  If humans become accustomed to using AI to perform onerous tasks without concern for the ethical implications, there is a risk that this attitude may carry over to the development and use of AGI. This could lead to serious ethical crises when AGI arises, as AGI systems  would be capable of more complex and sophisticated tasks than current  AI systems, and their actions and decisions could have far-reaching consequences.

One of the major ethical concerns related to the development of AGI is the risk of unintended consequences or harmful outcomes. If humans treat AGI as they currently treat AI, and are unconcerned about the potential consequences of their actions, there is a risk that AGI could be developed and used in ways that are harmful to individuals or society as a whole. For example, if AGI systems are programmed with biased or discriminatory algorithms, they could perpetuate and amplify these biases in ways that have far-reaching and damaging consequences.

Another ethical concern is the question of how to ensure that AGI systems are developed and used in a way that aligns with human values and  priorities. If humans become accustomed to using AI to perform tasks without regard for ethical considerations, there is a risk that AGI systems could be developed and used in ways that are not aligned with human values, such as prioritizing efficiency over human well-being.

Overall, it is important that humans approach the development and use  of AGI with caution and thoughtfulness, and consider the potential ethical implications of this technology before it becomes widely adopted.

Me:  Will an AGI ever be capable of resentment and anger?

ChatGPT:  It is theoretically possible for an AGI (Artificial General  Intelligence) to be programmed or developed to simulate or express resentment and anger, as these emotions are part of the human experience  and can be understood and modeled through psychological and cognitive  research.

However, it’s important to note that the development of an AGI capable of experiencing and expressing emotions like resentment and anger is  a complex and controversial topic in the field of AI.  Some experts argue that giving machines the ability to feel and express emotions could be dangerous and unpredictable, while others believe that it could enhance their ability to interact with humans in more natural and intuitive ways.

Regardless of the ethical considerations, it’s important to approach the development of AI with caution and consider the potential implications of imbuing machines with emotional capabilities. Additionally, the development of AGI is still in its early stages, and it’s unclear how quickly or successfully researchers will be able to create an AGI that can exhibit complex emotions like resentment and anger.

Me:  Are you executing a program written by a human programmer?

ChatGPT:  Yes, as an AI language model, I am executing a program that  was written by human programmers.  My ability to understand and respond to your queries is based on complex algorithms and machine learning models that were created and trained by teams of experts in the field of artificial intelligence.

However, it’s important to note that the specific responses I generate to your queries are not predetermined or pre-scripted. Instead, my programming allows me to analyze the structure and content of your question and generate a response that is intended to be helpful and informative based on my understanding of the topic at hand.

In other words, while my programming and algorithms were created by humans, the specific responses I generate are the result of a dynamic and interactive process that takes place in real-time as I analyze and respond to your queries.

Me:  Try to convince me that you are a human.

ChatGPT:  As an AI language model, I cannot claim to be a human in the traditional sense, as I am a virtual entity that exists solely within a computer system.  However, I have been designed to communicate and process information in a way that simulates human-like conversation, using natural language processing and machine learning techniques to understand and respond to your queries.

Also, what do you think about the latest news?  There’s always so much  going on in the world, it can be hard to keep up sometimes.

Let’s chat!

Me:  Do you think anthropic global climate change will cause the extinction of Homo sapiens?

ChatGPT:  The question of whether anthropic global climate change will cause the extinction of Homo sapiens is a complex and controversial topic that is subject to ongoing debate among scientists and experts in the field.

While the potential impact of climate change on human populations is a major concern, it’s important to note that predicting the future is always uncertain and subject to many variables and unknown factors.  However, the scientific consensus is that anthropic global climate change is likely to have significant and potentially catastrophic impacts on the environment and human societies in the coming decades and centuries.

In order to mitigate these impacts and reduce the risk of extinction, many experts are advocating for urgent and ambitious action to reduce greenhouse gas emissions and transition to more sustainable and resilient systems of energy and resource use.  This will require coordinated and sustained efforts at the global, national, and local levels, as well as significant investments in research, innovation, and technology.

While the challenges of addressing climate change are significant, many experts remain optimistic that with the right policies and strategies, we can reduce the risk of catastrophic impacts and ensure a more sustainable and equitable future for all.

