Logically, if the only proof of existence we have is what we can see, hear, smell, touch, taste, and feel the movement of, why do many philosophies deal with issues outside the physical? Due to these scientific limitations of not being able to prove anything nonphysical (not limited to entities/ concepts surrounding spirituality and religion[s]) exists in any concrete way that affects our daily lives in ways that WE OURSELVES don't choose it to, why doesn't philosophy eliminate these concepts?
Nonphysical entities cannot be observed. Therefore such entities cannot be verified by observation. How could statements like "God exists" be even considered true? Why would anyone appeal to the metaphysical realm at all?  It seems to me that the best method by which we should go about in understanding the world is by initially ruling out the possibility of the metaphysical altogether for the simplest answer (a sort of null hypothesis). Once we can get a hold of a natural cause of some phenomenon, we should be satisfied that that is all there is to it. Formulating some nonphysical cause would be unnecessary, superfluously complicated, or even cluttered. Now if there was some problem that we were certain could not be solved by observation or experimentation or whose solution could not possibly exist in the observable realm, yet must be true, I would consider the possibility of a metaphysical cause.      That said, I don't think that if you can't empirically observe something, it doesn't exist; rather, I would declare total agnosticism and say that it is unknowable.
My understanding is that in machine learning it can be a problem if your dataset has highly correlated features, as they effectively encode the same information.  Recently someone pointed out that when you do one-hot encoding on a categorical variable you end up with correlated features, so you should drop one of them as a "reference".  For example, encoding gender as two variables, is_male and is_female, produces two features which are perfectly negatively correlated, so they suggested just using one of them, effectively setting the baseline to say male, and then seeing if the is_female column is important in the predictive algorithm.  That made sense to me but I haven't found anything online to suggest this may be the case, so is this wrong or am I missing something?

I can't remember the author other than that it was a known older author.  I initially thought maybe Saberhagen or Harrison, but can't find it in their bibliographies.  It involved a collection of 4-5 people from different times/places.  The distinctive bit I can remember was that one of them (not the main character) was a cyberpunkish woman from the "future" of 1999 who spoke in futuristic dialect of English that the other characters, including the protagonist, from the "present" (from the eighties) could not understand.  Unfortunately, I don't remember much else of the plot other than that they were making their way through ruins. When I use the listings package with frame in my code the frame "breaks" when the page ends and it is open in the end of the page.

However the answer already had a single downvote. I felt this was unfair so upvoted the answer to keep it at what I felt was a fair score. It wasn't until afterward that it occurred to me that I should have perhaps solely voted on the content of the answer.  Is this a reasonable reason for an upvote or should I have left the answer alone? I'm in UV Editor and trying to snap the 2d cursor to the vertex ( while the vertices are visible).

I want to prove that the distance between incentre and orthocentre is $$\sqrt{2r^2-4R^2\cos A\cos B\cos C} $$here $r$ is inradius and $R$ is circumradius. I considered $\triangle API$ ($P$ is orthocentre and $I$ is incentre). I could find  $AP=2R\cos A$, $AI=4R\sin\frac{B}{2}\sin\frac{C}{2} $ and $\angle PAI=\angle \frac{B-C}{2}$. So applying cosine rule I got $$PI^2=4R^2+16R^2\sin^2\frac{B}{2}\sin^2\frac{C}{2} -16R^2\cos A\sin\frac{B}{2}\sin\frac{C}{2}\Bigg(\cos\frac{B}{2}\cos\frac{C}{2}+\sin\frac{B}{2}\sin\frac{C}{2}\Bigg)$$ How to proceed form here ?

Mafia 3 no more damage to be dealt barclay mills How many roots have modulus less than $1$? If roots of the equation   $$x^7 - 4x^3 + x + 1=0$$        are plotted on the Argand plane, how many of them have distance from the origin less than $1$?     I found, by plotting the rough curve of $y= x^7 - 4x^3 + x + 1$ that it has three real roots, out of which two of them have modulus greater than $1$ and one has modulus less than $1$. But I don't know how to do the same for non - real roots. The answer given in my book is that $3$ roots have modulus less than $1$. I wonder about the Adjustments to Cost Basis after a wash sale occur. Considering this  ( from marketwatch.com) where someone: On 1 Dec, 2018 used an amount of money in his account to buy 100 shares of XYZ Co., for $2000 (to make it simple , let's say 1 Feb, 2019 to turn all the transactions into the same year) On 1 Apr, 2019 he sells the shares for $1200, and incurred a loss of 800$. On 10 Apr, 2019 he bought back 100 shares for $1300, and had a wash sale. The 800$ loss gets added to the cost basis of this transaction( and the basis becomes $2100) Now, If on 13 Apr 2019, he sold 100 shares for $1400; I'm pretty sure that the realized Gain/Loss record of this transaction would show something like this: &quot; XYZ Co. shares  100 , Proceeds $1400 , Cost basis  $2100(adjusted), Short-term Gain/Loss  -$700 &quot;. So, even though the Gain/Loss shows a negative number, he still got an actual profit of $100 from this sale, right?
