yes, I was lucky enough to have a couple of passionate and generally good science teachers at school, though as I was already very interested in all things science, maybe I was biased. We did all kinds of experiments and even went on field trips to learn more about geology (which I found fascinating, and I am now a geologist...). There was also a TV show, "the curiosity show", that was meant to engage children with science and engineering. It was hugely popular in Australia in the 80s and 90s, with a lot now being put on RUclips by the original presenters. Regardless, we still need a whole army of Dr Andrew Szydlos!!!
Dear children, I just watched 107 minutes about sulfur and loved every second of it. Such a great and entertaining display. Thank you very much indeed, Andrew Szydlo.
He is the best science / chemistry teacher of all time. I wish i could see him in person. He is a great entertainer and holds your interest the entire time. I just love his lectures
when i see a video with andrew szydlo, i click i am not a simple person but i enjoy what i enjoy and this gem of a man infects everyone with his love of science!
Today I learned "brimstone" is/was sulfur. Always heard the word but never investigated deeper. Bless Dr Szydlo. I hope the RI passes the comments to the Doctor so he knows how many outside the classroom he reaches, inspires and enjoy his lectures even if we're not compelled.
One correction - scattering of light by particles of similar size to the wavelength is Mie scattering, not Rayleigh (which involves particles much smaller than the wavelength). Rayleigh scattering is caused by the gas molecules in the atmosphere, not suspended ice or dust.
15:58 Is the actor bellowing (as caustically as the sulfur vapor) because someone was too cheap to give him a mic? Or just showing off, as if he were giving the performance of his life…for the deaf? Royal Institution of London, renowned for lectures by notables and educational laboratory demonstrations for hundreds of years. Why oh why, by this time, isn’t there a permanent ventilation duct leading to the roof? Terminate it on a nearby wall, connect it to a 10m duct extension with a fan (and another fan on the roof). Worth the install if it’s used once a year for the odd mad scientist given to tormenting audiences with noxious fumes. Excellent demo and performance. RI also deserves a modest crew, further multi-cam capabilities, and distribution of these fabulously unique presentations so they can fund these ideas. (the end, dear children).

