Comment Re:In Defense of Matlab (Score 1) 119

I own a copy of Matlab, but am moving more and more stuff out of it.
It integrates with command line very poorly (on windows).
The java interface parts look like shit.
The language sucks for real development work.
They want to pay them a fee to retain the future ability to purchase toolboxes, even though I don't want support.
The only thing I am still using is the griddata function because it is better than octaves.
Most of my work is now in python with gnuplot.

Or alternatively,
People who disbelieved the mountains of different evidence supporting anthropogenic climate change will put this latest piece of evidence in the same mountainous pile of ignored evidence.
People who have taken the somewhat less convenient path of rationally assesing the available scientific evidence will still accept the evidence, and and would have continued to even if the CRU had been found guilty of intentional gross fraud and conspiracy.
Then again CRU could have been one cell in a world wide scientific fraud conspiracy group intent on world domination. But this inquiry and the other one found that they wern't - which makes sense : if scientists had wanted to have power and money they wouldn't have studied science over politics or finance.

Comment Re:Problem is world democracy (Score 1) 865

Small countries scuttle a deal ? What version of history are you using ?
The DEAL agreed by 117 countries was stabilization at 350ppm.
Then the countries that have the historical responsibility for the problem, are the major current cause of the problem decided that they should also be the future cause of the problem, and couldn't agree to anything that might cause them to show leadership in their own countries.
Are you seriously suggesting countries like Maldives and Tuvalu should have signed up to what would have been a suicide pact for them with the rich nations, just to be cooperative ? That is not democracy. That is pure self interest.

Comment Democracy is giving us want we want (Score 1) 865

Democracy is really good for giving the people what they want, which is really successful in peace time.
Unfortunately in this case where a problem is so large we need to get on a planetary war footing, but what they want is willful/plausable ignorance of the subject.
Politicians and the media are forced to supply, untill things get really bad, and then history shows capable leaders will turn up.
I doubt Winston Churchill would have been elected in peace time.

Unfortunately the dynamics of the climate and the masking by aerosols of the magnitude of the forcing mean that if we wait for things to get even worse with a few more years of willful decadent opulent ignorance, then we are commiting to some far worse problems after we start to take drastic action. The magnitude of these problems depends on which model of ocean mixing is accurate and where in those fat error bars the value of aerosol forcing turns out to be. On top of that there is the potential for tipping points that could arrive before or after we start to take action.

Any sensible person with this information would have to say act now.
Better to stick with denial.

Comment Re:Something I don't understand about the hot one. (Score 1) 102

I could guess that they are determining temperature by finding the peak wavelength of light using Planks law.

If there was a smaller body in front of the bigger body, the spectrums are added ( or spectrum of big one * (size of bigone - size of small one) + spectrum of small one * size of small one) which might move the peak wavelength slightly. This would work for both a hotter and colder small body, and tell you size and temperature, given sufficient precision in wavelength and amplitude.

Comment Or else ... (Score 5, Informative) 316

Or we could just have a brief and rather blunt conversation with our friends in the coal, oil and beef industries.
Which is what world leaders are tiptoeing around trying to avoid, pretending terrestrial biofuels were an option, pretending carbon sequestration is an option. All of this stuffing around to avoid some uncomfortable conversation about facts that both the politicians, the people and the companies know are true.

Must we be stupider as a species than our individual parts ?

I live in Australia too.
Fuel tax has not gone directly to roads since the seventies - it goes into general revenue.
Rego + fuel tax does not fund roads.
Local, state and federal gov all subsidise the building and maintaining of roads. Federal receives fuel tax, state receives rego. All three levels of government spend more on roads that they receive from motorists.
Add to that our activities in Iraq, exclusion from the proposed CPRS (Carbon pollution reduction scheme), and the hospital costs to handle all these obese Australians, and most cancers are reduced by an active lifestyle.
We also subsidise our car industry to produce technologically backward large cars.
No. Cars are recieving massive subsidies at the expense of cyclists.
Also look around at all the extra infrastructure - traffic lights extra lanes, car parks, parking spaces, garages etc, that are required to support this system.
Bikes cause less wear and tear, require far less road to be built, and require less insurance because they can damage less.


But don't think you are incorrect because of mere facts, take comfort being surrounded by a large percentage of Aussies who share your beliefs, which is why politicians feel the need maintain this system.

Sounds like you fear being run up the back of in your car.
And that is the reason why you don't like slowing for bicycles who fear being run into from behind.
So your solution is for everyone to drive faster.
This will result in ever increasing speeds. Not sensible. Why not slow down and if you can't beat bikes, join them.
Re your assertion that bikes can only ride in bike lanes, besides being ridiculously impractical, is likely incorrect :

I looked at what I thought would be the most backward states and they all say bikes have equal rights.

I'd gladly pay rego and insurance for my bike. It would be a lot less that that for a car.

And car drivers can pay for the oil wars, hospitals for the obese caused by inactivity, lung disease caused by emissions and most cancers which are reduced by active lifestyles.
And the massive government subsidies funding roads in most countries, the benefits of which I don't think you can argue is equally shared by bike riders, who cause less wear and tear and require less road space.
And pay for the realestate and mainetence costs for all the car lots, car parks, traffic lights etc whose costs are currently socialised for the benefit of car drivers.

I really don't think bike riders are free loading.

Comment US provides propaganda for enemies (Score 1) 240

US is very much like the bad guys in lots of hollywood movies.

e.g. Terminator, Star wars, Independence day

All feature large superior force with evil weapons attacked by human freedom fighters (also known as terrorists lately).
These movies can all be used to incite freedom fighters to fight the evil impersonal overlords that attack without putting their own lives in jeopardy.
There are going to be some confused kids when they see which side is flying the obligatory US flags in some of these movies.

Comment Basic calcs make this impractical (Score 1) 296

A quick calculation of the pressure required at the top of the inflatable tower to hold the mass of the rest of the tower up ...
Force = ma = 800,000,000 kg * 9.8
Pressure = Force / Area
Pressure = 800,000,000 kg * 9.8 / pi * 1 x 1 ( because it is 2 meters across, it has 1 meter radius)
= 2.5 GPa

Thats a lot of pressure, and with such I tall cylinder of air the pressure at the bottom would be even greater.
