Driver thanks man who hit him on purpose
Nice story and nice that the article had a tiny bit of science in the story, with another example of good work by an engineer.

More illusions by R Beau Lotto, lecturer in neuroscience, University College LondonThe middle tiles on the cube both have the same color, even though they appear very different to most of us.
The science of optical illusions
In this case the angles suggest depth and perspective and the brain believes the green table is longer than it is while the red table appears squarer.
The beautiful thing about illusions is they make us realise things are never what they seem, and that our experiences of the world shape our understanding of it.
Studying illusions can teach us several things. We can learn that it is easy for our senses to be fooled. We can learn about how the brain works. We can also learn how to take into account how our brain works to try and adjust our opinions (to be careful we are not just interpreting things incorrectly). It is amazing to see some of the wild guidance our brains give us. Normally they do a fantastic job of guiding us through our day but they have weaknesses that can lead us to mistaken conclusions.

In a fun example of appropriate technology and innovation 4 college students have created a football (soccer ball) that is charged as you play with it. The ball uses an inductive coil mechanism to generate energy, thanks in part to a novel Engineering Sciences course, Idea Translation. They are beta testing the ball in Africa: the current prototypes can provide light 3 hours of LED light after less than 10 minutes of play. Jessica Matthews ’10, Jessica Lin ’09, Hemali Thakkara ’11 and Julia Silverman ’10 (see photo) created the eco-friendly ball when they all were undergraduates at Harvard College.
They received funding from: Harvard Institute for Global Health and the Clinton Global Initiative University. The
sOccket won the Popular Mechanics Breakthrough Award, which recognizes the innovators and products poised to change the world. A future model could be used to charge a cell phone.
From Take part: approximately 1.5 billion people worldwide use kerosene to light their homes. “Not only is kerosene expensive, but its flames are dangerous and the smoke poses serious health risks,” says Lin. Respiratory infections account for the largest percentage of childhood deaths in developing nations—more than AIDS and malaria.

Unfortunately, says Gray, our schools don’t teach kids how to make things, but instead train them to become scholars, “in the narrowest sense of the word, meaning someone who spends their time reading and writing. Of course, most people are not scholars. We survive by doing things.”
I am a big believer in fostering kids natural desire to learn by teaching through tinkering.

Giant rats put noses to work on Africa’s land mine epidemic by Eliott C. McLaughlin
Prejudice against rats is “deep in our psyche” and has roots in the Middle Ages when the rodents were blamed for the plague, Weetjens said. He quickly cited Black Death’s rightful culprit: fleas.
…
The International Campaign to Ban Landmines says land mines and related devices were responsible for 73,576 casualties worldwide from 1999 to 2009. Campaign data from 2007 say there were 5,426 recorded casualties, with almost a fifth of them in 24 African countries.
…
The cost to train a rat is 6,000 euros ($7,700), roughly a third of what it costs to train a dog. Where dogs need expansive kennel facilities and regular veterinary care because of African climates, APOPO’s kennel facilities at Sokoine University of Agriculture in Morogoro, Tanzania, can house up to 300 rats. The rats see a single vet once a week and are much easier to transport than dogs, Weetjens said.
It is very sad what people do to each (setting up land mines to blow each other up for example). Thankfully we also do great things. I particularly like the engineering mindset behind appropriate technology solutions as I have written many times. They are also looking to have rats help detect tb and cancers. You can fund a rat for 5 Euros (about $6.5) a month to help free the world of landmines.

Get ready to re-think your ideas of reality. Join UCSD physicist Kim Griest as he takes you on a fascinating excursion, addressing some of the massive efforts and tantalizing bits of evidence which suggest that what goes on in empty space determines the properties of the three-dimensional existence we know and love, and discusses how that reality may be but the wiggling of strings from other dimensions.
