This was an incredibly challenging video to make. The challenge came with getting the Navy to agree to the interview in the first place, then successfully navigating the interview without it being shut down. In the end, everyone was super professional and it was a really fun topic to learn about! I hope you enjoy, and thank you very much for considering becoming a Patron at (https://www.patreon.com/smartereveryday)!

One additional factor on sound "bending"...add distance. Over great distances, lower frequencies will overtake high frequencies...so it is possible to hear the "bass" notes first enen though the initial emmittance was the reverse of that. (former sonar tech on fast attack sub).

Can passive sonar be used for navigation. Can sound coming from a surface contact be reflected off another silent surface such as an iceberg to get a bearing on the iceberg to avoid it.

Blessed is that servant, whom his lord when he cometh shall find so doing. Verily I say unto you, That he shall make him ruler over all his goods. But and if that evil servant shall say in his heart, My lord delayeth his coming; And shall begin to smite his fellowservants, and to eat and drink with the drunken; The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of, And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth.

issue is though that the Best Depth calculations aren't exactly 'secret' either, and can be found online at the Federation of American Scientists or in a basic sonar physics manual if you've had to deal with underwater sonar at a program level you have to know it because it can interfer with depth sounding, but the calculations change based on depth Best Depth = 17SQRTLayer Depth if the depth is less then 60 meters else it's LD + 60m.

Really love your series - I was ET in Navy... officially trained Radar, Coms and microelectronics but worked on ASW training facility as staff for a while - helped sonar tech (that just swap boards) and operators repair many systems for our aging sonar systems - sure hope they have made improvements since then - I had to reverse engineer many HP systems to rebuild with modern components... anyhow - even old systems have a lot of classified intel - but what amazes me is how many sounds and profiles the USN has on just about everything that has ever been made known to man and how quickly they can identify just about everything on planet earth by acoustic signatures from ambient passive and active sources.

It always amazes me to learn how people learn to read "lines" on measurement machines. I was a paramedic for 2 years before becoming a firefighter and (while this is in a semi-distant past), it was mind-blowing when I first learned how to interpret 3 and 12 lead EKGS. So much information in a graphed line!

There’s was old PC games call Jane’s 688i Hunter/Killer, then Sub Command, and the next is Dangerous Waters that simulate this very well. You can play multiplatform of submarines and also subhunter like Perry class frigates or P3 Orion and Seahawk helicopter. In sonar room, there’s screens and also bathymetry just like in this video and you can play this as you can analize target, find the depth layer to hide from active sonar and else. The information at that game is only “what is this” so all of the strategies you can find out from movies like The Hunt For Red October or browse in the internet, mostly with uncommon scientific languange that hard to understand, than try to simulate it. And it works, you can hide your sub into depth layer shadow zone, you can hide by sailing very close to a cargo ship, you can find friendly or enemy vessels between neutral civilians by reading the graph and analize the their movement, so hard or maybe I can say too hard but it’s very very very intresting when you find how to use that equipment and combat tactics and strategies that can be..... ah you make me miss that PC simulations games Destin, I remember for one simple mission just like out from harbour undetected it was 4 hours sitiing in my PC, 6 to 10 hours for mission like take a peek for enemy vessels activity, and more than 20 hours for a mission like destroying aircraft carrier in a CVN Battle Group. All with no mistakes or error tolerable even in seconds, patiently so challengeing.

12:33 - Why does the bearing rate depend on whether you're closing the gap or not? If you're tailing a contact at a constant velocity that's head-on wouldn't the bearing rate remain straight anyway? Why does closing the gap between them matter in this context? The bearing would still be 0 degrees and time is still progressing.

Especially high school age (think his excitement would be catchy) He has a way that makes you want to know more and teaching, when done right, is no easy task. In fact getting kids to want to learn can be the hardest important career there is. Not anyone can do it. Respect!