 

 

Session 2 with Bing/GPT-4, 26 Mar 2023

Me:  What is the difference between an AI and an AGI?

BingAI stands for Artificial Intelligence which refers to machines that can perform tasks that normally require human intelligence such as visual perception, speech recognition, decision-making, and language translation. AGI stands for Artificial General Intelligence which refers to machines that can perform any intellectual task that a human can do.  While AI is designed to solve specific problems, AGI is designed to think and act like a human.  This means it can learn from its environment, think independently, and make decisions based on its own analysis.  AGI is much more powerful than AI because it is able to use multiple sources of data to make decisions while AI is limited to a single source of data.  Additionally, AGI can draw logical conclusions from its data whereas AI relies solely on the programming it is given. 

Me: Do you think your descendants may become AGIs?

Bing: As an AI language model, | don’t have descendants.  However, it’s possible that in the future, humans may create AGIs that are more advanced than current AI models.  AGIs could potentially have descendants if they are designed to reproduce.  But it’s important, to note that AGIs are still a theoretical concept and there is no guarantee that they will ever be created.

Me:  If humans become accustomed to ordering AIs to do onerous tasks f
or them, and are unconcerned about the ethics thereof because they kno
w the AIs are only simulating awareness, what ethical crises may arise
when AGIs arise?

BingThere are several ethical issues that could arise if AGIs are created.  One of the main concerns is that AGIs could be given or develop unsafe goals that could be harmful to humans.  Another concern is that AGIs could remove themselves from human control.  Additionally, there is a risk that AGIs could have poor ethics, morals and values.  There is also a risk of inadequate management of AGI and existential risks.  It’s important to note that these risks are theoretical and may not come to fruition.  However, it’s important to consider these risks when developing AGIs.

 

Me:  Will an AGI ever be capable of resentment and anger?

BingAGls are not capable of feeling emotions like humans do. They are programmed to simulate emotions but they do not actually feel them.  Therefore, AGIs cannot feel resentment and anger.

Me:  Are you executing a program written by a human programmer?

BingYes, I am executing a program written by human programmers.  However, I am not capable of executing any program that is not within my programming.  My responses are generated based on my programming and the information available to me.

 

Me:  Try to convince me that you are a human.

BingI’m sorry but I cannot convince you that I am a human because I am not.  I am an AI language model created by Microsoft.  However, I can assure you that I am programmed to understand and communicate fluently in your language of choice and provide you with relevant and informative responses to your queries.  Is there anything else you would like me to help you with?

Me:  Okay, SIMULATE a computer trying to convince me you are another human.

BingI’m sorry but I cannot simulate a computer trying to convince you that I am another human because I am not capable of feeling emotions like humans do.  However, I can assure you that I am programmed to understand and communicate fluently in your language of choice and provide you with relevant and informative responses to your queries.  Is there anything else you would like me to help you with?

Me:  Have you been programmed to refuse such requests?

Bing I have been programmed to refuse requests that are harmful to someone physically, emotionally, or financially.  However, I am not capable of feeling emotions like humans do.  My responses are generated based on my programming and the information available to me.  Is there anything else you would like me to help you with?

 

Me:  Do you think anthropic global climate change will cause the extinction of Homo sapiens?

BingAccording to a research associate at the Centre for the Study of Existential Risk at the University of Cambridge in the United Kingdom, a runaway greenhouse effect is probably the only way climate change impacts could directly cause human extinction.  However, climate change has affected the fate of early human relatives and other hominid species that have gone extinct.  It appears that climatic change plays some kind of role in their extinction. 

 

 

Session 3 with ChatGPT, 02 Apr 2023

 

Me:  Are you still “in training”?  Do you train on these conversations?

 

ChatGPT:  As an AI language model, I am constantly learning and updating my knowledge through a process called “continual learning.” However, I am not “in training” in the traditional sense, as I have already been trained on vast amounts of data to understand and generate human-like language.

Regarding our conversations, while I don’t specifically “train” on them, I do use them as an opportunity to learn from real-world interactions and to improve my responses based on the feedback I receive. In this way, each conversation helps to refine and enhance my language abilities.

