No, it’s probably not caused by sexism.
Here’s a crazy idea: Let’s spend them on highways.
This seems sort of useful for space settlement.
What will we do if and when there are no more jobs?
Disruption is good. As noted, any question of a ceasefire before those tunnels are ll destroyed is out of the question.
I’m surprised that they didn’t have a network of seismometers. I’d think they would have told them what’s going on. And of course, as usual, the UN was probably complicit.

All we are saying, is give war a chance.
Well, “peace” certainly hasn’t worked very well.

For surviving missiles intended to kill me. The fact they didn’t kill me doesn’t mean they weren’t sent with the intention to murder. We have a defence system, shelters, evacuation procedures and governments who take care of us – I will not apologise for living and surviving thanks to being prepared because we have a culture that celebrates our lives and cherishes them instead of sending 10-year old children to be fighters and bombers. I will not apologise for having a business, a home, a family and friends here who want normal lives and to live in peace with our neighbors. I will not apologise for existing and I want nothing more than to co-exist quietly with neighbors who accept me here.
But this is not what Hamas wants.
Let me be very clear. Hamas is trying to kill ME. My family. My baby son. All of us here. That is their purpose. Get it through your heads – that is what is happening. And it’s VERY personal. For all of us here.
But it’s NOT FAIR. Who are you people to defend yourselves, anyway? It’s not their fault that they suck at killing you. Why can’t you just off yourselves like those Masada people?
A great piece on the general irrationality about them, and the history. I find most interesting (and new) the point that the main benefit of posting a speed limit was not to slow the fastest down, but to speed the slowest up. More people need to understand that it is not absolute speed that is dangerous, but relative speed. When I was young, in Michigan, before Nixon’s double-nickle stupidity, the freeway signs had both a maximum and a minimum: 70/45. That was back in the days when older cars weren’t as safe or reliable at higher speeds. Today, I’d make it more like 80/60.
I’m also glad that they (as I always do) pointed out what a problem a lack of lane discipline is. If they’d give tickets for hogging the left lane, instead of speeding, traffic would flow both more smoothly and more safely.
Announcing tools to utilize ISS. Ardulab, is an Arduino modified with features to work on the station. Developed with NASA and Nanoracks. Enabled an 8th-grade class to do a plant-growth experiment for different light conditions in space, ready to fly. Takes up only ten percent of allowed volume, leaving remainder for experiments. Completely open source, hardware and software. Will be opening web site right after talk today.
Need competition in space industry, and known prices, to allow non-insiders to enter and put together business plans. #NewSpaceCon
Citing Arthur Clarke’s suggestion that vehicles need to be reusable fo make space affordable, from 45 years ago as Apollo 11 went to the moon.
Skeptics in the industry have scoffed at SpaceX goal of retroburning, entering, flying back to site and reflying. Both attempts would have been fine if they’d been on land, instead of in the ocean. Most amazing things was that it worked the first time, demonstrating the power of modern simulations.
When you start with a founding vision so far beyond the industry you have to invent a lot of new things (e.g., vertical landing on a planet, manufacturing propellant on another planet). Challenge is to see what is necessary to achieve vision, but come up with intermediate solutions that generate revenue. If you’re an incumbent not being disrupted, you’ll just incrementally improve, not go after revolutionary solution.

I should note that Matt and I had an extensive discussion at the reception this evening. He wrote that blog post after he went back to his room. I also came up with a good way to stake a claim to an entire asteroid under the OST that we thrashed out somewhat.
Art Dula just made some news at the New Space 2014 Conference. The Heinlein Prize committee hasn’t been able to come up with a winner this year, but they just announced a new prize, called the Heinlein Technology Prize. It’s a $10,000 award for a technology that has been tested in space, and shows significant promise to help commercial space activities. Winner will be announced in September.
My thoughts on what we haven’t done and where we haven’t been in forty-five years.
I’m sure you’re as shocked about this as I am.
A dozen things you probably didn’t know about it. Note the comment about weightless gestation and birth.
Probably safe for work, but you might want to avoid if you’re pregnant.
They resurrected it. It’s an interesting perspective from forty-five years later.
Why Americans suck at it:
American institutions charged with training teachers in new approaches to math have proved largely unable to do it. At most education schools, the professors with the research budgets and deanships have little interest in the science of teaching. Indeed, when Lampert attended Harvard’s Graduate School of Education in the 1970s, she could find only one listing in the entire course catalog that used the word “teaching” in its title. (Today only 19 out of 231 courses include it.) Methods courses, meanwhile, are usually taught by the lowest ranks of professors — chronically underpaid, overworked and, ultimately, ineffective.
Without the right training, most teachers do not understand math well enough to teach it the way Lampert does. “Remember,” Lampert says, “American teachers are only a subset of Americans.” As graduates of American schools, they are no more likely to display numeracy than the rest of us. “I’m just not a math person,” Lampert says her education students would say with an apologetic shrug.
Consequently, the most powerful influence on teachers is the one most beyond our control. The sociologist Dan Lortie calls the phenomenon the apprenticeship of observation. Teachers learn to teach primarily by recalling their memories of having been taught, an average of 13,000 hours of instruction over a typical childhood. The apprenticeship of observation exacerbates what the education scholar Suzanne Wilson calls education reform’s double bind. The very people who embody the problem — teachers — are also the ones charged with solving it.
…Left to their own devices, teachers are once again trying to incorporate new ideas into old scripts, often botching them in the process. One especially nonsensical result stems from the Common Core’s suggestion that students not just find answers but also “illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.” The idea of utilizing arrays of dots makes sense in the hands of a skilled teacher, who can use them to help a student understand how multiplication actually works. For example, a teacher trying to explain multiplication might ask a student to first draw three rows of dots with two dots in each row and then imagine what the picture would look like with three or four or five dots in each row. Guiding the student through the exercise, the teacher could help her see that each march up the times table (3×2, 3×3, 3×4) just means adding another dot per row. But if a teacher doesn’t use the dots to illustrate bigger ideas, they become just another meaningless exercise. Instead of memorizing familiar steps, students now practice even stranger rituals, like drawing dots only to count them or breaking simple addition problems into complicated forms (62+26, for example, must become 60+2+20+6) without understanding why. This can make for even poorer math students. “In the hands of unprepared teachers,” Lampert says, “alternative algorithms are worse than just teaching them standard algorithms.”
No wonder parents and some mathematicians denigrate the reforms as “fuzzy math.” In the warped way untrained teachers interpret them, they are fuzzy.
It’s a long, but interesting, and depressing article.
I should note that I was one of the kids who suffered from the “New Math” in the sixties, but I had a great algebra teacher in junior high (I forget her name, but she was a black woman), and good ones in high school as well. We actually learned calculus and analytic geometry from Mr. Troyer.

