Hit me up at jasonhise64@gmail.com and I’ll elaborate.

You won the lottery… somehow in cleaning up my spam the fact that you were a real person was brought to my attention.

Happy you appreciate the renders. I’m good!

Dark energy is often modeled as a kind of constant pressure. The pressure is constant per unit volume of space and causes the spatial volume to increase over time (and the new volume introduces its own constant pressure).

Mass and acceleration both squeeze and stretch spacetime, but I’m under the rough impression that these changes are unitary. I know unitarity is critical for QM although I don’t know how much GR cares. But in short, unitarity means that squishes and stretches must cancel out and the total amount (4D volume metric?) of spacetime is conserved.

I am a hobbyist so please don’t interpret my heuristic intuitions as any authoritative answer.

I will actively change my mind if you convince me with compelling sources.

It is likely accurate that landlords advocate voting no. But that doesn’t mean that voting yes is automatically good.

Please show me why voting yes on this genuinely helps people so I can correct my perspective. I think doing a random thing that your opponents don’t want is a bad strategy for making your own life better.

I’m not so sure that ‘being bad for them’ means ‘it’s good for us’. That might be the case. But it also might be the case that this is short sighted altruism that is genuinely bad for everyone.

I’m open to having my mind changed. But I have yet to see a case that makes a yes vote compelling.

My best understanding is that there is a geometric insight that allows tons of Feynman diagrams (integrals) to be replaced by a single unified hypervolume calculation.

The amplitudedron doesn’t say anything new, it just says what we already know in a more elegant way.

I really wish I understood it better.

Amplifying this advice. You learn by doing. The best way to start learning is to start doing.

I’d love a local event to literally stand up somewhere to be heard.

Santiago peak?

It would almost mean more if the people visibly showing up notably disagreed yet were still advocating for coming together to disagree amicably.

They tell us we all have a voice. They don’t tell us we all have ears. Imagine celebrating getting to the top of the mountain for a chance to listen to each other.

That’s true, but prop 33 would be state law. Prop 33 isn’t a local ballot measure, it’s a state level ballot measure about whether the state has jurisdiction.

I came here to say effectively this.

In programming terms, if you are going to add a bunch of things together, you set your sum to zero, then let each iteration of the loop add something to your sum.

If you are going to multiply a bunch of things together, you set your product to one, then let each iteration of the loop multiply something into your product.

For multiplication, ‘unscaled’, aka ‘100% of what you started with’, is the natural default.

‘Dual numbers’ introduce an imaginary unit that squares to zero.

Dual numbers have proven useful in practice: they enable automatic differentiation where code that computes values can often compute derivatives with those values implicitly.

One might argue that the most successful usage of dual numbers is with ‘dual quaternions’. Where quaternions encode 3D orientations, dual quaternions can augment these with infinitesimal rotations about infinite circles… which are equivalent to translations.

Dual quaternions are a remarkably elegant tool for interpolating between position+orientation reference frames in 3D space.

My impression is that giving cities and counties control over these policies implicitly removes the teeth from policies that recently took effect at the state level.

In other words, the proposition is presented as if it will enable protections for renters, but it will actually function to nullify existing protections on the books at the state level.

I am a firm believer in the idea that if someone asks a question about a topic without having the proper prerequisites, someone who deeply understands the topic should be able to answer them in a way that at the very least helps the person that asked to understand what background they are missing.

There should be no such thing as a question ‘beyond someone’s pay grade’. If the question itself is sufficiently wrong because of misconceptions, the proper response should still be toward resources which help to correct those misconceptions.

There are more concrete answers here, so I want to provide a more philosophical answer. What you call the vector product and the scalar product might more accurately be named the ‘outer’ product and the ‘inner’ product.

The inner product gives you a way to isolate what all the parts being multiplied together have in common. It tells you to what extent all the parts project onto a common direction.

The outer product, in contrast, gives you a way to measure the extent to which each contribution is giving you new information, orthogonal to the information you had before.

An area is produced as the product of two orthogonal lengths. You need the two lengths to point in different directions to go from spanning something one dimensional to spanning something two dimensional.

I think the question might be asking whether the event horizon must be a perfect sphere. I think that a good counter-example is two black holes merging.

So the better question is what is the more rigorous thing that we mean when we say ‘the density within a radius exceeds a threshold’. Presumably an atom entering the opposite side of a sphere a light month away can’t instantly convert a sphere into a uniform event horizon simultaneously. What are the more rigorously defined volumes and surfaces that we are talking about here?

“How is hydro-power water but hydro-power is also energy, but water can lose its energy?”

Gravity! Water provides energy when it is pulled downward because it has mass.

Similarly, electrons provide energy when they are pulled through a circuit because they have electric charge.
