Comment Re:I actually believe Rossi (Score 1) 426

Something that makes this new paper fit in with all previous "scientific" papers I've seen on cold fusion:
- No error analysis. Just straight numbers and tidy graphs with no error bars. The couple of uncertainty ranges added to make it look better were pulled out of their hat.
- Pictures of the experimental apparatus, but no diagrams of what's actually claimed to be going on.
Also noteworthy:
- Most of the authors have never been seen before on arxiv.
- The one who has posted a lot to arxiv (Essen) has mostly produced articles relating to fractured ceramic vessels.

Comment This is not a new idea. (Score 2) 381

A friend of my in the 70's who was a math grad student at the time was playing with taking the absolute value of gamma = 1 / sqrt(1-v^2/c^2) to avoid the imaginary aspect of the term. Only at light speed was a massive particle forbidden. The square of the momentum remains real. Other results were the same: Things become less energetic the farther you get from light speed in either direction. At sqrt(2) times c, your relativistic mass and time are the same as at rest and your subjective trip time matches that of distant observers. Finally, at infinite speed you have zero mass and your subjective trip time is the same as the distance traveled (times c, of course). I seriously doubt my friend was the first person to come up with this. What's different with the new publication, AFAICT, is that these guys have an eager university press office. I love it when the press release folks feel obliged to mention that the work appears in a "prestigious" journal.

Comment Higgs Boson mass vs. Top Quark Mass (Score 2) 170

I'm curious what's going on such that the top is heavier than the Higgs rather than the other way around. All I've been able to find is people asking why the top was found first. *That* I understand--the Higgs signal is much much smaller. I remember something from long ago about the top's mass "leaking," if you will, to the the lighter particles, but that doesn't mesh with how I understand the Higgs mechanism. Anyway, I would expect the Higgs particle manifestation to be the most massive of those that participate in the Higgs field.

North Korea Threatens South Korea Over Christmas Lights 441

K7DAN writes "North Korea warned South Korea on Sunday of 'unexpected consequences' if Seoul displays Christmas lights near the tense border, and vowed to retaliate for what it called 'psychological warfare.' From the article: 'The tree-shaped, 30 metre-high steel structure on Aegibong hill - some 3km (2 miles) from the border - was illuminated by thousands of small light bulbs last year. It could be seen from the North's major city of Kaesong across the border, according to media reports. Pyongyang has previously accused Seoul of using the tree to spread the Christian message to people inside the secular state.'"
