So, the game of Scrabble now consists of, "on each player's turn, put all seven tiles down on the board, in any order and add up the score." That's so much simpler than the old version. I can't wait!
I'm sorry but if you leave the US, travel to a foreign battlefield and willingly enlist in the service of those who are fighting our country you've committed treason. Why should you be treated any differently than the foreign combatants whom are trying to do us harm?
I don't know. I'd be interested in knowing what the laws are for the crime of treason and how it is to be handled. What is the due process?
In general I agree, you have to do clinical tests. However, I don't see why patients should not be able to voluntarily accept this or other untested treatments provided that a full disclaimer is made. In a case where the approval of a treatment with a great deal of evidence in it's favor has long been delayed due to political or religious reasons as is the case with human stem cell therapies, working around the FDA might be a good thing.
This is actually how medical research studies are performed. The process is called "Informed Consent" and the prospective participant is given a full rundown on the proposed treatments, including a full disclosure of possible risks. However, the research study itself has to conform to various regulations and is subject to the oversight of various bodies who approve the study protocol and also the materials used in the consent process. There are quite a number of hoops to jump through prior to enrolling participants in the study.
On the other hand, offering an unapproved procedure as a treatment, rather than as the subject of a research study is a different thing entirely.
"I just got an $1800 ticket for texting while driving."
'for texting' is a prepositional phrase with the preposition 'for' and the object 'texting'. It takes a noun to be an object. 'Texting' is the name of an activity. Names are nouns. Note that I am talking about usage. As another poster stated, the word 'texting' has the form of a gerund which is a form derived from a verb that can be used as a noun. It can also be a verb. I am texting him a message right now. Some day that form may be recognized by the dictionary. Dictionaries don't establish language; they describe it according to accepted usage.
English is such a fun language. We can verbify nouns and subject verbs to nounification. Pretty soon, I predict there will one day be only one part of speech, the Interjection.
The propellant tanks are vented during the filling process. The boiloff that occurs during filling vents outside the tank. The hydrogen gas is piped away from the vehicle. The oxygen leaves via the vent cap on the top of the external tank that lifts up and swings away from the vehicle just before launch. Shortly before main engine ignition, the tanks are pressurized by closing the vents until they reach launch pressure.
It is true that compressing gasses can make them liquid at higher temperatures, but that isn't the case here. In fact, I don't know whether oxygen and hydrogen can be liquified at room temperature. I'd have to get a look at a phase diagram for them. Or perhaps wikipedia: http://en.wikipedia.org/wiki/Oxygen. In the table on the right, the critical point is 154.59 Kelvins. At temperatures above this, the liquid phase for Oxygen does not exist. Room temperature is well above this, by over 100 Kelvin. Also, the pressure required to liquify at that temperature is 5.043 MPa. Normal atmospheric pressure is 101.325 kPa. So there is no way to store liquid oxygen at room temperature.
Oxygen boils at 90 Kelvins and melts at 54 Kelvins. Hydrogen boils at 20 Kelvins. So, liquid Hydrogen is cold enough to freeze Oxygen solid at standard pressure. That means that liquid Hydrogen tanks need to be insulated so that Oxygen ice doesn't form on them. During filling of the hydrogen tank, the entire piping sytem and the tank itself is purged of all air using Helium, which is a gas down to around 4 Kelvins.
There is a lot of boil off that occurs as the tanks are filled and the and the tanks cool down to the fuel temperature. This is accounted for during the fueling process.
The property of cooling on expansion is exploited to make liquid Oxygen. Oxygen is pressurized to very high pressure, which makes it heat up. The pressurized gas is then cooled. The cooled, pressurized oxygen is then allowed to expand which causes it to cool enough to condense. (If it wasn't cooled enough to condense, the cooled gas could be used to cool another batch of pressurized oxygen to make it colder so that when it is allowed to expand, it would condense.) Once you have the
liquid, you can store it in properly insulated tanks.
The space shuttle runs on cryogenic fuel and oxidizer (liquid hydrogen and liquid oxygen) in the main tank. If the tank were not insulated, water vapor in the air would condense forming a think layer of ice which would fall off during the vibrations of launch. If foam striking the orbiter caused a loss of vehicle on reentry, just think what ice could do. If I remember correctly liquid oxygen boils at between 70 and 80 Kelvins. Liquid Hydrogen is even colder, so cold that the nitrogen and oxygen in the air would condense on the hydrogen tank if it were not insulated.
