It's a dry, windy day. I had my left hand stationary on my cat's back and was petting him with my right hand. I noticed when I removed my right hand from contact with his fur, I got tiny shocks in the middle finger of my left hand, but only when removing my right hand and only in my left middle finger. (He didn't seem to notice any shocks.)

Why is this very specific type of electric shock occurring?

it's here.

I started Dear White People with a skepticism towards their intent. I thought the name of the show was an indication that it would be another example of media exploiting identity politics. I began watching with that expectation and held that perspective for quite a while afterwards.

The characters and story itself immediately engaged me. I was compelled by virtually every person and their experiences. The students of Armstrong-Parker are unique, passionate, ambitious and intelligent. As a natural result of this perspective it was easy for me to want to entertain their ideas and arguments.

This experience was at odds with another: The students extended very little thought and charity towards any opposing ideas or experiences of people outside of their ideology and social group. I felt uneasy that these characters who I liked and respected were making so many failures in upholding their intellectual integrity.

After a long period of confused enjoyment I realized that my issue was a false assumption. My initial expectation felt like it was being reinforce continuously so I never thought to reconsider the shows intent. After some reflection I think the actual intent is demonstrating the deeper problems of identity politics through the “good” characters exhibiting real human flaws. The racial issues are, of course, important and I’m glad to have engaged them but the true value is in the subtleties of how people interact with each other on these issues.

Prometheus (2012), Alien: Covenant (2017), Life (2017), The Cloverfield Paradox (2018), you name it. Why is everyone in the team is a complete incompetent buffoon? Why is the science behind the films so bad? Why do the protagonists do stupid crap? The crew from Alien IV looks like geniuses compared to these people.

Am I the only one who is seriously disturbed by this trend?

I admittedly didn't reread the docs, but a search for "self" showed no results.

EDIT
a search for "self-promotion", and not "self promotion", pointed me to this previous thread:

For those that don't know, NaNoWriMo (National Novel Writing Month) is an annual challenge to write a 50,000 word novel over the course of the month of November. That translates to roughly 1,600 words a day. More info on NaNoWriMo here.

I first tried it two years ago though I fizzled out at around 10,000 words and moved on to another WIP. Last year I didn't formally participate though I made an effort to write something every day. Not sure about my word count.

This year I'm doing a series of short stories in a shared setting since I've been doing more short form writing as of late and I've been mulling over the idea for a few weeks now. It's a nice way to experiment with different settings and themes within a "singular" work. I've made some notes on plot hooks, settings, characters, and ideas I wanted to explore, so it's only a matter of writing the stories now. Maybe I'll even share excerpts as I go along.

So has anyone else made plans to do it this year?

feels like we should probably have one of these in here since it doesn't appear we've had one of these as a community in ~creative in awhile--if ever.

i've spent the better portion of my day today working on a census form for the kryfona kingdom, which is one of the many countries in my fairly large worldbuilding effort. the first page actually came out really well, i think, so that was time well spent. i've considered making a post about some of its more intricate detail since i think some people on here might enjoy that, but for now i've opted to just make this general thread since i dunno how well it'd go as a discussion topic. maybe if y'all think it's worthy of one? idk.

anyways, what creative things have you been working on recently?

I was wondering about uncommon game mechanics recently and would like to get some inspiration for a possible next project. :)

I personally enjoy games in which a story is generated organically based on the user's gameplay.

Progressive metalcore outfit Silent Planet has finally released their third studio outing after teasing with almost half a dozen singles released. Like their previous efforts, the album is drenched pathos.

Garrett Russell's lyrics continue to impress and be the thing that truly sets Silent Planet apart from other heavy rock outfits on the scene right now. His employment of footnotes in his lyrics to help the listener know his purpose in word choice has become a hallmark of the band's output. But while Russell's lyrics have always been good, When the End Began marks a new level in his delivery. His guttural lows are booming and intense in songs like Northern Fires, while his understanding of timing and beat helps punctuate his words much better than he's ever done before, really shown off on Share the Body. Not to be content with that, he even attempts some clean vocals on the albums with a fair amount of success.

This is all complimented by guitarist Mitch Stark's djenty riffs on the guitar. While Silent Planet has been known for their emotional aesthetic, Stark sneaks in a bit of catchy riffs in tracks like Firstborn. Planet has always straddled the line between ambient and heavy, and they continue to in When the End Began, as guitars will effortlessly switch from chunky riffs to fleeting noises.

