The discovery was a fluke – a 10 minute telescope workshop for undergraduate students that led to a global scramble to acquire confirming images and spectra of a supernova in one of the most unusual and interesting of our near-neighbour galaxies.
The real question is do they really work, and if so how? I'm not aware of any technology that is capable of converting infra-red to visible light except with a significant input of power, which is obviously not available in the case of contact lenses.
Hopefully gas station pumps can continue to ask for a ZIP rather than a PIN. Just a personal preference.
That is really annoying for those who don' t live in the USA so have no zip code. It means two extra trips to the booth to get your credit card read and approved, and then debited with the actual amount of gas used. Almost all other countries use a PIN number (typically 4 digits) to approve credit card purchases done by machine but machines in the USA don't seem to be able to read them. I can't wait for the USA to catch up with the rest of the world.
But I suppose one can't expect any more of the only part of the world not to use International Standard road signs, A4 paper, 00 as the international dialling prefix, 230/240 volt mains, and metric units.
You know you've landed gear-up when it takes full power to taxi.
