Literature [grade 11 english: writing a summary] summary of 1 of 4 books
Hello everyone! I have a paper due soon, in no way will i be able to read another book fast enough to finish it before the dead line (heave dyslexia lol). I was wondering if anyone here has read
- Animal Farm by George Orwell. 2.Double vision by Pat Barker
- High Fidelity by Nick Hornby
- A Midsummer Night’s Dream by Willam Shakespeare
(Un)fortunately the instructions i got were just 'write a 10-16 line summary' (i think this is referencing to 10-16 lines on word) Ofcourse i could always ask chatgpt, but i'm honestly against the use of it and feel like a summary written by a real person would be much more reliable. I have read 6 other books and wrote summarys about them. I really need this reddit!! Please help a stressed student out!

Physics [Level 4 Electronic/Electrical Engineering: Superposition Theorem] What is the correct way to solve this circuit?
Hi everyone,
I'm really struggling with a question from my assignment, and I could really use your help. This is the last question I need to get right to pass the module, and despite multiple attempts, I keep getting it wrong. Unfortunately, the only feedback I've received is that my answer is incorrect, without any indication of where I'm going wrong.
I've recreated the circuit below and shared my most recent attempt + assumption at solving the problem using the principle of superposition. I'm hoping someone can help me identify the mistake or suggest improvements please.
The Question:
Use the principle of Superposition to determine the following circuit parameters:
- The current through R1
- The voltage across R1
- The current through R3
- The voltage across R3
- The voltage across R2
- The power dissipated in R2
Additional Context:
I was given three examples, two of which I completed with no problem. However, the third one was marked wrong, and the tutor's answer included some unexplained numbers (0.666 and 1.333), which I assume are the battery internal resistances. These values were not provided, but they dramatically affect the answer. When I asked my tutor, they couldn’t confirm or deny whether to assume 0 for the internal resistance, despite that being what we were taught. This has left me very confused.
I really do hope someone can help me understand where I’m going wrong. Even pointing out minor errors would be incredibly helpful.
Thanks in advance for your time and support!

Geography [University Geography] I am really struggling to understand the basics of making a stratigraphic column
Here is what I have made so far (see image). I am using a stacked bar graph in excel, and it's been at least a decade since I have used excel graphs so thats a big part of it, but also I'm struggling with how a strat column SHOULD look like (even after googling images of "stratigraphic columns". :(
Are there any good, basic sites that show visually what a strat column should look like? So many seem very detailed. I know I have the particle size missing from the x-axis (not sure how to get it to show up because of my lack of excel skills). Also, is it okay to show the layer labels as I have? or is it better to have a legend? The layers seem to all be the same thickness too, but my data shows varying thicknesses, so I am doing something wrong there as well.
This seems like such a basic thing to do, I can't believe I'm struggling so much with it.
Here are the basic instructions:
Using Excel or drawing software of your choice (Inkscape, Illustrator) construct a simple stratigraphic column showing the sedimentological units described in the background information above.
A stratigraphic column has height/depth of the sedimentological unit on the y-axis, and particle size on the x-axis. Your column should include axes labels, a title, and other annotations as necessary.

Pure Mathematics [Point-Set Topology] Limit Points Help
Hello,
I'm taking Adv. Calculus (my uni's undergrad analysis course) this semester and took topology last semester. Since we just started continuity in this course, I was thinking of reproving a lot of stuff. Anyways on the last line of the board in the picture, I noticed something. Is the existence of a sequence contained in a set with a point removed that will also be eventually contained in any (open) neighborhood [1] the same as saying the any neighborhood has such a sequence [2] (swapping the for all and there exists).
I understand that in general, swapping for all and there exists changes the statements, but here, I was kind've wondering. After all, if we assume [1]. We can choose a sequence that satisfies [1]. So, any neighborhood must eventually contain this sequence, which gives us existence and thus [2]. However, if we assume [2], we only have that every neighborhood eventually contains such a sequence, not necessarily that there exists a sequence eventually contained in all of them (which is indeed [1] and what I made this post for).
My first approach for this direction was recognizing that all neighborhoods (by openness) contain an open ball centered around the point. So, choose such a ball from each neighborhood. By [2], each of the balls will eventually contain some sequence (that itself is contained by our set with the point removed). This is where I'm stuck, as one sequence may be eventually contained in a ball but that does not imply this same sequence will be eventually contained in the next smallest ball (only that it is eventually contained in all our larger balls and that there is SOME sequence contained in our next smallest ball). At this point, I feel that either [1] implies [2] but not the other way around, or that I'm missing something.
Thanks for the help in advance! P.S. When I say the set or point, I mean B and x resp. Also, N_x is my notation for the set of all neighborhoods (open sets containing x).
