world, estimated to be 1.6 trillion barrels. With the development of new extraction methods such as steam assisted gravity drainage, which was developed in Alberta, bitumen and synthetic crude oil can be produced at costs close to those of conventional crude. Many companies employ both conventional strip mining and non-conventional methods to extract the bitumen from the oil sands. With current technology and at current prices, about 315 billion barrels of bitumen are recoverable. Fort McMurray, one of Canada's fastest growing cities, has grown enormously in recent years because of the large corporations which have taken on the task of oil production. As of late 2006 there were over $100 billion in oil sands projects under construction or in the planning stages in northeastern Alberta. Another factor determining the viability of oil extraction from the Tar Sands is the price of oil.

have large reserves at low production prices, newly found reservoirs often lead to higher prices; offshore giants such as Tupi, Guara and Tiber demand high investments and ever-increasing technological abilities. Subsalt reservoirs such as Tupi were unknown in the twentieth century, mainly because the industry was unable to probe them. Enhanced Oil Recovery (EOR) techniques (example: DaQing, China) will continue to play a major role in increasing the world's recoverable oil. Peak oil Peak Oil is the projection that future petroleum production (whether for individual oil wells, entire oil fields, whole countries, or worldwide production) will eventually peak and then decline at a similar rate to the rate of increase before the peak as these reserves are exhausted. The peak of oil discoveries was in 1965, and oil production per year has surpassed oil discoveries every year since 1980. Hubbert applied his theory to accurately predict the peak of U.S

have no notion what, if anything, was being said. And in this simple case, at least, nothing is being said. Someone might suggest that such a game, like the builders' language, is just too simple and/or primitive to qualify. But it is hard to see how the mere addition of further complexity would help. Reply Someone might argue that, if its rules are rich enough and advert often enough to ambient conditions, reference and predication will be recoverable from the game description. Suppose there is a rule that, whenever the waiter comes in, every third player shouts "Here, waiter," and is given a martini; whenever any player says "Mix please," s/he is passed the bowl of snacks by whoever is nearest it; and the like. One would then be tempted to conclude that "waiter" refers to the waiter and "mix" means snack food. So the game moves would have meaning after all. 82 Theories of meaning Rejoinder
before deigning to look at his phonograph. The Babbage rule would have deprived cryptologists of some of the most important features of modern cryptography such as the Vernam mechanism, the rotor, the Hagelin machine. Cryptologists must process a lot of ore to get something valuable—but so must diamond miners. In evaluating their ciphers, many inventors err by thinking that the cryptanalyst must retrace the decipher- ment steps in his solution and that, since some of these steps are recoverable only with the key, the cipher must remain inviolate. But the cryptanalyst, of course, comes in by the back door. Many inventors also invoke the vast number of combinations of keys afforded by their system as proof of its invulnerability. To exhaust the possible solutions would take eons, they contend. Of course the argument is specious. With 26 letters, an enormous number of different cipher alphabets is available for monoalphabetic substitution—
2. Many medical conditions and procedures (cancer treatment, for example) can render men infertile. 3. People who "know" they don't want kids change their minds. A lot. Just look at the number of vasectomy reversal procedures. And no, these procedures do not work well. Failure rates are high. 4. Above all, why not do it? If you can a ord it, it's a no-brainer for peace of mind. The potential downside of doing it (cost) is recoverable; the potential downside of not doing it is irreversible. Think it's easy to get someone pregnant? Sometimes. Most of the time, after looking at the numbers, it seems surprisingly hit-or-miss. To be clear, I think adoption is a beautiful thing. I just also want to have children who look like me, and I see no reason not to ensure both can happen. I want Mama Ferriss to be Grandmama Ferriss at some point, even if my testicles check out before I do. Call me old- fashioned.