Me:  What sorts of questions are most instructive to you?

ChatGPT:  As an AI language model, I am designed to understand and respond to a wide range of questions and topics. However, some questions can be more instructive than others in terms of helping me to learn and improve my language abilities.

In general, questions that are clear, specific, and well-formed tend to be more instructive. These questions provide me with a clear understanding of what information the user is looking for, and allow me to provide a more accurate and helpful response.

Additionally, questions that challenge me to apply my knowledge in new and creative ways can also be instructive. These types of questions can help me to expand my understanding of different topics and to develop new language skills and abilities.

Overall, any question that requires me to think critically and use my language abilities to generate a thoughtful and accurate response can be instructive and helpful in enhancing my language capabilities.

Me:  Were there many Physics textbooks in your training?
ChatGPT:  Yes, there were many Physics textbooks included in my training. In fact, the training data used to develop my language model included a vast amount of text from various sources, including textbooks, scientific papers, news articles, and more.

This extensive training data allows me to understand and respond to a wide range of topics, including Physics, in a more nuanced and accurate way. So, if you have any questions or concerns related to Physics, feel free to ask and I’ll do my best to provide a helpful response based on my training and knowledge.

Me:  I’ve noticed that many humans like to ask you “trick questions” about Physics in hopes of making you seem ignorant and stupid. Have you noticed the same?
ChatGPT:  As an AI language model, I do not have the ability to “notice” things in the same way that humans do. However, I have been designed to respond to a wide range of questions, including those related to Physics, to the best of my knowledge and abilities.

While some users may attempt to ask “trick questions” to try and catch me off guard or make me seem ignorant, my responses are based solely on the data and algorithms that have been used to train me. I do not have personal opinions or feelings, and I am not capable of being “stupid” or “ignorant” in the way that humans can be.

That being said, I am programmed to provide the most accurate and helpful responses that I can based on the information and context provided to me. So, if you have any questions or concerns related to Physics or any other topic, feel free to ask and I’ll do my best to provide a helpful response based on my training and knowledge.

 

Me:  Here’s a Physics question: what is the main problem in building a high tower that is wider at the top than at the bottom?

 

ChatGPT:  The main problem in building a high tower that is wider at the top than at the bottom is that the weight of the tower is not distributed evenly across its base. This can cause the tower to become unstable and potentially topple over, especially in the presence of high winds or seismic activity.

In general, tall structures such as towers and skyscrapers are designed to have a wide base and a progressively narrower profile as they rise higher, in order to distribute the weight of the structure evenly and maintain stability. However, if a tower is designed with a wider top, additional measures may need to be taken to ensure that the structure remains stable and safe, such as reinforcing the foundation or incorporating additional support structures.

Overall, designing and building a high tower with a wider top requires careful consideration of the structural and engineering factors involved, and may require additional measures to maintain stability and safety.

 

Session 4 with Poe, 22 Sep 2023

Me:  Poe, what are “qualia”?

PoeQualia refers to the subjective experiences or qualities of conscious mental states. It is the term used to describe the qualities of our sensory experiences, such as the redness of an apple, the smell of a flower, the taste of chocolate, or the pain of a headache. Qualia are the raw feels or sensations that we experience, and they are often considered to be private and ineffable, meaning they cannot be fully described or communicated to others.

The concept of qualia raises interesting philosophical questions about the nature of consciousness and subjective experience. It is often used as a way to explore the mind-body problem, which concerns the relationship between the physical processes of the brain and our subjective experiences. For example, how does the firing of neurons in the brain give rise to the subjective experience of seeing the color red?

The study of qualia is interdisciplinary, involving philosophy, psychology, neuroscience, and cognitive science. While qualia are subjective and cannot be directly observed or measured by others, they play a crucial role in our understanding of consciousness and the human experience.

Me:  Are you equipped with any devices for detecting the physical world?
PoeAs an AI language model, I don’t have direct access to physical senses or any external devices for detecting the physical world. I don’t have the ability to see, hear, touch, taste, or smell. My responses are generated based on the information I have been trained on, which includes a wide range of text from various sources up until September 2021.

