Green for a weekend.
My green action was gathering nature testimonies of spring's early beginnings along a hiking trail in the pleasant community of St. Jacobs near Waterloo. Stay tuned for details.
Confidence vs. Arrogance.
I put some thought into it. We could have 3 situations:
1. Confidence assumed as Arrogance
2. Arrogance assumed as Confidence.
3. Have both.
The only thing to do is to dispel the assumptions.
Assumptions could be a source of strength but also of weakness. As everything in life the harder you get it the more valuable it is. In consequence the assumptions that require some effort of imagination (like the Martians theory or the Think Different scenarios) are the most rewarding.
On the other hand no effort assumptions are most often the sources of weakness. For instance all discriminations (race, sex, religion, nationality, etc.) are based on “evident” assumptions that since the other one is different it means that he/she is inferior. They are so dangerous that sometimes could cause wars. The sad part is that some people never learn.
I have composed below a chain of assumptions for those that need convincing that assumptions have to be checked before jumping into conclusions:
I assume that
Your assumption about
Her/His assumption about
Our assumption about
Their assumption about

Are we Martians?
Recent observations on microbes make us to change what we know about life resiliency. Microbes are finally getting respect as Tarter stated. Extremophiles prove that there is life in the most hostile environments. Living microbes were found in high acidity lakes at the bottom of deep oceans, in rocks or in the cooling water of nuclear reactors.
Considering these it is not out of question that some microbes could live under Mars surface. Now if an asteroid hit Mars in the past it might be possible that a dislocated rock escaped Mars' weaker gravitation and was caught by the Earth. It is a hard to believe scenario of Earth's life being "imported" from Mars. This assumption needs to be proven false before concluding on the second genesis that happened on Mars.

Where are we coming from?

Just 7 beauties!
Wind turbines are not only strong and beautiful but also misterious and impressive. It took me some time last summer to "chase" them near Goderich. Finally I was rewarded with a nice near by video shot.
Wind energy demystified.

She is after them.
YOU and everything else, are made of stardust, this was Tarter's take home message suggested to the audience. I found though that her presentation had more than one interesting message to take home. Here there are few of them:
1. life is more resilient than we expect, proving that it can exist in some of the most hostile environments.
2. this creates the scary possibility that WE ARE the first extraterrestrials since it is possible that we all are Martians.
3. the galaxies are green recycling machines.
4. at last I hear someone saying that number 2 is very important, since finding the second planet with technological traces, besides ours will prove that some form of alien life is possible.
5. telescopes can dance :)
6. SETI job could be compared with the archeological search of the needle in the cosmic haystack of the future, since our future is "written" in the stars.
7. if we never search, the chance of success is zero.
More to come...

To all the women in our life.
Thinking different has always been difficult. It took some time for the society to realize that women have equal rights (in society, at work or at home) with men. If not for this important achievement (that some are taking it for granted) it is worth celebrating this day for what the women in our life bring special.