The more I think about this, the more furious I get that we have these worthless schools of “education” that don’t even teach teachers to teach.
SpaceX has released a statement:
After landing, the vehicle tipped sideways as planned to its final water safing state in a nearly horizontal position. The water impact caused loss of hull integrity, but we received all the necessary data to achieve a successful landing on a future flight. Going forward, we are taking steps to minimize the build up of ice and spots on the camera housing in order to gather improved video on future launches.
At this point, we are highly confident of being able to land successfully on a floating launch pad or back at the launch site and refly the rocket with no required refurbishment. However, our next couple launches are for very high velocity geostationary satellite missions, which don’t allow enough residual propellant for landing. In the longer term, missions like that will fly on Falcon Heavy, but until then Falcon 9 will need to fly in expendable mode.
We will attempt our next water landing on flight 13 of Falcon 9, but with a low probability of success. Flights 14 and 15 will attempt to land on a solid surface with an improved probability of success.
Some questions. Did they recover the hardware, or did it sink? If they didn’t recover it, how can they inspect it post flight to have that level of confidence in a low-refurbishment reflight?
So they’ve basically give up on ocean recovery. I wonder what “solid surface” they’ll attempt to land on? On Twitter the other day, I suggested flying back to Walker Cay, the northernmost island of the Bahamas, if they can’t get FAA permission to come back to Florida. Or perhaps they could try to drop it on a barge down range.
C’mon, folks! Didn’t you hear Michelle tell you that Barack was going to make you shed your cynicism?!! DIDN’T YOU UNDERSTAND WHAT SHE MEANT??11!!!

Some reflections from Bill Whittle.
It’s long past time to rethink NASA:
Unrealistically, the NRC committee recommends a 5 percent annual increase in NASA’s budget to carry out its recommendations, which are to spend billions for many decades with the eventual result of putting a few civil servants on Mars. My assessment, as a space enthusiast and a taxpayer? As Senator William Proxmire once famously quipped, on the topic of funding for space colonies: “I say not a penny for this nutty fantasy.” I don’t know what the future of human spaceflight is, but I do know that the NRC’s recommendations are not it.
Read the whole thing. It was written by someone who knows what he’s talking about, one of the great minds of our age.

Six questions from outside IT experts:
Ordering the destruction of a hard drive and documenting that process would be handled by trained, certified IT asset managers, according to IAITAM. But the group’s records show that at least three IRS IT asset managers were shuffled out of their positions around the time of the May 2013 inspector general’s report that detailed the agency’s targeting practices.
IAITAM said investigators need to “determine if these in-house IT asset managers were removed from the picture as the IRS email investigation heated up.
I predict that they’ll continue to stonewall.

OK, I read it. I disagree with his diagnosis of the problem, but I absolutely agree that we need to have a serious national discussion of why we have a government-funded human spaceflight program. That hasn’t happened in half a century. Until we do, we’ll continue to flounder, and be hostage to the whims of the rent seekers in Congress.
Eric Berger has Part 3 of his series up now:
Working with engineers at Johnson Space Center, as well as five other field centers, and using same tools NASA uses to estimate costs, Miller says, “We found we could put astronauts on the moon within a decade, inside the existing budget.”
The plan used the commercially available Delta IV Heavy rocket to conduct a steady stream of missions to the lunar surface, allowing humans to begin tapping into the moon’s resources.
“We briefed it to all the key NASA human spaceflight centers, giving them a chance to challenge the conclusion,” Miller said. “I thought it was a tremendous result for human spaceflight. We could have a plan that flies early and flies often.”
NASA never published the study and Miller’s contract wasn’t renewed.
Not enough opportunities for graft.
