Interesting, but kinda hard to believe that the sounds we hear in the forest could be coming from that high up I'm no expert, but if that's true, that's pretty mind-blowing


One thing that I found super interesting when I studied audio engineering is that our ears are very good at determining direction left/right, but absolutely hopeless at working out if a sound is up or down.

This makes their hypothesis a lot more believable to me; I can understand others incredulity.


> absolutely hopeless at working out if a sound is up or down

Easy, just turn your head to the side :P


The article explains that this objection was raised by other researchers, but that the sounds were triangulated to a height of about 250 feet (because they are caused by an electrical interaction at the top of an inversion rather than from the aurorae directly).


Some can play the piano blindfolded. Is it also connected?


No, that is muscle memory. If I play the piano with my eyes closed, I'm not visualising the piano, I'm focusing on the feel and positions of my fingers


This is my experience as well. I would also say that when improvising I’m not really thinking consciously about the movements, but rather the notes I want to hear.


Was really interested in taking VVIQ. My results: "You have a fairly vivid visual imagination known as phantasia. This indicates an average ability to visualize mental images. When you try to picture something in your mind, you can "see it" with a reasonable level of clarity and detail."


Didn't know that introducing these foods early in life can help build tolerance


And here it is highly valued and can help you more


Being able to track progress over time gives me the motivation to keep going..


I love to drink my decaf at night sometimes. Do not think I'm the only one.


Decaf coffee has less caffeine than regular coffee but it still contains a small amount of caffeine. This residual caffeine might be enough for you.


Since he wrote that Coke doesn't create this effect, I guess caffeine can be ruled out?


> Could it be psychological?

I think so. If you strongly associate the taste and smell of coffee with its stimulating effects, your body might react similarly to decaf coffee due to conditioned responses, even if the caffeine content is much lower


A bit ironic how the evolution of technology and user preferences can come full circle
