I LOVE how he incrementally explains each concept

[@jgizzy]

Why is it that almost all older educational videos are MILES better at explaining concepts and technology to people? I feel like our culture is losing their way in the art of explaining things and education in general, these videos are so simple and know exactly which words to use and demonstration displays to show. Thanks for posting this, after 27 years I now know how a thermostat works.

[@Blacklight8001]

true dat XD

[@thebeststooge]

Getting worse at a global scale too. Now they are pushing Political Correctness in History, Science, and even Math. I am amazed at just how far we are falling.

[@levimust4479]

I don't see what political correctness has to do with it. There is an intentional dumbing down of the population (e.g. hollowing out of public education) so that you can piss on their shoes and tell them it is raining.

[@VeganCheeseburger]

Could be survivorship bias. Probably plenty of crappy explanations background then too that simply didn't get copied and preserved

[@marcusaugusmarcellus8737]

I read "thermostat" on my Heater, here to find out what it is, now i know.

[@joelhonsberger1752]

I remember this show "Mr. Wizard's World" like it was yesterday. It aired not only on Nick(Nickelodeon) but also in Canada on Global TV in the 80's and 90's.

[@Shawnsanchez77]

Very cool video. I came looking for digital thermostat operations, but glad I found this little piece of gold.

[@vibhorarora1817]

believe me. i know that not many people watch such videos but these are reallllllly helpful.
thanx a lot.
and your way of explanation by showing is very good.

[@khellil2]

Yes, yes, we believe you.

[@kalaiselvan6907]

True

[@britebay]

Wow I love plain and simple explanation of thermostat working.

[@kaeez]

What a legend. You'll be missed Mr. Wizard.

[@chromaticturtle8657]

I'm almost 30 years old and was just laying down and thought "how do thermostats work" I was not disappointed

[@Broadbased]

Same here, haha. It's curiosity that drives us forward, so let's indulge in these random thoughts!

[@yojo619]

Watching it in 2022…Old education videos are so much better and clearer explaining things….People need to watch more of these

[@Phymacss]

I do agree!

[@levimust4479]

Older thermostats (like the ones in my home) have a mercury switch, which I guess have been discontinued to avoid mercury pollution. But were they more accurate I wonder? They seem to control the temperature very accurately.

[@DethWshBkr]

No. The accuracy is not nearly as good as a modern thermostat.
The mercury is NOT the temperature sensor, but the conductive electrical material.
The bimetal is what senses the temperature, but over years of flex, the metals begin to separate. At that point, you will have wildly inaccurate readings.

[@levimust4479]

You can tell this was filmed in the late '80s rather than the early or mid 80s because you can actually see this kid's forehead.

I was born in 63. I really believe people today are not as well educated as the past. Newspapers are almost gone, TV is even more mindless and distractions are everywhere (ie cellphone, video games and even computers)

[@owengaul3226]

[@owengaul3226]

newspapers have been replaced with online articles and news it is much better now

do you know what Bi means in 2019 is a whole new question lol

[@meRyanP]

The same thing it has always meant, two. You're referring to bi-sexual, which means...you guessed it...both (two) sexual preferences.

The "bi-metal" just goes up but shouldn't it swing more than one
