I noticed the other day that the set of polarities and the set of isomorphisms on a projective plane form a group under function composition and I've been investigating to see if it's an interesting group.
I've been looking for the answer to the following question in various places and have been trying to find a proof but have had no luck yet. Anyone have any ideas?
Let P be a projective plane.
Define a duality [; \sigma ;] on P to be a bijective map sending points to lines and lines to points with the property that for each line L and each point p [; p \in L \implies \sigma (L) \in \sigma (p) ;] .
Also, define a projective plane isomorphism [; \tau ;] on P to be a bijective map sending lines to lines and points to points with the property that for every point p and line L [; p \in L \implies \tau (p) \in \tau (L) ;].
Let the set of dualities on P be denoted by Pol(P) and the set of projective plane isomorphisms be denoted by Aut(P).
Notice that [; G = \mathrm{Aut}(P) \cup \mathrm{Pol}(P) ;] forms a group under function composition.
Is Aut(P) normal in G?
So I was in a speech class, it was my last semester. Completely online due to COVID. Our professor assigned us a group speech that we were to record and send to him by the due date. I thought it would be easy enough as he gave us two weeks to work on it and group speeches weren't anything new to me. He even made separate discussion boards for our groups that we could use to communicate. This project was worth 30% of our grade so failing this project meant you would pretty much fail the course.
I wanted to get it done early so we wouldn't have to worry about it so I immediately post a message to everyone in the group asking when they were free to do a zoom meeting to discuss the project. No reply for a few days by any of them. I then post again. This time a little more stern as it didn't seem any of them cared enough to even reply at all. I waited a few more days. At this point we only had a week left before it was due so I just divided up the work and posted what everyone would need to write their portion of the speech about and gave them a date/time that I would be holding a zoom meeting for the final recording to send the professor. Still no reply.
It was now the day before the speech was to be recorded and two days before the speech was due and my group members had not made an attempt to make contact in any form at all.
So I did the only thing I could think of and emailed my professor explaining the situation. But I assumed he would not reply because throughout the entire semester, it took him over a week to reply to any emails I had sent him. I then did the entire group project on my own, which took me the entire night with no sleep. After I finished writing everyone's speech, It was around the time I had scheduled the zoom meeting to record. I joined it out of amusement knowing nobody in my group would be there. Sure enough it was empty. So I did the entire speech myself. But the rubrick really put emphasis on transitioning to our other group members including saying their name. So between every section where it would cut to a different member, I would say something like, And now (My Name) will explain the importance of blah blah, then mute my screen briefly as if to add a cut, put on a different hat, and continue the speech. I did this for all 6 portions of the speech. I turned in the speech shortly after and filled out the "Group Member Role" sheet that was due as well. I just put my name in every box that was supposed to be a different member.

Recently a user made a post asking where everyone on this forum was from, and I saw there were crocheters from everywhere on this Reddit, it's amazing! I love the idea of being connected to so many crocheters online and thought "what if we connected our crochet around the world?"
Here's how it'd work: we'd see who was interested and each crochet one piece of the project, but make enough for everyone who participates to have one (like if we're making a scarf, and there's 20 of us, the first person crochets 20 foundations and the second person crochets the first row on them, and so forth.) We ship it from person to person (in the order of the cheapest shipping costs) and everyone adds to the project. Then in the end, the last person (I volunteer unless someone else wants to) ships each individual project off, with the shipping cost covered by the person receiving it. Then we'll each have an around-the-world- piece!
What do you all think? Is anyone interested and do you have ideas on what to make or how to make it go smoother? Let me know your thoughts!
Edit: There is a lot of interest and I'm getting a lot of messages (yay)! I've set up a discord server for all those that want to join, so if you'd like to be a part of the project, pm me your discord name and I'll add you. We're going to do this!! And if I don't get back to you in a day, please message me again! I want to make sure I don't miss anyone by accident because there are a lot of messages to manage!
Edit 2: WOW this is getting big! It's hard to add you all at once, so I'm getting everyone a blanket invite Link if you're interested! https://discord.gg/MpkRyasq
I'm at work now and it's hard for me to keep up with the messages, so if there's any inappropriate speech I have to address in the server now that everyone can just join, please pm me on discord to let me know! I'm sure that won't happen because everyone here is lovely, but I want to be sure I have a failsafe in place!
Happy crocheting, everyone! This is exciting!
i'm a college student, and i recently had to do a group project that was worth 50 percent of my grade in a class. we didn't get to choose the groups, so i was paired with 4 random people who didn't do their fair share of the work, didn't show up to the zoom meetings, and made constant excuses for themselves. i ended up doing like 75% of the project myself, and tbh, i doubt we're going to get a very good grade.
i could see group projects being a good way to teach kids about teamwork in elementary school, but in college, group projects only mean that you're forced to rely on random people for your grade, and odds are, those random people will end up being lazy and uncooperative. group projects aren't a fair reflection of an individual's effort or knowledge, so they shouldn't be a thing once students are past the age of like 12, and they definitely shouldn't be a thing in college!
