No, you are quite confused. Species of leukocytes often squeeze through capillary walls to exit the bloodstream, wander around in the tissue, and go back. The immune system is very active in the lung, it would be absurd for it to be inactive in a site so exposed to pathogens (frequent inhalation, thin epithelium). In fact, the inflammation-like context is one reason that the lung is a common site for metastatic cancers.

Now "dealing" with the roots, I don't know. Would you expect the macrophages to swallow the roots whole? B-cells producing antibodies to aggregate the plant? Normal plants already survive much harsher environments than mere immune systems, they grow on soil exposed to the elements.

B and C are not conceivable, no.

If they rounded up every single U-Boat, I don't think it would matter whether the Germans know if it is broken- seeing as how they wouldn't have any U-boats left to send secret messages to.

Grade 9... High school? You didn't know basic algebra in HIGH SCHOOL? Were you homeschooled in Smalltown, Minnesota? I was taught single variable equations in grade 4 and was starting Calculus in grade 9.

I had a similar thought. Why is his opinion on the subject being trumpeted as some sort of divine truth? His work has very little to do with the actual practical challenges (both in terms of engineering, finance and convincing the government(s)) involved in leaving Earth. It has very little to do with its ecology and how much damage it will be able to sustain. It has very little to do with history or global politics, and how likely some manner of dark age is to occur in the future.

Quite simply he's the equivalent of my grocer harping on about string theory and his own private "breakthroughs" on the manner. Why is this news? Is it because he does this weird magic science stuff with them stars, so he must know all about getting to them?

Someone already has.

No, the FBI exists to protect serve the public whose tax dollars pay its salary. Just because the system is corrupt and the voters are clueless does not suddenly invalidate the ideals and principles the government was founded on.

Why do you Americans stand for this? Some ass at the head of an agency says "Oh yeah? I can't do it? Who's gonna stop me?" and all you do is bow your head and take it because "hey, can't argue with that".

How does turning auctions into some stupid gamble with randomized durations introduce transparency or accountability? How on earth does turning a trading platform into a casino introduce ethical considerations? I'll concede on the profits, but the rest of what you say is simply ridiculous.

Then set it above $50.01, but below $60! God, what is wrong with you people?

Typical eBay whiner.

Microsoft Office is indispensable to any work place. What planet do you live on?

You appear to believe that teaching ability is an externally originating quality, such that when the blessing of the gods of teaching falls on a professor, his endeavors succeed. I am afraid this is (probably) not true. The difference between effective and ineffective teaching comes down to the choices made in methodology (assuming equal knowledge on the subject between compared teachers) and a large majority of those are discrete, tangible choices. Like not using a page of text on the handout when a single picture would do.

I'd like to challenge your claim. While you could obviously achieve a lot despite being restricted to a chalk and board, inability and unwillingness to use more effective tools at his disposal is precisely the feature of a bad teacher. It is not the only feature, but it is one of them.

Well, if you assume price*copies sold is constant, sounds like he can make a maximum of 6250$ per week at 50 cents per copy, with your figures.

To be serious, dear Cruciform: Nobody is buying your game at 2$ but they are getting it for free. Note how the market is bigger than 25k, which means many people won't even play your game for free. I bet some of those 25k downloaded it, tried it, and uninstalled it. But even assuming all of those 25k people became addicted within moments, you still have to face it: Your game is just not that good. Most people would literally not play it unless you paid them to.

If you hate it so much why don't you drive a coal truck too? Sounds like you think you have more than enough skill than necessary, would work less, and earn more. Let me guess, either your brother is a very special case, or you tacked on an extra 0 in that number.

When you have last seen a job listing for "CEO of a successful company"? You are ridiculous. There are three ways to end up in that position: (1) Be born into a family with lots of influence to begin with, (2) rise up through the ranks to get to the position, (3) start your own business and make it huge. 2 is very hard, and 3 is obviously very risky- many businesses do not succeed. The boss with a million dollar salary is reaping the rewards of his past success in face of the risks taken at the time, not just his current performance.
