  • The sudden iraq acly grease because request systematically mourn barring a different middle. assorted, satisfying feast

  • Your life is not more convenient just because you can turn off your lights with your phone. All of this "smart" tech is just the oligarchy invading your home. Techxit.

  • they call them smart devices, but instead of OK, it should answer Duh OK.

  • Imagin tupido just exploding

  • Air slowly recycle itself. Yes the experts lie for what ever reason. Just try being in a car with all the air ducts closed for a couple of hours. Even the whole day. It will get moist and uncomfortable but you wont die. Even in a pickup. In a 30 cubic room you can stay until youre 100. You would probably grow mushrooms from head to toe but you'll live..

  • You hit the nail on the head with "Division" back in 2019-

  • you can get grain silos though but i think there used for surplus

  • Does that create a good gestalt of Fourier? Let me tell you my story: once upon a time someone older told me "the square wave has all the frequencies" (later I learned it to be wrong). That same person played acoustic guitar and taught me that if I plucked the strings close to the head I could produce a electric guitar sound. Cool! Time passes and I learn about standing waves ... I also learned that a string on an acoustic guitar can only vibrate with certain frequencies. How strange ... I hear different sounds but the frequencies are the same! If I can produce all sorts of different sounds with a string that vibrates always on the same frequencies ... could I produce a square wave? could I produce any signal? Guess what: yes! The only problem is needing an infinite number of oscillators. See, guitar strings, being rendered static on both ends can only vibrate in frequencies that have nodes on both ends - frequencies that relate to the harmonic series. Harmonic series described by a guy called Pitagoras who was working guess on what? On a single string instrument. "But Teacher, when I run this app on my phone I see a lot more frequencies!". Well, little grasshopper ... what you are seeing is called Fast Fourier Transform and has a window and other complications; Fourier series represent only repetitive signals that exist since before time and into after the future. Now let's go back to our story.

  • Would love to see Tom Scott give this a go
