Oooh, I tried this method in first year physics too! It was very effective, since I got fine details from the pre-reading, which was supplemented during the lecture! This method worked fantastic (as long as I kept a routine)! Good luck with it!

✨2/30 days of productivity✨

started taking notes on QM today. i think i figured out how i want to take notes this year (at least in this course); reading and taking a bit of notes pre lecture and then i made a column of space for adding things during the lecture so i don’t have to write everything down during the lecture, only the things i missed in my notes! this way i can focus more on listening and understanding during the lecture, i damn hope it works lol

Sometimes my work feels more academic than my studies

Bujo trackers for getting your shit together

I typed a super long ass post about this and the accidentally deleted it before saving and now I’m lying on the cold hard ground

Yohoo potatoes, I’m back with another *whips out a megaphone out of nowhere* “long ass post” (is that my patent now?) for you guys! This one could help out with your studyjo/bujo (if you don’t know what a studyjo is don’t worry I’ll link it later) and organising that potato life to make the most of it!

Why should I use a bullet journal?

You’s a student

You’s busy

You’s got life you can’t handle sometimes

You will 120% forget about tat assignment deadline unless you’re reminded of it

You get to laugh at your past self after 20 years or so

It’s therapeutic and all that ish

You’ll like it because it’s being productive while actually kinda procrastinating (aren’t we bosses at procrastinating?)

Memories :)

Bolded ones are the trackers I am using and are potato proofed

1. Study related :

SYLLABUS TRACKER : finals can go a little smoothly if you have it all at one place

PROJECT PLANNER/TRACKER : deadlines + road map of how you’re gonna ace that project

STUDY SESSION TRACKER : time, date, subject and rating your session

GOALS TRACKER : realistic ones, like score 75% or more in this test, or master the concept of integration (ughh). Philosophy ones come later ;)

EXAM PLANNER : plan something for each day a week before your exam and see the magic

For solving based subjects :

PROBLEM TRACKER : shade the box every day you solve “x” number of sums

FORMULA QUIZ : the most difficult ones which you’ll never remember unless they’re carved on your ribs

Theory based subjects :

CONCEPT PLANNER : shade the box every day you learn “x” concept nicely

RANDOM CONCEPTS TO REVISE LIST : super helpful when you’re procrastinating and don’t know what to study - refer to this list and do you ish

READINGS LIST : shade the box every day when you read “x” number of paragraphs from textbooks/notes/books

Language based subjects :

WORD OF THE DAY PAGE : one word every day

PASSAGE OF THE MONTH : sort of like a journal but in your target language

FAVOURITE SENTENCES/QUOTES /SONGS/ETC IN *TARGET LANGUAGE* PAGE - similar to a journal thing, make it all aesthetic and cool so you’ll want to fill it in more

2. Entertainment related stuff :

MOVIES WATCHED SO FAR - all the movies, maybe stash a ticket or smthn?

MOVIE OF THE MONTH - can pick any one tbh

APPRECIATION PAGE FOR *FAV ACTOR/ACTRESS* - can you guess who’s appreciated by this potato?

SONG OF THE MONTH - only pick one and trust me that is very difficult

APPRECIATION PAGE FOR *FAV SINGER* - guess mine again?

PLAYLIST OF THE MONTH - best songs only

MIX TAPE FOR *FAV PERSON* - you can actually even make a real one and give it to someone you really like ;)

SERIES TRACKER - episodes/seasons number, shade the box as you finish it

REVIEW PAGE - review some movies/TV show you just saw

FAVOURITE MOVIE QUOTES PAGE - “you’re a wizard, Harry”

3. Mind related stuff :

QUOTES PAGE - motivational, sentimental stuff

MEDITATION TRACKER - this potato might try it

CROSSWORD TRACKER - shade the box every time you successfully solve an entire crossword/puzzle

RIDDLE TRACKER - shade the box every day if you solved 1 riddle

CREATIVITY PAGE - doodles, ugly poetry, cringy picky up limes, whatever floats your goat

BRAIN DUMP PAGE - every single thing on your mind transferred on this page. Suggested before sleeping so that you’re light headed and stress-free

IDEAS ORGANISER PAGE - give form to those abstract plots and connect all ideas to make a bigger one

PERSONAL PROJECT PLANNER - like maybe that book you always wanted to write

LIFE IN PIXELS - mad, sad or smad?

