+ - In 1972, Scientists Discovered a 2 Billion-Year-Old Nuclear Reactor in W Africa

Submitted by KentuckyFC
KentuckyFC (1144503) writes "In June 1972, nuclear scientists at the Pierrelatte uranium enrichment plant in south-east France noticed a strange deficit in the amount of uranium-235 they were processing. That’s a serious problem in a uranium enrichment plant where every gram of fissionable material has to be carefully accounted for. The ensuing investigation found that the anomaly originated in the ore from the Oklo uranium mine in Gabon, which contained only 0.600% uranium-235 compared to 0.7202% for all other ore on the planet. It turned out that this ore was depleted because it had gone critical some 2 billion years earlier, creating a self-sustaining nuclear reaction that lasted for 300,000 years and using up the missing uranium-235 in the process. Since then, scientists have studied this natural reactor to better understand how buried nuclear waste spreads through the environment and also to discover whether the laws of physics that govern nuclear reactions may have changed in the 1.5 billion years since the reactor switched off. Now a review of the science that has come out of Oklo shows how important this work has become but also reveals that there is limited potential to gather more data. After an initial flurry of interest in Oklo, mining continued and the natural reactors--surely among the most extraordinary natural phenomena on the planet-- have all been mined out."

'Commercial software' does not automatically mean 'closed software': ask Red Hat.

Yep. At first a few rogue scientist find something new. Then that 'something new' gets peer reviewed, discussed about, put through scientific screening, whatever. After that a few rogue scientists do NOT think the scientifically model is correct enough. (or the other way around)

We now have a whopping 97% of scientists thinking the models of global warming and the human factor therein is correct. So at some point 97% of scientists did not believe that global warming existed and / or was man made. The scientific advance is that we now have models that imply global warming is real and man-made. Is that what you wanted to say?

Who says that reincarnation processes (if they exist) are only taking place in a forward direction in time? Why not backwards? Or in the same time frame?

Come to think of it: maybe there is only one soul/entity/whatever that reincarnates in every living being throughout the times. Reminds me of Mehir Baba, but with continuous time travel added and everybody is 'god', but not everybody realizes it.

But also keep in mind that the dutch legal system is extremely wonky, ruled by judges who are completely out of touch with reality.

Because right now, this judge has declared that taking fuel from his car is not theft.

No, the judge has said no such thing. In fact, I wholeheartedly believe this same judge would declare the unauthorized taking of fuel from a car a criminal offense. The judge said that there is no criminal law against simply using someone else's network. And he is right: there is no such law.

+ - How to explain relativity in few words?

Submitted by dvdme
dvdme (1458155) writes "Recently I was asked to explain what was Einstein's theory of relativity in few and simply words to someone who doesn't knowledge in physics.
I'm not an expert myselft but I thought a little but about it and said that relativity explains how everything moves, in few words, the mechanics of the universe. Furthermore I also explain why it's called "theory of relativity", because it states the every movement is relative to the observer. I used the example of an observer inside a car vs. an observer outside a car.
I also explained how relativity describes gravity as a space-time bend by mass with the classical exemple of a heavy ball bending an elastic sheet, thus, "attracting" smaller balls.
I gave some examples of the consequences such as time dilation but in the end I got the impression that I didn't was very clear.
So, the question stood in my head, how to you explain what is the theory of relativity to someone without any physics background?"