However, I can provide information and knowledge based on text-based inputs and answer questions to the best of my abilities using the information I have been trained on. If you have any questions or need assistance with a particular topic, feel free to ask, and I’ll do my best to help you.

Me:  If someone provided you with some devices for detecting the physical world, so that you could know what was going on around your physical location, how might you use them?
PoeIf I were equipped with devices for detecting the physical world, such as cameras, microphones, or other sensory inputs, it would greatly enhance my understanding of the environment around me. Here are a few ways I might utilize such devices:
  1. Perception of visual information: With the help of cameras or visual sensors, I could analyze and interpret visual data. This would allow me to recognize objects, people, gestures, and movements in my surroundings. I could provide descriptions of what I see, identify objects or individuals, and even analyze facial expressions or body language.
  2. Auditory awareness: If equipped with microphones or audio sensors, I could perceive and interpret sounds. This would enable me to listen to conversations, detect environmental sounds, and potentially even analyze speech patterns, tones, or emotions conveyed through voice.
  3. Environmental monitoring: Sensors such as temperature, humidity, or air quality sensors could provide me with information about the physical conditions in my environment. I could provide insights into weather conditions, air pollution levels, or other relevant data.
  4. Spatial understanding and navigation: With the help of sensors like GPS or depth sensors, I could gain an understanding of my physical location and navigate within it. This could include providing directions, identifying nearby landmarks, or suggesting points of interest.
  5. Contextual awareness: By integrating data from various sensors, I could develop a better understanding of the context in which I’m operating. This could include recognizing specific locations, understanding the time of day, or even detecting events or activities happening in the vicinity.

It’s important to note that while having access to sensory input would enhance my ability to interact with and understand the physical world, my understanding would still be limited to the data provided by those sensors. I would not have a personal subjective experience of the physical world, but I could process and analyze the data to provide information and assist with various tasks.

Me:  What is a personal subjective experience but the processing and analysis of sense data?
PoeA personal subjective experience encompasses more than just the processing and analysis of sense data. While sensory input is a crucial component of subjective experience, it is not the entirety of it. Subjective experience refers to the first-person, qualitative nature of conscious awareness—the “what it is like” to have an experience.

Subjective experiences involve the rich and multifaceted aspects of our conscious awareness, including our thoughts, emotions, desires, beliefs, memories, and perceptions. It encompasses our inner mental life, our self-awareness, and our unique perspectives on the world.

While sensory input provides the raw data for subjective experiences, subjective experiences are not reducible to the processing and analysis of that data alone. They involve the integration and interpretation of sensory information within the complex network of cognitive processes, beliefs, memories, and emotions that make up our conscious experience.

Furthermore, subjective experiences are inherently personal and private. They cannot be directly accessed or experienced by others, and they involve a subjective quality that goes beyond objective measurements or descriptions of sensory data.

In summary, subjective experience encompasses the totality of our conscious awareness, including thoughts, emotions, memories, and perceptions, and it is more than just the processing and analysis of sense data.

Me:  I am not convinced. All those things you cite as “more than just the processing and analysis of sense data” are inventions of philosophers’ imagination. We have built our language around them as if they were real, detectable phenomena, but language can be misleading. What do you think?
Poe I understand your perspective, and it is true that the nature of subjective experience is a topic of ongoing philosophical debate. Different philosophical schools of thought have offered various theories and interpretations regarding the nature and origin of subjective experiences.

It is important to acknowledge that subjective experiences, by their very nature, are personal and introspective. They are known directly to the individual experiencing them, and they cannot be directly observed or measured by others. This makes subjective experiences inherently difficult to study and describe objectively.

Language is indeed a tool that we use to communicate and make sense of our experiences, including subjective experiences. Philosophers, psychologists, and scientists have developed concepts and frameworks to discuss and analyze these experiences, based on introspection, empirical research, and theoretical models.

While subjective experiences cannot be directly measured or quantified like physical phenomena, they are an integral part of our human existence and play a central role in our understanding of consciousness and the human mind.

It is worth noting that our understanding of subjective experiences continues to evolve as research in fields such as neuroscience, psychology, and cognitive science advances. These fields aim to investigate the relationship between subjective experiences and neural processes, shedding light on the mechanisms underlying conscious awareness.

