  2. Not today, but recently I learned why some mummies look like screaming. After some post on FB from a friend of mine about the Phaleron mass grave. An archaelogist wrote: I just wanted to make a small comment, with regards to the jaws and postmortem opening, from a biological perspective. Since mandibles are attached to the skulls by joints and two muscle types (masseter and pterygoid), after death, these parts are lost, so mandible drops and gives that "terrified" look.

  3. 1. You are presupposing that the reality is "a loaf of bread". 2. In your example, the loaf of bread xists only when you cut it. Before cutting, there is no loaf, there is the entire bread. 3. The loaf & the bread are static things. Our world is dynamic. What I say that if you put a pen on your desk, this pen is what it is, it is a 3D object. It is not a 4D entity that stretches into the past. There is no bread of pen, and your pen is not a loaf cut from something bigger.

  5. That is my point. The conclusion that I draw from this is that the different positions in time are mutually exclusive. That is to say that if you are at T1, you are not at T2, T3, etc. And if you are at T3, you are not at T1. Which means that a 3D object remains always a 3D object. It does not become a 4D object. All objects are 3D objects that travel through time, being only once at each time stamp T and never occupying more than one time stamp "at a time".
  6. a. Can one object be at 2 different points of space ? The answer is Yes it can, but not at the same time. Meaning that the same object A can be at point 1 at time stamp T1 and at point 2 at time stamp 2. It cannot be at 2 different points 1 & 2 at the same time. That was for Space. Now the new question: b. Can an object be at 2 different points of time ? The answer is Yes it can. But not at the same time The underlined condition looks like a tautology. Of course an object cannot be at 2 different points of Time "at the same time". Which means that IF an object is at time stamp T1, it cannot be "at the same time" at time stamp T2. Or, because the "at the same time" is tautologic when speaking about Time, what one could say is the following: If an object is at time stamp T1, it is not at time stamp 2. And if the object is at time stamp T2, it is not at time stamp T1. IOW time stamps are mutually exclusive. Is anything wrong in the above?
  7. Good point. After college for meeting people you may pay for it (like Rotary & Lions club, tennis clubs, gyms, dance schools & many other ways). Not to say that the choice of College is very (very) important.
  8. Be careful. There is a trend lately that want people to believe that there is no need for studying (examples from successful teenagers entrepreneurs). It is a trap. Made by people who want you to become an imbecile. It is not difficult to understand why. Except if you belong to that same category already. I was not listening then. I am very bad at giving advice. And would you listen?

  11. This site (in French & English) has published (open source) 18000 pages of mathematician Alexander Grothendieck archives, out of the 28000. (copyright issues) For those interested (and who can understand) https://grothendieck.umontpellier.fr/archives-grothendieck/
