On Crawford Hill in Holmdel, New Jersey there's a collection of old scientific radio antennae which were built decades ago but are now abandoned. One of these is a Hogg Horn Antenna built for project Echo, the first proper demonstration of realtime satellite communication. It needed to be large and exceptionally sensitive because the satellite was a passive reflector rather than an active relay.
This sensitivity later lead to it being used as a scientific instrument to study the skies in radio waves, but the scientists using it, Arno Penzias and Robert Wilson struggled to eliminate radio noise which was creeping in. They worked hard to get rid of this until they eventually discovered a scientific explanation for this and ultimately were credited for their work in discovering the cosmic microwave background radiation.
The site is currently abandoned, but the horn antenna is registered as a historic place, hopefully this will result in the preservation of the antenna for future generations.

Scott, Thanks for this video. I had the pleasure of working at Crawford Hill in the mid-80s with Bob Wilson as my assistant director. Instead of climbing the management ladder at Bell Labs, he preferred to keep his hand directly in R&D. In addition to managing various wireless communication projects, he and Greq Wright pursued molecular astrophysics in the multi-GHz range using the second off-axis parabolic antenna which you showed. They also worked with a group that setup a small radio telescope at the south polar station (very high and dry) to look at OH molecular clouds. Bob was a great guy to work with, full of ideas, very inquisitive and supportive. Sorry to see the facility in such a sad state of decay. Working there was a highlight in my career. Eric Sweetman

I visited this place about ten years ago. The road was blocked by a gate which had a No Admission sign on it. There were lights on in a building nearby so I went into what seemed to be a reception area to find someone to ask if it would be OK to go up and look at the horn. I rang a bell at the desk and waited for several minutes, but no-one appeared. As there wasn’t a fence attached to the gate, I just walked past it and up the hill to find the antenna. It looked to be in slightly better condition than in your video, and it was a real thrill to reach up and touch the end of the horn that made such an epic discovery. It's a terrible shame that such an important place is being so neglected, especially since there’s a plaque saying it has been designated a National Historic Landmark. Many other less significant sites have a visitor centre and a gift shop: why not this one?

@robertbutsch1802 2 года назад

This is actually one of the strangest and most fascinating stories in science. Penzias’s and Wison’s day job was evaluation of the horn for use in the Telstar communications satellite project. It was in this capacity that they saw the nuisance unexplainable noise. They didn’t know about CMB predictions by Dicke and his group, or about scientists in the Soviet Union who had rediscovered the much earlier work of Gamow and his group where the mathematical prediction of the CMB was buried in the details. The Dicke group in turn didn’t know about Gamow’s work. The Soviet scientists did think that the Holmdel horn was probably the best radio telescope in the world to try to detect the CMB but weren’t in a position to do anything about it. Dicke and his colleagues didn’t know about the Holmdel horn, only about thirty miles away from them and carried on trying to develop an instrument to detect the CMB. The situation was described by Timothy Ferris in his excellent “The Red Limit” as “...a perfect tripod of ignorance.” Eventually Bernard Burke, who knew of the Dicke group’s work and of Penzias’s and Wilson’s noise problems, put two and two together and suggested that Dicke and Penzias and Wison ought to maybe get together and compare notes.

@mechtheist 2 года назад

That story has long fascinated me also, back to when attended a lecture by Penzias in the late 70's. Much later, when I read about Gamow et al's work and that of Dicke's group, it kinda puzzled me about the weird way the Nobel Committee operates. P&W basically fell into their discovery by accident, they did good work eliminating terrestrial origin, but that's hardly groundbreaking, they didn't figure out what was happening, they learned it from Dicke and all of them were way later then Gamow, Alpher, and Herman. BUT, they can only give the prize to a maximum of 3 individuals, which sucks for situations like this.

@jeffk8019 2 года назад

@@mechtheist Yes this is a fascinating story and I've also been interested in it for years. As the story goes, when P&W figured out what they might be measuring and found out about Dicke's group, they called Dicke who at the time was in his office with other scientists deciding their next steps in detecting the CMB. When Dicke got off the phone, he somewhat calmly told the scientists something like "well boys, we've just been scooped". That must have sucked. Yeah, how the Nobel is awarded is unfair in many cases.

Interesting about the Telstar satellite! My father used to work as a Sound Engineer for the BBC here in the UK. He was part of the team that received the signal from Telstar, as it crossed over the Atlantic, and from that split into the audio (his part) and video for broadcasting. I still have, somewhere (!), pictures of the test signals that were 'beamed' across. These would have been the very first television pictures broadcast from the USA to the UK and Europe. I believe he worked out of Goonhilly Down in Cornwall in the UK.

My father was a business accountant who bought antiques at flea markets as a hobby, then later as a business when he retired from accounting. Somewhere around ten years ago, he was selling at a market near the border of NJ and PA, when a guy came up to his table, and they got involved in a conversation. Somehow it came up that he had worked at Bell Labs a while back, and got a Nobel Prize for work on cosmic background radiation. My father had no clue about any of this, but when he relayed the conversation to me, I knew exactly what it was about, and that there were only two people it could be. I showed him pictures of Wilson and Penzias, and it turned out to be the latter. So Nobel-winning physicists like to bum around flea markets just like the rest of us.

The first patent for a transistor similar to today's field-effect transistor was filed by the physicist Julius Edgar Lilienfeld in Germany in 1928. At that time, however, materials research had not yet progressed to the point where this transistor could be built. The theoretical principles were devised by Walter Schottky, an engineer employed by Siemens at the time. Oskar Heil (the inventor of the klystron) applied for a patent in 1934 in which he proposed capacitively acting control electrodes on semiconductors, known today as field-effect transistors. Transistor research in Europe and America was interrupted by the Second World War.

I got to shake his hand. It was inspiring to meet a Nobel winner as a kid. So great to see a shout out to home, keep up the great content!

Penzias’ and Wilson’s paper does mention removing the pigeons and cleaning a “white dielectric substance” from the inside of the antenna. I guess “pigeon poop” doesn’t sound Nobel worthy. ;-)

While you are in NJ you should also check out the Trios Dish in Wall township. It was built by the army to communicate with the trios weather satellite (although it was probably an early spy satelite) the dish was built in the 1950's but recently restored by Princeton University to use for their own radio astronomy work. The satellite is owned by a small science technology museum so if you ask nicely they can show you around.

It’s just one small part of a large collection of vintage/antique science that I’ve been blessed to curate. Preserving and sharing antique technology with others is one of my greatest joys and passions. It’s an incredible shame that this historic site is not being properly preserved.

8:32 The Planck telescope satellite doesn't come close to measuring 4GHz (~74mm wavelength). It's lowest resolving frequency is 30GHz (~10mm). It found the peak of the CMBR to be at 160.2GHz (~1.8mm). Just to clarify, the article you flashed up by Pierre Robataille just following is saying the Planck data does NOT show a (ideal) 3K/4K blackbody emission spectra? Even with the large measurement error bars, the ideal curve does seem to deviate...

@Azmodon 2 года назад

"The Planck telescope satellite doesn't come close to measuring 4GHz". He didn't say the planck is what measured it at 4, just that the first measurement in 1961 did. The measurements are as close to perfect as one could hope, with no outliers. Planck only confirmed what COBE had measured a decade earlier, COBE being at 900km, while planck was out at 400K km.

@@scottmanley Actually, you did not highlight any error on my part. The CMB monopole (Penzias and Wilson signal) has never been measured at L2. This is contrary to your claim that it has been measured millions of miles from Earth. If you believe that the monopole has been measured there, please send me the papers. You will search for a long time, as I know the literature in this area. The problem is that the cosmologists themselves are not being forthright with the general public and they never highlight that they have not measured the monopole at L2. There anisotropy maps are nothing but playing with noise as I have correctly highlighted in my video series on the CMB.

@robertmandell526 2 года назад

What's far worse than the abandonment of some hardware (after all it's just hardware that could be easily reconstituted), is the dissolution of Bell Laboratories, AT&T's Pride and Joy World Famous Research and Development institution. Penzias and Wilson were just TWO of the Nobel Laureates at Bell Labs. There were at least FIVE others including Shockley, Brittain, and Bardeen (inventors of the transistor--in fact Bardeen won TWO Nobel Prizes). And there was Avi Meyer, inventor of the laser "tweezer" used extensively in quantum electrodynamic studies; and on and on with thousands of groundbreaking devices and concepts. Ma Bell should have donated Bell Labs to a university consortium, so that its seminal work could continue into the future--after MA Bell was broken up, faced real competition, and decided a Mega Research Jewel was too, too costly to carry! So sad!

@LemonLadyRecords 2 года назад

It was legendary even when I was a kid, in the 50s. On a positive note, cheap phone services, affordable long distance calling, and many telecom developments, resulted from the Bell breakup, fair competition and deregulation, but Bell Labs should have continued to have been funded at the same level. Under Ma Bell, phone service was a nightmare and long distance, even within the same county, was so expensive we timed and rationed it to Sunday nights only. If you got a LD call during the week, you thought someone had died!

@1pcfred 2 года назад

Bratton and Bardeen were both living in my home town when they made the discovery up at the Labs. Shockley lived in Manhattan. He wasn't even really working on the project when the breakthrough happened. Scott mentions UNIX briefly and Dennis Ritchie grew up in my home town too. He's the R in K & R C. When I was in grammar school the geeks from the labs put on an assembly for my school about lasers. It was hilarious. That whole place was an insane asylum.

@robertmandell526 2 года назад

The term "Unix" was Kernighan and Ritchie's play on the popularity of the Multics language at the time. The K&R definition of Unix led directly into the BSD (Berkeley Standard Definition) version of Unix at University of California Berkeley. I was at Berkeley while it was in development. And Unix/BSD lives on! It's the essential superstructure upon which Google built Android, the ubiquitous operating system on most cell phones

@1pcfred 2 года назад

@@robertmandell526 Google built Android with Linux. Which is a UNIX-alike OS. Linux shares no code with UNIX though. I think years ago Linux used a bit of BSD code in the user space? But that was all replaced. Linux is a free implementation of Minix. Apple uses BSD for their OS. That's because the BSD license allows you to close the source code. BSD is not GPL. Why UNIX ended up at Berkeley was because of monopoly laws. The government decided a phone company shouldn't be in the OS business.
