It feels almost like a marriage...

First you spend all this time trying to get to know this person (oh, I mean you read all his papers, or at least the short ones), you talk to them, get to know them more personally, go home and meet their family (yes, I know group meetings are nothing like home, but ... focus here ok?) and then you decide if you want to get hitched. Keeping in mind that you are going to be together for eternity (ok, so only five, six, seven years... but who is counting), for better or for worse, or for worse and worse...

It is important to know how well he is going to treat you. And of course how much money he has. Yes, his money is important. I mean how else you can buy all the big toys you need to play with and food (you know ingredients for reactions). Sure, you go telling me that love (the project, his reputation, etc) is all that counts. Wait till you have to go out and earn your keep two years down the line. The man I "married” made me go out into the wild two years in a row (note the connection between my students and the wild) Have I mentioned how much I love grants running out ?(Hey, Selly, don't be bitter. TAing is not so bad...)

But I deviate. Good luck choosing your advisor (for those who were too involved or confused in my convoluted analogy to realize).

On the issue of theories of mine...

I am told that chemical reactions are like having and raising a baby. First there is all the fun and activities to start out. Then there is this really loonnngggg wait till the baby gets here or the reaction goes to completion whichever you can relate better to here. In that time you pretty much do nothing but sit around and twiddle your thumbs. Of course I am sure my dear advisors would much rather prefer that I sit behind my desk and studiously catch up on my reading on my project and literature and such from scholarly journals (but what is the fun in that). Instead I am updating my blog. Naughty, naughty me.

All of today has been me sitting around waiting for my DSC to go. It is too bad I am about a 20minute walk from my own lab. It would have been great if I could go back and forth, that way I could also get something else done. But there is really no point since in the time it takes to get to my lab, I will have to put in a new sample or do something of the sort.

Ok, back to theories. So finally the baby arrives. Usually in the first few days (hours) they require a lot of work and attention (think working up reaction, purification, columns, crystallization). As they grow, you need to be careful with them. Too much attention and they get spoilt, too little and they go really bad (ask me about my little explosion, my hood is still greasy from the oil spill).

Ok, so my point is that I am bored to death in lab. My eyes are beginning to glaze over from reading these articles. HELP!!!

Explosion!

Random blog filler aka old journal entry

Today, I am going to be talking to you about explosions. I will start by introducing the general concepts of explosion, comment briefly on why they happen and focus the rest of my talk on why they shouldn't happen (at least not to me)...

Think loud boooommmmm. Think of everyone close by gasping. Think of that weird feeling you get when you know that that noise must be coming from your hood and no one else's. After all, who else in that module has anything explosive?

Or another scenario: You have the beaker tipped over the flask, and you are just pouring, and then you think OH NO! But in this case, you hand is swifter than your mind. Note that this is not normally the case.

Yet another scenario: Of course not! That never really happens. I mean, who are they kidding? Or at the very least, how big of a fire can a little drop (or piece, or crystal...) cause? You know the writers of general chem. books like to exaggerate.

OK, now let me speak from experience. First: if you think that booom is from your hood, you are probably wrong. It is really from mine. Second: Pirahna and acetone (anything organic actually) is a really bad idea. And finally, Butyl lithium (and BBr3, and a whole host of others), will really catch fire when exposed to air (think spill) and a paper towel is not what you want to wipe that spill with, no matter how close they lie and how tempting they look!

So how do explosions happen? Let me list a few: 1. Reactions in closed tubes. My problem here is that it worked great the first time. So why not the second time? All the grease I am still having to clean up, after so many months tell me that I obviously did something wrong. Moral of story: If the reaction can be run in an open system, go for that.

2. Some things just don't like each other. Just like some girls just don't like guys or vice versa (but I deviate here). Spontaneous reactions really do exist. Every so often, ΔH and ΔS are just right and even the temperature too. Did I mention that explosions are exothermic reactions? Ok, so it is obvious...

3. Curiosity can literally kill the cat. I mean it. Really, if all the text books say it is a bad thing, it probably is...

Random quote 2

Is caesium poisonous? I think I spilt some in my mouth.

Another frustrated colleague.

How you accidentally spill a chemical in your mouth, I do not know. Good thing it wasn't really ceasium, and he didn't really spill. I love the guys I work with. Most days.

Spectra (and data) are so over rated. What ever happened to blind faith?
---------------------------------------------------------------- Frustrated colleague.


I know exactly how he felt. In a sense though, it does take a lot of faith to trust all the different data sources and analytical tools that we use daily. The irony is that few scientists will admit to having faith.
