Blue Lego Block of Ambiguity 

The blue Lego-esque block shown in stead of Adobe Flash content when visiting a website in Apple's Mobile Safari browser. It has come to symbolize one of the greatest criticisms leveled against an otherwise highly regarded mobile browser capable of rendering most web content true to form. The debate over Flash's omission has swelled up once again with the introduction of the iPad which also utilizes Mobile Safari sans Flash support, albeit on far more capable hardware. While Apple claims to provide the "entire internet in the palm of your hand" their detractors are quick to remind the world that the "entire internet" includes quite a bit of Flash.

Blue Shift 

The increase in the frequency of starlight because of the Doppler shift. If a yellow star is moving toward you, it's light will appear slightly bluish. In outer space, blue shifted galaxies are rare. Blue shift can also be created by shrinking the space between two points via gravity or space warps.

Red shift is more common than blue shift because most objects in our expaning universe are moving away from us.
