We programmers also have a Mark of the Programmer, though doctors usually just call it Carpal Tunnel Syndrome.
I have a mark too in my right hand, but not from the glass, but from a ground squirrel that bit me when I tried to catch it.
I have a small scar on my right pinkie from when I got some cleaning acid on it. The mark of the McDonald's worker :p
i have several scars from a sodium burn, does that count///
I'm amazed. I have an old scar on the first joint of my second finger of my left hand: I am left handed. I got the scar when trying to push a glass tube through a cork, when I was 12. It never happened again and I have a chemistry background.
I got a molten KNO3 burn (OW!) about 20 years ago from early experimenting, leaving a mark like a branding iron. The scar became heart shaped - probably since I love chemistry! :) Thanks for the story, I knew early on not to mess with glass near your fingers though I did plenty of work with tubing - at least THAT mistake I avoided.
does concentrated nitric acid burn count? :P
I just stuck myself with a glass pipette last night, right in the tip of my left index finger. Ah, good times. Cleaning the blood up off the lab floor was kind of annoying though.
The only thing i have is my right hand smelling different each day/week.
This is funny! I had no idea about the mark of the chemist, but as I watched this I unconsciously fingered the little scar on my left palm just beneath the thumb. When I was 12 or so I did this exact thing, and snapped the tubing off and drove it into my palm, creating the scar. I guess some things are almost universal in certain occupations.
WOOOO i didn't know The Professor was a lefty!!!
Learn something every video even if this one wasn't science related
I love the professor :) He just makes me laugh, he is so smart.
Every time I see one of your videos I wish that I could take your classes. Great teachers make learning fun and interesting.
You have to admit that we have some of the most unique occupational hazards. I have two marks: one from a shard of glass that was lodged in my thumb when the neck of a volumetric flask broke in my hands, and the other from wayward drop of sulfuric acid on my forearm, that went unnoticed for about a minute before it really hit some nerve endings.
I've got a circular mark on the first joint of the middle finger on my right hand from stabbing myself with the end of a glass pipette when I was trying to attach a pipette filler on the end.
Haha, I remember in gem chem lab, on the first day we watched a video about chemistry lab safety and one clip was do not do that and they showed a clip of a guy forcing a glass tube into his hand and making it bleed, whoever it was doing it was so bad of an actor that we all laughed because it looked so intentional instead of an accident.
Excellent and interesting as always. Please keep on telling us informative and wonderful stories ;) Love the lab as it is at the moment, all ye olde world. I was worried for a second as I don't have the 'mark' but feel happier knowing I'm not the only one ;p
Great story. Thanks for sharing.
I'm taking Chemistry in HS next year. This channel will probably help.
yup, snapped a stirring rod once in general chemistry class, nice cut on the finger
@periodicvideos That would be amazing! Either way I think I might be looking for some work by Primo Levi at my University
We had a couple of accidents during the analytical chemistry lab when we were handling volumetric flasks and we had to seal them and because of the low quality stoppers we tended to push them to seal it better. I personally had the experience of breaking the neck with this maneuver and only nicking the palm of my hand with the broken neck, but enough to start some bleeding. Another colleague wasn't so lucky because he drove the neck in her hand and had to go to hospital for treatment.
Primo Levi and Martyn Poliakoff in the same video! Respect.
@periodicvideos thank you thank you!
As an Italian it always makes me happy when my countrymen are given their dues. Especially one such as Primo Levi.
I've had the tip of a pencil stuck in my left hand for about 14 years. It's still perfectly visible.
you should have come in Palermo! It's the major capital of chemistry in Italy, plus it's where Cannizzaro made his researches!
Haven't ended up with one of these yet but I have 2 permanent scars from a test tube shattering in my hands. Which wins kids, lead or glass?
I don't think I've ever disliked a periodicvideo's video.
Maybe someone could produce a DVD series & send it to classrooms world wide as a learning tool?
