Joke of the Day Intelligent Life
It was a celebratory mood with the folks at NASA… they had just made a scientific achievement of a lifetime. As they were uncorking the bottle of champagne, the lead scientist at NASA asked everyone to be quiet as a congratulatory phone call from the President was coming in on the phone. He picked up the special red phone (hot line) to the White House and with a broad smile on his face he said “Mr. President, after 12 years of hard research and billions of dollars spent, we have finally found intelligent life on Mars.” He listened intently for a second. As he did, his smile slowly disappeared and was replaced by a frown. He said, “But that’s impossible… we could never do it… yes, Mr. President we will try to accomplish the task you’ve now given us.” Then he hung up the phone. He addressed the crowd of scientists and engineers who were staring at him curiously. “I have some good news and bad news from the President. First, he is very proud of us for discovering life on Mars. The bad news is he now wants us to try to find it in Congress.”

Under this particular State's law, if an execution attempt fails, the prisoner is to be released, so the chemist was released. Then the biologist was brought forward. "Do you have anything you want to say?" "No, just get on with it." The executioner flicked the switch, and again nothing happened, so the biologist was released. Then the electrical engineer was brought forward. "Do you have anything you want to say?" asked the executioner. "Yes," replied the electrical engineer.

Joke of the Day The Scientists and God
One day a group of scientists got together and decided that man had come a long way and no longer needed God. So they picked one scientist to go and tell Him that they were done with Him. The scientist walked up to God and said, "God, we've decided that we no longer need you. We're to the point that we can clone people and do many miraculous things, so why don't you just go on and get lost?" God listened very patiently and kindly to the man. After the scientist was done talking, God said, "Very well, how about this? Let's say we have a man-making contest." To which the scientist replied, "Okay, great!" But, God added, "Now, we're going to do this just like I did back in the old days with Adam." The scientist said, "Sure, no problem" and bent down and grabbed himself a handful of dirt. God looked at him and said, "No, no, no. You go get your own dirt."

Joke of the Day The Learning Pill
An advanced society has figured how to package basic knowledge in pill form. A student, needing some learning, goes to the pharmacy and asks what kind of knowledge pills are available. The pharmacist says, "Here's a pill for English literature." The student takes the pill and swallows it and has new knowledge about English literature! "What else do you have?" asks the student. "Well, I have pills for art history, math, and world history," replies the pharmacist. The student asks for these, and swallows them and has new knowledge about those subjects. Then the student asks, "Do you have a pill for science?" The pharmacist says, "Wait just a moment," and goes back into the storeroom and brings back a whopper of a pill and plunks it on the counter. "I have to take that huge pill for science?" inquires the student. The pharmacist replied, "Well, you know... science always was a little hard to swallow."

D.O.S. #103 Thermal pollution occurs when human activities cause the temperature of lakes and rivers to rise. Why are fish most likely to be harmed by long-term thermal pollution of the water in which they live? The solubility of oxygen in the water decreases The solubility of carbon dioxide in the water increases The solubility of fertilizers, such as potassium chloride will decrease in the water The solubility of quartz crystals will increase in the water Answer: The solubility of oxygen in the water decreases Solubility of gases decreases as temperature increases (movement increases and oxygen and carbon dioxide bubble out). Bad for Oxygen, could for CO2 (which is what fish exhale) KCl is a solid when in fertilizer, so it dissolves as temperatures rise. Note KCl is also what they use for food processing, a substitute salt for NaCl and in higher concentrations - lethal injections
