There’s a psychology theory called transactional analysis, Fawlty towers is a great demonstration of it. The characters neatly display the different states, basil is either a critical parent to staff or a child when talking to his wife.
Whenever a teacher was ill in school we watched farty towels.
Amen to that. Fawlty Towers simply is the greatest comedy series of all time.
Talking about British comedy
Edit, I will be having that vaccine once I have chance
I approve this list. The Yes, Minister series too.
Dallas (my nearest huge city) was the first PBS station in the US to broadcast Python. Our parents thought we were crazy.
I even like a couple of totally corny shows Are you being served and Good Neighbors (US name)
I watched it on KERA in the 80s south of Abilene in a town of 2400. It was amazing.
I’ve always wondered two things…
that is all…
The “halo” is the the moisture in the air condensing into water at the angle of the shock formed when the aircraft hits Mach one. The shock is a kind of invisible “barrier” where the pressure builds up in front of it (condensing the water vapor) and dropping behind it. The specific angle of this “halo” is a function of the local speed of sound and the angle of a attack of the wing.
The sonic boom happens because as the aircraft is pushing towards the sound barrier, all the sound waves in front of the aircraft get compressed. As it breaks through, the waves get compressed and released quick and we hear it on the ground as a “boom” (similar effect to the gasses escaping behind a bullet in a gun - creating the distinct “shot” sound).
Basically the jet is ejaculating @Edgy. You’re welcome.
you make me smarter and smarter @cyclonengineer! I still dont understand it, but it kinda makes sense.
Think of sound as a wave of pressure (which it is)…that helped me when I was learning it.
What if Santa is real but it’s really Odin
Is that what happens when you have nothing to do but lift 364 days a year?
Can you use a PDE?
I always wonder about how they designed and built the SR-71. Late 50’s/early 60’s tech, no computers, just slide rules and pencils. I know the answer is “with a lot of hard work”, but it just blows my mind every time.
Fun fact: stealth tech was made possible by Lockheed engineers adapting and developing the work of a Soviet scientist, Pyotr Ufimtsev. His work was a bunch of dense mathematical mumbo-jumbo (modelling the reflection of electromagnetic waves off different shapes) that the Soviet government thought was worthless so they let him publish it internationally. It was translated to English and a Lockheed engineer dug it up and used it.
Also the titanium used for the SR-71 (and that plane is 90%+ titanium) was sourced from the USSR through various CIA dummy corporations.
Beautiful plane - what a step forward from the U2. There’s one on the Intrepid Museum in New York that you can get right up to.
Quite literally - the wave equation
Also, the SR-71, being designed to fly at crazy altitudes, expanded so much on the ground that the fuel tanks actually leaked sitting on the runway.
Starter motor for the scram-jet engines was two V-8s chained together.
SR-71 is still the record holder for highest altitude achieved by an air breathing aircraft.
The other night I woke up and was wondering who would win in a fight, a lion or silverback gorilla? Google said the lion would win but then I couldn’t fall back to sleep because I laid there wondering if that was true.
@polo77j and other sourdough fans.
I always thought that geographical location played a major role in yeasts and doughs.
Guess I was wrong.