-Has to go to bed- Just one more 3 minute video.. AWHH who am i kidding... (watches 1 more hour of periodic table of videos) Totally. Worth. It. :D
Periodic table tie strikes back !
I'm coming to nottingham tomorrow to do chemistry :)
Had "Every Star, Every Planet" running with a great return to theme during the description of chemists being like the Free Masons. I recommend it to friends and family alike.
hey @periodictable what is the name of the book that contains the essay? i would like to take a look at the book.
hooray for awesome chemistry stories :)
What I had in college was some yellow stains from nitric acid in my fingers, sometimes the occasional black mark from AgNO3...And of course lots of holes on my lab coat.
These were the good old days haha
A little dot of silicone oil on the glasswear will help it slip in much easier.
NO! If I only knew the professor was going to be in Italy I would have gone to Turin to meet him!!!!
It's just 2 or 3 hours of train away from my home.
I'm sad now :(... But I think it means that I have to go one day to Nottingham
Good job
These problems exists nowdays mainly by using Peleusballs (i dont know if this is the right translation to english...) which are use to pipet a liquid. My wormade told me that during his job training a person tried to stick a volumetric pipet into such a Peleusball and then the glass broke and it cuts into his arteries on his arm.
I don't know anything about chemistry but these videos are cool
Grated this was a year ago :P but you should really use your elbow as a pivot. As it has larger range of motion.
I can imagine how each science, each trade would have its own identifying scar. I have a burn scar that could only come from the soldering iron I used on the repair bench I worked at in a radio repair shop.
A friend of mine in the chem lab actually had that happen to him, but instead of trying to shove it into a cork, it was a burette pump. Had to get stitches, but easily avoidable if you hold a burette or any glass object with similar radius nearer to where you're pushing it in. If you hold it at the opposite end..well you get the Mark of the Chemist. Lol
@danx033 Same here! :D and chemistry is the only subject which i truly truly love!
space bar aswell if you use it enough, but only the left side of the keyboard
@OyVeey search for what? Periodic video? I cant find it -_-
Or ... perhaps you aren't a chemist at all....
Kidding! I love your vids this was very insightful! Keep them up! Cheers!
While working as a lab tech in college I snapped off a glass tube and drove deeply in
the palm of my hand. Luckily there no long term damage. Unfortunately it was my writing hand and the week before finals.
i remember talking about this in chem class.
ive always wondered what that is
The part he is describing rubs against the desk, which usually becomes hard and a darker shade. I have one :P
I have a nice scar on my left hand where I quirted some bromine, does that count?
@JaksProductions Same here! (my entire family actually)
I cannot wait to get my mark.
I have a mark on my hand but mine is were something went wrong and i lost the top of my finger, the same finger your on about. My finger is OK now as they replaced it with the top of the other finger then skin grafted that one from my hip....
I have a mark on the underside of my right wrist, sorta like a rugburn, you can guess what it's from ;)
He reminds me of my dear grandfather.
cool! I'm relief ! I thought this video will tell me if my persuit to be a chemist was on of a fool trying to understand what is not for his undertanding! maybe the mark of a chemist is a remainder that to be a chemist one most endure the pain of failure!
i cant wait to go to seatlle to study chemistry
cork borer = drill bit?
Will you ever come to the Netherlands? There were some good chemists and quantum physisists.
@periodicvideos facebook page?? give me link, link!
Professor: With respect I must say you tremor worse than myself after a weekend of binging on the sauce, we will never be surgeons thats for sure.
I think you make a cool Professor sir , with that hair and all , you fit the image of someone who would be called a professor . Thanks for posting
@dtrainxc Thank you very much for the answer.
@Ayerea lubrication could react with your experiment.
That's too funny. I have that. From the chemistry set I got when I was in the 5th grade.
The mark of the microbiologist is from breaking an erlenmeyer-flask while trying to put it into a shaker and cutting your hand. All of our PhDs got one and also most PhD-students, including myself.
interesting story, plus didnt know the professor was left, so am I !!!
