I love how educational this is, and the animations help so much it's unreal. Thank you!

The animation is really well done and super helpful 💯

It's interesting that Geiger counters are sort of the inverse of smoke detectors. With smoke detectors, you have radiation and look for a gas, while with Geiger counters, you have a gas and look for radiation.

As an engineering student who took up engineering for the love of physics and mathematics (partly inspired by great content on KZread, this channel included), I really appreciate you trying to deep dive into stuff no one bothers to know! A humble smoke detector has so much going on behind the scenes. Keep inspiring new people :)

what engineering did you course? these videos really interest me, and your interest makes me curious

I greatly enjoyed the humorous bits: “The battery, which is always dead”, “When burnt pop corn…”, “…indicating that you are bad at cooking”. Hahaha.

I can't express enough how much i am pleased with this video. And i love how you branched in a clever way to explain other relevant topics besides the mechanism of smoke detector and the incorporation of this mind blowing information about the sizes of atoms and the power they possess it's just amazing. The animation also is brilliant. I will always follow this channel and i hope you always upload videos like this without skipping any bits of information, the more dense the better :)

I can't get enough of your videos! They are the best! The time spent on animation is amazing! Keep up the great work guys! You have many fans!

I love this! it's not too simplified and not too much detail, it's perfect!

I cannot express how valuable this video is. I'm 64 and very curious, this video answered many of my question about atoms and some I never new to ask. Even your (add) was related to your video. The animation showing the various sizes of atoms overlaid on the periodic table was brilliant.

Just amazing work, simple to understand explanation, wonderfully made animations , Thank you to entire team for bringing such an amazing videos to us. 🌹👍

Unbelievable quality video. All your videos are so incredibly educational, I love watching your channel for hours on end. I often find myself revisiting your videos just to try and wrap my brain around the concepts you explain.

I was once called to assist with a fire detection system used in a diesel engine generator room. The 'authorities' wanted to test the system, so they set fire to a large pan filled with diesel fuel. The whole room was filled with smoke, but no alarms sounded. At this stage I entered the scene - I started the fan and got the 'diesel smoke' out. Then I got a cigarette from one of the engineers - lit it - and blew smoke into the fire detectors - all worked fine - the alarm sounded every time. Why you may ask. Smoke from burning fuel is (very) dark/black - and black does not reflect light - the cigarette smoke is 'white' - which reflects lights. Wisdom: look at what kind of smoke a fire will generate - the select the type of detector.

Well rare to see, I believe industrial fire prevention systems should use multiple detection methods just for this purpose.

So much information beyond the simple explanation. Love how in-depth you go. Also, how long did it take for someone to make this? So much knowledge needed to make something so "simple".

You are the one defining Education through Animations. Your animations are the most realistic and detailed. I am so glad that you do what you do.

This is very well put together. Amazing explanation & animation in demonstration. Thank for putting this together to share. Your content is top notch.

I love this video, the visual explanation is amazing the detail that your team must go through to gather as this information then sort it in a way so that most people can understand and to then make an animation for that then to synchronize everything is incredible truly making the world a better place. I also love the jokes that were put in and side mention of how it’s marketed effectively as it is both funny and still educational

Your content is amazing! One of the best parts of existing now is our unfathomable access to knowledge, and you work so hard to share such high quality educational information, it's an honor to learn from you. Thanks for all your channel does, it makes my life much better.

That was a very excellent demonstration & explanation of the smoke detectors not only at the hardware level, but it was also interesting at fundamental level, I totally appreciate your work and efforts to create this video.

Recently discovered your channel and am blown away by the way you explain complex topics with quality and clarity.

@@MattyEngland not only KZread, but online content in general, whether it's typed or videoed. Schooling as a whole is outdated. We need to recognize that schooling is only required to become literate. Once a student is literate to a sufficient degree, they can learn without a local-area teacher, instead they can learn by reading the material (textbook) of an internationally acclaimed teacher, or read and watch online material (usually free). The era of universities is hopefully coming to an end

Thanks, I’m an x radiation worker (meaning I’m retired not dead) and always look for incorrect information in such vids. Yours was spot on and well worth refreshing smoke detectors. I think your conclusion re danger of alpha v gamma needs more explanation ie that tiny alpha emitter would destroy your inside pretty quick, BUT a dose of a few hundred micro sieverts for several minutes would most likely cause no issue, tho NOT recommended either. Thanks again

It took me until almost the end of the video to realize you were showing atoms with electron clouds as opposed to orbits. I'm glad we're starting to move away from teaching that model and appreciate you contributing to that movement.

In the same way people become accustomed to smells in their homes, people become accustomed to noise in their home as well. Eventually, your brain just tells you it's normal, and you tune it out. They're not necessarily dumb. They've just let it beep so long they don't even hear it anymore, and then they forget completely to change the battery.

learning has never been so beautiful. Thanks!

7:25 "...Or you're bad at cooking" that made me laugh my ass off

"Or u r bad at cooking" damn bro went straight to the point

The genius part of this "ionizing detector" is that it occludes the fact that it is in-fact the radiation everyone is "afraid" of when you say radioactive... but then there is ionizing radiation and non-ionizing radiation! Out if which the first one is in-fact the harmful one :D

although i couldn't understand but i liked your field of study

I.LOVE.THIS.CHANNEL. THANK YOU SO MUCH!!!

According to my using experience on both of them, the radiation type smoke detector lasts very long, over 20 years without trouble, but it only able to detect smoke ! The laser beam type detector triggers the alarm even with steam or oil vapour during cooking that I do not like if it is installed in kitchen area close to stove. It is much more expensive as compare to the simple radiation type. Not like the radiation type runs with 9V, it requires both batteries and AC power that is not so simple to install and runs it. It starts has trouble after two years like sounding alarm by itself without detecting any smoke or any vapours. I repaired them by cleaning the laser chamber where I saw very few and fine dust accumulate inside, but some still fault alarm after cleaning.

Have you covered the L.D.50 topic? I've done pest control for 16 years and was stunned when I first found out everything l.d.50 related.

This is incredible... Hat's off

Very well explained sir
