It wasn't that they were mining in a mountain. They were mining from Roots of a tree. That whole book is about petrifying trees and harvesting the metals from them. It's infuriating because you can see the scars and marks all over our earthly plane. The use of a fresnel lens.. It really upsets me because there's an Apocrypha for missing from the book. It makes me mad that all information is not at our fingertips. And this time, I did not have the pleasure of having a higher education at MIT or Johns Hopkins.. Harvard Princeton Dartmouth.. really upsets me. Aaron Schwartz is a total hero in my book. I don't think he ever took his life.. It's part of manipulation of history. Part of hiding technology they don't want us to know about. And literally deforesting are beautiful wonderful world. Terraforming it. Which they do to this very day.. Strategically burning down cities. Patent offices moved years or even just a few months before the great fires. And history is not the wiser. Some of us are.

Thanks, great talk.

The whole cold war was just to cover up ionosphere research lol

I was disappointed with the presentation. Typical example of a person who knows a lot, but the teaching style is to go through the material facts and just name them one after the other and not really explaining anything or very little. Like a review for the same people that already know it all, just to remind them.

I don't think the Soviet union was too happy with that ship broadcasting the Voice of America.

Kristina Collins is hott. id like the handout as well.

Can't play the sounds. They have copy writed this pattern in sound. Exactly why I hate all america for sure. Thats like the idians trying to tell the british to get off their land. Were we like ohhhh ok. Youre right that land was copy writed? hell no. Play that music. They can go sit on a stick a dynamite, they already made their money. We are the USA and well, the USA copyright bullshit is the indians - bound to lose over time for it is manifest destiny that that sound will be played loud and FREE for all to hear like a fart echoing around the grand canyon.

"This is what you call an rtl dongle. eight bucks on ebay." --- This is exactly how adversarial malware is spread sneaker net style right through our most important institutions. I hope he doesn't do any work for our Gov't.

knowledge is truly power

Great lecture, but those soy boys in the beginning😝

6:19, 43:50 37

Speech dwindles into monotonous mumbling.

WOW!

Great lecture. Lots of good data and analysis. The FM band has the most powerful signals in the spectrum by a large margin. When FM was introduced all receivers used vacuum tubes so the transmitters had to be extremely powerful to get the audio frequency response and quieting effect. Today's receivers are orders of magnitude more sensitive, but the broadcast industry is entrenched, and it will take a digital revolution to change things, as it did with terrestrial television.

I really enjoyed the video! However, I believe that there is a factual error. The speaker said that Multics was the first O/S written in a high level language, but I believe that it was preceded by the O/S of the Burroughs B5000, which was written in a dialect of ALGOL.

People in the live audience should keep their questions til the end, actually it mostly sounds like the same man all through this series, always interrupting with questions. Particularly in these days of powerpoint, but even in the days of analog slide-shows, not many speakers can deal adroitly with digressions.

Thank you! This excellent video taught me a lot about HF Propagation. As a result, I shared my knowledge of this fascinating subject on my QRZ and QSL websites. 4X4XM Doron Tal (Tirkel)

Really appreciate these lectures, thanks for putting in the work to put these online for us.

So I’m wondering why some government websites removed a can use the internet access. I know it’s only in some areas and some cities but on another website but I’m not sure what it would be or kept up with it

Why do intelligent people talk in that annoying beta male voice?

It's beautiful😍💓

Wonderful

Süper👍👍 Hi! I wanna Increase my Art skills🎲🖌🎨✍🏻️ give me your opinion, thanks! 👀

Incomparable

Omfg!! Amazing video You were stunning thanks For Sharing

Wow perfekt sexy i Love it 💘❤💗💗💕🤗😍😘

✌✌Attractive Videos👀

many thanks😎

Ideal💣

Interruptions are very annoying

Fascinating lecture

This is the clearest explanation of phasors I've ever heard, bravo!

Miles - not kilometers - in America.

4:30 don’t forget the magic 🪄🎩

That is incredible. So, you will be able to make devices that do quality control on food products that pass through a conveyor, and automatically be able to reject hazardous meat or produce. Reduced cost of gas detectors in surface and undeground mines, as well as detectors that can analyze samples in real time in the oil and gas industries. Also, this will be a boon for radioastronomy, and 6G consumer electronics. Control dumb devices real time with off board control stations in real time. Hugely important research.

43:38 H2S is extremely toxic, incidentally, for a correction to that chart. The toxicity danger is in fact much more severe than the flammability danger. But other than that, great lecture.

Would the guy that keeps interupting the speaker, please shut up.

Fascinating! Thank you!

The Lecture starts in 35:40

But what about about detecting the big booty Martian women?

Index of near earth atmosphere is very close to unity. In the presence of plasma (equal distribution of positive and negative charge) the refractive index will drop below 1, depending on the frequency of the electromagnetic wave. This is the optics of metals as described in Born & Wolf. The radio wave is reflecting from what it perceives as a metallic layer. One slide in the presentation correctly identifies this as total internal reflection as occurs in an optical fiber, but I don't believe it is correct to characterize this as refraction -- at least not from the perspective of ray tracing and classical optics.

Excellent lecture on a topic I'm most interested in. The very knowledgeable Dr. Lind made the hour + 23 minutes go by rather quickly. A lot of information to process. I did note quite a few topics to follow up on in order to solidify my understanding. I'm compelled to listen to his other session on radar. Making the slides available would be helpful, but I did save screen shots for me to reference.

41:00 My god this thing about "hard tech" hits hard. I've done research and I've been in industry, and only now that I reconsider this idea years later did it become real for me...

1:06:35 gateways?!!

lol this guys voice at the intro is awesome LOL

Poor guy. He tried so hard not to lose his cool. I could not have been so generous.

The guy hawking loogie’s and having a coughing fit in the background needs to think about waiting to watch the talk when the video is released… so distracting.The only thing that could make this worse is if a crying baby was also in attendance 😂
