• Why does the air contain sufficient oxygen to breathe, even over polar regions and deserts?

    Are wind patterns and microscopic plants in the seas sufficient to distribute oxygen, or are there other forces at work? Is the oxygen content higher in forests?

  • Olive oil -- what brands come in bottles that don't drip?

    I'd like to buy olive oil in an eight to ten ounce bottle that has an effective insert to catch drips. The olive oil I bought from Wal*Mart is OK, but the plastic rim on the bottle does a poor job of controlling drips, so the bottle has to be washed off frequently.

  • Why are so many questions getting deleted?

    I write a thoughtful answer to a serious question, and then when I go to post it, I see "This question has been deleted". Maybe we should ask the deleter to give a reason. Just now someone asked why her fiancé accuses her of arguing, when she doesn't think she's been arguing at all. I suggested that they talk about conflict... show more
    I write a thoughtful answer to a serious question, and then when I go to post it, I see "This question has been deleted". Maybe we should ask the deleter to give a reason. Just now someone asked why her fiancé accuses her of arguing, when she doesn't think she's been arguing at all. I suggested that they talk about conflict resolution in the abstract, some time when things were calm. What's wrong with that?

  • What happens to leftover food from catered events?

    We were at a large gathering where the hors-d'oeuvres buffet featured shrimp, cheese and crackers, and small fruit pieces. When dinner was served in another room, the hors-d'oeuvres platters were still partially full. I know it's the caterer's job to make sure they don't run out.

    We were at a large gathering where the hors-d'oeuvres buffet featured shrimp, cheese and crackers, and small fruit pieces. When dinner was served in another room, the hors-d'oeuvres platters were still partially full. I know it's the caterer's job to make sure they don't run out. Is perishable food like that left with the people who organized the parts, or taken away by the caterers? If the caterers take it away, do the employees get to take it home, is some of it re-used later, or is it thrown away?