Maybe we need to go back to good-old fashioned text files. It was good enough back in the days of wood-burning computers; it should be good enough now.
Why dual boot? Gaming. It may not be a reason good enough for you, but it would be for some. I'd like it. Then I would ditch my PC for good. (And for me, a console won't cut it.)
You are assuming that the telcos will lower the price on the lowest tier. More likely, the current prices will apply to the lowest tier and higher prices for the higher tiers. In other words, the service you get now will be restricted, and if you want to restore it to previous levels, you will have to pay more.
>If you have 3 in 100 safe flights (97 disasters) and you make a change to have 30 safe flights in 100, that's 10 times safer.
In the sense that NASA has used it, that is 97/70 or approximately 1.4 times safer. To be ten times safer, you have to cut the risk by a factor of 10, from 97 failures out of 100 to 9.7. "10 times safer" and "1/10th as hazardous" do mean the same thing according to NASA.
Yes. A motor converts electrical power into mechanical power. A generator converts mechanical power into electrical power. In an ideal device (one with no losses to friction, windage, and electrical resistance), the shaft torque is proportional to the electrical current and the shaft velocity is proportional to the electrical voltage at the terminals. Mathematically, T = K_t * I. V = K_v * w. T is torque. I is current. V is voltage. w is shaft velocity. K_t is the motor torque constant. K_v is the motor Back EMF constant. K_t and K_v are properties of the motor itself, and, due to energy conservation, are numerically equal in consistent units, i.e. using Newton-meters for torque, Radians per second for rotational velocity, Volts for voltage, and Amperes for current. If the voltage of the car's electrical system is kept constant at 14.4 Volts, then increasing the electrical load will increase the current demanded from the alternator. Increasing the current will increase the shaft torque which must be supplied by the engine. More torque at a given engine speed means more power needed from the engine.
This response seems to exhibit a troubling assumption: that the "real fun" of an MMORPG comes after all the levelling is over, not in the process of levelling itself. That may be the case in most MMORPG's, but it is not good game design. The game should be fun at all levels and stages of character development, and the "new content" should address all levels and stages of character development.
Also, a significant part of WoW's player base are new to the MMO genre. A number of them, myself included, play WoW because they trust Blizzard to do it well and because it promised to not be a "typical" MMORPG in some respects, specifically, the level grind was not the primary focus of the game. I think that Blizzard should capitalize on this atypical audience and design games to fit them. I would definitely play another Blizzard MMORPG before I would consider switching to another brand, as long as it provided a compelling game play experience from level 1 to n, with a good storyline to back it up.
Keep in mind that, to be fair, you now have to add the cost of the dedicated game machine to the cost of the Mac, since you now have two machines doing the job that was done by one Windows-based PC. In addition, if the games one want's to play are only available on a Windows-based PC, then you essentially have two computers.
On the mechanical side of things, Power = Torque x Angular Velocity, so if the motor is maintaining the same torque as its speed increases, then the power increases linearly with speed (neglecting losses: friction, windage, electrical). However, the power required for acceleration is much higher than that required for maintaining speed, so after the vehicle reaches cruising speed, the torque required to keep it there drops, and so does the power.
If I remember right, I believe they replayed Commodore Decker's log in The Doomsday Machine episode of TOS and it was a video log. However, it has been a while since I have seen it.
Don't forget that all that hydrogen is bound up with oxygen as water. In order to get that hydrogen in a usable form, it is necessary to split the water molecules, and that takes energy -- at least as much as you can get by burning the hydrogen again. In other words, you need another source of energy to make it work. Unless you meant hydrogen fusion, but that is still a long way off.

My friend who got a degree in Software Engineering might be confused by your comment.
Where the heck did my sonic screwdriver get to?
That would be Videodrome.
Very good.
I'll just nip off and shoot myself.

Wow!
The liquid propellants are at normal pressure and are liquid because they are very cold. I refer you to this NASA fact sheet: http://www-pao.ksc.nasa.gov/kscpao/nasafact/count2 .htm#cryo
