How to reconcile interest in two (somewhat related) disciplines
How to do research in two very different fields?
Today I came across an ad on this question on SO:  (I don't expect it to stay very long).   There was a community promotion ad on the right hand side of the site, I think for one of our English sites. It had a sentence that I only partially remember:     Idiom ... poor or even poorer   I found it interesting, so I clicked that ad. Which caused a new instance of SO to open within the ad space. Unfortunately I failed to take a screenshot. I've been refreshing the page like crazy, but can't get the ad to appear again.  Edit: I managed to get a new community add, for the photography site, and captured a screenshot:   Edit2: This bug still persists, I saw it today with an OOP add from CodeReview, and an area 51 add.

Who fired the shot and what is the symbolism in firing shot right next to Lucas at the end of the movie? At the end of , during the deer hunt, there’s a shot fired right next to Lucas (deliberately missing the shot).   Who fired the shot? Is it Theo's son? What is the meaning of that scene? Is someone warning Lucas that he made a mistake and definitely, Lucas will be punished in the future? Was Voldemort a Better Wizard Than Dumbledore? Pursuant to , I have a somewhat related question. The majority of Harry Potter readers automatically assume that Dumbledore must be a better wizard than Voldemort, because Dumbledore is &quot;good&quot; and Voldemort is &quot;evil.&quot; However, would Tom Riddle's prematurely developed skills demonstrate that Voldemort was inherently a better wizard than Dumbledore? In chapter 17, The Heir of Slytherin, Harry challenges Tom Riddle when he claims to be the greatest sorcerer in the world, retorting that Albus Dumbledore is the greatest sorcerer in the world. Harry reminds Tom Riddle that Voldemort is frightened of Dumbledore. Conversely, in Half-Blood Prince, Dumbledore himself states that Voldemort knows perhaps more magic than any other wizard alive. Yet, as Harry is J.K. Rowling's most direct voice, do we conclude that Dumbledore was, in fact, the superior wizard? Who was the better¹ wizard: Voldemort or Dumbledore? ¹Better meaning on a technically skilled level. A matrix and its transpose have the same set of eigenvalues/other version: $A$ and $A^T$ have the same spectrum Let $ \sigma(A)$ be the set of all eigenvalues of $A$. Show that $ \sigma(A) = \sigma\left(A^T\right)$ where $A^T$ is the transpose matrix of $A$. No module named numpy I am trying to run Jupyter notebook from my Ubuntu subsystem in Windows 10. I've installed numpy, scipy, and pandas using the following commands:  pip install scipy numpy pip install pandas   When I load python in Ubuntu, there is no issue importing numpy in Ubuntu cmd.   But, when I run my Jupyter Notebook from Ubuntu terminal, and try to import numpy as np, or import pandas as pd, they report  ModuleNotFoundError                       Traceback (most recent call last) &lt;ipython-input-1-a9340201ed9f&gt; in &lt;module&gt;       5 import dash_html_components as html       6 import plotly.graph_objs as go ----&gt; 7 import numpy as np       8 from dash.dependencies import Input, Output       9   ModuleNotFoundError: No module named 'numpy'   Is there anyway to solve this issue? Thanks a lot. Change the URL in the browser without loading the new page using JavaScript How would I have a  action that may have some effects on the current page but would also change the URL in the browser so if the user hits reload or bookmark, then the new URL is used?

Once I did that, the text for the question title in the moderator queue changed from:     How to use handler to display images from database without passing ID in querystring?    to     How to use handler to display images from database without passing ID in querystring? [undefined more votes needed]    The text on the main page has stayed consistent with the new 'on hold' verbiage, however.  Here's a screenshot: Reviewing a suggested edit from a review queue jumps to the suggested edit queue I was in the first posts review queue and chanced on a post with a suggested edit. (Note: I have enough reputation to review suggested edits.) I clicked on “edit (1)” and was taken into the suggested edits queue. When I approved the suggested edit, I was taken to the next suggested edit, and so on until there were no more suggestions (“There are no items for you to review.”, still in the suggested edits queue). In this situation, I think it would make more sense if I was brought back to that post I was working on in the first posts queue, as soon as I acted on its suggested edit. Alternatively, the suggested edit should be shown in the same kind of pop-up as on a question thread page. The same goes for other queues (late answers, low quality, etc.). Can we re-request features that were declined a sufficient while ago? Purpose of hole in stove leading to oven I'm staying in a hotel and have access to a "electric coil stove" for one of the first times.  I accidentally turned on the oven light and saw that the light was shining up through only one of the stoves:    There's only a port from the oven into the top right stove, and note that the stove is not on.  Here's a view from within the oven:    Is there a hole here as a vent for the oven for some reason, or is this for the stove? I typically use a glass "flat-top stove" that doesn't have an oven underneath it. I've never seen a direct hole from a stove to the oven before, and have to wonder what the purpose is.

Like many questions on TeX.SE, it contains some TeX markup in its title.  Unfortunately, on , this markup gets parsed and rendered as math:    I propose that either:   the entire Hot Network Questions sidebar should be excluded from MathJax parsing by styling it with the tex2jax_ignore class, or at least, any hot questions from TeX.SE should be so excluded from MathJax parsing.   Or I suppose we could always implement , which asks for all questions with TeX in the title to be excluded from Hot Network Questions entirely.  That might be throwing out the baby with the bathwater, though.    Ps. This issue is partially masked by , which causes MathJax not to be rendered in many elements that are hidden by default and revealed using jQuery .show(), such as all but the first five questions in the Hot Network Questions sidebar.  The  user script contains a generic fix for that bug, so users who have it installed will see this issue more frequently, but it occurs even without SOUP whenever a question with TeX markup in the title happens to show up among the top five hot questions that are always visible by default. What to do when the correct answer to a question changes over time? My question concerns . I asked the question, and at the time selected the correct answer. However, time passes and libraries get updated, and now a different answer is actually correct.   I should probably select this new answer as the correct answer, but I feel bad for the person that will lose 15 reputation points even though is answer was the a good answer at that given point in time.  Any suggestions?
