Numbers everywhere

a, b - the Pythagorean Theorem

c - a scalar

d - differentiation

e - Euler's number

f, g, h - functions

i - the imaginary number

j - a quaternion

k - a scalar, but specifically when it's an integer

L - the Laplace transformation of a function

m, n - variables, but specifically when they're integers

O - Big O notation

p, q, r - Boolean variables

S - a set

t - parametric equations

U, V - more sets

a, b, n, m - Chinese Remainder Theorem. So I guess they are integers.

c - I agree, a scalar. Usually a small constant we use with Integrals. Usually written c_0 for me.

d - I would say indeed differenciation.

e - same, Euler's number.

f, g, h - definitely functions.

i, j, k - I was about to say "yeah of course imaginary number" for i but I also do associate it a lot with integers to iterate over

l - a small term of a loss function (this is very me, should be l_i^k or something)

o - little o notation

p - value between 0 and 1, a probability.

q, r - also integers, should be up there with a, b, m and n. I don't know it just makes sense that a = bq + r. But also q = 1-p. It really depends on my mood.

s - small sum.

t - a value between 0 and 1 in parametric equations indeed.

u, v - vectors

w - I'd say a sequence but I just don't use small w that much.

x, y, z - variables.

Uppercase time now! Now that when I say uppercase I usually write them in cursive. First, all the ones I don't associate with anything in uppercase unless they are sets: D, G, M, N, Q, R, Z.

I just realized most of them are sets: D, N, Q, R and Z are definitely specific sets. All decimal numbers (Not sure of the translation on this one but all numbers that can be written in the form a.10^n with a a rational number and n an integer), natural numbers, all rational numbers, real numbers and integers.

A - a set.

B - a ball. (Topology)

C - a convex space.

E - vector space

F - also a vector space, mainly subspace of E.

H - Hessian Matrix.

I - conveniently replaces an integral we were too lazy to simplify.

J - Jacobian matrix.

K - a closed set. (Topology again)

L - L is a loss function. (At some point it used to be all the linear functions in a set but I don't use those as frequently anymore 🥺)

O - Big O notation

P - probability.

S - I got lazy to write a sum I can't simplify.

T - this is definitely a variable I would associate with time but I'm not doing physics here.

U, V, W - sequences.

X - a set.

Y - a variable. (Think P(Y=y | X=x) here)

Year-end wrap up challenge — [Day 30/30]

👟 steps: 510 / 3000 📚 productivity: 7h / 1h ✅ 📝 prompt of the day: ✅

And we're done!!! Holy shit we're actually officially almost done with 2025. It's crazy to think about.

Goal updates:

I wasn't able to complete my step goal a lot of the days because winter flared up my symptoms so so bad, but I did my best on days that I could! I tried when I have the energy, and although it doesn't feel enough, I'm choosing to believe that it is. I didn't give up on days when I could have walked, and got my steps in. And on days that I couldn't walk, I didn't force myself and listened to my body's needs and took the rest that I very much needed, i think that's what matters. I am happy that I came to the mindset where I don't have to feel guilty for listening to my body anymore.

I was productive almost everyday because half the month was exam season, so i think that automatically checks out lmao. The amount of all nighters tho jeez... I can't wait to be done with exams.

I answered the prompt of the day everyday in my journal and it helped me reflect a lot on the tiniest things, and it made me feel like i accomplished a few things this year :)

Overall, i think I did okay this month, and i feel ready for next year. Even though there are a lot of things that I'm slightly dreading, i know that I am prepared to tackle whatever comes my way. I realised that I went through a lot this year but I survived it all, so this is proof that I can do the same next year.

Here's to us!

Prompt of the day: my word for the new year is...

Faith. Because next year there are a few things that will happen in my life that can alter the course of my life in so many ways, and I need to have faith that it will be a positive change. Faith has helped me a lot in situations where i felt helpless and was close to giving up, so I will take the same mindset to the next year. I have faith that everything that happens has a silver lining.

Hello my fellow writers and students! I have an etsy shop where I make writing and studying resources. After an incident at work earlier this year I made the big decision to go part time and start studying my masters degree - it was always something I've wanted to do and after how bad my mental health got this year, I needed to go and do something that made me happy. But this means a cut in my wages as well. I started an Etsy shop as something to focus on and keep me going and now also as a little extra income for whilst I am studying. So if you're interested, please check it out. Or if you could support just by favouriting some items or sharing this post that would be a massive help too because I don't expect everyone to go and buy things, life is expensive. Thank you all for your support! Here are just some of my products!

I just started my React course, and my first project was a static page for a digital business card. Sometimes I feel very insecure about my pace when learning a new skill. There will always be someone better and faster at learning than we are, and while that takes some pressure off, it also makes me anxious about how far I’m capable of going.

And then, at some point, the people who left started coming back.

It was the children first. The March of Dimes and Saint Jude set up programs and my town would do spaghetti fundraisers and raffles and meal trains to support the family and send the child and one parent to a hospital in the city — and the children came home. Their hair grew back. They went back to school. We were all trained to think of them as the angelic lost and they were turning into asshole teens right in front of our eyes. What a miracle, what a gift, how lucky we are that the odds for several children are in our favor!

Adults started leaving for a specific program to treat their specific cancer at a specific hospital or a specific research group. They’d stay in that city for 6-12 months and then they’d come home. We fully expected that they were still dying — or they’d gotten one of the good cancers. What a gift this year is for them, we’d think. How lucky they are to be strong enough to ski and swim and run. And then they didn’t stop — two decades later they haven’t stopped. Not all of them, but most of them.

We bought those extra hours and months and years. We paid for time with our taxes. Scientists found ways for treatment to be less terrible, less poisonous, and a thousand times more effective.

And now, when a friend was diagnosed, the five year survival odds were 95%. My friend is alive, nearly five years later. Those kids who miraculously survived are alive. The adults who beat the odds are still alive. I grew up in a place small enough that you can see the losses. And now, the hospital in my tiny hometown can effectively treat many cancers. Most people don’t have to go away for treatment. They said we could never cure cancer, as it were, but we can cure a lot of cancers. We can diagnose a lot of cancers early enough to treat them with minor interventions. We can prevent a lot of cancers.

We could keep doing that. We could continue to fund research into other heartbreaks — into Long Covid and MCAS and psych meds with fewer side effects and dementia treatments. We could buy months and years, alleviate the suffering of our neighbors. That is what funding health research buys: time and ease.
