COVID is slowly becoming a "third world" disease. While first world countries are hoarding vaccines, having doses for populations many times their size, third world countries can't get any because pharma companies want to sell to the first world countries first. Even then, first world countries will receive them first. While rich countries recover from COVID, they will forget about the pandemic while many other countries live the absolute worst moment of the pandemic without being able to vaccinate their population.
Watch also when some first world countries finish vaccinating their populations, they will turn to third world countries and "donate" or sell surplus vaccines. People in these countries will go "Oh how sweet! The government is donating vaccines to the poorer countries <3" when it was their hoarding that led to many, many third world citizens dying before they could even get vaccinated in the first place.
This is not a bullshit useless change dot org petition by the way this is an actual thing with legal consequences. If this petition gets to a million signatures, the european commission HAS to examine it.

theory - Supersymmetry by Arcade Fire (alternatively: Symmetry by Wye Oak)
âWhen you ask what are electrons and protons I ought to answer that this question is not a profitable one to ask and does not really have a meaning. The important thing about electrons and protons is not what they are but how they behave, how they move. I can describe the situation by comparing it to the game of chess. In chess, we have various chessmen, kings, knights, pawns and so on. If you ask what chessman is, the answer would be that it is a piece of wood, or a piece of ivory, or perhaps just a sign written on paper, or anything whatever. It does not matter. Each chessman has a characteristic way of moving and this is all that matters about it. The whole game of chess follows from this way of moving the various chessmen.â â Paul A. M. Dirac
having competitions with your friends to see who can write the best Greek characters. staying up late working on code. rewarding yourself by using a piece of hagoromo chalk on the next problem, enjoying its smooth glide across the blackboard. breaking everything you touch in a physics lab. admiring the beautiful symmetry in and of the universe.
experiment- Default by Django Django or Glamorous Damage by GUM
âMeasure what is measurable, and make measurable what is not so.â â Galileo Galilei
clean data with good statistics and high precision is manna from the gods. the image of oscilloscopes with fountains of wires spilling from them fills you with peace. spending extra time in the lab, not due to pressure from your PI, but because youâre so absorbed in your project. calling the peaks in your spectrum âlittle guysâ and âbig guysâ. the feeling of finally taking usable measurements. you enjoy error propagation too much.
nuclear - Physics by Wild Front
When we have found how the nucleus of atoms is built up we shall have found the greatest secret of allâexcept life. We shall have found the basis of everythingâof the earth we walk on, of the air we breathe, of the sunshine, of our physical body itself, of everything in the world, however great or however smallâexcept life. â Ernest Rutherford
repeatedly dispelling the notion that your work relates to warheads or power generation. absolutely losing it over football-shaped nuclei. having another emotional breakdown because ROOT decided it didnât like the way you write in C++. all-nighters spent in the control room of the accelerator (during your only experiment this year!), consuming frightful amounts of caffeine and laughing deliriously with your group members. going home afterwards, sleeping deeply, then returning to the lab the next day to do it all over. respectfully simping for Maria Goeppert Mayer.Â
astro/cosmology - Planets and Stars by Pavvla (or Dark Waves by Robot Koch)
âI have loved the stars too fondly to be fearful of the night.â â Galileo Galilei
regularly stumbling as you walk home because youâre squinting at the barely visible Pleiades. your version of asmr is listening to the blip of a neutron star merger detected by LIGO. attending chilly community telescope nights in the hills outside your city, inviting children come up and peer into the refractor that youâve angled at Jupiter. fervently explaining how we are the byproducts of stellar nucleosynthesis at a party.Â
particle - Higgs Boson Blues by Nick Cave & the Bad Seeds
Tapestries are made by many artisans working together. The contributions of separate workers cannot be discerned in the completed work, and the loose and false threads have been covered over. So it is in our picture of particle physics.â â Sheldon L. Glashow
dreaming of discovering a force carrier for gravity. or measuring neutrino mass. or observing dark matter. you get indignant when people claim your work is just fanfiction of the standard model, but only because itâs true. staying up late into the night thinking about the weirdness of discretized time and space. carrying your worn copy of the PDG particle physics booklet with you, just in case. hoping for accessible energy levels in the experiment youâre cooking up.
