Submission + - Event-hiding 'Temporal Cloak' Demonstrated (gizmag.com)

Zothecula writes: Last year researchers at Imperial College London proposed that along with being used to cloak physical objects, metamaterials could also be used to cloak a singular event in time. A year later, researchers from Cornell University have demonstrated a working "temporal cloak" that is able to conceal a burst of light as if it had never occurred.

I understand the they used birds because of the evolutionary history, and crocs due to the age of their species and reptilian nature, but I doubt using the human body as a reference to the bodies of our millions of years old relatives would give a clear picture, and the same goes for this experiment. And it could be the case that the birds they used didn't evolve from t-rex, but rather some other (possibly completely unrelated) species of bird, which would skew the results. If I had to guess, I'd say that 30% is in the margin of error for this kind of work.

I use google aps for my email and I literally set up an account called spam@mydomain.com. I use it for all the things that require an email but that I don't want spamming my inbox. The spam account unsurprisingly gets a ridiculous amount of spam. I also have an alias for my account called NOSPAM which really throws off the email crawlers.

I don't know if it is contrary to code, but I've seen it done many times. They make special clamps that screw into the metal to make a good ground connection. A quick google search makes it seem like it isn't prohibited in homes in LA county, but I'm not a lawyer or electrician. http://www.ladpw.org/general/forms/download/1003.pdf?CFID=27792607&CFTOKEN=63377110

Comment Highly Suspect (Score 4, Insightful) 462

Have you ever tried to kill a harddrive with a magnet? It basically requires passing a rare earth magnet closely over the platters several times before the data is reliably damaged and if they had that kind of magnetic fields it would cause much bigger problems. And while I don't know to much about the properties EM radiation, I believe that magnetic fields don't interfere with radio waves.

My guess is that its the steel beams themselves are causing interference with the phones, that they incidentally had hdd failures (they have lived there for like 6 years), and the the steel beams have slight magnetic field because a small amount of current is passing through them (electricians like to ground to steel beams instead of running a ground line back to power box and putting to ground their) and they blame that weak magnetic field for their problems.

This is all purely speculation because they don't give any real details about the field.

It is called 'terrorism' and not 'demolition' for a reason, and I think that some fair sized bomb going off at about the same time at the capital and pentagon would cause a fair bit of terror.

Besides, I don't think you appreciate how big of a boom a couple pounds of C4 cause. The 'high' in 'high explosive' isn't a marketing term.
