I just finished Xenophon's 'A history of my times' or 'Hellenica' which continues from where Thucydidies 'History of the Peloponesian War' about the war between ancient Athens and Sparta, left off. I'm also re-reading Robert Grave's 'The Greek Myths' a 'retelling of the stories of the ancient Greek gods and heroes, embodying the conclusions of modern anthropology and archaeology'. This book is a consolidation of the majority of references to the topic from Homer, ancient Greece, Rome etc to the early 1950's. Both are pre 1970's translations that only get into the moral relativism between the different ancient Greek cultures of the time. I have also recently finished Peter Levi's translation of Pausanias 'Guide to Greece', an ancient tour guide of all the towns and temples written by a doctor circa 200 ad, which was one of the main sources for Robert Graves book and a key reference for modern Greek archaeologists.

Hi Hawnk, You can probably do it in MS Excel with 3 lookup tables or worksheets depending on the complexity. That way you can set up your data in consistent rows and columns on one worksheet for statistical analysis or copy and past to other applications for the analysis. The MS Excel help files have examples of lookup tables and worksheets.

Determinism, denial, and psychological projection
LaurieAG replied to Genecks's topic in General Philosophy
An increasingly polarized society can behave very much like a pendulum as manipulated public perceptions swing from one side to the other with increasing frequency. If you go with the flow and swap sides and perceptions (regardless of morality, ethics and principles) and say nothing you will probably be perceived as positive by your masters of either persuasion (regardless of your morality, ethics or principles) but if you have a static perception of morality and ethics and view both extremes in this light you are more likely to be perceived by your masters of either side as negative regardless of your absolute position in the moderate center. I suppose it's up to the individual whether they value morality, ethics and principles over the alternative. At least according to the latest definitions of rape, the people who struggle or resist have some recourse while those who consent would be considered willing participants if no duress was involved. Entanglement is an interesting concept as the masters of either side try to make the people complicit in any atrocities to lengthen their reign when the pendulum starts to swing the other way. Sometimes this works for a little while and sometimes it merely accelerates the rate of the swing. One thing is for certain, when 'See no evil, hear no evil, speak no evil' becomes the social norm, evil is in control and the pendulum naturally wants to swing the other way. -
Has Dark Matter Finally Been Found? Big News Coming Soon
LaurieAG replied to ACG52's topic in Science News
Even CERN don't claim they have definitively found it any more than their previous announcements. The bolded bit below reminds me more of when global economists agreed that two consecutive quarters of negative economic growth don't indicate a recession in 2001, just before the dot com bubble burst, rather than any new scientific discovery. http://home.web.cern.ch/about/updates/2013/03/new-results-indicate-new-particle-higgs-boson -
Here is a comparison for those who think they might be cane toads. I have only spotted 5 cane toad tadpoles in the pool all up compared with hundreds of Blue Tree frogs. The cane toad tadpoles are much larger, are not blue in color, move very sluggishly and keep near the top in the fresher water. That's a ratio of around 2-3 % cane toads to blue tree frogs.

Actually that's Beach Blue with google translate and it seems that the original 1790's taxonomy was correct for the wrong reasons. http://en.wikipedia.org/wiki/Animal_coloration

As the Australian Green Tree frog is incorrectly called Litoria caerulea (Bleach Blue), I called this one Litoria caeruleum (means the same) to distinguish it. The original could possibly be called Litoria aureum viridi (gold/green) and this one Litoria aureum cæruleum (gold/blue). If future offspring could return to gold/blue in fresh water the change would be reversible although the internal salt content change may only allow successful breeding with other blue frogs in salty water due to osmosis. http://www.projectnoah.org/spottings/18385220

I would never have believed that there was a salt water frog that looked much like a Green tree frog until I saw these little frogs in my pool the other day. I initially thought they might be cane toads until I had a closer look and noticed that they had smooth skin and spots of gold along their sides. While the pool pump hasn't been working for a couple of months (no chlorination) and we have had quite a bit of rain lately the pool is still very salty the juveniles like to sit about a metre down before they come out. Freycinet's Blue Frog was originally discovered by Louis de Freycinet during an expedition led by D’Entrecasteaux in 1791. The drawing here from the State Library of NSW, painted circa 1790's, looks very much like the juvenile frogs in my pool and the adults that also live near near my fathers saltwater pool. http://acms.sl.nsw.gov.au/item/itemDetailPaged.aspx?itemID=411901# The following link refers to a Green Tree frog that was pickled in alcohol that appeared blue as the green pigment was dissolved. These frogs have black/blue skin but are alive and kicking. http://www.aqob.com.au/details.php?p_id=464&search=lee&searchid=38&seo=Australia's_Mysterious_Blue_Frogs If you know anything about osmosis through semi permeable membranes you'd know that they must have quite a high concentration of salt internally to be able to survive in these conditions.

Sorry to disapoint you menageriemanor but King Island Blue is a cheese. The cows aren't blue that's the colour of the mold in the cheese. http://kingislanddairy.com.au/ http://en.wikipedia.org/wiki/Blue_cheese Save that one for April 1 LOL.

