- For our updated Palladium video, we are mining the Royal Society archives for the story of its discovery - a tale of money, an asteroid and stolen samples?
The discovery was made by William Hyde Wollaston.
Royal Society (Romantic Chemistry Exhibition until June 14): royalsociety.or...
This video features Professor Martyn Poliakoff.

That's amazing, essentially literally touching history--the pieces of metal that FARADAY of all people used. Astounding.
"He was furious!" Professor Poliakoff was so emotional while delivering that line! A great scientist and natural hoster.
So cool to think Faraday actually touched those very same metals! Thanks as always for the glimpse into a wonderful past Brady!
Exactly. A lot of the viewership are school children who are just learning these things, and it's incredibly helpful to have it explained by someone who is an expert and who has done such a good job creating a visual depiction of these things.
Precisely. I for one am relearning Chemistry from a very basic level at the moment and I find this channel's teaching style most informative and extremely compelling at the same time.
I think I've been in front of the computer for hours now thinking of experiments I'll do when I get my lab up and running and I have these guys to thank for it. :)
You Sir, are inspiring. I wanted to attend school for extractive metallurgy, when I was young. But, growing up poor, abused, desolate, and low self esteem, I gave up. This is absolutely fascinating, and so complete. Exactly what I was looking for.
0:32 "Imagine that you've discovered a new element. What would you do?"
I'd name it after myself :P
Yeah, the way he explains all the chemistry related jargon is one of the best things about this channel. It makes some of the more difficult parts of chemistry easy to understand for anyone who wants to learn something new (:
I wish that video was more about reactions with palladium. (Pd)
Brady's channels are doing exactly what they are meant to do, making difficult science accessible to a large community of people, creating an atmosphere of learning and understanding that many of us could otherwise not enjoy and the videos are of course very entertaining.
What I don't understand is that many universities stay absent from this niche, since it is their core business to educate people. (I am aware of the classes that are being uploaded by other universities)
love the new video about palladium. still a lot to do since some elements only have 1min clip without seeing the actual element.
I feel very sad when I watch this videos from the royal society. why isn't this shown to the public? why do they have to keep it store so no one except a very few ones are able to see it?
isn't the royal society also responsible to promote science? really shame on them. just make a museum so we can all appreciate and learn.
thank god there's periodic videos.
A lot of young kids and people from non-english speaking backgrounds watch these excellent videos too. I think everyone involved does an excellent job in engaging such a wide and mixed audience.
It's such a fabulous thing that Professor Poliakoff has acess to the Royal Society Archives and that Brady can go with him to record a video explaining amazing pieces of history.
I feel privileged only to be a subscriber at periodic videos.
Perhaps he has acquired this habit because he does not want to impose any barriers to his students, some of whom may not be native English speakers or just might not know a given word.
I haven't attended any of Poliakoff's lectures, but I strongly suspect that he is a superb lecturer. I've had enough incomprehensible lecturers and instructors in my time to appreciate The Professor's clear, lucid delivery. His unique style and charming personality are important ingredients of Periodic Videos.
This was good, the background information on palladium and wollaston him self was interesting! good stuff :D
That splinter isnt a splinter at all. It is what is called a lamination or De-lamination issue or error. It happens in the rolling of probably any metal that has developed an oxide layer. During rolling or milling the metal will not develop a mechanical bond with the metal around it because the oxide layer. What your seeing the metal actually pealing away.
I hope you'll watch Tyler DeWitt's speech at TED, "Hey science teachers -- make it fun", and explore his suggestion to the fullest. I really think there are other mediums which more advanced students of chemistry can learn through with the pace they wish to learn at. I don't think I'm slowing anyone down. If someone chooses to view "less advanced" videos while being capable of much more, they are actually slowing themselves down. Interest creates a thrust for excellence.
i love you guys and thanks to all of you i rekindled my love for chemistry !!! i love you all, keep up your passion for science.
He's so romantic! "It's really like being back in his lab."
If you are really only 11 then i commend you on your thirst for knowledge and rather advanced vocab (at least compared to my own). Keep it up young one, you have slightly increased my hopes in humanity.
I can listen to the Prof talk all day, such an interesting person! And I'm willing to bet that package is worth quite a bit, it's nice that they show stuff like this, back in those days, it probably took a LOT of work to extract all that platiunum and palladium. Pretty darn cool!
Thanks for all the effort you always put in every single video
I think it's amazing that you get a chance to look through history with your own hands.
As an American I have to say I am fully envious that you have such tangible parts of history so accessible to you. I wonder if the Royal Society has a museum open to the public to see the wonders it has squirreled away? If not I think it might be a good way to entice more interest in chemistry by 'removing the magic' as it was. To show how things were developed might make it easier for people to identify with and thus try to understand the sciences more.
I can't believe you guys actually got to view some of Wollaston's original samples! That is so cool!!
I didn't know what those words meant, until I heard them from the professor.
Thanks Dr. Martin, teaching people English AND chemistry!
love your work.
Could you guys make another video about palladium, not about how it was found and its story, but about the phenomenon that surrounds the elements in the gold block, and the even greater phenomenon of palladium's electrons...
cause that is something that i would really like to know...
Add the historical value and the sky is the limit. Priceless really
You should talk more about palladium's ability to absorb hydrogen!
These historical videos are the best.
Thank you for the vids. I find it fascinating to listen to stories of 200 years ago, even if they are only 5 minutes or so. Give us some tie to that reality. We need to become curious and less violent to enjoy life. Cheers
Just a note.
that "splinter" that is mentioned is an artifact of the rolling process. That happens when the metal starts to stick to the roller as it is squished through.
Thanks everyone at Periodic videos! Helps me SOOO much with my chemistry GCSE, every video does!!
Truly fascinating. Quite a blast from the past, as they say.
Yup,
I work for the Materials Science department at Ohio state university. There's an undergraduate class where we do a lot of rolling and that sort of "defect" is very common. (especially on aluminum alloys)
It's an element, specifically element #46. Just above Platinum on the periodic table, has a symbol of Pd.
Hi Brady, great video as usual. I think it is time you upgraded your titles to HD - they look pretty blocky compared to your high def video!
Loving these no where else on youtube can you gat this...
I am far more interested in the concepts and ideas than in wading through the jargon. I am an engineer, an part of being one is an interest in the practical applications of ideas. I am not interested in any barriers (like terminology) erected to isolate these ideas (for exclusivity or other reasons). The professor has it right.
Would be nice if you included the special properties of Palladium in the video. Maybe it has a use today also?
Without a doubt, he has THEE BEST TIE EVER MADE!
You're right. I misread it at first, and I addressed an earlier reply who also noticed my oversight.
I agree. More of these types of videos!
Pure excellence. No BS. Just pure science.
Even if it is condescending, I am humble, because this is the muthafuckin professor.
Relax there, cowboy. I simply misunderstood him a bit, I didn't read through his message carefully enough. I quickly glanced at it and thought he said the professor is explaining chemistry/chemical terms in non-chemistry terms. The comment you replied on still has a valid point despite my oversight regarding pepsibookcat's comment, and that is that some young viewers may still have problems with some complex words or terms (were they related to chemistry or not). Don't be so aggressive. :)
Thanks for making them!
I didn't know what "Bequeath" means, I learned something new myself, and I excel in school pretty well. So I thank him for that...
i love these videos and the Professor's tie made my day!
I love all these videos. Always interesting, always informative.
You should have said thesauri instead of thesauruses. Both spellings are accepted but damn thesauri sounds so much cooler!
just woke up to a Periodicvideos
Hey Brady, why don't you use music?
I remember one video where you used an ominous sounding
background music that really tied the whole thing together.
I think you were with Destin.
Awesome to see the Faraday connection!
Is there any Palladium in Pallas?
Great vid. Maybe you could make a special about Professor's favoutite periodic tables?
Thumbs up so they can see
Not saying that you should, but could you still use a piece of that palladium for a science experiment?
Why no 1080p Brady? You always shoot 720i which looks bad.
Excuse my poor English but I actually didn't know the word bequeath so I appreciated professor for explaining that.
What are the properties of palladium?
So, what sort of pen and what sort of ink did they use to write on these Palladium sheets?
So is Cerium named after Ceres? As in the large asteroid/dwarf planet that people also thought was a true planet?
another fantastic Elements video! Keep up the great work!
Oh, I wasn't aware we all lived in Lithuania. I never thought I did, certainly. Also, please explain why one would "tech" about moles and free radicals.
I love this kind of videos!
Very cool. Thanks for sharing.
Palladium is one of the elements in the periodvideos picture. (:
i want to know more about this metal.
what kind of metal is it?
what kind of reactions can you achieve with it?
Very interesting as always. Great videos!
Can you make a video on how you do your hair in the morning?
I visited the tomb of Abraham Lincoln in Springfield Illinois USA. The curator said the ceiling was covered with Palladium. Maybe it was very thin like gold leaf. Regards to all you chemistry buffs out there.
Im from Brasil, yea, sometimes its a little bit difficult to understand. Subtitles are welcome!
Btw, the vids are awesome!
great video!
Great video!
palladium is my favorite
Love these videos.
guesstimating by the size of the platinum piece relative to the professors hand (lets say 7cm x 4cm x 0.5cm) it's about 300 grams, worth 10,000 pounds
i love his tie, great vid btw!
I bow down to you.
You can use it as a catalyst for hydrogenation of alkenes or alkynes.
Amazing. Thank you!
Imagine telling Faraday that the lumps of platinum and palladium he used, will also be handled by a group of scientists that live in the 21st century who teach chemisty and physics to more than 214,500 people and that all of his lectures and explanations on chemical reactions were seen 37.7 million times and that everyone in the world can watch those lectures anywhere, anytime... for free.
He'd be so proud. :-D
For a first look just look onto wikipedia then check its refferences.
Heh, touching the same metals that Faraday worked with... Man, might as well take a bite out of the apple that Newton observed falling.
Quite a bit of history there. Impressive! :)
Its atoms are unique, for example atoms of the element hydrogen have one proton, therefore it has an atomic number of 1, that is unique to hydrogen atoms only. Whereas the atoms of the element Palladium have 46 protons.
Effectively the number of protons an atom has allows it to be identified as a discrete element. On a periodic table, Atomic Numbers are the smaller values of the two shown, the other showing the mass number, which is the addition of the total protons and neutrons in an atom.
Could you cover the science behind the Super Heavy Island
Also, the most recent discovery of an element was element 117 in 2010.
Is that one of the duties for members of the Royal Society, to take inventory?
Good stuff.
one of my friends' last name is Woollaston, I'll have to show him this!
The professor always has the best ties. I'm honestly a bit jealous.
00:19 Typical phrase of an unboxing video, ''lets see whats in the box'' but now unboxing palladium
Yes Yes Yes lets see them do a video on that. Then we can think of more practical uses for it....
Amazing!
super cool video.
Yes, we'll call it Plutonium after the...D'oh!
7:25
Your platinum looks all tarnished and nasty; I'll take it off your hands if you guys don't want it anymore...
Tour of the professors' office? There seems to be some interesting things lying around
Wakes up - clicks sub box. YESSSSS
