This week, the story of the experiment changed considerably. In a thoroughly reported exposé on Medium, journalist Ben Blum finds compelling evidence that the guards in this experiment were not left to act on their own desires. Audio recording and interviews with those involved reveal the guards were coached into being mean or considered the experiment to be an “improv exercise.” Here is one of those recordings, via the Stanford archive. It’s pretty damning. You can hear David Jaffe, one of Zimbardo’s students who acted as the prison “warden,” chastising a guard for not being severe enough.

This subject just by itself would require a discussion of encyclopedic proportions:

https://blogs.scientificamerican.com/life-unbounded/the-erosion-of-reality/

We humans have arguably been eroding our own reality from the moment our hominin ancestors and cousins started communicating and storytelling. A good fireside tale may help maintain a verbal history, or articulate moral and social rules, helping bring cohesion to our families and groups. But it can, perhaps inevitably, mislead, distort, and manipulate.
In a way, we might be getting ahead of ourselves by anticipating the birth of true a.i. so soon. But nobody knows if, or when it will happen.... but I'm sure that once it happens, it will be kept an extremely closely guarded secret until other nations (governments) develop their own.

I see the reflection of a Martian staring back into that top camera.
One of the biggest challenges for the rover is the accumulation of dust on its solar panels. I've always wondered how big of a challenge it would be to include a small air compressor in the design, and have the robotic arm periodically clean the panels with a nozzle, using short blasts of air.

Rather, look to nature for solutions...

Probably because it wouldn't be very practical. How well would you expect an air compressor to work here on Earth at an altitude of 90,000 feet? That's the average pressure altitude on the surface of Mars.

Oh, I'm aware of the very low pressure of Mars' atmosphere. My thought was around some sort of very slow working pump mechanism. Something that would accumulate enough air during the course of several months, so that only a couple of yearly blasts would be performed for maintenance purposes.

Most people don't know how big and magnificent Tenochtitlán was before the Spaniards arrived. It was bigger and better organized than most European cities. This is a short video (1:30) giving a few impressive facts about that metropolis:


Most of what is known today about Tenochtitlán comes from a book written by one of Cortés' soldiers, Don Bernal Díaz del Castillo.

Cocoa, FL (WFTS) -- On Friday, the State Attorney's Office announced that the four juveniles and one adult who laughed and recorded a Florida man's drowning death last year, will not face any criminal charges.

Jamel Dunn, 31, drowned in a retention pond in Cocoa, Florida, on July 12, 2017. Cocoa police say they later discovered that the group, ages 14 to 18, recorded Dunn's drowning on video.

In the video, the teens can be heard laughing at Dunn, saying that they weren't going to help him. One of them even appeared to laugh and say, "He just died!"

According to the State Attorney's Office, there is no law in Florida that requires people to give or call for help when someone's in distress.

Sick and sad.
