I Read tfa earlier and then a bunch more about it. It mentions something about metallic hydrogen forming a lattice similar to those in iron or steel and would indeed remain a shiny metal. There was mention also of it being useful as a room-temperature superconductor and later i found that metallic hydrogen may also be a great rocket fuel with a specific impulse of around 1700 seconds!

I'm not a physicist (oops - i mean IANAP) so the standard dose of salt should apply but i have watched many lectures online about many topics within physics. My understanding is that it really is the same term but used a bit differently.
Einstein favoured a steady state term(iirc he used gamma for it) in the equations for GR which was called the cosmological constant. Along came hubble who discovered the expansion of the universe and Einstein finally gave up on the fudge-factor term he had inserted to keep the universe mostly static..
60 or so years go by until scientists in the mid 90's discover that the expansion of the universe is accelerating contrary to most of their expectations. They reinstate the fudge-factor term but this time to represent so-called dark energy and it's effects on space-time.
That pretty much brings it up to date. For more info find Susskind lectures on all kinds of physics on youtube and on the Stanford site with a few honourable mentions in the repository of the Perimeter Institute's public lectures available at their site.
Stormtrooper Precision Quotient, or PQ, is quite low. Untrained civilians would hit their target by chance far more often than stormtroopers seem to.
A good kitchen squad may come out with a PQ approaching 1 but the other place down the street that messes up food orders all the time rates closer to.7 - every third time there's an error with the meal.
Civilians doing the stormtroopers' jobs would likely have a PQ of close to.05 or so in combat situations and i would rate the stormtroopers closer to.03.
Even when sent through the slits one at a time the electrons interfere with themselves and the full interferance pattern will emerge over time. The pattern vanishes when using a detector to determine which of the two slits the particle goes through. This is one of the factors that confirms wave-particle duality in the framework of Quantum Mechanics. It's also currently a 1st year physics lab for University students at many institutions.
They throw out hundreds or thousands of collisions for each datum they keep. So they have billions of events stored as data out of many trillions of mostly-boring collisions so far. This cherry-picked data may have something to do with it.
Hawking thought this when he discovered/derived Hawking radiation from black holes. "Virtual" particles popping into existance exactly at the event horizon. Rather than annihilating as such particles typically do, one falls in and the other is released from the black hole.
This is a somewhat simplified account but the realization of virtual particles has been "known" for a few decades. Search youtube for "Susskind Black Hole" for a lecture series, about 16ish hours of material on this phenomenon.
returns useful results. That's close to the term the popular media ascribed to the phenomenon when it was discovered and is close enough to the terminology in the journals to find the scientific papers involved without much extra effort.
Your call as to what you would like to call it though.
They found something that looks like a higgs, smells like a higgs, and even quacks like a higgs while looking in the higgs-pond. They, afaict, have not yet measured its quantum-spin as being zero which would confirm it's indeed a higgs.
If the higgs-like object that was discovered is truly A higgs, it may or may not be THE higgs of the standard model. The newly discovered decay channel of the higgs-like object seems to point toward the standard model and a few other frameworks which others here know in far greater detail than I.
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.

Bobba is close to .9999 or so on this scale btw.

In one of Susskind's lectures he refers to EPR where R = 1. I don't recall in which of the hundred or so lectures I have watched he says it though.

To be fair the extra couple of lines of code may have caused keyboard lag on early IOS devices like my iPod touch 3g. A capable device it was not!
My later iPod touch 4g could probably have handled it but then but then they would have had different devices exhibiting different behavior.

IIRC most of mass comes from quantum electrodynamical interactions. About 5 per cent is due to Higgs field interactions.
Google: "youtube susskind higgs" for some lectures on higgs interactions and some implications of them. One of them is my source for this.

640 kg in, say, 640 1kg dirty bombs wouldn't need to be nuclear, only radioactive. Might be enough to "dirty-up" a whole lot of china's land.

This is an interesting development. Thanks for the links.
We could call it whatever we like but "higgsoid object"
www.google.com/search?q=higgsoid+object&client=ms-opera-mini-iphone&channel=new&gws_rd=cr&hl=en&sa=X&&as_q&nfpr=1&spell
has no search results whereas "higgs-like object"
www.google.com/m?q=higgs-like+object&client=ms-opera-mini-iphone&channel=new
returns useful results. That's close to the term the popular media ascribed to the phenomenon when it was discovered and is close enough to the terminology in the journals to find the scientific papers involved without much extra effort.

Undergrad so take this with a grain of salt.

Now they need to measure the spin...

Undergrad here. So the base case is taken care of and you call your translation function recursively. What's the difficulty here?
