<p>I had a flipped classroom for my topology lecture. It was one of my absolute favorites.<p>We had no lectures, the teacher just gave us a short, concise textbook to read a chapter of every week.<p>In class time was devoted to discussing and problem solving.<p>But yes, it only worked because we were a small class of 15 math students</p>

<p>I think there is some room for debate here about the political bias of wikipedia, and there is <i>some</i> evidence to suggest a left wing bias.<p>However this article is pretty venomous and the author doesn't even make an attempt at masking their disdain for the other side. It's not written in good faith.<p>I'd prefer if someone shared a more cool-headed article on the subject</p>

<p>Small piece of product feeback related to grammar:<p>The landing page asks, how are you feeling? For which the possible responses are "Anxiety", "Procrastination" ... "Overwhelm".<p>When a person says, I a X, X is always an adjective. One doesn't say "I am Irritability" one says "I am irritable".<p>All of these options are nouns, except for "Overwhelm" which is actually only a verb but is being used incorrectly as a noun.<p>The correct responses would be "Anxious", "Hyperactive", "Overwhelmed", "Irritable".<p>Except for "Procrastination", which doesn't have any associated adjective. You might need to rephrase the whole header</p>

<p>I have some more tips, specifically pertaining to Germany and your requirements:<p>> Language: In Germany you can get around no problem with 0 German. Me personally I downloaded Duolinguo the day before my flight and I did just fine learning as I went.<p>> EU financial foundation: I'd say you can just build a US financial foundation then send it over via bank transfer when u arrive.<p>> Established living situation: If you get accepted to a german university, try to show up at least a month before courses start. Take that time to open a bank account, get insurance, enrol and find an apartment. Do NOT try to find a rental  when you don't have boots on the ground, there are a bunch of scams that target international students trying to secure accomodation. For your first month or so, just stay in an airbnb until you find a place you like long-term<p>></p>

<p>My Qualifications: I moved to Germany for 7 years<p>I can only add my voice to what others have said: Just apply to universities and get your student visa.<p>In general it is very difficult applying to jobs in countries from abroad, and in many countries they have laws requiring that companies must prove that they couldn't source talent locally first.<p>Meanwhile student visas are very easy to get, and after you are in the country on a student visa, you can seek part time work, or get a job as soon as you graduate. Many countries offer fast-track residence permits for expats who have graduated from one of their universities.<p>My story: I applied to a german university, got accepted, and got the student visa relatively painlessly. After graduating I found a job relatively quickly and got a work permit.</p>

<p>Okay we are are getting a little lost in definitions here, but nonetheless.<p>You can solve the above by remembering that the dirac delta is the limit of a series of functions.<p>If you take your delta to be lim a -> 0 N(0, a) where N() is the normal distribution, then you can see that in your above equation, you then have two limits. lim t -> 0 and lim  a -> 0. By swapping the order of the two (which is a dubious operation), you can send t to zero first then a to zero, and the result is zero.<p>So in one way, it can be deformed to zero, in another way it can't, because it's 0 times infinity .<p>However, the thing to focus on is that dirac deltas aren't actually valid points in the solution space of partial differential equations. They aren't functions, and they aren't actually physically real.<p>Come to think of it, that would probably exclude them from being TDs a-priori. Because a TD must be a solution to an underlying physical equation, and that solution must be deformable to zero. But if it's not a solution to a PDE (because it doesn't live in any valid hilbert space), then it can't be a TD.</p>

<p>I don't disagree with what you've said about distributions, however I don't think that the fact that these shells are created from dirac delta functions is sufficient to call them topological defects.<p>Topological defects are solutions to the underlying physical equations that are of a different homotopy class to the vacuum, and these simply aren't in a different homotopy class, as I can smoothly deform them to zero, by sending the radius to zero or sending alpha to zero.<p>Argued another way: a point charge can be modelled as a dirac delta charge distribution, but nobody would argue that a point charge is a topological defect</p>

<p>Also, strictly speaking these <i>aren't</i> topological defects.<p>They are massless spherical shells, i.e. a sphere embedded in 3d space and thus can be continuously deformed to a point by sending the radius to zero.<p>Spheres are literally the second homotopy group and the homotopy group of flat space is zero.

<p>Agreed. This paper is pretty much pointless.<p>Its extremely implausible, putting it generously, that such fine-tuned structures could even form. They mention at the end "this paper does not attempt to tackle the problem of structure formation" but that feels like a colossal understatement.<p>I've studied physics myself, and I understand that sometimes people toy around with implausible theories solely for the sake of it but .... it seems like these peoples brainpower could be much better spent elsewhere.</p>