I am obviously mad at him for not telling me, but he reassures me that not a single software is going to find out that he plagiarised.
The reason why is because according to him, the content comes from an obscure study guide book, which he bought specifically for this assignment, and he told he there’s very little chance the software will detect it (it’s that book https://www.kobo.com/us/en/ebook/summary-study-guide-elmet).
Now I have two choices, either I tell the professor and he gets punished, but I’ll get a zero mark because the deadline is in 2 hours and there’s no way I can start it all over (and in any case, we had one shot at handing it in, we can’t delete the document). Or, I go along with it and hopefully the software won’t detect the plagiarism.
It’s a very stupid situation, sorry to have to bring it up here, out of all places.
UPDATE: The professor replied to my email saying he’d give my friend a first and final warning (next time he won’t get expelled, but he will have to face a disciplinary hearing that could lead to the same result). In the meantime, since it was just an informal assignment, he’s given me a week’s extension to start it over (on my own this time).
Every fucking semester, EVERY FUCKING SEMESTER there’s a motherfucking group project.
If I see one more group project assignment this semester, I’m gonna fucking lose it.
I’m always stuck with people who will get their parts done last minute, and when emailing professors about this issue, my emails are ignored.
I am convinced, by others and by my own experience, that over-extraction in immersion brews is a myth that causes some people to chronically produce under-developed brews. I think that many recipes for French press and Aeropress are convoluted, over complicated products of our hyped up coffee culture. I hope for a bunch of you guys to brew along with me and educate yourself, with your own equipment, about what works and what doesn’t. I believe you will surprise yourself with how simple it is to make great coffee at home.
Here is a link to a post I made from a couple weeks ago about all of this. It is required reading for this group project. If you participated in the discussion there, thank you. You’ve change my life for the better. TLDR: you can’t over-extract an immersion brew because science. Turns out dramatically long brew times can make some of the best cups of coffee people have ever had.
Here’s what you can do if you want to play along:
-
Read for a bit in the link above. The main post and especially some of the top replies. It will help you understand the situation and what we are trying to accomplish here.
-
Brew an immersion brew of your own and TRY to over-extract it. It can be an Aeropress, a French press, cowboy coffee, or whatever else you want. It just has to be immersion and you have to go finer than you normally would, hotter than you normally would, and dramatically longer than you normally would. Edit: Only constraint is in ratio. Stay in the 1:12 thru 1:18 range.
-
Report here what you did in detail, with what beans, what roast level, and how it tastes compared to your normal brew for that method. I believe you will be pleasantly surprised.
Then we can all nerd out together over the data.
Ready…
GO!!!
Inspired by another post here which triggered the heck out of me. A college project where it was an assigned group of 5, we didn’t know each other. I am convinced teachers do this not so we learn how to work in groups but rather so they only have to mark 6 papers instead of 30.
One of the other four showed up to one of our team meetings once, the others never showed up at all.
The one who did show up brought no work, no laptop, no pen or paper. Was just there.
Everyone had a specific section to work on and we were to present in class as a group. Throughout the term we had a google doc where we could upload our work. One signed on once and did nothing else. One asked one question, “wtf is this even about?”. One said this was stupid and he wasn’t doing it. The other one copy/pasted Wikipedia and that was it.
Everything was divided evenly and every week we were to check in with the professor in regards to questions or problems. I didn't hold back so I simply asked what would happen if I only do my part because the other 4 were flaking out and not even coming to class.
Her response, we'd all fail. So fine I did everything. Day of the presentation they all showed up. It was worth 40% of our grade. The class had a copy of the presentation and the professor had a line by line version of what we were going to present as well as the written report.
I gave the introduction and let the other 4 present their parts. They never once asked to see any of it or read any of it before hand. They were just going to "present". OK
The power point was just a photo, no text and none of them had anything to say. One tried to sum up my introduction and he looked worse for trying. The others simply refused to go to the podium.
What I did not do is put the text on the powerpoint for any of our parts which means I had to memorize my intro, my section and the conclusion.
In my support for the conclusion I summarized what they were supposed to say so it made sense. The written report only had my name on it and I included an addendum for the other four people’s contribution in total. It was a printout of our work google doc with all their names and contributions including the plagiarized Wikipedia.
They were pissed at me for not including the text or specifically, “screwing up their parts”. They didn’t even know the topic of the presentation let alone what they were supposed to say.
