If I was frozen for 100 years and dethawed/rejuvenated by modern science, would I be dead and a new consciousness forms in my place?

The person that is dethawed would remember all of my feelings etc.
but would it really be me?

What if like 1/8th of my brain was damaged and advanced science replaced it with the same neurons etc that I had before?
What if 1/4th? What if 1/2? What if 90% of by brain was destroyed and then repaired to it's initial condition?

What if an exact copy of me is formed? Would that consciousness be me?

Is it the energy flowing in the brain? Is it the neurons themselves?
It it someone spiritual/metaphysical?

Something in the universe must decide these rules.
What is it? How does it work?
How is it that there is a mechanism that destroys and establishes a hard consciousness?

Assume the body is a complex machine.
Without electrical signals your "soul" and all higher cognitive functions are frozen. This would mean you are exactly the same person once an electric shock and thaw has been applied because you are just pouring petrol (heat and energy) into a car that has been left in a garage...

What a sad day it is when a man can so quickly be encapsulated by a mathematical function...but such is the way of progress.

All you need to know is you would be exactly like you would be before you were frozen(and whatever caused you to die in the first place would be cured)
Possibly through some highly advanced nanotech robots.

Try masturbating after doing something productive, your brain will associate completing work with pleasure. After a while you'll receive the same stimulus (although much lesser) without the need for masturbation.

you offset your earning power by a good 6-10 years or so (including having to pay back 200-300k in loans).
high demand for those cushy high paying positions
cutthroat environment of medical school
scheduling your life around your work instead of vice-versa
having essentially a pretty monotonous job, with little actual science involved
having to interact with normies
>>
>>9100103
The downside is that nothing you listed is entirely true, most of it is far more complex and laden with catches than you think, and some is outright not a thing.

The first two issues:
>specialize in radiology
>have a private practice
No. Not unless you're independently wealthy, and in a very specific sort of area. You need referrals for patients insurance to cover it (which means being in some network, with many smaller primary care facilities around. Hospitals generally have their own radiology), you need to actually buy and maintain the equipment, you need to pay staff to do all the paperwork, arguing with insurance companies, interacting with patients, etc. Yet another expense. Many private practices find it financially infeasible for that reason alone, you can't do it all yourself, and staff is expensive.

>save lives
That's not a thing with radiology. You're usually just the one telling them how they're fucked up or unremarkable.

>make 500k a year
Nah. Not if you're on salary, and not if you practice privately. And all the loans. Again, leading back to being independently wealthy. At which point, who cares about your salary? You don't need it. You might not be just playing and filling your time, but you certainly don't need it. Do you know the cost of a minimal CT scanner alone?

By the jimminy geez anon, I don't know where people get this stuff. It's mechanically impossible, a thing of dreams, illusion, and fantasy.

Why is time considered the 4th dimension? it doesn't make sense. Why would the 1st, 2nd, and 3rd dimensions be meters, meters squared, a meters cubed but the 4th be a completely different type of unit instead of meters to the 4th power?

what the fuck did he see?
Could there really be someone or something living down there in the pitch black darkness?

I mean he was deep down there, deeper than perhaps anybody has ever gone, there was even a documentary where they tried to find where he even went and couldn't even get close, he most likely took a bad turn and just kept going in hopes of finding an exit.

What really gets me is why would drop your light source? Dropping your light means 100% GUARANTEED DEATH. So why drop it? I think because he something was chasing him and he ditched the light in order to help him hide, I mean if you have the only light for MILES it would be pretty easy to find you.

>>In the course of my law reading I constantly came upon the word “demonstrate”. I thought at first that I understood its meaning, but soon became satisfied that I did not. I said to myself, What do I do when I demonstrate more than when I reason or prove? How does demonstration differ from any other proof? I consulted Webster’s Dictionary. They told of ‘certain proof,’ ‘proof beyond the possibility of doubt’; but I could form no idea of what sort of proof that was. I thought a great many things were proved beyond the possibility of doubt, without recourse to any such extraordinary process of reasoning as I understood demonstration to be. I consulted all the dictionaries and books of reference I could find, but with no better results. You might as well have defined blue to a blind man.
>>At last I said,- Lincoln, you never can make a lawyer if you do not understand what demonstrate means; and I left my situation in Springfield, went home to my father’s house, and stayed there till I could give any proposition in the six books of Euclid at sight. I then found out what demonstrate means, and went back to my law studies.

>Lincoln law partner Billy Herndon relates how Lincoln studied Euclid’s Elements:
>>He studied and nearly mastered the Six-books of Euclid (geometry) since he was a member of Congress. He began a course of rigid mental discipline with the intent to improve his faculties, especially his powers of logic and language. Hence his fondness for Euclid, which he carried with him on the circuit till he could demonstrate with ease all the propositions in the six books; often studying far into the night, with a candle near his pillow, while his fellow-lawyers, half a dozen in a room, filled the air with interminable snoring.

centripetal force.jpg
59KB, 591x718px
Why do we teach that centripetal force is the main force, while the centrifugal force is the reaction force?

Isn't it much more intuitive to think of it the other way?

Centrifugal tries to break the mass off the string, similar to how an applied manual force tries to pull things.

Centripetal is a reaction to the centrifugal, similar to how a structure opposes human-input force.

obviously the "human input" in circular motion is the circular motion itself, and petal and fugal both arise from that. But the fugal force acts in the direction that breaks the string, so it's more similar to an applied manual force.

>>9096505

Moreover, the apparent centrifugal force (imagine a can on a rotating string with a marble inside it, the marble stays on the end of the can not tied to the string) acts by itself, without a centripetal force.
>>
>>9096505
centripetal force is the force in an inertial coordinate system that causes an object to turn (ie the component of force orthogonal to motion).

centrifugal force is a fictitious force introduced by doing your physics in an non-inertial (read accelerating) reference frame. it is not a "reaction force", or whatever.

centripetal is the easier to understand of the two.
>>
>>9096513
>centrifugal force is a fictitious force introduced by doing your physics in an non-inertial (read accelerating) reference frame. it is not a "reaction force", or whatever.

Why not? Centripetal points inward, and is a real force. There's a reaction for every force. So the fugal force is real.

I don't see how reference frame matters. Petal will always point inward. Fugal will always point outward. This is true even if I'm watching from an inertial reference frame.

Fugal is easier to understand, because physically unbound objects experience the fugal force.
