The Lockheed L-1011 TriStar has been chosen by six of the Free World's ten largest airlines that fly wide-bodied jets. That's good to hear If you I ive near an al rport. TriStar is the quietest big jet in the world, as certificated by the U.S.A'.s Federal Aviation Administration, thanks to its Rolls-Royce RB.211 engines Rolls-Royce designed the RB.211 with fewer moving parts. It wrapped much of the engine sound in an insulating shroud of air Other sounds are muffled and absorbed by an acoustical honeycomb. TriStar shrinks the noise area around airports 920/0.

Older four-engine jets affect an area of about 62 square miles With TriStar that occurs during takeoff over an area of less than five square miles. (The noise diagram above shows the area difference between TriStar and older jets.) Even if you live or work within that smaller area, TriStar still brings welcome relief because it generates less than half the annoying jet noise of older jets. *Based upon passengers carned 57 . . .

It takes off with twice the passengers of older jets. So ai rports allover the world will have quieter takeoffs. And fewer of them Or at least, fewer than there would be If only the smaller noisier jets were flying TriStar's long-range good neighbor policy. Rolls-Royce is increasing the thrust of the RB.211 engines to 48,000 pounds. This means TriStar will be able to provide nonstop service to cities as far apart as 5300 statute miles.

"On September 15, 1842, the British Astronomer Royal, Sir George Biddell Airy, K.C.B., M.A., LL.D., D.C.L., F.R.S., F.R.A.S., responded to a query from the Chancellor of the Exchequer. The government was considering funding an invention of one Charles Babbage. Should Parliament support the construction of the analytical engine--the first mechanical calculator and predecessor to digital computers? What would be the value of such a device? The learned astronomer's one-word reply: 'Worthless."
Can't make up your mind about new music? '"Ringo" [i.e. HOMR Now: Firefly] is a personalized music-recommendation sytstem,' Professor Pattie Maes of MIT's Media Laboratory writes in the July 1994 'Communications of the ACM.'
Of all the software agents she's considered, 'This one might have the best potential to become the next "killer application" '. Along with other entertainment-selection agents, it will help you select movies, books, and television shows, by correlating your tastes with other intelligent agents.
Now, I don't need a computer program to tell me what books or music I'll like. Friends, reviews, and browsing work just fine, thank you.
Intelligent agents are a fantasy sprouted in the tomorrowland of MIT's medial laboratory. They're believable enough to generate heavy grants for big-name researchers. But I wonder of Professor Airy's prediction may now be coming true, a century and a half late."
Photographs can be supplied as A4 or A3 prints or as digital copies, which will be sent by email. The online watermark does not appear in photographs purchased. All photographs are subject to copyright restrictions and may not be published without permission.
We use a high resolution 50 mega pixel Canon camera, mounted on a Guardian stand, which allows us to capture A0 plans comfortably without losing any clarity or definition. Plans larger than A0 are digitally stitched using Adobe Photoshop by experienced reprographic staff. Images are captured at a minimum resolution of 300dpi as TIFFS using Phase One capture software.
Paper copies at A4 and A3 size are printed on 120gsm high quality matt paper using good quality printing ink.
Paper copies larger than A3 (A2 up to A0) are printed on 170gsm high quality matt coated paper, using UV inks which do not fade or lose colour over time.
