Positive liberty is the possession of the capacity to act upon one's free will, as opposed to negative liberty, which is freedom from external restraint on one's actions. A concept of positive liberty may also include freedom from internal constraints.The concepts of structure and agency are central to the concept of positive liberty because in order to be free, a person should be free from inhibitions of the social structure in carrying out their free will. Structurally, classism, sexism, ageism, ableism and racism can inhibit a person's freedom. As positive liberty is primarily concerned with the possession of sociological agency, it is enhanced by the ability of citizens to participate in government and have their voices, interests, and concerns recognized and acted upon.
Isaiah Berlin's essay "Two Concepts of Liberty" (1958) is typically acknowledged as the first to explicitly draw the distinction between positive and negative liberty.
An atom has an equal amount of positive and negative charges. But those charges are not all in exactly the same spot. Electrons are closer to other atoms than the protons are. So, would a lone positive charge be attracted towards the electrons in an atom?

For example, I have a pendulum with amplitude of 2m, when the pendulum is at a displacement of 2m, wouldn't the acceleration be negative as the restoring force is acting towards equilibrium? The equation I am taught is that maximum acceleration is (2*pi*frequency)^2 * amplitude, which is a...

Homework Statement
Q1= 200 C

Qtotal= Q1+Q2 ?
The Attempt at a Solution
Qtotal=Q1+Q2=400-200=200 C
Is it possible to connect the positive plate of C1 to the negative plate of C2 and vice versa without the capacitor getting explode ?
Two positive charges Q1 and Q2 are separated by a distance d. Find a general expression for the distance from Q1 at which the electric field is 0 by defining Q2 as alphaQ1 (alpha > 0 with alpha not equal to 1). This expression should contain alpha, d, and possible some numeric constants. Check...

In class we were given an example where \frac{dP}{dt}=P(a-bP). We found the critical points to be P=0 and P=a/b. We wanted to know if the derivative is always positive or negative between the two critical points. The prof said you could pick an arbitrary point between the two, such as...

I don't understant how the positive electrode can attract both electrons and the positive Li ions as they both flow to it. Also, the way to start the whole process is to let the electrons flow, right? (Close the circuit.) Without it, the ions also don't want to start flowing, although there is...
While studying Yang-Mills theory, I've come across the statement that
there exists a positive-definite inner product on the lie algebra ##\mathfrak g## iff the group ##G## is compact and simple. Why is this true, and how it is proved?
Given positive real values $a,\,b,\,c$ such that
$a^2+b^2+ab=9$
$b^2+c^2+bc=16$
$c^2+a^2+ca=25$
Evaluate $(a+b+c)^2$.

If you've noticed that I've already posted this problem before, please kindly send me a PM so I could delete this one. Thanks in advance.
I am a student of 11th standard and being introduced to Bernoulli's principle made me wonder , how does flow takes place in positive pressure gradient (i.e. from low pressure region to high pressure region), in a diffuser or a diverging part of a venturi meter , since we know that flow always...
Hi,
I have a rather trivial question but google did not really help me. So far I was always familiar with the fact that the determinant of a square matrix is positive.
But it is not. When I randomly execute det(randn(12)) in MATLAB I get a negative determinant every couple of trials...
I need to find a high capacity (60-90 gpm) pneumatic pump that is able to pump 2.8 cP (fairly low viscosity) dirty water reliably. there's no need to worry about discharge pressure or suction head, because the level in the vessel provides plenty of head pressure.
