I Differential Geometry with GNU/Linux

[diegogarcia]

TL;DR

Basic differential geometry is made easy with GNU/linux tools.

Differential geometry is a difficult subject that lacks "easy" pedagogical examples.

However, using GNU/Linux tools, as I attempt to demonstrate in my web page, differential geometry can be easily explored so as to attain a thorough understanding of its principles.

"A picture is worth a thousand words" is the old adage and it does indeed apply to differential geometry.

I plan on more pages in the near future.

My antivirus software blocks your page with the message:
"Your connection to this web page is not safe due to an expired security certificate."
Can you fix that?

That is cool. If you want to do more in the future you might consider an Insights article or a series of them where everything can be put together with enough of an explanation for users to get started.

Hello,

I am sorry but there is nothing to "fix." The site uses http and not https and therefore there is no certificate required.

Perhaps your antivirus software is a bit too overzealous. There is nothing nefarious about the site. It is pure information with no third-party connections. The only javascript is used to display typeset math equations.

Maybe you could configure or disable, temporarily, your antivirus software. I don't know what else to suggest.

Thanks for the positive response.

However, the web page attempts to portray the Maxima/wxMaxima computer algebra software which is already very well documented. The Geomview/StageTools graphics are also well documented and any effort on my part would only be a duplication.

I would be willing to answer any questions on my web site but another series of articles would seem unnecessary.

How about upgrading your site to https?

How about upgrading your site to https?

Would you care to make a donation? Now, I am just being facetious, but I am financing my web site using my own funds.

This is supposedly a mathematics forum and I do not want to pontificate on unrelated topics but I have considered going to https but have rejected the idea. My reasoning is as follows:

Google and the other major web players definitely have serious security concerns. However, that is *their* problem and it is not *my* problem. I have absolutely no security issues and, consequently, I do not approve of these conglomerates forcibly including me into their security "solutions."

In short, I have absolutely no need for https and if the dominant Google Chrome browser or any other browser chokes on my web site then I consider it to be a fault that is entirely independent of and beyond my control.

I thank you for your response but I am unable to assist you in accessing my site.

As far as I understand, by choosing http over https, you are letting your visitors to have their privacy violated in that a third party can know what your visitors have visited, which image they loaded/downloaded and any input they may typed on your website.

No sane visitor would like to display their private life. I, for sure, would not want that. It's like letting my door and windows wide open all day long with curious people parked right on my doorstep watching my every move. I am not an exhibitor, sorry, but nope man. No way I will disable https for a website. Heck we are in 2025, not 1995.

As I have already indicated, I posted my web page on this forum in the hope of getting some sort of mathematical critique from the supposed experts.

But to my great surprise, the majority of responses have been directed to the totally irrelevant issue of http vs https.

I would rather not even bother to respond but I feel that my hand has been forced.

Firstly, a huge portion of the World Wide Web is still delivered via http and this portion includes oodles of academic pages on various scientific and mathematical topics. By limiting ones choice to "https only" then one is excluding oneself from much valuable and enlightening information (I can only hope that my humble web page qualifies in this regard).

Secondly, I cannot understand how an http-only page will not be displayed in any current browser. Certainly I have not, nor any other visitors have not, had any problem in displaying my simple web page or any other http-only page. Granted, I come from the GNU/Linux universe where total control is possible and even mandatory, but I also have access to Microsoft browsers that do not refuse to render http-only pages.

As I indicated, I am greatly surprised, and thoroughly dismayed, at the completely irrelevant and even nonsenical responses to this post.

I like it and will probably play with it some. I'll ask if I have any questions. I appreciate your effort. I disagree with the decision not to use https, but that horse is already dead. My browser offers no objection to displaying the site (Firefox on Windows with two security plugins).
