Why P-values Cannot Tell You If a Hypothesis Is Correct

margeman2k3 To quote one of my professors... (124 comments)

"A p-value of 0.05 means there's a 5% chance that your paper is wrong. In other words, 1 in 20 papers is bullshit."

A San Diego court commissioner dismissed a traffic ticket on Thursday against a California woman who drove with Google Glass, a tiny computer mounted on an eyeglass frame. Court Commissioner John Blair said he was dismissing the citation against Cecilia Abadie on the grounds there was no proof her Google Glass was operating when she was pulled over in October by a California Highway Patrol officer

margeman2k3 Re:"Bar Mitzvah"? (233 comments)

That usage is pretty common in more observant communities.
The phrase basically translates to "child of the commandment" (or "subject of the law" according to some rabbis), so it's grammatically correct to refer to the celebrant as "a bar mitzvah".

Why Amazon Fights State Sales Tax, But Supports It Nationally

margeman2k3 Re:For the record (165 comments)

You think that's bad?
I worked at a cafe in Ontario, and we had so many tax rules that the company writing our POS software couldn't even get it to work properly.

It looked something like this:
Non-food items are charged 13% tax
Some non-food items are charged 5% tax
Most food items are charged 13% tax
Some food items are charged 5% tax
Other food items are tax free
If you spent less than $4 on certain food items, it was tax free
If you were buying "bakery" items (bagels, etc), then they were tax free if you were buying at least 6, but the total had to be under $4, and you couldn't buy a drink with it.

And this was just for a coffee shop.
I can see why Amazon would be willing to charge X% nationally, as long as they don't need to deal with crap like that.

Research Suggests Mars Once Had a Thick Atmosphere

margeman2k3 Re:First to say it (98 comments)

There was a short story I read like that, except I can't find it online.
Earth was prosperous, until war and climate change made it uninhabitable. There was a legend of another prosperous/utopian planet they could go to when their own became uninhabitable, so humanity gathers the last of their resources, and all of humanity (whatever's left of it at this point) migrates to Mars.
At the end, they find a plaque on Mars saying that Earth was the planet where humanity would go when their own planet (Mars) was uninhabitable.

Brain Zapping Improves Math Ability

margeman2k3 Re:4#10=23? (202 comments)

They used # as an arbitrary symbol, to represent some operation where 4#10=23.
Sort of the way that we use + as an arbitrary symbol to represent the operation where 4+10=14.