4. Health related stuff :

EXERCISE TRACKER - shade the box every day if you did “x” duration/amount of exercise

FOOD TRACKER - keep record of what junk you munched on today and try to avoid it sometimes

WATER TRACKER - ughh so important

CARBS TRACKER - kill a puppy next time you overeat

MOOD TRACKER - graphs look fancy tbh

ROLE MODEL’S PAGE - everything hermione granger does/says

5. Money related stuff :

BUDGET TRACKER - note down every little thing you spent on, figure out where you can save up

SAVINGS TRACKER - fill that little jar and buy those pens you always wanted to

Aaand that’s about it for now! I’ll be back with another long ass post so have fun bullet journaling till then!

Feel free to hmu if you aren’t clear about how to use a certain tracker!

Propagation of Error

When I first started in physics, I was utterly clueless about propagating error. After three years of college, I have a better grasp of it and feel more comfortable using it in the lab. Have a look if you’re having trouble with error propagation!

Error and Uncertainty

Error: an unknown quantity in the realm of the state of nature

Uncertainty: a parameter in the realm of our state of knowledge about nature

Type A uncertainty: statistical in nature (an example of this would be if you were launching an object 15 times and recorded each distance)

Type B uncertainty: not statistical in nature (an example of this would be a digital reading on a scale - no matter how many times you put the same object on the scale, you will get the same reading)

Random vs Systematic Error

Random Error

environmental fluctuations

equipment noise

natural processes

Systematic Error

environment: fixed beyond a relevant parameter

measurement technique: assumptions, experimenter bias

equipment with an offset or using equipment beyond its limits

uninformed choices

You can reduce random error by taking more measurements.

You can reduce systematic error through thoroughness, properly calibrating equipment, reading manuals, and ensuring reproducibility. 

Basic Error Propagation

This is the standard equation for error propagation:

This represents the uncertainty in the measurement of some value x. Suppose you are measuring this value based on this equation:

You took three measurements, a, b, and c, and plugged them into this equation to get x. However, there is some uncertainty associated with each of these three values. Let’s say you measured a on a scale, b on an oscilloscope, and c with a ruler. There is uncertainty associated with all of those measurements. When you’re reading the scale, you read it as 15.45g. Let’s assume there is an uncertainty of 0.01g in that reading. Similarly, you read your oscilloscope to be 3V, and there is an uncertainty of 0.05V. You read your ruler to be 3.45cm, and there is an uncertainty of 0.05cm. We now have our uncertainties for the three values:

a = 15.45g +/- 0.01g

b = 3V +/- 0.05V

c = 3.45cm +/- 0.05cm

The other aspect of the uncertainty equation is taking the partial derivative. Those are the dx/da and dx/db parts of the equation. We will take the partial with respect of each term. 

The partial derivative of the equation for x with respect to a is 2a2

The partial derivative of the equation for x with respect to b is 2

The partial derivative of the equation for x with respect to c is 4.5

Now, we can plug into our equation:

Your uncertainty in your measurement for x is +/- 22.86.

I hoped this helped you if you’re struggling with uncertainty! 

literally though if you feel like your life is slipping through your fingers and every day goes too fast… try doing hard things, not just taking the easy route, like reading and making art and exercising and cooking a meal from scratch and journaling, doing these things without distraction, without being absorbed on a screen… the time will stretch and you’ll be reminded that life is long and beautiful if you make it so.

100 days of productivity

starting 25th October 2023 ending 2nd February 2024

Rules

Success or failure -- just show up

No #ZeroDays -- No matter how hard it feels, do a little thing, a bare minimum. Don't let any day become a zero day

Do at least one PhD-related task everyday

Read a journal article everyday. Skim, AIC, full workout - anything

Weekends are excluded, but counted -- because rest is productive

Learn & practice mindfulness

Take two pictures everyday to represent the day (post them here)

Accountability

Daily update of task list here. Perfection is the enemy of done. So don't overthink, just post - even if it feels half-baked.

-----

I’m currently in the final quarter of my PhD. I feel quite demotivated and I find it hard to gain momentum. So I thought I'll take up an accountability challenge to help me stay motivated and eventually build a routine.

If you are already doing a 100 days of productivity challenge, or would like to take on one, please do comment/like this post. I'd love to have some company and inspiration! Please help me find similar accounts! <3
