  1. I can't believe anyone would pass this. If 4H breaks this partnership, then you should be glad to get out. Oh. And if you were taught that 4H shows 8 tricks at equal vulnerability, then it's about time to drop out of the class and start forgetting what you were taught. This hand makes 7 tricks in hearts, and 0 elsewhere. End of story.

  2. That's definitely an accurate description of your hand :P but that's what happens when you don't check the meaning of bids before making them :) Of course, sometimes the online description and GIB's interpretation isn't the same and you end up in a different ridiculous contract. There's no way to get these right every time.

  3. Was is Edgar Kaplan who said, "what do you call an eight card suit? Trump." Hard to believe that a nine card suit would be any different.

  4. Not only is coal dirty, but anybody who took chemistry in high school can calculate that the CO2 emission per unit of energy is more than twice as high (2.26 to be more precise) for coal than for natural gas. Rik C + O2 -> CO2 = 393.5 kJ/mole of CO2 CH4 + 2 O2 -> CO2 + 2H2O = 890 kJ/mole of CO2 890/393.5 = 2.26, so per mole of produced CO2, natural gas yields 2.26 times more energy, or per given amount of energy, coal produces 2.26 times more CO2.

  5. As an ex-power sector Engineer i can say that there is no such thing as "clean coal".Coal is inherently dirty(Ash content).This content varies between 30%(anthracite) to 60%(bituminous) to as high as 80%(lignite).In modern power stations 99% ash can be removed thru' E.S.Ps(Electrostatic precipitators),balance is dispersed thru' chimneys.Though E.S.Ps are very efficient, but as coal volume required is huge (around 400mt/hr-depending upon calorific value of coal used-per 500MW),considerable amount of ash is dispersed into atmosphere thru' chimneys.Generally power stations operate on high ash content coal as low ash content coals which are considerably less available are primarily utilised in steel & non ferrous metals industries.'Clean coal' means reducing of ash in Coal by washing in coal Washeries generally situated near pithead,before supplying to power stations.This simply shifts point of origin of coal ash pollution.There is simply no free lunch when you are generating power.

  6. Most adds are repulsive. They pretend to sell sex and sunshine rather than the product advertised. Probably they work subconsciously anyway. I am only aware of a couple of instances in which I have actually bought a product after having seen an advert for it. One was a piece of jewelry, the other was a book. But it has probably happened dozens of times and I just forgot (or wasn't even aware). After the fall of the Berlin Wall I read that advertisers would have to take a more cautious approach in East Germany since East Germans are not used to advertisements and tend to take the view that if it is necessary to advertise a product, it must be faulty. So no sex and sunshine and unverifiable adjectives, just plain facts about the products. This is not 25 years ago so probably by now the East Germans have become braindead consumer sheep like the rest of us.
