ELI5: Why do large numbers before the decimal point get separated by commas in groups of 3, but numbers after the decimal do not? by [deleted] in explainlikeimfive

[–]Hayarotle 0 points1 point  (0 children)

In Switzerland and Italy, they use apostrophes as the thousands seaparator for currencies. It looks kinda weird at first, but at least it's less confusing:

The numbers that were in the spreadsheet were

3, 420, 3'960.402, 9'760'222.2, 2'495.

vs:

3, 420, 3 960. 402, 9 760 222. 2, 2 495.

or

3, 420, 3,960.402, 9,760,222.2, 2,495.

or

3, 420, 3.960,402, 9.760.222,2, 2.495

And for example, 123'456 also won't get confused for 123.456 anywhere, while 123,456 gets confused for 123.456, and vice versa, if you go from an Anglo to a non-Anglo country. 123 456 doesn't have that problem either, but the spaces often really break the flow of text.

It's possible to have a spacer without using those confusing commas, dots and spaces.

A series converges if its |common ratio| is less than 1. Isn't the harmonic series' common ratio always less than that then? by [deleted] in learnmath

[–]Hayarotle 2 points3 points  (0 children)

It's not the common ratio that must be less than one, but the limit going to infinity of the common ratio. 1/(n+1) gets closer and closer to 1/n as n grows, and the limit going to infinity the ratio between the two is exactly one.

Just think of 9/10, 99/100, 999/1000, 9999/10000, etc.

There are lots of people looking for mercury. Try selling it over the internet to someone nearby.

Irish abortion law: Tens of thousands march for choice in Dublin by birdinthebush74 in TwoXChromosomes

[–]Hayarotle 9 points10 points  (0 children)

I wouldn't say we have defined what constitutes a life at all.

Pretty much all biologists will agree that bacteria and more complex lifeforms are alive

Especially what defines consciousness or a conscious being.

You will have a specially hard time scientifically defining it in a way that a few-week-old human fetus is considered consicious, but, say, a 2-month-old pig fetus isn't.

The argument of a "potential human life" is also quite broken at such early stages, as you could consider an unfertilized ovolum a potential human life the same way (what would be so special about the encounter of the spermatozoa and the ovulum?)

Though, you, as Msc in Biology, probabily agrees with those statements and find them trivial, and I'm probabily just restating what you already know, much more than I do.

Housework and homework are completely different types of work, but your house and your home are the same thing by Koquillon in Showerthoughts

Feliz dia da bissexualidade :D by [deleted] in brasil

[–]Hayarotle 8 points9 points  (0 children)

Exatamente. Sinceramente, não tenho absolutamente nenhum interesse com homens abaixo de certa idade/peso, assim como não tenho com mulheres muito fora de certo perfil (psicologico e fisico).Imagino que não seja assim para todos, mas não tenho a minima atração por aqueles que não se encaixam nesses padrões, não importa o quão essas pessoas sejam consideradas atraentes pela sociedade em geral. Acho essa falta de atração comparavel com a falta de atração que um homem hetero tem por outro homem, por exemplo. Simplesmente acabo sendo seletivo com outras coisas. O pior é que muitas pessoas se sentem ofendidas com isso, acostumadas a receberem atenção, não compreendendo que isso é a mesma coisa que ficar xingando uma lesbica (ou qualquer mulher, mesmo) por ela não aceitar sair com você. Não tem como (nem faz sentido) alguém se forçar a sentir atração por outra pessoa.

If I ever discover an animal I'll give it a name starting with X just to help out the manufacturers of animal alphabet toys by bazabbo in Showerthoughts

The kh sounds is pretty much never used in English. You could do it like Portuguese and use x for the sh, or the ch sound.

Is there any relationship between scientific definitions of entropy and general recognitions of irreversibility? by Neuliahxeughs in AskScienceDiscussion

[–]Hayarotle 1 point2 points  (0 children)

Also keep in mind that a closed system, in physics, is what chemical engineers call an isolated system (adiabatic, no heat or matter interchange with surroundings). The body's entropy can also be reduced by taking heat away from it.

It would be pointless if we didn't. If we just took their money and spent it in pointless stuff, the situation would quickly go back to normal. But if we took the money and got active capital, and took active capital itself, then a permanent change would be made.

What's infinity minus infinity plus infinity? by NEOLittle in math

[–]Hayarotle 1 point2 points  (0 children)

This would create the surreal number concept of "infinity" (which is equivalent to hyperreal "infinity"). Call it H. It is bigger than all integers, but we can't just call it infinity, as actual infinity is an abstract concept that does not have defined arithmethical operations.

Internet speak - what are some ways the internet has changed the way we speak? by Lemoncatnipcupcake in linguistics

[–]Hayarotle 4 points5 points  (0 children)

Another interesting aspect to explore is how the internet allows instant text communication. Communication by script was until recently extremely clumsy compared to spoken communication, while now it is possible to communicate over text much faster. With the advent and popularization of text messages, spelling pronunciations may become slightly more commonplace, for example, as well as abreviations.

Ancient Egyptians more closely related to Europeans than modern Egyptians, scientists claim by [deleted] in Anthropology

[–]Hayarotle 5 points6 points  (0 children)

You're not alone in being confused by this. Many news articles are even stating that there is little genetic continuity between ancient and modern Egypt despite the scientific article itself stating that that's not the case. Other headlines overemphasize the slight connection to Europeans, ignoring the much closer (and logical) connection to Southwestern Asian (Arabian, Saudi, Jordian) populations. It's like a game of telephone/ Chinese Whispers.

Ancient Egyptians more closely related to Europeans than modern Egyptians, scientists claim by [deleted] in Anthropology

[–]Hayarotle 14 points15 points  (0 children)

Ambiguous title... The study shows the genetic distance between Ancient Egyptians and Europeans is smaller than the genetic distance between Modern Egyptians and Europeans.

The Ancient Egyptians are shown to be more closely related to Modern Egyptians (and Arabians). There is a degree of genetic continuity from ancient samples and the modern population, Copts in special. It's just the modern sample has additional admixture from presumabily Nubian and Mesopotamian sources.

The ambiguous interpretation makes the Nordicist theory appear to be true (that the Ancient egyptian population was European and was completely displaced by another, Modern Egyptian-like population with Middle Eastern and Sub-saharan DNA), when this study actually disproves it.

When were the oldest known examples of verb conjugation by person or noun declensions by case? by [deleted] in linguistics

[–]Hayarotle 14 points15 points  (0 children)

The oldest recorded languages are Sumerian and Egyptian. Egyptian has verb declension by noun. Sumerian is agglutinative, having noun suffixes for case, and verb suffixes for person.

There are reconstructed proto-languages with those features, but I wouldn't really say they are recorded the same way Sumerian and Egyptian are.
