0:55 WOW. How have I never seen this before? I've never even considered why the two are always perpendicular and not e.g. in the same plane. Such a great animation
Thanks! That took about a day to make... potentially because I started in PowerPoint before biting the bullet and buying After Effects. Glad you liked it!
0:55 I think this is the first time I've seen someone properly explain how EM waves are generated. And I have a STEM degree lol. Also came over from Tom Scott, been watching through your backlog the last few days
I am in the exact same boat. I'm part way through watching every one of your videos because they are just so amazing and I've really enjoyed learning so much! I'm so glad you collaborated with Tom
@@jacobblomdahl557 Jackson's _Classical Electrodynamics_ is considered _the_ textbook on electromagnetism for postgraduate students (and Honours students in Australia)
I was absolutely blown away by that animation. I also had to pause to exclaim my excitement when the host explained AM vs FM information coding. "I studied physics for 5 years and I didn't know that what those stood for!"
0:47 I can't believe that none of my science teachers have ever explained electromagnetic waves this way. Thanks mate. That was such an elegant explanation..
I'm so glad Tom Scott hosted you on his channel! If he hadn't, I never would have found this channel or any of its wonderful content. I look forward to the next video!
Hey! So excited to see how your channel evolves and it's nice to be part of the community relatively early on. I'd love to help out with audio or anything related to France if there's ever the opportunity. All the best !
This is the most intuitive and comprehensive explanation of what radio waves are I've ever seen, and I went to tech school to study radio transmission theory
Amazing video, amazing explanations, can't believe I haven't seen you before and can't believe you aren't getting the rows you deserve.... Keep it up! I know I'm gonna keep watching!
This is really interesting, thank you! I grew up close to the ASTRON and the old CAMRAS in the Netherlands, but somehow never really grasped how it worked. Now I know! And man am I jealous they let you up there!
During Apollo 13 the Honeysuckle Creek tracking station near Canberra couldn't pick up the LEM's faint radio signal. The engineers managed to reconfigure the dish of the Parkes Observatory to receive the signal from Apollo 13, helping in the rescue of the crew.
Space communication is usually done through the phase domain. It can allows higher data rate. Frequency and Amplitude can be used but are next to useless when factors such as the Doppler effect and atmospheric noise cause huge changes in these properties that would be way too power expensive to predict on the spacecraft for every transmission and reception
Absolutely wonderful presentation and filming. Your ability to communicate details is exceptional. So glad Tom Scott introduced me to this channel. Looking forward to your next video.
The animations for radio waves were excellent, I've never seen this topic explained in such clear and simple way. Very grateful to Tom Scott for shining some light on this channel. Godspeed, James!
You left out phase modulation, but that is probably going one level too deep. It is mostly used for space comms. Because the amplitude modulation can suffer badly from noise, and the frequency can change a lot (Doppler shift), but phase modulation is effected less.
Neat video! But there’s more to radio than just AM and FM, there’s also phase modulation, which is arguably a special case of FM. Then there’s composite techniques, like quadrature amplitude modulation, which is used in high-tech radio protocols like wifi. The thought that FM carries more data than AM is mostly misguided, both have a data throughput proportional to their bandwidth (measured in Hz) and their signal to noise ratio, as per the Shannon-Hartley theorem. Same for noise immunity, to some extent. FM broadcasting stations are at higher frequencies than AM stations, and so they have a lot more bandwidth to put the same audio data through. If you crammed the same data in AM and FM channels of equal bandwidths (say, 44kHz), with the same SNR, you’d get similar levels of fidelity. Interference from lightning and such would effect both modulations, but in different ways. QAM, which is a form of AM, is used for higher speed wifi protocols, but when interference over a certain level is detected, I believe it switches to PSK, phase shift keying. If you’re interested in low power long range radio, look into LoRa.
Content is great, audio is great, the number one thing to improve is the video. For example the focus, mininmal colour grading and white balance, exposure (check how your face is exposed, often too bright or dark), and especially choice of lens. Usually the field of view is very wide, your face is hard to see at all. I have no doubt this will keep improving with more experience though!
*nitpick* 5:15 when moving the bulb, you're not changing the amount of light being emitted, but you increase the volume of the cone the same amount of light is being emitted into...
You should have a look at the Harold E. Holt naval communications stations. Normal people who dont work for defence or raytheon have regularly been granted tours inside the building at tower 0. Plus how the VLF works.
I'm literally working on getting permissions sorted for that right now! Going to try do it as a collab with the submarine guys too, maybe get onto a collins class. Wont be getting published until mid june though so make sure to stick around!
@@AtomicFrontier I dont know if subs come up to the pier there. It'd be worth trying to get into the RAAF Base too the bunkers are neat there, plus the KC 135s stationed there sometimes. If you wanna include some current issues in the town I'd make note of the Gascoyne Gateway plan for a deep sea port and the threat of industrialisation in the gulf. I've lived in the town my whole life if you have any questions too.
Quick question: are the parabolic antennas used to SEND radio signals? I thought they were only used to RECEIVE (because, as you explained, they concentrate the signal into one spot).
They can be used for both! One of the cool things about radio (and lots of physics phenomena) is that you can run it both forwards and backwards. So you put current into the 'receiver' it then works as the emitter. The parabola then re-directs the concentrated signal source into a single direction... ideally where your space probe is currently located. Hard to show without a diagram, but if you look at 4:56 you can imagine that playing forwards (as a transmitter) and backwards (as a receiver). Hope that helps!
The Arecibo telescope was used for both sending and receiving, and could be used as a RADAR to study asteroids. I hope we get something similar to it again, because while it wasn’t the only radio telescope with transmission capabilities, it was still pretty unique.
Does the sugarscoop really work the way it is illustrated at 4:01? The shape seems to me more like it would bounce signal off the lower scoop, then off the roof and then down into some receiver...
Hi! Yes that's a slight simplification on my part to keep the video flowing. The way you've described it is spon-on! The receiver is inside that mesh covering in the middle of the flat section. It you 'unfolded' it it would resemble a single long horn.
I hope you make some flat earth (FE) debunk videos. Seems like you are Australian and the Southern Hemisphere (SH) is the best FE debunk cos of the Southern Cross (SC) constellation. It never rises or sets and just goes around in circles, staying in view at all times (at night and viewed from > 30° South). This is something we can all see (outside) that is not possible on a FE (but the NH is where most FEs are). But there are FEs from Australia on UA-cam and I trolled them about the SC but they don't respond cos they can't explain the SC circular path on a FE. Since I have been posting debunk comments (like this one) I have learnt way more about our ball earth geometry and space geometry. I have 20 FE debunks that we can all see outside. Some with a telescope though. I will post them to you if you want.
He likes CGP Grey, and was introduced to me by Tom Scott's January break full of wonderful creators! Thank you UA-cam gods!!!❤️ Really interesting videos and a wonderful way to present mate! Hope you get much more attention, that you justly deserve, in the future!!
Still can't believe they let us walk around on the old satellite dish, although apparently they used to play cricket up there!
Keep up the good work :D

Honestly, your almost-too-professional-for-this-age style is so refreshing. The biggest compliment I can give you is that you remind me of Carl Sagan.
That was a phenomenal explanation of radio wave transmitters and receivers, I feel like I finally understand it thoroughly.
