Absolute garbage science.

How is the scientific test of the half life clock going you have just under 23000 years to go before you even have a chance to say "what we know is " .With just one assumption the whole method is invalid

+Archaeo Duck Thanks for your information ,I only know the basics of this science , still do you personally ever think to yourself no matter how many top scientists believe this to be right , they have not recorded the results over 23000 or 150 billion years so well educated it may be it is still a guess. We can only see the end not the beginning . Then data from this guess work is used as fact in other formulas , and on and on it goes, With respect 2000 years yes maybe but It is amazing how most of us believe in creatures and bangs from billions of years ago when nobody has observed and recorded every minute or day of those many years. An open ,not a genius mind can't help but see a lie about our history hiding in plain sight . Peace. .

No, we can measure the rate of decay before it gets to this random 23,000 years figure. It doesn't have to reach the half-life for us to know what the half-life is. But in any case, it is tested against other known dates. For example, historical dates, and tree-ring dates. As I point out in the second video, scientists constantly test everything.

Many many thank Duke I have a question: how can we know the original amount of carbon 14. For example, if I count now the amount of it, how can I know that it is half the original amount NOT one-eighth!!! Or quarter not one-third!! I need, first, to know the original amount to start with!! Isn't that right? Please enlighten me Duke.
Archaeo Duck (2 months ago)
You are correct. Originally, Willard Libby assumed that the amount of carbon 14 in the atmosphere had remained constant over time, so it would be the same today as it was 2000 years ago. On this assumption, if we found one quarter of the expected amount (by comparison with the stable carbon 12 and 13), we could say the sample had been through two half-lives. BUT it was later realised that the amount has fluctuated, which is why radiocarbon dates have to be calibrated. I explain this in the second video: https://www.youtube.com/watch?v=7UxlRctd1pM Hope it's useful!

_neutrons_ turn into _protons_ in beta decay, not the other way around. Aside from that, it is a very good explanation, thanks!

I'm going to share this video like crazy. Great explanation!

Bullshit cause half the shit we carbon date is underground so how does the suns rays effect it

I like science when science forgets what science is. But in all seriousness... this is the most informative. I have watched more than a few just tonight and this was the best one. I subbed and clicked the bell icon. Thank you.

Thank you!
you earned a sub! good job in futur work. question: how does the clock start for radioactive decay of atoms that are not part of a once living creature? Ex: volcanic rocks
best of luck, I can't help but end it with "duck" <3
Archaeo Duck (1 year ago)
Thank you! This kind of feedback means an awful lot to me - you students are the future of archaeology :-)
you simply rock! I'm a Tunisian student in archaeology and I believe your futur videos and the vulgarization they provide will help us recruit new people ;) keep it up duck <3
Archaeo Duck (1 year ago)
Good question! For isotopes found in igneous rocks and their products (e.g. sand), the 'clock' starts at the time of the rock's formation, by cooling from magma. The decay products of radiation are able to escape the rock while it is liquid, but cannot do so once it has cooled and solidified. Potassium-argon, and argon-argon dating are useful in archaeology when a fossil is preserved between two different layers of lava flows. That's how archaeologists were able to date the early human remains found at Olduvai Gorge, Tanzania.

brilliantly explained. Especially how the clock starts part. I always wanted to know that. But most videos never touch upon this. Subscribed!

Hi great video - I'd like to use this with my students. Can you tell me the original video source that doesn't have your logo covering some information and without some info being chopped off. Many thanks :)
Archaeo Duck (1 year ago)
Hi John, sorry about that, it is frustrating indeed. Unfortunately, there isn’t an original source that I can give. I have taken your comment into account in the second part, and tried to ensure that nothing is covered. Hope it’s useful anyway :-) Chloe

Hi! Could you make a video explaining how to go about getting a job in archaeology following graduation and maybe discuss some of the Pros/Cons of a career in archaeology? For instance, I've seen and heard a lot about how an archaeology career can be quite temperamental due the majority of archaeologists needing to jump from one temporary contract to another as permanent/long term positions are quite rare... Thanks :)
Ben Lee (1 year ago)
Archaeo Duck Thank You!!
Archaeo Duck (1 year ago)
Hi Ben, Thank you. This is a brilliant question and would be a really useful vlog. I'm going to start looking into the best way to make it. Watch this space! Chloe (ArchaeoDuck)

Hi! I'm about to start college soon and I want to be an archaeologist but I don't really know what I need to do to be an one. Could you explain what kind of schooling someone needs to be an archaeologist? I know I'll need to go to field school but that's all I know. Thanks for your help, Penelope PS I love your videos
Archaeo Duck (1 year ago)
Hello Penelope, great question! The thing I love about archaeology is that people come into it with a huge range of different skill sets. Some are generalists; others focus on scientific archaeology, or historical archaeology, and there are many other variants. As far as general archaeological skills go, you can expect to need a bit of maths, and some writing ability (e.g. to produce reports). Useful subjects to focus on prior to going into archaeology include history, geology, any of the core sciences, maths, classics, and geography. There are probably more that I haven't thought of. My 'A' levels included Music and English Literature - hardly the most obvious choices for a person who went on to study archaeological science! Of course, a lot depends on the course and what they offer. Some places focus heavily on a particular period, others on an aspect of archaeological science. It depends also on which country you're in, and what kind of archaeology you want to go into. In short, there are plenty of options. If you'd like to ask more specific questions, feel free to respond to this message. And good luck!
