Hey If U Like The Ocean Look At This Its Rly Cool I Think

You know what. I’m starting a new aesthetic, population me.

Romantic Science, AKA Dark Academia for STEM people.

Thrifting a lab coat and embroidering it with your initials and a little insignia, whose significance is known to you and your lab partner only

Watching The Theory of Everything and The Imitation Game and Hidden Figures and basically every movie about historical scientists and mathematicians you can find

Decorating your desk with old slide rules and vintage lab equipment. Your prize possession is a set of vintage lenses you found at a thrift store

Wanting an articulated human skeleton far, far too much

Getting a set of (brand new, NOT thrifted, be safe ppl) beakers to drink from, and putting them directly onto your stovetop to boil water for tea or coffee, because borosilicate glass can survive anything.

Secretly relating far too much to Henry Jekyll and Victor Frankenstein, because you too want to do a gay little science experiment that challenges god.

Thunderstorms and late nights in the lab, the light of the Bunsen burner glistening off of your flasks and scribbled chalkboard equations

Papering your walls with vintage scientific diagrams; even if you know that our understanding of the world has evolved since they were made, looking back at scientific history is amazing

Writing code late at night and feeling, in some metaphysical way, as though Ada Lovelace herself is with you in spirit

Being far, FAR too obsessed with the concept of emergent ai sentience and how it has the potential to be Frankenstein irl

Looking through a telescope on clear nights, whispering the names of the constellations and stars, painting a star chart on your ceiling in a burst of creative inspiration

Collecting and mounting samples from everywhere you can think of to pore over in an antique microscope

Bringing a field journal wherever you go, learning how to draw and label botanical samples, preserving plants and flowers for study later

Dreaming of what undiscovered mysteries lie in the deepest depths of the sea, feeling the thrill of discovery whenever you learn about a new species and one day hoping to discover one yourself

Just. Romanticise STEM.

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!

spring journal prompts

things to get rid of, things to gain

something you want to learn

go out and press some spring flowers, write how each makes you feel

write what each colour of the rainbow means to you

what does birdsong make you think of?

do some mental spring cleaning; dump old thought patterns that no longer serve you

set a "spring goal" for yourself

watch the sun rise, write about it

design your ideal ecosystem

what are you looking forward to?

go outside. what do you hear? how does that make you feel?

New Zealand 2022: Christchurch

Christchurch was so much smaller and quieter than I had expected, especially having lived in Melbourne for years. It felt very much to me like a big town than a city, resembling Ballarat or Bendigo in Australia, but with its unique charms, of course.

We visited the Tannery (Yes I've posted this spread inspired by the vibes there before, so this is a re-post), a quaint shopping area with beautiful boutiques and vintage shops. Most of the time however, we were around the Riverside Market, trying the local produce or just enjoying the vibes of the place.

Christchurch Botanic Gardens was definitely a highlight, with flowers I've never seen before, massive trees, beautiful water features and charming rose gardens. I enjoyed Christchurch Botanic Gardens more than the one in Auckland, although the weather probably played a big part! The curated experience of the two gardens were very different though, so it's probably not a fair comparison. But I'd definitely recommend all three areas to anyone visiting Christchurch.

math help bc i can’t watch ya’ll suffer anymore

I’m in my fourth year of engineering school and I didn’t get here without lots of outside help bc assigned math textbooks are lame and confusing and professors/teachers are more worried about feeling superior to bunch of groggy teenagers than actually teaching.

I have personally used all of these websites without receiving any security warnings from Bitdefender TrafficLight or AdGuard AdBlocker. They are all either completely free or have a free version that isn’t shit.

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
