- Detonation vs DeflagrationE1
Detonation vs DeflagrationUsually when people see a fireball they are quick to call it an explosion or a detonation. In actuality, what they've witnessed is a type of explosion called a "Deflagration". Many things are deflagrations. Logs burning in a fireplace are Deflagrating. The primer inside the shotgun is actually detonating. Lead Styphenate or Mercury Fulmanide are used in cartridge primers to start the pyrotechnic train in a bullet/shell. The primer itself is detonating, which kicks off the gunpowder which burns in the shell. Any powder detonations occur in the chamber. As the powder burns and begins to push the projectile out (gas seals with the barrel with something called an "obteration seal"). The powder in the barrel is also deflagrating. - A Real Life Haptic Glove (Ready Player One Technology Today)
E187A Real Life Haptic Glove (Ready Player One Technology Today)If you want to know how this marvel works, just watch the next video... it explains Everything you want to know. I chose to break this up into two videos because it was so cool. - A Dragon Torched My Hand (How Do VR Haptic Gloves Work?)
E188A Dragon Torched My Hand (How Do VR Haptic Gloves Work?)There are tons of things I had never considered about how difficult it is to fool your brain into thinking it's touching something it's not. I think the most important technical issue to overcome is timing. Much like how your brain can understand hearing someone's voice AFTER seeing their lips move, but not the opposite... the lag time of the sense of touch is an important thing for your brain. Another thing I hand't considered is the "rise time" that has to do with internal stresses in your fingers. If you conceptualize your fingers as water balloons around bones, you can understand how the internal pressure of your fingers rise the harder you press something. This type of information coupled with the "Sensory Homunculus" make for some incredibly fulfilling thought experiments. The temperature question is something I'm particularly interested in. Using a colder fluid to model a room temperature fluid because of the heat transfer equation is a fascinating area of scientific problem solving. If you think it through, everything about this boils down to differential equations. How much heat is leaking out of the hand, and at what rate, through what contact area? - Circular Saw Kickback Killer (We used science to make tools safer)
E206Circular Saw Kickback Killer (We used science to make tools safer)Technical details about what we're doing: We're working on a time-series problem called a Sequence Classification. Recurrent Neural Networks called Long Short-Term Memory (LSTM) networks are good for that. It’s what they use for natural language processing because it can remember context from the sentence you’ve just spoken. In this case its used to analyze not just the current timestamp of data, but what has been happening for the last 20 - 250 ms, which helps to reject false alarms. - The Future of War, and How It Affects YOU (Multi-Domain Operations)E208
The Future of War, and How It Affects YOU (Multi-Domain Operations)It's a strange feeling to share this aspect of my life. I'm taking a break to go back to school, but here's a peek into the part of my life I've kept hidden from the internet for many years. I was asked if I wanted to film my last mission and use it as an opportunity to explain "Multi-Domain Operations" to the public. After much consideration, I decided that this topic (especially the cyber-domain issue) was important and chose to help inform the public. My mission was to participate in a missile and torpedo engagement exercise at Pacific Missile Range Facility as part of RIMPAC 2018. RIMPAC (Rim of the Pacific Exercise) is the largest naval exercise in the world. It's used to test interoperability and the ability to work as an international force. - Drawing with Sound (Oscilloscope Music)
E221Drawing with Sound (Oscilloscope Music)What I really like about this project is that it taught me to think about the world differently with respect to physical objects. I now sometimes think about the outline of physical objects as if it's a line. The specific area of math that you use for things like this is called "Parametric Equations". I had a lot of great conversations about this stuff with Hansi and Jerobeam. I was very impressed by their intelligence, and also very thankful that they took their time to share these special things with me. I know they'd really appreciate it if you'd reach out to their website and purchase OsciStudio as well as some of Jerobeam's music. Even if you don't have an oscilloscope, purchasing the software will obviously help them continue to do what they love doing. Hansi showed me a very interesting thing he's working on involving ray tracing. It was fascinating.
