Weird math fact

A comic strip  (which you can see here after the jump) raised a mathematical conundrum that I’ve been trying to get my mind around.  Maybe you can help.

(1) 9 x 1/9 = 1.   Right?  That’s what the fraction 1/9 means.

(2)  1/9 = .1111111. . .  If you turn 1/9 into its decimal form, by dividing 9 into 1, the result is .1111111. . . [meaning a repetition into infinity]

(3)  9 x (.1111111. . .) = 1    Substitute the decimal form for  1/9 in equation (1).

(4)  .9999999. . . = 1      Do the calculation in equation (3).   9 x .111111. . .  is .999999. . ., another repetition into infinity.  The number by itself is short of 1, infinitely short, but you could go into infinity and it would never be 1.  AND YET, in the equation, .99999 in an infinite regress EQUALS 1.

How can that be? [Read more...]

Man as hybrid of chimp and pig

A prominent evolutionary scientist, Dr. Eugene M. McCarthy, is advancing a new theory about the origins of man.  He says that while it is true that a chimpanzee is our closest genetic relative, human beings have characteristics that are unlike any other primate.  For example, we lack the hairy hide of chimps and instead have just plain skin; under that skin, we have a layer of subcutaneous fat, whereas you never see an obese chimp; we have a protuding nose, whereas an ape’s nose is flat; and there are scores of other differences.  Dr. McCarthy postulates that human beings may be a hybrid of two different kinds of animal.  The animal that has those other characteristics–skin, fat, protuding nose, etc.– is the pig.

Typhoon kills thousands

One of the most powerful storms ever recorded hit the Philippines, killing some 10,000 people.  Go here to help.

Why we sleep

Virtually all animals sleep, but scientists have had a hard time figuring out why that is.  New research has apparently uncovered a major reason why our brains need to go out of consciousness on a regular basis:  While we are asleep, toxins that build up in the brain get flushed out.  Experiments with mice show that their brain cells actually shrink  so that there is 60% more space between them, allowing fluid to wash them more effectively, sweeping out dead cells and Alzheimer’s-causing plaque, as well as chemical toxic wastes.

How lucky we are that so many random mutations came together to make this happen so as to allow us to sleep!  I feel bad, though, about the animals that must have lived for millions of years before one of them, completely by chance, gained this survival advantage and spread it to all other species.  Before they could sleep, living organisms must have been really grumpy.

Why cats are the way they are

I’ve blogged about dogs.  But I also like cats.  They are cool, graceful little killing machines.  I also like what cat-haters don’t:  their independence.  Did you know that cats, unlike nearly every other domesticated animal,  cannot be intentionally bred?   Did you know that cats are the most popular pet in the world, with three-times as many cats as dogs?

British zoologist John Bradshaw, the author of The Behaviour of the Domestic Cat,  has a new book out:   Cat Sense.  After the jump is  an excerpt from that book.  Read it all at the link, but I have quoted a passage that shows how cats sometimes do, in fact, show affection to their human owners.  Sort of.

Has Bigfoot been verified?

Researchers are claiming that they have new photographic and physical evidence of the existence of the Sasquatch, a.k.a. Bigfoot.  Not only that, they have sequenced Bigfoot’s DNA, which reportedly shows that the creature is a hybrid human.

A consistent feature of Bigfoot sightings is that the observer smells an overpowering musky stench.  I am experiencing that right now, and it smells like a hoax.  Still, I get a big kick out of this sort of thing.  After the jump, I give you the website of these reports, a link to the scholarly article on the physical evidence and the DNA analysis, a news story, a photograph of Bigfoot, and a video.  Everything you will need for a Bigfoot extravaganza.