My professor said we’d all get the same grade and because 4 of the 5 sections we

But not by me. :')
I have a shit GPA (largely probably from health issues/family being psychotic/ being broke AF) did student government my entire degree that added nothing to my technical skills (although I would argue gave me better soft skills than my peers), and I'm generally decently resourceful/persistent/adaptable.
The one thing I have been good with is getting job offers, internships, being successful at my work. I know lots of engineers with 3.9 GPAs who can't find a job, or those who have found jobs which won't be as high-paying as mine, or who will work for small companies on projects that don't really interest them.
I've made a million mistakes and suffered the consequences. I've also been super lucky and thanked my stars for it because others have not been so.
I'm writing this to say that while I admire and respect people who are going for that traditional high GPA, dean's list, student projects, crazy internships, immediate hire after graduation thing, it's not going to be everybody's path. Actually, I think for most of us that's not the path to success, or more importantly happiness.
I see so many posts here where people are beating themselves up for not falling into that narrow definition of success we have come to know. My message to you is- if I can be happy with what I have, which is certainly different than what you might call a 'succesful engineering student', you can be too. Find a job/internship you like, find student clubs that give you sick stories to tell your friends when you're out drinking, find something that keeps your mind churning out ideas and solutions.
At the end of the day, only you get to decide if you're happy or not. GPA ain't gonna keep you warm at night. A 'dream job' will make you miserable if your boss is a dick. Taking a summer off to travel/hike/ eat good food and improve your health can do wonders for your state of mind and well being. If you're in first year and freaking out about not having a 4.0, or even a 3.0, stop and evaluate whether it's really preventing you from doing that which would make you happy.
Sorry for the huge rant, you guys know all this already, just saw a post on here that inspired me to write this.
When in college, I seemed to get put in the worst groups for group presentations. Most of the teachers didn’t want to hear about issues with group members and that we were just complaining. They would say that we would run into those types of issues in our future careers and we needed to figure out how to deal with these situations. I didn’t want to get a bad grade because the other members didn’t contribute. So, I would often do the whole assignment myself. When it came time to present, we would often switch who spoke with each slide. I didn’t want them to get the credit for my work so I included the largest and difficult to pronounce words I knew or could find in the dictionary. When the other members would start to read off the slide, they would look to me and I would help them pronounce the word, over and over, for the whole presentation. It was clear to everyone in the room that I had actually done all the work without me saying a single thing or complaining about the situation. It was always very satisfying.

This is all stemming from a crazy dream I had last night doing a project with some of the Dallas ladies. Made me wonder who I wish it was with instead. The real answer is none because I earned my degree 14 years ago 😆
imagine you are a 39y old woman in a degree programme in a western country with students in their mid 20s. you are Indian, have decided to shift careers. You have to work in groups for projects. The group has 2 23 year old women who are white American, loud, and very insensitive to you. They don't let you participate in the conversation, when you talk they don't respond, they ignore. They only talk to each other referring each other by name in your presence and do not even look at you. You are very knowledgeable in the subject and have life experience but they don't care to let you contribute.
You are good at the subject but a bit slower in understanding the academic system, the softwares to be used since you have not been in school for nearly 15 years. You are introverted, thoughtful, compassionate and not good at socializing. The programme supervisors and profs are all white and don't give you any help - they act busy, act like you it's your problem, or that they don't see any issues.
What are some strategies to work with these women during the project? You love the subject but the project partners are assholes. How can you go through this programme and get your degree?
EDIT: thank you so much r/india i feel so much better equipped to talk to her
Okay, before I dive into the situation let me explain the class. This class is an online college speech class. And it’s been rinse and repeat since our first speech. Been doing the same stuff in practically the same way.
Okay at the start of November we were Assigned a group project, it started off bad. We couldn’t see who was in what group, but I got the information of my group the next day. And gave them all my phone numbers. We were in contact sooner than the other groups. In the group there was C, K, J, and me.
We had stated deadlines of when everything was needed to be pass to another person, or need to be turned in.
K took on the responsibility of doing the first part (half of the first part) of the project. She had almost a full week, and I needed it by 5 on Friday, because I needed to edit it. That was one part of my job. What she sent me Friday… was not what it was supposed to be. For some context we had been doing the way the professor wanted it from the first speech, and this was the LAST. What K did was write out the ENTIRE speech instead of filling out the outline. Then when asked to do it the correct way a few hours before 5, she told me like 4 minutes before 5 that her computer crashed.
At this point I was done dealing with her, and did it myself. All the work got it done in about 2 hours. Then I went on to edit it and checking all the references, which was my original job. I did end up having to replace two of them. Neither of them was used in the speech. Spent about 45 minutes in all doing that.
