Better Living Through Electricity

A fascinating article about the new field of transcranial direct current stimulation. Interestingly he experience the author felt was not what sensationalists would fear — an overweening self-confidence — but instead she gained the ability to calmly evaluate and solve an unusual problem (namely target shooting, a task she had never before attempted) without the accompanying chorus of thoughts telling her that she might as well just give up, that she was no good at this kind of thing, and just not an adequate enough person to solve these problems.

Me without self-doubt was a revelation. There was suddenly this incredible silence in my head; I’ve experienced something close to it during 2-hour Iyengar yoga classes, but the fragile peace in my head would be shattered almost the second I set foot outside the calm of the studio. I had certainly never experienced instant zen in the frustrating middle of something I was terrible at.

If you told me tDCS will allow to someone to study twice as fast for the bar exam, I might be a little leery because now I have visions of rich daddies paying for Junior’s thinking cap. Neuroscientists like Roy Hamilton have termed this kind of application “cosmetic neuroscience,” which implies a kind of “first world problem” frivolity.

But now think of a different application–could school-age girls use the zappy cap while studying math to drown out the voices that tell them they can’t do math because they’re girls? How many studies have found a link between invasive stereotypes and poor test performance?

As someone who experiences a great deal of the so-called “imposter syndrome”, all I can say is: where do I sign up?

Software Releases

In the past couple of months I have released new versions of NeuroLab and IronMeta.

NeuroLab version 1.2.3 is a maintenance release containing numerous fixes:

  • Fixed grid generation after resize.
  • Fixed grid viewer not always reflecting latest grid status.
  • Fixed grid saving and loading losing grid network.
  • Fixed activation gradient rendering for links of length greater than 1.
  • Fixed inhibition for links of length greater than 1.
  • Source code fixes and refactoring.

IronMeta version 2.3 contains the following:

  • Made generated code more general so it is now possible to combine parsers by inheritance or encapsulation.
  • Added the ability to use anonymous object literals in rules. They match by comparing their public properties with the input object’s properties.
  • Fixed a bug where string and char literals were not correctly handled in parsers whose input was not of type char.
  • Fixed an off-by-one error in input enumerables.
  • Generated code now compiles with Mono.

Unsettled Science

Sixteen prominent scientists give a little bit of perspective to the “we must hand our future over to faceless bureaucrats because the earth is burning up” global warming religion.

The fact is that CO2 is not a pollutant. CO2 is a colorless and odorless gas, exhaled at high concentrations by each of us, and a key component of the biosphere’s life cycle. Plants do so much better with more CO2 that greenhouse operators often increase the CO2 concentrations by factors of three or four to get better growth. This is no surprise since plants and animals evolved when CO2 concentrations were about 10 times larger than they are today [emphasis added]. Better plant varieties, chemical fertilizers and agricultural management contributed to the great increase in agricultural yields of the past century, but part of the increase almost certainly came from additional CO2 in the atmosphere.

A recent study of a wide variety of policy options by Yale economist William Nordhaus showed that nearly the highest benefit-to-cost ratio is achieved for a policy that allows 50 more years of economic growth unimpeded by greenhouse gas controls. This would be especially beneficial to the less-developed parts of the world that would like to share some of the same advantages of material well-being, health and life expectancy that the fully developed parts of the world enjoy now. Many other policy responses would have a negative return on investment. And it is likely that more CO2 and the modest warming that may come with it will be an overall benefit to the planet.

Imagine egalitarianism

One of the more delightful responses to a recent book by a seriously troubled, yet all too explicably popular, demagogue:

Sometimes the questions people ask or judgments they imply can make us chuckle, don’t they, my darling?

Well, who is in charge here?

We are.

Yes, but if push comes to shove, who is the leader?

We are.

But then who is the spiritual head of your home?

Only Jesus.