condensed matter - Quantum Physics by Ruby Waters (also Polychromatic by Castelle)
âNo matter what you look at, if you look at it closely enough, you are involved in the entire universe.â â Michael Faraday
not only describing how matter behaves, but manipulating its behavior to suit your needs. teasing your nuclear friends about the practical applications of their research. the simultaneous mundanity and excitement surrounding the materials you study. setting up a miniature lab space in your kitchen and embracing the strange looks from your household. randomly finding transistors in the bottom of your bag or tucked into a pocket. being an absolute fanatic about microcontrollers, jerry-rigging pieces of lab equipment with them on the cheap.
please donât take this as a prescription for your behavior; being a physicist isnât about performing for others. itâs about gaining and creating new knowledge surrounding the behavior of the universe. if you enjoy that and want to immerse yourself in it, all the better :)
Right now, Iâm sifting through 50+ applications for a new entry-level position. Hereâs some advice from the person who will actually be looking at your CV/resume and cover letter:
âYou must include a cover letterâ does not mean âwrite a single line about why you want this positionâ. If you canât be bothered to write at least one actual paragraphs about why you want this job, I canât be bothered to read your CV.
Donât bother including a list of your interests if all you can think of is âsocialising with friendsâ and âlistening to musicâ. Everyone likes those things. Unless you can explain why the stuff you do enriches you as a person and a candidate (e.g. playing an instrument or a sport shows dedication and discipline) then I honestly donât care how you spend your time. I wonât be looking at your CV thinking âhuh, they havenât included their interests, they must have noneâ, Iâm just looking for what you have included.
Even if you apply online, I can see the filename you used for your CV. Filenames that donât include YOUR name are annoying. Filenames like âCV - mediaâ tell me that youâve got several CVs you send off depending on the kind of job advertised and that you probably didnât tailor it for this position. â[Full name] CVâ is best.
USE. A. PDF. All the meta information, including how long you worked on it, when you created it, times, etc, is right there in a Word doc. PDFs are far more professional looking and clean and mean that I canât make any (unconscious or not) decisions about you based on information about the file.
I donât care what the duties in your previous unrelated jobs were unless you can tell me why theyâre useful to this job. If you worked in a shop, and youâre applying for an office job which involves talking to lots of people, donât give me a list of stuff you did, write a sentence about how much you enjoyed working in a team to help everyone you interacted with and did your best to make them leave the shop with a smile. I want to know what makes you happy in a job, because I want you to be happy within the job Iâm advertising.
Does the application pack say who youâll be reporting to? Can you find their name on the company website? Address your application to them. Itâs super easy and shows that you give enough of a shit to google something. 95% of people donât do this.
Tell me who you are. Tell me what makes you want to get up in the morning and go to work and feel fulfilled. Tell me what youâre looking for, not just what you think Iâm looking for.
I will skim your CV. If you have a bunch of bullet points, make every one of them count. Make the first one the best one. If itâs not interesting to you, itâs probably not interesting to me. Iâm overworked and tired. Make my job easy.
âI work well in a team or individuallyâ okay cool, you and everyone else. If the job means youâll be part of a big team, talk about how much you love teamwork and how collaborating with people is the best way to solve problems. If the job requires lots of independence, talk about how you are great at taking direction and running with it, and how you have the confidence to follow your own ideas and seek out the insight of others when necessary. I am profoundly uninterested in cookie-cutter statements. I want to know how you actually work, not how a teacher once told you you should work.
For an entry-level role, tell me how youâre looking forward to growing and developing and learning as much as you can. I will hire genuine enthusiasm and drive over cherry-picked skills any day. You can teach someone to use Excel, but you canât teach someone to give a shit. It makes a real difference.
This is my advice for small, independent orgs like charities, etc. We usually donât go through agencies, and the person reading through the applications is usually the person who will manage you, so it helps if you can give them a real sense of who you are and how youâll grab hold of that entry level position and give it all youâve got. This stuff might not apply to big companies with actual HR departments - itâs up to you to figure out the culture and what theyâre looking for and mirror it. Do they use buzzwords? Use the same buzzwords! Do they write in a friendly, informal way? Do the same! And remember, 95% of job hunting (beyond who you know and flat-out nepotism, ugh) is luck. If you keep getting rejected, itâs not because you suck. You might just need a different approach, or it might just take the right pair of eyes landing on your CV.
And if you get rejected, itâs worthwhile asking why. Youâve already been rejected, the worst has already happened, thereâs really nothing bad that can come out of you asking them for some constructive feedback (politely, informally, âif it isnât too much troubleâ). Pretty much all of us have been hopeless jobseekers at one point or another. We know itâs shitty and hard and soul-crushing. Friendliness goes a long way. Even if itâs just one line like âyour cover letter wasnât inspiring" at least you know where to start.
