I've really enjoyed this series, Professor Dave. Thank you for taking the time to make it. As a suggestion, since I suspect you will bundle this into a series like you do with so many other multi-part topics, I suggest you call this bundle "The Wisdom of Trees." A great quote to round out this series.
Dendrochronology was used to date the Cascadia earthquake that happened in 1700! Scientists studied the "ghost forests" of red cedar trees in Oregon and Washington. Using dendrochronology they determined that the last growth year before the earthquake/tsunami was 1699. Archaeological evidence shows that several coastal villages were flooded and abandoned in 1700. Oral traditions of the indigenous peoples that lived in the pacific northwest coastal regions indicated that there had been an earthquake and tsunami flooding. They didn't have an exact date but knew how many generations had passed. Japan had historical records of the tsunami that occurred. The waves occurred in Japan on January 27/28. Carbon dating done on sitka spruce suggested that the trees died between 1695 and 1720 (less precise than the dendrochronology but still the correct range!). So notice that the dendrochronology data, carbon dating, historical info, and archaeology all corroborated each other. I think that is just beautiful. Tell this example to your friends that don't believe in science!

Perhaps you should rename your channel "Professor Dave Explains Everything". You have broadened your scope of topics covered. A great channel gets greater. Bravo. Two thumbs up.
the best about this type of dating is that its so down to earth that you can always point to it in case the people your arguing with refuse to acknowledge methods like isotope dating for example. you know, just in case you need to convince someone that the earth is older than 6000 years.
Yes, indeed! Tell young earth creationists this example to help them understand that isotope dating has merit: Dendrochronology was used to date the Cascadia earthquake that happened in 1700.

Tell this example to your friends that don't believe in science! Admittedly dating something that happened in 1700 is not the same as dating something that happened millions of years ago, but the point of the example is that radiometric dating does have merit. Sadly, young earth creationists think that radiometric dating is no good, so I like to show them how multiple lines of evidence corroborate each other.

It's really therapeutic and just an all round nice feeling taking on a subject and re-igniting the education endorphin so to speak. Appreciate you taking time in making your teaching pleasurable and involved and if laugh therapy is required you have ample charlatan destruction vids(flatearthers...oh my!) Your a good alround bloke like my O level chemistry teacher (B) who also had badminton amongst his cool attributes(hope your well MrDudley).
Really professor dave, all your hard works will repay you, YOU HELPED ME A LOT IN MATHEMATICS !!!! TONS OF LOVE FROM INDIA ❤️❤️🙏🙏🙏, I will become your patreon in future
They don't believe in it. Or they believe that it is impossible for scientists to get anything close to accurate information from it. This allows them to disregard it as a whole and not worry about it. Actually, I'm talking more about carbon dating, but I'm pretty sure the same would apply to dendrochronology.
I have a chemistry question for you. SpaceX super chills the fuel and liquid oxygen for their rockets. Does this effect the exhaust temperature? If you burn "A" and "warm" liquid oxygen and get a combustion temp of 1500 deg C, if you super chill A and the liquid oxygen, will the combustion temp change? If it does not, there would seem to be more heat change, so where would that energy come from?
Hey Dave, what is your take on Nassim Haramein, as far as physics go? I heard his talk about ancient history and he is talking pseudo-science nonsense. Is it just as bad when it comes to physics?
One of the followers of FLAT EARTH society contacted me, and I gave him the info on getting a tour to the ANTARTICA. I also gave them the link to your discussion (response?) to the FLAT EARTHERS. I think our friends on that ALTERNATE EARTH, aka FLAT EARTH, have lost a member.
Interesting video Dave! Could you please make a response video to the flat earth video that according to them "Debunked" your video with the 10 things that they always say!? it will be funny to watch you destroy them again!
You can tell if a youtube flat earther is a true believer by asking him or her "Can I use dendrochronology on you to find out how old you are?" If they agree without hesitation then they are a proper believer.

Professor Dave, I was wondering if you could make a video on explaining how what intelligence is and how it’s debated in psychology.

I like your ambition but why hide that as a subcomment^^?
thank you
That was a great watch! i watched this all in one sitting. Great content!
Dave - please do some kind of awesome science/engineering compilation with Mark Rober.
Very informative, thank you
Your every video is cordial I really enjoyed it thanks prof.Dave
Great video
Quality sir.... quality
Thanks Prof Dave for your presentation
I know a guy who is a 2nd generation Dendrochronologist and I think that is the fckng coolest thing ever

Professor dave, you got to share with us your time management. How are you able to know so many stuff?
Really professor dave, all your hard works will repay you, YOU HELPED ME A LOT IN MATHEMATICS !!!! TONS OF LOVE FROM INDIA ❤️❤️🙏🙏🙏, I will become your patreon in future
I wonder how young-earth creationists cope with dendrochronology.
Probably with some random bible passage.

Can you take on Qanon the way you took on flatearthers? Thanks
Hey Professor Dave, I absolutely love your content I think you should talk about Geology and Paleontology as well! Either way I’ll be watching :))
Geology is being written as we speak!
Professor Dave Explains Huzzah! Can’t wait :D
Respect from kurnool Andhra Pradesh India sir
Ooo wow I thought dendrochronology is just for trees but they are also for very old wooden materials!
For a modern day tale of dendrochonology - see how it was used as a forensic tool to track down the movement of the Tirpitz during WWII.
The more I watch intro more I like it

could you do more videos on mycology? there isnt much it feels like on mycology on youtube especially about fossilized mushrooms
Yes sorry for the delay, the series will be expanded very soon!
@@ProfessorDaveExplains 👍👍👍 excited to see the videos on them
Can you confirm how they use dendrochronology in determining co2 ppm in ancient climate?

I'd enjoy to your flat earth vs round earth video if they say the earth is flat how thick is the earth in that case

Do you have a degree in every single branch of study Sir?
Nope, just chemistry. Many of my scripts are written by other people, such as this one.
Interesting: at minute 3.40; The 18,000 years ago earth with it's glacial and sea ice, resembles a turkey with a bikini dancing..no?
