Lots of lovely science on Tumblr! (Thanks for the mention brainsx)

dimethylsulfoxide:

Acetaldehyde C2H4O

  • Appearance: Colorless liquid
  • Molar Mass: 44.05 g/mol
  • Density: 0.784 g/cm(at 20°C)
  • Melting Point: -123.37°C
  • Boiling Point: 20.2°C 
  • pKa: 13.57

Acetaldehyde is one of the most important aldehydes, occuring in coffee and bread. It’s more well known as being the metabolite of ethanol by alcohol dehydrogenase, thought to be the main cause of hangovers. It undergoes keto-enol tautomerism, but only a small fraction of acetaldehyde is in the enol tautomer. Acetaldehyde used to be a precursor to acetic acid, however now it’s more important as a precursor to pyridine derivatives like pentaerthritol. It’s toxic when applied for extended periods, is an irritant on the skin, eyes, and mucous membranes, and is a possible carcinogen. It’s found smoke from cannabis and tobacco.

Done.

Today, I finish this year’s examinations with an overall optimistic feeling at a first approximation. I find this somewhat difficult to type because I don’t want to think about the exams anymore, and also because my wrist is tired from five half-hour essays.

Now that exams are over, it’s time to return to other things like maintaining this blog. It seems to me that my “personal” blog (that is, this one) has become swamped with science sheets from over the past year - this year I made 80 of these. Some organisation is in order, here, I think.

Secondly, although all examinations are done for the year, not all tests are. In a few days’ time, I have my first crack at the driving test. So here goes. :)

I’ll probably spend my last bit of time in Cambridge beginning to revive some of the old stuff I’ve dabbled in - this blog, the Chlorophynagogue, the novel, and so on. That’ll carry on properly once I’m home.

Keeping a plastic mind receptive to new learning is a year-round thing. Just because there’s no learning to do doesn’t mean there’s no learning to be done. Duolingo has been my bringer of such “mental plasticity” where I get tired of thermodynamics, cell assays, or revision, and will continue to over summer. Yeah - when you get tired of learning, why not take break and learn more? Somehow that makes sense.

All this year, I’ve violated my own pledge to devote at least a little bit of ‘me’ time. Actually, across a whole year, about half of that year belongs to me. It’s all in a single block called the long vacation.

A long vacation. Something to look forward to, but it’s so easy to get bored with so much time! Those projects above, and perhaps some other I’ll dare to try, will occupy me once I get back home.

But for now, while I’m still in Cambridge, I’ll prepare for the next thing, and take it easy all the while.

And a visit to Forbidden Planet and some sushi is in order.
