What is circumcision really about? In Genesis 17 it is the mark of the covenant between God + the descendants of Abraham. What does God do for the [descandants of Abraham]? He promises a multitude of descendants + nations, the land of Canaan, + promises he will remain their God. In return the foreskin of all males is to be removed! Why? The circumcision rite of a Jewish boy is called the “berith,” or “bris”, Hebrew for “covenant”. It’s done on the 8th day. Why 8? On the 6th, God made Man, on the 7th he rested; this is to stress the importance of the covenant.
There are many possible signs of such a covenant - e.g. facial tattooing. Why was circumcision adopted? What God gives in exchange is fertility. Was there any belief that circumcision produces fertility? Does it? Might it produce a less sensitive glans penis, + - longer coitus? Even so, how does this have anything to do with fertility? And how could anyone have known about it?
[Note Muslims, also descendants of Abraham - via Ishmael - explicitly not a part of the Covenant: Gen. 17:20. On this pulling passage wars are to be fought?]
Note the date…
If you’re wondering about intelligent life outside of this galaxy, I highly recommend this book. It’s a thoughtful and entertaining read.
Georges started it all, but Edwin had the telescope…
Just it’s luck - the smallest planet in the Solar System and it’s getting even smaller!
Images captured by NASA’s MESSENGER spacecraft have provided an illustration of Mercury’s shrinking and wrinkling surface over the past 4 billion years.
While the behavior of Earth’s outermost shell can best be explained through plate tectonics and the shifting of our lithosphere, Mercury has but one solid shell for a crust. As the planet’s molten core has cooled since its formation billions of years ago, the planet itself has contracted causing Mercury’s rocky exterior to crack and shift to accommodate the smaller size, much like the wrinkles that form on the skin of an apple skin as it dries out and shrinks.
"We see the landscape literally crumpling up," said William McKinnon, a professor in the Department of Earth and Planetary Sciences at Washington University in St. Louis. "Massive slabs of rock are sliding over one another."
As for the change in size, the study found in the journal Nature Geoscience notes that Mercury has seemingly contracted in radius in some locations as far as 7 kilometers, making the modern-day radial measurement of the planet 2,440 kilometers.
Celebrate NASA’s MESSENGER spacecraft and these recent findings by writing to Congress to let them know you support doubling funding for NASA!
To repeat my comment from earlier today… “So glad I’m not Mercury…”

The folks at Zen Pencils have adapted this rare 1968 interview with Stanley Kubrick on the meaning of life in a lengthy comic.
Also see Zen Pencils’ comic adaptations of Charles Bukowski on the ideal conditions and myths of creativity and Bill Watterson’s advice, based on his spectacular commencement address on creative integrity.
I’ve never been female. But I have been black my whole life. I can perhaps offer some insight from that perspective. There are many similar social issues related to access to equal opportunity that we find in the black community, as well as the community of women in a white male dominate society…
When I look at — throughout my life — I’ve known that I wanted to do astrophysics since I was 9 years old…I got to see how the world around me reacted to my expressions of these ambitions. All I can say is, the fact that I wanted to be a scientist, an astrophysicist was hands down the path of most resistance through the forces of society.
Anytime I expressed this interest, teachers would say, ‘Oh, don’t you wanna be an athlete?’ I want to become someone that was outside of the paradigm of expectations of the people in power. Fortunately, my depth of interest of the universe was so deep and so fuel enriched that everyone of these curve balls that I was thrown, and fences built in front of me, and hills that I had to climb, I just reach for more fuel, and I just kept going.
Now, here I am, one of the most visible scientists in the land, and I wanna look behind me and say, ‘Where are the others who might have been this,’ and they’re not there! …I happened to survive and others did not simply because of forces of society that prevented it at every turn. At every turn.
…My life experience tells me that when you don’t find blacks, when you don’t find women in the sciences, I know that these forces are real, and I had to survive them in order to get where I am today.
So before we start talking about genetic differences, you gotta come up with a system where there’s equal opportunity, then we can have that conversation.
"What’s up with chicks and science?"
Are there genetic differences between men and women, explain why more men are in science.
‘Oh, don’t you wanna be an athlete?’ Hahaha, omg… like… no…
Neil explained all this beautifully.
