> Apparently enough people think electromagnetic radiation in the ears is a problem Even Andrew Huberman, one of the most popular health science podcasters, has dabbled into anti-EMF quackery. On one podcast he claimed that his Bluetooth headphones produced notable "heat effects", implying that the electromagnetic energy was enough to produce palpable heat in his body. It's obviously placebo effect to the extreme (ph…

If Bluetooth headphone batteries can produce significant heat for 8 hours we would have discovered a lot of free energy :-)

Ear warmers and headphones in one, that would be nice

I've never heard this before! When I started flying it was just the 2 mono jacks that you still see on planes that haven't been updated (always wondered why it wasn't just a stereo jack) Pretty surprising to hear there's air/sound tubes rigged on to every seat on a plane. Seems like the sound tubes ended in the 70's: https://apex.aero/articles/sound-tube-surprising-history-air...

> Seems like the sound tubes ended in the 70's I was still encountering them in the early '90s, although by that time they had become uncommon.

I guess the article is written from the perspective of AVID: once electronic headphones became cheap enough, they didn't sell any more pneumatic systems for airlines - but the last planes equipped with pneumatic systems in the late 70s/early 80s still flew (unrefurbished) until the 90s.

I was intrigued to see a lady at the crosswalk the other day wearing earbuds with thick tubing instead of wires. Googling it, I discovered they were "EMF free headphones". Apparently enough people think electromagnetic radiation in the ears is a problem that there are now dozens of these headphones on the market that put the driver half way along the cord, with tubes proceeding to the earpiece.

Well, non-ionizing radiation (NIR) cause cancer has being debated such as this [1]. It wouldn't surprise me that it will be a bit like the Roundup/Monsanto situation. I don't blame people wanting to use these kind of protection just in case.

And iPhone also had this in their Product Information Guide:

"When using iPhone near your body for voice calls or for wireless data transmission over a cellular network, keep iPhone at least 15 mm (5/8 inch) away from the body, and only use carrying cases , belt clips, or holders that do not have metal parts and that maintain at least 15 mm (5/8″) separation between iPhone and the body."

They also use a similar mechanism for the "get me out of here ASAP" panic button [0] that staff place in your hand and tell you to squeeze if required, all it does is detect a change in air pressure on the other end of the tubing. [0] https://www.mriequip.com/store/pc/MRI-Non-Magnetic-Magnalarm...

My house came with a button like that for the garbage disposal. Previous owner didn't like the idea of using an electrical switch with wet hands.

A button for garbage disposal before you have a chance to dry your hands? What does this button do, activate some pneumatic tube system so you don't have to carry trash to the bin?

Completely tangential story. A few months back I was getting an MRI. I stashed my belt, coins, keys, and phone. The machine started its clicking and thumping when I realized I had my wedding band on my ring finger. Immediately my mind raced to a video I once saw of an MRI machine propelling a fire extinguisher across the room. I braced for my finger to be torn off while I slowly took the wedding band off using only o…

I forgot to take my tungsten carbide wedding band off as well for an MRI, nor did the MRI techs say anything. It was in the middle of the MRI scan that I realized it was still on and then my fingers on the ring hand kind of started to feel fairly warm, but not certain it that was actually the ring picking up magnetic energy or if it was psychosomatic, but no harm became of it. I looked it up afterwards and tungsten a…

Tungsten carbide jewelry is a mixture of tungsten carbide powder and a metal binder, typically cobalt or nickel. The metal binder is electrically conductive and thus susceptible to the induction heating you felt.

What are the recent revelations you’re referring to?

ny mag did a hit piece on him which seemed to be without much substance. First I've heard of him, no opinion at all about him.

I found it did have substance. The substance was that he is also a human being, and also flawed in his personal life.

That takes nothing away from his work in my point of view.

I don't understand why we hold impossible standards of perfection and sainthood to successful people.

They're talking about the "trash blender" that's common to be installed in American sinks

Would you or I or anyone look less flawed if they went for us like that? Why believe ny mag? How would the author of that piece look under similar treatment? What consequences are there if the article is shown to be full of half truths and lies? By my reckoning, none. That makes it a hit piece.

He may be deeply flawed, he may not be at all. I have no opinion on it and lack the necessary information to form one, even if i wanted to.

NY mag’s reputation is the one damaged here in my eyes.

I would look much more flawed. I could not withstand the scrutiny of fame.

I do not see his reputation as damaged, I just acknowledge that he is not perfect, something I was sure about beforehand.

Can I know whether the information presented in the article is factual ? Of course not. Is it single sided or even intentionally harming ? Could definitely be.
