What's the LD50 for dark chocolate covered espresso beans? I might be in trouble...

"I'm a pre-med with a 4.0, so you should change my grade to an A for your course." is my least favorite email to respond to after final grades are submitted. Some are more subtle than that, but the intent is always the same. #EndOfSemesterBlues

One of my favorite parts of every semester.

From my GOB chem textbook: "…butyric acid (CH3CH2CH2COOH), is one of the most foul-smelling substances imaginable." No sulfur, no nitrogen… I can imagine MUCH more foul-smelling substances…

It seems so strange that 1-2-3-4-5-(6) is just as likely as any other set of numbers for the Powerball lottery. #Lottery #Probability

I just tried using a pen from my desk. It didn't work. So I… threw it away instead of putting it back on my desk to try using it 30 more times. Weird.

Hey @MSExcel - Can the evaluative criterion for "=averageif()" be a cell reference? I tried using "=AVERAGEIF(BD3:BD96,"<BE98",BA3:BA96)" and got a "#DIV/0!" error. If I change "<BE98" to "<2" the formula works correctly. Thanks!

So with the rebranding, are we all supposed to refer to it as "my X" and never talk to it again? Or at least feel really awkward whenever we're together? #Sad #NotFunAnymore

I didn't really appreciate @EddieVedder's voice when I was younger. Now, it is absolute magic to my ears.

The first assignment in my Gen Chem lab is an equipment activity where students research the origin of various equipment. Half of my class says that the scoopula was invented by the @jillianldempsey group at UNC. Close, but not quite…

Grammar question: Let's say there's someone you don't know, we'll call him Doug. When his name comes up in conversation, you say "Doug who?" Or do you say "Doug, who?" It doesn't feel like there should be a comma there… #GrammarNerdsUnite

All communication about your summer class comes via your official university email. The only way I have to tell you that is... via your official university email. That's, um, challenging...

So I says to myself, "Self," cuz that's what I call myself, "Self," I says, "how do I get the current date to display in a cell in @MSExcel?" The formula is "=TODAY()", and that's simply beautiful.

We're having a misbehaving #240FS #FlameAA instrument serviced today. I am irrationally worried that it will work perfectly when the tech arrives. @AgilentChem

People in one of the art-related groups I follow keep talking about using "tempura paint". Now I'm hungry for sushi…

When you have someone (especially an older person) standing in a hot, crowded room, and they ALMOST faint, show enough common sense and compassion to walk them off the stage and sit them down before they actually collapse. On stage. During a live national broadcast.

Is that… Tuvix??? #STVoyager @TheTimRuss #EthanPhillips

I long for the highway… https://t.co/loNMXq5jak

I'm pretty sure I recognize a few of those…

Just learned the =SUMPRODUCT formula in @MSExcel. The formula returns the sum of the product of paired data. It's so cool it feels like cheating! #NewFormula #GigglingWithDelight #MyVersionOfFun
