The perception of taste is remarkably complex, not only on the tongue but in organs throughout the body.
The idea that specific tastes are confined to certain areas of the tongue is a myth that “persists in the collective consciousness despite decades of research debunking it.” Also wrong: the notion that taste is limited to the mouth.
I’ve seen this exact article quoted several times with the “you’ve been wrong about this all along” and it’s like the people saying that don’t even bother to read. No it’s not saying that lift isn’t generated due to low pressure forces, like you’re claiming. It’s saying that it’s not a complete explanation. It’s missing some forces that make up the rest of the lift.
You can be forgiven for thinking that that’s not how it works 🙃
Like it says, it’s the most popular theory with scientists, they’re just still missing a complete explanation. Lift from low pressure is still the most popular partial explanation.
