I'm enrolled in the Kalamazoo Area Mathematics and Science center, and I'm doing a research project on supercooling, crystallization, and now apparently I have to include the definition of "polymorph" as well in my glossary. 10 page minimum! lol oh yeah I'm a sophomore in high school. Great videos, they really help me not only understand chemistry, but they are rather exciting as well! I look forward to more in the future.
Im planning a trip to england and I am seriously putting nottingham on the list of places to go. I have to meet the professor and shake his hand. I love these videos so much.
@tonberrytoby the proffessor answers quite clearly that polymorphs refer to the arrangement of molecules or ions in a bigger structure (like a crystal lattice), not their internal arrangement. You could say it's one level higher organization.
This is cool! In geology polymorph are also very important like calciumcarbonate can form either calcite or aragonite. Iron sulfide can form pyrite or markasite. In some cases ground water can be considered undrinkable just becouse of which polymorph is present since one form may be more solveble in water.
Not yet sadly. I planned on going this summer and it turned out to be more expensive than I believed it to be. But I've got some money saved up and I'm just going to add to it and maybe go over the winter!
@jayjjj3 - I'm going to be taking the AP exam this fall. Honestly it isn't that hard to learn the extra material if you have a good teacher, just make sure you adjust to the elevated pace and don't fall behind in your comprehension of the material
Im studying pharmacy in northern ireland, this helped alot with my physical pharmacy module. Any chance there be more videos coming with links to pharmacy ?
@DeathIzurfriend There r, polymorphs are same compound with different crystal structure while isomers are compound with same molecular formula but different structural formula. Polymorphs must have the same chemical properties but usually have different physical properties.isomers' chemical properties and physical properties usually are different
Calcite and Argonite are common Polymorph crystals. I have a nice collection of rather large calcite crystals Diamond and Lonsdaleite are two extremely hard allotropes of carbon
@chaosrealm93 But in the moment when a compund enters the body it begins to metabolise it so when you take a certan amount of substance at one time it will be gone after a while. so the final concentrataion of a substance (in e.g. your blood) depends on the time it takes to dissolve the dose you swallow.
Polymorphism is something different than stereoisomerism (molecules with identical molecular formula and sequence of bonded atoms, but still a different 3 dimensional structure), right?
@sypher113 no, you're not ;) And you would be the correct one, since sheep is only one of the polymorphs. It's kinda silly use of the word though, but as you know it it refers to magical morphing to a differet creature, and poly- comes from many possible morphs. It has been used in many games.
is it just me or do other people notice that the professor cannot keep his hands still (as in: they shake when he's relaxing them). i've been noticing this for a while now and i'm actually a bit worried...
Interesting - this was not something that was on the curriculum 30 years ago when I studied Chemistry - though the idea is straight-forward to understand - I suspect that the interest in polymorphs was not there as they had not put enough money into studying them at that stage.
Wheres the polymorph? Oh no, its changed again hasn't it? Biding its time until people let there guard down, and then BAM, it devours their most powerful emotion. OMG IT'S THE SWEATER ON THE CHAIR!!! RUN PROF, RUNNNN!!!! ;) couldn't help myself, even if I couldn't come up with a funnier delivery, the reference demanded to be made.
brady! has the prof watched a tv show called "Breaking Bad" it's about a chemistry teacher who gets cancer and to provide for his family decides to cook up some meth.
If it wouldn't put such a hurting on the scientific community, I'd like to kidnap the professor and just keep him in my house and ask him questions all day.

I live in lincoln- only 40 minutes away from the university, and i have met the professor on when he was buying his lunch :P

I LOVE THIS GUY! so good at explaining everything!

Fascinating, as always.
Thanks, professor!

crystal is fasinating chemistry! love it, thanks. like neo magnetic ball, positive and negative charges form different structures.
@DeathIzurfriend There r, polymorphs are same compound with different crystal structure while isomers are compound with same molecular formula but different structural formula.
Polymorphs must have the same chemical properties but usually have different physical properties.isomers' chemical properties and physical properties usually are different
@periodicvideos Sounds nice! Definitely a place I would like to visit if I'm ever going to the UK.
Calcite and Argonite are common Polymorph crystals. I have a nice collection of rather large calcite crystals
Diamond and Lonsdaleite are two extremely hard allotropes of carbon
Best Campus I've ever seen, saying that it's enjoyable! being going to the university for a year or so :)
Reminds me of L and D versions of opioids. One has pharmaceutical uses, while the other causes paralysis.
Pretty much every word that starts with "poly-" reminds us of you, Prof. Poliakoff.

What is the difference between an isomer and a polymorph?

To me Polymorph is that shape shifting creature of Red Dwarf.
Great video. It makes me think I'm going to like studying Pharmacology next year :)
Excellent video as usual!!
Keep it up!

@FraApplez It confuses me when anyone dislikes any of these videos. I can't figure out what, exactly, they don't like.
Interesting - this was not something that was on the curriculum 30 years ago when I studied Chemistry - though the idea is straight-forward to understand - I suspect that the interest in polymorphs was not there as they had not put enough money into studying them at that stage.
I would have paid more interest in Chemistry at school had someone like the Professor been teaching....
@thinkppl Its just an effect that comes with age mostly, i wouldn't be too concerned about it.
This could be why generic and brand name drugs have different effectiveness in some people.
@periodicvideos
Would it be possible for you to film a tour of University of Nottingham's campus?
Polymorph any object? Doesn't that burn XP?
Another Interesting Video!
is polymorph forms usual for crystals containing only one isomer of a compound?
what is the difference between a polymorph, and an isomer?

@ki6eki i didn't think of it but i can see why you did
@ki6eki
No, but with that curly hair, he's a scarf, a hat, a cute female companion and a tardis short of a TV show...
suggesting professor to buy neo cubes and play with it. :)
How far does the polymorph definition go ?
Do for example austenite and martensite, or graphite and diamond count as polymorphs?
Is having multiple polymorphs of the same thing one way that slow release drugs work?
@superdau Yes.
You can patent molecules? I thought you can only patent the procedure to create them. Otherwise you could patent DNA, which is a terrifying idea.
What's the difference between this and isomers?
who would have thought mages are so smart
@JebusGeist Heheh! But will it turn the prof into a Dwayne or an Ace??
@ki6eki Hehehe. You are not alone :) I think at least all video gamers thought "sheep" when they saw the title ^^
@ki6eki no, you were not :P
@ki6eki I actually thought, 'self,' 'other' and then 'sheep.'
@ki6eki Right there with you!
soooo a polymorph is an isomer? yes?
@jordanmjk0 insane in the membrane, or insane in the brain?
@jordanmjk0 insane in the membrane, or insane in the brain?
@ki6eki Nope!
Although my mage has the glyph that lets me turn people into Penguins instead.
^_^
@periodicvideos
Any fish in that lake? :)
@ki6eki Yupp, and before I even watched the video I scanned the comments for my warcraft brethren.
@ki6eki
No, no you are not.
Am I the only one who thought "sheep", then "pig", then "turtle"?
cool
Moon is sheep, let it be written!
Poly-Waddle-Doodle all the day
1 person is insain
The Professor got a haircut?
Jealous forever
If it wouldn't put such a hurting on the scientific community, I'd like to kidnap the professor and just keep him in my house and ask him questions all day.
think you're confused? go talk to his barber
Q_Q he cut his hair
professor's hands shaking:\?
Aren't polymorphs shape-shifting aliens that feed on the negative emotions of their victims? I saw it in a documentary called Red Dwarf once.
