  • A comment on Conversation: Why do we bother with spelling?

    May 5 2013: I agree - and I can personally throw in jokes about bald guys as well. Let's just be glad a spell-check program can get us out of these misspelling predicaments!

    A comment on Conversation: Infinity exists regardless of mankind's ability to conceptualize it.

    May 5 2013: Of course mathematics can not define reality - and irrational numbers like pi and phi prove this point exactly. In mathematics, those ratios go on and never end. In nature, they are whole.
    Kind of like the way calculus and digital audio approximate a wave form by slicing them into many small slices - but never truly take the shape of the wave.
    Reality will always be much larger than a few formulas on a page.
    As for Schrodinger's cat having 18 half-lives - that's a good one!
  • A reply on Conversation: Why do we bother with spelling?

    May 5 2013: Yes, I really got a mild headache from reading the misspelling sample. It lasted only a few minutes, thankfully. And dixlexia was a mild joke that only lasted a few minutes as well.
    I do wonder if a computer could be programmed to read through misspellings like we humans can. Might be a handy trick - like with that terrorist who was missed because his name was misspelled on the passenger list. Hmm...
  • A comment on Conversation: Does Technology destroy our relationship with Nature?

    May 4 2013: It all depends on which technology you mean and how it is used.
    Think of organic and inorganic farming. Both produce food, but each uses different technologies relating to the environment.
  • A comment on Conversation: Why do we bother with spelling?

    May 4 2013: I noticed that while I could read your post - slowly - it produced a mild headache similar to reading something out of focus. I also had to reread a few words and decipher them and replace them in to context. So though it may be possible to spell this way - it is slow and gives me a headache!
    I would NEVER read a novel or other long text produced in such a way - and I bet no one else would, either. So this study points to the fact that a few misspellings don't matter - but a lot of them are really annoying!
    This research might have some use in the field of dixlexia - if I spelled it right.

    A comment on Conversation: Infinity exists regardless of mankind's ability to conceptualize it.

    May 4 2013: An interesting subject, infinity. In English, it is a composite word: 'finite', meaning measurable, and 'in', meaning not. Therefore any infinity is not measurable - by definition. Whether there is a thing-in-itself out in the physical universe that is infinite - we can not know, and can not measure - by definition!
    In mathematics, we can always add one to any number, and therefore math demands infinity. But mathematics can not define reality, only attempt to describe it - check out Goodell's Incompleteness Theorem.
    Therefore, it is impossible to say with certainty whether infinity lies outside in the physical world - which is to say there is always an infinity of uncertainty. ( I'll catch you yet, Schrodinger's cat!)
    Infinite uncertainty leads to absurdity - which may be the word beyond infinity that I believe for which you were looking. Beyond infinity lies absurdity! ;-)
  • A comment on Conversation: What are some big social issues that need to be discussed, but aren't?

    Dec 7 2012: The overpopulation of the planet by humans. Our species' reproductive success is destroying our environment. But everyone adores children - as they should. So our global population - over 7 billion today - will continue to grow franticly, and in an undiscussed manner.

    A comment on Conversation: How can America wean itself from fossil fuels when fossil fuels are so cheap?

    Nov 21 2012: America will wean itself from fossil fuels - the day after we use the last drop!

    A comment on Talk: Ben Goldacre: What doctors don't know about the drugs they prescribe

    Oct 14 2012: I used to be unhappy that I lost my medical insurance. But now I don't feel so bad! Thanks.
  • A reply on Conversation: Is fighting climate change a losing battle?

    Oct 7 2012: Ah, Natasha. Hope is all we have ;)
