I'm trying to figure out what, exactly, fuses. Magma is composed mostly of silicates ( oxygen, sodium, magnesium, silicon, calcium, potassium and iron ). Of these, assuming you could have a plasma, iron is a dead end for fusion ( no matter how small the atoms get ? ). The lightest element which could fuse, would be oxygen, but, as that requires 1.5 BILLION deg K, I really don't see how it is even being considered in this discussion.

As Swansont already pointed out, That is the incomplete Newtonian model. In the much more ( but still not fully ) complete GR model, it is the ground hitting you, as you innocently travel along a geodesic ( free fall ).

Congratulations ! You have discovered that all motion is relative ( I.e. relativity ) several centuries too late, In a couple of hundred more years, you might realize that our best theory says gravity isn't really a force, but a geometric distortion of space-time.

Don't confuse the arguments I choose to make with what I would like to see for a just society, Phi. Of course I admired Reagan/Thatcher and McCain. I also admired Kennedy, Johnson, Nixon, Carter and Clinton. They all had their bad, and all had some good. ( even D Trump had maybe 1 % good with that whole lot of bad ) And do you see what you are doing ? Your impression of my political beliefs paints me in typical American terminology, "pre neo-con". Try to separate yourself from American political thinking. People are people; they just want what is best for them and the people they care about; if it also happens to benefit others, so much the better. By pigeon holing them as Libs/Cons, or Reps/Dems, or even elites/deplorables, you are assigning your imagined traits to them. America can be 'great again', they simply have to get past this 'us' vs 'them' attitude between two political parties.

So here you ( and others ) are. Your typical news ( available to all )is polarized, either 'left' or 'right'. You have Trump supporting, people on the right complaining that MSNBC and CNN just hate Trump, and have since his inauguration. And you have Trump hating, people on the left claiming FOX news is just a lying mouthpiece of the Republican party. You have a country where 45% of eligible voters will vote Republican, no matter what idiot they run, and another 45% of eligible voters will vote Democrat no matter what the issues. They have always voted that way and will continue to do so; only a small percentage of the electorate, in 'swing' states actually decide who will be President. You have people on either left or right, hating the other side more and more, as politicians ratchet up the rhetoric, and blame everything on the supporting electorate; never themselves. So much so, that political rallies and protests have become dangerous to attend, and people, afraid for their lives, run over others ( or at least, that is the excuse they use ) for the second time now. You guys are neck deep in this sh*t, live it every day, and it colors the way you see, and live, life. Yet two outsiders who have no 'skin in the game', JC and I, often get accused of not being equitable, and being partial to one side. By no means are we trying to compare/equate the two sides, Republican and Democrat, but simply pointing out that neither side are 'angels'. And, I can easily decide which is 'better' for the people, while also recognizing the 'faults' of the 'better' side. While you guys, being so deep in it, either can't see the problems of your side, or choose to ignore it. Not judging, simply presenting my observations.

Ooops ! I still stand by the rest of my opinion expressed in my last post.

Hind sight is 20/20. WHY they were disillusioned with Government ( and H Clinton in particular ) does not really matter. Even if those reasons were not factual, or non-existant, they should have been addressed, and people reassured, not dismissed as complaining deplorables ( there were no qualifiers when she said it, Zap ). I was an H Clinton supporter, and some simple considerations for all citizens may have spared us the last 4 years.

Maybe not important to you, but it certainly was to many people in 2016, who felt that the 'status quo' Government of career politicians, like H Clinton, didn't care about their concerns. D Trump got elected by appealing to those people, by promising to do things differently, and 'draining the swamp' of career politicians and civil servants who were in politics for themselves. The fact that a lot of citizens felt their representative Government wasn't addressing their concerns/needs is literally what disenfranchised means. The denial, or deprivation, of some right or privilege, such as the right to a representative Government. The fact that D Trump turned out to be a jackass, and played those people to suit his own agenda, and has led to even more people becoming disillusioned with politicians, is a different matter altogether.

Sorry I wasn't clear swansont. I was referring to the 2016 election, and why I mentioned to H Clinton, who famously called them "deplorables".

On top of the expert opinions above, I will add my two cents ... The modern picture of a fundamental quantum particle is a point surrounded by a cloud of virtual particles, which grow more and more massive/energetic as you reduce separation. These 'extra' particles add to mass, charge, etc. of fundamental particles, and is their 'effects' that are stripped away in the renormalization of any QFT. A proton is not fundamental, but is composed of quarks, which are; and the quarks are in close proximity. The way Physicist 'dismantle' a proton, is by smashing it at high energies against another particle, and seeing what 'comes out'. High energy protons collisions produce quite a few particles. Even at its lowest energy, a proton is over 98% binding energy; this energy alone is enough to 'produce' a couple of hundred quark/ anti-quark pairs. And there have been scattering experiments done which confirm that a proton acts like a 'bag' full of particles. ( not zillions and zillions )

By 'common folk' I meant people who have become disenfranchised with our political system, career Politicians, and the way government does business. These are the people who, overwhelmingly voted for D Trump, expecting a change, and that he would actually 'drain the swamp'. Boy, were they wrong !

