rząd logarytmiczny

Here, a Polish author uses "logarithmic order:"
The objective of the study was to determine the survivability of an Lactobacillus casei KNE-1 probiotic strain in the banana-milk drink (3:2), stored at temperature of 10 deg C for 32 days, depending on the added prebiotics: oligofructose (0.5 percent) and inulin with sucrose (totally 0.5 percent). It was found that while the drink fermented, the count bacteria in the drink increased by 3 logarithmic orders in the drink with oligofructose added, and by 7 logarithmic orders in the drink with inulin and sucrose added. And during storing, the cell count of the examined strain decreased by 4 logarithmic orders in the drink with oligofructose added, whereas the cell count of this strain decreased by 1 logarithmic order in the drink with the addition inulin

I would go with this answer, Tabor.

Looking at the usage of "rząd logarytmiczny" in
http://www.uwm.edu.pl/wnz/sitefiles/file/mikrobiologia/Żywno... (see Fig. 1), it appears to mean "units on the logarythmic scale." Here, the author plots the ratio of two logarithms. It is the change in this ratio that is called rząd logarytmiczny (units on the logarithmic scale).
However, in the reference provided by Colleague M. A. B., it does literally mean "orders of magnitude" in the sense of "powers of ten."

You make a very good point M. A. B. Let me give it another look-see.

But between 10^6 and 5.7*10^7 there aren't 3 orders of magnitude, but rather 2. Usually by an order of magnitude one means a logarithmic decade. And that's how it's understood also in some Biotech papers that I looked through where "rząd logarytmiczny" assumes log10 rather than ln as probably here. If you say "three orders of magnitude more than a million" you mean a ~billion rather than 57 millions :)

I dlatego przyjmijmy wersję fizyczną "order of magnitude". Winiarstwo to i tak głównie chemia a nie matematyka :)

In physics, at least, a scientist wants to convey an order of magnitude - a rough estimate of how something compares to something else. For example, if I say the temperature of the sun's corona is a million degrees, it does not matter whether this is in Celsius, Kelvin, or Fahrenheit. Here, the author wants to say that the numbers range roughly over three orders of magnitude.There is no pretense of exactitude. It is the qualitative feel that is conveyed. The actual numbers are given in the parentheses. In mathematics one would be shot for this; in physics and other sciences one would be praised for knowing the orders of magnitude of the phenomena being discussed.

W Polsce i tak dają za mało drożdży :) A tak na serio, fermentacja wcześniej by się zatrzymała - więc bez obaw.

Najwyżej komuś nie wyjdzie wino gdy zamiast 60 razy więcej da 1000 razy więcej drożdży :)

Wcale mnie to nie dziwi. Po prostu "twórca" nie rozróżnia logarytmów. W medycynie mamy co chwila takie problemy (np. ostatnio miało wyjść mnożenie [zgodnie z definicją] a komputerowi wyszło dzielenie). Ja bym dał wersję Franka. Nawet nie zauważą.

I entered my answer before reading your discussion, M. A. B.

Przypuszczam, że "1·106-5,7·107" to będą 1*10^6 i 5,7*10^7 (potęgi dziesiątki). Normalnie powiedziałbym "order of magnitude", ale to dotyczy potęg dziesiątki i 3 rzędy to byłyby 10^3. Tu mamy czynnik 57. Może zgrubnie chodzić o logarytm naturalny bo e^3 = 20 no ale jest to sporo mniej niż 57.