As always I love Szydlo lectures. However, I'm a bit younger than he is, and with each of his lectures here on RUclips I need a break to get my breath every thirty minutes or so. I admire his energy and enthusiasm.
so nice to see Andrew back , cant get enough of his lectures, Sulphur ? try top of Mount Tiede in Canary islands, three hours breathing in that, cleaned me out for two days after...lol
Andrew is my favourite Stinks. A brilliant teacher and entertainer, who brings Chrmistry to life for children of all ages. Thank-you all. Wishing everyone all the very best for 2024. 🙂👍
Most incredible achievement EVER made by the cosmos is taking a bunch of hidrogen atoms and turning them into something that ALWAYS let me speechless and stunned in awe... Andrew Szydlo. Dear Sir Szydlo, you are the most amazing person I had ever the honor to know. Thank you for spreading your endless wisdom.
Electric vehicles typically include a 12-volt lead-acid battery for auxiliary systems and vehicle control functions. This is a separate component from the main high-voltage traction battery, which is typically a lithium-ion battery or another advanced battery chemistry. so pretty much all cars contain a lead-acid cell, irrespective of their power source.
I can't find any reference online to the first known recorded example of sulvere in Sanskrit, it is one of over forty different names for sulphur like ghandhakah. I found one version as shulvarih or śulbāri. It is common for Europeans to mistake ś for s in Sanskrit transcriptions. Is it from the Rasashastra chemical treatises of the 5th century AD and after? Sanskrit is an ancient language but not all of its words are. The Latin origin of the word, as sulpureus describing a sulphurous river, is known from before 169 BC as it was used in a poem by Ennius. Proto-Indo-European *sulplós has been proposed as the origin, meaning "burn-stuff". As far as we know there was no contact between Rome and India before the first century BC. A Sanskrit compound word (copper-enemy) seems unlikely to be the origin of the Latin word.
I had the same reaction when I heard this part, especially when he prefaces it with the statement that Sanskrit is "the oldest language in the world", which is an absurd statement for several reasons. I generally like it when lecturers talk about the etymology unfortunately it's fairly often poorly done, like in this case.
@@Maaaaaaaaaaaaaaartin Sanskrit is perhaps the oldest continuously used language in the world due to its preservation as a liturgical language in Hinduism. It is certainly not as old as is claimed by some Hindu enthusiasts. 3,000 to 3,500 years before the present is the furthest back most legitimate scholars will push the history of Sanskrit. Certainly not the 5,000 years before the present mentioned in this video. It is also like implying that "Internet" is 1,000 years old because it is a word used in English. The Sanskrit for Internet is apparently antarajālam.
I am very sure that Andrew Szydlo himself could have performed those simple sulfuric acid demos perfectly well; there was no need to fly someone in from Italy to perform the demos, and for commentary on what was happening at a chemical level! Having a BSc in Chemistry, I could have performed those demos myself- it is hardly cutting-edge and ultra-complex Doctorate-level research chemistry! Watching Andrew brew up a cup-of-tea-with-sugar now and again for his medical condition (referring to one of his previous chemistry lectures) is all part of the charm of Andrew's style! The younger guys are too serious in their demeanor, and are as entertaining as watching paint dry! Andrew's old school style of delivery is what we need more of!
Isn't it amazing we who live in the modern world are doing the same thing today as alchemists used to do back then? In today's fancy words, we call them "Alloys" and add modern techniques and knowledge to them. In today's modern fancy term, we call them "Chemists or Inventors". What the Alchemists trying to achieve was to invent a procedure to develop a substance that has a higher beneficial importance to humans than its constituent parts. Isn't it what we are doing today in the modern day with the benefit of modern techniques, technologies, and knowledge? I am glad Dr. Andrew brought this forward.
I feel very old when professor Parmeggiani mentions how old the reagent bottle was because the label is engraved; I recall almost all of the bottles in our school labs had the labels etched or engraved into the glass.
If only Andrew had been my Chemistry teacher 50 odd years ago, I would have stuck at it- but alas my teacher was so uninspiring. I am sure any child in Andrew's class would love the subject.
Sulphur in modern chemistry is very useful. It's used in matches, insecticides, and fungicides. But the connotations in ancient an even in today's belief systems cannot be underestimated...
Domaine du Vieux Vauvert Vouvray - a very drinkable medium-dry (actually medium-sweet) wine. Recommended, unless you’re asthmatic and allergic to sulphites. A tenner from Waitrose.
P.S.S.S. I've learned more in the last hour about sulfur, than 10+ years of watching youtube chemistry content, religiously. I don't know if I'm ecstatic or should cry. Either way, thank you so much.
My father, born in 1908, had a Saturday night routine, along with his brothers and sisters. After the weekly bath, everyone was given a spoonful of blackstrap molasses and sulphur. That was supposed to keep them in good health.
👍 I have learned a lot from Prof. Szydlo. I really enjoy the videos. I think my favourite one was the one where he was explaining that candles burn with a sooty flame and petrol burns with a blue flame in a motorcar engine. 🔥 I was testing that out by holding a tea saucer above a candle and observing the black sooty deposits. Until my wife said "What on earth are you doing? Making a filthy mess." "But the professor says..." said I. "Never mind" said she. "Now do the dishes." 🚙 Whenever we drive around in our Toyota Yaris I often envision the thousands of blue flames in the cylinders, and this is oddly satisfying. But I don't mention it to my wife or she would probably say that It's my turn to pay for gas, and she would probably be right. 🌋 As for the volcanoes, they remind me of an incident that happened with our microwave oven. I saw on RUclips that you can boil an egg in a glass of water in the microwave as long as the egg is completely covered in water. Either the video was wrong or I did it wrong because suddenly there was a loud BOOM from the microwave and the bottom of the microwave was covered in eggy water and the walls and ceiling of the microwave were coated in cooked egg. Fortunately my wife was at work. But I spent a miserable hour cleaning out the microwave before she got home from work. From then on I haven't believed everything I see on RUclips. But I do believe 99% of what Prof. Szydlo says, with the remaining 1% being that he knows what he has done with his tea 🍵. Cheers from Canada :-)
Re: microwave-boiling eggs in the shell: They explode because the water inside the egg boils, yet has nowhere to expand. Either use a lower power setting or salt the water-minimum 1/4 tsp. per 8oz (240mL)-to slow down the heat transfer.
@@Jszar A good explanation. Thank you. But I think the answer is not to do it. The explosion makes so much mess and it is so difficult to clean up that it is not worth the risk. Especially when there are so many other ways to boil an egg :-)
I also have to say, it's nice to see some others incorporated into the lecture. I've honestly been worried about when Professor Szydlo has to give up the mantle. Those are big shoes to fill. Professor Parmeggiania has my vote

Andrew is one of the treasures of our species.
Don't get me wrong, I think so too.
He keeps you on your toes so to speak 😅
Teaching to an extremely receptive audience is far removed from teaching on a daily basis…..
@@peteypopsHave you ever wondered what makes your audience receptive and engaged? Excitement is contagious.
Dear children, I just watched 107 minutes about sulfur and loved every second of it. Such a great and entertaining display. Thank you very much indeed, Andrew Szydlo.

