Today, maybe $10k. There are a ton of busts of Octavian that are better preserved. But to Octavian, it was priceless (JK he obviously had this commissioned) to put himself on display for all the plebs, so that they would recognize and revere him. If op is trying to find a formula to quantify the value of art monetarily, this is very difficult, since in all but the last 60 years or so, the main value of art has been it's use as propaganda, and only in rare, advanced societies did the wealthy value art that they didn't commission themselves.

Yes, that’s right. But that does not mean your large scale theory can be applied at the smaller length scales. Otherwise you’re arguing like people did to wind up with the UV catastrophe. This was surely covered before a QFT course.
>>
>>16148105
Such a large scale theory doesn't exist if it doesn't have a small scale explanation. There is nothing to explain. It would be just pseud screeching about things they call laws, founded on nothing. The building blocks of the large scale must precisely match the small scale.

>your theory isn’t valid down to infinitesimally
This isnt even defined. What the fuck do you mean by "not valid"? We are talking about symbols on a blackboard. It isnt relevant if the theory describes or not reality, thats not the issue here but that a completely theoretical calculation gives out an absurd result. Absurd not because it calculated a wrong probability, but an infinite one, which cant happen no matter how wrong a model is.

Agreed. They did tests once where they flipped people’s vision upside down with some glasses. After a while people reported seeing everything the right way up, so their brain was correcting their vision to the “cardinal” representation. I imagine the same thing happening if colors were switched.

that's weird. what if it doesn't come back when you take them off?
>>
>>16146846
Immediate problem? Too literal. One set of brain cells is not the same as another set. In general, synesthesia blocks your path. Others swear linguistics affects qualia resolution. Consider hallucinogens, for example, where tie dye patterns strobe the qualia stream. Until you invoke a subjective definition of qualia that isn't reliant on reference pointers, the conclusion is moot.
As a matter of more concern, the swapping of colors may not come close to describing qualia distinctions. Our rainbows may not appear anything alike at all and suggesting a similarity may pose a grave problem for scientific materialism. Evolutionary pressure indicates that this perception of light would maximize contrast or other feature that improves survival, however the dance to regulate such a feature is far too advance of a property after applying entropy. Consider various facial structures influenced merely by diet over a lifetime. The type of tuning in the mind is significantly quicker and would spawn significant variation. Convergence is unlikely.

>>16148130
>what if it doesn't come back when you take them off?
Then your brain would be misrepresenting your perception. The point is that the concept of qualia is trying to separate subjective experience from physical reality, which are actually inextricably linked because they are different ways of talking about the same thing.

I have asked this multiple times and no one has ever given me a straight answer:

What astrophysical evidence would even possibly count as evidence that the universe is infinitely old? My understanding of the history of western thought is presuming the universe has/has no beginning is fundamentally a theological or metaphysical concern. No amount of finite evidence will ever confirm one over the other because the finite age can always be pushed back one layer of explanation so as to make sense with all of the observations made. What is the consensus on this dilemma in the theoretical physicist community? The way I see it is science simply has no say on whether the universe began to exist, unless scientists inject some metaphysical philosophy into their own theory.

>>16147523
All we can really say is that at some point the universe was a lot smaller. The evidence for this is the CMB, age and types of distant stars, and the fact that the temperature of space throughout the universe is basically the same, because distant points in space are currently too far apart for temperature to be in equilibrium unless at some point they were closer to one another
>>
>>16147615
so there is no evidence that the universe has a beginning at all?
>>
>>16147853
No. Just that it was smaller. And because of the current state of the universe and the way expansion is assumed to work then the universe likely expanded from a very small space, possibly smaller than a single atom. That helps explaining why stuff is so uniform over the whole observable universe, extremely rapid expansion from an extremely small size. That's the big bang theory of course, but it doesn't say where the universe came from, only that at some point about 13 billion years ago it was a tiny ball of pretty much just energy, it was too dense and too hot to form atoms etc. So that ball of energy either appeared out of nowhere, or it was there forever, or it was the end state of a possible previous universe, or some other unknown reason.
>>
>>16147523
one model is that it's pulsing, and could have been for insanely many cycles. supposedly there could be some leakage from previous one, in CMB. but it becomes a question of how much anyway, so we won't be able to peer back 5 cycles ago at some Earth-like planet or something.
or could be like a full reset for everything including causality, right after completely collapsing and right before starting expanding again.
>>
>>16147523
Good question. Led me down a small rabbit hole.
As >>16148020 said, our direct measurements are that the universe was smaller and hotter before, which our models then turn into a timeframe.
But we do also have entropic measurements of the CMB; roughly ~10^89 Kb. It's likely too difficult to create an entropic evolution model into a timeframe, but it should be able to give a maximum constraint. This is where the lack of large primordial black holes plays a big role. As the universe ages, more and more of it will be in large entropy gravity wells. This is a constraint against infinity for our universe.
However, this doesn't necessarily rule out that there was universes before ours, before our cosmic inflation, that kept entropy the same but reduced its density, before our big bang, that returned gravity and black holes to the universe. And there may well be echoes of the prior universe! https://www.livescience.com/63392-black-holes-from-past-universes.html

>Although the overall proportion of those experiencing a psychiatric encounter was similar between the vaginoplasty and phalloplasty groups, suicide attempts were more common in the vaginoplasty group (4.4% vs. 1.7%, p=0.033). The rate of a psychiatric encounter occurring after surgery if an episode prior surgery occurred was 33.9% and 26.5% for the vaginoplasty and phalloplasty groups.

>Darwins finches are different species because they look slightly different
>Humans are a single species even though their physical appearances are wildly dissimilar
Darwin’s finches only look similar to one another if you know fuck all about birds. Two races of people having different coloured skin and a different shaped nose or whatever is not comparable to two species of bird where one is nearly 5 times the weight of the other and fills an entirely separate ecological niche with a different diet. Two finch species aren’t necessarily more physically similar just because you see them as both being vaguely bird shaped
>mutual fertility is between the different races is reduced
No it’s not, mixed race people can have kids just fine. But even if that were the case how many studies on the relative fertility of hybrid vs pure finches have you read to say this so confidently?
>human races have substantially different DNA
>finches all have similar DNA
Darwin’s finches diverged 2-3 million years ago. Humans as a whole have only been around a few hundred thousand years and each human race diverged after that. What makes you so sure the birds are more genetically similar to each other than different humans are? Because it sounds like you’re just making assumptions and hoping nobody will point out what’s wrong

This includes the literal niggers, whom actually have a shitton of stamina.
