More World Solar Challenge preparations

Across the world, solar car teams continue to prepare for the 2017 World Solar Challenge, turning dreams into functioning vehicles (Instagram memories from Michigan, Belgium, Jönköping, Nuon, Lodz, and me). Meanwhile, the road from Darwin to Adelaide is waiting.

Who’s your local team?


World Solar Challenge preparations continue

Across the world, solar car teams are preparing for the 2017 World Solar Challenge, turning dreams into functioning vehicles (Instagram memories from Twente, Aachen, Belgium, Stanford, Belgium again, and USC). Who’s your local team?


World Solar Challenge update for May

The infographic above (fifth in the series, and just a few days early) shows solar car teams that are likely to be entering in the World Solar Challenge this October, with my estimate of reported current progress (on a red–amber–green scale), taking into account recent social media updates. The team list has also been updated, and has a simpler traffic-light version ( RED AMBER GREEN ) of these estimates, together with more detailed news.

As well as building a new car, Principia are gearing up to race an old one at the FSGP in July, so they must be rather busy. Bochum continues to blog in German, and report that they are using plexiglas for the windows of their new car. Nuon have announced that their new car will have an autopilot (OK, that last one was an April Fool’s joke).

In general, teams should be well into construction by now. For some teams, I have seen no evidence that this is the case (which may simply mean that they are too busy to post). However, best of luck to all the teams!


Marching for Science #7

Interesting summary of the Science March from STAT:

  • Yes, it was a partisan anti-Trump event – “critics of the march who worried that it could turn scientists into an interest group to be isolated and ignored will likely feel their concerns validated after the event.”
  • It was mostly white – “There were [speakers] who were immigrants, trans, gay, Native American, black, Latino, young, and old. … But that audience itself was largely white.”
  • Industry science wasn’t there – “companies that are now marketing their ‘bold’ work in scientific discovery and developing new treatments largely lacked an official presence at the marches.”
  • People had fun – “lots of kids, dogs, and people dressed as dinosaurs. … and plenty of off-rhythm dancing to funk bands.”
  • What comes next is uncertain – “Will the march make a difference? Or will it end up as a historical footnote?”

Misquotes for Science

It’s a tough call, but the award for silliest statement at the March for Science has to go to the line “Dante said that the hottest places in Hell are reserved for those who remain neutral in times of moral crisis.” Dante never said anything of the sort, of course – the line is derived from something JFK said (“The hottest places in Hell are reserved for those who in time of moral crisis preserve their neutrality”), derived in turn from a chain of misquotes going back to Theodore Roosevelt. I’ve written before about Dante and Science, but suffice to say that in Dante’s Inferno, the worst regions are actually icy cold, and “neutrals” are not found there:

Please, let’s not have any “alternative facts” about Dante. The climate of the Inferno is important too.


Marching for Science #5

Further to my previous comments on the Science March, the graph below shows the (somewhat dubious) attendance estimates from Wikipedia for various cities (excluding vague counts like “thousands”), compared to the power-law predictor 0.47 D1.49 P0.78, where D is the fraction of the relevant state voting for Clinton last year (from Wikipedia), and P is the city population (also from Wikipedia).

The population P predicts 56% of the variance in turnout (not surprisingly), and D an additional 7%. Both factors were significant (p = 0.000000055 and p = 0.014 respectively). Prediction could probably be improved by using metro area population numbers for the cities, by using metro area election results (rather that state results), and by adding factors indicating the number of other marches in the relevant state (Colorado Springs, for example, was rather overshadowed by Denver) and the presence of universities (Ann Arbor, for example, is a university town). But the basic messages seem to be: Democrat voters do not like Donald Trump and Large cities attract large crowds. It would be interesting to compare the numbers here against other recent political marches which focused on different issues.


Marching for Science #4

Well, we’ve had the long-awaited Science March. It was, as expected, very much an anti-Trump event. Topics on people’s minds included threatened budget cuts, climate change, pesticides, intersectionality, immigration policy, defence policy, and the claim that climate change science had been removed from the EPA web site (it hadn’t).

Trump’s response to the march was “My administration is committed to advancing scientific research that leads to a better understanding of our environment and of environmental risks. … As we do so, we should remember that rigorous science depends not on ideology, but on a spirit of honest inquiry and robust debate.” I’m not sure if the marchers expected any outcome other than that.

There was the usual set of signs suggesting that peer-reviewed science is “true.” Which is odd, because cold fusion claims passed peer review, along with much other dubious work. Indeed, peer review has known problems. Perhaps, in public debate, we scientists should put more emphasis on replication.
