Η διαφορά

Ποιά είναι η διαφορά μεταξύ του να κλέβεις και να δηλώνεις αθώος και του να είσαι αθώος και να δηλώνεις κλέφτης; Στην πρώτη περίπτωση φτιάχνεις ένα στρατό από φενταγίν και έχεις το κεφάλι σου ήσυχο ενώ στη δεύτερη μένεις μόνος με σπασμένο κεφάλι. Έτσι και η γυναίκα του Καίσαρα πρέπει να φαίνεται τίμια.
Γι' αυτό ήσυχα!..."στα κρεβάτια σας κορίτσια".

Aristarch is the famous astronomer who first argued about the heliocentric system, as well as a strong chess engine. Though it looked more probable that earth is the center of the universe, Aristarch considered a minor different possibility.




Computer chess is a modern hobby that attrackts thousands of people. A nise gui for chess is Arena.


Global Warming, ouch.

My research on climate begun few years ago. Then some intriguing results came out. Namely the low-dimensional Northern Hemisphere temperature variability due to seasonal solar variations caused by planets. Hopefully this research has intrigued the scientific comunity.

In an attempt to reach a broader audience around science, I posted in forums of Physorg.com - a well run blog on news on physics.

This is the original post from Apr 8 2006 in Physorg.com :

"This post has the form of the release of a climate model. The fact that I don't think that global warming exist doesn't mean that I agree with the environmental catastrophe taking place nowadays. This model predicts that the northern hemisphere temperatures are going to fall in years to come, though if it is correct and they don't fall, perhaps we have seriously damaged environment.

Few months ago the NTUA published my postgraduate thesis in the web:


There you can see that a simple two cosine model of 251 and 265.4 years periods, very well describes the Northern Hemisphere temperatures as reconstructed by Jones et al(1998).
The 251 years period is the seasonality of the Earth synods with Venus(wich is very canonical). The 265.4 years period is the mean period of the synods of Jupiter and Mercury with Earth when at the same time Earth is in synod with Venus too(these planets bring the greatest tidal forcing to the Sun and perhaps play a key role to Solar Activity that we get back here in Earth). The meaning is that there is a difference if the solar activity is greater if it happens when we have a summer or a winter at the Northern Hemisphere here in Earth.

The interesting is that this model very well describes the high temperatures of nowadays while at the same time it's 265.4 years cosine constituent reaches its maximum around 1950 AD wich really is the maximum of the 265.4 years cycle.
Moreover this model is a frequency beat of about 4500 years period and its' hights describe the last 10000 years Northern Hemisphere temperatures of Gisp2 in Greenland(their vest). Especially if you take into consideration the Precession of the Earth axis.
