Maybe I didn't do a good job scanning the comments, but I'm surprised nobody (not even the article) mentions the NSF certification body.

Taste is important but very subjective. I don't buy a water filter unless it shows up as certified by NSF[1].

A few years ago I almost fell for a "water purification system" on Amazon, with stellar reviews that was supposed to filter out everything. With a baby on the way I figured it was worth the price tag. Good thing I did my research. The water filtration system was not certified or verified by anybody.

edit:

Same thing applies to humidifiers, air cleaners, air conditioners, etc. Don't buy unless it has been certified[2].

Or you could get a conductometer and measure the purity yourself.

I came here to suggest this. Great to hear that someone actually tried it and found it to work.

Did it take long to get your mind to 'get' it? Did the effect fade? What polarization filters did you use?

PepeGomez · 9 years ago

More or less immediately, as far as I can remember. I used polarizers from an old LCD display.

Here's filter #1. [1]

Filter #2 was custom-made. Not sure if that's orderable in small quantities outside of academia. But you could try to find a filter that fit their "naive approach", which would be simple bandstop (aka "reject" or "notch") filter that blocks approx 450-510nm. Just looking around the same retailer, maybe something between these two ([2] & [3]) might suffice for experimenting? Ideally it would fit that range precisely AND have a rather absolute cutoff. I have no idea if that kind of arbitrary range selection is available to one-off buyers, I'm just a fan of color theory. :P

The issue with the naive approach is that it skews the white balance of the results a bit by affecting the M&L cone stimulus as well, but that's a lesser issue for playing around with the idea.

I guess it would work with one filter as well.

I once made glasses that made me see polarization. It made plant leaves look beautiful.

I owned that game, but seems to have misplaced the discs it came on...

There's a HD version on Steam.

It's only meant to intimidate people. There is no way it could serve a real security purpose.

The line between microdosing and tripping balls is thinner than many people realize.

When "even" bees are intelligent enough to teach each other skills, i really marvel at the mental gymnastics/machinery that goes into convincing oneself that humans are somehow a class apart from animals, and it's totally okay to eat them after having kept them pent up in atrocious conditions. Makes mental note to be a better vegetarian

(and FWIW: i'm not being morally superior here: i believe that in reality, probably being vegan is the only morally defensible position, but the flesh being weak and all... And in actual fact, probably even that is a tricky position: by surviving one is probably making the calculated decision (conscious or not) to put one's own survival above the cost of some other's demise.)

I think the more important question is, if even insects can be this smart with their tiny brains, what the hell are our huge brains for?
