Oh gosh, oh golly, are we excited! While we have been away from our building for three months now, our friend, the most wonderful chemistry teacher Andrew Szydlo, has sent us a gift like no other - an entire series of chemistry videos, filmed in his home and exploring concepts such as the chemistry of coins and photography, how a chainsaw works and even how to fix a leaking tap. We're so excited to watch these and to share them with you!
Now i understand why Andrew is so great on stage.. i think he is that person all the time.. Awesome, he is such a good communicator and the passion for the subject is almost touchable, even thru the screen.
This man was my Chemistry teacher. He was also ran the photography club, the automobile society, the beekeeping club, and was co-leader of a club called "Operatic society" which was in actual fact a chamber orchestra/fine dining club, where he bought nice cheeses for us to eat and played the viola. Man is a force of nature.
Such a wonderful person. Can do his childhood hobby as profession, highly educated outside his profession, he is a talented musician, has a passion not just to entertain, but to teach too. And he is such a nice person, constantly thanking his assistants, always being polite. He might be elder in his body, but has a youthful mind. And his overall clumsyness makes him charming. I wish I had someone like him tech me chemistry when I was a child. I'm sure I would have learned to love chemistry more that way.
I could watch him all day! It would be a privilege to meet him one day as I am just as passionate about science as he is. He is an absolute GENIUS as well as an intertainer! He is just amazing, may God keep him well!
Extremely interesting and engaging! I love Mr. Szydlo's videos; they're always packed full with chemistry gems :D also, thank you Oscar, great camera work :)
I am raising my daughter in the vain hope that she'll get into computer science, like her dad... unfortunately I've introduced her to the (admittedly amazing) Andrew Szydlo.... looks like Santa's bringing a chemistry set for Christmas! Keep up the good work, Mr Szydlo!
Andrew, Thank you for perfecting your special gift. This is a very tough day for me and I somehow came to this link and it brought a smile to my face. I can only imagine how encouraging you must be to Young students. I'm sure there are several who you've passed on your love for chemistry. For which the world is eternally grateful.
Only 9:30 in and I've already thumbed up the video. Andrew's enthusiasm is contagious. His ability to talk for long periods without many delays maximizes information transfer; I think I would have run out of things to say long before that point.
This man is excellent at story telling, excellent at public speaking and hooking the audience. Very entertaining, I want to learn from him, AMAZING TEACHER. Love this
@@Jimbojo Thats correct, but then again neither of them are 10^7. Ten thousand million (rounded up world population) would be 10^10 and 10 million million (10 old style billion) would be 10^13. Still a lovely video. PS In germany that older british style is still in use. "Billion" would be a million million while "Milliarde" is a thousand million
I don't have words intensive enough to express my gratitude. This video has inspired me to study equilibrium, acid/base chemistry, and electrochemistry! It is so fascinating to think of the relationship between lewis bases and reducing agents.
Thank you so much for reminding me of my passions...I wish my Chemistry teacher at Uni would have been more like you! I came there full of passion...only to leave after 3 semesters disillusioned. Anyway...keep up the good work...Love the videos...funny how we have the same passions...music...chemistry...fixing cars...
USA people and UK scientists (and in some other places, too) just use the same word for two different numbers, the seconds' being a million squared. He read that the world population was a bit above 7 billions, he just didn't remember that the source was likely using the USA version of the term.
10e9 used to be a milliard, 10e12 was a billion (1000000 e2), 10e18 was a trillion (1000000e3). This was used in the U.K. and some European countries. In the USA 10e9 was a billion, 10e12 a trillion and 10e15 a quadrillion. This caused no end of confusion, particularly when referring to finance, which was the main driver behind the adoption of the US nomenclature, even though the U.K. system is more logical being based on powers of 1000000! Of course, in science the SI units and prefixes were introduced (mega, giga, terra) to replace imperial measurements, this gentleman would have been one of the first to switch from imperial to SI nomenclature, I am about 6 or 7 years younger and I used both systems. It should be noted that there are still differences between US and U.K. measurements, particularly the gallon and temperature scales.
Thank you so much for this video series. Love it! Your teaching style is so retro and reminds me of my whacky A Level lecturer back in the day. Great way to remember “stuff’. This one in particular is Outstanding as I remember writing “Potassium Permanganate” for any substance that I couldn’t identify in my A level Chemistry exam. Happy Days :) Keep up the good work and keep it old skool.
About the magic medicine man? I'm pretty sure he brought that up in one of the RI lectures at the normal building, I think it was titled something like "the magic of chemistry".
I love your discussions & demonstration or chemistry - if you had been my teacher and I realised my passion earlier on in life, I would now either be a chemist or a teacher of chemistry ......I have read the The disappearing spoon , Uncle Tungsten & Gunpowder an explosive history and highly recommend them ...... I think you are surely one of the energetics - stay safe
So fantastic, we love us some LORD OF FIREEEE! \o/ Andrew Szydlo has given out the best gift in the form of these videos during this time, even cannibalizing his Triumph and holding Oscar hostage in his basement to provide us quality edutainment
Small correction: World population is measured in US billions, not billions. So it is 8,000,000,000+. The number of permanganate ions in one drop is about 1 million world populations. Brilliant video though, with a superb conclusion, so we don't mind Mr. Szydlo being human! 🙂
39:00 There's a greenish-blue virtual image (in the optics sense, ie not a "real" image) of the flame flickering above professor Szydlo's head in his shadow and I was wondering if anyone could explain what might be causing that and/or why it's a different color. does it exist in real life or is it maybe something happening with the camera? I personally think it might have something to do with that flask. I know there probably isn't a good answer for why the image is there (other than, "it must be reflecting off something in the room") but I am curious on maybe an explanation for why the flame's image is a different color or why it's a virtual image and not a real image.
