Top Scientific Breakthroughs of 2009

Wired has posted their favorite scientific breakthroughs of the past year. The feats include things like the confirmation of element 114, a cancer-detecting breathalyzer, the power of jellyfish and more. What other discoveries should have made the list and what might we look forward to in 2010? "Also this year, researchers at the University of Washington cured two adult monkeys of colorblindness by giving them injections of a gene that produces pigments necessary for color vision. After the treatment, the animals scored higher on a computerized color blindness test. In the coming years, gene therapy will be tested as a remedy for all sorts of inherited diseases, cancer, viral infections and even high cholesterol."

Normal mirrors do not reverse!

[Kupfernigk]

Mirrors do not reverse left-right as was explained most clearly by Richard Feynman. If you turn a book round and then look at it in a mirror, the actual text you see in the mirror is the same way round as it currently is in the book (you can prove this very easily - write in felt tip on a plastic bag and try that. You will see that the mirror writing, and the writing seen through the back of the bag are exactly the same way round

The answer to the question, why do mirrors reverse left/right and not up/down is simple: they do neither. A few seconds of ray tracing show that they reverse front to back.
