design of Geodesic dome

[Meparth singh rajput]

i am a researcher i want to conduct my research in geodesic dome with composite structure pls guide me where i start in this field 

[Ashok Mathur]

Dear Meparth,

To the extant I can, I will help you.

Please share with me your past background and what do you know about geodesic domes.

How do you want to utilize your research.

You can call me 0n 9823123050 and we can talk.

One of the good starting point is the book Geodesic Maths and how top use it by Hugh Kenner.

Its freely available on the internet.

Regards

Ashok

Thanks for responding. I am a phd scholar at NITTTR BHOPAL. My background is i done my master's in structural engineering, and now I am phd 1st year research scholar. I want to use geodesic geometry in my research work. I use composite structure application and solar energy integration in the panel of a geodesic dome. You suggested a book I can't find on the internet

Meparth: Have you contacted www.geoship.com? They make geodesic dome homes out of ceramics.

Meparth,

  Recently I posted this link since it has some useful information about dome calculations.

https://gill.readingroo.ms/ENTER/Science/Fuller,%20Buckminster%20Richard%201895-1983/Domes/Geodesic%20Domes.pdf

There is a vast wealth of information on geodesic domes available if you look.  Have you done a comprehensive search on the topics that interest you?   I ask, simply because you don't want to expend time/effort, nor your creativity/talents, on things that are already well known and documented.  The idea is to take what is already known and advance the invention/discovery of the discipline.

Keep up the good work.

Yes, I agree, that is good to know.  However, being professional skeptic, I will reserve judgement until we see what it "knows" play out into physical reality.  As Will Rogers famously said, it ain't what you don't know that makes trouble, it's what you know that ain't so.  

Let's hope it becomes another useful tool in the arsenal to improve the proliferation of domes where appropriate...like in record storms that generate wind speeds approaching 200mph, as Melissa hath wrought.

For fun, gpt says: give me a very skeptical answer to the question, is your knowledge of geodesic dome structuri

 thorough? 

ChatGPT said:

Probably not as thorough as a structural engineer’s or an architect who’s built one. My understanding covers the geometry, the load-distribution principles, Fuller’s design rationale, and the basic math of geodesic frequency divisions — but not every engineering nuance or material limitation in practice.

A skeptic would point out that:

• I don’t “know” in the embodied sense of someone who’s actually constructed or repaired a dome.

• My data rely on written and modeled information, not hands-on feedback from real-world stresses, humidity, or joint fatigue.

• Even experts disagree on the optimal hub connectors, insulation methods, or whether the theoretical efficiency translates into practical durability.

So: I can explain geodesic theory accurately, but claiming “thorough knowledge” in the lived, professional sense would be overstating it.

[Dx G]

Well, for fun I'd say that's a pretty good response. However, I'd have been more impressed by that answer if the question had not pointed the system in the "skeptical" direction.   One wonders if humility is built into the system, or just available if prompted accordingly.

(aka; TaffGoch, David Price)

[Dick Fischbeck]

Second prompt: Short answer: no—“thorough” would overstate it.

What I can do well:

• Explain the geometry (Class I/II icosahedral splits, frequency, chord factors, panelization).

• Generate strut/panel schedules and hubs for common V-frequencies.

• Talk through load paths, typical failure modes, insulation/condensation basics, and common materials.

Where I’m not thorough:

• Jurisdiction-specific codes, stamped structural calcs, snow/wind/ seismic design for your site.

• Build-method minutiae (e.g., precise hub systems, jig setups, on-site tolerances).

• Vendor-specific parts, pricing, and proprietary connectors.

• Advanced hybrids (tensegrity domes, large glazed geodesics, ETFE systems) beyond high-level guidance.

I’m solid for design math and planning, but I’m not a substitute for a structural engineer or an experienced dome builder. If you tell me your goal (e.g., size, site, budget), I can produce a strut/panel list and a practical build outline.

[Dick Fischbeck]

Anyway, I see potential here, especially for beginners.

[Dx G]

Yes, but not just beginners. Not a bad way for even the old timers to check their work, or hopefully, get ideas for the effort/project one had not even thought of.  It will be interesting to see how well AI can do more than just consolidate information, but rather, generate new things that are more than just restructured existing info; making a true invention. 

 In particular, another saying, to do the impossible you have to see the invisible.

This is a cautionary tale about Google AI. After seeing some weird "AI Overview" answers to various online searches, I thought I'd do a few tests. Here's one of them:

Google Search on Nov. 2, 2025:

"Is there any post on Google's Geodesic Help Group about similarities between Buckminster Fuller and Dutch Painter Rembrandt?" (The question was prompted in part by a discussion about credit given for the design work of T.C. Howard, a student of Bucky Fuller.)