And seriously, if you have any friends that do any kind of hiring or have any involvement with that side of things, ask them to look at your CV with a big red pen and brutal honesty. I do this all the time, and the most important thing I do is making it so their CV doesnât read exactly like that of every other person who took the same âhow-to-get-a-jobâ class in school. If your CV has a paragraph that starts with something like âI am a highly motivated and punctual individual whoââ then oh my god I AM ALREADY ASLEEP.
This is the first good resume advice post Iâve seen on this site. Much better advice than the âlists of active verbs to useâ and âhere are resume templatesâ. Follow this advice.
Astrophysics Tools for Research and Data Analysis!
Hi guys, I've been wanting to make a post about how to use various data analysis and research tools for astrophysics, because I had a pretty hands-off supervisor and had to figure things out myself, with my research partner, or by asking academics I knew (like my friend Will). So, this is going to be a quick rundown of how to find data catalogues, download them, and analyse them (using Topcat), and then also how to use search tools like the SDSS and SIMBAD. There is not going to be anything in here about finding research papers, or search terms for google scholar, because firstly I am a noob with those and secondly because there are already beautiful, detailed posts about that. This is specifically for when you want to get some data, analyse it, and search for sources in other catalogues.
First up: how do I find my data?
Well, we use VizieR.
This is a nice, sexy, unintuitive website where you can search for various data catalogues and download them. For this, you will probably want to already know what catalogue you want by the time you get there, so I would recommend reading around. The simplest way to do that is to search on google: "[instrument name] [source type] catalogue" and read whatever papers come up. For example, you might be looking in radio, at the FIRST survey, and decide you want to look at blazar data. So you should google "FIRST radio survey blazar catalogue" and see what comes up. You are going to want to eventually know as much as possible about your catalogue's selection criteria, and what it's specs are, but for now you can start by just skimming the paper and searching it up in VizieR.
Your next step is actually finding the catalogues.
VizieR looks like this, and you should be able to find your survey by typing in its name into the little search box you see here. Next, when you have searched and been able to find your survey, clicking on it should lead you to a page like this one:
The important thing here, is to switch some stuff under the preferences heading. If you're using Topcat, you want to switch the HTML table to a VOTable, and you want to switch the maximum number of rows from 50 to unlimited. This will allow you to download the full catalogue. I suspect that if you are using Python or RStudio for data analysis, you probably want to keep it in the HTML format.
So once you have your preferences looking like this, you click the "Submit" button in the bottom right of the page, and the table should start downloading.
Great! Now you have your data! How to analyse it though?
Use Topcat!
Topcat is a piece of software developed by Mark Taylor at Nottingham University, purely for the purpose of astrophysics data analysis. As a result of this, it has some really useful features and is in general much easier to use than writing your own code in, for example, Python.
Once you download Topcat, it might take some effort to get your computer to open it, because it is not by a verified developer. That being said, it is safe, so do what you can to get it open.
Loading it up, you should find yourself looking at a grey control panel. On the left will be a blank list of tables, and next to that will be a blank space, and above all of that there will be a toolbar. The first thing you want to do is load your table into Topcat.
So, to do that, you want to click on the left-most button on the toolbar, the one shaped like a file. There, you click "system browser" and go through your files and find the VOTable you downloaded from VizieR (unless you renamed it, it will be called VOTable). This will load your data in. Now, your table list should include your VOTable data. When you have this selected in the main panel, you can use different toolbar buttons to either look at the table itself or visualise the data. Full disclosure, I am not that seasoned with using Topcat's most advanced features, so if you need to know how to use them, I would recommend checking out Mark Taylor's video tutorial here.
For the basics, the first 3 buttons in the toolbar are used to import and export data, the next 6 buttons are used to look at the table, and the following 6 buttons are used to represent the data in graphs. After that, the next 3 buttons are used to: 1- match tables and combine them to make a new table, 2- query remote databases, 3- crossmatch sources against remote tables based on their sky position.
The most important buttons are the 4th one from the left, the 11th button along, and probably the one used for matching tables (it looks like a pair of matchsticks. Get it?). The 4th one allows you to look at and search through your tables, and the 11th one allows you to represent your data on a non-bar graph.
I won't go into a lot of depth here about how to use these 2-3 really important buttons, but if you have questions you can message me and I will try to answer!
Finally, what do you do if you find a source you think you want to investigate further, how do you find out more information about it?
Use SIMBAD, SDSS and other search tools!!
This is my final bit, so hang in there.