Dear children this guy is a legend when he shows up, just fantastic. If we all had teachers like this chap
He's like the Bob Ross of chemistry. Just didn't become known until youtube.
when i see a video with andrew szydlo, i click
i am not a simple person but i enjoy what i enjoy and this gem of a man infects everyone with his love of science!
Dr. Szydlo is such a fascinating teacher. He is a treasure to us all.
I have watched a lot of the RI Andrew Szydlo videos for revision in my chemistry GCSE and they are fantastic. Very helpful. Thanks Andrew.
Today I learned "brimstone" is/was sulfur. Always heard the word but never investigated deeper. Bless Dr Szydlo.
I hope the RI passes the comments to the Doctor so he knows how many outside the classroom he reaches, inspires and enjoy his lectures even if we're not compelled.
Trust me he knows! and the amazing Ri people always sends him all the wonderful comments.
Andrew Szydlo is one of my most favourite professors. The other one is Prof. Martyn Poliakoff.
I should like to add Peter Wothers, for me he is inspirational. (I'm a 75-year old chemistry student.)
A video of Mr Szydlo recorded on my birthday? This was a better birthday than I originally knew!
Christmas wish is for TRI to have Szydlo do one of these for every element on the periodic table!
A line from an old metal band, Tourniquet:
"Johnny was a chemist's son but Johnny is no more. What Johnny thought was H2O was H2SO4."
The only thing missing was the barking dog, but other than that, another great, interesting and informative lecture by Andrew and the team. Well done
Such excitement and enthusiasm for a subject he’s obviously studied endlessly. Absolutely brilliant as per by the RI 👏🏻👏🏻
Nice touch to include literature.
One correction - scattering of light by particles of similar size to the wavelength is Mie scattering, not Rayleigh (which involves particles much smaller than the wavelength). Rayleigh scattering is caused by the gas molecules in the atmosphere, not suspended ice or dust.
Love Andrew! His showmanship and detailed history and explanations are wonderful❤
Merry Christmas with FIRE!!!!!

You are awesome!!!!
Apparently, he invited an Australian backyard chemist to give some demonstrations and he responded, "Ugh! No! Not yellow chemistry!!!"
;)
Haha😂

Andrew Szydlo allways delivers
More...more ...more ! I love Andrew - fantastic!!!!!
That Tyndall effect demo was something special, never seen that one before.
Very powerful, I thought. Shame it's not used more.
so nice to see Andrew back , cant get enough of his lectures, Sulphur ? try top of Mount Tiede in Canary islands, three hours breathing in that, cleaned me out for two days after...lol
Sul'phurous may be the adjective I learnt at school, but sul-fur'ious is a great variant 😂
When the devil gets really mad, he gets sulfurious.
Prof. Breathless :)
Quite adorable, his lectures. Privileged to have been able to watch and admire him
How i love this man ...
Hugs from Poznan Pan Szydlo.

I've been listening to his lectures for years via youtube. I'd love to hear him teach in person one day
I love this guy. I wish my chemistry teacher was half as good.
Love Dr Szydlo, It's been too long! Thank you🙏
Great effort by the great professor and his brilliant team members. It is all awesome. Thanks and regards!
I could not imagine how many current and future scientists as well as interest in science this man has inspired
I couldn't help but feel I was listening to Professor Farnsworth. If he came out with "good news everyone" I'd have melted.

What a legend. All teachers everywhere, take note.
Would have been a funny an interesting density experiment to have used Sulfur hexafluoride.
I was just binging Andrew’s presentations, and a new one just appeared! Christmas!
Thank you for this lecture, it's so cool♥️♥️♥️
Always good to see him again
Andrew, brilliant as always.
Not too keen on the readings. Poem was pure cheese!
Good job Andrew - super engaging wish I had smell-o-vision 😂

perfect for Xmas Day
Hey, Andrew, what has Terry the Plumber been up to?
my dad told me a story about acid. "Little Willy is gone now Little Willy is no more what he thought was H2O was H2SO4."
I can only imagine the odours in the lecture hall, must have smelled like it was cabbage & sprouts night in the canteen... :P
Legend
it’s nice that the best potions professor at Hogwarts tried to teach us muggels something
Little Johnny was a chemists son but Johnny is no more.
What Johnny thought was h2O was H2SO4.
Just super
I also have to say, it's nice to see some others incorporated into the lecture. I've honestly been worried about when Professor Szydlo has to give up the mantle. Those are big shoes to fill. Professor Parmeggiania has my vote
over an hour and a half long and i'm still hoping for some fast paced andrew action
I think they switched his tea to decaff
Thanks for using the actor to give emotion to the reading. I appreciated it.
What do you get if you mix a poet with a chemist, A Szydlo !
What do you get when you mix Szydlo with a Terry? A very violent reaction!
(it's a reference to some of his home videos)
