We are making good progress here, Galu! :D

I have established that Nijinsky won the Epsom Derby that (1970) year, just up the road.

Me and Dad won a packet on the Oaks on "Sleeping Partner" at 20-1 in 1969. TBH, he bankrolled our joint endeavor.

A proud moment since Dad rarely bet on chance. But I fancied that Filly. It was tipped in my Mum's favourite paper "The Daily Mail" by tipster Robin Goodfellow. Which I got after her at breakfast.

I definitely saw something that evening. :cool:
 
I'm reconstructing the day, Galu. Best as I can. Then the truth will tell...

I have further learned that my two favourite Soccer teams of the time played on the 10/04/1970 Friday Night before Apollo 13 launched.

Teh Sky Blues (Coventry City) beat the Wolverhampton Wanderers 1-0 on their way to their finest finishing position in League 1 of 6th.

I was probably delirious with excitement. :eek:
 
Google is amazing. I am making great progress! :D

Turns out I was looking South-West into the evening twilight.

I was looking straight out of the back window from the second house in Talisman Way, Epsom:

Google Maps

About 15-20 degrees above the horizon, IIRC. So I might have been looking out to the mid-Atlantic. Saw the boosters fire. And nobody likes boosters more than I do at 9m21s: YouTube

Altitude perhaps 500 miles, if I haven't lost my touch.

Just a splendid gratuitous link! :eek:

Now we move onto launch time:

Apollo 13 - Wikipedia

2.13 EST. I get confused about this stuff even with Gridiron kick-off times. Perhaps our US Cousins can help?

We are 5 hours ahead the US IIRC. Er, so 2.13 EST launch is er, 19.13 GMT. So I reckon this must have happened about 8 in the evening in Dear Old Blighty. On the first orbit after launch. So must have been about half an hour after launch. :)
 
Aha! I think we are talking about losing the second stage rocket here, and firing the third stage for orbital insertion, creating a fog of smoke behind the spacecraft.

Apollo 13 Timeline

19.22 GMT I think. I would have known what I was looking at here in the twilight. I wouldn't have been fooled by a planet or aeroplane or star. It is conceivable that I watched it two hours later on the second burn though. Long time ago.

This ramble all started with the question about astronaut Jim Lovell in the Telegraph pub quiz on July 4th. :)

"Who is the only Astronaut to have gone to the Moon twice without landing?"

I have to admit that 50 years ago is a long time.

According to latest ideas in Quantum Theory, not only is the Future uncertain, but so is the Past. :confused:

Whatever. I was once in a bar in London. I asked my stranger/friend at the table what he did for a living, like you do. Because London is quite friendly to strangers.

Told me he was a "Rocket Scientist"! :D

I was impressed. Rocket Science is quite hard, IIRC. Beats all that " 'Ow did Chelsea get on last Night?" stuff. Never mind the "Eff off" and "See ya later" stuff that the provincials seem to specialise in before falling over in the street. :eek:
 
The discussions seem to be making no progress...

According to latest ideas in Quantum Theory, not only is the Future uncertain, but so is the Past.

Determinism is not dead, it cannot be abolished. Determinism, which has its roots in religion and belief, states that every event is causally necessitated by preceding events, so a cause preceding effect in time predicts the future. In mathematical logic everything, including time, is symmetrical. By the symmetric directionality of time, the past determines the future and the future determines the past.

As Einstein said, stupidity in science knows no bounds.
 
Lord knows, I have signed this piece of nonsense enough times in my life:

We just do it for the bucks. :D

Nevertheless, as a man of considerable UK Defense employment, I am wary of telling you about the holes in our Missile defenses versus the Bad Guys. But we shall win. :cool:

What is more interesting, IMO, is that the UK is currently abandoning sound Monetary Policy in favour of subsidising Eating Out. This is SO 1970's.

I suspect it will end in tears. :eek:
 
OK, I said that.

In fact, the redshift in light is not directly comparable to the Doppler effect in sound. The physics is different in each case.

What would the physical difference consist in?

The speed of light is invariant no matter what an observer does.

According to Einstein's theory of general Relativity, which is not a physical theory but a mathematical hodgepodge, the speed of light is Absolute. Unfortunately, he did not explain how can something be both absolute and relative, both invariant and shifting at the same time. Absoluteness is so much easier to deal with mentally.