There are really convenient search tools for you to look up your sources in, and they all seemingly provide different things. SIMBAD has a bunch of different catalogues loaded into it, including transient catalogues, and you can input the location of your source, and it will either tell you what it thinks it is, or it will tell you what is nearby to your source's location. So firstly, you can find SIMBAD here, and when you go to that link, you should see this:
There are different query methods. You can search by coordinates, criteria, or identifier, so if you have the information for where the source is or what it's called, it should be not too hard to find what you're looking for.
I'm starting with an identifier query for M31, the Andromeda galaxy, just to show you how it works for a well-known, well-defined source:
You can see that SIMBAD has given me data about this source, including a little view of it on the sky, and what it's called and what it is. It has some information about the object's speed and its magnitude in different bands. Andromeda is probably one of the most observed galaxies ever, so there is a lot of information here.
Searching for a more obscure source yields fewer results, with less information about the sources and less certainty that the sources have been correctly identified.
This was a coordinate search for a source I have looked at in WISE data, and it says that there is not an accepted exact match for this source, but that the closest registered object is a white dwarf candidate 0.31 arcseconds away. I can click on that candidate and be provided with a page of information like I was for Andromeda, but with less concrete data. The source I'm searching for is actually an AGN candidate, but it is so un-researched that it simply doesn't show up as anything useful.
Our next thing is the SDSS, the sloan digital sky survey. This contains a lot of spectra for different sources, and does not tend to tell you about nearby sources. For the SDSS, you have to know the RA and DEC of your source in degrees, which is a little annoying. You can find them usually by looking in your table on Topcat.
The SDSS honestly looks like a kid's dress up game from mathgames dot com, but it's an actual serious tool. Sigh. The most important thing is to NOT USE this page at all, and to instead click the little "explore" link under the DR16 logo. That should look like this:
As you can see, this is a bunch of information about the source it automatically highlighted. It's useful info, but you probably don't want to know about this source. You probably want to find your own source here. So, to do that you have to click "search" on the left hand side, which should add these search boxes to the top of the page:
Here, you put in the RA and Dec, and then press the "Go" button next to it. This should give you an info page, like the one above, but with YOUR source. Otherwise, it will give you an error message saying it doesn't know where your source is and it doesn't have a record of it. That's ok, it doesn't mean it doesn't exist, but it could mean that this source is not documented in other large catalogues.

i can not and i mean i can not stress this enough⌠make a bibliography as you do your research. i mean, make a fully formed, correctly cited bibliography as you work. just do it. i know i know youâre being lazy or you hate making citations or youâll just get to it later or you donât want to get distracted etc etc etc
whatever your reasons just make the fuckin bibliography
and while im at it⌠put the footnotes in properly as you are writing. just⌠do it. for future you. please. for your sanity. do it.
hello everyone! due to requests, iâll be sharing a couple of my notion templates! these will include: my weekly agenda, my module schedule, my reading tracker, my podcast track and my movies/tv shows tracker.Â
these templates are all stripped-down versions of what i use daily and they can be customized to however you like them to look. once youâve clicked on the links, they will direct you to a copy of my template, which you can duplicate into your own personal notion workspace. thank you all for showing so much interest in my notion setup and i hope you enjoy using these!Â
mental health tips i wish iâd been given before starting university
trying is much more important than succeeding
10 minutes of studying > not studying at all
being a college student is more than academics. itâs also learning how to enjoy your own company, learning and occasionally screwing up meals, wandering outside campus like a tourist, questioning your ideals and presuppositions, discovering new talents and skills for the hell of it, and SOÂ much more. if you feel burnt out in one dimension of college life, thatâs a sign to spend some time relishing in another dimension.
if you need more time, take a deep breath and shoot that email to your professor/TA asking for an extension. at worst, they say no. and donât stress over properly explaining yourself/your situation. hell, just email them: âHi, Professor. I need your help. Sincerely, y/n.â all it takes is that one initial reach out and the rest will follow.
failure does not reflect character. read that again. remind yourself as often as you see fit because at one point or another, you will feel like youâve failed. itâs growing pains. once youâve accepted that, learn to view any setbacks as a hint that you need to try a new method/approach. didnât do well on that math quiz? donât beat yourself up over itâinstead, regroup with yourself and see which metaphorical gear got stuck in your personal learning process machine. for instance, maybe you used flash cards and that wasnât really your style. act like a detective, not a bully.
