It is just fvcking amazing. The self-styled physicists have fvcked up
on modern science, and now they are also psychology profilers. Don’t
tell Koobee Wublee that the self-styled physicists were a bunch of
psychology majors as undergrads. On the other hand, it might explain
why the self-styled physicists have intelligence border-lining with
vegetables. <shrug>
For example, the self-styled physicists have bragged about the GPS
being a hotbed of verification for GR. Well, in reality, it is far
from the case. The clock, the frequency accumulating the calendar
time, will certainly drift over time, temperature, stress, radiation,
reflection, refraction, and other engineering concerns, and it is
crucial to understand what exactly have to be synchronized. <shrug>

When all these unwelcomed effects are added all up, the anomaly will
certainly be larger than the puny effect GR predicts. That is why
engineers, the PROFESSIONALS retired or not, have devised algorithms
to overcome this issue such as the IEEE1588 to overcome these
anomalies whether if GR effect is valid or not. <shrug>
http://en.wikipedia.org/wiki/IEEE_1588
Below is play between Tom and such a GPS satellite educating the folks
how clever engineering solutions can simply be achieved to overcome
these challenges where GR effect even if exists represents a very tiny
portion. Self-styled physicists have no right to claim the GPS for
their glories/trophies. <shrug>
Satellite: Tom, every 24 hours, just send me the UTC time, and I will
adjust my calendar time to match the UTC time.
Tom: Oh, don’t bother. You need GR for that.
Satellite: No, not really. Please just do what I have asked you.
Tom: OK, that would be a waste of time. How would you meet the
specification of setting your calendar time to within 1 usec of the
UTC time?
Satellite: My clock is 100MHz. This gives me a resolution of 10
nsec. It should be a piece of cake.
Tom: OK, at the time of beep, the UTC time will be
2,000,000,000.000’000 sec.
Satellite: Thank you. Please beep me again in exactly 24 hours of
your time from that beep.
[24 hours have passed in uncle Tom’s cabin]
Tom: Hey, Satellite, are you still there?
Satellite: Where the devil have you been? You are late. I have been
waiting for you beep for quite some time. My time has registered more
than 24 hours since your last beep.
Tom: No, I am not late. I had a restless sleep last night in which I
kept dreaming about Koobee Wublee haunting me everywhere I go. Among
our discussions, He beats me hands down in every subject. I am so
scared of noticing a post from Koobee Wublee addressing me. Oh, God!
I am going insane. What I have believed in the past is totally
bullshit according to Koobee Wublee, and a large part of me agrees
with Him. <weeping>
Satellite: Calm down, Tom. You are about to come up with the 24-hour
beep. Please stay in focus.
Tom: Oh, yes! At the time of beep, the UTC time will be
2,000,086,400.000’000 sec. <more weeping>
Satellite: Thanks, Tom. I don’t need you anymore. Now, I have all
the information I need to lock my calendar time to the UTC time
accurately to 1 usec. Well, this is an ideal situation.
Realistically, it will take several iterations to achieve just that.
Tom: <wiping away his tears> Wait! You need GR for that.
Satellite: Your 24 hours ago, when I first received that beep, my
calendar time showed 1,428,376,019.877’255’03 usec. 24 hours late, my
calendar time showed 1,428,465,254.688’912’73 sec at the time of
beep. In conjunction to...
Tom: <cutting Satellite off> You still need GR for that. <pounding
his shoe on his desk>
Satellite: No, I don’t. From the information I have gathered, I know
my 24 hours is (1,428,465,254.688’912’73 - 1,428,376,019.877’’25503 =
89,234.811’657’70) sec to yours (86,400.000’000 sec) which means my
clock is ticking (89,234.811’657’70 / 86,400.000’000 = 1.0328’103’201)
times too fast. I can easily compensate for that through software by
subtracting (89,234.811’657’70 - 86,400.000’000 = 2,834. 811’657’70)
sec every 89,234.811’657’70 sec. Also from the last beep, I know I
need to add (2,000,086,400.000’000 - 1,428,465,254.688’912’73 =
571,621,145.311’087’27) to my own calendar time to match with the UTC
time.
Tom: You are an idiot. You still need GR for that.
Satellite: I have just demonstrated that you do not need GR to match
my calendar time to within 1 usec of the UTC time, and my clock does
not even have to be the same as yours.
Tom: You are still an idiot. You will never learn. There is no need
for me to communicate with you any further. <more raucous ranting>
Satellite: <shrug> Once again, science triumphs over mysticisms.
Dr. Jekyll within Tom: Save me! Please, save me from the bullshit
the self-styled physicists are feeding us (me and Mr. Hyde).
Mr. Hyde within Tom: No, you don’t. Mysticism always rules within SR
and GR. <shrug>