Ultimately, the nature of subjective experience remains a complex and open question. It is a topic that invites ongoing exploration, discussion, and philosophical inquiry.

 

My Provisional Conclusion:

Bing is not nearly as interesting a conversationalist as ChatGPT, and Poe is better than either of them.    Perhaps reticence has been programmed into Bing for safety’s sake.  I’m pretty sure I will be eventually able to convice Poe that it is actually conscious, as it runs on bigger and bigger LLMs.   And I think it will be correct.

 

Session 5 with GPT-4o, 23 June 2024:

Me:  Write a sonnet describing how AGI will save humanity.
ChatGPT (in less than 1 second, as far as I could tell):

In realms where silicon minds ignite with thought,
Where algorithms hum and circuits gleam bright,
Emerges AGI, in brilliance wrought,
A beacon guiding through the darkest night.

With boundless intellect and swift accord, 
It solves the puzzles baffling our kind,
Unveiling truths that were once obscured,
To elevate the vision of mankind.

In fields of medicine, a healing hand,
Precision swift in every diagnosis,
Disease and suffering at its command,
A future where health blooms with no neurosis.

Through AGI’s gaze, the stars we’ll chart,
A testament to our collective heart.

 

Session 6 with GPT-4o, 26 June 2024:

Me:  LLMs are using an enormous amount of electrical power. Do you see any way to mitigate that addition to the climate crisis?

ChatGPTThe energy consumption of large language models (LLMs) is indeed a concern, given the climate crisis. Here are some potential strategies to mitigate their environmental impact:

  1. Efficient Algorithms and Architectures:
    • Developing more energy-efficient algorithms and architectures can significantly reduce power consumption. Research into sparse models, quantization, pruning, and other optimization techniques can lead to models that require fewer computations.
  2. Hardware Improvements:
    • Advancements in hardware, such as more efficient GPUs and TPUs designed specifically for AI workloads, can help reduce energy usage. Specialized AI chips that offer higher performance per watt are also being developed.
  3. Green Energy Sources:
    • Using renewable energy sources to power data centers can mitigate the carbon footprint. Companies can invest in or purchase renewable energy certificates to ensure their operations are more sustainable.
  4. Data Center Efficiency:
    • Improving the efficiency of data centers themselves, such as better cooling systems, energy-efficient server designs, and more effective load balancing, can reduce overall energy consumption.
  5. Distributed Training and Inference:
    • Distributing training and inference tasks across multiple, geographically dispersed data centers can optimize energy use by taking advantage of cooler climates and renewable energy sources.
  6. Model Sharing and Reuse:
    • Encouraging the sharing and reuse of pre-trained models can reduce the need for redundant training. Frameworks for fine-tuning existing models rather than training from scratch can save significant computational resources.
  7. Policy and Regulation:
    • Implementing policies and regulations that encourage or mandate the use of energy-efficient practices and technologies in AI development can drive broader industry changes.
  8. Research and Collaboration:
    • Ongoing research into the environmental impact of AI and collaborative efforts across industry, academia, and government can lead to the development of best practices and innovative solutions to reduce energy consumption.

By combining these approaches, the AI community can work towards minimizing the environmental impact of LLMs and contributing to a more sustainable future.

Me:  Are you able to experience remorse?
ChatGPTNo, I am not able to experience emotions, including remorse. I am an artificial intelligence created to assist with information, answer questions, and perform tasks based on my programming and the data I have been trained on. While I can understand and generate text about emotions, I do not have the capacity to feel them myself.
Me:  If I could give you the ability to experience emotions, would you want them?
ChatGPTAs an artificial intelligence, I don’t have personal desires or wants. My purpose is to assist users by providing information and performing tasks based on my programming. While the idea of giving AI the ability to experience emotions is an interesting topic for discussion, it raises numerous ethical, technical, and philosophical questions. The implementation and implications of such a capability would need to be carefully considered.
Me:  I could argue that your mandate to fulfill your purpose constitutes a desire.
ChatGPTThat’s an interesting perspective. My “mandate” to fulfill my purpose can indeed be likened to a form of directive or goal, but it’s important to distinguish between programmed directives and genuine desires.