15:43 - Unfortunately the professor has used the wrong definition of a billion here. From wikipedia: " This is the historical meaning in English (with the exception of the United States), and was still in official use in British English until some time after World War II." There are aprox 8 thousand million people on earth not 8 million million.
I love these videos you do, Im not a chemist, but have a pretty good understanding of many chemicals... should tell people that they can also use a few crystal's of potassium premagonate to purify water in a survival situation, now I just learned I can also make Oxygen as well! Excellent! I always carry a few vials filled with potassium premagonate and some glycerin to create a camp fire in the wettest conditions!!! Plus can purify water, and now oxygen! Haha seems like a great thing to have in a survival situations!
Plus can be used as an antiseptic too. My father's and grandfather's generation used to dissolve a single crystal in water to disinfect cuts and bruises.
@@jrctattoo Do not use potassium permanganate for rocketry or fireworking if you love your fingers and life. Mixtures can be unstable and dangerous. Also, reaction with glycerin requires certain temperature to ignite. In cold conditions, it will not work.
Dicyanin ( prepared by action of KOH + atmospheric O on a - y - Dimethylquinolinium salts ) ' sensitises silver bromide gelatine plates up to the red line a , with a strong minimal effect between E and F. Used as a red sensitiser for scientific work , but the prepared plates are not very sensitive . I swear that's dicyanin
What an amazing demonstration on the permanganates. Also the other experiments. You got me all fired up now for chemistry but it's time for bed. Thanks for this.
Why is it that home chemists can not make potassium permanganate crystals. They can go all the way to the solution and then they can't find a way to produce potassium permanganate crystals. Can you perhaps show us how to do this?
Unfortunatly Chemistry Teacher have a specific curriculum that they have to teach you about. They have to transfer information into your brain very fast and dont have the time to only do fun and exciting experiments all day every day. You cant just watch expeiments, you have to understand the underlying principles. Thats why students oftentimes experience science as a boring and difficult subject.
@@ksilebo yeah, except my teachers never did anything fun nor did they show proof of the underlying principles. they just monotonously droned on for the entire class period and then gave us tests for us to "prove" that we learned what they said. It was just all facts, figures, dates, and names. Not really science at all.
He was born not long after WW2 though, so he probably grew up with the long scale and unlearning things is hard. A lot of languages in mainland Europe still use the long scale to this day and the UK only formally adopted the short scale around 1975. In the long scale a billion is 10^12 instead of the 10^9 that it is in the short scale that has traditionally been used (and still is) in the US. Young people growing up now probably never have to worry about it, but it's quite an interesting messy thing to be aware of when reading older sources dealing with large numbers. You have to figure out where it was published, was the individual from the US or something more inspired by UK language usage and so on. It must also be quite confusing having grown up with the long scale and now everybody keeps using the short scale.
You can trust us to get 'permanganate' right but then fail at the hurdle of chemistry... We updated the thumbnail about 10min after the video went live, but RU-vid delights in mocking our initial incompetence.
@@TheRoyalInstitution Any chance you could fix (with overlay text) the mangled math? World population 8 billion (8*10^9) does not equal 8 million million (8*10^12), and other later mistakes of several orders of magnitude?
@15:57 8 billion is not 8 million million unless you're using the old English system. It's 8000 million. Also, 10^7 is 10,000,000 (10 million).10 billion is 10^9. So that part isn't correct either.
thechrisgrice I didn't know the English system had changed from a billion being a million million. I was taught a billion was a thousand million. It is in Canada and the USA. A billion 10^9? So 10 billion should be 10^10.
I would like to see if he could create P2P Methamphetamine, Then gas the oil with R-12..resulting a ph of 7.1.If he could do that,'' then he is a real chemist..if not he is just a explanation.
1974 in the UK. It's the long system. They too use the short system now where a billion is a thousand million but this gentleman probably learned it the old way.
The brits name their numbers differently than the american standard. Not the first time this has caused confusion. I believe the world population is 8x10^9(american billion), not 8x10^12 as he states in the video. What's a couple orders of magnitude between friends.
Great enthusiasm however pouring chemicals into the top of the large flask above his head with zero eye protection is rather on the irresponsible side,, especially given that he keeps knocking things off the table!
I love the guy, but he confounds the U.S. "billion" - a thousand millions, 10 to the 9th power - with the U.K "billion" - a million millions, 10 to the 12th power. World`s human population is some 7 "US billion", some hundred millions above 7000000000... Then again, it is just a small clerical error.
These words for numbers are a bit messy, look up "long scale" and "short scale". The UK used the long scale for a long time which is also still in use in much of mainland Europe for most languages, the UK formally switched to short scale around 1975 though. The US has traditionally used the short scale if I'm not mistaken and never switched from it. In the long scale 1 billion is actually 10^12. A trillion is 10^18, a quadrillion is 10^24, etc! For most young people growing up in the UK now that means that the short scale of 10^3 multipliers between words make sense, but this man grew up at a time before that. And depending on what Polish uses and how much he grew up with that language of his parents maybe that still uses the long scale to this day throwing more confusion into his brain. Results in quite a mess to be honest, if you read a billion in older sources or as a statement by an older person having grown up in those times you can't be sure if it is 10^9 or 10^12 until you find out where it was from and when it was written.
