I think I've found the source of my headache; my first name quoted in conjunction with Von Daniken lol
Living in Quebec can't help any :-)))
Still, in-between quiet revolutions, we manage. Especially when it's cold, we like to recharge our batteries and take it easy.

Shhh - please don't scare the fishies.

Hey Pierre.... since you are around ... i wanted to ask because i know you are a lot better in english than me......


when we talk about number of stars... number of planets... number of galaxies....

it seems to me english only know 1 word "billion" ... it is like they only have the words "million" and "billion"..
but since you are a french canadian as me....

Je me demandais comment est-ce possible que en anglais ils ne connaissent pas autre nombres ?
en français nous avons : million, trillion, quatrillon, quintrillon, hexatrillion... septatrillion... octatrillon... nonatrillon... decatrillon.... etc etc etc..
il n'y a pas de corespondance en anglais ?

ils savent pas compter aussi loin ??? LOL

million=1,000,000
trillion=1,000,000,000
quatrillon=1,000,000,000,000
quintrillon=1,000,000,000,000,000
hexatrillion=1,000,000,000,000,000,000
septatrillion=1,000,000,000,000,000,000,000
octatrillon=1,000,000,000,000,000,000,000,000
nonatrillon=1,000,000,000,000,000,000,000,000,000
decatrillon=1,000,000,000,000,000,000,000,000,000,000


oopps i forgot "milliard".... trilliards, quatrilliard... quintrilliard.... etc
je sais plus where they go in that list lol

Le même problème ici.
In English, magnitudes are referred to in a very different way than what we do in most European countries.
A milllion is the same but then it gets worse.
For example, an English Billion is for us a Milliard.
Which means that our Billion is 1000 times larger than an English Billion...

In England a Billion was at one time a million million, but we changed from the long scale to the international short scale so it's now 1000 million.

The long and short of it!

so when you say there are a billion of suns in just our galaxy....
how many it is ? 1,000,000,000 stars ? or 1,000,000,000,000 stars ? which system you take ?

and when you say there are probably a billion of galaxies.....
how many it is ? 1,000,000,000 galaxies ? or 1,000,000,000,000 galaxies ? idem

so there are how many stars in the universe ?
:P

How many planets there are on average per star? 4 ?
how many planets in the universe ?

so depending the system you use...
or we can get 4 exa planets or you get 4 yotta planets
thats a huge difference. how we know ?


how we know ?

each time a person writting the word "billion" in a post ... should i reply everytime asking which system they use ? short scale or long scale ?

Merci à toi, Michel; grâce à toi je peux entâmer avec bonheur ma nouvelle bouteille d'aspirines ^^

I find that Petaflops supercomputers are sexy, and Petaplanets very much less so. For the latter, I'd prefer 10E15 or 10^15 (no aspirins required lol)

But really, I declare forfeiture and call upon the powers of Wikipedia :

Long and short forms
Échelles longue et courte

As long as you remember that the expressions millions, billions and billions and trillions are trademarked by Carl Sagan (almost).

so depending the system you use... or we can get 4 exa planets or you get 4 yotta planets thats a huge difference. how we know ? how we know ? each time a person writting the word "billion" in a post ... should i reply everytime asking which system they use ? short scale or long scale ? LOL

Now if 10x10 equals a hundred, 100x100 equals a thousand and 1000x1000 equals a million then shouldn't 1000000x1000000 equal a billion?

Cheers.

Under the original 16th century long scale French definition of billion, it does. But later on, it got complicated :

According to the Oxford English Dictionary, the word billion was formed in the 16th century (from million and the prefix bi-, "two"), meaning the second power of a million (1,000,0002 = 1012). This long scale definition was similarly applied to trillion, quadrillion and so on. The words were originally French, and entered English around the end of the 17th century. Later, French arithmeticians changed the words' meanings, adopting the short scale definition whereby three zeros rather than six were added at each step, so a billion came to denote a thousand million (109), a trillion (1012), and so on. This new convention was adopted in the United States in the 19th century, but Britain retained the original long scale use. France, in turn, reverted to the long scale in 1948.[4]

In Britain, however, under the influence of American usage, the short scale came to be increasingly used. In 1974, Prime Minister Harold Wilson confirmed that the government would use the word billion only in its short scale meaning (one thousand million). In a written answer to Robin Maxwell-Hyslop MP, who asked whether official usage would conform to the traditional British meaning of a million million, Wilson stated: "No. The word 'billion' is now used internationally to mean 1,000 million and it would be confusing if British Ministers were to use it in any other sense. I accept that it could still be interpreted in this country as 1 million million and I shall ask my colleagues to ensure that, if they do use it, there should be no ambiguity as to its meaning."
(Wikipedia)
My opinion on all this ? For sanity's sake, politicians should be restricted to the word gazillions for anything beyond a million, and they would do well to keep an eye on those dangerous French turncoats.

Very informative, thanks - but surely you aren't invoquing this (speaking specifically about the red colored countries) "majority" of closed democracies shackled by the uninformed or self-serving choices made by their dogmatic politicians over the last centuries, in defense of the short form ? *cough* *gasp* *lol*

A big mystery remains: Greenland. We really should poll those of our fellow SETIzens originating from that grey area, because not taking a stand in the age of Big Data isn't much of an excuse (or is utterly admirable, depending on how beneficial the absence of collected data can be).

Guilty as charged :D But essentially, just keeping comm channels open (my pathetic attempt to turn back the topic to SETI & Radioastronomy issues) so that we can keep navigating from bloodless quiet revolution to bloodless quiet revolution toward a brighter and singing future for all good-willed and honest citizens, what else ? :)

LOL. Greenlandic is closely related to the Inuit languages in Canada such as Inuktitut.

But they also speak Danish since Greenland is part of Denmark.
I'm pretty sure they use the long scale as the Danes does but perhaps some other scale when speaking in Kalaallisut or West Greenlandic, that has been the official language of the Greenlandic autonomous territory since June 2009.

I like this: "Do your best, but remember and accept that you can’t fix arrogant ignorance." because it so fits in politics today.

Raw data, spectrograms (dynamic spectra), filterbanks, waterfall data... All about the data formats Breakthrough Listen and Berkeley SETI want to make openly available to the scientific community. Accessible and enlightening article, but can rapidly get technical as soon as you scratch the surface !

2019.02.02 - Open data by Steve Croft
Breakthrough Listen generates huge amounts of data, particularly from the two main radio telescopes where we're doing routine observations, Green Bank and Parkes (and we'll be generating even more once we begin routine observations with MeerKAT). Part of our mission is to make as much of that data as possible publicly accessible, and to that end we have a substantial amount of data already in the Breakthrough Listen Open Data Archive, with much more to come in the near future. (...) We're hopeful that releasing raw data in open format will encourage more collaboration between SETI researchers and experts in the tech and RF industries, and that we'll be able to work together on algorithms to identify a wide range of signals both in our data, and in similar data from other sources, in search of that elusive signal from a technological civilization beyond Earth. http://seti.berkeley.edu:8000/open-data/ http://breakthroughinitiatives.org/opendatasearch