THERE IS NO NORMAL TIMELINE FOR YOUR COLLEGE CAREER(!!!!!!). a lot of people need more than 4 years, a lot of people need 4 years, and a lot of people need less than 4 years. and every single one of those timelines are valid. the worst thing you could do is squeeze the living hell out of yourself into some rigid schedule that is incompatible with who you are and how you learn. trust me when i say u will find yourself doing the best work when u do it at YOUR pace.

ai spent so long on setting up notion for 2021 but iâm satisfied and i think i found something that finally works for me - remember that when it comes to productivity itâs up to you to find what works and what doesnât, i started using notion almost a year ago and until now never found a set up that worked for me.
let me know if youâre interested in using this template and I will find a way to share it with you!
home
i use this just to have all of my pages accessible when i open up notion - i also put everything under a category to make it easier to access during the day.
goals, journal, reviewÂ
goals - i use this page to track my long term goals, both divided in personal and school related.Â
journal - i use this page as my personal journal, a brain dump, a place to collect ideas, i also made some tags to categorize if iâm talking about something personal, school or if itâs an idea or a dream.Â
review -Â since the journal is something more specific for the day, i like to keep track how my month went.
agenda.Â
here i have my monthly agenda, with goals and dates to remember - also i used a widget that connects to my google calendar so i can see whatâs next and what i have to do. beneath i have my weekly agenda that i use to keep track of the task that i have to do daily.
hdemia, subjects, study plan.Â
hdemia - this my main academic page where i keep track of the subjects iâm taking this semester, the goals for this semester and the subjects iâm actually preparing.
subjects - this is a pretty easy set up i just keep track of the things that i have to do and i mark them as completed, in progress, not startedÂ
study plan - here is a calendar where i use sub pages to write what i want to accomplish in that specific date.
the other pages are just a simple habit traker and a list of movies, books and things i want to watch/read/buy.
always sorry for the bad english - i hope everything was clear!Â
inspired by @acadhrâ
edit: i made this a template feel free to use it! -> template linkÂ
also i used this site for the calendar and the progression bar -> widgetsÂ
reading: i am the avatar, capable of mastering all of the languages
writing: alright, yeah this isnât so bad
listening: whoa there partner i sure would appreciate if you could you say that at half speed and repeat it a couple of times for me
speaking: let me practice this 3 word sentence 20 times in my head and look up each word in the dictionary and make sure i have all the right forms before i ever say it to another human being
Hi, itâs werelivingarts! Exam season is coming so soon, and some of us might deal with a lot of stress and mental fatigue while preparing for the exams.Â
Here are some tips on how to prevent and deal with mental fatigue (before it becomes too serious and leads to burnout). Exams are just ways to test your knowledge and understanding, so please do not expect too high and take care of your health! đż
i hate this so much but this knowledge is too powerful to keep from you all.
last night @phaltu discovered that setting your font to comic sans in google docs improves writing speed and creativity by an insane amount. ânoâ i said and âdieâ but then i tried it and god. i wish it wasnât this way. i wish it wasnât true. i wish i could protect you all from this but itâs real.Â
something about this font is so disarming. something about this font lets you look past the shape of the words and into their soul. iâve never written so much as i did last night, on my phone, at 2am, in comic sans.
if you have writerâs block. if you lack inspiration. if you need this. donât be afraid to use it. sometimes the things we find most horrifying are also the things we need the most. trust me. let comic sans into your life.
Youâre running away from the words youâve typed, inevitably laying more behind you. Like the old prospector running from the flame that is burning along the gunpowder falling from their pocket.Â

be sure youâre passionate about what you want to study, because youâll need a deep love to carry you through an intense program (that can range from 1 year to 7+, depending on what youâre studying) where you will sometimes have some bitter lows
related, donât go to grad school just because the job market blows and youâre not sure what to do. youâre better off taking a couple years to gain experience and skills at a job that you can then transfer to postgrad academic work later
talk to a lot of people before you decide to go somewhere. talk to professors and potential advisors, talk to administrative staff, and try to talk to current or recent students. youâll have a better idea of what itâs like, professional connections for when you start, and possibly new friends
continuing from the above point, donât go to or apply to somewhere where itâs hard to get information about the program or that people arenât responsive. if theyâre not trying to reach out when youâre a potential student, theyâre unlikely to support you once youâre there
be willing to communicate! talk to your advisor and professors if youâre having a hard time or are finding things challenging. if theyâre worth their salt, theyâll help you out and provide solid suggestions.Â
communication is key in classes as well. far more than in undergrad, participation counts. you have to speak up. a large part of grad school is to prepare you for your profession, so you need to be able to contribute to discussions.Â
