Cant speak for BT, but virgin use throttling instead of a cap If you get through more than some amount (typically a few GB's) during peak times your speeds will be throttled to 25% for a few hours, beyond that you can do what you want. And the top end services mentioned here dont even have that throttling....

this has come on a long way since you last saw it clearly. Mostly it's done with flash these days using the mouse to drag around or arrows if you prefer. Additionlly HTML5 viewers are starting to appear and mobile/tablet friendly viewers. See e.g http://360cities.net/

usually it just makes me laugh. With an MSci in physics anything that doesn't work is just blatant. Typically movies are full of unrealistic bits and it all ads up to help not take it too seriously. Turning action and adventure movies into comedies.

many times commenters have complained about the use of linear scales where something closer to a logarithmic scale would be appropriate, and now...

Especially in the fields you mention, you might want to look into latex based options such as beamer or powerdot. Both work in Lyx if you prefer not to hand-code the latex

i am perplexed as to why you chose to convert from SI units to light minuites. If you are going to convert from SI units it would make more sense to me to convert to plank units, in which case 1Km=16.16E39lp.

My attention was drawn a little while ago to the beta of this being around in the uk I downloaded it, and gave it a go and was pleased with the results, but wouldnt use it myself. Pro: The video quality was very good, and i had no latency issues, i tried out a racing game and an action game, both fast paced and i had no issue with input latency. It's clearly a fantastic way for those with lower end graphics cards to play games, You can also pay less than full price for games in exchange for access for a limited period, i.e rental for games you might only play through once. Con: You have to buy your games again to use within OnLive, which can then only be used in onlive. So you may have to pay again fro games you already own, and if you ever leave onlive youd have to buy again to regain access. Bandwidth. The video resolution was good but used every byte of my 10Mbps connection, rendering it unusable for anyone else, or if others used it i'd see a reduction in quality. Note the implications of 4.5+GB/hr for those with caps When my provider throttled me to 2.5Mbps, quality was noticably reduced (though latency was still good) and eventually onlive game up, stating i had insufficient speed. This is a fantastic concept, but as others have highlighted it effectively becomes another form of DRM, but allows gaming on non-gaming machines at good cost

If you crunch the numbers, the pixel density is equvilant to a 90 megapixel full frame sensor. The calculator on the page on diffraction on cambridge in colour suggest that this only becomes diffraction limited at about f/5.6 The pixel size is about 10um^2, which is larger than that of most compact point and shoot cameras
