Feels Like Friday

Friday is not just the name of a day of the week, it is the name of a feeling. And sometimes, the whole universe feels this feeling with you (as evidenced by nothing going right and equipment often not working on a very particular day of the week).

This week, every day had been feeling like a Friday for some strange reason, and then I realized that this week really was the “Friday” of the year.

No wonder I have been running high on introspection – typical “Friday” mood. Not to mention, this “Friday” also marks the official mid-point of my PhD, which means that the time is ideally situated to look back on how far I have come and how to best manage the rest half.

So, upon the (partially) successful survival of my two years in Finland and in my PhD, I sat down to count my little successes along the way, which took me perhaps five minutes, not much there. I’m also pretty sure that I’m still navigating the unpredictable waters of culture shock and adjustment, but now I find myself on stable ground more often than not (I would probably put together my final thoughts on the subject, which are still worth about three to four blog posts). 

But there is light in the middle of this tunnel. Lately, I have finally been seeing some shape and form from my last two years of optimizations. Or that’s what I would like to believe (the human brain is really good at erasing information that causes it discomfort, so maybe I’m living in my little, custom-made, fantasy bubble).

Today, I did a little exercise. I made boxes for each week I was getting in the next two years (inspired in part by a part of this brilliant and funny TED Talk). Before this, I didn’t know how uncomfortable a task as simple as drawing and counting boxes, can be.

As of 29 December 2019, I have 105 boxes. Don’t look like all that much.

Really put things in perspective for me.

Bat Signal

A couple months ago, while measuring some samples with an oscilloscope, I witnessed a never-seen-before phenomenon.

As is completely obvious, the results were undoubtedly a part of some bigger picture.

Is this a signal from the universe? Some kind of a message?

Is that you, Batman?

How To Science

So today, I came across this very inspirational post and decided to hold onto it. It was a good reminder that discovering you are wrong is still science (if attempted scientifically).

The Glove Box

Lately, I’ve been interfacing with the glove box a lot, which is next to inevitable in my field of study.

If you have never seen or heard of a glove box before, I have got an exclusive, self-explanatory diagram of it to show. But like all things science, this story is not as simple as that.

… But suffer, one must: The bare-minimum illustration of a glove box. (If text too small, click on image).

If your glove box is big, in a looming sort of way, it can be quite intimidating at first. And it can seem so… fancy to be working in a glove box then. Like you had to qualify for it. Well, with more experience, you find out that the basic qualifications you need are: 1) having a piece of work that you need to do in a glove box; and 2) appropriate height (as in, tallness of a scientist) relative to the glove box (but let’s be real here, the second criterion doesn’t really exist – stand on a chair if you must).

Plus, having to wear thick big gloves of the “glove” box, it becomes plain clumsy to work in it. And my excuse of “I-am-still-new-to-working-in-the-glove-box” expired a long time ago (which I actually whined about for quite some time compared to normal, not-so-fussy people).

So now I have had to accept that I AM fully responsible for whatever clumsiness I commit – which makes me not-such-a-big-fan of the bumbling person who works in the glove box and cannot even pick up a bottle without first dropping it a couple of times.

The “person” who works in the glove box? Pfft! That’s not me! She is Qudsia Forcephands (secret note: that’s the name for my alter ego for when I have to work in the glove box). She had to be really pushed to start working in there and she kept complaining about how she was still new to working in the glove box even when it was her sixth time! (it’s UNBELIEVABLE what some people will say so they will not have to work, it’s really sad).

But I think, with time (and with MUCH encouragement and suggestions from me), Forcephands is learning the tricks of the trade and she has become waaay better at navigating inside the glove box now. And, as the name might give you an idea, she is now quite adept at using forceps almost as if they were extensions of her hands (or gloves of the glove box).

Forcephands is still somewhat lazy and I often have to give her pep-talks, and even now, she keeps dropping everything in the glove box (are all those forceps inside the glove box there for nothing? Tut tut). But what can you do, some people will just remain at their level no matter how much you try. She has, though, become quite independent at working in the glove box now and, I have to admit, I am somewhat proud of her.

(But I still don’t completely trust her).

#3: This Week in Science: Eclipsed

So this particular week in solar cells (some weeks ago), I finally managed to make my own batch of solar cells – after which I started to consider myself qualified enough – in the capacity of an independent solar cell researcher ^_^

Mistakes That Follow You Around

Sometimes, things go wrong in your life that, no matter how much you try, you just cannot hide them.

Especially if you work with smelly chemicals in your lab.

You spill one of those and your biggest wish would be to bury the evidence of your clumsiness. It’s all well. You clean up, no big damages. No one saw you. It should be fine. Only if it was this simple.

The smell of the chemical will not let it be so. It haunts you and follows you around everywhere you go.