@TheRealGeriBoss normally when setting up experiments you would use clean glass. and wear protection when handling dangerous chemicals.
The closest thing to a scar I have is the emotionally scarring after inhaling concentrated ammonia, that is an experience I never want to witness again
@renamorcen actually I'm a physicist (or trying to become one at least) :D I did study chemistry before that.though :)
can't stop noticing the tie
Put a bit of glycerin in the cork hole and use a towel to grip the cork and the tubing. There were elaborate instructions how to avoid such a 'mark' on your hand.
I've got the mark! never heard about this before
@odysseus9672 That certainly is true, but there are more professions where it's standard practice too, like biology and medicine, especially microbiology.
BTW, on the topic of washing hands, most people use too much soap, and thereby make themselves more susceptible to infection of the hands because they degrade the skin. I worked as a lab assistant in a microbiology lab, and our lab chief gave us a lecture on proper washing of hands, and why alcohol isn't always best for cleaning hands.
I read Levi's "Survival at Auschwitz" - an amazing narrative.
It will always be a high 6 through 10 to me, lefty!
oh my goodness so am i!!! left handed high five!
I've got a mark except mine is the result of an accident with a capillary tube for melting point analysis and it's located on the outside of my forearm.
i remember having to do that in high school chemistry and watching some ridiculous video about it and lab safety
Thank God for quickfit glassware :)
After seeing the phosphorus video and seeing the title of this video I was expecting some kind of small chemical burns hah
Holy crap that's like exactly what I do every time I sit down at a computer o_o
@Renmusxd entire family? For real? wow never heard of a left-handed family before! cool ;)
The professor's left handed? I am too. Haha.
Oh, wait, there it is, on my RIGHT hand yet I am right-handed.
Hahaha, an accident like that happened to me, and I had such a mark through my left middle finger, but now it's gone.
My chemistry related mark would be all the holes left in my shirts due to acid residue left on lab benches.
Yes I agree and what you say makes sense buddy! Still I get alot of callus's on my fingers and mine always go white. Either way it's nice to see us gamers like to keep our brains in check and watch videos about science. :3 This Professor here should get an Aperture science badge to acknowledge our existence. No I am just joking (Would be cool though).
Hahhah funny to see this now 😄 about 9 years ago, i poked glass tubing on my left hand, that was my first accident in lab 😄
Where the mouse mat edges rub.
Ouch, that's one painful initiation. You'd think these guys would have created a small apparatus to do the pushing along the line of insertion so they wouldn't even have to touch the glass or the cork to do it.
Yay! The Professor is left handed, just like me!
Hey ! That means that I'm A Chemist ! (Actually my scar is from when the beer bottle was crushed by my grip, Flippin' lid wouldn't come off)
that chemisty room is better than my school's ;_; but the glass wear isnt sharp at all :)
I like the mark of the electronics worker, anyone who works with an integrated circuit will have had or will get the mark: two parallel rows of small puncture wounds, caused by the person not seeing a chip that was dead bug (pins up) and resting an arm or something on it.
A friend of mine got it by sitting on a 20 pin dead bug. Quite painful, but quite funny as well.
Hehe, perhaps it's dangerous in a chemist's eye-- When I clicked on a video I was assuming the sucked-down, hollowed out flesh of the hands that happens when fat leaches through the skin thanks to strong solvents making direct contact with the skin. I've been elbow-deep (without ppe) in acetone for extended periods, and have worn, weathered hands to prove it :) So wrinkled, leathery-looking , fat-leached hands would be another good sign of a (admittedly careless) chemist!
Darn, worst ive ever done in chemistry is spill AgNo3 on my hand and stain it for a couple of weeks....i'll have to keep trying i guess
@FmMan33 LOL, No I mixed some Red P with Chlorate and boom, Bye Bye Finger.. I won't be doing that again....
