Easily one of the best and most organic outros I've ever seen, to an absolutely great video. Thanks!

I was literally grinning through this whole video because it just exudes pure joy and excitement.

Thanks for the memory, The simplest crystal set I made was a 1950's Germanium point contact diode strapped across an old telephone magnetic microphone, with an aerial and ground attached to each side of the diode. With it, and no amplifier, you could hear the local AM radio station right through our house. It still works well, decades later. Crystal sets were the seed which inspired me to earn an Amateur Radio license, and to choose an electronics-related career.

Finally, the Mighty Moriarty!

Always happy to see Professor Moriarty. You can't not admire his enthusiasm.

Yea, I still remember when I build my first crystal radio set (using electronic components, not pennies) and finally getting it to work and then spending hours listening to Radio Moscow (the transmitter in Kaliningrad was powerful enough to be picked up in Denmark and happened to be in the right frequency range). I can still remember how puzzled I was of how poor the propaganda was, it was completely unbelievable even for a 15 years old kid (it was in the 80'ties)...

Man Phil is such a gem

Still have my fathers crystal set which he built when he was a boy in 1932. Found it in the loft of his house after he died in 2011. I remember building crystal sets when I was young. There is something magical about radio, such happy memories.

"London Calling" the best way to start a video 😍

This is just wonderful to watch! I'm a scientist myself, I know the fascination first hand. It's so engrossing to watch Prof Moriarty!

Me and my brother made a crystal radio from a commercial kit decades ago. We put the antenna wire in the attic, along the whole length of the house, and drilled a little hole in the ceiling to let the connecting wire through. I haven't been to that house in ages now, but I bet that antenna is still there. The thing worked like a charm btw.

This teacher is an absolute blessing

that ending got me right in the feels.

Lovely. I just cried during a video about a radio.

Professor Philip you are an inspiration to younger generations of engineers. There is the time when we doubt ourselves but it only takes one video like this to get us back on the track. Cheers!

Ten years of my childhood in one video! I made many crystal radios, based largely on MRL designs. (Modern Radio Laboratories - which was neither a laboratory or modern, but just an old man who had spent a lifetime maximizing crude radio circuits and determining the most desirable wire gauges, insulating materials ((double cotton covered)), best galena crystal designs and cat whiskers (( a rod on a ball joint with a wood knob at one end and a spring at the other from which descended a high nickel wire of about 30 gauge to tickle the crystal)), etc.) One of his innovations (probably not his invention but he was insistent on it) was a second .365mf variable capacitor to tune the ground. It made tuning the set a lot like an early TRF Radiola - move one dial a little, then move the other a little... But on the Mexican border I could hear Chicago and occasionally the BBC! But only after midnight, when the local station went off the air. During the day it was the local station all across the dial. High impedance head phones were a must! Or connection to an amplifier, as you show here. I went on to one tube radios (valves in Britain) built from tubes I salvaged from old televisions found in the trash, and regeneration was like a Black Art - where a radio that had only a half dozen stations or less would squeal and suddenly have thousands! Ten 9-volt batteries taped together and wired together providing a 90 volt plate bias. Never went far into multi-tube sets because I couldn't work out resistance coupled stages. And then I grew up. I still have a lot of the parts, the wires, the coils, the tubes, the capacitors, the headphones, etc. in the garage. Hope I have a chance someday for a "second childhood" and to play with them again.

I like his enthusiasm :) This reminded me of the time I built a cat whisker radio back in the early '60 when I was a young child.

The ending was emotional. A fitting music too !

Love seeing Professor Moriarty's consistent passion for physics. These are always interesting videos but this one made me especially happy with the fun experiment and trip down memory lane. Nice hair! The synchronicity of that song playing was pretty sweet. Cheers!

Phil is just an amazing person. I love him.

Thank you Prof. Phil. My stepfather bought this book and the required components when I was 10, but we never got a radio to work. But trying to got me into electronics, and I’ve been in the business for 35 years now - with far more success than that old transistor radio. I may try again now, and would love to recreate your cat’s whisker on a penny rectifier! 😃

I LOVE radio! I'm a amateur operator in the states. I once talked to a gentleman in Ukraine from near Kingston, Ontario CA. The radio was built from two broken radios, and the antenna was home made. One of my happiest moments in radio. Has Phil ever thought about getting his license?

This is best thing ever I smiled like a little kid again. I built one out of a kit as a youngster and can so relate to the joy this brings.

Hi, Prof Moriarty. Was in your lectures 2005-2008. Just hearing you talk brings back so much physics notes in my head hahaha. Thanks for your undying enthusiasm.

Omg that got seriously emotional. You couldn’t have planned a better song played through a better radio for a better scientist. Beautiful

I love his enthusiasm!

This video really brought up childhood memories. Loved listening to the AM radio with my crystal receiver. I did use a Germanium diode for greater sensitivity (Ge 0.2V vs Si 0.7V) I remember reading they even old corroded razor blades instead of the penny during the war. Great video as always from you guys.

One of the best videos I've watched for a long time - I've had a life long interest in physics, electronics and as a kid I just adored my "sciency" Ladybird books. happy days, great memories.

There couldn't have been a more suitable song. Absolutely amazing!

Wowzers. Watching this gave me the screaming-hebbie-jeebies; I used the same book and made the same project when I was a kid in junior school 35 years ago! Just ordered the book again from amazon and cannot wait to recreate this stunning piece of wood-electronics.

I had that ladybird book as a boy! I treasured it and seeing the pages again brings back lovely memories. My copy is long gone now - time for a reprint ladybird!

Hey Brady, we are having the time of our lives watching all the great content. Thank you all the professors for spreading knowledge for everyone.

This was one of the best videos I’ve seen in a long time. Thank you, Brady

I had this book as a kid, and like the professor I built my first radio with it. Strung the aerial out of my bedroom window to the washing line pole at the end of the garden. Built the electronics onto tacks hammered into a piece of wood. Used to listen to Capitol Radio on it.

This is the BEST physics VIDEO ever . I also JUMP on my room when I was kid and my first germanium crystal radio picked up the signal!!! And for the same reason I ended up at CERN 20 years after .. and still listening SW radio . GREAT VIDEO than you!

I can somehow imagine how Phil is jumping around as an adult

OMG that book. I still have my original copy from 1975. As a child it was clear I would be an Engineer like my dad but at 10 years old I knew electronics was the future for me. So happy to see you share this with us.

oh man, I'm gonna cry, y'all

He is always so excited when he does his videos. No doubt he'd be an awesome instructor.

Making me nostalgic for Phil's lectures!

As a kid (circa 1960) I used to build crystal radios into filbert nut shells. It was great fun and got me started in my career in electronics.

Simply a brilliant video. Thank you for making them.

This is really fascinating, you guys should do a whole series on radio.

I remember building a crystal radio as kid sometime in the 90's... I think 93 about 10. I recall opening the kit, and desperately trying to figure out what type of batteries, finding out it doesn't take batteries. With incredulity I thought, how is this going to work without a battery. It did. I picked up many radio stations. It gave me goose bumps to begin to hear the ghostly sound of the radio stations, and become louder as a tuned in. All with a few items: simple electronic diode, piece of toilet paper roll like cardboard with wire wrapped around, small crystal earbud, and various wires and one very long antenna wire, and an optional variable capacitor for that method of tuning as well as a coil wire so you could try the two different tuning methods. So simple and basic that it was the first time I realized it wasn't complicated magic trick, but very basic physics that explain radio reception... and to me the simplicity was the real magic.

The perfect blend of drama and education. Well done!

the slideshow during the Green day song was spot on. that song might as well be named the slideshow song. had me dying

Brady, what a beautiful video! The joy of discovery should always guide our lives. It can make us feel like kids even when we're grownups

That ending was beautiful.

My favorite video you’ve ever made this was awesome

To do back of the envelope maths, and make an RC circuit out of simple materials by hand is just awesome. This is at the core of science when a little thing excites you as much as the big stuff.

Just plain great fantastic stuff. I'll build that with my son this weekend. I remember building a crystal radio in my forest village when I was 10 (that was last century): could hear the town 100 km away: civilization!

That was awesome !!! Thanks for the video ! That was like watching PBS' NOVA as a youngster !! Thanks guys !! Really made my day !!!

Unexpected beautiful ending.

My favorite professor at Sixty Symbols, others are awesome too though.

Only a few hours ago while driving home listening to the latest unmade podcast I thought to myself, Phil Moriarty hasn't been in a video for a while. And then I open KZread and there he is.

My God Brady you've done it again. Thank you Phil for allowing science to well up my heart

As I type, I can hear, very faintly, Radio Moscow on my otherwise idle amplifier. I live right next to Woofferton transmitting station, the last remaining short wave site in the UK, which played an important role during the Cold War. Its location is significant because it's next to Clee Hill, and it just so happens there is nowhere higher in a straight line between it and the Urals in Russia. Apparently, old people say they used to be able to pick up Radio Moscow through their fridges, in fact there's a pub in Cleehill village called the Kremlin. Fascinating stuff.

Brady, great job with that ending montage.

I have an honours deg in physics (years back), and the penny diode was a real surprise! How neat! I also have an amateur licence in Canada. Great video.

Ladybird book of the Hangover is my favourite one. Had a chrystal radio kit as a kid (Well, it was part of a Tandy's electronics kit) thankyou for explaining how it worked!

Well done Brady on taking advantage of the serendipitous song...

For the love of science! I kept my crystal receiver that I built in a jam jar, using a toilet roll cardboard tube as coil form. The feeling you get when you hear the first signals is amazing. When green day came on, that montage made me tear up. Just because I share the joy of radio and discovery. It never ages.

Brings back memories of my dad teaching me to build my own homemade radio in the early 1970s.

Ahh the Green Day song at the end was Perfect!

The best video yet!

Brady, things like this just make my day, thank you :)

A crystal radio opened the door to science for me as well and a life long love of radio

Really liked this video. Grass root, basic science. Easy to be forgotten when we all have laptops and smart phones.

I built one if these as a kid but for some reason, never became a Nottingham physicist. Honestly, I’m amazed that there are still amplitude modulation broadcasts.

as someone who's always been interested by electronics and more recently radios, when i found out the simplicity of an AM reciever i was very surprised. i also remembered when my friend had decided to try and build a guitar pedal and ended up creating a radio reciever, turns out they were using a silicon diode and im not sure of the rest of the components they had and how they had wired them. before i knew about radios i had no idea what could've been going on, and now that i know what's going on, i wish they had kept it!

Phil ..... Great video (and Brady also). For myself to was a Boy Scout merit badge book. This lead me into a career in electronics and Ham radio as a vocation. Keep up the good work of inspiring the next generation to seek out and find joy in the physical world. In Ham radio speak, 73 de K1PU

This is the coolest thing that I've seen today.

Love Professor Moriarty

This is the spirit, very inspiring! I hope to see more of this in academia
