Amaurosis fugax: (from the Greek “amaurosis,” meaning dark, and the Latin “fugax,” meaning fleeting). transient one-sided vision loss. Many patients describe experiencing a black, gray, or brown window shade being pulled over one eye that then recedes after some time. It is most often caused by a temporary loss of blood flow to the retinal or ophthalmic arteries either from embolism or ischemia. It is often one of the first signs of carotid artery disease.
Getting hit by lightning gives you a special scar.
Lasting on the skin for hours or days, the Lichtenberg Figure is caused by the rupture of capillaries under the skin when the lightning current passes through it. They’re a major way that forensic scientists can tell a lightning victim’s cause of death.
Engineering Change, One Ad at a Time
Imagine this: In the middle of a billion-dollar televised spectacle of sporting violence, sandwiched between beer ads and gyrating plastic cheerleaders, surrounded by the latest Madison Avenue pleas for flavored taco shells and montages of young, hip people using that one new e-reader that everyone likes so much, 120 seconds of hope emerged.
Here is that hope.
It comes in the form of this Rube Goldberg-inspired ad for Goldie Blox, a series of building toys aimed at smashing the blinding pink wall put up around young girls and their toys. Maybe we should change it to Ruby Goldberg after this? Because they just owned it.
Here’s the deal: I don’t have to tell you how amazing this toy is (although I have before) or how great this video is (because that will be obvious when you watch it). What you need to do is go vote for this ad to be featured during the next Super Bowl!!!! Yes. Go vote. Go now, and go every day. The whole world has a chance to see this.
The power is literally in your hands. Use them to build some little girl’s future. Then who knows what she might build?
