These Oklahoma teachers are now permanently on strike

1 Comment and 2 Shares

Earlier this year, 30,000 teachers in Oklahoma walked out of their classrooms to protest teacher pay and education budget cuts. The walkout ended after nine days with the teachers’ goals partially met. Vice News talked to 18 Oklahoma teachers about why they’ve decided to quit teaching after this year, essentially making their walkouts permanent.

Eric Weingartner worked two side jobs in addition to his role as a full-time 4th grade teacher to make ends meet. Chemistry teacher Becky Smith’s monthly paycheck rose just $300 in sixteen years. Aimee Elmquist spent her own money to stock her biology classroom. Mary West did the same for high school art.

One of the biggest realizations I’ve had in the past few years is that while Americans talk a lot about the importance of children and education, those things actually are not that important to us. You can see it in how we approach our educational system and you can see it in how we our government uses the abuse of children to attempt to curb immigration with relatively little outcry. You can see it in our governance…the people we elect do what’s best for voters, not for future voters. The enthusiasm of hobbyists and desire of gun companies keep our children attending school in fear. Healthcare costs are soaring and coverage for children isn’t guaranteed. Our parental leave policies, maternity care, and all-around treatment of mothers & women in the workplace lags behind other so-called “developed” countries. Children are a priority for the US? Yeah, no.

Those grainy Moon photos from the 60s? The actual high-res images looked so much better.

13 Shares

In 1966 and 1967, NASA sent five spacecraft to orbit the Moon to take high-resolution photos to aid in finding a good landing spot for the Apollo missions. NASA released some photos to the public and they were extremely grainy and low resolution because they didn’t want the Soviet Union to know the capabilities of US spy satellites. Here’s a comparison to what the public saw at the time versus how the photos actually looked:

Old Moon New Moon

The Lunar Orbiters never returned to Earth with the imagery. Instead, the Orbiter developed the 70mm film (yes film) and then raster scanned the negatives with a 5 micron spot (200 lines/mm resolution) and beamed the data back to Earth using lossless analog compression, which was yet to actually be patented by anyone. Three ground stations on earth, one of which was in Madrid, another in Australia and the other in California recieved the signals and recorded them. The transmissions were recorded on to magnetic tape. The tapes needed Ampex FR-900 drives to read them, a refrigerator sized device that cost $300,000 to buy new in the 1960’s.

The high-res photos were only revealed in 2008, after a volunteer restoration effort undertaken in an abandoned McDonald’s nicknamed McMoon.

They were huge files, even by today’s standards. One of the later images can be as big as 2GB on a modern PC, with photos on top resolution DSLRs only being in the region of 10MB you can see how big these images are. One engineer said you could blow the images up to the size of a billboard without losing any quality. When the initial NASA engineers printed off these images, they had to hang them in a church because they were so big. The below images show some idea of the scale of these images. Each individual image when printed out was 1.58m by 0.4m.

You can view a collection of some of the images here.

How ants build bridges using very simple rules

1 Share

Check out these army ants building an ant bridge across a gap that suddenly widens:

Army ants have tiny brains and no one’s in charge. So how do they organize themselves into building bridges? They rely on their strength in numbers and simple rules.

To see how this unfolds, take the perspective of an ant on the march. When it comes to a gap in its path, it slows down. The rest of the colony, still barreling along at 12 centimeters per second, comes trampling over its back. At this point, two simple rules kick in.

The first tells the ant that when it feels other ants walking on its back, it should freeze. “As long as someone walks over you, you stay put,” Garnier said.

This same process repeats in the other ants: They step over the first ant, but — uh-oh — the gap is still there, so the next ant in line slows, gets trampled and freezes in place. In this way, the ants build a bridge long enough to span whatever gap is in front of them. The trailing ants in the colony then walk over it.

Things that are more heavily regulated in the US than buying a gun

1 Comment and 3 Shares

For McSweeney’s, Sarah Hutto offers up a list of things that are more heavily regulated in the United States than buying a gun.

Building a fucking shed in your own backyard
Disposing of fucking batteries
Cutting fucking hair for a living
Watching a fucking DVD
Importing foreign fucking cheese
Transporting a bottle of opened fucking wine home from a restaurant

Discussing the Las Vegas massacre yesterday on Fox Business, commentator Kennedy said:

If that psychopath had…driven a truck into that crowd and killed 100 people would we be talking about truck control?

Many quickly found the flaw in this “argument”, including @zeddrebel:

WE HAVE TRUCK CONTROL. Special licenses. Insurance. Regulations. Weigh stations. UNIONS. Bollards. GPS tracking…

(And btw, yes, it’s that Kennedy, the former MTV VJ and host of Alternative Nation.)