If there is a better heavy rock album coming out this year, I'd like to hear it, because I honestly want the feeling of being blown away that When the End Began gave me a second time.

We have the "Exemplary" label for comments, which identifies comments as particularly good, and even boosts their ranking within threads.

Now that we've had this for a while, I keep finding myself want to do the same for topics. I'll read an article and want to give it an extra boost because it's better than average.

I'm ready for an equivalent to the "Exemplary" label for topics.

Introduction

I want to give an introduction on several physics topics at a level understandable to laypeople (high school level physics background). Making physics accessible to laypeople is a much discussed topic at universities. It can be very hard to translate the professional terms into a language understandable by people outside the field. So I will take this opportunity to challenge myself to (hopefully) create an understandable introduction to interesting topics in modern physics. To this end, I will take liberties in explaining things, and not always go for full scientific accuracy, while hopefully still getting the core concepts across. If a more in-depth explanation is wanted, please ask in the comments and I will do my best to answer.

Today's topic

Today's topic will be quantisation, explained through the results of the Stern-Gerlach experiment which was first performed in 1922. This topic treats a much more fundamental concept of quantum physics than my previous topics.

What is the Stern-Gerlach experiment?

In 1922 physicists Stern and Gerlach set up an experiment where they shot silver atoms through a magnetic field, the results of this experiment gave conclusive support for the concept of quantisation. I will now first explain the experiment and then, using the results, explain what quantisation is. If you would rather watch a video on the experiment, wikipedia provided one here, it can be watched without sound. Note that I will dive a bit deeper into the results than this video does.

The experiment consists of two magnets, put on top of each other with a gap in the middle. The top magnet has its north pole facing the gap, the bottom magnet has its south pole facing the gap. See this illustration. Now we can shoot things through the gap. What do we expect would happen? Let's first shoot through simple bar magnets. Depending on how its poles are oriented, it will either bend downwards, upwards or not at all. If the bar magnet's north pole is facing the top magnet, it will be pushed downwards (because then north is facing north). If the bar magnet's south pole is facing the top magnet, it will instead be pushed upwards. If the bar magnet's poles are at a 90 degree angle to the two magnets it will fly straight through, without bending. Lastly, if the bar magnet's poles are at any other angle, say 45 degrees, it will still bend but less so. If we send through a lot of magnets, all with a random orientation, and measure how much they got deflected at the other side of the set-up we expect to see a line, see 4 in the illustration.

Now we'll send through atoms, Stern and Gerlach chose silver atoms because they were easy to generate back in 1922 and because they have so-called spin, which we will get back to shortly. We send these silver atoms through in the same way we sent through the bar magnets; lots of them and all of them with a random orientation. Now what will happen? As it turns out all the atoms will either end up being deflected all the way up or all the way down, with nothing in between. 50% will be bent upwards, 50% downwards. So silver atoms seem to respond as if they were bar magnets that either bend maximally up or maximally down. In the illustration this is labeled 5.

If we were to take only the silver atoms that bent upwards and sent them through the experiment again, all of them would bend upwards again. They seem to remember if they previously went up or down rather than just deciding on the spot each time if they go up or down. What model can we think of that would explain this behaviour? The silver atoms must have some property that will make them decide to bend up or down. Let's call this property spin, and say that if the silver atoms chose to bend up they have spin up, if they chose to bend down they have spin down. It seems that these are the only two values spin can have, because we see them bend either maximally up or maximally down. So we can say the spin is quantised; it has two discrete values, up or down, and nothing in between.

Conclusion

We have found a property of atoms (and indeed other particles like electrons have spin too) that is quantised. This goes against classical physics where properties are continuous. This shows one of the ways in which physics at the smallest scales is fundamentally different from the physics of everyday life.

Next time

Next time we will investigate what happens when we rotate the angle of the magnets used in the experiment. This will lead us to discover other fundamental aspects of physics and nature, quantum superpositions and the inherent randomness of nature.

EDIT: part 2 is now up here.

Feedback

As discussed in the last post, I am trying something different for this post. Talking about more fundamental quantum physics that was discovered 100 years ago rather than modern physics. Did you like it? Let me know in the comments!
