I eat much sushi, and have been ripped off before. For example, flying fish roe (aka tobiko), looks very similar to smelt roe (aka masago). The difference is that tobiko is much tastier and much more expensive than masago. Some establishments assume I can't tell the difference, but I can. Usually, when I correct their mistake, I am compensated with some free sushi.
It is a shame that no American space telescope will be in operation when Hubble takes its last pictures in 2008. The JWST will replace it in 2011, with a much different primary mirror design. it is an array of hexagons, rather than a single large mirror. One advantage is that the smaller mirrors are easier to shape because they don't warp under their own weight (as much.) JWST will have a 25 m^2 aperature, while hubble only has 4.5 m^2. Tinsley SSG, manufacturer of Hubble's corrective optics, is manufacturing the 18 Beryllium (lightweight) hexagonal mirrors. Wish them luck.
