1. If you want to learn rocket science intuition...

Thanks will try that.
2. Typesetting equations with LaTeX: updated

And it seems that one must refresh to see it even when posted. But I like the rendering, and loads of extra gadgets on right click. The hover to zoom is very useful for those of us with imperfect vision

13. Typesetting equations with LaTeX: updated

inline $$y=x^2$$ check $$y=ax^2+bx+c$$ display $x= \frac{-b\ \pm \sqrt{b^2-4ac}}{2a}$ $y = \int f(x) dx$

FFS - How many people in a football team? If I make the question simpler do you understand the idea? So still simplified How many people in the White House Science Office?" Maybe Trump has a point - argue about the phrasing of a question rather than debate the substance - give me strength.

The United States has had more Nobel Laureates in history than any other country (more than top five other countries combined)* - so bearing in mind that incredible heritage ... Question: How many people in the White House Science Office (technically The science division of the White House's Office of Science and Technology Policy (OSTP) ) as of Friday close of business? *including Peace prize and Organizations - I couldn't be bothered to find a list of just real person Science prize winners.
16. Bullet fired from a gun and a bullet dropped descend simultaneously

I am not convinced you and Tar are right there. The sphere is length contracted but very odd things happen when you "look" at it - light (very fast as it is) still has a finite transfer time, and when you are "looking" at something which is moving at a sizeable fraction of the speed of light one must not think of transmission as instantaneous. If I have remembered correctly a sphere being observed will appear to be a sphere rotating (the direction of rotation is as if it is rolling along a floor and we are looking through the floor). The phenomenon is called Penrose-Terrell rotatio
17. Understanding Reality

Brilliant! A plus one on both your Houses Posts. I thought the more prosaic version with word instead of name fitted better.
18. The Allais Effect Solved

I think it is the OP's own website - and yes, I agree with your characterisation
19. Today I Learned

At least for Toyota that might be difficult http://www.toyota-global.com/showroom/emblem/passion/ The old one was really impressive (flying kanji for toyoda)
20. Understanding Reality

- nope but I can see the logic not that - but again can see the thinking
21. Understanding Reality

An on-topic Shakespeare would have to be 23812019,914,1,141135,208120,238938,235,311212,1,1815195,225,11425,15208518,2315184,231521124,191351212,119,19235520 There is a green plus one from me for anyone who can work it out...
22. Viruses, ransoms, trojans, spys and other malware into corporations...

I was just saying in another thread that I think we are reaching peak-online. Not that amount online will fade - but we have reached a situation where it is asked "is it worth putting this online" rather than "can we put this online". The novelty and the thrill of sharing information is wearing off - in situations in which there is a gain to be had then we can go online very easily now and thus there is no advertising premium for being online just for the sake of it. I remember signing up for stuff purely because I thought it was cool to do this or that online. Now, as with smart-phones, compu
23. what is a virtual particle?

There is not much that is forbidden for a virtual particle Here is the good Doctor Matt Strassler https://profmattstrassler.com/articles-and-posts/particle-physics-basics/virtual-particles-what-are-they/ They are "off-shell" and do not have to obey many of the laws that real particles do. https://en.wikipedia.org/wiki/On_shell_and_off_shell Note that Noether's theorem is the mathematical treatment of conservation laws / invariance under transformation
24. [solved... sort of] Trigonometry Problem

No I missed that - but I can imagine. I am no old fogey - but I do think that a fashion in teaching allied to insidious cost cutting has led to a real decline in the methodology of examination. I do not hold with the "everything is getting easier" mantra that is so easy for those of us with pockets full of exams to trot out every August - I think children, young adults, and students in further/higher education work harder (and with less financial) support than I ever did. I think we are at peak-online; we are realising that whilst online access can be world-changing somethings are just
25. Fossils - Finds, purchases, collections

MRI tends to work on the Hydrogen in water and fats within the body. I have no idea whether it would work on stone - it is possible that the variation in stone which we can easily see in fossils is not great enough to create a variation in the nuclear spin transition and relaxation which is picked up in an NMRI scan; on the other hand maybe it does work. Just in case someone approaches you with a chance to do a scan at a cost I would contact your local university's palaeontology dept. first. If you have already done this I would be fascinated to hear response. I know NMRI can be used on ot
