I was thinking something like it spins along a dimension so small it can't be detected without a particle collider the size of the solar system.

The difference between that and job interviews is that we are forced to pay for this crap via taxes. It is literally a black hole for tax-dollars. I still say cut government funding for research by 90% and watch it get fixed automatically a

I would have preferred a reference to the paper making the prediction, but that sounds very vague so whatever.
373.
by nonbel 8y ago
There is a spectrum of precision regarding the predictions you can make. At the high end is a point prediction, at the low end is "x is correlated with y somehow". In between are intervals of various sizes.

I'd say both organic and inorganic chemistry are hard sciences since they make precise predictions about what will happen. But not biochemistry, and definitely not cell biology or molecular biology. I also wouldn't consider math a

Not at all. In the hard sciences you can run reproducible experiments and have mathematical models used to make precise predictions and come up with "natural laws". Biologists were moving in that direction up to 1940 or so but tha

Yea, I have always found academic machine learning papers to have very little value. The helpful people create a github and write a blog post, not publish a paper.

You've got it wrong if you are worried about the greenhouse effect. If humans don't extract and burn the gas, the gas will be released as-is into the atmosphere by beavers thawing out the permafrost.[1] Natural gas is actually a
