15 Inaccuracies in Common Science Illustrations

 

Your high school teachers had the best intentions, but they likely featured educational illustrations on the walls of their classrooms that weren’t telling you the whole truth.  Our friends at Mental Floss painstakingly point out 15 gross oversimplifications found in common science illustrations …

All we have are these stupid tantalizing zircons and the scars on the face of the Moon.

Have we found life on Mars?

We can hope can’t we?  Organic material, or methane seems the most likely.  What a scientist would consider historic might seem like a yawn to many if not most non-specialists in that field.

I don’t know. We thought we might have before, and it disappointed (although some suggest we did find life before – the evidence is clearly too sketchy to get excited either way).
But in case you didn’t hear, NASA’s Curiosity had a big find that NASA is keeping secret as it tests and retests the data. They don’t seem interested in managing expectations at all, announcing that “this data is gonna be for the history books”. That’s quite a statement, isn’t it? More conservative guesses are that it’s organic material in the soil. I found this passage from that article interesting:
“Whatever Curiosity has found, it is not evidence for life on Mars. It can’t be. Curiosity is not designed to look for life. Grotzinger has stated this himself. In a NASA video about the mission, he says, “Curiosity is not a life detection mission. We’re not actually looking for life; we don’t have the ability to detect life if it was there.”
What if they brushed dirt off a small fossil? What if a little bug crawled across the screen and Curiosity followed it back to a Martian ant hill? Or lichen on a rock? “Not designed to look for life”? What an unimaginative way of thinking about things. They mean, of course, that it isn’t equipped to identify microbial life in soil. But Mars is a big planet, and even if most of it is blighted and uninhabitable that doesn’t mean Curiosity couldn’t have stumbled on something previous probes missed.
Of course, it probably isn’t life. It probably found the sorts of things it was sent to find. That’s where the smart money is. But “for the history books” is an intriguing turn of phrase, and I’ll be waiting expectantly until they announce exactly what we’ve got here.
So what do you think:
1. Will we hear in a couple weeks that there is life on Mars right now?
2. How will that change the way people thinking about their place in the universe?

Found In Our Neighborhood: A Planet Without A Sun

 

Article written by guest writer Kecia Lynn What’s the Latest Development? A paper soon to appear in Astronomy and Astrophysics reports the discovery of a “rogue planet” about 100 light-years from Earth. This planet, which is drifting in space without a sun to orbit around, is the nearest of …

I will no longer predict anything*

 

Earthquake experts around the world say they are appalled by an Italian court’s decision to convict six scientists on manslaughter charges for failing to predict the deadly quake that devastated the city of L’Aquila. They warned the ruling could severely harm future scientific research.

The court in L’Aquila sentenced the scientists and a government official Monday to six years in prison, ruling that they didn’t accurately communicate the risk of the earthquake in 2009 that killed more than 300 people.

The trial centered on a meeting a week before the 6.3-magnitude quake struck. At the meeting, the experts determined that it was “unlikely” but not impossible that a major quake would take place, despite concern among the city’s residents over recent seismic activity.

Prosecutors said the defendants provided “inaccurate, incomplete and contradictory information about the dangers” facing L’Aquila.

The court agreed, convicting the six scientists from the Italian National Institute of Geophysics and Volcanology (INGV) and a member of the Civil Protection Agency. It also ordered the Italian authorities to pay 7.8 million euros ($10 million) in damages.

Driverless Cars?

Are driverless cars a boon or bane?  Are they coming soon?  Here’s a comment from Tyler Cowan of George Mason:

transportation is one area where progress has been slow for decades. We’re still flying 747s, a plane designed in the 1960s. Many rail and bus networks have contracted. And traffic congestion is worse than ever. As I’ argued in a previous column, this is probably part of a broader slowdown of technological advances.

But it’s clear that in the early part of the 20th century, the original advent of the motor car was not impeded by anything like the current mélange of regulations, laws and lawsuits. Potentially major innovations need a path forward, through the current thicket of restrictions. That debate on this issue is so quiet shows the urgency of doing something now.

They may have crossed one of those regulatory hurdles. 

California Gov. Jerry Brown on Tuesday signed a law making it legal for driverless cars to travel on public roadways, demonstrating once again that the Left Coast has a way of prodding automakers to innovate faster.
