last week i went to the Natural History museum in London it's a very amazing place specially the part about human origins is really interesting. it's pretty amazing that the data they present is that chimps have 99,4% of DNA in common with humans. I mean i knew it was alot of DNA in common but didn't think was that much. 99,4% means that what's different is just 0,6% . I'm really courios also if anyone did any resarch about which genes are in this 0,6 % in common, and if yes what are etc.. there's a really interestinghe taxonomic classification, but talks also about behaviour. That's the book is sudgested in the video: Chimpanzee Politics: Power and Sex among Apes by Frans de Waal. There's an interstenting part about interview as well that can be view. in the beginning the video it is more about evolution:

• specialy the interactive demonstration/simulation about natural selection.
  
• social learning in primates, video. they focus a bit with the role of playing and how it is realate with learning. also the role of imitation in learning.
• evolution or modern human, video.
• human origins , video .
• how does evolution work , video.
• quiete surprised to see that a whale went into the thames in London. interview with the guy that rescued the whale.

the part i enjoed the mostis the photographic exposition.
according to me that's the most impressive picture.

how dangerous are electromagnatic radiation produced by cellphones?

here's an intersting experiment done by 2 russian journalist

basicly as you can see they put an egg betwen 2 phones and call each other for 65 minutes,after that period the egg was cocked.

on,one hand i did some reserch when i was at high school and i found out that after a couple of seconds that you are at the phone,the hear temparature starts to raise and after a little while the cortical membrane becomes less tight and some outside protein pass trough it and attacks/damage some neuros[ still looking for that reserch i did previously in highschool in order to find some more clear evidence about it]

on the other hand this other web site says:

A cell phone battery doesn't actually carry enough charge to heat an egg to the required temperature.

Skip the following figures if you don't care for physics:
A fairly average 3.6V mobile phone battery stores 730 mAh, which is 2,6 Wh (Watt hours) of electric energy. This is 1.7 kcal or enough to warm a 60g egg by 28 degrees Celsius (50 Fahrenheit). In other words, if all the energy used by the cell phone was converted into microwave energy (a lot of the electricity warms the silicon in the electronics and the display and thus just warms the handset) and all that energy were to radiate *only* at the egg and in no other direction, the egg would barely reach body temperature before the battery goes dead. In practice only a fraction of the energy would turn into microwave radiation that warms the egg. The numbers simply don't add up. Given the known specification of mobile phone batteries and the laws of physics it's doubtful if even dozends of mobile phones piled around it were capable of boiling an egg.

i still dunno..i do think that this fisics evidence is a focused on the cellphone battery and not on what is inportant: the electromagnetic feild and radiation which is active during a conversation..and there are ways of misuring it..

LINUX

anyone else using it?
personally I've divided my laptop in 2 parts and on one part i got mandriva linux free edition
and on the other windows xp.



for those who were wondering what am i talking about here's a link to linux on wikiepedia .
a great podcast that i've loved listen to and that helped me alot becoming a little bit more familiar with linux is:linux reality.
besides that there's still lot of stuff that i got to learn about it,like how to install programs :-S
but hey,here's the fun..if was easy would be boring after a while,no?!

ok,someone may be wondering why i'm soo faschinated by it..
well,several reasons:

first of all the philosophy that is behind open source programs,which was synthetically expressed as "Free software is a matter of liberty, not price. To understand the concept, you should think of free as in free speech,not as in free beer."

second the concrete realizations of most of linux distributions is something that i guess as never happened before: Think about it, we are talking about people creating theire own distribution and realise it on the www and anyonelse(with the appropriate knowledge ) from all over the world with an Internet connection can improve it and then realise it on the web and so on, and that imply that the "finale" distribution is fruit of people that other ways would have never meet them selves and that probably will never fisically do.


and most important of all, as once i heard in a survey from the economist web site"designing an engineering architecture implies defining a social structure".
think about what social structure create the open source model....inconstrast to the windows or apple one..

the acquatic theory
hmmm..what is it all about?!
if you are as curiouse as I was when i first heard of it, on the side you can find some more links about it.

btw,what i though could be intersting one of the evidence that seems to support the theory, one sentence I found on the wikipedia under "aquatic ape hipotesis":

"Kawamura in 1962 observed a troop of Japanese macaques developing bipedalism in water through cleaning sweet potatoes therein."


at the Laboratory of Physical Anthropology, Kyoto University they
found out that Japanese macaques consume more energy when using bipedalism.


comparison of acquatic hipotesis with terrestrial models...
