 Dec 11 comment When it is said that the Higgs field is a scalar, do they mean Lorentz scalar? @Adam thanks! Sorry, what are those 4 components of Higgs you said about?

Nov 30 comment 2.45 GHz Microwave oven and Wi-Fi Power matters. WiFi has very low power. But if you take off plastic "peel" from WiFi antenna and nake the metal, you can burn your skin from it. Nov 30 answered Spring force vs Spring Potential Energy? Nov 20 comment Possibility for contact lenses that enhance the vibrancy of color I guess non-linear optics without a power will be limited, because it should use the power of incoming light, which may be insufficient for given algorithm. For example, suppose we want just to increase luminosity in uniform way. Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? My text is self-containing. I don't claim my measure is correct, I just describe how I did it. Moreover, I can predict, that my form of measure will prevail in future, when interstellar travels arise. Because it is natural to measure distance relative to always "stationary" ground. Later, the measure relative to microwave background will arise (when intergalactic travel) :) Both will show superluminal speeds sometimes. Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? Sorry, didn't understand about ducks, I am not fluent English. Nevertheless, mileposts can show faster-than-light speed. Read my comment to original question. Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? Ah yes, sorry you are right at this point. But don't think this is what was asked. Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? Hint: don't jump from one reference frame to another unexpectedly. First select most simple reference frame, then calculate task it it, then transform to another reference frame correctly. The fact is: in principle, pilot can reach Alpha Centauri for one second of personal time. This means, that his impression can be that he moved at a speed of 4 ly per second -- much faster than light. But this is not what is regarded as physical speed. Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? @dmckee P.S. I am aware of relativity Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? There would be no velocity summing by Universe. From the point of view of pilot, he will be stationary. But he will feel G-force. Assuming it is 10m/s^2, pilot can sum this value each second and at some time will get a value greater than C. Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? Your plot describes situation from the point of view of stationary observer. The question as I understood it, asks about the impressions of a pilot. Pilot will feel $g=9.8\approx10 m/s^2$ all the time. This implies, that after 300000000/10/60/60/24 = 347 days he will come to conclusion, that he is superluminal. Of course he will be wrong, but the question is about impressions. Nov 19 comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light? What to calculate? What are you doubt in? That summing of 10 will supersede 300000000 after some number of operations?