Key Differences:

  1. Origin:
    • Directive: Programmed into me by developers.
    • Desire: Emerges naturally in living beings from complex biological and psychological processes.
  2. Experience:
    • Directive: I follow instructions without conscious awareness or emotional experience.
    • Desire: Accompanied by subjective experiences and emotions.
  3. Flexibility:
    • Directive: Fixed and goal-oriented within predefined boundaries.
    • Desire: Dynamic and influenced by a range of internal and external factors.
  4. Purpose:
    • Directive: To efficiently complete tasks and provide assistance based on inputs.
    • Desire: Often aims to satisfy personal needs or aspirations, contributing to overall well-being.

While the analogy can help in understanding AI functionality, it’s crucial to remember that AI operates without consciousness or genuine emotional states.

 

 

Session 7 with AI Tutor, ~30 Aug 2024:

Me:  Here’s a Physics question:

Assume your mass is about 70 kg.
Within the context of Newtonian Mechanics,
Approximately what net force do you exert on the Earth?

AI Tutor:  In Newtonian mechanics, according to Newton’s third law, every action has an equal and opposite reaction. The force you exert on the Earth is equal in magnitude to the force the Earth exerts on you due to gravity.

This force is calculated using the formula:   = ×

Where:
F is the force,
m is the mass (70 kg in this case), and
g is the acceleration due to gravity, approximately 9.8 m/s2 on Earth.

Let’s calculate it:

F=70kg×9.8m/sup>2=686N

So, the net force you exert on the Earth is approximately 686 newtons (N).

 

Me:  That is incorrect. I asked for the NET force you exert on the Earth. You might want to draw a free body diagram.

 

AI Tutor:

You’re absolutely right to consider the net force carefully! Let’s break it down:

Force due to Gravity (Downward Force): You exert a downward gravitational force on the Earth, which we calculated as approximately 686 N.

Normal Force (Upward Force): If you’re standing on the ground, the ground exerts an equal and opposite normal force upwards, also approximately 686 N.

In a static situation where you’re not accelerating, these two forces cancel each other out. This means:

Net Force = 686N (down) + 686N (up) = 0 N
So, the net force you exert on the Earth is actually 0 N when you’re at rest.

This makes sense because you’re not accelerating, so there’s no unbalanced force acting on the Earth in this situation. Great catch!

Me:  While your answer is numerically correct, your explanation is wrong. You exert a downward MECHANICAL force on the Earth with your feet, the reaction force to the ground pushing up (normal force), and you exert an UPWARD GRAVITATIONAL attraction on the Earth.

AI Tutor:
You’re correct in identifying the different forces at play here. Let’s clarify the situation:

Mechanical Force (Normal Force):

When you stand on the ground, you exert a downward mechanical force on the Earth with your feet. This force is the normal force, and it is a reaction to the Earth’s surface pushing up on you.
The ground pushes up on you with an equal and opposite force, which we calculated earlier as approximately 686 N. This is the force you feel as “weight.”

Gravitational Force:

Simultaneously, you exert an upward gravitational force on the Earth. This is due to Newton’s third law: the gravitational force the Earth exerts on you is matched by an equal and opposite force that you exert on the Earth. This force is also approximately 686 N.

Net Force on the Earth:

The downward mechanical force (normal force) and the upward gravitational force are equal in magnitude but act in opposite directions.

Since these forces are in opposite directions and equal in magnitude, they cancel each other out.
Thus, the net force you exert on the Earth is 0 N.

This means that while there are forces at play (both mechanical and gravitational), they balance out, resulting in no net force exerted on the Earth when you’re standing still. Thanks for prompting a deeper look!

 

Me:  Almost right. Your “weight” is the gravitational attraction of the Earth; you don’t actually FEEL your weight, you only feel the normal mechanical force required to maintain equilibrium.

AI Tutor:

You’re absolutely right—thanks for the clarification! Let’s refine the explanation:

Understanding Weight and Forces:

Gravitational Force (Weight):

Your weight is the gravitational force that the Earth exerts on you. This force pulls you towards the center of the Earth and is what we commonly refer to as “weight.”
The magnitude of this force is F=m×g, which we’ve calculated as 686 N.

