DailyDirt: Measuring Important Stuff...

from the urls-we-dig-up dept

Measuring natural phenomena isn't always easy. There are a lot of interesting things that can be measured without a lot of fancy equipment, but some things can't be measured without just the right conditions and materials. Here are a few links on measuring some cool (or actually kinda hot...) things. By the way, StumbleUpon can recommend some good Techdirt articles, too.

    You failed to mention SOPA. Mike will be angry.

    "Did you know that the speed of gravity is about equal to the speed of light with an error of less than 1%?"

    Yeah but the 1% a masses all the wealth!

    Ba-da-bump

    The Earth is radiating a lot of heat (forty-four trillion watts!), but the source of that heat isn't entirely obvious.

    Really? Well send some of that heat this way so that I don't have to go broke buying heating oil this winter...

      Much of it comes from the trolls posting around here. Hot air to spare.

      Re:

      Well, the other thing is -- how accurate is that 44 trillion watts figure? I'm not sure how they arrived at that amount, so maybe they have that part wrong...

    "Speed Of Gravity" -- wow.

    Is this Earth gravity that is almost equal to the speed of light? Which means that, say Jupiter gravity must be over two and half times the speed of light. So Einstein was wrong that nothing could exceed the speed of light!

    Either that, or Jupiter is wrong about Einstein being a figment of its imagination.

      As it says in the post, the number is based on a binary pulsar system.

      Think of gravity as a wave. The wave travels the same speed, no matter what. The amplitude, however, changes based on mass.
