Hello people. I'm actually a humanities scholar but who has retained his interest in maths from high school.
Well curiously, in relation to one of my projects I'm investigating the properties of third order Beziers. Given the two nodes and control points of a third order Bezier, I needed to...
Hello people. It seems there is some misunderstanding possibly due to the wording I used in my remembering of the quote. As I noted, it was not verbatim.
Obviously experiments which were done previously will not suddenly stop to work.
What I meant by "flawed" (which is quite possible not the...
Back when I was in high school I had this chapter on Albert Einstein. I remember reading something to the following effect:
Can anyone confirm/deny whether Einstein said anything like this? (I mean is there something like "Collected works of Einstein" as there is for other philosophers?)...
Hello. Can anyone please provide me with an authoritative definition of planetary precession? Any link to an authoritative source would be best. I did do my googling first. I tried to provide my search results but an ostensibly spam-blocking feature does not allow me to post the links because I...
For the sun and moon I will be using the JPL and VSOP/ELP (the latter for the users who do not have the JPL files). For Spica of course I have ICRS coordinates and proper motion from Simbad.
Now I am wondering which of these various corrections can be neglected because I do not require a...
I need geocentric positions for Spica, sun and moon from 1800 to 2200 (or so) to the nearest tenth of an arc-second. "What data I am working from" -- I do not understand this.
Hello and thanks for replying. I need geocentric apparent positions of the sun, moon and planets to the nearest tenth of an arc-second. So please indicate which corrections of the seven listed I can drop. Thank you.
I would like to calculate with high-accuracy the apparent geocentric positions of this three: Spica, the sun and moon. I will apply the following corrections for Spica:
1. proper motion
2. precession
3. rotation of ecliptic
4. stellar aberration
5. annual parallax
6. gravitational...