Google AI Overview answer:

"There are no posts on the Google's "Geodesic Help" group about similarities between Buckminster Fuller and the Dutch painter Rembrandt.

The discussions in the group are primarily technical or historical, focusing on:

 -- The design, analysis, and construction of geodesic and tensegrity domes.
 -- Specific articles, reports, and books related to Buckminster Fuller's work.
 -- Fuller's life, his patents, and specific dome projects or homes.

There is no mention of Rembrandt in any of the search results from that specific Google Group."

Well, maybe Google AI has a short memory. Here's a post I wrote a little over a decade ago:

https://groups.google.com/g/geodesichelp/c/Bu4CWfFQRCk/m/YBtyToL0KAAJ

Looks like Google has trouble searching its own records.

Gerry,

 Thanks for posting that example.  As I posted earlier, Will Rogers: It's not what you don't know that makes trouble, it's what you know that ain't so.   

 So there are at least two types of errors.

1) Says its there when its not.

Some reports exist of AI offering actual references in the sci/tech, medical and legal areas that don't even exist. AI literally made them up.

2) Says its not there when it is.

Your example - AI missed it.

Well, I think of it this way. Sure, there are clowns out there that will use an adjustable wrench as a hammer, since it what they happen to have in their hand.  So AI is tool.  It provides some excellent capabilities, but like any tool, we must consider its limitations.   Serious problems can arise when people ignore those limitations and blindly accept AI output as fact, and then act on it, despite the errors (#1 an #2 above).  Humans are fallible, and as the creators of AI, so is AI.   The USA dropped the second atomic bomb on Nagasaki because of a translation error prompted by a certain level of arrogance, and it may have very well been entirely unnecessary.  We didn't have AI back then or even the computers we have now, and screwed up just fine without them.  Some of you may remember the ol' saying from the early days of PCs - To err is human, to really foul up, you need a computer. 

So the real key is to learn what AI does well, and can gainfully be used to augment a human decision making process...but also considering those limitations in doing so.  Those limitations also include our own limitations, such as a failure to recognize where AI may have messed up.  Same thing with relying *totally* on GPS mapping to tell us where we are and where we are going...

Ok, end of rant for now, but just telling most reasonable people what they already know.

Hi Gerry- I asked about your question and got this. Interesting.

why did it take chatgpt three prompts to reach that reference?

ChatGPT said:

Short version: your first asks were too vague for a brittle archive. Google Groups search is quirky, and my first passes didn’t have enough exact hooks.

Why it took a few tries:

• Ambiguous target. “Geodesic Help Group + Rembrandt” isn’t a common pairing; keyword search missed it without a precise subject/URL.

• Google Groups indexing is fickle. Subjects with quotes/ampersands (“Rembrandt & Bucky: Who ‘painted’ what?”) often fail simple queries; punctuation and smart quotes break matches.

• Date-only isn’t unique. “Aug 31, 2015” helped, but Groups spans time zones and threads; without the subject or author, results are noisy.

• Archive quirks. Older posts may be partially indexed, renamed, or nested under different threads; snippet search can hide the exact match.

How to make it one-shot next time:

• Provide one of: the URL, the exact subject, author, or a distinctive 6–10 word quote.

• If you only remember a date, add the time zone and list name.

i am doing coding with chat gpt, i think this is a strong point in selling these LLM spagetties.　

i asked chat gpt if it learns from our discussions, or once we get to the best solution will it be reused/provided for others.　

it said the training period ended, learning process was stopped before going public (it gave a certain date it happened).　

and even our previous  own discussions are invisible to it. 　

(i opening new chats, and we going through same mistakes as before).

this must be against sabotaging the LLM into some delirium or what. 　

but i am sure they collect everything, and the next gen AI (LLM) training dataset will include these sessions.　

　

and the 3 or more round conclusions are to press people to subscribe. with free / accountless sessions i guess deliberetaly degraded results arrive.　

something like the AI is  bullshitting us (and teasing us).

Hi Dick, Dan & Lev,

Thanks for the replies. Interesting to see the advice Dick got about punctuation, time zones, unique quotes, etc.  The more precise the clues you give Chat GPT, in its desired format, the greater the chances of a strong hit. But if you provide precise clues, it means you probably already know the answer to your question. I expect AI services will improve dramatically and quickly as both users and AI get used to each other, a bit like the leaps and bounds in online language translation. (I do volunteer work in my community and this requires a reasonably good command of written French. Google Translate saves me a lot of time because I simply edit its prose to suit my purposes. It makes my written French look better than it really is!)

Cheers,
