Day 339: What will school look like?

School

Here in the US we paused, it was only for a moment, it wasn’t long enough, and not everyone did it, but we paused. Then just as quickly as we tried to adapt to the changing times we went back to pretending everything was normal. Beaches opened, restaurants opened, bars opened, we saw celebrations and parties and we ignored a single digit daily death count, which turned into a double digit, then triple digit, now we’re hovering in at roughly 1000 deaths a day from the pandemic.

Day 321:Wear the damn mask

Daily Life In Belgium Amid Coronavirus Outbreak

Today is just a simple plea to my readers. Wear the damn mask. It’s not that hard. When you go out you put on your clothes, you can put on a mask too. Since people seem to be making this a political statement now, I guess I can explain why it’s not one.

Day 312: Yes, the protests are still going…

George floyd

It still appears there is a media blackout on the protests (first mentioned in my other post). That doesn’t mean we’ve stopped though! It also unfortunately doesn’t mean the police have stopped. In fact we’re seeing some really… umm scary tactics being used by the police to * checks notes * beat us until we stop protesting police violence.

Day 311: When voting isn’t enough

Gerrymander

Rawr! Beware, the Gerry-mander!

I’ve been debating about writing this post and it’s just been rattling around in my head for the past month or so. Voting can change the course of history, frankly we saw that in the 2016 elections, but we also saw something else. Your vote doesn’t matter and that isn’t by accident. But wait, I just said voting can change the course of history, so how does it not matter? Well for that we need to go back, way back.

Day 309: No tests, no worries

head in sand

If I ignore my bills, I would have very few, if any. If that logic seems, well wrong, then I’m not surprised. Ignoring something doesn’t make it magically go away. Yet, Trump has touted, yet again, that if we slowed or stopped testing, we would have very few, if any cases of COVID19. I mean, with that kind of logic, you could have no more bills with this one weird trick!

Day 307: COVID19 and BLM or why you should wear a mask

statue

Despite the media blackout the Black lives matter protests are still going strong. To say I’m proud would be an understatement. Unfortunately with all the protests going on people are claiming that COVID19 isn’t as bad as people said it was, or that the protesters should stop because of the pandemic. The critiques all miss the point, this one simple trick will slow the transmission and it really works.

Day 304: It’s still just the first wave

COVID-19

♫ One of these things is not like the other… ♫

COVID-19 is making headlines again and news reports are claiming the second wave is here. Well, that’s not quite right, we never actually stopped the first. We literally cannot have a second wave of outbreaks if the first wave is still going strong, it’s just a continuation.

Day 281: The New Colossus

Statue of liberty

The march of time stops for no one, yet we shut down the world. Only for a moment. Then that moment passed, but not by choice. There is a pandemic going on, tomorrow we will most likely pass the somber 100,000 official deaths from COVID-19 in the US. There is a very good chance the actual number is much higher. It hasn’t stopped, it won’t stop, but somehow we are choosing to ignore it.

Day 253: A race to the finish

finish line

Well still quite a bit of work to do and some of it was frustrating, but here we are. So let’s run through what I’ve got left to do before the end of the term (ALREADY?!) and talk about the next few posts since I have somewhat of a plan… for once.

Day 252: Dead…line

dead...line

Today is the day, my group presentation is due. Is it done? Well… sort of? Okay not quite, but we’re getting there. My group member still sucks, but since I yelled at him (in a professional manner of course), he’s gotten a little better and has been more responsive, so what’s the hold up? What a great question, let me explain.

Day 251: Deadline tomorrow

deadline

Well the apocalypse can’t stop the gears of education. Tomorrow is our final presentation for the class I am in, so there is work to be done and expectation maximization will come another day. For now let’s give a quick rundown of what I’m working on.

Day 250: Maximum Likelihood Estimation

probability

If we are going to talk about expectation maximization (now that I’m done complaining for a bit), we are going to have to introduce the idea of maximum likelihood. It’s going to be very easy to introduce, but it is a very powerful tool in estimating the state of something. Of course, it takes understanding a little bit of statistics, but trust me, if I can understand it, so can you.

Day 249: A stern email later…

angry

Photo of me responding to his email …

I don’t want to jinx it, I really don’t, but I have an update on my group member situation and it isn’t completely awful! I mean, I’m still doing all the work and blah, blah, blah, but I’ve got an interesting story and I hope that things will be better now.

