Fun little math trick I find really helpful: the ratio of a mile to a kilometer is within 1% of the Golden Ratio. That means that if you have a good memory for Fibonacci numbers (1 2 3 5 8 13 21 34 55 89) you can convert pretty accurately by taking consecutive Fibonacci numbers.
For example, 89 kilometers is really close to 55 miles (55.3). Or, say you need to convert 26 miles to kilometers: 26 can be written as 21 plus 5, so taking the next Fibonacci number up gives 34 and 8, meaning it should be around 42 kilometers. Sure enough, it's 41.8 km!

a (very rare) math/science post.
hey! so i'm a british student but you'll see me putting things in brackets to help clarify things for my non british readers. so i did my GCSEs (i think the american equivalent is SATs?) back in may and june and one thing about me during my last year of school is i was in some deep shit. so i didn't really do that well. I got a bunch of 6s (B+s) and7 (A) in eng lit. i found i was couple marks off of a grade 7 (A ) in almost all my subjects including math and science. now i can deal with a B in art and a B in sociology because I'm doing them for A levels ( google tells me the americn equivalent is AP examinations) so doing well in them means that my gcse grade will be dismissed since i did better at A level today i asked my math teacher if there was any way i could resit and he cut me the following deal: if i resat my exams in either november or june of next year and got a better grade then he'd cover the fees and same goes for science. now, i just started sixth form/college so i'd have to learn in my own time somehow. i don't have anyone to teach me and i can't afford tutoring but i was offered to sit in the back of lessons during my free period every tuesday and that afterschool i can ask whatever available teacher for help for anything i really really can't teach myself should i go for it? please interact and tell me what you think.

maths problems this long feel like a workout for my brain. also this q was Not worth enough marks for the amount of working i had to do.

first day back at school!! so so lovely to be back, i missed it so much. despite the confusing one-way system i loved being back and seeing my friends & teachers & wonderful school. plus my timetable has loads of free periods this year which i’m super happy about.
summer (even though it’s not my summer holiday anymore lol) studying challenge: what is your favourite ice cream flavour?
raspberry ripple!
What do we say when we are in a Summer School and we are living hard the impostor syndrome life?
We say: I'm gonna take these much-smarter-than-me people and asked them a fuckton of questions. And I won't stop asking until I have absorbed all their knowledge and they've forgotten their own name.
A list of math books
…to read in lieu of an actual math class. So far I have
- Gödel, Escher, Bach: An Eternal Golden Braid by Douglas Hofstadter
- I am Strange Loop by Douglas Hofstadter
- Chaos by James Gleick
- Category Theory by Steve Awodey
I love solving mathematical problems. They calm me and cheer me up. They are like meditation to me.
I’m missing them a lot this week. I'm currently writting a paper and is quite urgent, so I don't have time for them. It isn't that I hate writting, I actually quite enjoy it. But it's been a terrible week and I miss my maths.

Heres the thing you gotta understand about statistics.
“Increases your chances by 80%” does not mean “there is now an 80% chance”.
If your chances were previously 10%, your chances are now 18%, not 90%.
if your chances were roughly 1%, they’re now just slightly less than 2%.
thats how that works.
Hi! Maths and celestial mechanics student here! 😊
I’m looking for more studyblrs to follow!
I’m an astrophysics student. I’m most interested in physics/astronomy/math. I also love books, plants, the beach, and pretty landscapes a lot. And of course I love nice stationery and pens. (These pretty much encompass what my posts are about.)
So reblog this if you are a also studyblr or are also interested in any of those things and I can check your blog out!!
Yesterday was hard.
I'm in some courses all this week, and I don't understand anything that 3 of the 4 speakers say. And I've just met the new PhD student of the department, and he's really smart and he's understanding most of the things. And on top of that my advisor is asking me to finish a big amount of writing. I feel really stupid and discouraged.
So, list of positive things to take into account this week:
- All of the courses are about PDEs and not Dynamical systems (which is my research topic). It's normal to not understand most of them.
- It is a great opportunity to see how people of other topics work, and what are they interests. You don't need to understand everything perfectly. Let go and enjoy.
- I learned a lot from yesterday's poster session, and from other students.
- Next year I would have a very smart PhD partner from who I could learn a lot.
- I am a slow-learner when understanding new topics, and that is okay. I could have other qualities that make me a good mathematician.

I haven’t been at university this week for personal reasons but nevertheless I’ve done so much work and I’m really proud of myself. In particular, I’m so happy with my progress in programming. I managed to write 5 functions in MATLAB 2 weeks before the deadline which I wouldn’t have been able to do at all last semester! Happy days ☺️
Do you know that as a PhD student at my university they let you check out books for 4 months?
Here I am, I become the hoarder of books that I was always meant to be
It’s sad how much of what is taught in school is useless to over 99% of the population.
There are literally math concepts taught in high school and middle school that are only used in extremely specialized fields or that are even so outdated they aren’t used anymore!
Lissajous curves 😍
I remember learning about them fo the first time and thinking they were useless pretty curves, oh how wrong I was!
Now, to me they highlight the importance of resonances on dynamical systems and join number theory with differential equations while being hella cute
I love them

just had a reflection about perfectionism. today I had an exam for which I was prepared very well, but my stupid brain happened and I didn't get the highest grade. my boyfriend was comforting me and he asked since when I want to ace everything, this question made me think
indeed, I don't want to ace everything. I am taking 4 courses this semester, one of which I don't care about enough to strive for the best grade, one of which is way too hard to aim that far, two of which I thought were achievable. and now I didn't achieve that. it feels different to set unrealistic goals and then never achieve them than to set very realistic ones and still fail, that's what I realized today
I am not a perfectionist. I used to be, years ago, and then I learned to set realistic goals. now I'm thinking, isn't perfectionism a kind of a coping mechanism? deep down you know your goals are impossible, so it's not really surprising when you fail. you are never satisfied, sure, but maybe it does feel more safe this way than to not know if you will be satisfied or disappointed. if that's the case then setting realistic goals is absolutely not the way to heal perfectionism
I neglected this blog like hell, sorry
I had a lot of work to do, that's kinda what happened. but I would like to go back to posting regularly, so maybe I could write about something people would want to see?
for now my ideas for posts include
more study tips
a quick intro to moduli functors, since a lot of sources are written in a way that requires advanced algebraic geometry. I could explain the basics using (almost) only commutative algebra
updates on my life and what I've been working on
books recommendations
interesting math problems I encountered recently
if you'd like to see any of that, let me know! and feel free to give me more suggestions in the comments
