Most microwaves have a power control. 90 seconds at power 2 or 3, wait 1 minute. Flip, 1 minute at full power. Wait 3 minutes. Serve.

There exist websites and books devoted to this appliance and how to use it correctly. This is a non-story.

Caveat: there are some nice physics going on in the explanation but only for the layman. Look elsewhere for the gritty detail we /.ers are used to seeing.

Submission + - The Death of Dark Matter's #1 Competitor

StartsWithABang writes: Since as far back as the 1930s, observations of the largest structures in the Universe have shown us that there's a discrepancy between the amount of mass that can be inferred from the starlight we see and the amount of mass that we know must be there due to its gravitational effects. Either there's some new, unseen form of matter that isn't present in the Standard Model of particle physics — dark matter — or the laws of gravity are wrong and need to be modified. The leading candidate for the latter option is TeVeS, the first relativistic formulation of MOdified Newtonian Dynamics (MOND). Well, the first observational test capable of distinguishing between TeVeS and General Relativity is complete. Spoiler: Einstein wins again.

Correct, they are not the same thing.

Tagging can contain the structure of a folder system with inherant deduplication of data. 1 tag per foldername contained in path. Done. Then you can add the file to another "folder" by adding a tag. Search for your regular foldername and you have your "folder" without browsing an entire hierarchy of foldernames.

That being said I don't really tag my files - I use folder hierarchies and don't worry about dupes (this is /. after all). I can see the expanded utility of tags though especially from a "searchable data" perspective.

If you were to create a world AND place yourself* in it, then yes you would be subject to its laws.

*yourself in this context could be a digital brainscan or equivalent representation as long as the representation has what you posess-free will(maybe) consciousness etc ...

First off IANAP.
To throw some variables out there:

As I understand it the conjecture under review is:
M(rest)=M(grav)=M(inertia)

Implicit from Einsteins field equations,
R_mu_nu - (1/2)g_mu_nu*R + g_mu_nu*GAMMA = (8pi*G/c^4)*T_mu_nu

somewhat like the next layer beyond E^2=m^4c^4+p^2c^2 (lorentz invarient form iirc?)

I wont see it in my University courses for a few years but from online lectures and pdfs i have a bare understanding of the implications if the conjecture is false:
1. The dark matter problem 'could' go away if the conjecture is found to be false. Not too likely imo

2 If the different masses are NOT equivalent then here there be dragons! i.e. new interesting physics underneath-perheps leading to new propulsion systems.

I'm sure someone will pipe up and correct me if i'm wrong enough.