And people start asking questions. Questions that should not have been raised in the first place, that are best left unanswered.

And then, you have to admit that yes, it is you. This is something that you have done. And it is definitely you who smells like that chemical.

But in this adversity lies a masked opportunity. An opportunity to develop your own line of perfumes that smell like chemicals in your lab. Then you can wear them all the time and get the people in your lab accustomed to those smells.

So that next time, they won’t even know (plus you generate revenue. Win-win.)

Square Tomatoes

Some days ago, I found out about the square tomato.

In short, the “cultivar VF-145” was developed at UC Davis to get to a more sturdy kind of tomato that wouldn’t squish so easily and wouldn’t roll of conveyor belts. It is not really square, but just “less round” than a more round tomato.

Anyway, many different ways to look at, and solve, a single problem (and all the subsequent problems that arise because of that). Less manpower – Get in a machine to do it. The tomatoes roll off and get crushed by machines – Change the tomatoes.

Or perhaps it depends on the person you bring the problem to. Changing the tomato would probably be the first thing that comes to the mind of a plant breeder – but not necessarily to the mind of a solar cell researcher (not that solar cell researchers are the best people to solve tomato problems… It’s probably a good idea to leave them to tomato experts). But it does make one wonder: would the solution be still the same had someone else been on this task? Someone with a slightly different background and technical expertise?

I have had times in research when I was stumped by a mundane, and most of the times non-scientific, problem (which is, of course, mundane only in retrospect – no problem is too stupid, too mundane, or too small when it is in the phase of being a problem). I only had to move around, sometimes up and down some stairs, throwing the question at people I knew – and one of them would reply with an obvious solution that would leave you in a speechless why-didn’t-I-think-of-this state.

Times like these are when you find out who your real friends are – They are the ones who will not hesitate to break you out of your tunnel vision and bring you play-doh to seal your glassware airtight when you need it.

However, my biggest concern is completely unrelated to this now: Have I been eating square tomatoes all my life, thinking they were round when there were probably rounder tomatoes out there? Have I even seen a truly round tomato ever?

Machine Learning

I would like to, first, apologize for the misleading title.

Wikipedia defines “machine learning” as:

Machine learning is a field of computer science that uses statistical techniques to give computer systems the ability to learn (e.g., progressively improve performance on a specific task) with data, without being explicitly programmed.

But that is not what this post is about.

You see, as a junior scientist about to embark on your career path, one thing you should do is learn to use different machines. Some machines will make something for you, whereas others will tell you that those machines are probably not working, and despite all your efforts, it will be some time before you start getting good samples or results out of any thing in your lab.

So if you work in a lab, you’ll now have a very good idea of who rules there: It’s them. Now and forward, in your time as a researcher, you’ll go into many labs, meet a lot of people, and learn a lot of new stuff… but nothing and no one will judge you like those silent machines sitting smugly atop work benches of your lab.

Many a times, I have started working with one, thinking, oh this is going to be one of the easier ones. Never has that attitude worked for me. It’s like you cannot trust any single one of them; even the ones that you think you know, won’t think twice when it is as tempting as shattering your trust in them.

They don’t care if you are enthusiastic about research and have chosen this field as your career with such joy. They will happily make you think that you have nice typical graphs* in your presentation that you are about to show in your group meeting. They want you to suffer, to taste embarrassment, like they want to see how long you are going to last in this field that you have been so passionate about …

… Until you have proven yourself worthy of research.

As a result, one of the few things I have always found myself doing in the beginning is to start gaining favor of the machines that are in my lab. To build good rapport with them. And it is not easy, not with every machine. Even after you feel you two are going along well, they will still  test you, or just throw you under the bus when they feel like it**.

If it all sounds depressing to you, let me tell you there is hope. Somehow, after you have stood beside them long hours and worked with them at odd times***, they will start to slowly accept you and let you enter the ranks of researchers. It’s blood, sweat and tears to gain that kind of trust, but you can gain the status of meh-you’ll-do in the eyes of the machines.

But don’t ever expect them to start liking you, because that’s ridiculous, they probably don’t have a heart.

 

 * Well, okay, they may have been looking a little weird to you as well, but early on, you wouldn’t know that, thinking this is probably how they are supposed to be.

** Which tends to happen most on Fridays, followed next in probability by Mondays.

*** Condition of high-levels-of-consistency needs to be met with these requirements of long-hours and odd-times.

Breakdowns

Recently, the hotplate I had been using was glitching a lot (it was fine when I was not using it this much). And then I saw this in my social media newsfeed and this seemed to hit right on point:

Currently, I think we have both started to understand each other more, so we have been getting along better. Now, I have nothing but honest praise for the hot plate.

Dear hotplate, you are the best! 🙂

(I took the image from this link but could not find whose brilliant theory this actually is).
