Even if a highly ultimate technology, would comunicante trough physical means.
 There a wire or even light it's not different from my hands.

We usually call them interfaces. They can be biological neurons, implanted electrodes, or non-invasive brain wave sensors.
Currently, humans can affect matter on Mars, because we have the necessary interfaces and actuators.

I'm just a simple man with a simple mind, so I prefer simple explanations.

I studied industrial electronics engineering in a polytechnic. I'm interested to science in general, especially physics, and more specifically in electromagnetism.
My past and present jobs had me studied programming, communication protocols, industrial instrumentation, power generation and distribution, water treatment, microbiology, chemistry, statistics, and some other things.

I'm also interested in philosophy, which should encompass all bodies of knowledge. Although in current stage, it seems lack of clarity and suffers unresolved disagreements among philosophers. I hope it can be improved soon. IMO, we need to be more consistent with our definitions, logic, and math as a language to communicate effectively.

New Theories / Re: The theory of the human body special mass

« on: 24/04/2022 09:46:52 »

The idea is crazy try to think of this: my body is 60 kg and when I lift it I must exert the same force I exert to lift a heavy rock of 60 kg but I move or lift lighter body of say 20 kg even though it should be heavy like the rock.
I think like this can be thought of : people are familiar with lifting or moving heavy loads do you think you really jump, dance , walk, run, walk upside down,etc doing these with a load of your body 70 kg?

How many times can you do pull ups?
How much additional weight can you carry while pulling your own body up?

What is the x force on the scale ?
Why an x appears when I lift my body?
When I lift my body the x force appears, what is the relation between the force I press on the scale and the value of the x on the scale?

When you lift your body from a stationary position, the center of your mass must first accelerate upward.
The force x = your mass times your acceleration. But since parts of your body have different acceleration, then x must be integrated from parts of your body. Your toes are not moving, hence 0 acceleration. On the other hand, your head experiences greater acceleration.
x = ∫a dm
Once you reach highest velocity upward, you need to decelerate (or accelerate downward). Otherwise you would fly away from the scale. Gravity would normally provide this downward acceleration, and you only need to reduce your acceleration upward. The weight scale would read lower than your normal weight. In this case, it would read 60-x.
x is the effective deceleration rate, which should be calculated by integration, for the reason I said above.
We can omit the integral by saying that x = a.m, where a is acceleration of your central mass. But when your body changes stance/posture, your central mass will be located at different point in space.
When you stop moving and stay at the higher position, the weight scale will return to show your normal weight, and x=0.

So until there are some major breakthroughs, I suggest that researching limb growth is perhaps a thousand to a million times harder than producing a vaccine against one variant of COVID.

If we think linearly, the obstacles are seemingly impossible to overcome. But technological progress is exponential. If the effectiveness of our technology improve by twice a year, we will get a million fold improvement in just 2 decades.

Kinetic energy recovery is significant at low speeds, so it enhances the performance of a 70 mph stop-start car, but at 200 mph or more continuous travel you are more concerned with aerodynamic drag - airplane speed increases with the square root of power - so there's not a lot to be gained by regenerative braking at the end of a 300 mile journey.

How do you get to that conclusion? Additional mass from battery doesn't significantly add air friction.

If Artificial General Intelligence ever reaches Singularity...

Could then Humans leave the roles of Creating Social Laws, Upholding the Constitutional Values & seeing to it that they are being followed...

In short, could a Super A.I. then be a Leader, Judge & Cop? What they do are basically collecting and processing information to make decisions. Cops working at the field also have some physical things to do, but that's not really a big problem for AI.

Or would even AI learn the magic trick of corruption & start accepting rabbity bribes?

Creating proper Social Laws and Constitutional Values are instrumental goal to help achieving the terminal goal. Misidentification of the terminal goal, inaccurate perception of objective reality, or inaccurate cause and effect relationships among different things can bring unintended results.

In short, what could stop a Super A.I. from being a Leader, Judge & Cop?

What makes humans possessing power learn the magic trick of corruption & start accepting rabbity bribes? IMO, it's desire to get pleasure and avoid pain, which are meta rewards naturally emerged from evolutionary process. To prevent the AI from going to the same path, they must be assigned the appropriate terminal goal and meta rewards from the first time they are designed.

So...what are Politicians taught?

Primarily how to gain and retain power. That include persuading other people to follow their biddings.

Politicians were useful traditionally because decision making process related to a society as a whole could only be done by humans. No other things including machines, could do the job. But humans as individual have their own personal desires and preferences, which may be different than interest of their society. This creates conflict of interest. And problems arise for those who are not in power when personal interest of the politicians win against public interests.

It's a technical problem. Let's say that the technology is advanced enough to scan and record all molecules of the hamster,

Why would we say that, given that we know the uncertainty principle makes it impossible?

Because of variation tolerance for preservation of identity. A hamster now isn't exactly the same as it was a few seconds ago. We still call it the same hamster.

If one is dead there are no electrochemical messages being sent around.

Static memories don't need messages being sent around. Think of a CD/DVD.

And then stop thinking of CD/ DVD because they are not really how the brain works.

Some parts of the brain act like memory storages. That's the topic of this thread.
If the brain can be frozen quickly enough, it's possible to restore the brain functionality in the future, including memory. It has been done experimentally with small mammals, like hamster.
Otherwise, it will deteriorate pretty quickly. CD and DVD deteriorate too, but at much slower rate.

   By argument, I hope you mean discussion.  I'm fine with you defining 0⁰ =1  if you want to.

The word discussion is more suitable to replace the word debate. The argument from authority itself is a widely known logical fallacy.
https://en.wikipedia.org/wiki/Argument_from_authority

In this discussion, one side think that 0⁰ is defined. The other side think that it's undefined. We try to convince the other side that our thought is better than the other. Many mathematical proofs are in the form of reductio ad absurdum, i.e. following the implications of an assumption to the point of absurdity/contradiction, to conclude that the assumption is false, hence we choose its opposite. 
Arguing that our position is better because it's supported by an authoritative body can be useful in cases where each sides of the discussion have inadequate capacities to gather and process necessary data to produce correct and reasonable conclusions. Laymen discussion on complex problems like climate change or how to handle a pandemic are often cited as examples. Statements from the authorities can save our time and energy.
But if the goal is to find the fundamental truth, we need to process the raw data ourselves, and determine why a position is better than the other without relying on what the authority said.

It turns out that there may be a technical fix for that too. By contraception, we can prevent some of them from existing in the first place. Neuroscience is revealing how brains work, which can give access to read them, and even modify them in not so distant future.

0 + 0 = 0.

0 * 0 = 0.

0 / 0 = 1.

0 ^ 0 = Undefined.

0 - 0 = Nothing.

Ps - Dyscalculia!
👻

I would switch the third and fourth: 0/0 = undefined and 0⁰ = 1

Let x be a number very close to 0.
let c be a finite non-zero number.
xc/x = c
x^xc = 1
thus
0/0 = undefined
0^0 = 1
