Oklo: Natural Nuclear Reactors


Creating a nuclear reaction is not simple. In power plants, it involves splitting uranium atoms, and that process releases energy as heat and neutrons that go on to cause other atoms to split. This splitting process is called nuclear fission. In a power plant, sustaining the process of splitting atoms requires the involvement of many scientists and technicians.

It came as a great surprise to most, therefore, when, in 1972, French physicist Francis Perrin declared that nature had beaten humans to the punch by creating the world’s first nuclear reactors. Indeed, he argued, nature had a two-billion-year head start.1 Fifteen natural fission reactors have been found in three different ore deposits at the Oklo mine in Gabon, West Africa. These are collectively known as the Oklo Fossil Reactors.

List of Movies That Filmmakers Have Seen the Most

From Slate:

What movie have you seen the most? That’s the question Slate asked a collection of filmmakers and critics, knowing that what’s addictive is different than what’s deemed the best. The answers vary from Ghostbusters to Dr. Zhivago, from Citizen Kane to Election.

Star Wars for me although I only have them on VHS. I refused to buy the new editions that Lucas released on dvd.

An Open Letter To Rush Limbaugh


Very heartfelt:

To Our Fellow Viagraholic:

We feel your pain. We’ve been there, and we too have suffered the humiliation and shame of having our lives torn apart by Viagra abuse.

Rush, it doesn’t have to be this way. We at Viagraholics Anonymous are here to offer you hope.

We faced our addiction and are now on the path of recovery. If we can do it, so can you. We’re your brothers, and we want to help you spare yourself any more suffering due to this insidious addiction.

We know all the games. Hiding the pills. Lying to doctors. Getting multiple prescriptions, or prescriptions in someone else’s name. We tried all the same tricks, and like you, eventually most of us got caught.
