The nine circles of scientific hell
This graphic is awesome. Be sure to read the accompanying article from Perspectives in Psychological Science.
The Divine Comedy of Dante Alighieri is a classic of world literature and was the first major work in the Italian language. In the first book of the trilogy, Inferno, Dante offers a tour of the nine increasingly horrible levels of Hell, in which the wicked are tormented forever in ways corresponding to their sins. But Dante lived before the era of modern science. Perhaps it is necessary to update his scheme to explain what happens to those guilty of various scientific sins, ranging from the commonplace to the shocking

35 years later, Voyager spacecraft nearing the edge of the solar system
In the fall of 1977, NASA launched the two Voyager spacecraft, which were designed to study Jupiter and Saturn and then continue on to the limits of the solar system. Today, they are each more than 14 trillion kilometers from the sun and nearing the “bowshock,” the transitional region where the solar wind collides with gas from interstellar space. Within five years, the Voyager crafts should be completely clear of our solar system’s influence. That far, light must travel more than 30 hours from the sun before it reaches the spacecraft.
What’s especially interesting about the Voyager expedition is the backstory behind the mission. Rocket scientists around the time of Sputnik were trying to design a rocket that could overpower the sun’s gravitational pull, a very tough task. A trip of more than a few months using this brute force method was out of the question. Cue Michael Minovitch, who in 1961 set out to solve the three-body problem, the question of how gravity from both the sun and the Earth would impact a third body, in this case the spacecraft. Some of science’s greatest minds, including Newton, were stumped by the task. However, with the use of one of the first computers, Minovitch was able to demonstrate how exploiting the sun’s gravitational field to slingshot a spacecraft deep into space. One of Minovitch’s simulations used this slingshot approach to accelerate using the gravitational fields of the sun as well as Saturn, Jupiter, Uranus and Neptune. The planets were only on the same side of the solar system in 1977, and the same opportunity wouldn’t present itself again for 176 years. Scientists luckily realized the potential in Minovitch’s idea, and launched the Voyager crafts with enough power to last for decades in space and with instruments to study the solar system’s furthest reaches. Today, although the signal from the spacecraft represents only a billionth of a billionth of a billionth of a watt once it reaches Earth, the ships keep sending back data and contribute to new discoveries.

All of this hurricane talk has put me in the mood to talk about global warming…

Zoox(anthellae)
Lots of you ask me advice about careers in marine biology/ conservation. This is a company that specialises in career development for those looking to get into the conservation sector. Having done their Zoox Experience Programme this year, they helped me focus my goals and develop skills missing from my CV.
Check out their Facebook page for regular job updates, ask advice and generally keep up to date with the latest in Marine Conservation, and what I’ve been up to lately (i.e. why I haven’t been a-Tumbling.
Good initiative. Thank you for the tip.
