Be The Academic You've Always Dreamt Of Being. Stay Up Till 3 A.m. With Your Paperbacks Scattered On

told my project partner all she had to do was write the sql script following the logical schema i drew so carefully

this is what she came up with 🤦‍♀️:

where are the foreign keys, where are the semicolons, and why the hell are there STRINGs in an sql script

do i yeet her out of the window or do i yeet myself out of the window

Did I daydream this, or was there a website for writers with like. A ridiculous quantity of descriptive aid. Like I remember clicking on " inside a cinema " or something like that. Then, BAM. Here's a list of smell and sounds. I can't remember it for the life of me, but if someone else can, help a bitch out <3

winter dark academia

- waking up to cold mornings and condensation on your windows

- brewing a cup of hot coffee while reading a book

- wearing cozy sweaters and cardigans to stay warm

- draping your favorite long coat over your shoulders to create a mysterious silhouette

- stepping through heavy, packed snow as you walk to your morning class

- watching the glistening trees, pausing your podcast to admire them in their full glory

- combing your fingers through your hair to remove the falling snowflakes

- sipping hot chocolate in front of a roaring fire, turning the pages in your book leisurely

- stringing fairy lights to brighten up a dark room

- practicing your instrument in the evening, pretending to play at night - but the sun just sets early, but that’s not important

- relishing the long, dark hours to keep focused on your work

- listening to the quiet tones of claire de lune as you scribble through your essay

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!

school started for me this past tuesday so im hoping to post a lot unlike last semester! these are some small chem notes from unit 1 that my cat completely wrinkled...

it rocks you know what 17776 is, I know so few people who’ve read or interacted with it at all and it remains one of my all time favorite pieces of writing to date

i am very fond of it :)

dearest followers go read 17776 if you haven't already. probably best experienced on desktop.
