Carbon Dating DOESN'T work beyond 4500 years

Yup. 10-250. I don't recall the exact year, but maybe 72, maybe 73. Indeed, but it's a good story, and Donovan (IMHO) was capable of doing it.

So the legend is true!Did you meet Donovan in person? We only had his course recorded on tape at U of D. He was an inspiration. One night my roommate went down to campus just to view the Norway lecture again, "To get inspired," he said. Unforgettable guy!--Percy

Befoe the admins jump on us for being off topic I'd like to remind the young'uns that he'd have been using punch cards. And very likely he'd have had to rely on operators to actually run the cards through the reader and fetch the print-out. Letting the compiler cope with common spelling errors is a really good idea in that situation.

And in addition, the subject of carbon dating might become significant when determining how they buried TJ Watson. You folk be careful what you say about folk using puchcards. For some it was a clear sign of Evolution.

Aslan is not a Tame Lion

Yup, he did the lecturing, and was around before and after for discussion. Fascinating guy.There were three homework problems in the term:1. Given two numbers in specific registers, add them and put the result in a specified register.2. I forget.3. Write a compiler for a specified subset of PL/1 and compile a program supplied by the supervisor program.Each problem was pass/fail. The student's attempts ran under a supervisory program which logged the result in one of Donovan's private files. At the end of the term they looked at the file:.
.
.
Fred pass pass pass
Ethel pass fail pass
Tod pass pass maybe
.
.
.Given that it was a course in OS design, they had to give him an A.Perhaps apocryphal, but possible.

We once snuck a rotten banana into the middle of a big deck ... I don't know if the high-speed reader was ever quite the same.And musical line printers, and drum cards ...We're going to be quashed any moment now.

The problem is, the magnetic field is decaying around the earth. The earth is covered in a magnetic field, which is STEADILY losing its strength by 1/2 every 1400 years. There are no magnetic reversals--there are only areas of stronger and weaker magnetism...

Hey TC, nice to see you around again.

Hehe, either knows of it and ignores it or is talking from straight ignorance. Either way, this statement from the opening post might explain things:

Alright, as a Creation Scientist, this is a rather complex explanation, so sorry if I lose some of you...

Creation Scientist = filtered data set with a dash of ego.Anyway, on the previous page I have a graph that shows mirror images of magnetic measurements (not sure what the technical jargon is for these measurements) on either side of an ocean ridge. Things got pretty silent after that.I was trying to find a better graph of the data, but the graph I listed was the best I could find. Do you have better data handy? I have seen some pretty nifty graphs before, but wasn't able to find them.

Hey, thanks again for recommending that book to me last year. Read it all, still have it. I enjoyed the h3ll out of it.

--Most of the data I have is from my access to some of the AGU and GSA journals (eg. Geophysical Research Letters, Reviews of Geophysics, Journal of Geophysical Research (Solid Earth and Planets), Computational seismology and Geodynamics (largely useless for your inquiry), GSA Bulletin and GSA journal, Geology) as well as Geophysical monographs (AGU) and some copies from the AGU geodynamcis series.--You can also check out:Lowrie, William; 1997, Fundamentals of Geophysics, pp 295 - 303.Naar and Hey; 1989, Recent Pacific-Easter-Nazca Plate Motions, pp. 9 - 30. from Geophysical Monogrpah 57: Evolution of Mid Ocean Ridges. Editor; J. Sinton--I also have some geomagnetic data that I posted who knows how many years ago on evcforum:Data from:Cox, Allan; 1973, Plate Tectonics and Geomagnetic Reversals^check this book out, you'll love it if you are looking for plenty of geomagnetic data. It also anylizes the seafloor magnetic anomaly data against DRM (deposition [or detrital] remnant magnetism) paleomagnetic data which means the seafloor geomagnetic data wasn't just the result of tectonic activity on the seafloor or near a ridge (eg, like is implied by Brown's hydroplate theory).--There is a lot we can learn from the study of geomagnetic data, and not just the unequivocally clear inference that there has been geomagnetic reversals and also that seafloor spreading is real. Probably the most intriguing thing observed in the history of the geomagnetic field is the change in frequency of reversal rate over time, especially since the breakup of pangea as is seen in the data:--Why this pattern exists is interesting and may unlock many mysteries regarding what has influenced the behaviour of the geodynamo over time.--Here is the Geomagnetic polarity time scale for 0 - 160 Mya:--Of course you don't really get a full appreciation of geomagnetic anomalies until you've seen the actual intensity data plotted against 3D bathymetric data in full color. I don't have an image of that, but I'll be on the lookout if I have time.Cheers,

I only call them scientists as a curtesy. A new job title came to me the other night: "professional creationist". I think this is a more accurate portrayal of their job.

That is intriguing. A ca. 30 million year period with no reversals. Even though I am poorly trained in the Earth Sciences, I can still see the importance of this data. I smell a Nobel Prize for the first accurate theory.Anyway, thanks for the info. Between Mammuthus, Lithoid-Man, and you, it seems I have tapped into areas that other people have studied in great detail. Kind of fun to get people to talk about what they are really interested in. Well, now that we have solidified geomagnetic reversals, maybe the creationists can try and support the rest of booboo's argument.

that we might be in the early stages of a magnetic field reversal right now. Here is a link to a recent news piece on some of the latest studies.For me, the biggest question is, "Since this will be the first such event since civilization and recorded history, and in particular the first since the electronic age, what exactly will be the impacts?"

Very nice (the non-admin mode thinks), but very off-topic (the admin-mode thinks).I would love to see this in a new topic.I suggest the title "Plate Tectonics and Geomagnetic Reversals".Adminnemooseus

Adminnemooseus,
Well, I directly addressed a point brought up in booboo's initial post. I can see that discussing discussing the change in the frequency of geomagnetic reversals over time would be off topic, but I just thought I would inject that bit of information.Cheers,
