Rao Saheb Dinanath Atmaram Dalvi (1844 – 10 February 1897), was my great-great grandfather an Indian judge and mathematicianHe obtained his BA degree in 1865 from Elphinstone College in Bombay. He was then selected as senior scholar and obtained the MA degree from Elphinstone College in 1866. He obtained his LLB degree in 1868 and was a Senior Dakshina Fellow in 1868.In the 1860’s he systematically examined Newton's rule for finding the number of imaginary roots and in 1869 published his book titled "An Examination of Sir Isaac Newton's Rule for finding the Number of Imaginary Square Roots in an Equation" in which he provides mechanical and geometric theorems and gives a direct and complete proof and disproof of the equation.D.A Dalvi states that the chief aim of his own rule was to find out the limit beyond which imaginary roots cannot exceed. He goes on to prove that if imaginary roots exist at all, they cannot exceed a certain number and in this show the superiority of the “Dalvi Rule “so referred to in the Times of India 9. He states that however it must not be supposed that this affords us the means by which to ascertain the exact number of imaginary roots any given equation may have, nor whether even one imaginary root exists in an equation. Newton’s rule may hence fail to detect imaginary roots in an equation when they actually exist in an equation and the roots may fall short of the number but be all real. He however agreed that when imaginary roots of an equation are all equal Newton’s criterial fully applies and although Newtons law is true for some values of the literal co-efficient of the general terms in an equation, it is not universally true.
I suspect in this case it might be linked to having smaller images to load better. But not certain about that.
I forgot if I told you or not
I don't think you did but it's good to hear nonetheless.
I'm uploading the best pic I have of me (^_~)
Ahh, competitors! 😂 Are you looking in India (guessing by your name? You don't have to answer that if you don't want to.
Btw quick ping because you are a {scope} type of person, now scopes show up on OurBigBook.com indices e.g. at ourbigbook.com/go/user/pioyi/articles we see the full "Ion Selective Electrodes / Response of the Glass Electrode " rather than just the final title "Response of the Glass Electrode" as it used to be before. This way it makes it much easier to identify what the article is about when looking at such indices. I ended up missing the feature because some of my "best" articles like CIA 2010 covert communication websites use scope and it had started to annoy me. Related master ticket: github.com/ourbigbook/ourbigbook/issues/144 All best.
Yes. I don't think they are bots, just organized spammer groups, given that signup has captcha and they have just one post per account. From Kenya, Pakistan and Vietnam most likely. Not very different from bots though in a way.
I was having some fun at first, but after they did vote fraud and reached the most highly voted article on the site I decided to intervene by forbidding signup from VPN and adding manual moderation locking tools and blocking banning the fuck out of them. It took a while but it seems to have worked and it has stopped for a bit.

hi
You found my secret OurBigBook account.
As a prize, you get to choose one policy change for the USA.

What are insane headers?
I've also now renamed "insane" to "shorthand" everywhere e.g.: docs.ourbigbook.com/macro-shorthand-syntax Hopefully it will be less confusing for future users.
hahhahahah I would consider that if I had the courage to do that in front of my professors hahahahah
I understand that it would be helpful though.
Cool! I spent some time yesterday Wiki binging the main compounds and applications of fluorine. My favorite one is of course Uranium hexafluoride!
If you ever do an experiment that doesn't have a good YouTube video, make sure to strap a GoPro to your head and get it on camera 😊 ourbigbook.com/cirosantilli/videos-of-all-key-physics-experiments
Having articles be named in the singular seems like a better approach.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.

  4. Infinitely deep tables of contents:
