I explore the world using science. That's pretty much all there is to it. Watch 2 videos. If you learn something AWESOME, please subscribe if you feel like I earned it.
Contact: www.smartereveryday.com/contact. I currently get lots of correspondence so please forgive me if I'm unable to reply. I mean well, but want to focus on being a better Dad.
All straight eyed lookin dudes. I respect it. Wish I wasn't such a dab addict, although I never would join the military, I always thought flying plains would be dope.
2:05 Destin describes WW2 sonar capability, the smirk on the sonar chief's face is priceless. 7:20 no object "shapes" per se in sub sonar target classification, not necessary to the mission. However, "bearing" (aka direction, 0-360 deg, true/relative) is key and instantaneous from equipment in active or passive sonar. 8:00 Getting warmer, bearing rate is used initially to make sure you're not going to run into something, on the right-drawing-left and on the left-drawing-right objects get your attention because they are 'closing' range (6th grade geometry). The fun starts when the classification and Target Motion Analysis (TMA) kick in. Ultimately, when the tactical sonar picture is complete, the conn (control room, derived from "conning tower") has a 3D mental image of own-ship and target with physical and mental overlays of; nautical chart, threat perception, intelligence and most important - forward thinking; what are we going to DO with that info? Classify it, log it, track it, record it, shadow it, play with it, manipulate it, or maybe kill it. Great work as always Destin. Cheers!
Love your videos! It shows that you enjoy the pleasure of learning, and sharing that learned knowledge. Just q question, can you please tell me the name of the music at the end of your video?
The old "reel" type push mowers actually did use a scissors action. They cut cleanly, but didn't lift the grass up to be cut. When I was a kid back in the sixties, my dad had a gas-powered model and those big exposed blades scared the snot out of me!
Great stuff! @ 20:35 Don't slam those sh!tter doors sir. That's exactly what bad guy sonarmen are listening for. Back in the day, Hammerhead (fast boat) CO got so tired of hearing sh!tter doors slamming he had them all removed from enlisted heads for a whole patrol to get his message across. During the cold war, U.S. fast boats tracked many soviet subs on transients (uncorrelated sub sounds) alone, even using them to predict maneuvers like zig/zag, PD, depth change, etc. Cheers!
8:28 "you busy?" ... that's how every mad night out in my life started... friend: "you busy?" 4 hours later we're in a different country for the weekend
I'm only 1:37 into the video and I'd say it's because of the surface tension of the water changes, either by temperature or adding impurities like oil...
wow....these videos brought back memories for me.....I was able to commission two 688 class submarines during my sub service.......greetings from Philippines
One time when I was trying to germinate Sea Rocket seeds I noticed that the seeds had a strong attraction to any solid objects including the sides of the glass. After much research I learned that this is likely an example of the Cheerios effect albeit a strong Cheerios effect stronger than other objects including Cheerios that I compared them to. I haven’t been able to look at the Sea Rocket seeds under a microscope but I think the structure of the surface of the seeds plays a role in its strong Cheerios effect. This makes sense because Sea Rockets uses water to distribute its seeds and the seeds need to find solid ground in order to mature into a plant. Anyone interested the Cheerios effect or biomimicry should check this out. This video reminded me of that experience being a surface tension related phenomenon.
That Dewalt should have a kick-back brake, did you guys disable it or how did you manage to get it to fly back like that or does it need positive pressure from the user to engage?
I almost drowned and then died of exposure once - a learning experience and entirely my own fault - but at one point, as we were trying to extricate ourselves from the environment trying to kill us, I hit a road and had to work out whether to turn left, to friends, dryness, warmth and safety, or right, to death. And I could not tell my left from my right. It wasn't possible to decide. my brain was shutting down and although I knew who I was, and could walk, I could not think. Much the same scenario I think.
lol at the guy at 9:15 not even a thank you or show appreciation for being served a fresh pizza underwater while serving for the military. Just a grumpy face waiting for his poppers, just like a kid waiting for his happy meal.
I like your video's but I smell BS. You said you went out to help this guy break your record and film it, but then when it gets to the final test and you go to break this record the area that is 700+ ft away is a tall grass area that you can conveniently just say we think he did but who knows... Seems fishy, like why would you not plan to have the area that is that distance away clear to be able to find it. It doesn't make any sense
When learning to play cricket. We are taught to catch the ball ( corky ) by slowing it down, with our bare hands. Instead of the US baseball way of stopping it dead in motion, with a mitten.. Cricket is a REAL mans game.. Just like Rugby.. ha ha ha ha
We also played cribbage but the lower enlisted E6 to E3 played Spades. My favorite was Holdem in lower Missile. As an ET2nd never got to hang out in the GOAT locker.