There will always be people who take advantage of other people, so we will always have the TeleEvangelists, the Jim Jones, and the Donald Trumps. Placing the blame with the "people who are not very educated, not very sophisticated thinkers, and too trusting for their own good" is what got H Clinton in trouble and led to the D Trump Presidency. Those people are voters too If the elitist, career politicians who are " very educated, very sophisticated thinkers" would address the needs of common folks, some of whom are not, we wouldn't be in this situation. Government is responsible to ALL of its voters/citizens, no matter how trusting they are.

So... Assume I don't know the area of a rectangle. The computer spits out two sentences. 1 - Bite an apple. 2 - Multiply length time width. I try both. If I don't know what area is, how do I know the area of a rectangle is not an apple with a bite taken out of it ?? If I know that area is length times width already, why would I need to run this idiotic program in the first place ????

Have any of our elderly UK members been vaccinated ? If not could you inform us when you do; we have questions. I don't imagine I'm on any short list to receive the vaccine in Canada, so It'll probably be the summer before I get vaccinated. ( no overseas vacation again, this coming year )

While students can learn many different ways ( being lectured to, reading online or from textbooks, video presentation, etc. ), the part the teacher plays is recognizing the student's interests and developing them. That is why a lot of people have 'special' teachers that they credit with developing their interest in a certain subject, at which they later excelled. My high school Physics teacher was one such educator. He opened his first Gr11 class with the question "Are you moving ?", to which I was the only one who responded "Relative to what ?" The other was a 'tough as nails' Gr13 Algebra teacher who passed away the summer after I finished high school. I had always been a below average math student, but he developed my interest in it by lecturing us at length about things like calculating probabilities of winning the lottery with factorials, or how plants sprout leaves according to the Fibonacci sequence, etc.

I have no clue what you mean by any of this. This is one of the 'assertions' Swansont warned you about. If you don't understand a concept, or are unsure, ask the question; don't go jumping to unsubstantiated conclusions.

But base two ( binary ) and base 16 ( hexadecimal ) are used in computer programming.

No, it seems a lot of people have a choice to make. They either stay home and take care of their own kids, or they send them to the 'de facto babysitting center' so that they can go to work and earn a living to feed, clothe and house their kids, Which would you do ? As for your other concerns, like locker space, excessive paper use, and burning paper/trash in a big bonfire ... What ??? I would think there are many more pressing concerns.

Fraction means expressing as a ratio of two numbers. For example 1/2 = 0.5 and 1/5 =0.2 are numbers between 0 and 1 expressed as fractions, but, you can also have 3/2 = 1.5 and 6/3 = 2 which are not between 0 and 1 . What do you think 'fraction means ? And what is this obsession you have with number system bases. What do you think 'base' means ?

apparently Pfizer vaccines are already being transported to various locations. Canada's are coming from the production site in Puurs, Belgium. I assume we're not getting any from Pfizer's Kalamazoo site, as D Trump has expressed a desire to have Americans inoculated first. Shipments are by plane ( underfloor cargo hold ), in dry ice filled containers, as the mRNA is fragile, and degrades quickly with elevated temps. Special approval has been granted by the FAA for carrying 5 times the allowed amount of dry ice; usually 3000 lbs, now 15000lbs. The sublimating dry ice is allowed to vent to atmosphere, and no special precautions are being taken for pilots, other than warnings about CO2 exposure. Production, and now shipping, has been ongoing even as the vaccine was waiting for testing/approval, so as to have significant quantities available on go ahead.

But this isn't about stopping you; I realize there is nothing we can do. In my city they just spent a couple of million putting up metal catch poles on either side ( and between the two spans ) of a bridge that has been used quite a few times for jumping. Seems kind of useless; instead of jumping from the walkway to one side and off the bridge, you jump the other way in front of a truck. Same result. This is about moral justification for such actions. And I also realise they are going to be different for people with differing morals.

Ahhh, a co-ordinate system for a co-ordinate system. How redundant. I didn't realize bodies were immaterial when not moving. You can pass through the event horizon of a large Black Hole without being torn apart because tidal forces are small. We don't know what happens at the possible singularity, or even if there is one, as our theories are no longer applicable. But nowhere, not even inside the event horizon, is light speed equalled or exceeded by massive bodies.

Damn … I'm not on the list.

The three space dimensions and the time dimension are orthogonal dimensions on a 4D space-time co-ordinate system. IOW, space and time are inextricably linked. What is the geometry that allows for movement through time, and a 'delay' before movement through space ? How do you account for this separation ? Where is the evidence and implications of this delay/separation ? Again what does your equation attempt to explain, and, is there a need for such an explanation ???

I am sorry to hear about your brother-in-law, Zap. I'm sure his passing wasn't easy for your wife or sister, their family, you and your extended family. As I said , It is not something that I'd ever consider, but, I've never been in a situation where I've had to consider it. I don't think anyone should feel that suicide is their only remaining option.
