Every hour they increase 10 percent in population.

Create a exponential equation using X for hour and Y for the population.

explain how im wrong and your right.]]>May 29th 2008 8:40PMhttp://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/http://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/After the first hour, the population is 138.6 (I suppose we should assume 137 because it is difficult to have less than one and greater than zero bacteria), so on the second hour, this population will increase by 10%; that's a 13.86 bacteria increase, so on the second hour, the bacteria population is 152.46 (or 152). Your equation only works for the first hour.
Haikibutsu's solution accounts for the change in population and increases by 10% every hour, so his solution is correct. Plugging it in we get Y(0) = 126; Y(1) = 138.6; Y(2) = 152.46
His answer is correct at all hours, So he is right and you are wrong. :'(]]>May 29th 2008 9:09PMhttp://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/http://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/hmm yes i rtoo was able to create this equation. but why exactly are we creating it?]]>May 30th 2008 4:44AMhttp://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/http://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/May 30th 2008 6:35AMhttp://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/http://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/May 30th 2008 9:33AMhttp://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/http://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/May 30th 2008 7:40PMhttp://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/http://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/

The problem can be considered notable in cultural trivia, as the only well-known paper ever written by Microsoft Chairman and billionaire Bill Gates (as William Gates), entitled "Bounds for Sorting by Prefix Reversal" and published in 1979, describes an efficient algorithm for pancake sorting.

It's completely ridiculous - it's like having a lot of computers, each taking one guess at the problem. And you have to do the DNA transformation, then culture the bacteria to see if anything grows.

There is nothing special about this solution with bacteria that hasn't already been done with molecular biology in bacteria before that is much more useful. This is just a small lab knowing how to market useless experiments to the scientifically illiterate.]]>May 29th 2008 11:38PMhttp://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/http://www.engadget.com/2008/05/29/bacteria-computer-is-good-at-math-even-those-pesky-story-proble/May 30th 2008 1:37AM
