I've noticed that when I read about ethics, "consequentialism" is sometimes described as a broader category of which utilitarianism is only an example, but sometimes the word seems to be used simply as a synonym for utilitarianism. I have never heard of any consequentialist moral theory that is n...

What is "figure-eight logic" meaning in this context: Laura Ingraham’s show on Friday night was a particularly captivating example of the figure-eight logic we resort to when our stories don’t align with reality.

I have three vectors: v1={1,0,0} v1={0,1,0} v1=1/2{1,1,1} I wish to show the volume constructed by these vectors. I know the amount of this volume is calculated by 1/2 Dot[Cross[{1, 0, 0}, {0, 1, 0}], {1, 1, 1}] But I do not know how to draw this volume!!!

In lecture today my professor mentioned that PIN junction make better solar cells than PN junctions. Why is this true? The PIN junction will have a wider depletion region which means it'll have a lower capacitance, so wouldn't PIN junctions be able to store less energy, right? Also, the electric ...

Let $f\colon I \times X \to \mathbb{R}$ be a map where $I \subset \mathbb{R}$ is an interval, $X$ is a Banach space (possibly non-separable) and we have $$t \mapsto f(t,x) \text{ is measurable}$$ $$x \mapsto f(t,x) \text{ is continuous}.$$ My question is: given $w \in L^1(0,T;X)$, is $t \mapsto f...

Assume that bits $A$ and $B$ each have .5 bits of entropy per bit.

I'm inclined to think yes because marginal cost only depends on variable cost (fixed costs don't matter), but I'm not 100% certain. Basically, my thought process is that marginal cost of producing one additional unit is the change in total variable cost to produce that unit. So, my current idea i...

Just out of curiosity. If you get assigned a squawk code and you don’t like it can you request a new one? I get assigned 4666 today and I kind of feel weird about it. Didn’t think about it too much that time but just think this might be a interesting question to ask.

According to No-Nonsense Quantum Mechanics: How is it that $p_1 \in \mathbb{R}$ given that momentum of, e.g. a particle in space has to require a 3-dimensional vector to be fully described? For example in classical mechanics, momentum can often be written as $\vec{p} = m\vec{v}$.
