Egyptian 'nfr' was more like a reference point. They had a concept for the ”base” or ”ground-level,” for their architectural plans. For ex. ”1 cubit above nfr”. And all the nos. would b made by combining multiples of the symbols, so they hd no use for 0 even as a placeholder
THREAD!
You very cleverly picked the facts according to your narrative. And distorted them to subtly establish your false narrative that India is not the originator of Zero. So let me tell you the remaining unlooked facts that you "forgot" and show you the full history of zero.

Once upon a time in the land of Mesopotamia, there lived a people who engaged in commerce, had a system of weights and measures, paid in currency, and most importantly, kept written records of all of this in clay tablets. These were the Sumerians.

The Incas had the decimal system but so did the Harappan people in 3500 B.C.E.
Also, the Incas neither had the Idea of zero as an integer nor did they have a symbol for its representation.
Coming to the Babylonians, their placeholder was not a true zero bcoz it was not used alone, nor was it used at the end of a number. Thus nos. like 2 & 120 (2×60) looked same bcoz the larger nos. lacked a final sexagesimal placeholder. Only context could differentiate them.
And for Greeks, they had no symbol for zero (μηδέν) and did not use a digit placeholder for it. They seemed unsure about the status of zero as a number. They asked themselves, "How can nothing be something?"
Ptolemy, influenced by Hipparchus & Babylonians, ws using a symbol for zero(as shown in pic.) bt again the symbol he ws using ws used by two continuous mathematical functions, one within another, so it meant zero position (minutes of immersion at 1st & last contact), nt none
The Symbol used by Ptolemy changed over time. In the 2nd century was a very small circle with a long overbar. Later, the overbar shortened to only one diameter, similar to the modern o-macron (ō). The overbar was omitted in Byzantine manuscripts, leaving a bare ο (omicron).
This gradual change from an invented symbol to ο disproves the hypothesis that the Omicron was the initial of οὐδέν meaning "nothing". [Neugebauer, otto].
Also, the omicron was being used by the Greeks to represent 70.
Cheers 2 Mayans & Babylonians fr invnting wht is oftn calld as "Placeholders". Bt they were nthing more thn blank spaces or at times two wedge shapes. Wht they did ws solv a practical problem of distinguishing nos. like 89 and 809. They didn't thought of 0 as a concpt or num
No one even dared to think about concept of zero. Until a Rishi from India named Pingal gave the world the first recorded concept of Zero(Shunya). Which is later adopted by other civilisations. Around 250 A.D. India gives first recorded usage of Shunya in the Decimal system
And, then in mid 6th century, an INDIAN named Brahmagupt defined the first recorded rules of modern zero. Wherein Zero is an integer and is an average of -1 and +1.

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.
https://t.co/FBfXhUrH5d
Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.
...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.
Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.

Imagine for a moment the most obscurantist, jargon-filled, po-mo article the politically correct academy might produce. Pure SJW nonsense. Got it? Chances are you're imagining something like the infamous "Feminist Glaciology" article from a few years back.https://t.co/NRaWNREBvR pic.twitter.com/qtSFBYY80S

The article is, at heart, deeply weird, even essentialist. Here, for example, is the claim that proposing climate engineering is a "man" thing. Also a "man" thing: attempting to get distance from a topic, approaching it in a disinterested fashion.
Also a "man" thing—physical courage. (I guess, not quite: physical courage "co-constitutes" masculinist glaciology along with nationalism and colonialism.)
There's criticism of a New York Times article that talks about glaciology adventures, which makes a similar point.
At the heart of this chunk is the claim that glaciology excludes women because of a narrative of scientific objectivity and physical adventure. This is a strong claim! It's not enough to say, hey, sure, sounds good. Is it true?
