  1. If anyone’s interested, the back of the envelope reads: “For the benefit of the St. Petersburg Board of Guardians of the Sisters of the Red Cross.”

  2. I have to say though, if I would actually come up to Mendeleeff and say "Hello, I'm Professor Poliakoff" he would probably just scowl at me and accuse me of identity theft!
    And it wouldn't be hard to prove, I'm as bald as a mole rat.

  3. probably Mendeleeff sent one card in 1901 and some one "for some reason" added another card later to the envelope, which was signed in 1902

  4. @zythepsarian me too. Even though i was a chem student at university for two years before changing to Computer Engineering 🙂
    The people i studied chemistry with felt like true peers, and for the first time in my life i was among mainly similar minded people. I had to quit to follow my passion, but i still love chemistry as a hobby.

  5. Mendeleev, Karl Marx and others had big beards. Were they godly men? This question irks me. Would someone throw some light?

  6. @Sockheadableful
    Why is everyone so adamant about calling him "The Professor"?
    It just seems so unnecessarily over-the-top. His name is Martyn, and along with Brady makes interesting videos on youtube about science,

  7. How can I obtain one of Professor Poliakoff's business cards? You could have a contest & make that the top prize…

  8. Fascinating, from chemistry comes history. Holding Mendeleeff's business card is maybe the closest thing someone today can get to meeting him, somehow brings the legend to life.

    However, if he were alive today, I wonder how he would react to this video: "It's been 110 years and my docs have been dropped on YouTube?!" 😉

  9. 3:20
    "[…]Scientists in different countries were already communicating, collaborating together…"

    For me this shows the truth progress that education and will to discover our world can do to you, you don't care if someone is jew, black, white, speak your language or not you want to share and collaborate because that's what scientists do and they understand that we, the human being specie, should work together so that our future can be prosper.

  10. I'd certainly love to hold Mendeleev's Business Card ! It'd be a "terrific" experience [as the Professor says] !! You're very lucky Professor and you too Mr.Brady !

  11. I LOVE this Channel , but it has become more of a history than chemistry channel :/
    I miss the days when i was so eager to see a new experiment , compound/element wise… now it's all about history, with less talking about compounds and what not 🙁

  12. Hey, I have one of those. From Mendeleev, right?
    Unfortunately, I left it on the beach and when I went back, it was gone…

  13. And all that archival material comes to a dead stop upon the advent of emails – unless someone collects email files; but no handwriting, no stationery, no postage, no character.

  14. @tradecycles You should see it in light of the times. Science hadn't explained enough about the natural world yet. Also, (nearly) everyone in those days was born in a religious family and indoctrinated.

  15. @tradecycles The question if they were godly men should be seen separate from the beard issue. Back in those days, a beard was "the mark of a man" and fashionable. Just like hats were fashionable in those days. Shaving wasn't as widespread a practice in those days.

  16. Cool historic business card. My great Grandma Blanch sent me letters with homemade cards when I was a kid. I kept them all in my archives.

  17. sounds the Prof is gonna have to order another couple of boxes of cards for the next flood of correspondence he is about to receive.

  18. Thomas Edward Thorpe (1845-1925). Wikipedia has nice group photograph of Thorpe with van't Hoff, Mendeleev and others. Does anyone know them?

  19. Why does it seem everyone back in the day had beautiful handwriting and now everyone's sucks. I write all the time but mine is awful so I know it's not the whole "the more you do it the better it gets" thing…

  20. @hoboX10 Actually it is the more you do it the better it gets.

    BUT back then you were expected to write neatly when you wrote to others, if you looked at his general notes to himself and such they would be just as untidy as your writing.

  21. Hmmm… I have a feeling Mendeleev's card may actually be a visiting/calling card, not a business card, there is a certain difference.

    I expect that Dr Duncan couldn't under the rules of social etiquette of the time go to Prof. Thorpe without a formal introduction like this, so it was probably more a matter of social propriety than shyness that required him to get this letter.

  22. @periodicvideos Are you sure it says "12.1.1902"? It looks more like "PF", or "Pour Féliciter", which was written to say "Happy New Year". The postmark says Dec 29, 1901, so it wouldn't make sense for the card to have a later date written on it.

  23. After being introduced to aerogels I would like to request it as a future topic. Perhaps you guys can make some? =)

  24. Let's see Mendeleev's card… Look at that subtle off-white coloring. The tasteful thickness
    of it. Oh my God, it even has a watermark…

  25. @culwin no way man, a blue eyes white dragon would never cut it for that thing… hey professor, i'll trade you my slifer the sky dragon for that

  26. @tradecycles i think that believing in good is a good thing, but not like the mainstream way, but like you want to stop doing something you invent a god that prohibits for example smoking. I think Marx at a good explenation the "good phenomena" and that is that you need a drug to help you…. maybe to get smarter, stronger, fatter, healthier, unhealthier and the list continues, basically beacuse you dont have the balls to do something you "virtualy" create more "ball"

  27. @rietveen26 i agree, its a fascinating subject… you should see what i wrote to Tradecycles, thats my main theory about religion, its just a matter of having someone to look up to

  28. @rietveen26 i would also like to add, im not a complete atheist as i partly belive in Russia….. yes quite a strange thing to belive in…. and maybe a tiny tiny but putin

  29. At the end, with both cards side by side, I had a pinch at my heart. One day, the professor's card will be sadly resting in the archives also…

  30. Is it really safe for him to be touching paper with bare hands? After all the oils will cause it to decompose.