That SAME night I also had a meeting with C and J. Told them what happened, and showed them the text that K sent me. We all agreed to take her name out of the group. I mean, that was the ONLY part of the project she had. And not even all of it was hers. J did half of the work on the outline and had it done correctly and gave it to us two days before. Everything else was finished by the time we set.
Now C had to put in new group text after we kicked K out, that K would not stop texting. Even after telling her why we did it. I had to text her telling her to leave C alone.
She told me it was inappropriate to kick her out of the group without telling her. And if it was such a big problem she could have gone to a public library and have it to me tomorrow. Which would have been the Saturday before thanksgiving break. The outline was due Monday, and I was leaving home that Saturday to go visit my sister 5 hours away for the weekend. And while I w

I was doing some research around flats and holy shit it's so overwhelming.
Projects, builders, localities, prices, things to look for while making a purchase and whatnot.
Is there any forum/discord/telegram group where people discuss upcoming projects in bangalore(or real estate in general) ?
Or any website which helps first time home buyers understand the various aspects of flat buying?
Thanks
I'm wondering if others have issues when working in groups for projects, especially ones where you will all share the same mark.
I'm a non-binary, two-spirit 26 y/o who also has c-PTSD and was bullied very badly in school. All throughout grade school I was bullied or at the very least, didn't fit in. I was far ahead of other kids my age and couldn't meet them where they were at. In high-school I came out as queer and was ostracised by my peers, losing all of the few 'friends' I had. I had to change schools because the bullying was so tremendous, but unfortunately the new school was no better and eventually I just had to drop out or else I was going to commit s*icide (I had already attempted twice). This was especially difficult because I was receiving exceptional grades up until I couldn't handle it any more.
10 years into the future and I am now in my first year of university. I had attributed my previous school experiences and disconnection from my peers to growing up in an abusive household and not being straight or cisgender, but now that I am grown up and in safer spaces I find I still struggle to relate to my classmates. Whether it is break-out rooms on Zoom or the group project I am currently part of, I just can't seem to relax and not feel irritated with everyone. It's like no one wants to put in the same effort that I want to. No one wants to communicate directly about expectations and roles. No one is excited about what we are suppose to be talking about. It feels like no one cares except for me, and I fear so much about taking up too much space and yammering on but there are these huge silences because no one wants to talk so I end up trying to create conversation to no avail. I just end up being ignored or eye-rolled, even though I know my thoughts are good and end up being supported/congratulated by my professors when we are put back into the main class. I resent others profiting off of my thoughts and effort when they put in zero.
I'm wondering if this is a common autistic experience within group settings, and maybe if anyone has ways to remedy it? I've emailed one of my professors to see if I can do the group project on my own as I think I will enjoy it much more and not feel so fucking shitty all of the time. I often end up having to turn my camera and mic off while on Zoom to have outbursts because I become so upset and distraught, and I'd rather it didn't come to that anymore because I feel so pathetic when I do. Group chats end up sim

That sounds bad but please read. So in my university psych class we have these group essay projects where we basically split the topic into parts and each write a part. We had two weeks to do our parts, it’s about a paragraph each and we had already known what parts we’re doing, shared the document and everything. It’s really not that much work, my part took about 20 minutes (literally)
So we’re all in a groupchat and after the initial topic selection, no one but one person had said anything or done their part (just me and this other girl, Jess). So the day it’s due comes around (due at 11:59pm) and that night was also the football game that my partner and I bought tickets for and were excited to go to for months prior. It didn’t start until 8pm so it was very likely that I wouldn’t be able to be the one to finish anyone who didn’t finishes part and turn it in (only one person needs to turn it in).
So I send a message to the group that morning asking if someone else can be responsible for turning it in since I couldn’t that night. Only Jess said anything, saying she can’t because she’s an online student in another country so the time zone would make it so she can’t, totally understandable. I wait a bit and ask again, no response from anyone and they still haven’t started their parts. A couple hours from the game and I’m starting to stress because I don’t want to have to skip the game we spent $100+ on but I couldn’t be the one to finish their parts and turn it in if I didn’t do it beforehand. So I talk to the TA and she says to one more time tell everyone that they need their part done by the time I leave (8pm) or I’m going to turn it in without their parts.
After this, one more person does their part but the rest still don’t, so I do their parts and turn it in right before I leave at 8pm, and made note of who didn’t do their part (as the TA told me to), and turned it in. While I was at the game the rest of them I guess finally saw the messages and blew up the chat cussing me out and saying they’re going to get a 0 now and that I turned it in before the due date time so it was unfair. When I saw this I said how that’s what the TA told me to do, and that they had two weeks to write one paragraph, and that I had been asking for 12 hours prior if anyone else can just be the one to turn it in and no one said anything. If someone just offered to turn it in i wouldn’t have had to turn it in early at all. They said they’re going to “talk to the TA” and that
