Reusable Rockets

“If one can figure out how to effectively reuse rockets just like airplanes, the cost of access to space will be reduced by as much as a factor of a hundred. A fully reusable vehicle has never been done before. That really is the fundamental breakthrough needed to revolutionize access to space.” ~Elon Musk

Update: SpaceX May Try Land-Based Rocket Landing This Month

Here’s the SpaceX plan:

Slinkys and Change

First, watch this awesome slo-mo of a slinky being dropped.

Because it takes time for the tension to be released on the bottom of the slinky, it remains ‘held up’ while the top of the slinky falls. More subtly, the torsion is released faster than the tension and reaches the bottom first, uncoiling and rotating the bottom surface before the tension is released and the bottom finally begins to fall.

Social change behaves in a similar way. When a critical mass of thought or behavior changes state from OK to not-OK, it releases the social tension holding that thought or behavior in place. A wavefront of change moves through society from the change-point group outward to those most closely associated and onward from them in an expanding sphere of influence. The group farthest from the change point – either physically, socially or ideologically – is the last group to change.

The subtle part is that some part of that change may move faster. An idea, subordinate to, but foundational of the larger change may move through society first, followed later by large scale behavioral or ideological change. Examples might include the idea that tobacco smoking is unhealthy moving through society as a precursor to a later change that smoking is socially unacceptable, followed even later by policies and ideological reinforcement to discourage it. Another example being that information about stagnation in economic performance and high unemployment might move through society as a precursor to change in economic policy or even entire economic systems.

In the slinky, the inertia of the spring impedes the release of tension, which is why the bottom of the spring doesn’t fall at the same instant as the top. In society, not only does it take time for information to propagate, and for a critical mass of people to change opinion, but there is the additional impedance of disinformation, the inertia of entrenched interests hiding or distorting critical information in order to protect their power and income.

Finally, there is one other effect which is fascinating. Because the top of the slinky is released first, it the first thing to be affected by the change in state, therefore is the first thing to experience the acceleration of gravity. As a result, it actually outruns the tension-release propagating through the slinky, and reaches and passes the bottom of the slinky while it is still being held in place.

Again, this is mirrored in society. Those first to change have made large progress toward the new state of things before the last of the group has even begun to react. If they get far enough out front, they end up pulling the rest along even against their will. Revolutions can sweep through societies this way.

Hillary Will Not Be Elected

I’m going to predict Hillary Clinton will not be elected. I believe the majority of Americans are fed up with the lack of economic growth, high unemployment, increasingly bad race relations, politically driven riots, politically driven campus unrest, and an increasingly chaotic international situation. They’re going to vote for a change of government.

The real question is what to do when the GOP controls all three branches of the federal government. What should it do, in what order? Ted Cruz, for example, will immediately repeal what he considers all of Obama’s illegal executive orders. Nice. But of limited impact in the great scheme of things. What I’m concerned about are the fundamentals.

My list of fundamentals:
1. Replace the tax code with a lower, flat tax. Everyone pays at the same percentage.
2. Pass a balanced budget amendment. Include debt repayment in the budget.
3. Require all rules and regulations from any federal agency be approved by Congress. Require a cost-benefit analysis be included for each. Each regulatory agency and its existing rule set should be reviewed and scrubbed.
4. Pass welfare reform. Only the old and infirm should be on social benefits long term. Everyone else should be working and contributing to society. I would be open to CCC and WPA type programs to make the long term unemployed productive.
5. Repeal ObamaCare. Go to a market based healthcare and insurance system. Vastly reduce the legal hurdles and risks to providers. Include tort reform.
6. Repeal Common Core.
7. Review the costs and goals of every federal agency. Close every unnecessary agency. Start with the Dept of Education.

At the state level, I would like to see every Republican controlled governor-legislature team perform a full scale review of its school system: its administrative burden, its curriculum, its goals and its metrics. Consider voucher and competition systems to give parents a choice of schools and make schools compete for students.

People are ready for change. The future of the nation requires it. What good is attaining political power if it is not used?

Common Core

While looking up information on sedition and the sedition acts, I ran across this gem.
Never pass up an opportunity to indoctrinate:

Sedition

Your tax dollars at work. And government officials pretend to be shocked when no one trusts them with anything.