Day 248: A Virtual Conference

background

Every zoom meeting I try to break my PI and get him to laugh, this was my last attempt, still nothing… my work continues.

This will be my first conference since the pandemic and it will be a virtual one. To be completely honest, it wasn’t until yesterday that I was reminded we had one today. It’s a little bit different from our normal routine and I think that is what is throwing me off.

Day 247: The Kalman filter – Part 2

Kalman filter estimate

The Kalman filter converges on the optimal state estimate using noisy measurements and a model that we create.

Okay I lied, I think we can do a better job explaining the Kalman filter, more importantly I have a fun little demo I can share with everyone. It’s not mine, but I like it a lot and it will give you a feel for what the kalman filter does. So let’s get started!

Day 246: The Kalman filter

We have 3-dimensions here even though it is a 2 dimensional problem. the third dimension is time, this way we can see the path over the course of the recorded time. Notice there are no units, becuase in this case we were working with synthetic data so the units were meaningless and I did not include them.

This is just one application for the Kalman filter, I estimated a two dimensional position using a random walk model.

Notice there are no units, becuase in this case we were working with synthetic data so the units were meaningless and I did not include them.

Since we’ve been talking a lot about it, I thought it might be a good idea to formally introduce the Kalman filter. This will be a semi-high level introduction (like my knowing your spinal cord series), but at the end of it you should have a relatively good feel for what a Kalman filter is.

Day 245: Fine, I’ll do it myself.

Thanos - I'll do it myself

I will not fail this class becuase of a shitty team member. I will not allow it, I’ve put too much effort and time into this class to do poorly at the last minute because my team member can’t be bothered to do the job he agreed to do. I suppose, this was… inevitable

Day 244: The end of the term!?

end of term

Okay, where the hell did that come from?! It’s almost the end of the school term. WHAT THE HELL!? It feels like we just got started, but my instructor just sent out the final assignment, which is due the last week of school… next week. I’m sort of freaking out right now.

Day 243: Deadlines approaching!

deadlines

It seems like it’s been non-stop for me left and right. I have experiments to do, papers to write, and classes to work on. With the pandemic I was hoping to get a chance to take a break, but nope it seems like I’m even busier than normal. I HAD thought that I was caught up finally when I finished processing some of the experimental data I had laying around, but nope I was reminded yesterday that I had not one, but two major deadlines coming.

Day 242: Experimenting in the time of a pandemic

Experiment-blur

Another day forward in our new normal. I’ve left the house exactly once in the last two weeks and while it’s nice not having to commute to school, I do miss living in a world without the constant fear of catching the virus. What day is it? Who knows, it doesn’t matter anymore. I do have some things coming up though, so let’s talk about experimenting in the age of COVID-19.

Day 241: Modeling the COVID-19 Pandemic

COVID-19

COVID-19

Today is the day. I submitted my super high level explainer video on how I modeled the COVID-19 about  a week ago and I got an email from my professor telling me that it was great (yay) and that she had uploaded it to her labs youtube channel. That means I finally get to share it with all of you!

Day 240: Conferencing at a distance!

video conferencing
video conferencing

Not everyone has access to such luxurious setups.

It’s that time of the year again, well one of two times of the year really (for us anyway). Unfortunately with the coronavirus conferences are better held virtually than in person. While I have mixed feelings about the usefulness of meeting virtually to share our work, I am grateful that there are workarounds, don’t get me wrong, but there are some logistics that make it, well painful and some things that make this worthwhile.

Day 238: Well spoke too soon…

USS Roosevelt Outbreak Navy Guam

USS Roosevelt Outbreak Navy Guam

Yesterday I gave an update on the USS Roosevelt situation. It was basically an update to the predictions I made about how the military was going to handle it and it turns out I was on point. Today is going to be a short post, but I guess there is more to add to the story so let’s just go ahead and get started.

Day 237: Coronavirus and the military response – Part 3

USS Theodore Roosevelt

USS Theodore Roosevelt

Well it’s been ten days since I made my predictions about what would happen with the crew of the USS Theodore Roosevelt and it looks like we have some updates so let’s see how close I was to guessing what was going to happen. Let me just start by saying, I hate it when I’m right about this stuff. Some of the things I predicted were longer term, but some of the shorter things we can compare.
