    I think a lot of people understand the concept of light-seconds, which can measure distance in seconds.

    Allow me to introduce the gravity-second. 1 gravity-second of mass-energy is enough mass-energy to have a Schwarzchild radius of 2 light-seconds.

    Well you see, in 1793, 'Merica requested the metric artifacts from France so we could be metric too. France sent over a kilogram, but the shipment was lost at sea. And that was a little sad.

    All joking aside, US feet, inches, pounds, and so on have been secretly really metric since 1893.



  • Adding onto this. p < 0.05 is the somewhat arbitrary standard that many journals have for being able to publish a result at all.

    Is you do an experiment to see we whether X affects Y, and get a p = 0.05, you can say, “Either X affects Y, or it doesn’t and an unlikely fluke event occurred during this experiment that had a 1 in 20 chance.”

    Usually, this kind of thing is publishable, but we’ve decided we don’t want to read the paper if that number gets any higher than 1 in 20. No one wants to read the article on, “We failed to determine whether X has an effect on Y or not.”
