Science is looking up

Went to a talk by Arno Penzias back in the late 80s.

He was describing the annoying "hum" that his experimental antenna was picking-up. (not really a hum, cause not audible)
They thought it may have been caused by birds doing their thing on the antenna.
These scientists were applied physics - but he got into a discussion with a theoretical physicist.
When Penzias revealed the frequency of the hum, his fellow scientist recognized it as matching one of Einstein's predictions.

Einstein couldn't prove it - so he fudged all his equations with something he called the cosmological constant - and there it was.

The antenna and site are going to be preserved - down in south jersey.

rocket science.

satellites like directv are in geosynchronous orbit. They are always in the same spot over the earth -
so an antenna can be pointed at them.

This is cool - solarsyncronous - they appear in the same place relative to the sun in relationship to the earth (solar time of day) each day


Sirius satellites use a polar orbit, but are not synchronized - they are polar orbits that project their path over north america as the earth rotates.

XM satellites are like DTV, and use ground repeaters for coverage (or lack of)

now you know.

Meteor shower tonight out of Ursa Minor (little dipper/north star)
 
more meteors tonight -

and rocket launch is on out of VA ~6pm. scattered clouds now, but looks to be clearing.

this was a smaller rocket than the last couple times - just a little red blip that disappeared into the clouds.
 
There is(was?) one on Mountain Ave in Murray Hill - Bell Labs used it - which is where a lot of the formal definitions around sound/hearing came from.
I spent my summers at Bell Labs in the mid 80s and knew it was there. Didn't see it in person but saw early optical cables being made.

My Dad worked there in the 70s. I remember going to an open house at the labs and going into this room.It was so wierd, there was no echo.

I remember talking on one of the first picture phones.The only thing stopping it going public was the lack of bandwidth they had.

Were you a young pioneer, or intern?
I was in MH from 1987 until they kicked us out - then we went to Florham Park - they were building the Jets facility at the time.