Don't be surprised which direction they come from imatfaal. The Russian meteorite came from east to west and 2012 DA14 was supposed to go from south to north. http://www.today.it/mondo/cuba-meteorite.html http://thewatchers.adorraeli.com/2013/02/16/in-last-2-days-fireballs-were-reported-all-over-the-world-sweden-netherlands-russia-japan-cuba/ http://thelatestworldwidemeteorreports.blogspot.com.au/http://thelatestworldwidemeteorreports.blogspot.com.au/ One came over where I live from west to east around the time 2012 DA14 was supposed to pass by. Report them if you do see any.

If you rotate the NASA/JPL plan image so that the arrow to the sun aligns with the end elevation images arrow to the sun the path of 2012 DA14 goes from the north and heads towards the south not vice a versa. I always thought that Australia was downunder i.e. the Southern Hemisphere.

Hi Spyman, 83% of radiologists failed to spot the gorilla in the x-ray too. http://www.cbsnews.com/8301-204_162-57568784/can-you-spot-the-gorilla-in-this-ct-scan-most-radiologists-couldnt/ Considering that 9.2k people watched the NASA video with 37K likes the percentage of people who failed to spot this error is at least 99.9999%. Not good.

In the movie The Dish the young Australian technician said he redid the calculations because NASA had done the Southern Hemisphere calculations from the perspective of the Northern Hemisphere. http://en.wikipedia.org/wiki/The_Dish_(movie) 10 minutes ago I saw, during our 5:00pm news, that NASA has asked an Australian amateur astronomer to track the asteroid because the Sliding Springs (Australia's largest) Observatory is out of action due to bush fires. The simulated path is shown in red and it looks very much like the calcs were done wrong again.
-
Hey blackhat Spyman, I never said that I thought it would hit the earth. How do you reconcile the simulation that comes in and then goes out with the diagram that shows it going around?
-
http://www.nasa.gov/topics/solarsystem/features/asteroidflyby.html The simulation of the flyby doesn't seem to be correct. The attached image is my plot(s) for the flyby path of 2012 DA14. I had to reverse the side elevation, at least it was symetric, scale it, and plot each against the other as the NASA/JPL images and the simulation were in opposition. BTW, pink is the color you get when you reverse a dark image. I don't think it will hit, there is a possibility it will become a satellite, NASA only said it would not hit the Earth or any other planet although they made no mention of the moon which usually helps to capture quasi moons. The last image is from the second reference from the wiki below which links to an Australian Bureau of Meteorology (BOM) PDF. http://en.wikipedia.org/wiki/Orbital_decay

How do we know the universe isn't a loop?
LaurieAG replied to SamBridge's topic in Astronomy and Cosmology
My avatar is a feedback loop image with 0.5m in air (between CRT and CCD) and 0.5m in vacu running at 25 fps. That's why I wonder why we don't try to make astronomical observations without (1) planetary rotation, (2) earths orbit around the sun and (3) the suns rotation around our galactic center to see what our universe really looks like without the spin. -

Introduction to Calculus: Differentiation
LaurieAG replied to Cap'n Refsmmat's topic in Mathematics Tutorials
Hi Cap'n Refsmmat, At high school we studied 2 years of calculus and here are some things that I found made differentiation/integration a bit easier to understand. In its simplest form differentiation is the application of n * x ^ (n - 1) to all elements of x in equations of the form of a * x^2 + b * x + c = 0. The roots of the basic form are - b +/- the square root of (b^2 - 4 * a * c)/2a: [math]x=\frac{-b \pm \sqrt{b^2 - 4 ac}}{2a}[/math] The first differential of this basic form is 2 * a * x + b = 0 and the integral of this first differential is the original basic form because integration is the exact opposite of differentiation (the application of x^(n+1) / n to all elements of x + add a constant (x^0, which may = 0)). The units of acceleration M / second^2, speed M / second and distance travelled M all have a pure integral/differential relationship (between M with respect to time) that gets right to the heart of Newtons calculus and his mechanics. These proofs from first principles are good examples of pure applied calculus. Finally, in the basic form the last differential always goes to 0 and the first integral is the same and also goes to 0, unless you use a modified calculus, so make sure you don't overshoot on the way down or the way up. -
It also cannot simultaneously be 0 and one and infinity. 0/0 could be regarded as one and not one if anything divided by itself = one, none or not none if anything divided by 0 = 0, or infinity or not infinity if anything divided by 0 = infinity.

The modulo operator can be used http://en.wikipedia.org/wiki/Modulo_operation a = Students n = Bottles per pack = (3 + 1) x = Total Bottles purchased a mod n = a - (n * INT(a/n)) = 0 if a is divisible by n or = the remainder if otherwise. But there are much easier ways to skin this cat. So x = INT(0.5 + (a/n)) * n is simpler if the INT(number) function rounds up if the decimal part is > 0.5. and x = ROUND(0.5 + (a/n), 0) * n can be used, ROUND(number, decimals), if INT() doesn't round up > 0.5. ROUND(0.5 + 27/4,0) * 4 = 7 * 4 = 28 ROUND(0.5 + 31/4,0) * 4 = 8 * 4 = 32
