In other words, the higgs mechanism contributes directly to the stress-energy of the particle - did I understand correctly?
If so, allow me to refine my understanding with another question. In the higgs model, does the contribution to the inertial mass and the contribution to the...
If we explain the origin of inertial mass with the Higgs mechanism, how do we explain the origin of gravitational mass? In other words, how does the Higgs mechanism contribute to the gravitational field of a particle?
(Note: the closest thread I've found to this is...
Since ancient times our species has always looked toward the sky. For that reason I find it hard to believe we will cease our attempts to build ever higher. However, we may do both. In any case, this is a philosophical discussion which is not the concern of this thread. If you wish to pursue it...
Hmm... forgot about bedrock.. I suppose with a deep enough foundation that can be resolved. Of course, one would also need the technology to build that deep. and I guess you'd have to count the foundation depth as part of the total structure height as far as structural integrity is concerned. So...
Yes, I've thought of the space elevator as well. But I would like to focus more on the skyscraper problem (sorry if it wasn't highlighted enough). I would think that the problems for a skyscraper would be different, since it is not suspended and hence doesn't gain as much from centrifugal...
Suppose we had the technology to produce artificial diamond beams and carbon nanotube rope cheaply enough to use in large quantities. If we use the diamond for compressive load, and the CNT ropes for tensile load, how tall a skyscraper could we build using these materials, in theory? Is there...
Yes, if the matter and antimatter were close together, they would sooner or later annihilate, and we would expect to see the associated energy release. But would it not be reasonable to assume that where such events could occur, they have already occurred, for the most part, a long time ago...
In my thread regarding the telescopic detection of antimatter, it was concluded that we cannot discern anti-matter from matter when observing it via telescope. As a follow-up, I have another question - or rather a few tightly connected questions:
If we cannot tell the difference when looking at...
Hello, assuming we can detect antimatter with some telescopic technique just like we can detect matter, is there any way to tell them apart? How would this be done?
This is a hypothetical question that I am curious about..
Suppose we are trying to design a projectile that is intended to travel at high hypersonic velocities, on the order of mach 10 or 20, through air (you can assume sea-level density for argument's sake).
Would an ideally sharp round...
Hello, I was wondering if there are any exothermic (or otherwise spontaneous) chemical reactions that release hydrogen, in which the reagents and products aren't strongly hazardous?
I know of the reaction of alkali metals with water, but these produce strong alkaline solutions.. Perhaps one...
In hebrew there is a separate word for the part where the wave goes around an obstacle, and another word for the part where two waves combine and either add up or cancel each other. When I say "diffraction", I mean the former (going around obstacles), and when I say "interference" I mean the...
There's also a difference between monochromacity and coherence. Monochromacity is when the light is all the same wavelength. Coherence is when it is all in the same phase. A laser has both of these qualites, whereas typical white light (e.g. from a lightbulb) has neither. And when I said one...
Yea, you may be able to see some diffraction (as in light going around your fingers), but if I'm not mistaken you won't see any interference (as in light adding up constructively and destructively to form those familiar patterns). AFAIK you'll need a coherent beam such as a laser to see the...
Ok, thanks for the suggestions - keep 'em coming. :smile: Btw, anyone tried to fill the area between the slits and wall with steam to see the diffraction pattern form along the way? And just a safety note for that - the scattered light would be weak enough to be harmless, right? Or would I need...
