The self is an individual person as the object of its own reflective consciousness. Since the self is a reference by a subject to the same subject, this reference is necessarily subjective. The sense of having a self—or self-hood—should, however, not be confused with subjectivity itself. Ostensibly, this sense is directed outward from the subject to refer inward, back to its "self" (or itself). Examples of psychiatric conditions where such "sameness" may become broken include depersonalization, which sometimes occurs in schizophrenia: the self appears different from the subject.
The first-person perspective distinguishes self-hood from personal identity. Whereas "identity" is (literally) sameness and may involve categorization and labeling,
self-hood implies a first-person perspective and suggests potential uniqueness. Conversely, we use "person" as a third-person reference. Personal identity can be impaired in late-stage Alzheimer's disease and in other neurodegenerative diseases. Finally, the self is distinguishable from "others". Including the distinction between sameness and otherness, the self versus other is a research topic in contemporary philosophy and contemporary phenomenology (see also psychological phenomenology), psychology, psychiatry, neurology, and neuroscience.
Although subjective experience is central to self-hood, the privacy of this experience is only one of many problems in the Philosophy of self and scientific study of consciousness.

Hello all, I am a high school senior applying to college this year and have a question.
Like many others on these forums, I have done a lot of self-studying of physics in my spare time, purely out of interest.
How should I include self-study on a college application, and for for those you who...
Hello,
Quantum Physics is a topic that I didn't study in college, and, I do not know why, is calling my attention lately.
Just to mention my background, I had 2 physics courses (mechanics and electromagnetism), and I used to study from Physics 1 and 2 by David Halliday, Robert Resnick, in early...

Hello everyone, my question is: Would be ok to use a self locking gear like a worm gear for a solar tracker system on a 2 ton parabolic mirror dish? Would it be necessary some kind of brake system, or the worm gear would be enough?
If so, are there any type of self locking gears besides the...
I am a freshman (ore med). My curriculum does not have physics until junior year of college. I want to take the MCAT at the beginning of junior year. I am reading the AP Physics textbook of my high school (I didn't actually take AP Physics, I just bought the textbook) and while I am learning a...
I hope this is posted in the correct thread.
When I was still in my physics class, we learned that a loop of wire with current can act as a self inductor.
Just to refresh my memory:
A loop of wire carrying current has a magnetic field around it due to current, however if the current changes...

The Binomial Distribution - already developed by Jacob Bernoulli (in 1713), et alii, before Abraham de Moivre (1667-1754 CE), et alii, developed the Normal Distribution as an approximation for it (id est, the Binomial Distribution) - gives the discrete probability...
Hi,
I'm a 19 year old boy who's never been in a maths or physics high school class for a number of reasons.

Any good textbooks on differential geometry for self study?
I'm not the best at reading comprehension. I've already studied Calculus, differential equations, and linear algebra.

Mechanics -- factored self weight of an object
How would you find the factored self weight of an object, suppose you are given the the dimensions and mass per metre of the object. Would you find the unit weight first by multiply by 9.81 and then multiplying the volume to find the UDL?
In the case of self induction, when the intensity increases gradually an emf is induced which generates a back current " equal in magnitude, opposite in direction " to oppose the increase, so if that is right shouldn't the intensity in the coil Become ZERO till the intensity becomes steady?

The well-known connection between the electric field and Coulomb's law is that

These two equalities yield the F=qQ/r^2...
