comment Using water filter/purification system on Shabbos
After listening to the shiur that Boruch posted, I perhaps understand your question. You are asking if granule based filters are a problem of borer. But even in a granule filter they never really mix. If you spill the "mixture" out on the floor, all the water will drain away, leaving the granules behind - it doesn't actually mix, just like a wet shirt isn't a mixture.

comment Source for bechorot losing/reclaiming priesthood
This is interesting to me because I heard that once they lost it it's over, that the bechorim will not get it back.

comment What should I do if my synagogue faces away from Jerusalem?
In London you should be facing South East, not just East. So the Aron on the north west is exactly opposite what it should be! Is the Aron built into the wall? Can you turn the whole shull around? For your second shull, don't face East, face South East, so you are not facing the toilets. In London, having the Aron be South is better than North, even if you can't have it face East.

comment Not eating from the Lechem Mishnah
This doesn't answer your question, but if you know before shabbos that you don't have a whole loaf, then you can briefly heat up the piece you have and it counts as newly baked and whole.

Are you trolling? You're not sure what mount means? And can you source this novel definition of God's name?

comment Can members of Hatzalah learn how to deliver a baby?
Seems to me the opposite: Could someone possibly become a member of hatzalaha without learning how to deliver a baby???? I read over an EMT manual and there was a complete chapter on delivering a baby in there, I can't imaging you could become an EMT without learning that.

comment Responding to “that's not a Jewish name”
I think there are two reasons for someone to ask that: Either they are rude, or they want to know the origins of the name. So answer them in that light. If you think they are being rude, then just say "Ok". If you think they are curious about the name, then tell them it's from ...., etc.

comment Is there a concept of time in Gan Eden and the world to come?
So if someone is in Gan Eden for 2 years, this means they experienced a sequence of events lasting 2 years - but since there is no past/present/future this doesn't necessarily take up any time on our world because their experience did not necessarily occur at any particular moment in history - and at the same time it occurred at every moment in history.

comment Is there a concept of time in Gan Eden and the world to come?
There are 3 levels of time: Time where there is a past/present/future (our world). Time where there is no past/present/future - but things still happen in sequence i.e. cause precedes effect (the world to come as humans see it). And time where there is no sequence, and effect may precede cause (time as Hashem sees it). (Posted as a comment since I have no source other than my memory of class from a long time ago.)

Yes actually, carbon tastes good in water, sort of sweet. But in a filter the carbon is in the form of a solid block and stays in the filter, it doesn't really mix with the water, but rather the water passes through it.

No, no filter works like this. The water never has any "chomer" mixed into it. You may be thinking of Flocculation, but water filters don't work that way. In a water filter the water passes through the active material (usually, but not always, carbon) which kind of "glues" the impurities to the material (this is called Adsorption, with a d not a b). There's never a stage when anything is added. The more the water touches the active material, the more impurities get removed. Filters are made to slow down the water to give it time to touch a lot of the surface area and remove all the impurities.

BTW I'm not asking to be annoying - understanding the construction of the filter can help understand what exactly is happening to the water.

So what is this "chomer"? I've never heard of a filter with such a thing. Can you link to any examples?