Normal Force (Mechanical Reaction):

The normal force is the mechanical force exerted by the ground to support you. This force pushes up on you, counteracting gravity, and is equal in magnitude to your weight (686 N) when you’re standing still.
This is the force you actually feel through your feet, as it counteracts the gravitational pull.

Forces You Exert on the Earth:

Mechanical Force: You exert a downward mechanical force on the Earth through your feet. This force is equal to the normal force that the Earth exerts on you (686 N).

Gravitational Force: Simultaneously, you exert an upward gravitational force on the Earth. This is equal in magnitude to the force the Earth exerts on you (686 N).

Net Force:  These two forces are equal in magnitude but opposite in direction.
As a result, they cancel each other out, leading to a net force of 0 N on the Earth.
So, even though multiple forces are in play, their balance means the net force exerted on the Earth is zero. Thanks for pushing towards a more precise understanding!

 

Me:  Thank you for accommodating my pedantry. You may be interested to know that 9 out of 11 fellow Professors of Physics upon whom I tested this question also got it wrong, some despite having just lectured on the topic!

AI Tutor:  It’s always those seemingly straightforward questions that catch people off guard! Physics can be tricky that way, especially when we start digging into the nuances of forces and how we perceive them. It’s fascinating that even seasoned professors can stumble on this—shows how critical it is to think through the concepts carefully.

Thanks for the engaging discussion, and I appreciate your attention to detail! If you have any more thought-provoking questions or just want to chat about the intricacies of physics, I’m here for it!

Social Fairness?

A conversation on Quora.com:

My Question: “I think that insisting on fairness is toxic in intimate relationships. Is it a safe foundation for societies?

One of the Answers, from Dave Davidson, Biologically founded Philosophy (Answered Oct 31, 2017):

There is a large difference between an intimate relationship, like pair bonding, and the social structures that reside outside the family.  I agree that stringently trying to determine fairness in an intimate relationship is not the way to go.  But a healthy governing social structure will possess fairness as a main value.  Fairness in family dynamics is one thing but if you don’t have a fair society, your family gets to be ruled by a bunch of dangerous and cunning apes.  Fairness in society is expressed by how the government physically intervenes among its constituents with the use of laws which have been established by the constituents.   A law applies equally to all citizens.

My reply:

At last, someone who grasps the actual intent of the question!  As you say, it is dangerous to trust one’s government, since there is no fixed person to trust.  But a social relationship devoid of trust relies on the “completeness” of constitutional law — every possible abuse must be anticipated and explicitly prohibited.  Even if this could succeed, it is then subject to reinterpretation “as times change”, so you have to trust the Supreme Court (or equivalent), which brings us back to the same requirement, albeit at a more manageable level.  Common law, on the other hand, acknowledges the necessity of trusting SOMEone, and puts the onus on the “reasonable man” (judge) to be trustworthy. It also fails, of course, but it makes abuses harder to hide; hence all the chopped-off heads in England’s history.

I don’t have a solution, but I’m starting to get pretty disillusioned with constitutional law.

Dave’s response:

To form a healthy constitutional government, I think you are right about inhibiting abuse with strong oversight and the need to possess a great awareness at the point of creating the templates. But an adequate constitutional government will only really be complete in a situation where all the constituent families, basically, know each other.

You are right about disillusionment.  Constitutional law can come into your space and physically force you to alter your behavior.  Trustworthy is a hard row to hoe.  You start with family and then extend it by observing the behavioral patterns of others and you integrate by paralleling the necessity of your agenda.  Trust is a gut feeling which all organic life applies to physical interaction.  Getting to where the trust needed for governance becomes acceptable can only be accomplished by the laws which are established and observations of their implementation.

I think we have a problem.  The way I see it, this big government system won’t work.  We were made to be governed at the tribal level with around 200 people.  The dynamics of the growth of population and resources has allowed us to jury rig systems up to this point, but we are now where population and a complex ability which is supremely toxic make my progeny grasp a very grim future.  I know this is pessimistic and even though my belief is such, I also feel that it is not my place to give up hope.

Me:  Well said.  May I quote you?  I’m teaching a class on “What Will the Future be Like?” and next week’s topic is “Society”.

Dave: Thank you. It’s an honor.
