I Am Not Taking Questions At This Time

[poem text: listen, nine hundred and fifty years before jesus was a child shaking willow leaves out of his tangled curls, the author of the song of solomon wrote: behold, you are beautiful; your eyes are doves.

what i’m trying to say is that, in this universe which sculpted itself from a baptism of fire, i am the moon swept up by your tenderness. you’ve got me dreaming foreign words: gravity, ellipsis, perigee, until all i can think about is becoming anchored into orbit around the saltwater-green landscape of your laughter.

listen, plato of ancient greece wrote that the souls we each have now are only halves. that in a frenzy of blood zeus severed us from each other, so we rely on the blind tugging of our hearts. you say my name and i want to knit my bones into your bones, smooth away the boundaries of our heartbeats.

what i’m trying to say is that if the temperature inside those wild pockets of interstellar dust hits right near absolute zero, carbon monoxide and dihydrogen molecules condense together in the dark nebula to form stars. if you’re ready, i want to make you shiver like that. /end poem text.]

How to Really Comprehend a Scientific Paper

**credit to my research advisor, she’s an amazing mentor and I aspire to be just like her someday :)

Read the abstract. Write down what the paper says it is going to be about.

Read the introduction. Write down what the paper says it is looking to accomplish and how.

Read the conclusion. Write down what the paper actually did accomplish.

Go through and find all the pictures, graphs, or diagrams. Write notes explaining these images to yourself.

Read the whole paper start to finish. Write a summary of the paper as though you are explaining it to a layperson, and then another summary as though you are explaining it to a colleague.

Throughout all of the above steps:

If there are words you don’t know google them and write down the definitions

If the paper defines a formula, law, variable, etc in a certain way write that down

If there are references to or recommendations of other literature write those down. After the last step if there’s anything you’re uncertain about or would like more information on look to that list for further reading

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! 

Duolingo Spanish Vocab: Science

Duolingo recently rolled out a new feature that includes a dynamic list of vocabulary terms as new lessons are completed. I love this feature and its way of keeping track of words and phrases that are getting rusty, but I want a way to categorize the terms based on subject. Until a feature like that rolls out (if ever), I’m going to start posting subject- and lesson-specific vocabulary lists for Duolingo Spanish.

hold on a fucking second. delaware is a state?? i thought it was a river? or is the river more important than the state? why don't i know this? (i should mention i don't like in america, i'm just confused)

there is delaware (state) and delaware (river) 

both are equally strange

the state is a tiny little cryptid thing

the rive is a monster that spans new york, pennsylvania, new jersey and delaware. also washington crossed it once and that was like kinda a big deal i guess. like crossing the rubicon in rome.

the state tries to me more important with its “im the first state!!!” bs (seriously its even on the fucking license plates) but we all know. its the river.
