    B How far outward can we rule out intelligent life?

    Points about relative weakness of radio signals well taken. Don't know what the sun's power output is in kilowatts, but probably more in any band than anything we'll build! Point about radio being obsolete - doubt. As technology progresses here on earth, electromagnetic spectrum frequencies get...

    One 50% bet is worse than fifty 1% bets?

    I'm confused about the initial set-up, and I think other people may be too. The one bet of $500, paying $500 50% of the time is clear enough. Net expectation $250, right? It's the 50 small bets of $10. What are the odds there? 100:1 or 1:1? I think people are confusing the fraction of the pot...

    How Do You Draw Correct Resonance Structures for H3CHCHC=NH?

    The 'original' drawing is missing a hydrogen atom, of course, which you added later. "Resonance" is the character of having TWO significant resonance forms - forms in which the atoms are in the same place, but the charges are not. The actual structure has the charge distribution as a mixture of...

    At what angle do you shoot a projectile so height=range?

    It's not 45 degrees for the same reason it's not 12, 38.987, or 756 degrees: it's not the right answer. Yes, there is some sort of similarity between the idea of equal height and distance, and the idea of an angle being equally far from vertical and horizontal, but you will find that picking...

    Can Hydroclauric Acid and Water Create a pH Greater than 7? Find Out Now!

    Not really. HCl, Hydrochloric Acid can only ADD H+ ions, and LOWER the pH. If you really want to nit pick, however... At temperatures below 25 degrees C, the pH of pure water is slightly higher than 7.0. At 15 C, it's about 7.16, for example. So if you take cold water, and any such a tiny...

    Why do electrons repel? - A basic question about the behavior of particles

    You are quite correct, in a sense. The search for underlying causes is, so far, a never ending quest. Science DESCRIBES how things behave, and discovers the rules. Sometimes it explains how it one behavior occurs by going a layer deeper. Example: First the rules of planetary motion - planets...

    What can I do to learn more about the life of a scientist?

    Two neat things about science - and research in particular: 1) It's a lot of fun - the world is a huge crossword puzzle, and you can fill in a few of the blanks... 2) You can get paid to go to graduate school! You have to be fairly bright, of course, or else just normally intelligent and be...
