Long Hair in the Lab

A few weeks ago, I arrived in lab planning to do some chemical processing, but realized I'd forgotten a key part of my safety equipment. I already needed to go by the chemistry stock room for some other supplies, but while one could find all manner of gloves, goggles, masks, and labcoats, my missing piece of safety equipment wasn't there.

I was able to find what I needed at the campus general store for a mere two dollars: a pack of hair ties.

Why aren't hair ties included with safety gear like gloves and goggles? For those of us with long hair, that little band of elastic is crucial for lab safety. While I'm certainly aware that there are men with long hair and women with short hair, I can't help but think that the pattern I've noticed of the failure of lab equipment to accommodate long hair is related to the low number of women in STEM.

And it is definitely a pattern.

My old lab required everyone to wear laser safety glasses whenever a high-powered laser was on (known as the lab going "eye-unsafe"). I was one of three female students in lab, and we would race for the one pair of laser glasses with a plastic clasp in the back. All the other glasses has a metal clasp that would tangle in long hair. The lab was initially all men, none of whom had long hair, and I don't think it ever occurred to whoever purchased the glasses that metal clasps would be a problem.

I sometimes work in a cleanroom. I have yet to figure out how to get my hair inside the so-called bunny suit comfortably. The hood has to tuck into the suit itself, and I always have a weird lump wherever I try putting my bun. I can't just leave my hair down because I have to have a hairnet on under the hood. Whoever designed these cleanroom suits clearly did not account for users with long hair.

I wrote before that "[w]here sexism in STEM was once a stab in the back, it’s now more like death by a thousand papercuts. It’s these countless tiny messages that seem like nothing to worry about when taken individually, but add up to clearly tell women that we don’t belong."

When lab equipment doesn't accommodate long hair, that's yet another papercut telling women that we don't belong in the lab.

#MadPicLab Day 4: Patina

My husband bought me this necklace on our honeymoon. It's my most worn piece of jewelry other than my wedding/engagement rings. It's much less shiny than it used to be, but I actually think the patina gives it a cool look.

#MadPicLab Day 3: Paint

This is a picture of titanium dioxide nanoparticles suspended in alcohol on a glass slide. The alcohol evaporates quickly, so it's pretty effective paint. Titanium dioxide particles are actually a fairly common ingredient in white paint as well as toothpaste, sunscreen, and a number of other common household products.

#MadPicLab Day 2: Element

The first of all the elements: hydrogen!


Yes, you do use algebra.



I like today's xkcd for sticking up for math, but it does bring up one of my pet peeves: people who claim that most adults don't ever use algebra.

If you are reading this post right now, you almost certainly use algebra regularly. It may not look like the "solve for 'x'" problems you saw in high school, but you use it.

Have you ever split bills with roommates? "Amanda paid the cable/Internet bill, Sara paid the power bill, and I paid the phone bill. How do we split up rent to get back to even?" Yeah, that's totally algebra.

How about splitting up a restaurant bill? "I split the artichoke dip with four other people and a bottle of wine with two other people, I had the pasta dish for an entree, and I split a dessert with one other person. My share with tax and tip comes to..."

Have you ever compared prices at a store? "The package with 6 rolls of paper towels is $3, but the package with 10 rolls is $4, so that one is a better price per roll."

This is all algebra. It's a crucial part of mathematical literacy, and it's simply not true that most people won't use it. And if you know anyone currently taking algebra, help them realize how important it is to learn!

#MadPicLab Day 1: Spectrum

Well, here's a way to get me to post more!  Mad Art Lab has a very cool group project for the month of May. Every day, you share a photo based on a set theme (#MadPicLab). Today is "Spectrum."

Here is how the world looks through a prism:

It had to be done.

Guess what day today is?

(Definitely not safe for work.)
